My iPhone 6 battery meter is stuck at 100%, this following latest software update to iOS 12.4.9. The pone functions normal but would suddenly and unexpectedly shutdown, presumably due to battery drainage, yet still show battery at 100% before this. After charging phone and startup, the phone battery shows 2% and it charges to 100%, then it gets stuck again at 100%. I tried phone reset, but it did not fix the problem. Any suggestions?
iPhone 6, iOS 12

What worked so far is not charging the battery to 100% (in this case only to 70%), and it’s working so far. The battery meter displays energy drain. Thanks again for all the help.
Thanks for the assistance. The battery capacity shows at 91%.
Still no resolution to battery meter stuck at 100%.
Since the problem began with the last iOS upgrade, maybe it’s a glitch?
It didn’t work. Thanks for trying. The problem is ongoing.
