Best ROM for launchers - HTC EVO 3D

I love launchers. I love what custom kernels and ROMs can do to your phone. What I want to know; What kernel (if any) and ROM (if any) will make launchers smooth/lag free/fast and extend battery life at the same time. I don't play 3d games and I don't need crazy performance. All I want is for my launcher to be smooth, fast, and lag free and save as much battery as it can while still making the launcher lag free. I don't like sense. I don't like AOSP. or ASOP. Or whatever it is. I like launchers because you can customize it and they just seem better. What do you guys think?

How about a Senseless rom? Check out Scott's Cleanrom with sense removed. Otherwise, I think leedroid tweeks can freeze sense up. Once you have that done, use ADW, GO, etc. Freezing all the sense components frees up ram and processing power, which helps save battery and preserve processing power to keep you launcher smooth.
If you find that you have more power than you need after that, use SetCPU to underclock for more battery, or overclock for even more power. Make sure your rom is based on the 2.17 update too; that really helped the battery out. Using the stock kernel, IMO works best for battery as well.

Since I'm on Hboot 1.5 how do I get the 2.17? Since I already flashed before the update I don't think it will update.

You have to relock the phone "fastboot oem lock" and run the latest Ruu.

Since youll probably miss this if I put it at the very bottom, there is a thread someone started here if you want a bit of inspiration for home screens:

and the official MIUI only homescreen thread:

The absolute best by a HUGE margin is MIUI, and its features match exactly what you are looking for. It is incredibly smooth and has great battery life with very little running services in the background compared to most of the ROMs out there.
Everyone thinks Eternity is crazy smooth, and it does seem that way. But MIUI puts Eternity to shame on smoothness
Here is what I do to get amazing smoothness and battery life (can also just get the apps and stuff I said and look at screenshots at the bottom):
Install MIUI
Install AnthraX A06 kernel (best one yet, PM someone to get this kernel)
download SysTune. Yes SysTune, not System Tuner Pro or any of that. Needs to be SysTune. This is the best tuning app anyway so you should be using it.
download Launcher Pro (I prefer it, can use whatever but Launcher Pro works very well and it uses the same process as a lot of system stuff which is handy later)
download Script Manager
fin and download the V6 Supercharger script, update 9 RC5.2 (it is downloaded as a .txt file, remove the extension so it becomes a .sh file and put it on your SD card)
run script manager in root mode, run V6 script as su (dont select run on boot). Be sure and integrate it into build.prop I think it is. You will be asked this.
select 1000HP setting (option 9)
dont wipe and restart, go back to the menu and select die-hard + OOM groupings
select "engine flush" (option 18)
select "detailing" (option 19)
select to install the nitro lag nullifier tweak (option 20)
now select the "superclean and restart" (option 30)
once restarted open SysTune and change to OnDemand governor
set minimum speed to 192
set maximum speed to 1404
check "apply on boot" and hit apply
go to the governor tab and change to these:
[*]down_differential - 13
[*]sampling down factor - 4
[*]ignore_nice_load - 0
[*]up_threshold - 92
[*]two_phase_freq - 810000
[*]powersave_bias - 0
[*]sampling_rate - 15000
[*]io_is_busy - 1​
select "apply on boot" and hit apply
on the VDD tab select the "-" button at the top 4 times. You can go down more later but for now this is to be safe.
scroll down the list of frequencies and set/make sure the 1.4GHz step is set to "1150000".
Set each of these steps to:
[*]1404000GHz = 1150000
[*]1350000 frequency = 1125000
[*]1296000 frequency = 1100000
[*]1242000 = 1075000​
no NOT check apply on boot. Hit apply. After you have been running a couple hours straight on these voltages then come back and check apply on boot. You dont check it right away in case you set something wrong and it causes a crash from too low of voltage
on the miscallaneous tab change both IO schedulers to deadline
set both read ahead values to 2048
check "apply on boot" and hit apply
set:
[*]sched_child_runs_first - 0
[*]sched_compact_yield - 1
[*]sched_latency_ns - 18000000
[*]sched_min_granularity_na - 1500000
[*]sched_wakeup_granularity_na - 3000000
[*]sched_tunable_scaling - 1
[*]sched_nr_migrate - 32
[*]sched_migration_cost - 500000​
check "apply on boot" and hit apply
set:
[*]swappiness - 20
[*]dirty_ratio - 95
[*]dirty_background_ratio - 60
[*]dirty_writeback_centiseconds - 000
[*]vfs_cache_pressure - 40
[*]min_free_kb - 34133
[*]min_free_order_shift - 4
[*]oom_dump_tasks - 1
[*]oom_kill_allocating_task - 0​
check "apply on boot" and hit apply
in the Renice Process tab:
[*]click on the plus icon and select:
[*]android.process.acore = -15 (this is Launcher Pro, choose your launcher process)
[*]com.amazon.venezia = +15 (if you use and have the Amazon appstore installed)
[*]com.android.mms = -17
[*]com.android.phone = -18
[*]com.facebook.katana = +13 (if you use facebook and once it is installed)
[*]com.google.android.gm = +4
[*]com.teslacoilw.widgetlocker = -8 (if you use widgetlocker. If you dont, why arent you?)
[*]com.touchtype.swiftkey = -20 (if you use Swiftkey. If you dont, why dont you? Ok but select whatever process is for the keyboard you use)​
Select any other widgets you use in your launcher and set things like clock widgets to around +5 priority. Contact widgets and stuff like that to around -5 priority
press your menu button and click on "more", select service icon
change your icon or set it to no icon. I dont use an icon
check "apply on boot" and hit apply
lastly:
press menu and go to settings
in the personal tab, select display
make sure auto brightness is on
click on advanced mode
set Sample Interval to either 1 or 2 seconds, I use 2.
change the light levels to "use custom"
light level to dim = 5
click on "edit other levels"
change the lowest 5 settings to be "2" for the buttons
set up your screen levels like this:
[*]30
[*]42
[*]55
[*]67
[*]80
[*]125
[*]165
[*]205
[*]230
[*]255​
Set up your brightness levels under the "Lower" area like this:
[*]0
[*]35
[*]50
[*]70
[*]105
[*]350
[*]600
[*]1200
[*]3500
[*]7000​
Then click on "Save Settings"
oh and finally, in settings under the launcher category, make sure keep launcher in memory is turned off
Once you have everything going you may want to use that battery calibration script from the same place you downloaded the V6 Supercharger. It is the best calibration you can get.
You may or may not want to install the "super zip" made by il Duce. I like it since it includes an mms.apk file that auto splits messages at 160 characters so texts dont throw and error at you and spaz out when you send a long one. But you dont have to use it if you dont want to. In the current version of the ROM and super zip there are two small bugs where pressing the wifi button in the dropdown menu will cause a reboot and also your time select when setting an alarm is bugged. You can still see when the alarm will be set for it is just slightly harder to set since some of the numbers are covered up by a bad graphic. Other than that, no bugs at all that I can find.
My battery when I barely use my phone has lasted 3 days on one charge. When I do use my phone it easily goes all day long and I still have 30-40% battery by bedtime. If I am going crazy on usage, it still lasts me from when I wake up till I get home from work.
I know that was a HUGE amount of steps and settings and takes a bit of time. But once you know it all you can do it in like 10 minutes and you never need to mess with the stuff again. Trust me when I say the setup is well worth it and nothing even comes close to the smoothness

