ok m done with this battery and free ram issue, my battery life is draining so fast on any of the JB roms, its like 1% on 30sec screen on.
i turned back to try ics(criskelo v6) while the rom is great, i get also a good battery i guess, around 7hours screen on, 6 hours of videos and virtually unlimited standby time. the only cons here is that i have 704mb used out of 784mb , also i removed touchwiz, live wallpapers and some bloatwares.
note that checking battery life and ram usage is done with no apps installation, just on the default roms apps. no special app draining battery.
also, battery is taking over 4 hours to fully charge from 10%, even while the device is powered down and on ac charger.
on JB roms like (omega and criskello) battery is draining super fast and charge super slow, but i have over 250mb free rams, on the other side, on AOSP roms (paranoid) battery life is better than other samsung JB based roms, but i get only 100mb free rams.
ok i want to stick with ICS roms for now, seems like JB roms are not stable till now, but also i still have this free ram issue in any rom, any suggestion for this problem,
-is it a kernel problem?
-is it my battery problem?
Try searching for "free RAM" on the forum and read a few of the literally thousands of posts about it.
Short version; don't care about it. Android reports free RAM different from Windows and BSD-based systems (including OsX/iOS), so it confuses users.
Battery life is an issue with JB, true. It'sbetter with the new Siyahkernel but still completely random and not great.

I have a stock SGS2 with a lot of widgets running. I use BetterBatteryStats and have removed the high power usage apps.
Past few days, the phone uses a lot of battery at night. Yesterday it had 32% battery and when i woke up it was dead.
Are the rest of you also seeing this much battery consumption every night ?
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
I gave up with the stock S2. Rooted it and flashed MIUI to it along with the Siyah Kernel. Now it uses only 6% for the whole night. Battery usage is so much better now.
People having issues with battery should try the siyah kernel and change governors (unless some app was draining your battery)
yeah, actually some new users will experience battery problem. however, some says that when time goes by, the problem eventually sorted out itself.
i am guessing the phone need "warm up time"
I had the same problem with stock rom. you have to remove the preinstalled useless samsung apps. then battery consumption is better.
i am now on cm7. everything is working and around 8% per night with a lot of background processes (tasker, lbe, scheduled titanium backup).
Don't always turn on wifi or data unless necessary.Turn off background sync.This should help a lot even u r using stock rom.Kill tasks with built-in task manager.Make sure useless apps are not running in background.
With these tips,my s2 with rooted stock rom and stock kernel only consumed 3% of battery all night .
i keep wifi or gprs on for instant messaging needs. The Siyah kernel and the lulz governor give amazing battery life because process runs at lower clocks instead of jumping to 1200 unnecessarily.
The stock kernels aren't too bad in my experience.
I think you will find your battery drain will be caused by rogue apps before the kernel.
Edit: why have this phone if your going to turn off gsm and data etc. May aswel turn the phone right off and have zero drain overnight.
A drain of 1-3% per hour with everything turned on is normal for me.

Which rom gives the best battery life currently i am on stock 2.3.4 its battery life is wore charge drop from 100% to 60-50% in just few minutes and i would also like to know that why my internal memory was showing only 1.97gb total space when i unlocked the boootloader and installed CM7 ICS.
Now I have flashed the Stock sbf with rsd so i will have re unlock the bootloader which unlocking method i should follow bcoz the last the time i unlocked the phone i was facing some problem like
1 .No boot screen only text screen which was showing os will start in 5 sec and with other options.
2 .The model number changed from ME860 to MB860.
3. Total internal memory in CM ICS was showing only 1.97gb.
with normal use (texting, phone, small amount of games) in CM7 I get about a day. no mods, just the radio in the OP. With alien normal use I get around a 30-36 hours. Heavy use drops down to about 10 hours or so CM7 and 12-15 alien. the 1.97 is normal on CM7. not sure about the rest
my battery life on CM7 (both nightly 20 and ba2tf) is the best ever.
I have tried all of the roms and they all have descent battery life, but the stable CM7 is the best one for me. compared to other blur roms, it's by far the best. I can have my cellphone with 80% + battery life at the end of the day with minimal usage. With some moderate usage (texting and browsing mainly) I sometimes have around 50% charge at the end of the day. even while giving my phone a LOT of usage, I have never had battery problems while running those roms.
sometimes I don't even charge my phone if I only had some minimal usage through the day.

