There’s a setting that won’t let you phone charge past 80% so help expand the life of your battery. If you go to settings>battery>battery health all you have to do is turn off optimize battery charging! It basically recognizes when you normally charge your phone and if it’s not around that time it only charges to 80

As far as I know, the battery calibration thing is a myth especially with the batteries currently made today. If I'm wrong I would like to see some articles/ tests that prove otherwise.

As for the battery, I would recommend going to Apple and get the unit exchanged. Not to jinx you or anything, but make sure you keep that phone super secured. Apple might fight back if there are any dents/cosmetic damages on the unit.

Good Luck.

Change the location of your charger, it happened because of the charger brick being warm. Mine was stuck at 80 and now it’s working

This is usually caused by the battery getting too warm. The official answer from Apple is "Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location."

Hope this helps!

If it's under warranty the best thing to do is to take it back for a new one.

But you can try running the phone down to zero (or as close as you can get) and try a full charge. Sometimes the battery monitoring chip needs to go all the way down so it can calibrate.

I just did the ios 13.5.1 update about two weeks ago. Once that is done, my phone's battery drains rapidly. Battery life also seems to be decreasing. What is the reason for this? Is there a solution?