Super Zip v32 (thanks il Duce)
http://db.tt/GmmA7xzM
What Super Zip does:
- ES (MIUIsettings.apk from 12.30 in /data, launcher2.apk from 12.30, SystemUI.apk from 12.16) - Andy Thomson
*note* overscroll actually works fine IF your framework-res.apk OR theme.mtz includes it already
- MiuiCamera.apk from kaos420 - no FCs
- newest market 3.4.4 plus speed hack - me
- newest google defaulted to search button - liquidsolstice
- OLD sprint VVM app (no idea if this will fix anything) - me
- volume+ from 12.30 (long press vol for track skip screen off) - Andy Thomson
- remove debug icon - jdeloach
- remove "no service" when in airplane mode - jdeloach
- kickass d3rp screen transitions - me
- added back in old DSP manager (no FC) - kaos420
- added back in gallery 1.0 (no FC) - miui
- added fixed qHD torch.apk - jdeloach
*note:
you can get better battery life by only maxing your speed at 1.18GHz instead of 1.4GHz
Also by changing your sampling rate in the governor to 25000
and by changing the up_threshold to 95
I included screenshots of my settings so that you can all see them first hand. I normally use a bit lower voltages too but I upped them for these shots to show levels most people have said work well for them. In my battery shot, youll notice today was a light day of usage. I only sent about 100 texts and made 4 or 5 phone calls and didnt play any games today.

1. Thanks a million.
2. I hope you didn't type all that out for that specific post. I hope you copied and pasted.
3. Thanks a billion.
haha I will do this for sure. One thing though, I have a SEIDO 1900mAh 3.7V Li-ion battery. It seems better than stock. Will the battery calibration script work for this battery?
I have been at work since 330am. It is now 130pm. Sent only 50 texts. 1 quick phone calll. I think I got on the internet for 5 minutes. My battery is down to 65%. Is this good?
Up time: 73:08:20
Awake time: 37:28:39
Display 75%
Cell standby 12%
phone idle 10%
voice calls 2%
Android OS 2%
Seems like it shouldn't be down to 65%. But it's better than nothing. It will get me through the day. With very light usage though. I don't usually use it this little.

lol actually I typed it up just for this post, but I needed to anyone since another person was asking me to do it for him too. Now I was able to just link him here and save everything I typed up for future linking to people who want it
Yes the battery calibration will work for any battery on any ROM. It monitors your actual mili voltage level of the battery and gives you precise instructions for how to perfectly calibrate the battery. It also shows you what it is being read as, and what level it should be at perfect calibration so you know how far off you are. Batteries have different capacities but all the batteries for our phones are supposed to be at a certain voltage when full and drain in a certain way as they discharge, this lets you calibrate it perfectly for how it should be
That seems like a bit high idle drain to me. I did that same thing today so far with usage and have been on battery almost as long as you and I am at 86% right now. with the ROM, kernel, and settings I posted.

Those are a lot of steps. I'm a noob still so don't lose this thread. I will most likely need your help at some point. If not, I will still probably have questions. Thanks again. Will post back soon.

miui doesn't have 4g so I'm going to try cleanrom

[BOOST] Give your X10 a REAL boost! [Performance and/or Battery Life]

I'm not responsible for any problems caused by this on your device. It's your choice to apply these simple tweaks to your phone!​​
---------------------------------------------------------------------------------------------​
[These apps are NOT paid! Only setCPU is paid, you can get it from the Android Market! (All apps provided here are downloadable in de Android Market)]​
---------------------------------------------------------------------------------------------
-- You need to root your x10 to use these apps! --
Click to expand...

