I have a very wierd problem that when I put my note 2 into power saver mode it drains battery although in pwersaver settings everything is marked and green. Can anyone know why is this?
I go to sleep 8 9 hours normal mode battery drains 3 4 % in normal mode wit b wifi on. I turned off wifi turned power saver and tried it for 3 times when I sleep 8 9 hours when I wake up 10% of battery is gone, no applications active or in background.

If you turned WiFi off it is probably using radio which uses more power.

today while using my phone the battery ran flat, no biggie, but when i charge it the red led glows until it starts up, normal boot but when it finishes it shows that it has zero percent battery and after a minute it turns off and the red LED comes back, and repeats.
I am currently using P.A.C man rom 18.0
Using Nova kernel
Can some one please help me?

well let see how it goes
Battery doesn't show what apps are running
All my battery displays is Screen,Device Idle, and Wifi
It shows no other third party app that is running. This can only be temporarily fixed by rebooting my Note 2. Which then it happens again after full charging the device.
Is there a fix to this? I barely got it and it is bugging the crap out of me
Same here thought it was so weird

This happen to mine too.. when i turn off auto sync in Settings>Data Usage>Left menu then turn off Auto sync data.. But good in battery saving..
My Note 2 just started doing this as well. Settings> Battery and all it shows is the overall usage graph and Android OS 100%. If I click on Android OS it shows 298 days of usage. I tried deleting the batterystats.bin file/full charge/reboot etc but that didn't work.
Anyone have any ideas?

Fixed it.
Ran it down until it turned off/died.
Plugged in stock charger.
Once fully charged..green LED...powered on.
Booted into CWM from restart menu.
Wiped both caches.
Wiped battery stats.
Reboot.
Unplug from charger while at 100%.
Thought I followed these steps before but apparently I didn't.
Back to normal.

My phone does this when cpu power saving is on. Turn it off and it's fixed.

I've had battery issues ever since I bought my Note 2. I tried buying a new battery, custom ROM (ARHD 13.0), custom kernel (RedPill). I get a drain of 2% per hour in standby, and 17.2 percent (!) per hour in normal usage, not even heavy gaming. The screenshots are for continuous usage. I got rid of wakelocks, the AudioOut2 one by Viber, the NetworkStatusMonitor through maps. (these were 80% of all partial wakelocks)
I usually have sync enabled, 4 email accounts for once in four hours, and Facebook, and Samsung backup. That's it. I'm on an EDGE network, with network set to GSM only, WiFi only on when required.
I have ~83% Deep Sleep when I don't touch the phone overnight.
All motions/smart *s are disabled.
I don't know what else to do. My wakelocks show completely normal values. (I'll upload some when I get to unused time)

Almost 90% sleep. But still draining 10% in 10 hours of no use.
Could someone help me debug this drain?
Sent from my GT-N7100 using xda premium
If you are complaining about 10% drain over 10 hours (1% drain an hour) then you are very mistaken about how a mobile phone works.
There's nothing wrong here I can see.
I've seen people report less than 3% drain overnight. And 2-3% per hour of use. 17% an hour? Too much.
Edit: I know cell phones consume battery because they're wirelessly connected to and monitoring networks and that they need battery to receive and process packets of data and other stuff while not being used, if that's what you mean.

0 over 6 hours so he is correct

Is your wifi power save mode on or off?
!!
I have the same excact problem. Just bought it and the battery drains so faaaaaaaaast !!!...
The screenshots in my first and second posts are with WiFi on, connected but never searching. In the third post, WiFi was off the whole time.
Edit: Power saving was off both times. There's a noticeable FPS drop with power saving that I hate.

Please get Better Battery Stats, and post your screenshots over at least an hour of no use, and 30 minutes of use. I might be able to help. (I'll try, anyway).

Are you on an AOSP/AOKP/CM based ROM? I understand that battery will be significantly better on those than a Sammy based ROM because of Sammy bloatware, but I'm unwilling to lose all the perks. Although the figures I said people have are all for people on either stock with custom kernel, ARHD, or ARHD with a custom kernel.
Edit: I also took care to take these figures from this forum from people who had a few syncs/online services enabled.

Not anymore. Perseus kernel with Greenifier = 0.3% drain an hour, and 5% per hour of use.

This is screen shots
While idle and all connectivity off except SMS & phone calls I lose 1.7%/h is this normal?
Sent from my GT-I9192 using XDA Premium 4 mobile app
I'd say yes. As I can see from your Screenshots you were two times disconnected from any cellular network. Remember this causes more battery usage (but no drain at all), because the phone is searching for network consistently.
Both, the 1.7/h as well as your screens are totally okay.
But I read some where that I can bring down usafe to less than 1 %
I have disabled all samsung apps and use silvui kernel
I have note 2014 unrooted and battery loss per hour is far less
Sent from my GT-I9192 using XDA Premium 4 mobile app
That's right search forum for threads with this topic. You said this battery usage appears at idle state. The second screen isn't idle at all because you are using your device (but you have no wake locks which is pretty good btw). I'm sure you reach less than 1%/h when you don't use your device. You can also install better battery stats to monitor what's using energy and freeze it.
Did you also activated energy saving? Try this in addition to offline mode and check with BBS the over night consumption. I'm pretty sure it's below 1.
Last night battery dropped from 43% to 35% in 3 hours while I was sleeping thats too much ... 3g wifi bt off

Were the many Apps in multitasking? Try clearing RAM, reboot and all energy saving techniques.
Try to post idle stats

Install better battery stats or wakelock detector
Then charge your phone at full clean all ram and leave it untouched while you sleep and post your stats right when you start using your phone

Tell us what consumes battery most. Do you run your phone with two SIMs?
I think is the radio and cpu
