Is battery calibration a thing? Does it actually work? because http://forum.xda-developers.com/showthread.php?t=1443108 says no. But, some other people say yes.
A lot of people who don't know what they are talking about claim that you must reset your battery stats when flashing new roms, etc, but this is not true. All resetting the stats does, is just that: resets the stats on the settings>battery page. It does not affect battery performance on android.
Your link is a quote from a dev at Google.

The link is a quote from the developer at Google that wrote the software that manages the battery stats file.
She says that clearing it does nothing. That's pretty authoritative.

Sorry - what I mean is that I agree with you and why. Clearly, what you said is true: battery calibration is a waste of time.

Oh gotcha. Yeah it really became a trend around here for awhile. Hopefully the recommendations to reset battery stats is dying off.

If so does it work well on the 3d or do you use a different method?

That will work, but the method I always use is to wip battery stats and let the phone die, fully charge, and then let it die again. After that, the battery will be much better.
This actually does what Viper is talking about. All it does is simply delete the battery stats. Some say it helps, while some articles have said it does not help battery because the stats help tell the phone how to use the battery to its full potential. Personally, when I switched to Vipers rom I used this then emptied/charged it, froze sense and all bloatware through ViperMod (control?) and flashed the SBC kernel. It has been on for 4 hours now, with reddit and texting, and it is at 96%. That is ****ing amazing.
I taped 2 batteries together and they calibrate well, thanks.
Haha sorry about the typo guys and thanks for the advice ill try it when I come back from work tonight and see what happens.

Before wiping bat stats should the battery be at 100 or close to it (seems like stops at 99) and then wipe. Also should I do this with your stock rom first and then apply the test 5 sbc kernal or can i do it with the test kernal already installed?

The battery seemed to last longer after I let it charge for 2 hours past the time the LED turned green for 4 days.

Sent from my Beastly EVO.. And did I mention it has 3D?
What could be causing my battery to go from 20-25 hours of usage down to 7 hours?
It started about the time i flashed the LA2 firmware, I use intratech frankenstein builds, never had a problem before, been flashing since the KE builds.
Things i know aren't the problem:
- apps, I haven't installed any new apps, the battery usage shows no odd app battery consumption
- wifi,bluetooth,3g,gps; I have them turned off most of the time,when i don't need them
- firmware,ROM; i've flashed 3 different ones since the problem started, no change
- bad battery stats, my battery consumption is linear, a straight line from 100% to 1% and it powers off the phone when you would expect it to
Things that could be causing it:
- cache,data wipe; i've never done a wipe of my phone
- new lockscreen, all the firmwares i flashed (LA2,LA4,KPH) since the problem started have the new lockscreen
Thanks in advance for your replies.

Lockscreen is might causing wakelocks, use betterbatterystats to look for any wakelocks.

Agreed here, sounds like a wakelock issue, I have had this before, Not sure of a fix. I have usually just moved on to a new rom which has fixed it

Sorry to hear that.
First post here for definition, rest of thread for solution.
I just upgraded my SGS2 to ICS, since that the battery of my phone draining hell lot quicker than earlier. Earlier it use to go down by 1-2 % in the night (when m sleeping) but after update it go down by 11-12%
actually the battery performance should be better, right?
Sent from my GT-I9100 using Tapatalk
Hi,
I have same feeling. After a week on Slim Ics I can say that with GB my battery life was better. By 10pm everyday I was having left about 40-45% with GB , but with ICS the best I can get is :confuse 30% , mostly about 25% left and I'm having same kind of usage. It's true that with ICS it seems smoother and more responsive .

