iOS 6.1.3 battery drainage

I have found out one of the main problems is that after the update it keeps trying to download emails 27/7 even if you dont have a email account on your phone i have found a way to stop set your fetch to manual for your email account then hard reset your phone holding the home & lock screen buttons till your phone powers off & back on this not a fix but defo improves battery life

I have tried turning off push noifications, turning off more noifications that I don't use, have no icloud nor email accounts, resetting celluar data/3G, turning off location services, and restoring phone to factory settings. None of these solved my problems. I have an iPhone 4 with the the latest iOS of 6.1.3. Any help on this? Can this be a hardware problem? You guys think getting a battery replacement will change anything? 😠

After doing all this @Demova you still have the problem?

Well I restored it yesterday. The battery use to decrease when it's on lock but it didn't yesterday night. 1 Hour, 6 minutes of usage, 9 hours, 44 minutes of standby = 79%. Is this normal?

I have iphone 5 32 gb & updated6.1.3 at yesterday i noticed that battery life improved my phone battery running 1.5 times than ios 6.0.1 like to be 18 hours

i used all day internet more than 85 calls , facebook whatapp browsing etc also avg 3 hours music & 30 hours video watch

Why other complaint about ios 6.1.3 i dont know. If software is universal ios 6.1.3 so i think promblem of hardware or carrior promblem only.

God some people are just blind to the facts how can it be a network issue when 6.1.3 is causeing the same issues whith battery drian on ipod touch as well witch dont have a network how do you explain that if ist not the ios like your saying

have you tried backing up your phone creating a new user profile on windows & redownloading itunes sometimes the IPSW file that you download from Apple via itunes by wifi doesnt correctly update to your device. If you have done update via the cable your best to speak to them on 08000480408. The problem with issues like this is their isnt a similarity to each persons problem with Battery drain & wifi issues as we all have different apps & content on our phones. Always wondered wether the Diagnostic & usage does actually help to improve their products or if like other Manufacturers they just include this to make us the consumers believe their is going to be vast improvement all thanks to their reporting tool.

Backing up & restoreing your device is a waste of time if your haveing issues because any bugs will b backed up & restored as wel best to factoy reset & totally whipe your device but to save you the time resetting back to only stock apps it dont solve this issue its 6.1.3 plain & simple my phone was totally fine untill i updated via lead on itunes & my 4s is only 6 weeks old this is my 4th iphone & this not the 1st time iso has caused issues all 3 of my 3gs kept hard restting after 5 or 6 mins in to a call due to ios 4.0.1 & all 3 of them did this straight out of the box

Just posting my last 2 posts drained 10% via wifi witch uses less power than 3g lol its insane how people dont believe theres a issuse with 6.1.3 that fact is since 6.1.3 people iphones ipods ipads all getting battery drain some ipods getting under 2 hours use on a full charge some ipads that lasted 3 days on full charge now lasting 4 hours apple really need to fix this and fast

This will be the last apple device i will ever buy i have a samsung galaxy with has been updated dropped several times left on charge by mistake over night & yet still works perfectly after 2yrs of mostly abuse apple are just unreliable & there biggest problem is the idiots doing these shoddy half assed ios updates that keep repeatedly causing problems for there customers & all you ever get is the same old bs trouble shooting from tech support when thay no fine well ios is the issue bad customer relations that is basicly bare faced lying to the customers

Does anyone know for certain whether Apple have acknowledged this problem and are working on a fix?

@JohannBelet... I don't know much about connection either, but it makes no difference it is just in 6.1.3!

and we have to wait. Not that we need to do so patiently.

I know my new 4S will not ALLOW any closure of 4G that I can find. I can turn WiFi off but not 4G..

AS to above suggestion of restoring blank phone. and adding each APP and waiting an hour to see if batt drains

HOOEY... I have a live to live and things to do!

I awoke this AM to a 20% drain during the night when 3 tweets were favorited! GAH!!!

I just keep turning off all recently used apps (because Apple is too stupid to do so when you close and go to home screen... and clearing free memory with SYS ACTIVITY Manager. I noted last nigh when Battery report came on when I plugged in that MAX phone usage for 'internet' activity is something like 4 hours...

Unacceptable!

ANYWAY I just keep sending out TWEETS telling people to NOT NOT NOT Buy a MOBILE APPLE PRODUCT till this is solved. That got a lot of action last week! Apple doesn't like that!

'REMEMBER ALL Do NOT Buy an @Apple MOBILE product until you hear they have solved 6.1.3 BATTERY DRAIN problem See tinyurl.com/cluk73z

This is link to this discussion!~

die erste version auf iphone 5 war die beste , keine akku probleme , das handy war somit unschlagbar !!!!!!!!! seit den scheiß neuen updates geht akku sehr schnell leer und verärgert mich sehr😠😠➖

Yes, Apple has knowledge of the iOS 6 problems. The iOS 7 upgrade will be nice, that is what happens with a updates they change your battery life.
