The GX 2 Pro shows a full charge through its LED indicator and battery percentage

The GX 2 Pro is a portable gaming device made by Anbernic. When it is fully charged, the LED light on the device turns green or stops blinking, and the battery percentage on the screen reads 100%. The exact indicator depends on which version you own — some models show a solid green light, while others display a steady blue light. The quickest way to check is to look at the battery icon in the top corner of the screen while the device is powered on.

Charging time varies based on the power adapter you use. With the standard USB-C charger that comes in the box, a full charge typically takes 3 to 4 hours from completely empty. Using a higher-wattage charger can reduce this time, but the device will only draw the power it needs, so faster chargers do not damage the battery.

You can use the GX 2 Pro while it charges, though this slows down the charging process. The battery will still reach 100%, but it may take an extra 30 minutes to an hour if you are actively playing games or running other programs.

Key Takeaways

  • The LED indicator on the GX 2 Pro turns green or blue when fully charged, depending on your model version.
  • The battery percentage on the home screen or in the status bar will show 100% when charging is complete.
  • A full charge from empty takes 3 to 4 hours with the standard USB-C charger included with the device.
  • Using the device while charging slows the process but does not prevent the battery from reaching full capacity.

Understanding the LED light on your GX 2 Pro

The LED indicator is the fastest way to know your charge status without turning on the screen. On most GX 2 Pro models, the light is located near the charging port or on the side of the device. When you first plug in the charger, the light will blink or glow red or orange, signaling that charging is in progress.

As the battery fills, the light may change color or stop blinking. When the light turns solid green or solid blue — depending on your specific model — the device has reached 100%. Some versions of the GX 2 Pro turn off the LED entirely once fully charged, so check your device manual if you are unsure which behavior yours displays.

If the LED does not change color after several hours, the charger may not be making a proper connection. Try unplugging and replugging the USB-C cable, or test the charger with another device to rule out a faulty cable.

Checking the battery percentage on the screen

The most reliable way to confirm a full charge is to look at the battery percentage displayed on your GX 2 Pro. This number appears in the top-right corner of the home screen or in the status bar, depending on which menu you are viewing. When the percentage reads 100%, your device is fully charged.

You do not need to turn on the device to see this information — many GX 2 Pro models display the battery level on the lock screen or charging screen as well. This is useful if you want to check progress without waking the full interface.

The battery percentage is more accurate than the LED light alone, because the light can sometimes turn green before the device has truly reached 100%. If the light is green but the percentage shows 99%, leave the charger connected for a few more minutes.

How long a full charge actually lasts

Once your GX 2 Pro reaches 100%, how long that charge lasts depends on what you are doing. Playing demanding games like emulated Nintendo 64 or Dreamcast titles drains the battery faster than playing older 8-bit games or watching videos. Most users report 4 to 6 hours of mixed use — some gaming, some menu browsing, some idle time.

If you play continuously without breaks, expect 3 to 5 hours before the battery drops to 20%. Lighter use, like navigating menus or playing turn-based games, can stretch a full charge to 7 or 8 hours.

Battery health degrades over time with repeated charging cycles. After 1 to 2 years of regular use, you may notice the device does not hold a charge as long as it did when new. This is normal for lithium batteries and does not mean the device is broken.

Troubleshooting when the GX 2 Pro will not charge to 100%

If your device stops charging before reaching 100%, the most common cause is a loose USB-C connection. The port on the GX 2 Pro can become loose over time, especially if the cable is pulled at an angle. Try different angles when plugging in the charger, or gently clean the port with a dry cloth to remove dust or lint.

A second common issue is using a charger with insufficient power output. The GX 2 Pro needs at least 2 amps of current to charge properly. Phone chargers often provide only 1 amp, which means the device may charge very slowly or not at all if the battery is being used while plugged in. Check your charger's specifications — it should say "2A" or higher on the label or in the manual.

If the device charges to 99% but never reaches 100%, this is usually not a hardware problem. Some devices intentionally stop at 99% to extend battery lifespan, or the final 1% may take an unusually long time. Leave the charger connected for 30 minutes after the percentage stops climbing.

Caring for your battery to maintain full charge capacity

Lithium batteries perform best when they are not kept at 100% constantly. If you charge your GX 2 Pro to full and then leave it plugged in for days, the battery will degrade faster than if you unplug it after reaching 100%. Once the device is fully charged, disconnect the charger.

Avoid letting the battery drop to 0% regularly. Charging when the device reaches 20% to 30% is gentler on the battery than waiting until it shuts down completely. If you store the GX 2 Pro for more than a month, charge it to about 50% before putting it away — this is the ideal storage level for lithium batteries.

Heat damages batteries, so keep your GX 2 Pro away from direct sunlight and warm environments while charging. Charge in a cool room when possible, and do not cover the device with blankets or place it in a closed bag while the charger is connected.

Frequently Asked Questions

Can I leave my GX 2 Pro plugged in overnight?

Yes, it is safe to leave the device plugged in overnight. Most modern devices, including the GX 2 Pro, have built-in protection that stops charging once the battery reaches 100%. However, leaving it plugged in constantly will shorten the battery's lifespan over months or years. Unplug after it reaches full charge when possible.

What does it mean if the LED light is blinking red?

A blinking red light means the device is charging and the battery is still below 100%. This is normal. Once the light turns solid green or blue, the charge is complete. If the light blinks red for more than 5 hours without changing, the charger may not be working properly.

Why does my GX 2 Pro charge slower than it used to?

Older batteries naturally charge more slowly as they age. Dust or lint in the USB-C port can also slow charging. Try cleaning the port gently with a dry cloth. If the device is warm while charging, let it cool down — batteries charge faster at room temperature.

Is it bad to use my GX 2 Pro while it is charging?

Using the device while charging is safe but slows the charging process. The battery will still reach 100%, but it may take 30 minutes to an hour longer. If you need a quick charge, turn off the device or put it in sleep mode while plugged in.

How do I know if my charger is broken?

Test the charger with another USB-C device if you have one available. If that device charges normally, your charger is fine and the issue is with the GX 2 Pro's port. If the other device also will not charge, the charger is likely faulty and needs replacement.
