hp6828 wm6 rom problems summary and report - iPAQ rw6828, XDA Atom Software Upgrading

The newly available 6828 wm6 rom is exciting but not without several problems. Here lists some and please report more in hope of the better rom.
1. The wi-fi do not trigger the blue LED.
2. The camera flash light do not work but the self diagnosis can turn it on.
3. The bluetooth headset do not work well. The headset profile works but a2dp do not have sound.
4. The cpu clock frequency is 520 not 416 which makes the power consumption higher.
5. The device will randomly halt especially when using ie or opera mobile to browser internet. The screen will blackout and press power button can reset the device.
6. The wi-fi sometimes will wrongly reported on while it is off after reset.
7. In hard reset screen, the buttons are wrongly mapped. press two soft key to continue it.
8. The esmertec jbed 20070802.2.1 do not have any certificates which makes gmail 1.5 stops working. The default java joede do not support jsr 184.
9. The green LED is blinking much slower. not really a problem.

One more problem is "it cannot unlock all softkey (left, right, call, end call, record, photo and volumn adjust)" without pressing power on before.
If anyone knows how to fix this, pls. share. I really want to use others button without pressing power on before. Thanks

Correct me if i'm wrong - But I think that it only appears to be running at 520Mhz due to fact the ROM came from an Atom Exec (which has basically the same CPU, just clocked higher)
Are you saying that the battery life on the 6828 with WM6 is considerably shorter than that of WM5?

Yes It really runs in 520MHZ with dynamic scale to 416 312 208 104MHZ according to the loads, several cpu overclock tools reports it and it is really faster. I say the power consumption is higher in my test. Before upgrade, I can listen to music using wm for about 3.5 hours but in this wm6 rom I can only do for about 2.5 hours in the case that the battery level drops from 100 to 0(my battery is severely deteriorated).
one more problem:
11. When turned off and reset the device, the screen will rippled but after turn off then on, the screen will be normal.

Did you install Power Management?
I think there are no problems with the power.

sorry for the inaccurate data. i forgot to close adobe reader which takes about 70% cpu when listening to music. now i tested it again, it lasts for about 3 hours and 10 min. i have installed power management patch.

modem link not show access point.
imsi not real.

i've install the power management things
same clock as o2 atom(520mhz)
but battery usage much less than orginal 6828 (stay longer)

ilovemeow too ..Gold!

the standby time may be longer (i didnt notice much difference),because maybe the LED flashes less frequent. but the actual usage time will be a little less, i just test the music playing. the current output resorted by some software is about 20 to 40mA more than the wm5 rom(the quiescent current is about 80 to 130mA)

.
Equaliser no effect in sound but adjustable.

TProfiler

First of all, thank you for your interest and feedback! Mostly due to your request I want to present you a new version.
Version 1.25 changelog:
1. Added Connections on/off
2. Added alarm - poor one
Version 1.20 changelog:
1. Added new profiles: WiFi on/off, Bluetooth (BT) on/off, Phone on/off. Added also Soft Reset.
2. Some minor changes.
Version 1.10 changelog:
1. Added half-hours (I think quarters are too much).
2. Hour format (24 or 12) is automatically changed depending on your regional settings.
3. I don't have VGA device, but I think now the screen is squeezed a bit so it can fit to VGA square screen. Please, try and tell me what happens.
4. Added sound profiles - low, medium, high and very high.
5. Number of settings increased from 4 to 15.
Please, download TProfiler120.CAB for latest version.
Automatically switches device sound mode(available profiles - sounds on, sounds off, vibrate, volume low, medium, high, too high), turns on/off wifi, bluetooth, phone mode and soft resets at selected hour and weekday and thus saves your battery power. Simple application, doesn't occupy memory. Tested only on HTC HD2 but should work on other devices too (TP2, Touch HD/Blackstone - tested thanks to replies to this thread).
It works fine on TP2
Great application.
It would be great if it had also a 24-hour mode .
It would also be great if we could set the device to change to a certain volume on the Ring and System. I like to turn my phone down to 2 notches on both of those and crank it back after 5pm.

+1 on this request.
Would be also great if one could change profile on headset plug-in/plug-out.
When I softreset the phone it gives me a non signed error.
VGA please

looks very promising as of this is really important to have because i tend to forget to switch my phone to silent when im at school
ill be watching this thread
Great application !
Feature request: time in quarter/half hours too.
You might want to add some additional 'rules'. If you have a different time schedule for every day in the week, 4 just aren't enough...
Awesome
Been waiting for a free app like this. The Connective Tools one is nice, but I love the continuing user driven development of XDA. The suggestions on here are great and I echo the setting the volume to a custom level and the quarter/half hours things.

