Looks like you have an app in the background that causes your problems and dont let your phone to deep sleep

i figured it was something along that line...since deep sleep takes up so little. but i thought the screen is the biggest waster, any app that is simply in the background shoudlnt deplete my battery so fast.... i have to charge 3 times a day...
BUT HOW DO I FIX THIS..

Yes, but the screen cant eat your whole battery in 2h ... i have ARHD 6.1.0 and stock kernel and my screen time is about (minimal) 4h with autobrightness

I am not sure what apps and mods you are running, but what i would do is:
-install android wall from HERE to block some useless apps to access the internet (this app has a widget too so you can enable and disable the firewall whenever you want)
-use more the task manager to track what apps are running
-follow this instructions (the one you think could help)
-and disable some unneeded apps here
edit: almost forget, dont use any task killer, they are useless and causing more battery drain ... ill quote one of the best kernel devloper we have on the HOX so far, faux123: "Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close)."

Cyanogen Mod 7.2 RC3 Battery Drain

I know this has probably been answered somewhere before but I couldn't find a good answer. I have lost 10% battery in an hour and a half with no use other than stand by. Any tweaks within the Cyanogen settings I can make to help at all?

Did you add any kind of task killer on your phone to prevent things from running in the background all the time?

I have advanced task killer but its just an app. Its not running all the time.

And I let my battery drain all the way to 0 and charged fully from scratch with it off. It lost about 20 in an hour add opposed to 10 today.

You can set it to auto-kill. I'm actually kinda surprised you're having a lot of battery problems with RC3 though, you may just need to wait a few days for everything to stable out. When we get new ROMs we like to play with them a lot and drain the battery! I would also suggest using auto-brightness to prevent excessive screen power usage.

That's not normal for idle at all. Is the battery old and just wearing out? if it's fairly fresh (< 1 year) then it should be fine. Try betterbattery stats to see if the phone is keeping wakelocks and also CPU spy will let you know if your phone is reaching the deep sleep state.

I have the brightness not on auto because it was picking up the light right, but it's turned down pretty low. I'm about to post the results of the battery info, and those 2 apps... They're in the below zip folder...

I unplugged my phone about a half hour ago and have been using it a decent amount. Went from 100 to 80 in that time.

the first ~10-20% is not always that accurate.

I don't know that drain just kills me lol.

Today was 11 % in 5 minutes. This I'd crazy.

Huge Battery Drain Issues

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.

Install perseis kernel...dont try to install cheap apps or games from playstore...beacause they run even after closing it in the background...try to deactivate your 3g network and wlan ...btw.. try tge app 3g manager...it deactivates your 3g mobile network when you lock the phone.. and reactivate it when you unlock the phone..it might help you.

I think 1% per hour is normal because the use to monitor the network

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

Any ways to save battery other than settings?

I really like how my settings are. Sync settings are minimal...but its been off the charger for 3.5 hours with moderate use and its at 76%....im looking for how to undervolt (not underclock) or any battery saving tweaks.
Also...im on synergy rom and cant change the setting so there is no LTE..why? And quck question...is there a key strock to get to recovery...new here
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Turn off the Location access, and dim the screen as much as you like... I just got 36hrs with 3hr screen time with only those changes... To undervolt, you need to be running a custom kernel, and use a tool like SetCPU, Voltage Control, or KTweaker if the kernel is KT... To get into recovery, use the advanced power menu, or while it's off, Vol Up + Home + Power... Check your APN settings for LTE...
I've found that undervolting is a pain, and doesn't save me anymore battery than stock voltages... Mess around with it and decide...

I'm sure it has some sort of battery use, it's always looking for motion... Whether turning it off or not will help a noticeable amount, I'm really not sure, it's a TouchWiz feature, I haven't ran a TouchWiz ROM the entire life of my phone...
Any TouchWiz junkies out there who have noticed a difference turning it off?

find and eliminate wake locks. disable bloat apps. run a good light rom with battery saving kernal. turn off what you dont need. thats all really. if your battery is dying fast find whats keeping your phonw awake and do something about it. I can go to bed with phone at 100 and wake up 8 hours later at 99. also go to bed 50 and wake up 49 etc. you should expect the same. on 3g I get at least 5 hours of screen if im heavily using all day. but battery life is up to you. you want to be minimalist like me you can expect similar results.

You can dial *#0011# then hit Menu > Wi-Fi Settings and make sure the WiFi sleep policy is enabled. Every time your phone sleeps, WiFi is disabled and you have to reconnect, but it does help on battery life.

I dont think it does. uses battery to turn on and off the wifi. just leave it on. ny rom is wicked v8 and intergalactic 2.5 kernal. weird combo I guess. but it just works for now

I squeezed 7 hours display (18+ hours standby) on a single charge with auto brightness on and LTE and sync on all the time. Routinely I get 5+. I would say, get a good rom n kernel combination (only way to know is to try out).
Are you using Google+ and/or facebook?

Battery Drain bad

Hey guys, I've been using my nexus 7 and one thing I noticed is that my standby for the tablet is bad like I would leave it on my table for an hour and it drains about 5 percent. I have a droid DNA and with that I usually lose ,maybe 1-2% an hour on standby while connected to WiFi. Any ideas? Also I'm using clean ROM 1.7 and elemental kernal 1.4

The usual reponse....
install one of the available Battery apps which track wake locks etc and then optimize your settings or switch to another Kernel/ROM

Which app do you recommend?

This one seems good - https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en_GB

I am in utter AWE about the idle drain. It's almost non-existent. Carbon Rom, default kernel, with Greenify and AutoStarts, the usual tweaks. Result:
Two percent a day is "doable"
