Did you update to iOS 6.0.2 to fix supposed "wifi issues" only to find your battery life has gone to crap?
Me too!!! Not only is the iPhone 5 NOT jailbroken yet, the 6.0.2 battery sucks worse than the Mayan's could have predicted.
For those of you that follow my blog, my iPhone 5 and I didn't start out on the right foot, with a bad wifi chipset right out of the box. Thanks to AppleCare+, I had a fresh unit in 24hrs time....Again, that's what I get for going against my code: Wait for bugs and a Jailbreak before upgrading....Yeah, I miss my JB tweaks big time and there are days I wish I would have just stuck with my iPhone 4......but it was time for change and made good fodder for my blog....
Back to the battery issue.......
I experienced major drain after the update to 6.0.2. I searched and searched for a solution to no avail. After going tens of Google search pages deep, I found this article......, CLICK HERE.
So I tried it and it appears to have improved my battery life. I use my bluetooth headset or my JamBox while streaming audio my entire workday, literally. I usually have to plug the 5 back in after lunch. If anything, after trying this potential fix, my standby time now makes it through the night and the battery seems to perform as well as it did originally, having added an hour to my usage. Remember, that's constant audio streaming over wifi and LTE using bluetooth.
Here's what you do:
1. Kill all background apps using the app switcher. Double tap the home button and tap the 'x' on the app icons as they appear at the bottom of the screen.
2. Go to the Settings App, --> General, --> Reset-->Reset All Settings. This will not delete your data, it resets all network and iOS settings. You will end up signing back into things and turning locations services back on, etc..... Sort of a pain, but I feel it was worth the try.
3. The iPhone reboots. For good measure, I completely turned off the phone by holding the sleep button and powering down. I turned it back on and let it charge completely.
I can verify now, that my iPhone 5 on iOS 6.0.2 charges faster and the standby time is back up to par, only losing a small percentage through the night.
Here are my screen shots. These were taken at exactly 14% battery remaining. The conditions for both screen shots were the same, bluetooth headset connected, streaming iHeart and TuneIn Radio.
Again, not sure how or why this worked, but in my opinion, it DID. My standby time is great and I picked up and extra hour of streaming with my bluetooth headset. These screenshots do not reflect normal standby, as I was purposely streaming and using my bluetooth to drain the battery to 14% to test this fix.
If your battery life sucks, give it a try, if you don't mind having to enter your network passwords and the such. Credit goes to the original poster in the Apple forums.
That's how Bruce T fixes iOS 6.0.2 battery drain.
