Iphone x battery max capacity

Hi just installed ios11.3

I checked the mac capacity of my battery,since the iphone x is only two months old i expected a 100/100.

Sounds pretty normal to me. There are a lot of little variables. One of them is that there might be a standard deviation for original capacity due to manufacturing variations.


Apple rates the battery at 500 complete charge-discharge cycles before a typical reduction in battery health to 80%. So if it's an average 250 cycles per year, a linear degradation would be expected to mean a reduction to 90% in one year. 99% doesn't sound like there's a problem.


Also - it's important to understand that the battery health number is just an estimate.

I have this issue as well. I have iOS 11.4.1. I did not even have my iPhone X for 2 months (about a month and a half) and today it is showing 99% max capacity.


I understand the comments about battery life span... But it just seems a bit soon IMO for the battery to show signs of decline after only 45 days. I would think maybe after 4-5 months it would be normal, but not less than 2.


On average I usually only need to charge once at night. I can go a full day without having to charge so I don't think I'm an extensive user.
