Fast Draining Battery

Hi,


I bought my iPhone 13 Pro Max 128GB last November 2021. Since that time its battery could last upto 3 days with 30%-40% left. But just this recently it's draining to fast as if it lasts nearly 2 days and that's on standby for most of the time. Just last night I went to sleep the battery is 90% charged but when I woke up after 6 hours of sleep it's down to 60%.


I have done some advices seen online like turning off certain apps and settings but it's still fast. I even tried disconnecting it from the paired Apple Watch by switching off the latter but it still drain so fast.


Here are some other facts:

  1. Software version 15.2.1
  2. All apps completely shut off
  3. Not so much apps (FB, Messenger, Viber, Mail)


What should I do? Any advice?

iPhone 13 Pro Max, iOS 15

Hello,

I would guess that you could have a rogue app running in the background. See this:

Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.

Note: it is considered a best-practice to charge the phone all-night every night. It gives you the follow advantages:

  1. You start the new day with a fully charged phone
  2. iCloud backups occur automatically (assuming a Wi-Fi connection)
  3. Software updates occur automatically (assuming a Wi-Fi connection)
  4. If something bad happens overnight, you know where your phone is and it is at least partially charged

Good luck.

Three days is not to be expected under normal usage, nor to be frank is two between charges even on what you describevas Standby.

You should not leave any iphone, especially one as powerful as the 13, off charge overnight. All the housekeeping processes are designed for overnight, locked, and on charge.
