hello
I'm currently using miui rom 1.9.16 with siyah kernel v.2. 6.1+
with low usage and juice defender the battery is quite good but if i use some apps and 3g data it can go to 10% in 6-10 hours
I'm playing a game called age of legends that seems to take most battery (about 50%) .. with my carrier rom i think battery was better but still quite bad
maybe I'm not using siyah good enough idk
any help will be appreciated

The SGS2 screen takes a lot of battery, so if you play a game for long, it could affect the battery duration.
yeh but that will be on display usage and i have it on 10% and i usually set my brightness very low so it should save some as well

I believe Miui is the problem. Miui is a battery drainer.
Your screen uses batterie. This has nothing to do with your rom or kernel.
Avoid white screens/backgrounds as this will use more batterie then dark ones.
I know the screen takes battery .. but the system shows battery usage percentage and screen is maybe at 10%.. i think the game is the problem but it wasn't so bad with other rom so there's probably some problem with miui/siyah competabilty with the game.. the game is over 50% according to the battery usage

Don't separate game from screen, unless you're able to play that game with the screen off...
The total consumption is 60% during the time you're playing the game.
I don't know if the fault is the game itself, but when playing games for a couple of hours, it drains battery a lot. That is a fact.
If you use your phone to play like 2+ hours, you probably will be charging it at night since you will be out of battery. It's not a phone or battery problem, games always tend to drain battery.
I need to charge 1-2 times a day for it to last until the night... well i guess I'll just need to try some more roms and kernels to see if it's getting better
thanks for the help everyone

I haven't got over 2 hours of screen on time in a hella long time. In my stats I'm not getting any strange results, screen is getting 60% and everything else is under 10% which is normal. I was getting very good battery life in gingerbread but ever since ics roms came out I haven't got anything good and its been a while. Why I think it might be my battery is because if its charging it will reach 110 degrees even if I'm leaving it alone. Screen brightness is under half and I've dropped about 5% just typing this out. Under moderate use the phone will seem to heat up more than it should, so I'm just looking for a little input

I have seen many post that people talk about heat and battery drain after flashing an ICS ROM... So it might not be your battery, what ROM and kernel are you running does it do it with screen off and in deep sleeping? I have some more battery drain on ICS but never heat issues even watching HD videos wont heat up the phone. It sounds like you have an app spiking your CPU, try tuning on Show CPU usage in menu / system settings / developer options / Show CPU usage at idle with wifi on mine was approx. around 0.08/1.00/1.20 - 0.50/1.50/2.0 I hope some can give you more info how to check CPU info... GL here is a link to DL CPU Spy it might be able to help find the problem....

Check for better ROM/Kernel combos
Having flashed a lot of ROMs and Kernels, if they don't work well together (and sometimes if they do) your battery life is severely impacted. Since the change came when you updates to ICS, it seems likely thats the cause. Try finding kernels that allow you to use SetCPU or another regulator. You can set power modes to conserve battery, set a scheduler, and most importantly, set up profiles to keep it from heating up!
In short, search the forums for good ROMs, there are no shortage and some are designed to be battery friendly, best of luck!
PS. sometimes after flashing a new ROM, your battery calibration will be off and you'll get wild fluctuations or usage. Some say you can do a process to recalibrate, others say it doesn't work, but it doesn't hurt to try it yourself.

Hi,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):
http://forum.xda-developers.com/showpost.php?p=26755476&postcount=850
With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

Strange, I am on stock and can make almost whole day with 3-4h screen time. Sounds like some issue either with battery or with the phone.

get a 2000 mha battery over ebay
I have been used 2000mah battery, miui 2.8.3 + siyah 4.0.1 kernel, no serious battery life issue :good:
I have a 1800mah battery, its actually not that much better than the stock battery, but doesn't the 2000mah add extra thickness?

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

If it occurs with every rom you have could it be app related, wiggets or syncing too frequently?

That's what I thought but I've analysed my apps with betterbatterystats and gsapp, nothing suspicious came up and wakelocks are always kernel related. I've tried several kernels as well

Get cpu spy from the play store to see if your device is deep sleeping. Also, you can try 1900mah anker battery. I got two and a charger off eBay for $25 can. Definitely a good deal

Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.

maybe your battery is bad i bought a great 2500mah battery on ebay http://www.ebay.com/itm/2500mAh-Ext...ccessories&hash=item4ab6494de0#ht_2481wt_1163
that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time. And i'll try the suggested rom after I've given this one a few more days on the undervolting

For BBS, anything over 1% is something that needs to be fixed. Keep in mind you need a good sample time (like over 5hrs)

Hmm looks normal, I would get the 2000 mah Samsung Original Battery because 10 hours and already on 38% battery is not so good in my opinion.

I've taken a few screenshots of bbs, somehow the kernel wake lock is completely empty which is odd
Also I only need the battery to last about 15h with 3-4h of screen on time to get me through the day!

Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.
Recently had some issues with battery life so went out and did some research asked some questions and i'm quite happy with the result.
Started at 95% Battery
Down to 10%
16h 17m 50s on battery
Screen time on: 3h 46m 49s
Wi-Fi been on for about half of that
Used Chrome to browse the web
Played some Angry Birds
Played some Bad Pigs
Checked Facebook/Twitter
Could improve this more i guess as i'm currently not running full battery profiles on Siyah but quite please. Just wanted to compare to others and see if its any good or not.
On a side note my mother in-law came round today check her stats 1d 12h on her phone and still had 40% battery on stock ICS lol but she only uses it to text/call.
I'm running omega Rom v29 with phenomenal medium kernel and powwersave mode on. I've Been using my phone most of day for calls light browsing and xda I'm currently sitting at 52 percent with 13h since last charge

to achieve insane battery life. useany JB based Samsung ROM. Freeze anything you dont use via TB. Then Flash latest perseus Kernal. set your phone to power saving mode. there no lag on power saving mode with his kernel. finally,drain your battery completely. turn it on, charge to 100. then turn off the phone, keep chARging to full. and use it for couple days, then report back

Hey guys, I installed Cm 9.1.5 by hephappy, when adding the google account, I turned off Google Account Backup, and from then my phone does not drain battery like hell... Beware these are just my findings... Your milage may vary.

Never used google backup and my battery drains only when gaming or watching movies. Display is the eater.
If I use phone only for ril and internet it last all day, during night sucks only 5% in 8hrs with 2G on.
I used CM9 without Gapps, even then the maximum I could get was 2 days, with Oxygen-GB its more than 3 days with heavier use than ICS. The reason for poor battery on ICS is our outdated hardware, on high end phones ICS/JB increase battery timings.
if i use my phone for calls(1-2hours a day) and sms (30 sms a day) it lasts for 5 days on icy snap 1.5. i only deleted some apps in system and added only those files needed for play to work oh and i have caf kernel.
if i use it a lot it lasts for 2 days.
i think the 25% brightness setting helps a lot to.
