Q Battery life - Galaxy S II Q&A, Help & Troubleshooting

hi folks, battery life for me is a joke..roughly 14 hours with 2.30 hours screen time..thats completely stock,deodexed and rooted.. installed better battery stats and theres nothing draining it i can see..i have gps disabled, auto sync off, brightness down, location off..
thats with both a genuine samsung batt and a aftermarket one..
would i be best to try a different kernal..

You can try to remove all the system apps that you do not use or freeze them by greenify.
You can also try a custom kernel as dorimanx v.8.43 and turn down voltages arranging other aspects of the kernel through the application STweaks.
You can try the apolo kernel that already has versions with rated energy saving parameters

hi folks, just an update..
i installed apolo v4 regular and cleared the davilk cache (maybe this was the issue from the start)
now my stats read: - 23h30m on battery and screen on for 3h31mins, with 16% battery left, pretty impressed with that
maybe i can afford to turn the brightness up a little bit now, hehe

[Q] Battary Life Issue...Need Help

My X10a used to give a day worth of battery life when I was on Android 1.6 after upgrading to 2.1.A.0.435 it almost got doubles 2 days. A week back I installed black theme using xRecovery and JIT (I didn't take backup before installing it ).
Now the battery is good for 10 -12 hours only. I checked the battery usage, it is show 60% cell stand by and 20% display, my usage doesn't change at all.
Can any tell me solution without doing the repair will greatly appreciated
Thanks
Try going into xRecovery menu and do " wipe battery stats ". Could be you've turned up the brightness, and your display is eating battery?
Maybe you already do this, but these next ones improve battery life in general. Not that it would explain your change... Use the app APNdroid to disable data when you aren't using it. It has a no/off toggle widget for the homescreen that works great. Set WIFI to "off when screen off" along with APNdroid, and use Advanced Task Killer app set to aggressive, medium security, and "auto kill when a screen off". Set all system apps and any apps that you always want running to "ignore" auto kill.
There is argument that task killers actually do more harm than good or kills battery, but that is if you didn't set it up right. At least on 2.1. New versions of Android don't need task killers. If you don't like task killers, skip that. It's better to have no task killers at all than to have one that's set up wrong. Never set task killer on a timer, like every 30 minutes.
When I did all these things I still have 30%+ the next day if I forget to charge it at night with HEAVY use. Before I didn't always make it through the day. Hope this helps.
Thanks for your answer.
I tried wiping battery and then what I found is my phone is using much more power standy mode. The application have not changed and I already use advance task killer in aggressive mode
can JIT increase power consumption in standy by mode?
Don't know if this will help, but try using a fresh download of JIT custom zip. Then going into xRecovery/advanced options and wipe Dalvik Cache and then reinstall JIT. Also, try disabling task killer if you are still having problems.
i've had my x10 for 9 months and last month i noticed a change in my battery life even when i haven't made any significant changes to my normal usage (and settings). my old x1's battery lasted about 11-12 months... and i'm a moderate to heavy user. so it could just be your battery beginning see it's way out.
agentJBM:
I tried reinstalling after wiping Dalvik Cache but this didn't work, I'm stilling seeing drop in battery a percent a minute then phone on otherwise cell standby using the battery.
I guess I need to start from repairing again and installing JIT. Only thing I can think is that JIT is for global ROM but I had Canadian Rogers ROM
if that didn't work then I'll follow azian_advanced advise and order a new battery
While you're at it, see if you have the same problem before you enable JIT after repair software. That will give you an idea if it's the battery.
Also, try the procedure in the thread titled "[Guide] X10 Battery Calibration" found in the general section. I'd provide a link, but I am on my kick ass X10a.
Repair made big difference, I installed all my apps but haven't configured by emails yet but drop of 5% in whole night versus 90% drop earlier. I haven't installed JIT yet and i thinking leaving it alone for now
its crazy how jit seems to effect each phone so differently

improving battery life???

Hi im having problemswith my battery. it goes dry very fast. before i updated my phone to 2.3.3 i used Advanced Task Killer but now its not working like it did before. any applications that i can use with 2.3.3 that are efficient like the Advanced Task Killer was with 2.1
get apn droid and disable 3g when you are not using your internet, always turn wifi off when not using it. root and use setcpu to make your cpu go to lowest speed when screen is locked
also read this http://forum.xda-developers.com/showthread.php?t=1071885
use battery calibrator software from the market and follow the instructions! Once the battery is calibrated then install CPU master anuntu from market and select the maximum 578mhz and minimal 245.76mhz with scaling on demand. Hopefully this should improve the battery life as it did with mines!
first flash a custom kernel like Doomkernel http://forum.xda-developers.com/showthread.php?t=1226826
then install a cpu manger like setCPU (http://forum.mobilism.org/viewtopic.php?f=438&t=214414&hilit=setCPU) or antutu CPU master
then change the governor to smartassV2
then when you are charging your phone charge it up to 100% -unplug charger- switch off phone- remove battery - insert charger - then the battery - then switch on phone and charge until 100%
use common methods such as turning off Data , WiFi, Bluetooth , GPS etc...
i got almost 3 days battery life by doing this !!!

