Hi, I've had the iPhone X since 5th March of last year and I was just wondering if it dropping to 90% battery capacity is ok or normal?
 
This completely depends on your usage. If you go through more charge cycles then it would show lower battery capacity. There’s no average.

It’s not possible unless it’s defective.

The X has good quality battery suppliers. If you start at 100% / 0 cycles, you’ll reach 90% no sooner than 250-350 (avg 300 cycles or more). It’s very unlikely you consume even one cycle a day, leave alone 2+ per day. And even if you did consume 2+ cycles per day it would take 5-8 months to reach 90% that too if you’re unlucky.

For reference my X has a battery with 190+ cycles and I’m at 99% after some 6+ months or so.

Read again. You said March 2018. Then it’s perfectly normal.

You’ve had some 15 months so I guess 350-450 cycles already. So 90% is normal.

Thanks! As long as I have a normal battery .
