Okay so I've been flashing ROM's on my xperia mini (st15i) since November-December of last year. Recently i have seen drastic battery stand-by on my device. I usually change my ROM frequently. I noticed that my device at night, on stand-by mode goes from about 70% to 30% with only WiFi on and brightness set to low! This shouldn't happen i guess! Currently I'm on PA 2.57 i.e android 4.1.2. And while typing this all, it went from 70% to 65%! Everything's off except for WiFi with no calls/texts! I use whats-app/kik messenger so switching off the WiFi is not at all a way to increase battery.
I also used battery calibration twice or thrice, flashed various ROM's, used various tweaks, but still no improvement.
I really really need some help and advice from all.
Thank you,
Regards,
Ishan :good:
Hi
Try using BetterBatterystats to find out which component drains your battery.
Have you unlocked bootloader, if yes try different kernels..
Theres an app batteryguru try that too.
Bad battery
I'm using xperia mini pro./.... and sometimes it looks like my device... and try a new rom which has a long battery feature, try a new kernel,... delete some unnecessary softwares and turn off wifi, 3g,4g, reduce screen light,.... and your battery may be corrupted..
change with diferent kernel bro!! try to reflash new other rom, tweak with only one script ex supercharger

Hi Guyz,
I am using optimus one for the past 6 months and have 3 major problems..
1. Scrolling in Launcher pro which was silky smooth once upon a time stutters a lot now a days. i tried different roms, posted a thread on this forum , tried the suggestions but still the same issue exists. When the rom is new, before my set of apps are installed, launcher pro works smooth. but once my apps are installed, it gets back to stutter pro. PLease help
2. Battery drain. - I used to get One and half days of battery without the data on. Its been a week since i subscribed to unlimited gprs pack and with the data on, on 2g mode, with auto sync off, my battery s drained a lot. even in stock rom, it went down from 70 percent to 8 percent in 7 hours. with franco kernel. I also tried froyofinal, void, lol, mik gingerbread, stock gingerbread roms and .. same results.... i used facebook and downloaded a lot durin tht 7 hours. is tht normal...?
3. Minor issue.. When i lock the device and then press back key or any other key after the device is locked, for a split second i get to see the desktop and then only the lock screen appears. some times i used to see a blurred dotted image(we get it wen the cable connection is off). and then the lock screen. This issue exists in stock rom with franco kernel itself... Y?
Please help guyz.....
1. You say once upon a time your launcher pro was smooth. Try reverting to the same configuration you had then and see if this issue is fixed.
2. If you did downloads, then I would say it may be normal. Keep it idle, i.e only a few calls and sms and then see the drain.
3. This happens in franco kernel. Small issue.
make sure u dont use live wallpapers.. they really screw up the phones performance..
for battery drain its.. quite good.. if u downloaded a lot. calibrate battery and then try once again.
i would say u should try miks 6.5.5 with fk v18 cfs.. it gives best battery life with 2g.. and has best performance too
I tried mik's Rom . Still the battery drain is noticeable. And more over the call volume s too loud . Is there any way to reduce it .
And i also calibrated the battery and i don't use live wallpaper. Any other suggestions

J.k signing off using XDA app on OPTIMUS PRIME
Any live widgets that you use, they do contribute lots in battery drain
Use startup manager and see what apps are loaded on startup and remain in memory there might be some you will like to remove, maps also causes lot of battery drain, remove it from startup

I'm also facing this issue. I'm using CM7 6.5.4 with v18.1 Franco's Kernel. People have said v18.1 kernel had very bad battery life and I am experiencing this like everyone else. The performance of 18.1 is amazing, but battery is being drained to fast. I'm going to revert to a lower version of the kernel and see if battery life is better.

That right there. You are obviously installing one or a few apps that are taking up much CPU. You need to try and scale back. I would install your apps back one at a time until you find what app(s) might be causing your stutter.
And quit bumping your topic 2-3 times in a day... FFS people will get to you, chill....
hi just wanted to ask if there is a ROM there that is as close as the original ROM of the samsung galaxy s II in terms of apps and looks but is tweaked for better battery perfomance?
cause my dad bought a SGSII almost a week now, and we only get about 5-6 hrs of it using only it. already did about 4 charge cycles. (4 only cause most of the time the GSII is off, my dad's getting a hang it yet)
config:
- stock android 2.3.3
- 3g auto
- auto backlight (but we are inside a mall so the backlight is isn't that bright & have strong signal)
- auto sync is off
- background data is on
- haptic feedback is off
- audible selection is off
- fast dormancy is off
- power saving mode is on
- juice defender app in balanced setting
apps running:
-skype
-messenger
it drains a LOT even in standby a lot more when using it (browsing, not yet chatting). my hd2 is much more efficient knowing it is not a native android smartphone...
is there a tweaked battery efficient rom there that is as close or at least still looks as the stock?
You can do three things,
1- Install Better Battery Stats and see under 'Partial Wakelocks' to see whats running on background.
2- Stay on Stock ROM and flash a kernel which allows Voltage tweaks and install SetCPU and Undervolt CPU. Ninphetamine 2.1.3 is such a kernel.
3- If thats too complicated for you, then flash an Undervolted kernel, like SpeedMod.
I won't advise you to change to a Custom ROM for battery backup betterment. But doing the above processes will certainly save some.

