Understanding Controller Batteries
Learn about battery types and how to maximize battery life
Battery Types
Modern controllers use different battery technologies with varying characteristics.
- Li-ion: PS5, PS4, Switch Pro (built-in)
- AA Batteries: Xbox controllers (replaceable)
- Li-Po: Some third-party controllers
- Rechargeable packs: Xbox battery packs
Battery Life Expectations
Typical battery life varies by controller and usage patterns.
- PS5 DualSense: 12-15 hours
- PS4 DualShock 4: 4-8 hours
- Xbox Series: 30-40 hours (AA)
- Switch Pro: 40 hours
Saving Battery Tips
Simple ways to extend your controller's battery life.
- Lower LED brightness/turn off
- Reduce vibration intensity
- Disable adaptive triggers (PS5)
- Turn off when not in use

Battery Care Tips
Best practices for maintaining controller battery health
Avoid Extreme Temps
Keep controllers away from extreme heat or cold. Store between 50-77°F (10-25°C) for optimal battery life.
Partial Charges OK
Li-ion batteries don't need full discharge cycles. Charging between 20-80% can extend overall lifespan.
Turn Off When Done
Don't leave controllers on standby. Turn them off completely when not gaming to preserve battery.
Use Quality Cables
Use manufacturer-recommended or quality USB cables. Poor cables can damage batteries over time.
Regular Use
Use and charge controllers regularly. Long periods of storage without use can degrade batteries.
Don't Overcharge
Most controllers have overcharge protection, but unplugging after full charge is still good practice.
Frequently Asked Questions
Common questions about controller batteries
Why doesn't my battery level show up?
+Battery level reporting depends on your controller, browser, and connection method. Try connecting via Bluetooth instead of USB, as many controllers only report battery over Bluetooth. Also ensure you're using a modern browser like Chrome, Edge, or Firefox that supports the Gamepad API battery extensions.
How accurate is the battery reading?
+The accuracy depends on how the controller reports battery data. Some controllers report exact percentages while others report in steps (100%, 75%, 50%, 25%). The reading comes directly from your controller's battery management system, so it's as accurate as what the controller itself reports.
Can I check battery while charging?
+It depends on the controller. PlayStation controllers can report battery while charging via USB if connected as a Bluetooth device. Xbox controllers may not report battery when connected via USB. The charging indicator will show when your controller is receiving power.
How do I replace my controller battery?
+Xbox controllers use standard AA batteries or rechargeable battery packs that are easy to replace. PlayStation and Nintendo controllers have built-in Li-ion batteries that require opening the controller - this can void warranty and should be done carefully or by a professional. Third-party replacement batteries are available online.
Why does my PS5 controller battery die so fast?
+The PS5 DualSense has many power-hungry features: adaptive triggers, haptic feedback, built-in speaker, microphone, and LED light bar. To extend battery life, go to Settings > Accessories > Controllers and reduce/disable adaptive triggers intensity, haptic feedback, and dim the light bar brightness.
Is it bad to play while charging?
+Playing while charging is generally safe for modern controllers with proper charging circuits. However, it can generate more heat which may slightly reduce long-term battery lifespan. If your controller gets noticeably hot while charging and playing, consider taking breaks to let it cool down.
