Poor Battery Performance of my S 2

Hello everyone,
My S2 only last for 10-13 hours and it drains battery too fast. Tried everything and nothing happened.
In my phone i disabled almost everything which drain battery.
No Facebook
No auto syn of Gmail
Access location is off.
GPS Off
Soft key light/Vibration off
No skype
Disabled Accu weather app
Disabled many others bloat ware
Brightness is set at almost zero level
Better Battery Stats show connectivity wake lock. i think ghis the main problem for drain.
And plz tell me how can i set my phone to only gsm. There is no option for that in phone. In setting it says GSM / wcdma and only wcdma. I set it at gsm/wcdma. Am from Pakistan and here there is no 3g/wcdma.
And if by dialing *#*#4636#*#* i choose gsm, it comes back to gsm/wcdma. Is it draining battery?

<nvm, didn't read properly...>

what ROM are you using ??

What!?
You wrote "My S2 only last for 10-13 hours and it drains battery too fast."
On attached screenshot you have 80% left after 6 hours of usages whereas 48% is used by Screen and 17% is used by Boat Browser.
You have to expect about 1~1½ % drain per hour ... even if you don't use your phone.
Screen drains a lot depending of your amount of Brightness! If you can get 4 hours Screen On, your happy.
From what I can see ... your battery time is totally normal!

I have Stock rom ICS 4.0.4
My cellphone is branded version and it comes from 3 Mobile UK.

no its not normal.. today i charged it and not use it for 2 hours.. i put it on airplane mode and leave it for 2 hours after 100% charge, to check the partial wakelocks.
I thought this time connectivity service wakelock doesn't appear but it does.
i thought connectivity service wakelock is due to mobile signal but when i put it on airplan mode for 2 hrs this partial wakelock still appear.

Hmm , I am not a Fan of ICS though, but the battery time which you have shared (Just Saw it) LOL , it is totally fine , and secondly , use a safe kernel to root the phone (PhilZ Kernel) link is in my signature , and then Flash NeatROM Lite v4.0 , my battery lasts easily 18-20h and i am a heavy user of the phone with Calls , Messaging , FB , Twitter, Whatsapp, Viber & Tapatalk

PLS STOP with all this Juice Defender nonsense! A task killer often will drain your battery even more ... some processes will just restart again after you have killed it.
On newer Android version (GB and ICS) I haven't found any task killers that actually prolonged my battery time.
Adjust your screen brightness as low as possible, use a dark backgrounds and themes, get rid of unnecessary Widgets and Live Screen backgrounds, Sync Mail, Calendar, Twitter only when needed ... and then you will be fine :good:

High battery consumption by stock kernel

Hi guys,
Last night I had 15% drop at the battery, wifi was off, gps was on.
From gsam i saw that the kernel drained the most.
Does anyone have any ideas how to avoid this kind of battery draining?
Few days after I got the phone I had 0%(!) battery drain at night and it was along few night, for some reason i cant reach same level of battery drain at night now.
Thanks in advance.

You have some weird apps keeping your phone awake, nova launcher? Have never seen that one in my list. Install betterbatterystats to see the wake locks in detail.

I don't think that's a wakelock list buddy, it's just listing which processes used the battery the most.
Apex, run this for a few hours and post a screenshot.

Betterbatterystats is an app that shows into detail the wakelocks, alarms, frequencies etc. Don't know the app you gave, maybe it does the same.
http://forum.xda-developers.com/showthread.php?t=1179809

ok so here are the findings:
I froze news&weather since i dont use it and put taptalk on 3 hours intervals of checking.
I'll read more into BBS analysis to retrieve further information

anyone?

It doesn't seem like there are any weird wakelocks. How many hours of screen on time do you get?
Sent from my Nexus 4 using xda app-developers app

Turn off your GPS.
Why do you need it on when you're sleeping? do you sleep walk? Don't answer that. Lol
I recommend downloading this app called "greenify" and find that app and hibernate it.
Sent from my Nexus 4 using Tapatalk 2

I also installed greenify, but it just doesnt seem to work well... every now and then, when I check on greenify, I need to re-freeze the Maps App, even though I didnt start it in the mean time.
Speaking of which, why does Maps keep the phone awake that long (or wake it that often) and drain so much battery at all?
anyone got an answer to this?

