Galaxy Note II GT-N7100 battery problem

Hi guys, I just got my galaxy note II for like 2 weeks ago. And i've noticed a problem about my phone.
My galaxy note II will drain the battery for like more than 20% ( 20%-25% ) while its in idle. Which means after i fully charged my phone, i unplugged the charger and i used it for awhile more like it was left 92% before i slept. Then the next day when i woke up i noticed that my phone's battery drained about 20++%, it became 79% (i slept for 8-9 hours). I didnt leave it with wifi on. I just left it with 3G & power saving on!!!! This is a serious problem, i mean how is it possible to drain for 20% just for around 9 hours of sleep.
And one more question, how long does your galaxy note II battery last after a full charge with you playing checking the phone for message once for almost every 20 mins?
Normally i woke up around 9am for work and by the time i reach home at night around 12am. It still has around 30% of battery. But today, this strange thing happened. I unplugged my phone around 9.30 am. Starting of the day was okay, it was normal. But right after it was reduced to 60%, the battery started to drain faster. By 8.30am it was already left 25%.
:crying:
GUYS HELP PLEASE!!! AS IM NEW HERE. REALLY REALLY NEED A SUGGESTION ABOUT WHAT TO DO TO MY PHONE.
:crying:

Yes the battery does drain even as you sleep. Keeping 3G on actually drains more than Wifi. So if you really want to preserve your battery overnight, turn off your mobile data totally. It is somewhat an annoyance that you can't choose between 2G/3G like you do with iPhone. If you still want that connectivity, leave wifi on instead of mobile data.Give it a try for one night and see how it goes.
Are you using any power saving apps?

I just tried again last night and it drains from 100% to 81% from 8 hours of sleep? Is it really normal?
I am using this app callee "cpu spy". Over 8 hours of state time. Only 5 and a half hour my phone is actually in deep sleep. 200mhz for almost nearly 2 hours. And the rest go to 1000mhz and 1400mhz. Do you understand what it means? I dont. Can you please explain?
And im not using any battery saving app. Any suggestions?

Post some screenshots of your battery usage.

Strange, for me the battery is quite long lasting. What application is draining your battery?
Attached my screen shoot.
Sorry for the chinese menu.

Follow the link in my sig towards How to flash a custom rom (no i am not asking u to flash one). U will find one tab for useful links. That thread can help you debug your issue as well as suggest probable solutions.

You can change between 2g and 3g.
More settings > mobile network. GSM is 2g and wcdma is 3g.

Op have you installed viber by any chance? This app drained my battery quickly even when I am not using it.

[Q] Battery Drain Over Night

When I had my Note 1, for some reason over night it would drain like 50% of the battery, no idea why so I sold it. When I has my iPhone the most it ever drained over night was about 5%, 4 and 5. Last night my Note 2 drained about 12%, the only App open was the Alarm.
I know 12% isn't anything major, but with the problems I had with the Note 1 I just don't want to wake up have been fully charged the night before and then have to charge in order to even use it the next day. I need an alarm set or I won't wake up to go to work.
What is the best way to keep battery life over night but still have an alarm set?

Install betterbatterystats from playstore to keep a check on Battery hogging useless apps.
YOu dont need to keep the Alarm open in the background exclusively. When you set an alarm,it would be there untill you disable it manually.
12% overnight is a bit more than normal. For a 6-7 hours, battery drain should not be more than 5-6% when the screen is off and phone goes into Deep Sleep mode.

Why not just charge it over night so that you always wake up with 100% :S

Cause the charge cable is short and doesn't reach to a sensible spot for me to be able to quickly turn the alarm off before it wakes the rest of the house up!
I'll do a few more test runs before I install any battery apps, from what I have seen so far most apps actually mess up the battery for me. That Battery Widget Reborn on my Nexus 7 takes the charge time from about 2-3 hours to 7-8. And one's I've used in the past actually drain it quicker.

Woah...never experienced that mate..did you turn off wifi?? For me 5 hours of sleep will only decrease 1 -2 %... stock rom dll7... check your apps in the background

Hit thanks if you love your phone =)

Ah that's a fair reason
I left mine off charge over night so I could compare. I left everything on as per my usual day (WiFi, GPS, auto sync) and had an alarm set.
I lost about 12% as well

Betterbatterystats is not an "battery" app. Is an app the monitors your phone and reports misbehaving apps or partial and kernel wakelocks.
It has nothing to do with increasing battery charge time.
Search it.

Thanks for doing that I turned my GPS off last night and results were a lot better. But awesome of you to try that

May have to give it a go if the problem persists, but for 10% battery it's not major. But thanks for clearing that up!

The only thing that you need to do is turn off data connections and wifi. This way I lose 1-2% battery life over night.

