My phone is not going to 100 percent it is stopped at 80 percent everyday what can I do

Hi aurangzeb144,

Thank you for participating in the Apple Support Communities. If you have Optimized Battery Charging enabled, this might be the reason. Here's a link to help: About Optimized Battery Charging on your iPhone - Apple Support

You can also check the battery health to see if that may be the issue. A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge. Here's more information about that: iPhone Battery and Performance - Apple Support

Have a great day.
