iPhone 11 and iPhone 12 series downgrade performance after updates

Testimony, that my iPhone 11 when new could get almost get two days battery life. Now I’m lucky to get three hours. There’s been no changes in settings, and battery charging optimization has always been turned on. Looked for advice on how to preserve battery life and settings to use for this and follow them.

Under settings, Battery health when under AppleCare plus, which expired just a couple months ago, was in the high 90%, and now suddenly says 87%, which I believe anything under 90% not considered healthy. I have also been reading in various places that is there is an ongoing class action suit against Apple accusing them of purposely degrading performance, specifically battery life, and specifically affecting iPhone 11 and iPhone 12 series.

Any advice on how to extend battery life on 128 GB iPhone 11, or anything to do to circumvent the changes that have been done with updates to the operating system?

Best, Seth

Hello,

With any new version of iOS there are always maintenance and re-indexing tasks to be performed. It should settle down in a few days. These are the standard steps for short battery life

1) Have you tried a restart? If not, do it now.

2) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.

3) Check “Battery Health” in the link:

iPhone Battery and Performance

4) If all else fails, consider a battery replacement:

Good luck.

P.S. it is generally recommended to replace the battery when the battery health falls below 80%
