Hi guys,
I am know on a stock rom and I hate mt phone because of my battery life. My battery is going to 50% when the clock hit 16:00, and I dont use the phone so much.
Which ROM with kernel can give me a boost for the battery? And ofcourse the phone must also be smooth
Thanks..
THE RULES.
All kinds of Best Rom/Kernel/etc threads are unwelcome, read, research and make your own mind up, as the question is very subjective.

We can't really tell you, you got to start reading and try it yourself. Because the way how we all use our phone is different.

Your bad battery life can be because of many things. If you have things like Facebook, Google+ auto syncing, constantly polling the internet for new data, that can certainly destroy your battery life. Push e-mail can also be a big battery thief. So start out by going through your settings for sync and disable everything for a day or two - just to test out if your battery life is better without apps auto-syncing.
A good tool for finding out about what is eating away your battery life is the app Better Battery Stats, find it here: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
The most interesting section in Better Battery Stats is usually "partial wakelocks". Install the app, charge your phone fully, unplug it and use it normally, letting Better Battery Stats collect data about your device. In the evening, check for "partial wakelocks since unplugged" and share screenshots of that window here on XDA.
This would be a good start for you! Let me know if I can do anything to help you further!

Hi, folks
These are tips for improving the battery life of your SGS2 :
1.Set the wallpaper , with dark or black images
Set the brightness to 10%
2.When you are not using data , please turn it off . Using 3G data will suck lots of juice !!
On the other hand Wifi doesn't suck so much juice
Now the next steps are the most important
3.Please do keep charging between very short intervals ,
Let the battery charge drop to 5-10% then charge till it reaches 100% , this will considerably , increase your battery life .
4.Do not let your phone keep charging for a very long time ,even after it reaches 100%.
This will damage the battery .
Actually when your phone shows that it has been fully charged (100%),it has only been charged for 95% , so plug in for a few more minutes ,for some extra juice .
5.Do not install lots and lots of unused and useless apps ,as they will not only occupy memory , but will also suck the juice out of your phone !!
6.Delete unused widgets from home screen
7.Close unwanted apps running in the background.
Go to task manager and press the ,'clear memory' button frequently .
8.Do not use the charger of other mobile phones , even if they have the same pin ,as this will slowly damage the battery
9.Use only original Samsung battery made for your SGS2 , duplicate or other battery will not only be waste of money , but will also damage your phone !!
10.Sugesstion are welcome , you can posted it , so that i can add it !!
11.If you know a few extra tips , please post it or PM me
12.If you like this tread please rate it !!
13.Please press the thanks button , if you like this post and if i helped increase the battery life of your SGS2
These things helped me improve the battery life of my SGS2 ,I hope it also help you considerably increase the battery life of your SGS2 too
Cheers ,

While I appreciate you giving advice to our members about battery life, you have some flaws in your tips

1.Set the wallpaper , with dark or black images
Use autobrightness or set the brightness to 10% <-- First you tell people to turn on autobrightness, then you tell people to turn it off and keep it at 10%. Which do you recommend? You can't suggest both. Also, autobrightness will drain your battery more.
4.Do not let your phone keep charging even after it reaches 100%.
This will damage the battery .
Actually when your phone shows that it has been fully charged (100%),it has only been charged for 95% , so plug in for a few more minutes ,for some extra juice . <-- Again, you're contradicting yourself. You're telling people not to charge passed 100% but then you tell them to charge passed 100% because you can get more juice? Pick one.
7.Close unwanted apps running in the background.
Go to task manager and press the ,'clear memory' button frequently .<-- You're wasting more battery by telling Android that you dont want those apps in memory because the OS will just add it back into memory (thus, using more battery to do so). This is only good if you have a rogue app that is killing the battery, otherwise just let the OS do its job.
9.Use only original Samsung battery made for your SGS2 , duplicate or other battery will not only be waste of money , but will also damage your phone !! <-- While I can't really speak for sure because I'm no expert but I'm pretty sure generic batteries will not kill your phone if they're designed for the phone. We have a lot of members that use generic batteries and their phones run just fine.

Lithium Ion batteries "prefer" short charges.
What's written is applicable to Nickel Cadmium batteries, where charging after partially draining the battery will reduce its capacity.

Where'd you get it? I bought a cheap extended one off ebay and it was great, but after about 3 months it was lasting as long as the stock battery.

