Hello all,


Have iPhone 5S from UK. IOS 7.0.3 installed. Experiencing the following problem.


I noticed that the battery drains too fast on the 2 days old phone.


When i go to sleep i put alarm on, close all apps, switch off the sound, put the device in airplane mode. When i wake up, 8h, the battery drains 10% or more. On the iPhone 4 this wasnt an issue, max 1-2 percent, but in most cases it remined same percent. Why is this battery draining that fast with nothing running? Any solution?


Also when phone reaches 1% it seems to sit more on it than it should before recharging, as if 1% is the same as 3% i can compare this because i see how fast percentages deplete before that.


I am having a hard time believing that this is the device? Or is it? Should i reset? Delete some apps?


Please help....

MacBook Pro, OS X Mountain Lion, Early 2011 MacBook Pro

    Basics from the manual are restart, reset, restore from backup, restore as new.

    So here is the sad story.


    I completely wiped my phone to ios 7.0.3 through itunes. Set it up as brand new device, turned of the paralx effects etc. The battery during the days seems to have improved, maybe because i have less apps, maybe because i truend off a lot of things...


    But during the night still the same 10% get lost. 8h - 10%... in Airplane mode... so 80h is max standby i can get out of it then? What about the promised 250h?


    Any other ideas are appreciated... it should in no way drain that fast, i know the device is new, maybe it needs a few cycles or something of charging discharging?

    I have similir problems . I bought iphone 5-s on 25 October . I restored my phone from icloud backup but i noticed that my phone battery is draining so quickly even less than or simi,ir to its predecessor iphone 5 . I restored my phone using itunes and set up it as new iphone but still its not giving me good battery time . I have location services turned off , background app refresh turned off , push notifications turned off , mails using fetch manual . But when i see the usage statistics it shows me 2 hours 31 minutes usage 7 hours 38 minutes standby time 34% usage . Honestly i did 3 to 4 phone calls very short calls , whats app messages BBM messages using BBM app and 5 to 10 min videos on youtube . This seems poor results as what apple says .

    Hi all,

    I think I also have similar problems. Dropped 5% of battery within 10 mins( only turn on wifi, and used 2 apps). In the same situation, my old iphone4 was much better than i5s. Or it's just normal??!

    I have the same problem!!! I have a UK 32gb gold model.

    My phone is EXTREMLY hot all the time, and my battery last for 3-4 hours on standby!

    I found out or at least I have a theory.


    I went and wiped my iPhone. Put it into airplane mode, setup the alarm, but only difference with the drainign battery situation is no installed third-party apps.


    So 4.5 hours later i had only 1% battery drain. My collegue at work also has an iPhone 5S, and he doesnt have many applications, his batter drains 1-3 percent per neght.


    So guys with most certainty I can say it's some applciation that is malfunctioning, we need to dig deeper to see what app can be causing this. Also it may be some motion chip related application, or Facebook or something, which can try to keep connecting to the internet.

    same issue, bought my 5s in Oct. it drains my battery at night even when I am not using it.


    went to apple store twice. They said the diagnostic of my battery looks fine, so they won't be able to replace my 5s. They suggested a few things including restore as a new phone, close bluetooth, wifi,... but none of them works.  Now I am stuck with the phone with max 2 hr usage. Please help!

    I have the same problem too. I sent my iPhone 5s in for repair and they said that they replaced the battery, but I'm still having the same issue. I've tried everything, from a restore, to turning off location settings, Siri, iCloud, wherever. Nothing seems to solve it. I've been a long time Apple fan, but This draws the line. I'm selling this piece of shot phone and getting a Nexus 5 or the Galaxy S5 when it releases. **** you Apple. I will never recommend your products again.
