I have an XR and as I am indoors a lot of the time, my phone does spend a few hours charing at 100% (although I unplug at night). It's rare that I let the phone run past 80% and even rare that it goes past 60%.
Is this likely to damage the battery?
This Macworld article says
isn't optimal, although it won't necessarily damage your battery. However, I've seen other people stating that charging to 100% is very damaging which is why Ios 13 will have measures to prevent it. Further still, I've seen articles state that ios12 already is designed to cope with charging at 100%, and the ios 13 improvements are more to do with overnight charging.
What's the correct answer? Also, as should I shut down the phone at night if it is not charging. Thanks for any advice.
