Battery draining way to fast

I woke up at 7:00am phone fully charged.
Now is 10:40am and its almost at 59%??!! This wasn't happening before... I wonder what is running at the background that consumes so much battery. I haven't used the phone Mich either... Compared to days before where I even used it more including the camera... And never drain this quick.
Help me here figure out what happened.
Thank you.

Check and let me if this helps ....
Go to settings --- battery --- open apps individually and restrict background data of apps which you do not want to use data while not in use.
Also, keep screen brightness to 50%- 70% max.
Switch off data when not required.

Battery problems

Hello there,
I noticed that my battery really doesn't last long. It's been 100% full and now, 4 1/2 hours later, there are only 6% left. The weird thing about that is that I did not really used it during that time. WLAN has been turned on over that time, display was really dark, no backlight notifications or anything. Has anyone any idea how to fix this? (LG P940)

can you give more info
can you give more info? info like- which android, how many mah (ex: 2000,1000). give that and i may be able to help you,...
Would be really awesome! Android version is 4.2.2, battery has about 1500mah (think it's 1540) and I'm using the cyanogenmod kernel. Do you need any more information?

Thats not really much of a battery for the hardware,.. how old is it? Is this a recent problem, and when did you flash to CyanogenMod ?
To me it sounds like something is draining the battery pretty hard. Is the Wi-fi signal stable? Any processes under Apps>All, using excessive memory?
To me it sounds like you are having wifi/gps/bluetooth on all time, and if not, you should close ALL apps next time. Some running apps on your background could even drown your battery from 100% to 0% in less than 2 hours. Big apps or games cause the most trouble

If this phone/battery is more than one and half year old, this could be just battery dying, like mine (LG P920, 2 years old, 1500mAh) is dying right now.
It can't last more than 6 hours lately, so i bought a new one.
A li-ion battery (standard models) just can handle frome 300 to 500 charging cycles, thus if tou charge your phone every day, battery life has about 18 months lifetime.
After, it just dies, more or less slowly.
Thank you all so far.
Bought the phone 1/2 year ago so this can't really be the problem. The battery has never been great but got worse about a month ago. I flashed it about 2 weeks ago and this didn't seem to influence the battery.
I always keep GPS and Bluetooth turned off (only turning GPS on when I go running, but I never noticed that this influences the battery either) and Wi-fi is pretty stable. As I heard that Wi-fi is really bad for the battery I tried turning it off as much as possible and so far it seems a bit better.
I also took a look at how much memory the apps use and saw that Facebook, Kingsoft Office and Whatsapp really need a lot. I think I will uninstall Facebook and KS Office then and see if this helps.

I presume you bought it new ("and sealed")?
Maps used to be a big problem for me running in the background. See which apps use Maps.
Yep, I got it completely new.
Okay, I'll check that, thanks.

Also problem with battery
I had a similar problem, my battery got "sick" after I used my phone as a GPS during 2 or 3 days. the phone was quit warm during the navigation. After that The battery life was reduced from around a day to 9-10 hours. In addition when battery is around 20%, the phone just shut down due low-battery and as soon I turn it on, as soon it turns off!
The solution was to buy a new battery, but that is odd that using the phone as GPS navigator damages the battery so badly!
Btw, my phone is a HTC desire w/ Android 4.2
yah now i may be able to help you, download the antutu battery saver app from google (it requires root) it is a really good app and helped he last
my battery from 3 hrs to 7 1/2 hrs. if you don't have root access, then it is a prob. if you don't have, tell me and i will give you another solution which
does not require root
Thanks man, I just installed it, will write tomorrow how useful this App is.

Ruined baterry

If the baterry drains super fast does it mean its broken and should I buy a new one ?
Sent from my GT-I9100 using Tapatalk
It could possibly be a problem with the batttery.
Are there any wakelocks occuring? Do you have a lot of stuff running in the background? Does the rom have any battery problems?
Without checking all the above, we can't really help you

Do you have Skype installed? That has been causing lots of battery issues lately.
Google know about the issue and are working to fix it.
Are you running a custom ROM? Try wiping the cache partition.

First week I used Moto G with one sim and battery lasted for 16-20 hours. I was expecting more.
Surprisingly, after I put the 2nd sim I am getting 24-30 hours. It looks unlikely its due to having 2 sims, maybe the battery required some charging, discharging cycles before giving its intended capacity.
Hey can you post ur battery screen shots with dual Sim

EDIT: upgrade on battery life 2days 21hours on battery, 3h on screen time. 18% battery left. This is after third battery charge. I am more than happy with the result. With custom ROM, some kernel improvements, Greenify it should last 4 days with 4h on screen time without a doubt.

That ain't hard to achieve actually, mine right now is on 2d 15h, 5h on SoT. The best I could get was almost 10h screentime on a single day hard usage.

[Q] Xposed framework battery drainage

Hi i have a nexus 5 rooted on the stock rom and when i install the xposed frame work i have significant idle drain even when i have no moduels enabled. if any one knows what could be causing this please let me know thanks.
What do the battery stats show?
Sent from my Nexus 5 using XDA Premium 4 mobile app
its the same as when i dont have it enabled. only with alot more battery drain not really much out of the ordianary in the battery stats
Well I would remove the framework and see if it goes back to normal. It might be a coincidence, you could have a bad signal or something. The framework doesn't change my battery life at all

I dont know really its kinda weird because when i uninstall it,it goes back to normal and as soon as i enable it the intense battery drain starts again

How many times have you tried it? I would download GSam or BBS. These are battery stat apps that can help detect where the drain is coming from.
ive tried it a few times now with same result
Gsam and screen shots. Will be much easier to help you.
What Xposed modules do you use?
I can't see how framework would drain battery on it's own.

I had the same issue, all i wanted was customizable quick panel, battery icon and reboot menu. So I found Cataclysm Rom and have been using that ever since with no issues
