Why does my phone battery run out so quick over night?

last night I charged my phone to 80 percent and unplugged it before I went to sleep and when I woke up the battery was at 17 percent so please help

1. Running apps- Turn them off
2. Turn on Power Saver ( If you don't mind the screen a bit darker)
3. If you just press the button to turn the screen off , Hold it and shut the device down. I think that will turn all applications off :P
4.Remove apps you don't use (And uninstall)

If you have an iPhone and just got the iOS 7 then that might be why. My mom did that and it started draining the battery really fast

there is something on your phone running ,try restarting it before you go to bed ,even restart it before you charge it because restarting also takes batteries ,this will turn off all running programs ,if you still have a problem you may need a new battery

That's what happened exactly to me today... Last night it was at around 70%, today that I woke up, it was around 17%...

My hypothesis is that it might be the backgrounding applications... That take up memory, and drain your battery... because it's saving all the recent messages and some sort...

My other hypothesis is: it might be because of the firmware... 7.0... since it's kinda new... it has to work on bug fixes and so on..

- If you have any questions or concerns, please reply or email me ( located my profile info ) Have a nice day!!

Most certainly because of background apps, iOS 7 also has Background App Refresh where it will periodically refresh backgrounded apps, turn it off in Settings -> General -> Background App Refresh. Also make sure the GPS icon is not being displayed as that would mean some app is still using the GPS draining battery.

Yeah.. The thing to understand that there's still glitches and crashed in the system so that's main reason behind apps using more battery than usual.. Which you unfortunately cannot downgrade back to iOS 6 >.<

I've been using iOS 7 for more than a few months now, and my battery has improved over iOS 6.

Yeah same here... The iOS 7 release drains my Battery faster... For my iPhone and iPod Touch... I've recently tried to find out the battery percentage on both devices... The beta was way better in battery and also had less crashing and glitching than the release or final... Which makes me think... The beta was better at holding the battery and other stuff as we'll... And the final build is still glitchy and Drains my battery... Without running any applications in the background... I also disabled content being used in the background... I left it without using and still drained.... I feel as if apple where to know and getting something... Not sure, security perhaps...

You actually cannot break it in wrong as it is a Li-Ion battery. They are myths and not true one bit.

double tap the home button, and press the minus on all of the background applications, because those are what take up the battery.
Hope I helped!

Go to your settings and make your screen lighter because my phone kept doing the same thing so I lightend the background and it helped.
I hope I helped you!

because you sleep more than you think you do so for instant you sleep for 10 hours but u think that u slept for 6-8 hours so that is why u think it runs out more but it doesn't

I have a phone and it did the same thing i charged it for the whole day and night without touching it then the next morning i went on it and i was on it for bout 2 mins then it said low battery then shut off on me. It could have been from someone unplugging it or your battery could be dying. Is it working now these days? also it could also maybe be having to do with having way to many apps on ur phone so you should delete the unwanted ones.

Its because you don't completely turn off the phone. When you press the off button, it goes into sleep mode. In sleep mode te battery still runs so just hold the off button to completely turn it off.

You should turn off your phone after you unplug it. Even though your screen may appear off, your phone`s not off. Just turn it back on in the morning

if you have iOS7, go to settings>general>background app refresh>switch it off.
I did this and my battery stayed a lot longer. If you don't, or just want more turn it on airplane mode. also, delete the apps running in the background by double tapping the home button.

Its better to disable all data connections over mobile networks to save power while not using the internet. Turn off GPS, Bluetooth and Wi-Fi when you don't need these features. You can turn them off.

I used to have the same problem with my Android phone(s). Android phones are great phones it's just that the battery would not last too long. Like my HTC Evo 4g last for about 8 hours** maybe, just depends on usage. Android phones use battery for backlight, phone calls, apps that run when you don't use it etc. The best advice for you to do to eliminate battery usage on your phone is to download an Battery App Saver off the Android Market (App Store) on your phone. The best app that I recommend is: Easy Battery Saver. It kills all the apps that you don't use and saves your backlight making your battery life longer. So I went from 7-8 hour battery life to over 12 hours of battery life and for an Android phone that is pretty good! The only thing that gets Android phones compared to iPhones is the battery life on iPhone are alot better but, Android phones are getting better with that.

Your phone is probably running apps in the background. If you have an iPhone with the new iOS 7 installed on it, they are having problems with the battery longevity. Just plug your phone in to charge or shut it down overnight.

The screen and GPS chip draw a lot of power. Some phones let you turn off the GPS chip to save power. It should be easy to shutoff the screen. If this doesn't work you may have a defective battery.

your phone could need a new battery. my ipod was running out quickly recently, every 5 minutes it would be at 20 %. but when i replaced it (because it was cracked :P), the battery saves slower. so you might need a new battery.

Always make sure you turn it off. Sometimes turn your brightness down. Close all running apps. Also turn your phone all the way off and on again!

Do you play it while it's on the charge? Sometimes when people charge it too much it damages the battery and only lasts for short periods. Try turning it OFF completely and uninstalling applications that are going unused

IF you are on facebook. logout of the because ever update from facebook will make the battery deplete when you are done. Delete must of the apps you don't use. Charge the phone like every time it is about 45% or lower. Have the power saving feature turned on. Have the monitor off if not in use. Don't don't anything on the phone when it is charging. If none of this works, then see if you can buy another battery for the phone.

Hey KonradBienias,

This has happened to me alot; infact a few months ago
I replaced the battery because it was going bad to the point it was
swelling. Your battery maybe getting heavier as well. Even if there are
no clues on or around the battery that is usually a sign that it is going bad. Even though cpu intensive apps may run in the background the battery would not go from 80% to 17% just sitting idol with running apps and none or very little messages and calls in an 8 to 12 hour period. I hope I helped let me know, reply back.

if you can replace the battery, if not you should go to a store, and also if you have apps running stop them. Also keep your phone plugged in over night this won't damage the battery if it isn't already damaged