---------------------------------------------------------------------------------------------
If these simple Android Market apps, cause any problems on your device it means you've got something unstable installed on your device! I never had problems with Autokiller and AutoRun Manager on any ROM.​
Hey,
In this thread I will show you how to get a REAL boost on your Sony Ericsson XPERIA X10! This method could also improve performance and battery life on any other handset. This is compatible on Android 2.1, 2.2.1 and 2.3.x. (This way of boosting performance is without Systcl config! I suggest you to uninstall Systcl config, since it doesn't improve anything for me (and maybe for more persons here). I don't recommend you to use Autokiller on WolfBreak his CyanogenMod 6.1.3. He has already implemented these settings and also don't use this on Gingerbread Custom ROMS for the x10. Autokiller is not stable on it anymore. Just wait till I report more about it.
This method made me lose 0-2% in 9 hours on WolfBreak his Cyanogenmod 6.1.3 and ALL 2.1 ROMS! These simple apps, did improve my performance and battery life!
---------------------------------------------------------------------------------------------
Lets get to the point
Download this and this package, put in on your phone and install them!
Lets config it now
---------------------------------------------------------------------------------------------
Open Autokiller.
Go to the tab Memory limits.
Now put these configuration into the 3 boxes. (If these values cause problems you can try lower values I will provide)
Hidden app: 150
Content provider: 160
Empty app: 170
Now press on Apply.
Lower values (Only use when you get problems with high values):
Hidden app: 82
Content provider: 90
Empty app: 92
Now press on Apply.
(Don't put these values listed above higer. If you do your device can start to malfunction)
Now press on the Menu button on your Device and tap on Settings. Now make sure Apply settings on boot is turned on! After turning it on, press on Advanced system tweaks. Now make sure that Battery and Memory management are turned on!
Exit Auto Killer by pressing the menu button and reboot your device.
---------------------------------------------------------------------------------------------
Now open Autorun Manager.
Now make sure every service that is listed in the tab Basic you don't need is turned off! Make sure you only turn off things in the tab Basic! After doing that, exit Autorun Manager with the Menu button and reboot your device.
---------------------------------------------------------------------------------------------
This configuration only effects you device when your screen is turned off. Don't expect with this setCPU very big changes! But there will (must) be some changes in battery life) (Some people had big changes)
The settings here below won't cause any lag when coming from sleep (atleast for me). Even with heavy apps.
[To get the XDA-free version of setCPU take a look at this post. Credits for telling this are going to DooMLoRD]
This step has a payed app. You can buy it from the Android Market. The app is called ''setCPU''.
Buy setCPU from the Android Market. Now open it and do the following:
Tap on Show Other Frequency Sets and tap on the list on Nexus One/Snapdragon [QSD8x50]. Put
Now press left in the corner on the tab Main. Put in the scaling bar the maximal frequency on 998MHz. Now put the minimal frequency on 245MHz.
Now press on Scaling and choose out of the list Ondemand, after pressing on Ondemand turn ''Set on Boot'' on.
Now press on the tab that you can find next to Main. It's called Profiles. Make sure that ''Enable'' turned one and Notifications turned off. Then press on Add Profile. In the Edit Profile window you have to put the following settings:
Profile: Screen Off
Max: 384MHz (Don't put it lower or it can cause malfunctioning!)
Min: 245 MHz
Scaling: powersave
Priority: 100 (High)
Then press Save.
Then reboot your device and enjoy!
---------------------------------------------------------------------------------------------
Your x10 is now fully optimized with a few simple apps! Not only the battery but also the performance! Most people think it should improve battery, it's only more for performace. It can improve your battery.
And... Don't forget to press the ''Thanks'' button instead of saying Thanks in this thread
If you liked this and are able to, please donate to me
Have fun!

Interesting. Hard to believe the 0% in 9hours. I think that's massively exaggerated. Cellular standby at the min uses 0.5%-1% per hour. Even if you didn't turn your screen on during that entire 9 hour period, you would still have a drop of about 5%-10% in batt life.
But I'll bite and give it a test.

I didn't touch my phone in those 9 hours. I was just sleeping with alarm on
Looks interesting, but shouldn't be in the development section.

Yes, that's what I was saying, even then, cellular standby would eat up 0.5-1% of batt life per hour. Could be much higher if you're on a fringe area of your nearest tower among other factors. In a 9 hour period, in just standby and in perfect conditions it should have at the very least dropped 5%.
I mean this is just the nature of the beast with devices. Only way around this would be airplane mode, phone in sleep mode and not being used at all. Then the phone is pretty much dead and you might as well just have it turned off. Even then phones that are turned off actually bleed batt life. Albeit at a much slower pace, they still discharge while completely off.

set cpu settings

what is the best setting for our SGA?
There are no best settings!
It depends on how you use the phone & how you want it to behave. You can use it to improve performance or to save battery or both.
Hit thanks if I helped!
well, u can use some profiles.
press profiles tab, then add profile.
in that select a profile for screen off and set the max to a lower value as we dont use the phone wen the screen is off. This saves some battery. priority:100
create another profile for incall and set the max to a medium value. priority:99
and another profile for temperature>44, set a medium value. priority:98
another profile for charging usb. max slider at medium value. priority:97
profile for battery<21%. max slider at medium value. priority:96
profile for battery<6%. max slider at lower value. priority:95
note: min for all profiles set the lowest. untick stay awake in settings => development.

well the setcpu settings which i suggested r jst a part of saving battery. U may get few hours more battery. But if u really want to save battery, here is wt i do
-Battery calibration has to be done. "Battery Calibration" app for the calibration:
https://market.android.com/details?i...=search_result
-I use "Juicedefender ultimate"(Just google it and get a pirated copy if u dnt want to buy) - set to "Balanced" profile: (there is a free version, too). Bt ultimate is the best
-"Autostarts" is great for preventing useless apps from autostart. Use it to disable apps wich wil autostart.
-"Auto memory manager" is a great replacement for "Task Killer"( Task killer just kills all apps so they could start again in the background - useless!) Use it in "agressive" mode, apply the mode once and forget about it (and task killing):
-DISABLE automatic syncing and background data!
To save battery, turn off wifi & bluetooth when you are not using them.
- Install APNDroid, to easily switch 3G/EDGE data off when not needed (still allows you to receive MMS messages when data is off, and has a widget)
- Set your screen to the minimum brightness that you can (but so that the display is still bright enough to use)
- Turn off "Power Saving" in display settings (actually uses more power than it saves 9 times out of 10)
- Use auto memory manager
- uninstall 3D gallery(uses lot of battery). instead use "quickpic"(very very fast for viewing images)
-Exiting apps using the back key, home key put the apps to background task.
-use setcpu profiles wich i suggested
I do all of this, and I can get up to 2 and half days(sometimes 3 days) use without charging
Things that will drain your battery the most (highest power usage):
- Wifi
- Bluetooth
- 3G/EDGE
- Screen
- Phone calls
thanks man lets see if this will work.