My phone is experienceing severe battery drain whenever i use an app.
i tried switching between the leedroid v5.4 and nonsense 3.1 roms but both had the same problem anyone know a fix.
BTW i did not overclock

I noticed that my phone does that when I am in a weak service area. The radios use a lot of juice trying to get/keep a signal. You could try Better Battery Stats or Bad Ass Battery Monitor to see in more detail what is using your battery.

you can also try to calibrate your battery with serval apps! type in play store : battery calibration ! they all do the same job and preaty good i must say..
i recommend you to try : Battery Calibration free . thats for rooted users and does great job!
Alright Thanks
I sorta realised it was due to my connection as my school has a really bad reception and thats where teh majority ofteh drain occurred will download that app
My personal experience!!!!! Flame me not!!!!!!
Ok here goes:
I don't use any battery calibration apps or system tuner or task killer any more. I test my battery like I test my gas mileage: ALL THE FRIGGIN' TIME!
I've found I get better battery life without these extra apps. However, I also completely strip all ROM's I use of completely unnecessary apps and their respective widgets (HTC News, HTC News and Weather, Jetset Printer, Stocks, Twitter, Picasa, Google +, etc.)
Now, the only app I would recommend and have heard from multiple sources and threads is Better Battery Stats. It has a nominal fee, however, is worth it. I will show you what is draining your battery.
You could also have wake lock problems. Who knows? Get some diagnostic info to post to better help those trying to help you. Help me, to help you! LOL!

Flame on! Just kidding. I also have never calibrated my battery as it is useless according to the Android engineers at Google.
The reason I also recommend Bad Ass Battery Monitor is because it is a little more user friendly.
Also, there is an xda version of Better Battery Stats that is available in these forums for free, although the Market version is cheap and supports the dev.

i have some problem, when my screen active, i put it to my pocket, then my body touch the screen and do random process abaout 45minutes.. done with 40% battery gone x_X.. i think u must tell us how long u use app
You can use battery calibration. you can find it in the android market
Have you tried reset battery stats then full charge, use it for a couple of minutes then full charge again? Don't know why it works but I have used this method on a couple of Roms and it seems to help
try clearing your battery stats full charge ur battery n then let it discharge fully then full charge once more n recalibrate it..should work
The main factor for preventing battery drains is to have a good modem that doesn't overheats the phone, using a ROM with deep sleep and a battery friendly kennel like Siyah or Fluxxi. Try to get those three things fixed and you should not have any more battery drains
Turn auto brightness off also make sure none of your apps are using your GPS all the time. I think the problem may be app related I would roll to a stock kernel and only use apps that are must need and see if that helps. Also your battery could be shot . How old is it ?

hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
Hi there.
i need a help. i try a lot of battery saver app. none of them worked well for me. can u guyz suggest me for a better battery saver app.
Thanks
In my opinion, battery saver apps are more trouble then they are worth. Basically all they do is turn your data off. You can do that yourself.
Honestly battery saver app are more harmful than helpful. When I tried couple of them, they don't help much at all except the standby time. Just check if they phone goes into deep sleep or not. Switch wifi to off in standby. Turn off the sync if you don't need. Those basic method should help you out. There are a lot of good tips on this forum but if you must use battery saver app, juice defender is your best bet with some right setting.
Hi I have the pacman jb rom 4.1.2 works great just battery I notice don't last long or I am not doing something wrong. Are there any ROMs that have good battery saving or great battery life?
Sent from my Evo 3D CDMA using xda app-developers app
Battery life on ROMs depends on a lot of things!
For one, how much you use your phone! If you're on it all day playing games, watching youtube videos, syncing facebook and making phones calls....you can't except it to last too long!
Here's a few things that could help you improve your battery life.
For one, turn off auto brightness and adjust it to something that's good for you in the room or environment you're in.
Apps like Facebook, Instagram, Twitter and pretty much any social network app that syncs contacts, feeds and things like that are battery hogs! Turn your auto sync for these apps off! Only sync when you need to and just be smart about that kind of stuff.
NOW you have the kernel! You need to give this some time to settle in to really judge your battery life! What I do is let the ROM cycle about 2-3 times from full to empty before judging the battery life! If you flash a ROM, chances are that the battery life will fail to good standards on the first cycle, especially if you're flashing ROMs left and right

how about using a kernel for undervolting? with my current settings it gave me 2 more hours of moderate use , i always keep the brightness at 0 or 25 something like that and no games, just watsapp , nothing else really eats up the battery according to the battery usage

Sounds like you may have a wake lock or something. Go search for better battery stats here on xda and install it to check for that and much more.
As for UV, I recommend against that because it may cause random reboots if over done.
Also remember that every phone is not created equal and may react differently to things like that.
