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.

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?

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.

S3 Battery Drain

Hi, I had my galaxy S3 from Rogers for almost 1 year and the battery drains like crazy!! When I first got the phone the battery life was ok. It lasted 1 full day (with the settings auto brightness, wifi usually on [when not in wifi area, using LTE], vibrate only, power saving on and snyc on. I turned off gps, bluetooth, location services, and motion). About 6 months ago I dropped the phone in water :S and I got it repaired. The phone battery life was still about 1 full day (with the same setting as above except when I'm not in a wifi area I use 4G to save battery life). After that every month the battery life seems to get worse from 1 full day to about half a day :S. After doing alittle research (this was around May/June) I found out Facebook was killing my battery so I stop using it on my phone then my battery got better (to about 3/4 of a day). But after that in July and August the battery life got really really bad, it will probably only last 5-6hrs. I honestly don't know what is wrong with it now. Is the water damage the problem with my battery drainage?
I'm running 4.1.2, never rooted and I'm running Nova launcher too.

Get better battery stats or gsam battery monitor to rule out a rogue app(s) first...

Maybe the battery cells are dying out?

I leave mine on auto brightness too, I still get around 24 hours on a charge, and between 5 and 6 hours of screen on time. My phone is only about 3½ months old though... Could be the battery??

Is it the original charger that came with the phone? And are u charging it from the wall or pc??

Ya I am using the original charger and original cable.. using ac supply, with plugged in wall...
The thing is if I reset my device ( which I have done 2-3 times) and after that, watching video/playing games/ internet surfing etc. With the charger plugged in, works fine... I mean it charges my phone battery fine. Battery is new. Checked its condition with battery monitor pro... it states its good.
But after a couple of months after resetting, I face the problem of slow charging, with my phone in use while plugged in... did a lot of search but didnt help out. Cleared dalvik and other cache.... nothing seems to be working.

2nd time g3 battery died over night

Usually i charge my phone when i get home and unplug it when its at 100 before i go to bed. When i wake up its at about 90-100 battery life. Today it was completely dead and a couple days before. Have no idea what caused it but has anyone had that happen?

Okay but will it show whats wacklocking my device after i turn it back on after being dead because i know gsam battery restarts and shows no history of use after u turn it back on

I had a similar issue. I charge at 100% before bed. Often wake up at 99 or 100%. The other day it was just above 30%. The problem was Boat Browser, which I left windows active/open.

Odd my battery died again I always make sure I have nothing running in the background.

Use an app like 'better battery stats', it will show you what's eating up your battery.

Does it die during the day as well?
I'm just curious, why would you unplug it at night before you go to bed? Wouldn't you want a fully charged phone for the next day?

Because lg has amazing idle time I usaly wake up and there would be a 3-6% drain from 100%

My phone stays at 100% for hours of use,so my guess is you are losing out on a few more hours of battery life during the day.

[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

Sleep tracking

I am about to buy a Zenwatch, and was wondering whether any of you has tried sleep tracking. I know that "Sleep as Android" supports Android Wear. How does it work with the Zenwatch?

It works OK but doesn't half chew through the battery - around 10% per hour.

I just installed and setup 'Sleep as Android' to test out with my zenwatch tonight. I'll note the battery percentages and such before and after... I am interested to see what it states...
BEFORE:
So i got a 93% charge on my watch prior to going to bed, plugged my phone in and placed it on the bed as well... once i got in bed i put my zenwatch into theater mode to conserve battery.
AFTER:
Six hours later i woke up and had about 36% battery life... so the sleep as android app kills some battery... but at the same time it also provides alot of cool data...
I will probably continue to charge my phone before bed and see how i can try to improve my sleep patterns, but probably wont mess with it again after that...
its a shame it uses soo much battery...

Odd it drains so much. I use the same app all week. Typically go to bed with battery at 60% or so and wake up with 35-40% and that's on always on turned off not in theatre mode.

I've only used it with Sleep once since I got the watch earlier this week. I had just over 50% battery when I woke up 8hrs later.

I hear that the same app drains much less on the Moto360 and SW3. So it might be only a matter of time...

Reports are that it drains just as much as the moto 360 due to both of them not supporting sensor batching, or so i've been told by the sleep as android dev (who's advice for using the watch for SaA alarm but not sleep tracking was to turn on BT when I start sleeping then turn it back on )

I use sleep as android every night, and it does drain my battery, but my battery seems to run down a lot anyway, I have to charge it at least twice a day. And the app works with the watch perfectly!
