About the batteries health of 14promax

Why does the battery degree of 14pro max drop so fast? In the past, there were 95% of devices in less than a year, but mine is only 88% now.

How many months have your owned your iPhone? If you've owned it since launch day, battery health decline of 1 - 2% per month is normal. It's been a year since the 14 Pro Max was released, so a decline of up to 12% wouldn't be unusual. You have to remember that no two batteries are exactly the same, nor will they be used in the exactly the same way. Every time you charge your battery, its health will decline. this is what batteries do. ALL BATTERIES.


When your battery health dips to 80% or less, it will then be time to pay Apple to replace the battery in your iPhone.


Things you should be doing to preserve the health of your battery:


  1. Turn on Optimized Battery Charging in Settings > Battery and charge your iPhone at night while you sleep, EVERY NIGHT.
  2. Avoid letting your battery decline to 20% or less and NEVER let it fully deplete, which can speed up the reduction in battery health.
  3. Read this link --> Batteries - Maximizing Performance - Apple
  4. Stop worrying about Battery Health decline, which is normal and cannot be stopped
