Why is my iPhone 16 Pro Max battery draining so fast?

Hi everyone,


Has anyone noticed their 16 pro max battery draining quicker than it should? Got the phone on launch day, under Settings>Battery it mentioned some updates running in the background may affect battery and thermal performance so I waited. Now that the message is gone, I still notice the battery draining quicker than usual.

My phone used to drain battery rapidly even when it was idle, and I couldn’t figure out why. A friend recommended this guide 11 Proven Steps to fix iPhone 16 Pro Max Battery Drain Issue. I followed their tips, turning off few features that I didn’t need to be running in background, especially background apps like the weather and map widgets. Now, I’m seeing a noticeable improvement in my battery life! You should try them aswell.

I was testing if an app is doing this but to no avail, the iPhone 16 pro is still drawing pretty fast, in the specs they show some battery performance similar to the 13 pro max but, of course, my 13 pro max still has this amazing battery life… I don’t know if should I wait for the 18.1 update or send it to warranty, because AT&T does not accept returns.
