iOS 6.1.3 battery drainage

Sorry to be the bringer of bad news but I tried that a week back and no results 😟

I'm thinking it's something else constantly trying to get 3g/internet access and that's causing our phones to be constantly "on" and draining battery. I've spent the last couple weeks trying to figure it out but no luck yet.

Sorry to disillusion I use no other mail acct and they have never been PUSH!

Today draining about 15-20% / hour w NO USE OF ANY PROGRAM!

PS Why is everyone talking a out 3G using 4G phones? Also although you can turn 3G off they took that feature off 4g phones! As noted even Airplane doesn't turn 4g seek off!

Maybe that is part of problemif so we need to be able to turn it off!

Not all networks support 4G and thus the iPhone displays no 4G settings. Only 3G.

THANKS Jajaba I had never dug that far !

EVERYONE CHECK in Settings >Mail >Fetch New Data >Go down to ADVANCED they snuck in another iCloud PUSH HERE! Turn it off .. Or set to Manual , whicheans it will check for mail when you turn program on.

NOTE This is NOT the PUSH settings at top .. But a totally hidden one!

Sorry but so what? MY iPhone 4S has no way to turn 4G or 3G off ! That feature is gone!

I installed iOS 6.1.3. yesterday, and now I am experiencing batterry drainage. I had to charge my iphone 4s twice in 12 hours. Previosuly the battery lasted 24 hours. What a shame for Apple.

I solved my battery drainage. I bought a Mophie Juice Pack Air case for my iPhone5. If the phone dies, I flip a switch and I have 8 more hours or so.

That's not solving it. The problem still exists. It just isn't an annoyance to you anymore.

I had the same problem when i upgraded to 6.1.3. Battery lasted less than 5 hours after full recharge even when phone is on standby. The problem has to do with the mailboxes. I have disabled all mail accounts and the drain has slowed down considerably to about 1% per hour in standby mode. Try that, it is a temp solution before Apple comes with an upgrade that solves the problem.

As always, there are multiple issues that effect battery. So one fix won't solve every bodies problems.

Earlier I turned push off from mail, contacts and calendars and also on the advanced section.

At that point my battery was at 52% and I had 2 hours 15 mins useage.

Now my battery is at 40% and I have 4 hours 9 minutes usage.

It's too early to tell, but so far my battery life appears better. 48% got me just over 2 hours and now 12% has got me just over 2 hours.

Since 6.1.3 my battery has been dead within 4-5 hours usage. Now it looks as though its going to last a fair bit longer.

Ill update the thread tomorrow.

That's a pretty dang good battery life. I'm at 1 hour 34 mins and 59% and all I've done is some light surfing.

I'll try the turning all mail accounts off thing and get back at you.

You should download sys activity manager and tell me if your phone gets really hot. According to the app my phone is always in the "red" section which might be overrheating the battery.

Should last for 9 - 10 Hours with light wifi only surfing w/ brightness at 50 - 70% or 7 - 8 Hrs using cell data for surfing....

I am now getting 90 minutes usage per 20% battery. Which is a **** site better.

It seems my issue was related to the push settings in 6.1.3.

Fwiw I don't have any mail accounts as I use the Gmail app. I've turned push off on the mail, contacts and calendar settings. And in advanced I turned it off for my iCloud account.

Just checked some screenshots of my usage, that I'd taken when I moved back to my iPhone 5.

5 hours 32 usage.

14 hours 29 standby.

48% battery left!! Incredible battery life.

Then since 6.1.3 I've been getting 4-5 hours max usage. Which is terrible. Considering usage time isn't actually accurate and the time goes up even when it's in standby.
