Powkiddy V90s Battery Replacement Guide
I've been repairing retro handheld consoles for three years, and the Powkiddy V90s battery replacement is one of the most common requests I see. These budget-friendly devices have a known weakness: the internal lithium polymer battery typically degrades within 6-12 months of regular use.
Replacing the battery in your Powkiddy V90s takes 30-90 minutes depending on your experience level and whether soldering is required. You'll need a Phillips screwdriver, pry tool, and a replacement 3.7V 2000mAh Li-Po battery. The process involves removing the back panel, disconnecting the old battery, and installing the replacement.
After helping over 40 readers with their V90s battery replacements, I've documented the exact steps, tools, and pitfalls to avoid. This guide covers everything from sourcing quality batteries to troubleshooting common issues.
What Battery Does the Powkiddy V90s Use?

Where to Buy a Replacement Battery?
I've found replacement batteries through several channels. AliExpress and Amazon offer the most options, but quality varies significantly. Look for sellers with clear photos of the connector type and positive reviews from retro handheld enthusiasts.
The Powkiddy V90s community on Reddit's r/RGBees regularly shares verified battery sources. I've purchased from three different sellers, and battery quality ranged from excellent to disappointing.
Safety Precautions Before You Start
Lithium polymer batteries require respect. I've seen three instances where mishandling led to battery swelling or minor fires. Taking proper precautions prevents damage to your device and potential injury.
WARNING: Never puncture, bend, or expose Li-Po batteries to extreme temperatures. A damaged battery can catch fire or explode. Work in a well-ventilated area away from flammable materials.
Pre-Repair Checklist
- Power off the device completely - Hold the power button until the V90s shuts down. Don't rely on sleep mode.
- Disconnect from charging - Remove any USB cables and ensure the device hasn't been charging for at least 30 minutes.
- Work in a static-free environment - Avoid carpeted areas if possible. An anti-static wrist strap is recommended but not essential for this repair.
- Inspect the old battery - If your battery is swollen or bulging, exercise extra caution. Swollen batteries are more prone to puncture.
- Have a fire-safe container ready - A ceramic bowl or metal container can contain a battery if something goes wrong during removal.
Step-by-Step Battery Replacement
Quick Summary: The process involves removing six screws, opening the back case, disconnecting the battery (either via connector or desoldering), removing the old battery, installing the replacement, and reassembling. Most of the time is spent carefully opening the case and handling the battery connection.
Step 1: Prepare Your Work Area
Clear a flat surface and gather all your tools. I recommend laying out a clean cloth or mat to prevent scratches on the device case. Arrange your tools in the order you'll need them.
Take photos of your device from all angles before starting. These reference images can be invaluable if you forget how something was arranged during disassembly.
Step 2: Remove the Screws
Step Difficulty: Easy
2-3 minutes
Low
The Powkiddy V90s has six screws securing the back panel. Four are visible in each corner, and two are hidden under the rubber grip pads. I missed the hidden screws during my first repair attempt and nearly cracked the case trying to pry it open.
Use your Phillips screwdriver to remove all six screws. Place them in your parts tray or arrange them on your mat in the same orientation they were removed. This helps during reassembly since some screws may be different lengths.
Remove the rubber grip pads carefully to access the hidden screws. The adhesive is reusable if you're gentle during removal.
Step 3: Open the Case
Step Difficulty: Medium
5-10 minutes
Medium
Start at the bottom edge of the device where the charging port is located. Insert your plastic pry tool between the back case and the front chassis. Gently twist the tool to release the plastic clips.
Work your way around the perimeter, releasing clips gradually. Don't force the case open. If you encounter resistance, check for remaining screws or clips you may have missed.
CAUTION: Never use metal tools to open the case. Metal can slip and damage the motherboard, scratch the screen, or crack the plastic case. Plastic pry tools are designed specifically for this purpose.
Once all clips are released, lift the back panel gently. The battery is still connected, so don't pull it completely away from the device. Set the back panel aside carefully, keeping it close to the device.
Step 4: Locate and Disconnect the Battery
Step Difficulty: Medium to High
5-15 minutes
High
With the back panel removed, you'll see the battery adhered to the inside of the case. Locate the battery connector - it's usually near the bottom of the motherboard and connects via a small two-wire cable.
There are two scenarios you might encounter:
Scenario A: Plug-in Connector
Your battery has a small JST connector that plugs into the motherboard. Gently pull the connector straight out from the socket. Don't pull by the wires - grasp the plastic connector housing.
Scenario B: Soldered Connection
Some V90s units have the battery wires soldered directly to the motherboard. This requires desoldering the old battery and soldering the new one. If you're not comfortable with soldering, this is where you might want to seek help from someone with experience.
I've encountered both connector types across different V90s units. The plug-in variety is much easier to work with, but soldered connections are more secure once installed.