A fair price to pay.
There are a lot of threads on thus subject if you have a search of the forums.
I had the same issue on upgrading from GB but after following advice and doing some investigation and troubleshooting of rogue apps I now have much better battery life on ics than I ever got on GB.
Read the forums and follow the advice, track down the culprits and you too will reap the benefits

There are LOTS of threads on the subject. Use the search box at the top of the page to look for "battery ics sgs2" or similar and you will turn up pages of information.
The sad thing is the best piece of advice I found was that no two people will have exactly the same solution. You need to identify what is eating your battery using a tool like "Better Battery Stats" or "Go Power Manager". You then need to decide how important the culprits are and remove them or look for updates.
Titanium Backup is useful as it allows you to freeze apps so you can see if they make a difference. It helps if you are rooted as I found several stock apps at the core of my issues. You can't freeze them unless you are rooted.
Siyah Kernel is also very useful, it seems to manage power better than stock. I also found that a factory reset, clearing user data and clearing all of my caches (including Dalvik) helped enormously. It is time consuming to re-install all of your apps from scratch but it does seem to make a huge difference. It looks like some apps retain data from GB that caused issues in ICS.
I found that exchange services were using a huge amount of juice before I cleared all data and caches. That seems to stop completely after the big clear out!
The main thing is no two people seem to have exactly the same problem. It is important therefore that you take a problem solving approach, change one thing at a time and wait long enough to see if it works.
There's your bone, go chew!

Same old, same old.... These are the same tricks that work with EVERY ROM upgrade.... If u get a better battery life outta ICS than u did with GB, u really screwed up installing GB...

i usually get 2 days of battery life on ics 4.0.3....
First of all, you need to be clear whether you upgraded from stock GB to Stock ICS, or a Custom GB ROM to a Custom ICS ROM, since the Custom ROMs do offer better battery life over the stock version.
People here are giving great advice regarding the use of Titanium to freeze any apps that you are not using, e.g. Google+, Samsung bloatware, etc... - this will save the average RAM, hence the battery life. Also, do use Task Manager often (especially before going to sleep) to kill all the background apps.
I installed many Custom ROMs and now running Resurrection v2.1 and very happy with battery life. You must be realistic with expectations - read this http://blog.gsmarena.com/our-samsun...e-test-is-complete-check-out-how-it-did-test/
Overall, if you will do a clean install (format everything - internal/external/MMC and clear cache/Dalvik/battery stats) of Resurrection ICS v2.1 or Litening v3.2, then you should see even an increase in battery life!
Hope it helps and happy flashing ;]]

All you would have to do to put your phone back to factory settings is to download a stock firmware from www.sammobile.com and flash it through odin. I believe the site has flash steps. There's many guides on how to use odin on Google.

Hello,
I was just asking myself if you really need to be at 100% before you flash anything in CMW? Is there any proven point why you should do it or is it just a recommendation? If you flash with less than 100% should I do a battery stats wipe the next time I am at 100%
Thanks Matt

No, but i would recommend at least 50%. The battery will calibrate itself after a couple of charging cycles.

I've never bothered with that, personally... I always thought the battery recommendation was in case you ended up running out of battery partway through a flash. I don't think the battery stats are really affected (well, they haven't been on my phone, and I very rarely flash with 100% battery).
So long as you've got enough that it won't die during the flash, although 50% is a good guideline I guess.

Okay, thanks guys I was thinking the same, mobile odin also lets you flash until 50% so I thought probably it's just for protection to prevent the battery from dying during the flash.
Its really for the noobs whop will spend ten hours flashing and only then read the instructions .

hey guys, last night when i went to sleep i had like 50% battery left on my phone
this morning when i've woke up i wanted to check the phone but it was not responding like it was dead
i ve pulled out the battery and it still didnt want to power up when i pluged it back in. so i went to the charger and it started charging up. battery was dead like 0%.
checked better battery stats to see what was draining it.. nothing odd was there.
im pretty new to this forum so i wanna ask you guys for a lil bit of help here
were there cases like mine and if yes what was the culprit ?
also i'm runin on omega v52. boeffla v5.1 b 8.
thanks in advance
You can install bbs and see what's eating battery. Gud luck.

So then you'll have to wipe and flash a full stock rom using odin, test before adding/restoring anything. If still the same then change the battery.
