iPhone 15 ProMax battery started draining faster

I have had my 15 ProMax since the day it was launched, and was happy with the battery life. As advertised, 1-2 days of normal use. Then suddenly, around 4 days ago, the battery started draining for nothing. I thought it was an app that I had just downloaded, so I went as far as to factory reset everything. Battery is still bad.

Notice that my battery health is still at 100%, and this happened basically overnight. I come from a 3 year old iPhone 12 mini and my battery now is worse than the old phone. I left my house at 40%, got on the bus, did a couple of google searches, typed this text, and 9 minutes later I am at 32%. Normally this would’ve taken 1% if any at all.

What is happening? Anyone else going through something similar?

31% now…

When you go to Settings/Battery what apps are using the most energy? Battery drain means something is using energy, and the only things that use energy are maintaining a cellular connection and apps, so if it isn’t the cellular network then the only remaining possibility is apps.

As it started 3 days ago I would suspect a cellular network outage; have you checked with your carrier?

You should be charging your phone overnight every night, with Automatic Backups enabled, as recommended by Apple.

As far as battery drain is concerned, weak cellular network signals (1 or 2 bars) can use a lot of energy. If you go to Settings/Battery it will show which apps use the most energy.

Lawrence I haven’t changed the area where I live. I have 5 bars the entire day everywhere. I also charge it overnight only, but this hasn’t been something cumulative. It started happening literally 3 days ago. I also thought it could be an app but all the apps I have are the normal regular use (instagram, mail, messages) the same way I have been using them since I got my phone, and there seems to be nothing strange app wise. Also no iOS updates three days ago…
