my experience contradicts the notion that random shutdowns are directly correlated to battery degradation.
just over a year ago, the then 3-year-old battery on my 6s was experiencing very occasional instant shutdowns, usually when the battery indicator was under 10%.
so i got a new (presumably undegraded) battery through the free replacement program, thinking it would improve things, but random shutdowns are worse and now my battery indicator goes to 1% for hours at a time.
- mark13 7y agoThis was my experience too with a 6s. Even with a brand new battery I'd get maybe 3 hours of use out of my phone (and I'm a pretty light user) and furthermore it would often shut down registering as much as 30% remaining. I bit the bullet and upgraded to a new iPhone 11 a few months ago, and I now regularly end the day with 70% battery life, with no change to my phone habits. So, at least anecdotally, there's more to the story here....
