How to Fix Asus Zenfone 10 With Rapid Battery Drain

If your Asus Zenfone 10 battery is draining faster than usual, the problem is usually caused by apps, screen settings, weak signal, background activity, location access, or a recent software update.

The Zenfone 10 has a 4300mAh battery, supports 30W wired charging, and also supports wireless charging, so it should not lose power quickly during light use unless something is running harder than normal.

Start with the simple checks first. Look at battery usage, restart the phone, update apps, then adjust the settings most likely to drain power.

Quick answer

If your Asus Zenfone 10 battery is draining fast, go to Settings > Battery and check which apps are using the most power. If one app is unusually high, update it, restrict its background activity, or uninstall it temporarily.

Then check display brightness, refresh rate, 5G/mobile signal, location access, background syncing, and power-saving settings. ASUS recommends using power-saving modes and adjusting battery settings to extend battery life.

If the battery drain started after an update, restart the phone, update your apps, and monitor the battery for 24 to 48 hours before doing bigger fixes.

Why is my Asus Zenfone 10 battery draining so fast?

Your Asus Zenfone 10 may be draining quickly because something is using more power than normal.

Common causes include:

Apps running in the background
High screen brightness
High refresh rate
Weak mobile signal
5G usage
Location services
Bluetooth, hotspot, or Wi-Fi scanning
Background syncing
Recent app or Android updates
Battery aging or hardware issues

This does not always mean the battery is faulty. Most battery drain problems are caused by settings or apps, not the battery itself.

1. Check battery usage by app

Start here because this tells you what is actually using power.

1. Open Settings.
2. Tap Battery.
3. Check Battery usage.
4. Look for apps using more battery than expected.
5. Tap the app and review its background activity settings.

Look for apps that appear high on the list even though you barely used them.

Pay attention to:

Social media apps
Shopping apps
Navigation apps
Camera apps
Games
Video streaming apps
Messaging apps
VPN apps
Fitness or tracking apps

If one app stands out, update it first. If that does not help, restrict its background activity or uninstall it for a day to see whether battery life improves.

2. Restart your Asus Zenfone 10

A restart is simple, but it can fix temporary battery drain caused by stuck apps or system processes.

1. Press and hold the Power button.
2. Tap Restart.
3. Wait for the phone to turn back on.
4. Use it normally for a few hours.
5. Check if the battery drain slows down.

This will not delete your files, photos, apps, or settings.

Restarting is especially useful if the battery drain started suddenly, the phone feels warm, or an app recently froze.

3. Update your apps and system software

Outdated apps can cause battery drain, especially if they keep running in the background or fail to sync properly.

To update apps:

1. Open the Google Play Store.
2. Tap your profile icon.
3. Tap Manage apps and device.
4. Tap Update all.

To update your phone:

1. Open Settings.
2. Tap System.
3. Tap System update.
4. Install any available update.

Battery drain can sometimes happen after a major software update. The phone may need time to optimise apps, refresh services, and rebuild background processes.

Use the phone normally for 24 to 48 hours after updating. If the drain continues after that, move to the next fixes.

4. Lower brightness and adjust display settings

The display is one of the biggest battery users on any phone. On the Zenfone 10, this matters even more if you keep brightness high or use a high refresh rate all day.

Start with brightness:

1. Open Settings.
2. Tap Display.
3. Lower the brightness slider.
4. Turn on adaptive brightness if you prefer automatic adjustment.

Then reduce screen timeout:

1. Open Settings.
2. Tap Display.
3. Tap Sleep or Screen timeout.
4. Choose a shorter time, such as 30 seconds or 1 minute.

Next, check refresh rate:

1. Open Settings.
2. Tap Display.
3. Look for refresh rate or smooth display settings.
4. Use an automatic or lower refresh rate option if battery life matters more than maximum smoothness.

A high refresh rate makes scrolling feel better, but it can use more power. If your battery drops quickly while the screen is on, display settings are one of the first things to adjust.

5. Turn on battery saver or ASUS power-saving mode

The Zenfone 10 includes battery-saving options that can reduce background activity and help the phone last longer.

1. Open Settings.
2. Tap Battery.
3. Look for Power saving or battery-saving options.
4. Turn on the power-saving mode.
5. Set it to turn on automatically at a low battery percentage.

ASUS recommends using power-saving modes to extend phone battery life when needed.

Use this when you are travelling, working away from a charger, or noticing rapid drain during standby.