ICS and battery life Tips tricks and info

Hi all,
I'd like to start a thread here to discuss ics and battery life, maybe we can share some tips, tricks, new ics apps and general info to extend the battery of our phones.
I update to ics last nite on a full battery and when i went to sleep i turned wifi off, i noticed in this morning in battery usage graph that something kept the phone awake all nite, this never happened before, anyone have any idea or experienced the same thing?
Feel free to share anything that will help!

First trick ( note that you need root)
If you keep screen locked for a lot of time you can set min , cpu freq to 192 mhz and safe 25 mV (note that normally when you will unlock the screen , frequency will be higer than normal [100-200 mhz not 3Ghz :cyclops:]
a couple of tricks
non root
- disable all the different data options all the time if you not realy needet and able
- if your not on the internet: dissable WCDMA - GSM is highly enough to phone, send SMS, Email and stuff
- take a dark (best is black) Wallpaper and use a minimum of Brightness.
- use not a lot of Widgeds thats updatet all the time
- just install needet apps... kick out all your unneedet apps
- Dissable all animation gimmiks
- DONT USE AUTO TASK KILLER
- Disable auto Rotation
and for root users
- like Forzaferrarileo, set CPU profiles that press if the Screen is of, the Frequenci to a minimum
- Use the Conservative Governor and maybee use a lesser maximal Frequenzy
- if you use the Rom Toolbox, set your Sysctl Tweaks under "kernel tweaks" into something like
Min free bytes: 2048
Dirty Ratio: 90
Dirty Background Ratio: 60
VFS Cache Pressure: something between 10 and 20
- under Build.prop Tweaks set
Scan interwall to the max (300)
- Download Droidwall and block for the apps they dont realy needs internet the 3g option (dont save just a bit of battery, also saves Download and can made free apps free of adds )
- Dissable the Autostarts and the bootrecivers from apps you dont realy needs often (also with the rom toolbox)
Battery life post ICS is a lot better. I'd say its comparable to .73.
Here's why:
Using .75 FW whenever I would charge the battery to 100% and then unplug the phone from the charger, it would start draining almost immediately. Even on very light to light usage it would drain about 30% in 24 hours or so without any fancy apps that would want to use the data connection or CPU.
ICS: the phone is fully charged, battery drain when the phone is in standby is so much less. In 4 hours of standby time with data on the battery has drained 0% The behaviour of the battery feels very similar to .73 FW which I felt was a great update.

PPL lets get back to reality!
If you need a smartphone that:
- Is 24/7 online
- Contineously synchs e-mail
- Is always online in Vyber, Skype, etc
- Contineously refreshes your widgets
- Surf the net
- Play your favorite 3D games
and you require the perfect battery life, there is only one solution!
MOTO DROID RAZR MAXX!
No other smartphone can perform all above combined and have good battery life!
Lets get real for a sec!

not at all... with this tweaks (without trigger the CPU to a lower level) if got with all my devices that i ever have the most exiting power... all my devices range under the top ten by the Antutu Benchmarktest - with mutch more Batterylife.. because, with this tweaks and Manual settings for Data options, you just use Battery at the time you need it
what is the sense of WIFI, Bluetooth, GPS, WCDMA is on while the Device is in the pocket? for nothing, expet for Battery drain.
Has anyone noticed that something is keeping their phone awake all night? or is it just mine?

never notice something like that - is it while you load your battery? (then i would say it has something t do with the most usless app of the history of Smartphones: the unpluggedchargerreminder)
NO i don't mean litterly awake i mean if you look at the battery usage screen and tap the graph to change the screen you get the 4 bars at the bottom and my one i turn off wifi every nite and so on but the awake blue bar is full?? is it ICS i wonder?

Dont got that problem.
In airplane mode my phone lost 0% battery in 6 hours while i was sleeping.
Also the new power saver app on ics is crap....on gb it wasnt so bad usually lost about 4% over nite
I find this app quite good:

Well it can easily be said that Smart Phone is not Smart enough when we talk about energy consumption. These Mobiles are designed for Charge as per Usage and claim of Manufactures are away from Reality.
We actually waiting this feature when our Smart Phone will give us Smart Battery Life at least of one Week in normal usage...
Think if I have Amoled or SLCD Display than why can not we we use to see a Picture in Brighter Mode to Save Battery?
If I Want to stay connected with the world than why should I turn off GPS, WIFI, WCDMA or Mobile Data?
No Moving Part but Battery got empty every 12 Hours?
Has some fancy features but on the cost of battery..
These are because we wish to have all Goodies and feature of PC in such a Tiny Device suppose to have a auto recharge mode using wind, light power
Limitations are there so on date we can not say it a SMART PHONE has some extra ordinary features but not a Complete SMART DEVICE.......
Don't forget about dalvik. Android isn't pure software. Its more like virtual machine. Because of that lots of energy is wasted and there is need for strong hardware...