+1 though 5 min time slots would be better. Are going to try and integrate the App so it will switch on calendar appointments?
just installed 1.10 on my HD, but when I start the app it alerts "Doesn't exist", and after tapping 'ok' the app doesn't respond anymore, actually the complete screen doesn't respond. Using the hardwarebuttons I can go back to my homescreen and then using the system taskmanager I can shut the app down after that everythings fine..
anybody got an idea? because it looks like a useful app to me
Dear Xsite3,
I think you had to wait for a while - when started first time the application takes more time (1-2 minutes).
Just installed v1.1 on my HD2 and i get the message attached. Any ideas?
When I try to start up TProfiler I get a message box that simply says "Doesn't Exist". After that I can click on the TProfiler icon all day long but nothing happens. Wonder what doesn't exist?
V 1.10 crashes for me
I was using version 1.00 with no problems on my HTC Fuze running WM 6.5. But version 1.10 crashes on startup with this error:
TProfiler.exe
InvalidCastException

Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger()

The app appears to draw at least a portion of it's window, and then crashes, though it goes by too quickly to see just how much of it is drawn
I really like the app. I especially like the addition of half hours in this version, if I can get it to work.

Fellows, sorry for keeping you waiting - Please, try now - it should work.

[TIPS - UPDATED 14/06/11!] Improve your battery life!

Turn off 3G, turn on only when needed
Settings -> Location -> Untick ''Wireless Networks and GPS Satelites''
Settings ->Accounts -> Untick Background data (Unless you want to use market)
Settings -> Wirelless -> Advanced -> Wifi sleep policy -> Never
Use phone on 2G, unless using internet (then switch to 3G mode)
Data traffic always OFF (Use only when needed)
Backlight low or Auto Brightness (And allow light to decrease)
Turn off wireless, basically everything turned off with the power control widget, turn on when necessary
Install task manager and set auto-kill mode to crazy on switch off screen mode (Put apps that always run in ignore list e.g. Launcher, Messaging. Basically the necessities)
Install SetCPU (After rooting your phone) - Min CPU 122mhz, Max CPU ~700mhz - 'On demand' profile
SetCpu - Profiles -> Screen Off -> Min 122mhz, Max 122mhz, Performance mode
Upgrade to Froyo 2.2 - Enable JIT (Saves battery on 2.2+)
Switch to a Cyanogenmod Rom
Enable undervolting (Only for CyanogenMOD roms)
Use RenderFX widget (CyanogenMOD, best to use low red, best to use when you are heading out)
Cyanogenmod - Spare Parts -> End Button Behaviour -> Go to sleep
LAST, but NOT LEAST, if you notice no significant increase in battery life, then your battery is no calibrated right! So go to market, download 'Battery Calibration', and charge your phone to 100%. Next, if its abbout 4000v - 4200v, your phone is correctly calibrated!
If its not 4000 -4200, press the ''calibrate'' button, and let your phone die out, then fully charge it (while its still powered off). Wait till light is green, TURN ON.
After boot, battery will not be 100% yet, reboot once more, charge to 100% (while phone is on), and check your new calibrated battery! It should now be 4000 to 4200v
I know there might be programs and applications to increase your battery life, but I dont have any experience with these, so feel free to post your experiences! Some examples may include juicedefender, etc
Anyone wants to add to this list, feel free =)

I don't know what goes wrong, but mine losts for only one day. If i have charged it overnight the battery is empty the next evening
No task managers. The phone manages its RAM well and the battery will last longer. For normal uses upto 1.5 days and for heavy users 1 day.

and here I heard installing juicedefender does more damage than good too.. what to believe? Everything is based on peoples hearsay and no evidence..
On my girl friends X10 mini I changed from ADW launcher to Helixlauncher and changed the brightness to auto. That made a HUGE difference.
Was on vacation and turned off 3G because I was not gonna use any expenisve data. That alone boosted my batterylife about 1 days worth.

