With Optimized Battery Charging enabled, you
might sometimes see your battery stop charging at 80
percent, but don’t panic. Don’t wait too long trying to
make it charge higher, just use your phone as normal.
If Apple’s intelligence about your battery use habits is
correct, you shouldn’t run out of charge. If you do, be
sure to use the Feedback app to let Apple know that its
beta software isn’t behaving as you expect.Other tips for improving battery longevity
Your battery wears out from more than just charging
and discharging or holding on to maximum charge. Your
iPhone has sophisticated charging circuitry to help
keep the battery in good health, so you shouldn’t be
expected to do much to keep that battery working well.
Still, here are some other tips that may help keep your
iPhone’s battery working its best for as long as possible.- Avoid excessive heat. Charging up your phone in
very hot car is a bad idea, for example. - Rapid changes from very cold to very hot are bad for
your battery, too. - Try not to let your battery completely discharge.
Keeping it above 20 percent or so, if possible, may
help it last longer. - If you’re going to leave your phone unused for a
week or more, run down the battery until it’s below
80 percent and above 30 percent, then power it
down completely. - Know your usage habits, and don’t fully charge your
iPhone when you don’t need to, even if the Optimized
Battery Charging feature might charge it further.
