Hi, i have a iphone 11 pro, i have updated to 14.4.2, my battery health is 78, my battery percentage drops fast, when it reaches 1%, it works several hours with that 1%, if i restart the phone the percentage goes up and again drops and when reaches to 1%, works several hours. Do you have any idea what i should do to calibrate the battery??

If your battery health is 78%, you need to get it replaced. When you do get a new battery, do not let it get below 20% charge. Draining a battery is bad for it.
If your battery health shows 78% then it is time to arrange for a replacement.