people can do much to boost battery time, like turn off 3g, brightness control, turn off gps and so on, that all helps the battery
I have switched of almost everything and still get about 1 day of battery with about 2-3Hrs of music and a few calls and videos.
is it ok?
I get over 48 hours and I use the wifi a lot and do about 30mins of calls a day.
My tips:
* turn background data off and manually update ur emails when u want - this is the best tip I put it on my blog too
* manually enable network data when u need it
* use the top button to go on standby as soon as you are done using the phone
* keep gps, 3g and wifi off unless u want to use it
Sent from my U20i using XDA App
I have background data off.
No emailing whatsoever till now....
Almost 75% of the time in standby
Gps 3G wifi bluetooth are off.
Yet with stock launcer i get 24Hrs
Helix 30Hrs..
Why?
Its been two weeks(or 3) since i bought the phone...
Please reply.
BTW when did you buy the phone?
^^Ok.
I have come to know the problem.
Running any apps in background like Battery Indicator or task manager brings down the battery so much(the latter not much though)..
Because daily i used to get the above with battery indicator pro on.
But after uninstalling it i got about double that battery life..
So people better don't run them all the time.
task manager can be used sometimes about once every 2 hrs o so.
This increased my battery life so much on stock launcher
Just got the pro today. Will be ditching my X2 depending on the performance of this one after a week. So far, I love the mini pro for the fact that I can now hear my incoming messages and calls!
A couple of questions though:
1) Is there a way to wake up the screen when an SMS arrives?
2) Custom ringtone per contact?
3) Is there a way to disable screen lock when the phone goes to sleep by itself (not pressing the power button) ?
4) Is there a way to unlock the screen without the need to press the left button, I was hoping to go directly to the pattern unlock after i turn on the phone
Still getting used to the keyboard lay-out as I've been using X2 for almost 6 months.

I use Chomp SMS app and this allows the screen to wake-up, I think Handcent SMS does too. I never used the stock SMS app so not sure if there is a way to do it with that.

Not sure if this answers your question, I just press the Menu button twice to unlock the phone, never used the power button to wake it up funnily enough, only used the power button go in to sleep mode. When I press Menu button it wakes up to the pattern unlock.

Nice, i'll try to look for those apps. I did try the menu button and it worked. At least this relieves stress on the power button since I won't be using it to wake-up the phone anymore.
How's about not locking the phone when it goes to sleep? Unless I press the power button?
After a day with it, battery is now @ 30%+. Hope it improves or SE comes out with a high capacity.
Hi, where is the disable 3G button?
I can't seem to find it. I found wifi on and off.
and I unchecked location with gps.
thanks
Helix launcher is the best thing I installed to my mini pro. Batt life is now 3-4 days regular use and 5 days if i don't play games. Games are draining the batt quickly.
I'm totally getting rid of my X2.
3 to 4 days? Lol how can that be possible.. Did you use 3g?

I can prove it, there's a display in the phone where it says # of hours unplugged. If it's not working for you, doesn't mean it shouldn't for others as well. If you barely make 2 days, then that's what we should be LOLing about.
My setting is as follows:
- 2g only
- 1 to 2 hours of wifi and bluetooth per day
- 1 to 2 hours of games (love the games) per day
- tried GPS for 1 hour using mapdroyd
- a couple of calls and text messages per day
- tried watching a movie (AVI) for an hour using yxflash
- tried the media, played MP3s for an hour
- tried meebo for an hour
- I got my alarms ON always
- notifications ON always
- custom led lights for new SMS (using ringo pro) always
- max volume for the entire day
- medium volume at night
- data connection off
- background data off
- screen brightness to zero but the sensor is still working (weird), the screens still adjusts to the surrounding
This is after installing helix. Before helix, I got a max of 1 and a half days only.

Im finding the same issue. Im looking for the "use only 2g" as found on the g1 (my other phone) but I can find it. Some help would be excellent on locating this option!!