Well Android's ecosystem is made in this way. Literally you can't do anything. If an app or a couple of apps think that they need to run at a certain time, then they WILL run, it's as simple as that. No app is there to stop it, but yes some apps are there to make it worse, so stay away from them. One night you will notice 5% drain, the other night 10%, with same exact settings.
Still try to turn off Data/3G at night, if you don't need it. And get used with it

Abnormal Battery Drain ?

So every night before sleeping I turn Data/ Wifi off, Past few nights ive noticed there has been a 12-15% drain in 8-9 hours.
Battery before sleeping 30%(data/wifi off)
Battery 9 hours later 15%
Stock 4.2.2
No Intense Background apps.
Is this normal ?? I don't think 4.1.1 had such battery drain with screen off and no data/wifi.
Thanks,

so u basically(roughly ) have 1% drop an hour? thats pretty damn good if you ask me
mine is usually 10 hours with intense use and 30 hours with minimal use eg: at work

That's normal at around 30% battery left. Once it reaches 30 and below it really would drain that much even without doing anything. But if you start with 95% percent and overnight drain of 15% with all off, then there is a problem somewhere. I usually have overnight drain of 3% for 8 hours.

Thanks for the reply buddy, 1.5% an hour seems higher, but as mrm43 said i think its the cause.

Thanks for your reply, I had a feeling about what you just said. But I don't recall this happening before, I could be wrong. Will charge up and test tonight and post results.
Also, I'm noticing my phone getting warm past 1 week while normal usage( Web surfin+music) area behind the camera.

So just to post back, I charged the phone upto 85% and turned off Data and Wifi, Woke up 8 and half hours later and the battery was 79%. Which is ok I guess, assuming only cell radio was on.

Battery drain at idle

I'm losing around 1% of battery every 2 hours when I leave my tablet sitting sitting idle with wifi on. Is this the case for most people?

I'll admit I don't my N7 yet, but that seems like over a week in standby. Not too shabby.

That sounds pretty good

That could be about right. Once I finished setting everything up Saturday I gave it a full charge. Between Saturday night and last night (Monday) I had about 1h 45m of screen on time from using it and was down to just 67% after nearly 48 hours of standby plus some good screen on time.

I took mine off charge at ~6:00AM surfed the web for ~10mins. I left it idle for ~10 hours and it was at 94%. BBS says 0.5%/hour.

I seem to be losing about 2% per hour at idle, though I'm monitoring it at the moment.
Last night (over ~8 hours), I dipped form 64% to 51%, today (over ~9 hours) from 48% to 33% This all at idle. The biggest culprit for usage seems to have been Google Play Services with a keep awake of around 50% (or 12 hours over a 24 hour period). Made some changes to settings and what to sync, am charging again, and will see what will happen. All up, 32 hours with maybe 3 hours of screen time (1.5 of that being Netflix) used 67% of the juice.
Currently bone stock. Contemplating unlocking/rooting though, since custom ROMs have done wonders for my phone's battery drain (from ~5%-ish per hour stock to around 1.8% per hour)

[Q] How is your standby time battery life?

I went to sleep with 100% and woke up with 93%. I left WiFi on, I'm sure that if I turned it off it would improve but I was curious how it would hold up.
Wondering if anyone has tips for improving standby time battery life.

Are you seriously thinking that 7% while you slept overnight is some kind of problem?

Arround 1-2% overnight(wifi on, but with "Keep wi-fi on during sleep" on Never)

Yes.
I can compare that to iPad mini and Windows Phone ( Nokia N925 and N520). 1-2 % with GMS/LTE on.

Same Here
Yes I am also facing the same problem. Terrible battery time. I charged my Tablet yesterday and pulled it out at 100% at 10pm. I put it on Airplane mode and went to sleep. When I woke up today at 6am the battery was showing 70%. It ate 30% at night doing what? I am very disappointed. On Kitkat 4.4.4 I never had such terrible battery performance.

Same here, on a fresh Lollipop install, wifi turned off during sleep, bluetooth always on, and with only a few apps downloaded. Last night I unplugged my tablet and it was still 100% this morning. Been like this since I flashed stock Lollipop after a full wipe.
On 4.4.4 with a lot more downloaded apps I was getting abysmal standby time. The confounding thing was, power use during standby would be fine for a couple days, then turn all to heck, like to 20% plus per night, wifi would turn on by itself during standby and stay on. When I cleared the caches it would go back to being OK for a couple days, then turn bad again. I had even turned off automatic syncing on every app that I was able to do so.
Couldn't figure out which app(s) were the culprit for the life of me. So now I am adding new potentially problematic app back on at a time to see if I can figure it out.

Here is what happened today. Turned off charging at 100% at 10:45pm and woke up at 9 am to 70% on airplane mode. Please tell me that others are facing the same problem!

That does seem pretty weird. This is my N7 since yesterday morning:

Thats not bad at all. I dont know why mine is doing this. What do you guys suggest i do?

I was on jellybean before lollipop and it had waaaayyy better battery life
