I was at 100% for almost one year. As soon as I did the iOS 16 update it’s been going down 1 percent a week. Very odd. Is this normal? Nothing else changed on my end.

Yea my iPhone 13 Pro battery has been degrading quick too. Glad I’m not the only one. 100% to 93% since beginning of July 2022 to now.

Not here. I have a 13 pro max since launch and I’m sitting at 98%. It was at 100% at the 1 year mark and fell to 98% in a month. I’ve been on iOS 16 since launch as well.

Even before Apple started reporting the battery health in iOS, I used the coconut battery tool to get a baseline of all the new devices we acquired. I noticed that some iPhones or iPads would get shipped with batteries that start with significantly higher capacities than official, pushing the battery health above 100% - in many cases, as high as 102 or 103%.

Because of the higher-than-anticipated mAh capacities in some of those devices, it would take close to a year of regular usage for Apple battery health to register a single drop. This higher-than-anticipated battery capacity is why many people would see %100 during the first 9-12 months of ownership. Once the battery hit the 'near' 100%, the drops would start reporting in the Apple battery health, and that is why many of us see a steady %100 for a good part of the year and then suddenly drops in %. These drops had been occurring since day one. Still, because the battery was dropping, say, from 104 to 103, to 102, and to 101, Apple kept reporting this as 100% battery healthy, creating this illusion of exceptional battery health.

Yeah I was at 100% pre-update (was using since beta) and have been seeing a decline over the past few months. Now I see I'm down to 92%
