thanks but I didn't have iPhones ,.. all my prior phones where HTC dating back to the HTC pro, then pro2 then EVO then EVO 3D ... finally succumbed to the iPhone after using the iPad 2 ... all of my three iPhone 5 where activated as new phones from scratch thru iTunes usb hookup then email accounts entered.
I did read up on other less drastic solutions and a couple have helped
1. if you don't have a strong reliable LTE signal your better off disabling it
2. disconnect all programs running in the background that you are not currently using or shortly plan to use
3. check all programs thar need location services and deny access if not currently in use and needed... don't advise turning it off altogether because you lose find phone capability
4. turn of Bluetooth and wifi if not in use.
THEN let your new battery completely drain and recharge to 100% overnight ... repeat one more time and then compare battery life .... today I have 2hrs use, 20 min call time, 11 hrs standby and the phone still has 60% left...yesterday it was down to 20%
I still note that while standby life greatly improved, it does use a lot of battery time when using apps, especially mail, safari, Facebook or data use ...
keeping a log .... trying this out with all three phones and will report back in a couple of days ... maybe I will wind up changing the phones if the battery issue is not resolved ... the same thing happened with my EVOs 3D and the solution was new batteries. ... apple may have a huge batch of subpar batteries out there same thing happened to HTC ... lets see how this plays out ... I have the 64G models and at $900 a pop we are entitled to a top tier battery, specially if you need a technician to install the new battery!!!
