Ios 18.3.2 battery Drain on iPhone 16 pro

i just got my 16 pro it has 6 cycles in it and last week I charged it to 85% every day and I put it down with 38-40% at night. 2-3 days ago I updated to iOS 18.3.2 and ever since then my battery has been draining like crazy doing the same things on my phone that I did last week my battery drains like 2 times faster than it did before. How is this happen on a new flagship phone ?

iPhone 16 Pro, iOS 18

Same here, absolutely same. 6 cycle used to charge 85% but after update battery is draining crazy. My question is it’s better to charge 100% using optimized battery charging or 80-85% for long battery life?


Charge to 100% using Optimized Charging. The iPhone’s fancy electronics don’t allow the battery to charge to 100% of its maximum capacity by default, so just charge to 100%.
