Danggg. My iphone 8 only 6-7 months. But max capacity only 94%.

Well i always used my phone as hotspot and charged the phone as i like, means i didnt wait the battery to drop till 40-30 then only i charge. Even if its 85% and im using waze, i will plug in the car charger. Hahaha

That's about two years plus right? Planning to change it while the replacement program is running this year?

Ya, good deal. Better go earlier since almost half the people I spoken to is waiting for November/December to change their batteries.

The other half will just change their phones

before update to iOS 12, it showed 89% health

after update to iOS 12, it shows 90%.