[UPDATED 24.12.10] TG01 battery life - an experiment, an observation

Update on 24.12.10 - My phone hasn't frozen or switched off on it's own since I made these changes! The battery life constantly stays real good. I have only charged my battery up to 100% TWICE in 4 days!! I think this trick works! I will really appreciate if more testers come forward and help us test this
What will this mean?
This will mean that we can make TG01 battery stay minimum of 24 hours and maximum upto 38-40 hours with good amount of browsing, calls, texts, games, ALSO keep exchange sync on forever!!
In total before my battery completely died, I was able to do the following:
2357 minutes of stand-by (includes the activities as well)
137 minutes of browsing
3 Downloads (total less than 10MB)
180 minutes of calls
36 text messages
21 email downloads using Exchange sync - that was ON all the time
60 minutes of gaming
18 pictures taken using camera
12 minute video recorded using camera
1 round of back up and virus scan
This is what I've done:
Installed SPB Shell here
Removed Taskbar (was a cab file in miROM4 that I am using)
Removed Start Menu (I have attached cab that I used to remove start menu)
Before you remove start menu or taskbar - PLEASE make sure you have full functioning SPB Shell installed. You will loose WinMo start menu and notifications (see attached pic) so you will rely solely on SPB Shell ONLY
On miROM4 by removing start menu and taskbar the original free RAM (96MB) increases upto 105+MB - I don't know how, I don't know why. This is my observation and testing!When you install SPB Shell, you will notice the RAM going down to 78-80MB on boot. - I don't think it's bad either.
Now you might wonder what's so different.
Someone did an experiment showing that by running apps the battery drain was 20% compared to stock ROM
Another experiment also led to show that battery drain mostly is not a ROM issue
I am no tech, I am no expert. This is my pure observation and my experimentation with TG01. I know the links I've quoted are for HTC mainly, but I suppose theory still stays. If any one is willing to replicate those experiments on their TG01 please feel free to collaborate with me.
I have updated all my uses on TG01 between 100% battery and 0% battery.
After 100% charging the battery,
Just to re-fresh what I have done with it apart from leaving it on 'stand-by'
I am running SPB Shell with it.
Using Opera 10 browser for facebook, bing, google (approx browsing 97 minutes till now)
I have read news on Evening standard and BBC (approx time 35 minutes till now)
I have downloaded recipe for 2 cocktails
I have made 6 (appox. 147 minutes in total) phone calls
I have sent 31 text messages
My active sync is on since 10pm as I have set my exchange email retrieval 'as item arrives' - so it has downloaded 14 email items at different times. Experiments have shown that results are quite bad when it comes to using Exchange Active Sync schedule 'as item arrives'
I have played Sudoku (about an hour)
I have left my backlight at 70% (on SPB you have an option)
My battery life after 18 hours 30 minutes is 80% with free ram of 78-80% without any processes running i.e. on stand-by!!
1 call (33 minutes long)
5 text messages
2 games (56 minutes total) of puzzle
Facebook using Opera 10 (updated status, replied few messages, browsed mainly)
Downloaded tube map from a website using Opera 10
Took about 18 pictures using TG01
Cleaned RAM, Virus scanned and did an online back up.
After 27 hours 22 minutes - my battery life remaining is 50%
Made 0 phone calls, 0 texts
My active sync downloaded 7 emails
I checked XDA website for about 20 odd minutes using Opera 10
I used facebook for 10 minutes using Opera 10
I recorded a video of length 12 minutes
All this time my wifi and data connections were switched 'ON'
39 hours 17 minutes - my battery is 0% and my TG01 switched off!!
Putting all these links together, I think if ROMs don't affect the battery drain, but by removing these two elements if my phone survives in adverse conditions i.e. exchange email (shown above link) and running apps/games (shown above link) - then it had to be either of these two elements or settings behind them that drain our TG01's battery!
EDIT: Yes, Oly after removing taskbar, when we press on 'Start button' it freezes the mobile. We don't need to remove battery to get rid of the freeze. Just few seconds and it comes back to normal. But to avoid that occuring, I used the attached cab. That cab removes start menu from the face of my WinMo. PS: This cab is NOT my creation. I have found it on XDA. ALL the credit for this cab goes to NRGZ28 - this cab will prevent making RegEdits
THUMBNAILS' LEGENDS:
1) How the 'Today' screen looks without taskbar and Start Menu Icon
2) How the SPB Menu replaces my WinMo start menu
3) How the SPB Menu replaces my WinMo start menu
4) How the SPB Menu replaces my WinMo start menu
5) How the SPB Menu replaces my WinMo start menu
6) How the SPB home screen looks without taskbar

I had DarkNinja task bar pre installed as cab from miROM4 - I removed it. It sort of 'disables' the start menu, but after that I removed start menu using one of the 'remove start menu keep x button' cabs and then eventually even removed 'x' button most programs respond to <- key at bottom.
I could attach cabs if you want but basically removing taskbar will remove all your icons on top and just leave the clock - it makes SPB Shell look nicer as well!
It been 27 hours and 21 minutes as I type and my phone's battery is 50%. I am going to edit the amount of tasks I have done in these 27 hours.
Hey drupa2drupad! Nice thread! I'm using similiar methods to you, but my battery is still awful! what battery are you on? Im on the stock toshiba one... i have spb shell running, opera 9.7 for abt 10-15 minutes, and the battery is 90% and opera 9.7 is meant to be more friendly for the battery,,, i have also diasabled the start emnu... i have had this layout for many months now and cannot reach battery levels as good as yours!