seems i dont have much problem on my xperia sola ics, ill share some of my tips(battery life)
first thing, turn off wifi, mobile data, bluetooth, nfc, glove mode, sony bravia engine, and the animation. also dont use live wallpapers on your screen. only turn on if u realy need it
i usually charge my phone between 24-28 hours!
i recomended also not playing games every time..(actually i dont play game on my phone)
hope that will make your batterys life longger too and sory for my bad english..
I don't have any problems with my XPERIA P neither; phone lasts 2days easily and can last 3 when I don't use much (every day I use Wifi and 3G not heavy use but quite good), I just disabled Synch and activated advanced sleep mode for battery (loses 1% overnight)
noob.fl said:
a couple of tricks
non root
- disable all the different data options all the time if you not realy needet and able
- if your not on the internet: dissable WCDMA - GSM is highly enough to phone, send SMS, Email and stuff
- take a dark (best is black) Wallpaper and use a minimum of Brightness.
- use not a lot of Widgeds thats updatet all the time
- just install needet apps... kick out all your unneedet apps
- Dissable all animation gimmiks
- DONT USE AUTO TASK KILLER
- Disable auto Rotation
and for root users
- like Forzaferrarileo, set CPU profiles that press if the Screen is of, the Frequenci to a minimum
- Use the Conservative Governor and maybee use a lesser maximal Frequenzy
- if you use the Rom Toolbox, set your Sysctl Tweaks under "kernel tweaks" into something like
Min free bytes: 2048
Dirty Ratio: 90
Dirty Background Ratio: 60
VFS Cache Pressure: something between 10 and 20
- under Build.prop Tweaks set
Scan interwall to the max (300)
- Download Droidwall and block for the apps they dont realy needs internet the 3g option (dont save just a bit of battery, also saves Download and can made free apps free of adds )
- Dissable the Autostarts and the bootrecivers from apps you dont realy needs often (also with the rom toolbox)

Long Battery Life Fixed for all ROMs

Think I have a solution for short battery life for Nook! (Really for any android device)
The problem has been that the Nook Tablet does not go to a Deep sleep (even if they say its fixed its not). Every night I have to charge the Nook battery because it goes from 100% to 90% overnight. If the Nook sits all day with no use the battery will drop to 85%. Almost a 20% decrease in power in one day of no use. By the second day battery is down to 50% and forget it if I use the Nook.
This app seems to solve the problem!
I downloaded a free app (Google App store) called “CPU Tuner (rooted phones)” you need to be rooted but for most of us here this is not an issue.
This app allows you setup CPU speed, WiFi and other settings for different states the Nook may be in.You can setup several triggers but I only used 1. The problem is not just having the Nook go into Deep Sleep but to turn off other functions that hit the battery e.g. WiFi and sync. With this app you are able to tell the Nook to go into Airplane mode as well as turning off all other features that may consume battery life. Below is my setup and findings.
State 1: “On Power (Plugged in)” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive
State 2: “On Battery” WiFi on, Sync on, airplane mode off and CPU set to 1020mhz Governor set to interactive (same as above)
State 3: “Screen off” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative
State 4: “Screen Lock” WiFi off, Sync off, airplane mode on and CPU 600mhz Governor set to conservative (Same as above)
With these settings (and having 3 nooks with CM10 to test) here are my numbers
test stared around 10pm
Nook 1 started with 76% batt (CPU Tuner not installed)
Nook 2 started with 85% batt (CPU Tuner not installed)
Nook 3 started with 90% batt (CPU Tuner installed)
checked battery life at 8am next morning.
Nook 1 65% batt
Nook 2 75% batt
Nook 3 91% batt (Yes it went up 1%)
Later in the day with no use 8pm still 91%
Loaded CPU Tuner on all three Nooks started test at 10pm. (Day 2)
Nook 1 started at 96%
Nook 2 started at 74%
Nook 3 started at 83%
Checked battery life at 8am next morning.
Nook 1 ended at 96%
Nook 2 ended at 75%
Nook 3 ended at 83%
As you can see this is a big difference then losing 20% power overnight. Since I have Screen Off and Screen Lock as the same trigger I don’t lose power if I am just checking batt level or the time.
This is a MUST HAVE APP. easy to setup and makes a big difference.
You can also setup it up so that if you are on the battery the CPU is at 1008mhz which will save battery life while in use and when plugged in CPU can go to 1020mhz giving you full power.
Sorry for such a long post but I felt it was good info for the users.

Terrific recommendation. Was easy to set up and works like a charm. No more finding my Nook with a flat battery after ignoring it for a couple of days.
Gracias! :good:
Thank you for the tip! I will make a note of it so I can use it if/when I need it! It seems very handy to be able to set upp different user schemes!
However, I do not agree with this comment:

I do know it's a problem in some ROMs, and often a problem along the way during development. I think it's grocely unfair to suggest it's a general problem though.
I'm running a CM10 build from 1231 and I have not problems what-so-ever with battery life! I hardly loose anything while on standby (wifi off). I do turn it off manually, and I understand that with this app I can have it done automatically which is very neat, so might use it because of that. The processor speed adjustments works just fine anyway in the ROM i use.
It's great to know this thing exists and does work if I want to try a "work in progress" ROM more extensively. So once again :good:
The "battery-drain while asleep" problem got fixed since early December (e.g., Succulent's v12/08 build).
Also, I simply turn off WiFi (using a WiFi on/off widget) when I am not accessing Internet, and my NT's battery consumption while asleep has been well below 1% a day (comparable to that of my Google N7).
Finally, for those who are interested in battery consumption management tools, I find Battery Juice Defender (which I use on my Samsung GS-II phone) reasonably effective yet easy to use.
Sorry it was not meant to be a dig or insult!!!
I love ALL of the work that the developers have done and I think I have changed my ROM about a half a dozen times because I can't figure out which one I like best. But compared to my wife's Nook with just the B&N ROM her battery could last days where my battery only lasted 1 day.
Please; I did not mean anything insulting with the comment and the fact that these developers can put together such solid ROMs is saying something about their skills.
How I found this App was from posts here where users were saying that they had to turn off WiFi. Trying to make a WA or KA (WA = Wife Approved and KA = Kid Approved) I know that going in and turning on and off WiFi was never going to happen.
When installed the CPU Tuner and found that it was going to do this automatically and on top of this battery life goes from 1 day to several days I had to make a comment. Only after a few days of my kids using the Nook with the CPU Tuner they made comments about how long the battery lasted. Using these ROMs and CPU Tuner made the Nook 100% WA & KA and now wife is using Nook with the Hashcode ROM and I have heard no complaints. Happy wife, happy life.
Again sorry
Can you post screenshots of your settings from the start, there are some things in your OP that i can't get to setup for testing purposes, indeed the battery of my nook using @succulents ROM 4.1.2 final drains battery considerably while sleeping.

