Batery life Iphone

In general, you should expect 2-3 years of use before you need to replace the battery when it is down to 80% Maximum Capacity.

Your battery has declined only 3% in 6 months, so it would be reasonable to expect that it might be 94% at about 12 months, 91% at 18 months and 88% at 24 months. At your current rate, you should be able to go about 3 years from the purchase date before you need to replace the battery.

Your battery is doing very well. Don't worry about it.

What is important to remember is that the battery declines an average of about 1% over longer periods. It does not usually drop 1% every month.

The battery might go 3-4 months and not decline at all, then drop 2-3% the next month.

At 6 months, you have had enough time to get a general idea on how your battery is performing and what you might expect in the future. You will have an even better idea at 12 months.
