My iPhone 6 is doing pretty much the same thing, though when it turns off doesn't seem to tied to any particular percentage. A few days ago I made a call and pulled the charging cord out to chat. I walked outside, and 20 minutes later the phone was dead, from 100% when I walked out. I put it back on the charger and checked about 5 minutes later and it said it was at around 65%.
- 2dvisio 9y agoIf you haven't seen an Apple genius you should probably. I got mine replaced now as my iPhone 7 continued to show signs of erratic battery behaviour after any SW attempt at fixing it. Apple customer service has been quite useful, however it has taken me lots of time and effort while I was effectively trying to 'debug' the issue for them. In addition, the tools that Apple has to check the battery is very vague. When my phone was tested it had a Green/Red/Yellow chart with no axis whatsoever with a dot showing the status of my battery (Green borderline with Yellow). We have tried the phone of my GF, a 2 yrs old iPhone 5S which has completely random battery behaviour. In this case the graph showed only the Yellow square but with no indication of where the battery was in terms of battery life. Now considering what to do with the iPhone as I am now a bit disappointed by how this (very) high end phone behaved.