V;
I have uploaded the screen shots. All settings can be changed after loading so if you select the wrong item its not a problem.
I try to keep it simple, You can have more then 1 configuration but as you can see I just use 1. I set my user experience to Normal which can be changed in the settings.
Once you start CPU tuner you will see the current state of the Nook. You can select a different state. (Note the battery was at 52% which has been at 52% for about 2 days and just charged it this morning.)
Next you will see triggers; here you set what Profiles you want for different states of the Nook. Just tap in that section. I forgot to take a screen grab. But I have battery at 100, "On Battery" = Normal, "Screen Locked" = Powersave, "Screen Off" = Powersave and "On Power" = Performance. "Battery Hot" = Powersave and "Call in progress" = Performance. I really only need two profiles Performance and Powersave my Normal has the same settings as Performance and my Screen Off (which I don't use) has the same setting as Powersave.
Next are the profiles. tap the profile you want to edit. See screen shot 7-10 these images have my profile settings. I don't trust airplane mode to really shut off all that I want off so I make sure that things I want disabled are disabled and when I go into Performance I disable airplane mode and enable WiFi (Not sure what Background Sync is or if it even works on the Nook most times I keep it off especially for the "Screen Off" and "Powersave" profiles)
For the governors I leave it as interactive for "Full Speed" and "Normal" settings and conservative for "Save Battery" and Extreme Save Battery these may be the default I am not sure.
If I wanted to really go crazy. I could set my Normal CPU speed to 1008mhz to save battery life while on battery. I could also setup it up that if I have 100% battery use Performance Profile and when the battery level drops to 70% use Normal profile (with CPU at 1008mhz) and when the battery goes to 60% then create a new profile which lowers the CPU speed even more. But with my current setup I am very happy and the fact that after a few days of no use the Nook still has the same power level from when I last had it on.
That's about it. If you have any questions let me know.

Is there any way to delay (eg I want it to wait 5 min before turning the WiFi off)? Or should I use tasker or automateit for something like this?

You can setup a profile where if you press the power button the CPU speed is reduced and turn off all features except WiFi. I believe that after 5 minutes (or what ever time you have set for "Sleep" I believe the default is 2 minutes) the Nook will go to sleep and all features for Sleep will take over e.g. No WiFi.
This will give you two Power options:
1. let the Nook go to sleep on its own after 5 minutes (Screen would be on during this time killing battery life)
2. Press the power button and screen turns off but WiFi is still on and after 5 minutes sleep all features off.
You can monitor what it's doing by pressing the power button and waiting about 6 minutes. Then go to the CPU Tuner log (shift pages to the left until you see the log page) What you would want to see is the following:
11:08am ALL-> Performance
11:07am All-> Powersave
11:01am All -> Screen Off
11:00am ALL-> Performance
Please note that since the time is only shown as hours and minutes it possible to see settings with the same time stamp.
Good Luck.
If you have any questions please let me know.
Fantastic, exactly what I am looking for :good:
I must say that the OP was very good, and CPU Tuner is a great app ....
but times, and apps move on.
currently I use the free "Battery Doctor" from Google Play which does what Tuner can do, but in a much user friendlier way.
my tablet only loses 1 to 2% overnight and still has 80% or so left if not used for a few days.
the developer also has a great file cleaner utility which i also use, and the Task Killer, and memory cleaner widgets you get.
in my opinion they are MUST have's, and I no longer even use the paid version of Juice defender that was my favorite app.

I'm running CM11 Snapshot M3 and haven't been able to find a user friendly way to automatically get wifi off during sleep.
The built-in "turn off wifi during sleep" setting does not seem to be working.
Battery Doctor (Battery Saver) doesn't seem to work well on this ROM. After installing, it would seem to let me change the screen brightness (the slider would move), but then it would revert back to 20%. The app then crashed, and attempting to run it again after rebooting results in a black screen of death.
I've tried a couple other apps like WiFi Auto-Off and Advanced Battery Saver - Free, and neither succeeded in shutting off wifi during sleep.
Granted, I did not try CPU tuner with this ROM. I've tried it in the past and found it very unfriendly.
Anyone have a user friendly method to automatically get wifi off during sleep on CM11?

I decided to give CPU Tuner another shot and it seems to work some of the time. I haven't been able to figure out what the difference is between the times it works and the times it doesn't.

I just use the available quick toggles in CM11 to manually (1) switch off WiFi and (2) go to sleep.
Yes, there is a quick toggle for go to sleep.
I've pretty much have gave up on ever having great battery life on my Nook. Just the nature of the beast Still a great little tablet
Since all those apps automate disable wi-fi when system sleeps and you won't get any notifications if android apps. try to poll data from internet, I just set wi-fi to automatically turn off in android wi-fi advanced menus, there is no need of any of those apps since android system can do the same thing.
Nookt Tablet goes Nuts less than 50% Battery
Currently running CM 11 snapshot 5
Whenever my nook gets below 50% battery it goes nuts. apps open themselves, then shut down, windows open, if I am watching a video it stops then begins at the beginning. Weird.
Have had this issue before and was hoping with the upgrade it would stop, but no dice.
Help?

I have the same issue with my Nook Tablet. I will get to about 43% and it flips out. Apps opening, settings opening, Apps close, airplane mode comes, etc. I have to plug it back in to undo the mess and continue using it. I've had this issue with AndoidForNook's builds as well as the CM-acclaim 10.2.1 build.

