My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.
Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.
Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.
Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??
You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.
Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.

CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?

But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?

I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?
Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.
I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note
I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.
Does setting an alarm overnight cause a lot of battery drain??? plus i use "hide my text" app, also known as "invisible texts" app. Is that the reason for this battery drain even when the wifi is off and with 10 texts n no calls, my phone's battery goes down by 40% in 8hours....is that normal?? I have nexus s 9023.
In the "battery use" option it shows that the phone display is consuming 33%, I have auto-brightness ON, and 30seconds screen On time. and not using a live wallpaper.
Cell standby shows 10% battery usage. Auto n background sync is also off.
Currently it shows 7hours 1min 14s on84% battery.
the current android version is 2.3.6
also when i was using a task killer, it showed that new apps started up by themselves even when the wifi was off, every time i opened the app killer it would show a list of working app =S then i thought that the task killer might be causing the battery drain so i uninstalled it.
kindlyyy HELPPPP!!!
Better Battery Stats, search for the .apk in xda. It will likely reveal your mystery wakelock.
I've got brilliant screen off battery life on my SGS4, but soon as I start using the phone the battery just plummets.
I took my phone off charge, went to the bus stop, started at 100% and finished on 89%. Total off charge time 19m, screen on 12m. That's 1% every 2 minutes!
I'm sure it's not a background task, my phone goes into deep sleep most of the time. Checked CPU usage and nothing is up, got brightness to lowest and all extra features off and power saving on. I had 70% left yesterday after being nearly asleep for 13hr.
Using Golden Eye 8.0 ROM. XXUDMI1 bases with Adam kernel 1.6 and baseband XXUDMG5. I've used other ROMs to no change.
Went down by 7% just writing this!
Down to 60% battery after 1hr20min off charge which 1hr screen on
Hi,
New to the Nexus 6p. I can't figure this out - when I am at home on wifi, my phone barely uses battery and Android System "keep awake" is low. When I'm at work, the battery drains much faster, and I notice in both Gsam and the native battery settings that Android System is kept awake for an inordinate amount of time, thus draining the battery at about 8% an hour, even w very limited screen use.
What would cause Android System to stay awake like this? Is there any way to identify the specific thing causing the problem?
Thanks.
Here's screen shots to help.
One more...
I have seen better battery stats than mine. I don't know If something's wrong with my device (I have warranty tho so if it is, I can replace it)
I noticed that wifi is at the top of the list so I'm not sure what's going on.
I have greenify set for facebook because It destroys any battery. Also I disabled my location in case it was google now.
Accubattery shows 55% consumption while screen on (3h 29 SOT) while 38% of the battery gone while the screen is off (80% of that time is in deep sleep)
In the android's battery stats, wifi appears above screen in battery consumption.
Overall it's 16h 45 min of total battery life at 5% battery left.
I have seen 5h, 7h SOT so I don't exactly know what to expect.
I really need a hand because I can't let this pass if it's really a battery issue.
Thanks in advance.
Maybe you want to post a BBS log in this thread https://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884 to get proper help.

Nobody knows which device, bootloader status, dual sim, WiFi, apps, settings, rom etc. you are using. So please be so kind and provide these informations.
Also a full cycle of better battery stats is useful with all screens provided.
And as bullfinch110 said: there are threads(older) with battery tips
I'm sorry. I couldn't find a way to upload screens without external links and xda wouldn't let me.
Its xt1641, dual sim but i've only charged it with one.
Stock 6.0.1 Rom
Locked bootloader
Wifi is always on in that cycle. I've disabled today "enable wifi on deepsleep" to see what's up
I've also restored network settings.
