Battery Capacity
Battery capacity of iPhone 11 Pro Max has been dropped to 97% within three months from the day I bought it. What should I do? Is it normal?
iPhone 11 Pro Max, iOS 13
If you charge it once every 1-2 days, you’ll end up with 15-30 charge cycles a month or 45-90 cycles in 3 months, which is roughly 10-20% of the 500 charge cycles it takes for your battery capacity to fall 20% to 80%. So you’d have lost about 2-4% battery capacity (10% to 20% of the 20% battery capacity you’d have lost at 500 cycles), which is to say 97% capacity at this point is normal.