[Q] Root Ematic EGQ307BL

I just bought an ematic EGQ307BL tablet. It comes loaded with 4.2
I would post a link to the tablet but the site won't let me.
Do any of you know a way to root this tablet or load 4.3 or 4.4?
I am knew to the whole rooting thing, any help would be greatly appreciated.
Thanks,
Jeremy
I also need root for this device
First I would just like to say hello to all of the incredible developers we have on this site. I've followed along for a very long time and I've finally decided to create an account. I know that you guys are the best at what you do. So, with that said, please help us root this device. I know you can do it. Leapinlar, can you or Verygreen help us with this, or are you strictly Nook developers?
Thanks
I would also like to know if this is rootable as it seems to be a pretty good deal right now at Wal-Mart. It has decent specs @ a decent price.
Ematic-HD-Quad-Core-7-Tablet-8GB
I just picked up this tablet for my mom for Christmas and decided to play around with it. For the price, it's not a bad tablet at all. Screen resolution is crappy but for a first tablet for my mom, it's just perfect.
It's surprisingly smooth with no real noticeable lag but I did a Quadrant benchmark test and my Tegra 2 [dual core] Viewsonic G-tablet actually benchmarked higher. Albeit the G-tablet is rooted and ROM'ed, overclocked to 1200mhz along with a bunch of other memory tweaks, it's getting solid 3100's while the All Winner's [quad core] Ematic is only scoring around 2700's. Still happy with the Ematic though.
Before I forget, I managed to root the Ematic in under 5 minutes and that includes tracking down a spare SD card. I haven't been very active in the forum so it won't let me post the link but just go to freaktab.com>click forum>scroll down to Ematic Tablets>Root directions are under "Quick and easy Root for Ematic EGQ307 series"
The worst thing about the tablet is the battery life while you're using it. I can literally watch the battery percentage going down a percent increment every 10 to 15 minutes. Here's a few things I did to save the battery while the tablet is on but the screen is OFF (standby mode):
- Turn off location access - Settings >Personal>Location Access>Access to my location> OFF
- Turn off sync - Settings>Accounts>Google>Select your account and turn sync settings to off (deselect all options - you can always manually sync by clicking the 3 dots in the top right of screen and selecting "sync now")
- Advanced Wi-Fi settings - Settings>Wireless & Networks>Wi-Fi>(click the 3 vertical dots in the top right of screen)>Advanced - Uncheck box "Network notification"; Also click "Keep Wi-Fi on during sleep" - select "Only when plugged in"; Finally for "Wi-Fi optimization" check the box to "minimize battery usage when Wi-Fi is on
- Data usage setting - Settings>Wireless & Networks>Data usage>(click the 3 vertical dots in the top right of screen)>Check the box "Restrict background data" - Note: You are still able to get on the internet through Wi-Fi, background data is not needed.This is the biggest contributor to saving your battery/screen off.
- Turn off sync settings on other email. You can always manually sync by refreshing your email
* Doing the above settings has enabled my battery to stay at the same level for over 8 hours (while in standby mode/screen off - whatever you choose to call it.) I left for work in the morning with my battery on 93%. Came home in the early evening and the battery was still on 93%
Miscellaneous Tips
- I also suggest using the app Juice Defender but I found it wasn't absolutely necessary
- The obvious settings: turn brightness down; sleep after 30 seconds; turn Daydream OFF; No live wallpapers
- Do 2 to 3 full charge and discharge cycles
- I highly recommend going with a different launcher. The stock launcher was running 2 processes and taking almost a 100Mb of RAM between the two of them. Apex or Nova Launcher use far less.... around 20 to 30Mb depending on your settings
- Enable Developer options - Go to Settings>About tablet>Build number - keep clicking the build number and you will see a count down to open Developer options. Once inside Developer options (if your into speed and not animations) - scroll down to "Window animation scale", "Transition animation scale" and "Animator duration scale" - Turn all three of them OFF (default is 1x)
*Note: if you're into higher benchmark scores, while your in Developer options, scroll down to "Force GPU rendering" and check the box. This will increase your 2d scores.
To increase your 3D scores do the following very carefully.
Download ES File Explorer in the Play Store. Open the app and click the top left of app (looks like a phone in front of a sphere) Select Tools>Root Explorer (turn ON) - Press and hold the word Root Explorer for 5 seconds - another screen opens. Select "Mount R/W" and select RW for "Path" and "system" - click OK
Press the top left option you clicked earlier (phone in front of sphere): Now scroll to the top and select Local>Device>system>lib>egl - Find the file named libGLES_android.so
Long press on the file to select it. On the bottom select "Rename" - simply change it from libGLES_android.so to libGLES_android.bak
Long press on the file one more time to select it. On the bottom select "More" and then "Move to"
Select the 1st option (there should only be two, the first one looks like a phone and the second one looks like an SD card), then select "system" and finally click OK
*Note: Doing the above steps increased the frame rates in Quadrant 3D benchmark scores thusly increasing the overall 3D score. I've done this simple tweak on this Ematic, my Viewsonic G-tablet, my rooted and ROM'ed LG Optimus S and it increased the 3d scores on all of them.
I've done more tweaking than what I've listed here but I hope this little bit helps
Could someone provide a ROM dump of the firmware on this tablet after rooting it? It might help me sort out some issues I'm having with my NB07.
Thanks
Couldn't figure out how to root when developer options wasn't showing up. Thanks for the tip on getting it to show with the build number and tapping repeatedly. Now I'll see if I can root this damn thing.