Hi Oly,
I am using stock toshiba as well - the one that came with my phone.
Did you remove the taskbar too? I am meaning to upload a screenshot of how my phone looks without taskbar. I am inclined to believe it's got something to do with removal of taskbar more than removing start menu. I have tried removing start menu on it's on and I had same result - Opera 10, draining 10% every 20 to 30 minutes of browsing.
I had desire taskbar installed as cab, I removed it! I am going to get some screen shots in first post
Hi Drupad,
Nice thread!! One thing I noticed was that disabling the start menu also gives 15-20mb free ram and it significantly improves battery life, disabling the sleep mode led and turning on wifi when not needed also helps!
P.S: After disabling windows start menu, I overided it with SPB Menu which is now my default Start Menu!

Hmmmm... I wonder how the taskbar removal makes a big impact on the battery life! I can understand the start menu, basically all your icons in the start menu are cached into the ram, so removing it will consume less resources , more battery life etc etc. But how doesit work with the taskbar? Im using the stck taskbar on Mangosora's 6.5.3 build with spb shell + mobilesense.

Yes i did that too on ffboys 6.5 rom(spb menu for startmenu) unfortunately it does not work for 6.5.3
Drupad, im guessing when u use the phone now, pressing the start softkey freezez your device?
Use the reg tweak to make the start button disappear (like the HD Mini)
You can find it by searching on the forum,
'HD Mini Start Key disabler' (something like that)

Probably, the battery difference is due to the start menu alone and not the taskbar because he removed both.

Nice thread!! One thing I noticed was that disabling the start menu also gives 15-20mb free ram and it significantly improves battery life, disabling the sleep mode led and turning on wifi when not needed also helps!
P.S: After disabling windows start menu, I overided it with SPB Menu which is now my default Start Menu!

Thanks!! I liked what I was experimenting and I thought more than 1 person analyzing what all these means, obviously made more sense
Yeah even Oly suggested he had free RAM (15MB) on disabling start menu so am sure about RAM now. I did use Wifi most of the time as well as data connection when I used Opera 10 for browsing. Did not disconnect data connection because it reconnected immediately - reason being my exchange sync set to 'retrieve as item arrives'
My start menu is SPB Menu as well Looks cooler, non-WinMo sort as well

Hmmmm... I wonder how the taskbar removal makes a big impact on the battery life! I can understand the start menu, basically all your icons in the start menu are cached into the ram, so removing it will consume less resources , more battery life etc etc. But how doesit work with the taskbar? Im using the stck taskbar on Mangosora's 6.5.3 build with spb shell + mobilesense.
Nice thread

I don't know if taskbar has got much to do with battery, but I did see quite a few reg-entries i.e. magnification etc - do they relate to taskbar? By removing taskbar, do I essentially switch these flickers off? Do you think anything i.e. notifications etc are being cached in ram as well? (non-educated guess!)
olyloh6696 said:
Yes i did that too on ffboys 6.5 rom(spb menu for startmenu) unfortunately it does not work for 6.5.3
Drupad, im guessing when u use the phone now, pressing the start softkey freezez your device?
Use the reg tweak to make the start button disappear (like the HD Mini)
You can find it by searching on the forum,
'HD Mini Start Key disabler' (something like that)

I have attached the cab in first post - this is the one I used to get rid of 'start' button completely. Yes my phone did freeze for few seconds to upto a minute, but came back to normal as soon as my screen locked! But after this cab, no problem at all! I think you can definitely have SPB menu as start menu - as it has got everything you need! I have 6.5.3 miROM4 as well and I was able to do it and use it flawlessly. I will try to put some more screenshots