Power-saving mode may reduce background updates, limit performance, delay notifications, or lower some visual effects. That is normal.

6. Check mobile signal and 5G usage

Weak signal can drain battery fast. When your Zenfone 10 struggles to stay connected, it uses more power searching for a better network.

This often happens:

Inside buildings
In basements
Inside elevators
In rural areas
While travelling
In areas with patchy 5G coverage

If your battery drains faster on mobile data than Wi-Fi, test a lower network mode.

1. Open Settings.
2. Tap Network & internet.
3. Tap Mobile network.
4. Look for preferred network type.
5. Switch from 5G to 4G/LTE temporarily.

Use the phone for a few hours and compare the drain.

If battery life improves on 4G/LTE, the issue may be weak 5G coverage in your area rather than the phone itself.

7. Limit location access for apps

Location access can drain battery when apps keep checking your position in the background.

1. Open Settings.
2. Tap Location.
3. Tap App location permissions.
4. Review which apps can access location.
5. Change non-essential apps to Allow only while using the app or Don’t allow.

Keep location access for apps that truly need it, such as maps, ride-hailing, weather, and delivery apps.

Be stricter with apps that do not need constant location access, such as shopping apps, social apps, games, and photo editing apps.

Also check whether an app is using precise location when approximate location is enough.

8. Turn off hotspot, Bluetooth, and scanning when not needed

Some wireless features can use battery even when you are not actively thinking about them.

Check these settings:

Wi-Fi hotspot
Bluetooth
Nearby device scanning
Wi-Fi scanning
Bluetooth scanning
NFC
VPN

To check hotspot:

1. Open Settings.
2. Tap Network & internet.
3. Tap Hotspot & tethering.
4. Turn off hotspot if you are not using it.

To check Bluetooth:

1. Open Settings.
2. Tap Connected devices.
3. Turn off Bluetooth if you do not need it.

To check scanning:

1. Open Settings.
2. Tap Location.
3. Tap Location services.
4. Check Wi-Fi and Bluetooth scanning options.

You do not need to turn everything off forever. Just turn off features you are not using, especially when battery life matters.

9. Restrict background activity for problem apps

Some apps keep syncing, refreshing, tracking, or sending notifications in the background. This can drain battery even when the screen is off.

1. Open Settings.
2. Tap Apps.
3. Select the app causing battery drain.
4. Tap Battery.
5. Choose a restricted or optimized option if available.

Use this for apps that do not need instant updates.

Good candidates include:

Shopping apps
Travel apps
Food delivery apps
Games
Streaming apps
Photo editing apps
Old apps you rarely open

Be careful with messaging, email, banking, calendar, and work apps. Restricting them too much may delay notifications.

10. Reset settings or contact ASUS support if nothing works

If your Asus Zenfone 10 still drains quickly after trying the fixes above, reset settings before assuming the battery is bad.

Start with network settings if the drain is worse on mobile data or Wi-Fi:

1. Open Settings.
2. Tap System.
3. Tap Reset options.
4. Tap Reset Wi-Fi, mobile & Bluetooth.

This removes saved Wi-Fi networks, Bluetooth pairings, and mobile network preferences. It does not delete your photos or apps.

If the battery still drains fast, back up your phone and consider a full reset.

You should contact ASUS support if:

The phone gets hot even when idle
The battery drops suddenly by large percentages
The phone shuts down before reaching 0%
The battery drains fast in Safe Mode
The phone is swollen, bent, or physically damaged
Charging behaves strangely with multiple chargers

Do not ignore swelling, overheating, or sudden shutdowns. Those can point to a battery or hardware problem.

What to do if battery drain started after an update

If your Zenfone 10 started draining after a software update, do not panic right away.

Try this order:

1. Restart the phone.
2. Update all apps.
3. Charge the phone fully.
4. Use it normally for 24 to 48 hours.
5. Check battery usage again.
6. Remove or restrict any app that appears unusually high.

After an update, apps and system services may run extra tasks in the background. If the drain continues after two days, it is more likely that an app, setting, or software bug needs attention.

Best settings to reduce Asus Zenfone 10 battery drain

Use these settings if you want a quick battery-friendly setup:

Lower screen brightness
Use shorter screen timeout
Use automatic or lower refresh rate
Turn on power-saving mode
Restrict unused apps
Limit location access
Use 4G/LTE in weak 5G areas
Turn off hotspot when not needed
Update apps regularly
Restart the phone once in a while

This setup keeps the phone usable without making it feel too limited.