Open the app and click the top left of app (looks like a phone in front of a sphere) Select Tools>Root Explorer (turn ON) - Press and hold the word Root Explorer for 5 seconds - another screen opens. Select "Mount R/W" and select RW for "Path" and "system" - click OK
Press the top left option you clicked earlier (phone in front of sphere): Now scroll to the top and select Local>Device>system>lib>egl - Find the file named libGLES_android.so
Long press on the file to select it. On the bottom select "Rename" - simply change it from libGLES_android.so to libGLES_android.bak
Long press on the file one more time to select it. On the bottom select "More" and then "Move to"
Select the 1st option (there should only be two, the first one looks like a phone and the second one looks like an SD card), then select "system" and finally click OK
*Note: Doing the above steps increased the frame rates in Quadrant 3D benchmark scores thusly increasing the overall 3D score. I've done this simple tweak on this Ematic, my Viewsonic G-tablet, my rooted and ROM'ed LG Optimus S and it increased the 3d scores on all of them.
I've done more tweaking than what I've listed here but I hope this little bit helps

I could not get recovery to recognize zip file on ext sd so I copied it to internal drive and it worked great.
It is a bit tricky navigating the recovery window with the Ematic EGQ307 since there are no hardware buttons. Without pressing down too hard you scroll down the page until your selected option is highlighted and then push the Power button.
Help
Don't mean to revive an old thread but I've been searching and can't seem to find a copy of the stock rom for this tablet. Can anyone upload a copy somewhere? I managed to get mine in a bootloop, did a factory reset, flashed a zip to undo the mods I did and nothing. Regretfully I didn't make a backup. Hopefully someone out there still has this tablet and can help me out.
I liked this tablet so much that I got 3 more on sale from Walmart- another one for me and 2 for friends. After rooting them I've been experimenting with SetCPU and Juice Defender to see which one is more stable while extending the battery life. I don't think that I've gone a day without having at least one of them freeze up on me. No problem- just power it off and back on, and I can get right back to where I was before it froze. (BTW the freezing up is so common that the manual even mentions it as though it is a normal condition.)
Last week I had one freeze up for good and I have not been able to get it to boot up; it stays on the screen that says "ematic" with the 4 dots going from the left to the right until the battery goes dead. I tried the reset button, I tried connecting the USB cord to a computer. It had been running fairly well for a few days and then it didn't want to reboot. After hitting the reset button I was able to get back to the original sign in screen but it froze up again after that for good.
This one is going back for a refund but I was wondering what could be done if another one locks up like this later. Is there a way to boot the this up with an SD card or through the USB cable so that a stock ROM could be reinstalled if and when one becomes available.
One more question: are there any other tablets which are like brothers, cousins or twins to the EGQ307? Here are the numbers from the About Tablet screen:
Firmware version:
3.2_20130704
Kernel version:
3.3.0

P.S. These are really slick tablets for the price (~$80) and any further development for them would be great. Ematic has listed another 7" quad-core tablet (the EQS307) with a retail price of $250 and I have a hunch that it is basically the same as the EGQ307 but with more stable firmware and software.
EDIT: It looks like the problem with my tablet freezing up had to with the default settings in SetCPU... 1200mhz maximum/120mhz minimum. I raised the minimum to 456mhz and it hardly ever locks up anymore. (I had tried Juice Defender Ultimate instead of SetCPU and it had the same 120mhz default minimum value.)
I just got a Hisense Sero 7 Pro which is a much better low-cost quad core tablet and has a lot of independent developers working on it (Hisense released the source code for it in February but with the 7 Pro being a discontinued item I think that the developers are backing off a bit.) Newegg is selling factory refurbished tablets for $89.99. However I really do like the smaller size and lighter weight of the EGQ307 which Walmart has been selling for $59.99. And it does have a 16:9 display which is better for watching newer videos.
How to remove cover from EGQ307- easy as π
It is easy to pry off the back of the EGQ307 using a tiny non-metallic pry "bar" and starting right at the SD card slot. I believe that the one long wire going from the pcb to the bottom of tbe screen is the wifi antenna; if you are having signal problems you might try raising the wire a little bit (it seemed to help for me.) The battery looks very generic- which is good because it should be easy to find replacements that fit- possibly one with a higher capacity (just a quess.)
different recovery?
can i install a touch recovery on the ematic egq307 i cant navigate current stock recovery no vol buttons
just picked up 2 of these from wal-mart for $39 each, not bad at all for the price!
gonna see if i can get one setup & sent to my grandmother :good:
I just picked up mine from Walmart as well. Overall, pretty zippy for the price. The viewing angle is terrible and the memory/partition layout is questionable, but overall i think its going to be a fun $40 gadget.
Root was easy following the directions above. I recommend that you install TiBackup and uninstall the extra apps that you wont use, these run out of main space really quickly the way they have it configured.
If anyone has luck with a custom recovery, please share!
Hey guys, how did you get them for $39? Was it an instore only price? Online it is $49.99 and I am definitely noodeling picking up a couple of these for xmas presents.
I am thinking Link2SD will be a must have for these tablets once rooted. That should allow for lots of app/storage space.
Root Achieved for this Tablet model
First Download drivers for your tablet . A search online will bring up a generic driver . Though using Windows 10 you should not need to .
Windows has drivers that should work and install upon connecting the device .
Second . Go download Wondershare Mobile
Download the wondershare program for windows . It has a 5 day free trial and believe me you will understand it is well worth having .
Using the program after install go into the right hand column and click on Root . Then let it go through the process . It will describe the device as
something other than the Ematic tablet . Thats fine . Let it work . It will end up rebooting your device about 7-9 times and optimizing apps etc ....
Eventually after about an hour or so it will finish optimizing and it will come up with a Success message . You can disconnect your tablet and you can
either keep the program or uninstall it . I myself uninstalled it because I use Android SDK Studio for all my needs .
Success ... device is now rooted . You can now download apps that require root . As Ematic only gives a 90 day warranty it should not be any warranty issues
as most likely it is out of warranty anyway .
Now the cons -
If you did the rooting process to be able to move apps to the SD card then you are out of luck . I am guessing that Ematic has disabled moving apps
to SD card at the hardware level as even after rooting the device I was unable to get the apps to move .
Bottom line is that this process is the only easy process I have found to let you gain Root on the Ematic EGQ223BL tablet . Unknown whether it works on
other Ematic tablets or not . The tablet that was rooted was the above model number running stock Android 5.1.1 Lollipop .
Cheers
