Q: iPhone 5 battery life is way worse than iPhone 4

Mark are you on 6.1 beta 5

No. Still on 6.0.1.

I am restoring to the latest now. Once I charge fully overnight and use for the entire day tomorrow I will then report back with my findings. Here's hoping they fixed it!

Here my experience.

After lot of weeks with my battery discharging in a couple of hours, after a long chat with Apple support, after bad toughts like "throw against the wall", I did this steps:

. remove the cover with aluminium backside my son gave me

. set up the phone as new

. synchronize (instead of restore previous backed up from my iPhone 4)

. be amazed (from 6.00am 100% to 11.30pm 35% surfing, mailing, facebooking, twitting, calling with wirless and 3G allways on).

I swear I do not understand but i guess that the cover with aluminium backside win!

7 hours 15 mins all cellular no wifi... BEATS THE 4 HOURS I WAS GETTING BEFORE! I believe the problem has really been worked out! Very happy with that!

Oh and 18 hours 4 mins Standby!

AlwaysLookin4Answers-

Did you get a new phone, or just update to 6.1beta 5?

I am on beta 5 and don't see any changes. Battery is draining on 4G (3bars) even in standby.

Also, my wifi won't stay connected anymore.

I have about given up on this POS

Hey cocktail, I did get a new phone. I returned it literally more times than I should admit lol but I wanted what I paid for.

Anyway this is a brand new phone built in December. I did a fresh install of the new software, battery much better- except I'm completely with you on the wifi situation! *** is that? It connects but it is so weak! Even in front of the router the bars drop! Very weird... I'll take better battery over wifi any day tho (as if I should have to) annoying.

iOS 6.1 is here. I will let you guys know if there is any change as far as battery life is concerned.

Since upgrading "Personal Hotspot" is now greyed out. What gives?

Working fine here. Perhaps a hard reboot (home>sleep button combo) Or if that doesnt help a settings>reset>reset network settings.  If still not working settings>reset>reset all settings (which wont dump your data or apps). Lastly if none of those steps work, restore from iTunes.

BTW did you do OTA update or iTunes full update? I have performed OTA and so far no issues to speak of but lots of folks with issues have to do iTunes full restore to resolve quirky stuff like that.

I am a 4s user not iPhone 5 so want to be clear there.

Please, i know it's very soon yet but it would be great if you're go reporting your experiencies about the new IOS 6.1 and battery drain during the next days to know if you notice some improvement about it.

maybe you should get the phone replaced. Because even on 6.0.1 where wifi was a huge issue i was still getting full bars and it would drop as i go away from it. Which indicates it is working as expected. I am on 6.1 official build and my wifi has always been the same. I had beta 5 yesterday before i restored to the official build and the battery lasted me about almost a full day with almost 7hrs of usage on lte. I guess every iphone 5 works differently compared to others..

If restarting doesn't fix it, try updaring your carrier profile.

Not seeing any major difference. Held charge at 100% for about 30 minutes. Now the usage is 1 Hour 43 minutes and the battery reads 77%. No heavy usage. Just one message over whatsapp. 7-8 web pages optimized for mobile phones. 3-4 emails - reading and not writing. That's pretty much it. Push email was on. Now have switched that off. Pretty disappointed.

Note: I am on 3G. And that is what I am disappointed with.

I see as expected stats on Wi-Fi. 2G is okay ( around 6.30- 7.00 hours of usage)
