iOS 6.1.3 battery drainage

same here. Never had this problem before - it appeared with 6.1.3 update. : -(

turning off all notifications and apps - it's definitelly not the way to solve the problem.You can save some % of your battery usage but ut will not help in general. The drain remains.

I wonder why there are no representatives of Apple? Why keep silent?
When will soon be corrected firmware 6.1.2 or turn sign for rollback.

Same issue here. Can't make it through a normal day anymore with one battery load.

Sorry *6.1.4 or 6.1.3a,b,c,d,e....corrected

Same problem with 3 iPhone 5 in our company. The only not updated iPhone has still better Battery usage ....

Impossible to get a working day managed without charging ... was so never before.

Same problem here....very annoying. am experiencing it both on a iphone 4 and 5 after installing 6.1.3. Have tried to kill apps, push mail and restart but nothing seems to help.

Apple where are you? Keeping silent is not a policy for such a brand. : (

Ive also had the same prob ever since updating tp 6.1.3 ive never before had any problems with updates i have a Iphone 4s its frusterating because i cant use the phone for my business anymore because the battery is just running out of power . It was perfectly fine till i updated!!!

I have the same 6.1.2/3 battery drain issue, and I have done everything, including a full factory reset, and still have the problem. The other night, I charged my iPhone fully before going to bed, killed all open apps -- and when I woke up my phone was at 22%. I have no push e-mail, no reminders set, etc.

My issues first started with the Exchange bug, but when I did the workaround (don't respond to meeting requests), my battery usage went back to normal. With 6.1.2 and 6.1.3 (the Exchange "fix"), my battery usage is now consistently bad.

It's possible that my battery just decided to go bad, the day that 6.1.2 came out -- just not the most likely explanation...

Make a backup of the phone. Restore the phone as New. Do not add any apps. Do not create any email accounts. Do not sync the phone. Charge to 100%. Watch the battery life. If it drops at a significant rate (more than 1% per hour) with nothing installed you most likely have a hardware problem. If this resolves the battery drain restore the phone from your backup, and test again. If the battery problem returns you have corrupt data in your backup.

i read that there is no way to downgrade to 6.1.2 can anyone confirm this? i downloaded 6.1.2 for my cdma iphon4, but itunes will not install it.

You can't downgrade to 6.1.2.

iphone 4s won't charge after updated to ios 6.1.3

Different adapters and usbs have been tried, and now power has been drained.

Apple support says there is nothing they can do about it, and they surggested me to pay 199 for a new iphone.

Is there anybody having the same problem?

Those 99% may not be posting. Just calling tech support. Some times I get a cool tech support agent, and the tech guy tells me all his phone calls are due to battery drain. Even my Apple store said the same thing about the update and iPhone not lasting as long as it use to. This isn't the only forum on battery drain, Some people go elsewhere because of all the rules of posting on here, I think some of the rules are a joke myself. I don't have it backwards! I've done my home work on this issue for months! Starting with 6.0.2. A lot of people I know have switched out phones for another one because of the battery. I don't want to get in a B------g match over who's right and who's wrong. This battery drain problem has been going on for months! I hope Apple has a fix soon.
