If one app is using far more battery than expected, updating or reinstalling it may solve the issue.

Check iPhone 17e Battery Health

Apple includes Battery Health monitoring to help determine whether battery aging is responsible.

Navigate to:

Settings → Battery → Battery Health

Pay attention to:

Maximum Capacity

This indicates how much charge the battery can still hold compared to when it was new.

Peak Performance Capability

If iOS reports that performance management has been applied, the battery may no longer supply stable power during demanding tasks.

Most new iPhone 17e devices should maintain excellent battery health. However, defective batteries or unusually heavy charging habits can accelerate wear.

Reduce Background App Activity

Many apps continue working even when you’re not actively using them.

These background processes include:
