Battery issue.

Can someone plz tell me if that's normal
Sent from my GT-I9100 using XDA Premium App

Completely normal. Looks exactly how mine (and my other 4 Galaxy S2's) battery consumption looked.

There's threads open regarding battery issues already pal

You had your screen on for most of that 7-8 hour period, and the phone was awake, doing something. This is totally normal.

How come some say their battery lasts 15 - 20 hours and mine bearly 8 ?
Does yours always hit on the back like mine does ?

Becuase your phone was in use for a lot of that time.
Normally I get 7-10 hours battery life with my semi-heavy usage.
But yesterday I tested to see if I could get more, I only used the phone for four 5 minute phone calls, tonnes of texts, a little bit of web browsing and a little bit of youtube on 3G and wifi. No games or anything, and the battery still had 40% left after 20 1/2 hours.
But with my normal usage as i said, I get 7 - 10 hours.

Do a factory reset and see if the problem persists.

wow that is exactly what I am doing now too
was charging twice a day for a week and finally got tired. limited my heavy-graphics gaming from 2-3 hours a day to half hour, now 16 and a half hours past charge, I have 5% left and I am starting to think "how the heck do I discharge to 1% quicker so I have time to charge before I leave work tonight"
I have gmail and exchange in push autosync, plus 2 screens of widgets that refresh (weather, news, calendar and mail), 15 minutes of calls, some texts, news reading, picture taking and viewing. Screen was on for 3 hours in this 16.5 hour period.

Unless you are chilling around all day a foot away from a fireplace, this is not normal. It means something is constantly running on the phone and is using the CPU heavily. If you screen is on, it also heats up. Lower screen brightness if you have the screen on for long periods of time.
and if it is rogue apps running in the background, eating CPU cycles - do a factory reset as someone already suggested, and then set up your phone anew, carefully avoiding CRAPWARE and BLOATWARE services and apps.

Started with a fresh load this morning at 5.30 am, working continously with my SGSII, downloaded apps etc., twice clearing with android booster still half batt left when typing this.....
Brilliant, isn't it ?
My HD2 would not make THAT.

looks pretty normal, but you should post your screen-on time to give a better idea to tell your usage for sure. 3-4 hours of screen time and that's normal.

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?

What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted

Do you have data off?

How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

what ver are you using if 2.3.4 the battery issue is fix.

I get 3 /4 bars, at school right new and yea some times I get nothing, especial ly during the subway ruse which is an hour
Sent from my R800i using XDA App

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

xiEvo is correct and I've read a lot of good stuff regarding battery life with 2.3.4. I can only begin to imagine what kind of battery life I'll have once I get that update.

Honestly I had the best battery life with 2.3.2, IDK why.

My advice, get Tasker to disable mobile data and WiFi when screen is off. Disable Google Now. Disable NFC. Disable GPS until you actually use it. Enjoy your 5+ hour screen on battery life.

Why the hell does the Nexus consume soooo much battery ? I have turned most of the stuff off but you dont get any Google Now, emails etc dont work correctly, - totally useless.
My S2 is better than this.

And? Most people don't seem to get this: Say your battery depletes 1% for every 3 minutes you have the screen on, that's 300 minutes, or 5 hours, of screen time. Which is more than acceptable.

Yeah def better than the gnex which was rather good too. I took my phone off of charge @ 7:20am and put it on charge when it had 4% left @ 1:30am. So pretty much lasted 18 hours with medium use.

Regarding battery life

Hello
Long time Hero user who switched to blackberry and now back to android. I've had note 2 for 3 months now and I'm actually disappointed from its battery level. Not that its not enough. .it just didnt live up to its expectations
Through constant whatsapp messaging only (today) 40% drained in 7-8 hours. . I know its a long time but shouldn't it last longer or is 3g that much of a battery usage?
Also does charging with a 2a non official charger might affect my battery? And with the time frames I have available for charging I can never get a full charge. .does that matter?
And is pile stocking on applications and games affecting my battery? Even if they are not open? (Currently using go power master for that)

Show some screen shots of the battery graph. I was just wondering what was your screen time to get a better idea.

Sent from my GT-N7100 using xda premium

You can click on that little chart to see a more detailed view of your battery consumption. Your battery life is a bit on the short side (compared to mine at least), Im guessing the screen is the culprit. Do you have brightness all the way down? How much screen time does the phone get?

@Shei77
For me is battery consumption pretty fine. It depends of course what I am doing with the phone through the day. For example yesterday after whole day "playing" with phone from time to time I had around 70%. I am chargin it when I go to sleep because still if I have in the morning 30-50% it wont make it through day when I dont have option to charge it. Just to add, I have Wifi and GPS always on.

If constant messaging for 7-8 hours means the screen being on for 7ish hours, you have ridiculously good battery life at 40 percent..

I'd say your battery life is fine, im guessing maybe even better than mine. Im doing 6h 37m right now with 69% left, H+/3G always on, with moderate screen time and a bit of gaming.

Huh..what about charging?
Also any tips for extending? Ram keeps filling up after some time..is it cause I have a lot of applications?

As shown from your screenshot your phone signals are really bad. That might be contributing to the drain of the battery.

I think your battery life is fine :good: Usually with my note 2 i can do 4 display hours and 1 day or more of battery life. 3g/h+ always on, lumi 50% all sync on, calls, gaming and web.

This is the current on screen which is a few hours after the first screenshots
What can I do about signals? And if I have a lot of apps do they consume battery through background?
Sent from my GT-N7100 using xda premium

Really, your battery life isn't that bad. The 7 or so screen time hours you'll get if that continues, is pretty good!
And to your other questions, charger type doesn't affect battery performance. Charging time should take around 2,5 hours from 0 to 100, if you're far away from that, the charger might be at fault.

Charging usually takes 3 hours for a full charge and according to my charging current its using 1698mah
Sent from my GT-N7100 using xda premium

I updated it just a couple of days ago I need an expert opinion on how good my battery's time is.

^No offence, but without screen on time a battery stats is just meaningless!
So kindly post your 'Screen on' time.
@shei77: You're on H+ and you're having almost three hours screen on time, with 60 odd percent left. That is very good battery life.
'Swyped' from my GT-N7100

Maybe a bit OT, but what I have noticed is that when the phone reports fully charged, Elixir widget still displays 1600mA being charged into the device? Also, when the battery is full at 100%, the phone is still pretty warm! I don;t remember my HTC did that? It was warm, but when it reached 100% it cooled down and was not hot anymore... I tend to keep phone in charger in the evening because I use wifi hotspot....

My battery life is awesome I'm on cm 10.1 rom with uneak kernel, cm 10.1 is smooth and great performance and great on battery life,
I have attached a screen shot of battery stats...

Dude.. My phone was on 60 percent at 6pm once when I slept... Next morning at seven it was off... Wifi off data off.. All **** off... I dint even get a call or msg... Definitely not 1 percent I guess...

If I leave data and WiFi off, about 2% to 10% but that isn't usual. When I am home, I leave WiFi on and that gets my currents and YouTube video preloaded. 15% to 20% Max. I rarely leave it to charge overnight.

I kill all apps, turn of data, wifi and etc, still nothing...
BATTERY STATUS - messaging use 84% of battery... wtf ?

To all of you having problems with battery drain, you should know that last Google Maps update messed up the deep sleep state of the system.
I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.
I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.
With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Android System" or "Google Services".
Before update I had around 3% battery drain over night(around 8 hours) with WiFi.
Hope this helps.
:fingers-crossed:

As a battery life druggie, I get 1% max. Regardless rom. Usually wifi off and 2g data on. (wifi on is bad for HUMAN DEEP SLEEP).
A not sure useful or not hint, set pm.sleep_mode=1 in your build.prop
Disable everything you can think of. Wifi, gps etc.
Uninstall bloatwares, replace with downloadable ones, use greenify to freeze them.
