The iPhone 15 series introduced a new battery health setting that allows users to limit the maximum charge to 80%. This setting is designed to extend battery health, but does it really make a difference?
MacRumors’ Juli Clover conducted an experiment where she limited the charging capacity of her iPhone 15 Pro Max to 80% for an entire year. The results showed that the battery health dropped to 94% after 299 cycles. While this is not spectacular, it’s not bad either.
Comparison to Other iPhones
Clover compared her results to two other MacRumors staff members who used the same phone without limiting the charging capacity. The results showed that the battery health of the other iPhones was lower, but not by much.
The experiment suggests that limiting the charging capacity to 80% may not make a significant difference in battery health. However, it may still be useful for users who plan to keep their iPhone for several years. By limiting the charging capacity, users can reduce battery degradation and make the most of their iPhone.
Practical Implications
If you plan to use your iPhone for three or four years, limiting the maximum charge capacity might be a good idea. This can help you reduce battery degradation and make the most of your iPhone without having to replace the battery.
In conclusion, while limiting iPhone charging to 80% may not be a game-changer, it can still be a useful feature for users who want to extend the life of their iPhone.
