iPhone XS New iPhone XS Battery

[rctneil]

Hey,

I purchased a brand new iPhone XS two weeks ago and two days ago I noticed that the Battery health has dropped to 99%.

Is this cause for concern? I know batteries are consumable items but surely it shouldn't be dropping in max capacity two weeks after purchase.

I’ve had batteries come from the factory 96-108%. Batteries are a chemistry that fluctuates. I use coconutBattery on Mac to watch and observe mine. I wouldn’t worry about it. Remember, battery wear isn’t linear like a glass of water. Some fluctuation is normal and fine.

I've just started to log mine in CoconutBattery. I'll see how it goes. Thanks