I agree it has to be start menu but don't know if it's alone because Oly has disabled start menu for quite a few months now and he din't seem to notice this drastic change :s
If you guys see any changes by removing taskbar (if you are going to ) then please post back, may be we could be improving our battery lives

hi drupad! sorry i had a typo in my other post... i was meant to say i can sucessfully disable the start menu on 6.5.3/6.5.5 , but i cannot get it to open up the spb menu in the spb settings. there is no option for it... i will try and post screenshots soon! also i have been using this technique for months and having noticed a battery performance increase because i thought it was to do with the ROM i changed from ... i guess it does make a big difference! i will try and disable my task bar and report back! im not to sure if disabling the task bar stops your notifications caching in the RAM. perhaps someone else could help us out?
hi drupad ! just reading through your first post again, the guy who created the cab is NRGZ28. he is one of the most respected members of XDA! he creates his energy rom series for like all htc devices and updates them all once a week!

Thanks a lot for that mate will update first post tonight when I reach home! I wish more users could test this and give feedback.
I might have just made this battery issue 'not so severe' any more with these observations!!
Another thing I just realized is I haven't restarted my phone at all - The last time I switched off my phone was when I completely ran out of battery during this 'experiment'!
My phone seems to have stopped freezing. Its 4th day now!!

Hi.
I do not belive in miracles in electricty area but decided to sacrifice myself and test miROM4. I remove wm start by mirolg .cab "miROM_MMLauncher_Mod_Startmenu_Replacement.cab" and removed "Dark NInja Android xxxxxx". I did only "natural" test so far, by configuring SPB for my purposes
what took several minutes of time and battery has lost 20% . ( in my appinion quite normal for 1000mAh battery because of backlight was still on and few minutes of GPRS and Wi-Fi was done and this is what I observed on any ROM I tested so far).
Anyway, now I am charging battery to 100% and will do some more tests.
What annoy me after removing task bar is that I have not any information whether I have active GPRS or Wi-Fi connection and I have not any speed mechanism to disconnect ( what could be done very simply via notification bar). Have You got any idea what to with it ? Maybe SPB has any widget for it ?

Hi fxdjacentyfxd
I din't really look into monitoring speed of connections. I used widgets to mIake sure how much battery I have, if I am connected to wifi or not. When I was connected to data connection - I just checked if I am connected or not by using 'Connections' in the settings.
I am keeping my backlight at 30% now most of the time. I have seen even 10% makes it better, but my eyes don't really like that dark so I keep it 30%. May be that will help as well?
I have used it this way since - and also changed to miROM10 now, and still don't charge my battery at least before 30 hours of use! - which I find to be good battery life for daily smart phone use
Good luck and thanks for trying this, will wait for your feedback

Some software are able to connect via GPRS automatically and disconnect too after exit ( Palringo ) but most of them not. So I would like to have such fast way to disconnect ( I did not check - battery is still charging in shutdown - but mentioned "Connections" have not ability to disconnect from GPRS ?. As I remember there are three fields Phone, BT and W-Fi. Wi-Fi shows connected or not and one can switch-off wi-fi . It is not the same as as disconnect but better this than nothing.
Phone only shows that whole GSM radio is on not GPRS connection.
Anyway, maybe You know any kind of software that allows to manage GPRS-Wi-Fi. It does not has to be in upper bar. It is enough I will put it on SPB window.

Yes in my oppinion ( I was dealing with other "small" devices like PNA and PDA ) backlight is factor thar can dramatically make battery live longer. No wonder , it requires a lot of energy.
I guess that You ensured very good conditions for Your experiemnts. I mean very good quality of GSM and Wi-Fi signal which may cause the transcievers on tg01 could work with low power. It is in my oppinion second main factor. In bad conditions GSM can "eats" even 1-2 W of power.

Do You want to say that with miROM10 You have the same good result as with miROM4 without removing task bar and wm menu ?
Recently I tested miROM11 ( as mirolg said there are only minor changes in comparison to miROM10 ) but I am rather disappointed. Not stable. Eats battery as any other ROM.

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.

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 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.

Increase your battery life and.......

