After weeks of trial and error I have a solution to the battery drain.
**Turn-off ALL notifications. This is the biggest battery drain of them all!!!! Yes, all of them, not just calendar notification. The main bug has something to do with processor use for notifications.
*Turn-off time zone under locations settings. Actually turn-off iAds, and apple diagnostics as well.
*Turn-off any exchnage push email. This does seems to use more battery then on previous iPhones...not sure why. I still use 1 for work ( I had 2)...battery use is normal.
If you turn-off all off these, you will see a return to normal usage.... untill official Apple fix (coming soon!!)
I have tried everything written on the subject....only turning off notifications had the largest reduction that continued to work.
Every night since I purchased my 4s, my battery drained 20-30% in 6-8 hours...just with stand-by alone. I was lucky to finish a work day. I usually had to charge my phone at work.
2 days ago I used the above written fix (and network reset) and last night went to bed at 10pm, left phone off the charger for testing, unplugged at 5am....Battery dropped 2%. Now thats what it should be...
I made it for an enire work day...I only used 15%, with some emails, calls, internet, and bluetooth. (light to medium use)
Please try it and report back...
No more watching my battery drop every couple of minutes...
