How to Fix Battery Drain Overnight (Step-by-Step)

✅ 1. Turn On Battery Saver Before Sleeping

Battery Saver limits background activity and reduces power consumption.

👉 Go to:

Settings → Battery → Battery Saver → Turn it on

This alone can significantly reduce overnight drain.

✅ 2. Check Battery Usage (Find the Culprit)

Some apps secretly drain battery even when not in use.

👉 Go to:

Settings → Battery → Battery Usage

Look for:

• Apps using high battery overnight
• Apps you didn’t even open

If you find one → restrict or uninstall it.

✅ 3. Restrict Background Apps

👉 Go to:

Settings → Apps → Select App → Battery → Restrict

Do this especially for:

✅ 5. Enable Airplane Mode (Best Trick)

This is one of the most effective solutions.
