Fix iPhone 14 Battery Draining Fast on AT&T

 If your iPhone 14 battery drains faster than usual — especially on AT&T’s network — you can fix it by checking settings, apps, and background connections. Here’s what to do step by step.

1. Why the Battery Drains Fast

Several factors can cause quick battery drain:

  • 5G connectivity constantly switching between bands

  • Background app refresh using mobile data

  • Location services running all the time

  • High display brightness and always-on screen

  • Recent iOS updates still optimizing in the background

2. Quick Fixes to Try First

  1. Restart your iPhone 14 — this clears temporary network and app glitches.

  2. Update iOS: Go to Settings → General → Software Update.

  3. Check AT&T signal strength — poor coverage makes your phone use more power.

  4. Lower screen brightness or disable Always-On Display (Settings → Display & Brightness).

3. Optimize Battery Settings

  • Go to Settings → Battery → Battery Health & Charging.
    Turn on Optimized Battery Charging.

  • In Battery Usage, check which apps drain the most and restrict them.

  • Turn off Background App Refresh under Settings → General.

  • Disable Location Services for apps that don’t need it (Settings → Privacy).

4. AT&T Network Tips

If battery drain happens mostly on AT&T’s mobile data:

  • Switch to LTE instead of 5G temporarily (Settings → Cellular → Voice & Data → LTE).

  • Ensure Wi-Fi Calling is enabled to reduce radio use indoors.

  • Reset Network Settings if needed: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.

OnePlus Tip

After major iOS or carrier updates, your iPhone might use extra power for a day or two while re-indexing data — this is normal. If the issue continues longer, contact AT&T or Apple Support to check for carrier-specific power management updates.
