My iPhone 6Plus acted strange so I did some searching and it appeared the battery was the culprit? I called several places and they wanted $75 to $150 and two or three weeks and I found the repair kit IFixIt which happened to be in stock at our local Fry's here in San Diego. I bought a kit for my wife's older 5+ to test my ability and low in behold IT WORKED! I needed my magnifying visor from good old Harbor Freight and plenty of light on the phone and patience. Those kits had all the mini tools needed and their website had great images showing how to do it.

That was a year ago and so far so good. I'd suggest trying that before spending lots of money on another phone?
