Ok guys just try this....
All the information on this thread got me about 1% to 2% battery drain per hour..
1 Do a all ....." Reset all settings"
This will get the IR sensor off incase it is on all the time.... (I have found that the IR sensor triggers it self on with out any notice and keep being on .... Guess its a bug apple have to fix it)
2 Keep every thing off... Like location service & sending data back to apple ect ( but right now I have location service on for find my phone and Siri. Location service for system services are off. .... My usage is with this settings....
3 wifi and blue tooth off
4 My Siri is on however
5 Now the most important thing is keep cellular date off.... ( you may on it when you want to use Siri or I cloud. )
But my usage mentioned is without using Siri, iCloud or the Internet. I guess still my usage is ok
6 on any service for like wifi etc when you want to use it but off the service you used after you done..
7 close all back ground apps opened when ever you can... By double clicking the home button and then closing the opened apps..
8. Put your phone on stand by no sooner you finish using it by pressing the on off button so that it will save some battery juice..
9 do as many full battery cycles as possible as it improves the battery.... Not just the first 2 or 3 cycles...
I am no tech buff.... All the postings of our brothers and sisters of this apple thread helped me...
But this is the stuff I did to get the battery life that I am getting now...
Well this is not a solution ... Apple will have to give the solution. But at least to survive till then..
Oh.... One other thing... If you find suddenly your battery life is going down after a few cycles... Do a settings reset... As I would guess some phantom activity has triggered.
Good luck guys...
Hope this would help.... ( most have been mentioned by others... But this is the sequence that worked for me)
Good luck and keep me posted...