[Q] Battery drain issues on CM7.1

Hi,
I'm using the following rom : http://forum.xda-developers.com/showthread.php?t=1263292 ( CyanogenMod 7.1-cooper-KANG-RC1 Android 2.3.7 ) with a XXKPE kernel, and I'm getting very bad battery life. About 30 minutes of active wireless activity, a few calls and idle time otherwise, and the battery is at 20% after being fully charged in the beginning.
I have seen some attempts to map roms and kernels in terms of battery usage, but haven't seen this one mentioned in the list. Are there any known issues with this rom? (Couldn't fine any while searching)? Is this expected life expectancy for the ace? The phone is new so I don't think its the battery itself.
Also, I want to be able to easily control certain features with one click (for example, turn off 3G, mobile data and sync quickly). Is it possible to do such a thing?
With CM, go to Settings > CyanogenMod Settings > Interface > Notification Power Widget > Widget Buttons
then tick the stuff you want to appear on notification, so u can one click configure it.
As for battery saving, I'd recommend Juice Defender Ultimate, I've been using my phone for 7Hours with Wifi on non-stop, and now is at 68% from 100%. Juice Defender Ultimate is really good, if your willing to take some time to configure it.
EDIT: As for ROM, im using ICS Final with SlaidFastMod. I moved from CM7.1 because of the battery life. With Juice Defender, it could barely last 1 day with minimum usage (mostly idle)
Or you could make power saving profiles. using Tasker.
Thanks guys!
- Tasker seems really complicated, so I'll try to avoid it for now (looks like a big config effort needs to be put in)
- I'm using Juice Defender (free) for now, if that doesn't change much I'll probably try ultimate.
- The power widget buttons are helpful, was looking for that, thanks!
- The rom change I'm a bit worried about. Is CM7.1 known for being a battery hog on ace? Are the ICS roms stable yet?

Battery problems

Hi folks, I've been doing a bit of scouting and haven't been able to find a solution as of yet so hoping somebody here can help me. I upgraded to ICS a couple of days ago from 2.3 and since then my battery has been going a bit odd.
My phone wouldn't come out of sleep and i kept having to do battery pulls to bring it back to life. I figured this was probably to do with my SetCPU setting being too low (200-500MHz for screen off) so i disabled the profiles and it still was happening. Have deleted SetCPU altogether and it has improved a tad bit. But now my phone does occasionally go into sleep mode and won't wake until i do a battery pull. But when i bring it back to life my battery is 15-30% lower than from before I did the pull.
I'm running 4.0.3
Sensation Rom 3.5
Siyah Kernal v3.3.2
PDA version XWLPG
Baseband DXLP9
I've attached two screenshots to show properly what I mean. Scrolling through ExTweaks shows me that siyah kernel itself also can change clock speed but there's too many options there for me to know safely what I'm doing. I've done battery recalibration twice with no luck so far.
Thanks in advance for any help!
flash stock rom and root and reflash sensation rom by doing a full wipe
do a full wipe, and reflash the rom.
Then see if you still have problems.
Then install your apps again, if you then ahve problems, you know your apps are causing it
You can also install betterbatterystats (free on xda), that app will tell you which app is causing wakelocks

- Internet surf / 10 - 15 minutes a day
- E-mail check / 2 - 3 times a day
Problem:
* My battery drains very very fast when screen is on
Questions go in the q&a forum, report your own post and ask a moderator to move it for you.
Everyone's battery drains fast with the screen on, at best you'll get 4 or 5 hours screen on time per battery.
If you're getting half that then search and read for the usual suspects and solutions.

Maybe you are using so many apps
Try boeffla kernel, use zzmoove with moderate or battery yank profile (or if performance is not a big thing for you user battery plus profile), don't undervolt it, just turn down the max clock of cpu to 1000mhz and max of gpu to 400mhz, also disable touch boost, logging and don't use swap.
Turn down your brightness, or use -5 auto brightness, enable CABC (content adaptive brightness control) undes sys settings>my device>screen>scroll to bottom.
With these settings you just have to have at least 4-5h of screen on time, if not, replace your battery.
Also, make 2-3 full charging cycles.
And if you tried the combination like i mentioned above, and you still cannot achieve that results, there is 100% that you have either battery hogging apps or a faulty battery.
Please charge your phone to 100%, and at 1-5% make a screenshot of better battery stats, it will be a better evidence in your usage.
