If you happen to be one of of the people who get a bad battery, which is extremely rare despite the number of threads about batteries on this site, just take it back to who ever your carrier is, I believe Verizon is 14 days...AT&T will probably match Verizon just to stay competitive.There are no concerns about battery life. If you want the phone, get it. Don't let the naysayers ruin it for you.
Your phone should be in pretty decent shape functionally. If yes, then the prudent choice would be to stick with it until the iPhone 7 comes out or even longer if you can. If you are facing some critical functional issues with your phone, work with AC+ or even your warranty to get the phone replaced at zero to minimal cost.i currently have the iPhone 6 plus. Was debating whether to buy the 6s plus or not, was going to until i heard the concerns about battery life.
Can some give me a little direction here.
