Apps not updated for the new OS version

Enabled the new features (location scanning, animations, etc.)

Bugs in the update

Battery calibration issue

Cache/data corruption

 

1. Restart Your Phone

Why it helps: A fresh reboot clears temporary files and restarts all the services. After an update, your phone might still be optimizing apps in the background.

 

2. Check Battery Usage & Spot Draining Apps

Go to the:

Settings → Battery → Battery Usage

Check:

Any app using over 10% when not in active use

Google Play Services, Facebook, or system apps draining unusually high

Tap the app and select Force Stop or Restrict background activity

 

3. Clear Cache Partition (Important After Update)

Clearing the cache partition removes leftover files from the old OS, which may conflict with the new one.

Steps:

1. Power off your device

2. Press Power + Volume Up (varies by model) to enter recovery mode

3. Use volume keys to select Wipe Cache Partition

4. Confirm and reboot

No personal data is lost.

 

4. Use Battery Saver Mode

Turn it on manually or schedule it at 30% battery.

Settings → Battery → Battery Saver

Restrict background for apps you rarely use:

Steps:

Settings → Apps → Select App → Battery → Restrict Background Usage

You can keep important accounts synced like Gmail but disable others.

Turn off Adaptive Brightness

Set screen timeout to 15–30 seconds

Use dark mode

Sometimes after an update, the battery stats may be inaccurate.

Steps:

1. Fully charge your phone to 100%

2. Use it until it shuts off at 0%

3. Charge to 100% without interruption

4. Repeat 2–3 times

This helps the system recalibrate actual battery capacity.
