saw the website and try on my ip5 6.1.3 & it works for me. Phone able to standby for more then 14H. Yesterday was jamming on the road, so just use the LTE for 3 hours and from 100% to 60% watching apple movie trailers, VEVO, youtube and facebook. Used up about 400MB. Some of the instruction didnt really set. But the reseting of the network and resting the phone setting works.
Not yet try on 6.1.4 If those tried, can give some feedback.
Solution for battery issues without "set up as new iPhone" - MacRumors Forums
Objective: hit at least 9 and a half hours of usage. Without setting up as new iPhone
***SOLUTION***
1. DFU restore your iPhone 5 to 6.0.1. You HAVE to do a DFU restore. This is especially so if you updated through the wireless updater in ios. (Don't be lazy)
2. Restore from your favourite back up
3. In Settings>General>Reset, Erase Network Settings. Phone will reboot.
4. In Settings>General>Reset, Erase All Settings. Phone will reboot.
5. Set email notifications to every Hour
6. Turn off auto brightness and set to 25% to 35%. *I doubt anything more will be comfortable, but its really up to you. Just try to keep it as low as possible*
7. In Settings>Privacy>Location Services>System Services, turn off "genius for apps" & "location based iAds"
8. In Settings>General>Date & Time, turn off "Set Automatically"
9. In iCloud, turn passbook off. *optional if you actually use passbook*
10. It is important that you maintain these settings in the first use immediately after these changes. After the first 100% to 0% use to see if the changes actually worked, you can just use your phone and find out which app/perferred setting actually drains battery.