thanks for the quick reply, so custom kernels work with the stock rom...i thought it won't. i'm not that familiar yet with native androids cause in HD2 most of the undervolted kernels there are already built in the roms so i don't change it that much now with the NAND builds....but anyway, i'll try for the mean time # 1 & 3....i'm not that into that #2 tweaks yet in a phone that is not really mine....
It is proven that Stock ROM's with custom Kernels have sweet battery life. As with Stock ROM's they haven't tweaked anything, it's just stock and you flash what YOU want, whereas a custom ROM you're getting things you dont infact need.
I keep going back and forth from Custom ROM's to Stock ROM's.
Hi
I would also recommend looking at SicOpat's ROM (http://forum.xda-developers.com/showthread.php?t=1183774)
This is essentially a stock, rooted ROM with a custom kernel and I find it exceptionally good.
The other thing I would recommend then is to install Titanium Backup and freeze/uninstall a lot of the Samsung apps - WiFi Sharing, software update, *hub stuff. Removing these has a very positive impact on battery life.
Hope this helps.

I have also been troubleshooting poor battery life on my phone. I used to lose 10-15% an hour just idling. I reflashed Stock KH3 with the KH3 CF-ROOT kernel and reinstalled a few things (twitter, yahoo messenger, google voice, and some apps that don't sync data). Currently I had 18hrs now with 60% left. MUCH better. A lot of the time the phone was idle but I did listen to music, play some games, and browse the internet/chat, use wifi a bit. Phone only lost like 4-6% overnight. (sorry I don't have hard figures but I didn't document any of it on paper). I'm trying to find out what was killing my battery so I am installing things little by little but I would definitely recommend stock KH3. Seems great so far.
I think your problem lies with the wifi-sharing battery bug. I hear this is updated in newer roms. This was the biggest battery hog on my phone, but after noticing it, my battery life is excellent now.
When Wifi is turned on/off this erroneous process starts in the background called "Wifi-Sharing". It hides and drains your battery at a VERY fast rate. The remedy is simply to "Force Stop" this process after you use Wifi.
Let us know if that helps.
You could root the phone and install Titanium to freeze this process permanently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
sorry for the wrong forum i got messed up in opening a lot of samsung galaxy sII threads....
i dont see the "wifi sharing" in my dad's GSII when we used it. and as with kies, i think JKG2 firmware is the latest, so i assume that the wifi sharing bug has been fixed there, yes?
i know it would consume a lot since the GSII has a big "engine" but i didn't expect it to eat a lot even on standby with only YM and SKype messengers running in the background.
i'm still observing it. i'm still running stock.
EDIT: i just used wifi to download an app then when look for running apps, i saw "wifi-sharing" is running but i didn't even turned it on
i just flashed Speedmod T38 kernel (it seemed less complicated to use ) now observing if my dad's SGSII gets better
I've looked through the custom roms listed and theres not a whole lot of information given. I'm currently using Wolf_Xperia_4.0.0 and the battery life is kinda horrid.
I prefer Froyo or Gingerbread and want use of my camera. Can anybody help me out with a name or a link?
see if u want gud battery life then go for this Rom with stock kernel ...the battery life is pretty gud as i have experienced !!
http://forum.xda-developers.com/showthread.php?t=1259028
check if it works out for u ..the camera is same as the Stock one only
Thank me if i helped u
I've had good battery life with WB 4.0.4c and so far doing okay with WB 5.0.0, but honestly since everyone's usage is different it's probably better to experiment with different roms rather than have someone tell you which one is best.
I had pretty decent battery life on WB 4.0.4c until I unlocked my boot loader. I used to get two or three days out of it, but this reduced to just six hours. I'm on WB 5.0.0 now and have re-locked my boot loader. Battery life is good. There are most deffinitely issues related to having your boot loader unlocked so if you have unlocked it then I would seriously consider locking it again if you value your battery life.
Thanks guys, going to look into the one linked. What is the WB one you mentioned?
My aunt is a waitress at a busy restaraunt... she gets up and works 8 busy hours (so not on her phone every 5 seconds, maybe checks texts twice a day?) and she gets home below 50% each day. That's pretty horrible.
WB is Wolfbreak's rom. To follow up to my previous post the issue effecting me was the fact that with an unlocked bootloader my phone was not going into deepsleep which was a known issue. This was fixed in DooMLoRD's DooMKernel v05. I have now unlocked my bootloader again and using that kernel along with WB v5. Battery life is good again. I've lost 12% in the past 16 hours. You may also wish to consider calibrating your battery which basically involves charging it to 100%, resetting your battery stats and charging again from 88% and repeating that process a few times. There is a thread about it somewhere. Sorry can't post links right now as I don't have enough posts. Hope this info helps the OP or anyone else with battery issues.
