Battery health dropped after update
Hey everyone! I recently bought a second hand iphone 15 pro max just last September 30. It had 96% health and no serviced parts so everything is original.
I updated to ios 27.0.1 around October 1 or 2 and it had the same battery health after the update. I checked my battery health last week and it was still 96% and just today I noticed it went down to 85%. I only charge my phone when it’s 20% or lower so only when needed. (I use a 20W power block and cable from ANKER)
The battery health jumped and was a bit alarming for me so I asked the seller and they said it usually happens after updating the ios so I’m posting to see if this happened to you guys as well.