I agree: cm7 is the best. I have the last weekly from CM7 and have a battery live of 72h with minimal or 48h with normal usage.
Interesting... For awhile the wife was running CM7 at stock speeds and i was running DarkSide at 1500MHz. Even with a 50% overclock I consistently had better battery life compared to her, both using our phones about equally as often. When I get the time I'll be doing a more thorough evaluation between our phones with proper battery calibration, etc.

i think it depends which radio is installed. i got the best results with 1.77.36
i have installed some roms. when i install for the first time, battery time is good. but whenever charge my s3 for the second time battery drains faster.
Lastly, i installed ArchiDroid V1.7.15. Standby time was more than perfect. on avarage usage, 3,5 days
But after i charge it for the second time, battery drains faster
what is my fault?
Let the ROM settle. use what ROM you want. Charge it few times. It should pass like one week at least tohave a good view on how the battery performs.
Bloatware, apps, wallpapers, startup apps, backgrounds.. they will all consume power.

yes but i install the same apps and system each time
Are you on a cm or Touchwizz rom ?
Personally, my method for having a pretty good battery life is like this :
- After you flash your rom let the battery get empty and then charge it to the max without have it on, just plugged in.
- Repeat this method for at least 2 times and then you will get a good average of what the battery life looks like on this rom.
Keep in mind that each rom have different battery life, because of all the tweaks and optimizations that the developers add to it.
And also, don't forget that AOSP rom ( CyanogenMod, ParanoidRom, etc... ) are slightly less under the official samsung rom in terms of battery life. That's why a large number of people prefer official samsung rom instead of the AOSP one.
I think that everyone does have your problem actually
thank you
i am on ArchiDroid V1.7.15 rom
No problem
interesting, i did it 3 times
3,5 - 4 days standby time with medium usage
when i recharge from zero, it drops 85% in 4 hours, with very little usage
reformat, reinstall ArchiDroid V1.7.15 rom. and it is great again...
i do not understand anything
Maybe you can try this.

But I'm not sure this will work or not. Someone says this is just nothing but waste of time

i have tried it 3 days ago. anyway, thanks for your help
any other help?
I was thinking about moving over to a G3.
But from the reviews the battary life seems to be horrible on the phone.
Has that improved with the lollipop update? Or still about the same?
Thanks
I have zero issues with battery. Rooted and removed bloat and get all day into the next. Also I love greenify, with nova and a gesture to double tap to sleep and hibernate apps I get sick battery life.
Depending on lollipop. Running unofficial lollipop ive experienced between 5-7 hours of SOT. I've gotten up to 9 hours SOT on kitkat with battery saver apps. Try it out for a few days and see how it goes. Every phone doesn't respond to the same changes.
I've been absolutely impressed with the battery life in this device. Every once in a while, I'll have a day where it seems to drain faster than normal, but I'm sure it's a rogue app syncing. I get about 3.5hrs screen on time, and 17hrs off charger. Average. And it sleeps really well. When not in use, virtually no power drain. All of this is on custom ROMs. Can't speak to stock ROM, never ran it. Closest I've come is modified stock with root and with bloat removed.
Running stock lollipop now. The battery isn't anything special but its not horrible either. The standby time is very good.

Hi,
I'm trying to save my Samsung Galaxy S3.
I have to charge chinese golden 3000mA batteries every six hours.
After six months, batteries are completely wasted.
It's a battery eater... but I have no budget to buy an S7
Cheap phones have more or less the same features...
... and I love S3 cammera and its user replaceable battery (no more planned obsolecence, plz!)
It has installed Android 4.3, I9300XXUGNA8, kernel 3.0.31-2429075, compilation number JSS15J.I9300XXUGND5
After installing CM Launcher, and moving to Facebook Lite, the battery usage is:
screen 21%
android system 18%
android os 17%
google play services 8%
chrome 8%
gmail 3%
whatsapp 3%
waiting 3%
camera 360 3%
Also, sometimes when CPU is a little bit stressed its temperature raises.* You can feel through bottom zone of screen that it burns... could it be a hardware failure affecting battery consuption?
Any recommendation to have less battery consumption?
I'm open to change the ROM... or to install Ubuntu Touch if necessary
Thanks in advance
Buy this Luminous(LivGuard) Battery and I suggest you to try some custom roms and choose the best rom for you LiquidSmooth KK RESURRECTION REMIX LP RESSURRECTION REMIX MM with Boeffla Kernel Use greenify,Amplify and Disable services(To disable some useless running google play services permissions).
Screenshots from my S3. Rom- Liquid Smooth. Kernel-Boeffla
Hi Sureshtuty,
Thanks a lot for your response.
I'll try both the battery, ROMs and apps
I've read these days that Marshmallow comes with Doze mode to improve battery usage
http://forum.xda-developers.com/gal...t/rom-cyanogenmod-13-nightlies-i9300-t3272811
Do you think that could I save battery with Cyanogenmod-13 (Android 6)
Best regards
Are you sure yours battery have 3000mAh ? Screen use most of energy. Try reduce to 30. You tested other kernels or try this http://forum.xda-developers.com/and...ebf-tweaking-battery-saver-optimizer-t3401341 (most tweak in bulid.prop) ?
For now cm13 is not bad but not good.

Don't go for cm13, its battery hungry. If you want good battery backup use touchwiz ROMs or if you want mm then try haxynox(eats battery but less as compared to cm ROMs)
