The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.



Protect & Prolong the Life of your iPhone's Battery:

  1. About the battery usage on your iPhone, iPad, and iPod touch ...
  2. Batteries - Maximising Performance - Apple (IN)
  3. iPhone Battery and Performance



Try to monitor Battery usage by iPhone Activity as shown below


What is shown under battery usage? Checking that would give you an indication of the usage behavior.

  1. Background Activity
  2. Notifications
  3. Connected to Charger
  4. Or any Other


See the pic below (iPhone 12 Pro iOS 17.3.1)


"Show Activity" feature will show you more info see the pic below




Try some of these options too.

All of the great information above can probably be boiled down to "Turn on optimized charging, put your phone on charge overnight and stop worrying about it."


Your battery will lose capacity over time. You can't stop that. When it drops below 80%, you have it replaced (if you're not ready to buy a new phone).

There are always going to be different opinions about the "best" way to do something.


Here is what has worked extremely well for me with every iPhone that I have always owned.


  • Enable Optimized Battery Charging
  • Connect the phone to the power adapter at night and leave it connected all night.....every night
  • Ignore Charge Limit settings.....if they are an option on your phone