I made a lot of experiments trying to squeeze most of my GT-I8552 battery & RAM, and finally I reached those results by the below strategy (please note that this will be just strategy/tips, not detailed steps), and on ROOTED STOCK ROM It currently gives me:
1) Average Screen Off Discharging Speed 0.3-0.5%\hour (so battery needs 200 hours to discharge, or more than a week!)
2) Average Screen On Discharging Speed Between 10%-20%\hour (no Gaming) (so working hours about 8-7 hours)
3) Free RAM after full startup 65%.
(I gathered those statistics by setting Tasker to calculate them for me).
Battery Tips:
So to see almost a perfectly horizontal line of your battery discharge during your sleeping, you will need:
1) Rooted Stock ROM (I tried this on KitKat latest version).
2) Greenify.
3) Tasker
4) Your brain and some work.
OK to get most of the battery, do the following:
Remove all LG & Google Bloat ware; search XDA how to do that.
Disable all animations in you Settings-> Accessibility, this will save our battery and make apps faster.
Now all of the work should be done in Tasker, I assume that you already know how to work in this thing, if not search XDA there is a lot of tutorials...
Once your screen is off, do the following in Tasker:
Turn off the following : WIFI, Bluetooth, GPS, Auto Sync.
Greenify all bad behaving apps, after that use tasker to force close many of the bad behaved one (you should experiment with this).
Down Clock your CPU, for some reason my device reboots unless I set Governor to conservative or onDeman, so here we put it on conservative, with CPU clock between 300 and 652 MHz, there is no need to make it lower, because it gives no better battery life, and it makes wake up time longer.
Those steps are enough to make sure that you will lose about 0.5% per hour only! (my CPU needs about 5-10 minutes to enter deepsleep, this means that your battery drain during this time will more than 0.5%)
On screen ON, you need to immediately set back your CPU to onDemand mode, otherwise it will lag, actually I made 3 profiles for CPU, low (during screen of), medium (when screen on), and high (during gaming), so here I set the OnDemand with frequency 300-1190 MHz, and you will not notice any lag with those settings, also you need to set the maximum priority for the Tasker profile that will do this, well actually I made my own Lock Screen by Tasker screen so that tasker will stay foreground app and has best CPU priority, so swapping CPU profiles will be quite fast and you will see no Lag.
Also I set a periodic sync, when screen off each hour my phone wake ups and turning on wifi (or 3G if I’m out) and turning on AutoSync for couple minutes, and then turn all those things again to enter DeepSleep (step 1).
you need to make a good Screen brightness management in Tasker, there is tutorials on line for that.
Finally, during working, I set many specialized profiles for different apps I use a lot, for example, you don't need AutoSync when you are talking by phone, or reading a book, also when reading books, you don't need high CPU frequency, so I lowering it down, all this tweaks needs some work, but anyway you it will give you considerable battery gain, and you will see that the application that you really using a lot are not more than 10 apps.
I would like to note that I tried many ways to optimize this (except trying different ROMs) like playing with application's wake locks, but nothing worked as good as this strategy for me, if you have some more suggestions it will be great.

Many of us trying to make our phones customized and more beautiful, but after a lot of tries I found that all those things only making things worse, even for a monster like LG G2: I tried almost 99% of Launchers available on store, and all of them are very bad in scene of resource usage, for example the most beloved Go Launcher, having 200+ apps, and 3 pages of widgets, uses about 150 Mb. of RAM, this is too much, considering that android itself using about 200Mb. in worst scenarios, even the launchers that claims to be very efficient like Lightning & ssLauncher, that is not true, because once you install them, they indeed use too little at the beginning, but once you customize them and will add widgets, objects to them, they will jump up to 100Mb., well this still is better anyway than Go Launcher.
So to be short, the best one in terms of memory usage, is definitely, and without any competition, is Smart Launcher, it seems that it has a unique possibility to draw/load the widgets on demand (you can add them on special pages) and once you go back to main screen, it will free up used memory in minutes, that's really great, because this launcher on average uses only 50Mb. whatever the widgets you use!!
Also I would like to note that most Lock screens are very memory hungry, I tried lot of them, and none of them used less than 40Mb.!! so it almost like a second launcher! even the best of them like widget Locker or C-Locker! that why I made my own by Tasker itself, but note that after designing a scene in Tasker, it will use a lot of memory (70-80Mb.), and for some reason doesn’t free it unless you restart Tasker, and fortunately after that it will use not more than 20-30Mb. even when the scene is visible! so considering other things Tasker is doing, it's pretty low! so I highly recommend this.
Also any programs like recent app's viewers, side bars, screen buttons etc.. are also very memory hungry, I tried a lot and none of them really efficient, don't dream to get one with less of 50Mb. usage! so it's better, in my tests, "on screen buttons" are the best one with about 10-15 Mb. usage in case you don't like the navigation bar as me))
Dear Axit,
Where did you get the stock kitkat rom for GT-I8552.
