1. Find Out What’s Actually Draining the Battery
Before fixing anything, figure out what’s causing the issue.
Go here first:
Settings > Battery
Check:
- Battery usage graph
- Screen-on time
- App battery consumption
You might spot one or two apps draining way more battery than expected.
Common battery drain culprits on Nothing Phone 2a:
- Glyph Interface is always active
- Always On Display running full-time
- 120Hz refresh rate enabled
- 5G is constantly active
- Social media apps are refreshing in the background
You can also check battery health:
Settings > System > Device Diagnostics > Component Health > Battery Status
This helps you see battery health percentage and charge cycles.
You can also use apps like:
- AccuBattery
- Ampere
These give more detailed battery stats after a few charging cycles.
If battery health is under 80–85 percent, battery aging could be a major reason behind your Nothing Phone 2a battery problem.

Software updates often include battery optimization improvements.

3. Optimise Settings for Better Battery Life
This is where most users see the biggest improvement. A few tweaks can easily add 1 to 2 extra hours of battery life.
Reduce Always On Display Usage
AOD looks cool, but it quietly drains battery.
Go to Display settings and:
- Turn it off completely, or
- Set it to Tap to show
That alone can make a noticeable difference.
Limit Glyph Interface
Let’s be honest, the Glyph lights are fun, but they’re not exactly battery-friendly.
Go to Glyph settings and:
- Reduce notification lights
- Disable unnecessary charging animations
Small change, surprisingly helpful.
Adjust Display Settings
Try these:
- Lower brightness or enable adaptive brightness
- Change refresh rate from 120Hz to 60Hz
- Reduce screen timeout to 15 to 30 seconds
High refresh rate feels smoother, but battery pays the price.

4. Manage Connectivity Better
Your network settings can drain battery more than expected.
A few smart changes:
- Switch to 4G instead of 5G if you don’t really need 5G
- Turn off:
- Bluetooth
- Wi-Fi
- Location when not in use
These background services love sipping battery all day.
5. Restrict Background Apps
Some apps are battery vampires.
To control them:
Settings > Apps > [Select App] > Battery > Restricted
Do this for apps you don’t need running all the time.
Also:
- Uninstall unused apps
- Check Digital Wellbeing for screen and app activity
Sometimes the problem is less “bad battery” and more “too many apps doing drama in the background.”

A few important tips:

Dust buildup can cause slow or inconsistent charging.
Safely clean using:
- Compressed air
- Soft wooden toothpick
Avoid metal pins or aggressive poking.
Charge Smarter
Try not to:
- Let the battery hit 0 percent regularly
- Keep the phone plugged in at 100 percent for hours
Best charging range: 20 percent to 80 percent. Not always practical, but healthier long-term.
7. Try Battery Calibration
If the battery percentage feels inaccurate, calibration can help.
Do this occasionally:
- Drain battery to 5 to 10 percent
- Charge uninterrupted to 100 percent
- Leave plugged in for 1 to 2 extra hours
- Use normally
This can improve battery percentage accuracy.
