Battery capacity question phone

It is impossible to maintain Battery Health at 100%. Batteries are consumables and Battery Health will decrease as the phone ages. However, you can do things that will help get the most out of your battery.

Thanks to ASC User Lawrence Finch for this review.

Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles” ( some will be a little more, others a little less). As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.

The absolute best way to improve the life of your battery long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the night the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

Repeating again, but the simple answers.......

1) Make sure that Optimized Battery Charging is enabled on your phone......(it should be by default, but you can check by tapping on Settings > Battery > Battery Health

2) Plug your phone into the charger and let it charge overnight, every night

That's it.

Don't let it get really hot (e.g. don't leave in a closed car in the sun in the summer) and don't drain it to 0% and leave it that way for an extended time. Other than that, it's pretty hard to "ruin" a battery.

Oh, and don't smash it with a hammer. ;-)