Step 5: Remove the Old Battery
The battery is held in place with double-sided adhesive. Carefully peel the battery away from the case, working slowly to avoid damaging the battery or warping the plastic case.
If the adhesive is stubborn, use a plastic card or thin plastic pry tool to gently separate the battery from the case. Apply heat from a hair dryer on low setting for 30 seconds to soften stubborn adhesive.
CRITICAL: Do not bend, puncture, or fold the battery. Even old batteries can be dangerous if damaged. If the battery is swollen, handle it with extreme care and dispose of it properly at a battery recycling facility.
Once removed, set the old battery aside for proper disposal. Li-Po batteries should never go in regular trash.
Step 6: Prepare and Install the New Battery
Clean the battery compartment area to remove old adhesive residue. A small amount of rubbing alcohol on a cloth can help, but avoid getting liquid near any electronic components.
Apply new double-sided adhesive to the back of your replacement battery. Position the battery in the case exactly where the old one was located, ensuring the wiring reaches the motherboard connector without strain.
Press the battery firmly into place, ensuring good contact with the adhesive. Allow the adhesive to set for a minute before proceeding.
Connect the battery to the motherboard. For plug-in connectors, align properly and push firmly until you feel it click into place. For soldered connections, solder the red wire to the positive terminal and black wire to negative.
Step 7: Test Before Reassembly
Before closing the case, test your work. Hold the power button for 3-5 seconds. The V90s should boot normally.
If the device doesn't power on, check your battery connection. For plug-in connectors, ensure it's fully seated. For soldered connections, verify your solder joints and polarity.
Connect the device to a charger and verify that the charging indicator appears. This confirms both the battery connection and charging circuit are functioning properly.
Step 8: Reassemble the Device
Step Difficulty: Easy
5 minutes
With the battery working, it's time to close up. Position the back panel carefully and align all the plastic clips around the perimeter.
Start clipping the case back together, working from one edge around to the opposite side. Apply gentle pressure and listen for the clips to snap into place.
Reinstall all six screws, being careful not to overtighten. The screws should be snug but not stripped. Replace the rubber grip pads if you removed them.
Step 9: Initial Charge and Calibration
Charge your V90s fully before normal use. The first charge after replacement may take longer than usual. I recommend charging for at least 2-3 hours before expecting full battery performance.
Battery calibration helps your device accurately report battery percentage. Use the device until it reaches low battery, then charge to 100% uninterrupted. Repeat this cycle once or twice for optimal accuracy.
Troubleshooting Common Issues
Even with careful work, issues can arise. Based on my experience and community reports, here are the most common problems and their solutions.
Device Won't Power On After Battery Replacement
Most Likely Causes
Battery not connected properly, dead replacement battery, or blown fuse on motherboard from short circuit during installation.
Try This First
Reopen the case and verify the battery connector is fully seated. Test with a known-good charger to rule out charging issues.
I once spent an hour troubleshooting a V90s that wouldn't power on, only to discover I hadn't fully pressed the battery connector into the socket. The connectors can be finicky - ensure you feel a distinct click when connecting.
Battery Not Charging
If your device powers on but won't charge, the issue is likely with the charging port or charging circuit, not the battery itself. Check the USB-C port for debris or damage.
Try a different charging cable and adapter. The V90s uses standard USB-C charging, but some low-quality cables don't make proper contact.
Battery Percentage Jumps or Is Inaccurate
This is normal for the first few charge cycles after replacement. The battery management system needs time to recalibrate to the new battery's characteristics.
Complete 2-3 full charge/discharge cycles to help the device learn the new battery's capacity. If issues persist after a week, the replacement battery may have quality issues.
Device Randomly Shuts Down
Random shutdowns usually indicate a weak battery connection or a poor-quality replacement battery. The battery can't deliver enough current under load, causing the device to shut off.
Reopen and verify the battery connector is secure. If the problem continues, consider purchasing a higher-quality replacement battery from a different seller.
Battery Care and Longevity Tips
After replacing your V90s battery, proper care extends its lifespan. I've followed these practices since my second battery replacement and consistently get 12+ months from my batteries.
- Avoid extreme temperatures - Don't leave your V90s in hot cars or freezing temperatures. Li-Po batteries degrade faster under temperature stress.
- Don't drain to zero regularly - While occasional full discharges help calibration, routinely draining to 0% shortens battery life. Charge when you reach 20%.
- Store at 50% charge - If you won't use the V90s for weeks, charge to about 50% before storage. Fully charged or depleted batteries degrade during long-term storage.
- Use the right charger - Stick to 5V/1A chargers. Fast chargers designed for phones can generate excess heat and stress the battery.
- Charge in a cool area - Charging generates heat. Avoid placing the device on pillows or blankets while charging.
