iPhone 15 pro max battery does not last very long

Greetings marlam50,

To help isolate why the battery may not be lasting as long as expected, check if a specific app is using more battery than what you'd expect. To do so, tap Settings > Battery, then scroll down to view the battery usage by app. Check out that suggestion, and further troubleshooting steps, in the following article: Batteries - Maximizing Performance - Apple

Kind regards.

Same issue my battery does not last long at all. If i do a video it will eat it up. I play a game have to charge it within an hour. Its horrible
