I recently installed words with friends and have noticed a major drain on my battery caused by it slamming my cpu and RAM. All it is, is a scrabble type of game but continues to BASH my phone in the background. I have never experienced such drain from any game let alone a game that is not very graphic based. Something strange is happening here.
Has anybody else had the same issue? I don't remember it draining my battery as bad on my SGS 1.......

The problem is happening on my best mates iPhone too
Its probably the apps code. Its making the phone run both cores at Max for no reason.
If your a root user try underclocking to 800 and see if its still bad.

Change background notifications to never in the account setting page. Also force close it in the battery status screen.

Same thing happens to me. My phone gets so hot and my battery drains like crazy whenever I play the game. I wish the Developers would fix it, cause I love playing this game!
I use task killers (e.g., Advance Task Killer) to autokill the app when the phone is off, because sometimes the app still runs in the background. And whenever I turn my phone back on my battery is almost dead.
It's the problem with the app itself and until they fix the problem I'm keeping it away from my Android phone, that's lame.
Words is just a pain but my ios friends play it ...
What I do with mine is have a rooted phone and have tasker and have to cripple the phone to 500mhz max so it's still playable, just not speedy or it'll sit at 1000mhz looking at the game board but the waiting for moves screen can sit at 200mhz displaying ads
profile is words
entry
1. notify, "words running"
2. notify cancel, "words running"
3. cpu, gov powersave 500-500mhz
4. wait, 1second until %cpufreq < 510000
5. if, %cpufreq > 500000
6. goto 3
7. endif
8. cpu, gov conservative 200-500mhz
9. if, cpu > 500000
10. cpu powersave 500-500
11. endif
12. notify if %cpufreq < 510000, "throttled - max 500" with a icon of a hippo
exit
1. cpu gov, on demand 200-1200
2. notify cancel "throttled - max 500"
i also have a shortcut to task that launches words, just sets the gov to conservative 200-500 and loads words, the cpu freq won't stay at your max if it's already over the maximum
it loses smooth scrolling around the game board but uses half or less of the battery it did just running as is. when words isn't in the foreground it'll go back to whatever you set it to
Found this searching for my own issue. Just killing the app after closing it didn't help enough because it would still drain while I had it open.
Using the AT&T version I get the same issue. WordFeud's footprint is literally non-existant so I would suggest moving to that app. It's on iOS too.
I think they finally fixed it with the new words update

its a paid app so therefore i will not post any links. but there is some info about using it on the galaxy s devices and how we should avoid some settings and use others to dodge the bugs...
copy/pasted
Description:
SetCPU is a tool for changing the CPU settings (capable of overclock and underclock) on a rooted Motorola Droid, Nexus One, G1, G2, Samsung Galaxy S, or one of many other devices to improve performance or save battery.
SetCPU also allows you to set up profiles to change the CPU speed under certain conditions, such as when the phone is asleep or charging, when the battery level drops below a certain point, or when the phone's temperature is too high. See the screenshots for examples of how you might set up profiles.
SetCPU's wide feature set make it useful to beginners and enthusiasts alike. Accelerate your processor to unleash your phone's multitasking potential, or dial your CPU's speed down to save battery.
Have an HTC Sense device with a stock ROM or kernel? If you are having trouble getting your settings to "stick," press Menu > Disable Perflock. You still have to be rooted.
Galaxy S devices: ondemand scaling is recommended. There are issues with Galaxy S kernels that may result in crashes if conservative scaling governor is used, or if the sleep profile "max" value is set too low. Please do not set the sleep profile too low, and avoid using conservative scaling.
Requirements:
all Android versions
Recent changes:
2.1.0
- Significant UI and user experience revamp, including a new background for the widget, and new notification icons
- Added a quick priority swap button to the profile lists
- Significantly improved the reliability of autodetect on certain kernels
- Numerous bug fixes and crash fixes

I understand it's a paid app in the market. But if you're an XDA member you just go here:
http://forum.xda-developers.com/showthread.php?t=505419
It's not a secret...
Funny, the previous version of SetCPU specifically told Galaxy S users to use conservative scaling and that ondemand would cause crashes.
Now they're saying the reverse.
Edit: Well, I switched it to ondemand as the app dev suggested and the phone turned itself off a few minutes later...
Are we suppose to flash it thru cwr?

Do you have a profile for screen turn off? If you do disable it because the phone itself lowers the cpu while at sleep.
Sent from my SGH-T959 using XDA App
I have no profiles set. I tried doing the sleep profile but it caused some annoying lag when the phone was waking from sleep.
On demand profile settings do not work, my phone has crashed 2 times. SetCpu just doesn't work I guess.
Using Nero V 3 and set CPU isn't doing anything...max setting is set to 1000.
How did you guys get it to work and what are your settings?
Sent from my Galaxy S via XDA App
Those of us using SetCPU are using overclocking kernels. Some folks might be using DOW, but I am using JAC XMOD because I'm still on Eclair as all the 2.2 ROMs annoy me currently.
(At least until I get my Bionix Blackout for Nero v3 theme finished!)
So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.

I am rooted, thank you for the info! I'll be looking into it~
Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.

There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.
If I let my galaxy s3 run for a few days without rebooting sometimes it will idle at 50 degrees celcius. Then when I restart it goes back to idling at 35 degrees or so. I think it might be a application running in the background. I cleared all the active apps before I restarted it, but this was only the second time it had happened so I kinda panicked and just restarted it before checking anything out. Could it be SwiftKey or one of the other active applications. The temps are of the cpu not battery.

It might be the problem with the gsiff_daemon running away and using all of one CPU. When your phone is hot, go to Settings -> Developer options -> Show CPU usage. With that checked you will get an onscreen display of what processes are running, and a bar indicating how much CPU they are each using. If "gsiff_daemon" is at the top of the list, with a green and red bar, then it is the gsiff_daemon problem. Currently there is no solution other than to kill gsiff_daemon (I do it from the command line) or reboot. If it is not the gsiff_daemon problem, then hopefully Show CPU usage will let you see what other app or process is running hard.

Thanks, I think that it's Facebook running in the background. If I don't close Facebook its the number one process (com.facebook.katana) even if I'm browsing the Web. Even if I do disable notifications and close out of it its still the number one process while sitting on the home screen.
Edit: ol Facebook seems to have fallen off the process list. Using Facebook makes phone really hot(cpu can hit 50 degrees celcius). what could it be doing that would need that much processing power?
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.

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.

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.

Thanks, glad to know it's not just me and I don't have a real "ghost in the machine". I use my Nook on the train everyday, couple times a week I have to pull out an external battery to keep it going.

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.
RAM Tips:
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.
