I read some say battery is great and some not so great. I'm getting ok battery, not the best. 6hrs of usage and 15hrs stand by that's with LTE 9-6 at work and 6:30-10 wifi at home. some browsing, email, iMessages, Facebook, flipboard & instagram. I see some getting 8-10. Maybe we can all together figure out if any apps we are using or just have install are draining our iPhones. Please Share.