Google services using battery

Hey guys, I just noticed that Google services has been using up a good deal of battery for the past few days... My autosync is off, gps off but still has it using up a fifth of my battery.. Anyone else have similar problems?

I have noticed that even in flight mode and screen off, there is a significant amount of battery drain (i saw 20% less in 6 hrs). With previews phone.. would be 2 to 5 %. I think that the key would be to underclock it in iddle mode

Do you have Google Now and maps location reporting enabled? Those two are major battery hogs.
Sent from my SAMSUNG-SGH-I337 using Tapatalk 2

This worked for me and a friend. Go to Application manager then Google Play services and click uninstall updates. After uninstalling launch Hangouts. It will tell you that you need to update at which point do so. Hope that helps you out like it did me.

I am willing to bet these drains all occur after Google app updates? It seems that most Google apps want to eat battery the first cycle after they were updated. What I have noticed though, is that even though the "battery" stats report Google services as using a lot of percentage, the actually time the phone takes before it needs charged is about the same as when battery stats doesn't report Google services as eating battery.
So, see if "Google services" or Maps or any other Google app doesn't settle down after a cycle and also check to see if it really is shortening the time your phone needs between charges. I suspect it might just be temporary or maybe reported to the phone wrong.
Except for Google Music, freeze it, it will eat your data.

i uninstalled the play services update, and i disabled location services..seems to be fine now. ill turn it back on after a while to see if problem is caused by updates.

Did you mean when the screen is off? Because obviously it status awake while the screen is on. But there may be an app keeping it awake. Make sure all your apps are trusted

when the screen is on. ive never experienced this when its on Jellybean 4.3
and all the apps ive downloaded are from Google Play Store of course.

I'd go for a wakelock detecting app like "better battery stats" or "wakelock detector" to see which app could be the culprit. "Greenify" could then be used to block that app from keeping your tablet awake.
I personally do have no issues with standby whatsoever. I'd say I lose about 3-4% of battery during the day on 4.4. (WLAN and sync on all day, but I'm taking it to work where I have no WLAN I could use). I guess I had the same mimimum drain on 4.3. So standby couldn't be better on N10 in my opinion.
I only had one issue so far, where at about 25% of battery left it suddenly began to drain like 10-15% an hour, thus leading to my N10 shutting off after about 2 hours. No idea what caused that drain in standby.

I second that, get better battery stats or something similar to see what's keeping it awake.

mhm ... will not install 4.4 if the battery life is that terrible. Did you guys control the typical Google apps, which usually like to eat a lot of battery?

I have this since 4.4.2 on my Nexus 10 and 7v2. Not on the 5. My N10 uses almost every juice for Android OS. Before it used 5% for 1-2 days for standby. Now 3 hours. See screenshot. Is this normal?
And it wasn't awake. See other screenshot.

Battery help needed - 14 hours until flat!

As per the title, I am finding on a daily basis that I am only getting 14-15 hours Max.
I only have one homescreen with no Widgets on it.
I have 3 mail accounts, 2 are exchange, 1 Gmail.
No live wallpaper,
Been in a good signal area most of the time, send maybe 10 texts a day, very few calls. No music listening, no picture taking.
Phone is a uk phone d802 supplied by 3 but reflashed with generic open firmware to remove 3 bloat.
Any ideas what's going on or how I try to resolve it?

Don't know if this helps to see where problem is
Sent from my LG-D802 using XDA Premium 4 mobile app

Might be an app sucking the battery or a bad flash. Try reflashing the firmware. Do a factory reset before the flash and one afterwards.
Also, install GSAM battery monitor.

Disabling knock on might help as well. However if you do find a solution without disabling knock on please let me know.

try regular procedure found everywhere on how to determine wakelock.
also check for battery unfriendly settings. like email sync settings, push is friendliest, check-in every minute keeps phone awake lol.
but most importantly, state what you do in these 14 hours. How many is the screen on. etc.

I think I can do this from the standard task manager can't I? Sure there is an option to stop services. Don't really use Google now so will not miss that.
Screen time on from my screenshot yesterday was 12% don't know if that's considered high etc.

yeah, set Gmail to push,

in Google settings also
turn backup off,
reboot, check if settings were saved
install betterbatterystats from play or this forum. with that check kernel and partials. Google what they are and mean.
Also check deep sleep percentage in cpu spy. should be, pending you keeping awake around 95% in period off charger.