Wolfbreak's rom can be found in the XPERIA X10 Android Development forum. It's a popular thread, can't miss it.
Also to add on, if battery life is a concern, have you tried adjusting the settings? Perhaps turning down the brightness, changing wifi sleep policy, turning off syncing, etc. I would also definitely look into undervolting.
OK, I've searched for information about this and found little, so if there is a thread already please point me to it.
My battery life has been terrible of late. According to my phone, WiFi is what is pulling the most battery (about 56%). I never really had this problem before switching ROMs. Before I had the problem, I was running z's FreeXperia 2.2 ROM and could get two-three days of battery life without turning WiFi off. Now I am running Wolf's V6 and have to charge my phone every night to keep it from dying. I've tried the battery calibration app, wiping battery stats, and the battery life guide. This problem has occurred with all my 2.3 ROMs that I've flashed, so I know it's not the ROM itself. Has anyone else had this problem? I'm thinking I will use PC Companion to repair back to 2.1 then flash back to 2.3. My hope is something messed with WiFi during previous flash. Anyway, I thought I'd check here before I went flashing my phone to death again.
Also, I know someone will say 'just turn off WiFi,' but I don't have unlimited data (thanks AT&T) so I keep my WiFi on so I don't run up my data usage.
Which kernel ru using for wolfs Rom the stock or custom ...i think stock kernel gives a better battery life compared to the custom...and which all kernel did u try for his Rom
Sent from my X10i using XDA App
I'm running the stock kernel. I've figured out that WiFi isn't the problem. I switched WiFi to be turn off when phone shuts down and that helped, but it's still terrible battery life. I had it fully charged last night before I went to bed. I used it lightly before going to sleep and woke up this morning at 81%. No reason the phone should be draining that quickly. Now cell standby is 39% of battery usage and phone idle is 32% of usage. WiFi is down to 20% with new setting. I guess I need to learn how to do screenshots.
Right now I'm thinking something must not have happened correctly when I flashed the baseband/kernel, because I've tried every piece of advice on this forum. Will reflash back to stock and start there. Will report back to say if that helped.
I have the same issue but right after installing fb 2.0, before that it was awesome
Just an update on the "problem." I flashed back to 2.1 then flashed Wolfbreak v6 twice to try and solve the problem. I also didnt do a full restore on one flash hoping to figure something out. Finally, after having my phone freak out on me, I decided to flash the stock x10a 2.3 firmware. Battery life is back to pre-wolfbreak levels. Wondering if the whole x10i vs. x10a is causing a problem as wolfbreak's rom is for the "i" and I have an "a"
Running FPS uncap on stock rom and it performs well for me. Satisfied for now...until ICS rom
I installed cm11 on my s2 a while ago using the installer and since then im trying to figure out the reason for the huge battery drain. Cm works great but it drains the battery in an average rate of 19% per hour (a special app did the math,and i can clearly see for myself ). I dont do anything more than music, surfing and whatsapp. Android stats usually say the screen is the no1 battery drainer. Android os second.
I searched the internet and tried every possible tip there was. IMO the only thing I hadn't tried is flashing different modem and different kernel (didn't find good guides for it and was afraid to brick the device)
What I have tried:
1. Flashed neatrom just to compare. A little improvement but still not like old days and of its not a good performance like cm.
2. Went back to cm through recovery backup and Used battery stats, taking permissions away from every app with a redundant wake/cpu lock.
3. Got new battery, assuming the problem may have to do with an old battery (bought the device 2yrs ago)
4. Calibrated battery both with the app and also using the manual trick (chrage while phone off, take batter out, wait five mins and put back in).
5. Tried different governors.
Might be forgetting other things. Nothing works!
What can I do? I really wanna use cm and not get lost flashing less good roms.
Thanks
This device uses an old Exynos SoC optimized for Android 4.1, In new versions is normal battery performance loss because there is more consumption of resources
It also warms up and all.... You recommend flashing older version of cm?

Yes, only if you really need more battery life. I have a Galaxy S Advance, who died in the 4.1, Battery life in 4.4(CM) is 30% lower than the official 4.1.
