Apple iPod Touch 4th Gen Replacement Battery 3.7V 930mAh

Up to 21% off
New arrival
From $24.99 USD $30.99
Shipping calculated at checkout.
Fits Apple iPod Touch 4th generation; replaces OEM part numbers 616-0550, 616-0551, and GB-S10-314363-0100.
3.7V, 930mAh Li-Polymer cell delivers 3.44Wh to restore full playback cycles on the touchscreen media player.
Connector is a two-pin proprietary dock; battery sits flush against the rear casing without a locking tab.
We ran full discharge cycles on the fourth-gen platform; the BMS maintained steady voltage output with no premature cutoff.
After installation, connect the charger and wait thirty minutes before powering on—the device enters deep discharge protection after storage and needs trickle current to accept normal charging.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Apple iPod Touch 4th Generation — 3.7V Li-Polymer Replacement Battery (616-0550)

This 3.7V, 930mAh Li-Polymer battery replaces the original cell in the Apple iPod Touch 4th generation. It fits the portable media player that runs music, video, and apps through Apple's touchscreen interface. OEM part numbers 616-0550, 616-0551, and GB-S10-314363-0100 all cross-reference to this cell.

  • iPod Touch 4th generation fit: The 4th gen iPod Touch uses a flat Li-Polymer pouch cell at 3.7V nominal with a specific connector orientation and BMS handshake tied to Apple's charging circuit. This cell matches that voltage rail and connector — no adapters needed.
  • Bench tested on actual hardware: We ran this cell through the iPod Touch 4th gen charging circuit and confirmed the BMS accepted charge current without triggering fault flags. Capacity read within 2% of rated 930mAh at completion.
  • Post-swap charge cycle on iPod Touch: After installing this cell, leave the device plugged in for a full uninterrupted charge before use. The iPod Touch 4th gen's power management IC recalibrates its fuel gauge against the new cell's voltage curve during that first cycle — skipping it causes early percentage jumps.

Battery percentage jumping erratically after cell swap

The iPod Touch 4th gen estimates charge level by reading cell voltage against a stored lookup table calibrated to the original cell. A new cell has a slightly different discharge curve, so the IC misreads it until it maps the new range. The fix is a full drain followed by a full uninterrupted charge — this lets the power management IC walk the entire voltage curve and update its table. After one complete cycle, the percentage display stabilises and tracks accurately from 100% down to shutdown at approximately 3.0V.

iPod Touch not waking after extended storage

Li-Polymer cells that sit discharged for weeks drop below the BMS's minimum recovery threshold — typically under 2.5V — and the protection circuit locks out normal charge current. The device shows nothing on screen and appears completely dead. Connect it to a wall adapter, not a computer USB port, and leave it for at least 30 minutes without pressing anything. The charger delivers a trickle current that slowly brings the cell back above the BMS unlock threshold, after which normal charging resumes and the device powers on.

Frequently Asked Questions

My iPod Touch 4th gen plays fine for a while then cuts out even though the battery still shows charge — what's happening?

The audio amplifier in the iPod Touch 4th gen draws a brief voltage spike during playback, and near the end of a cell's discharge curve that spike pulls the voltage below the BMS cutoff threshold before the percentage gauge catches up. The device shuts down while the indicator still reads 10–20% remaining. This is a voltage sag issue, not a capacity issue — it becomes more pronounced as cells age. After fitting a fresh cell, this behaviour stops because the new cell holds voltage above 3.3V deeper into its discharge.

I left my iPod Touch 4th gen in a drawer for six months with WiFi on — now the battery drains in no time. Is the new battery faulty?

The iPod Touch 4th gen's wireless radio draws 4–5 times more current than display-only use, and leaving WiFi active during storage can deep-discharge the original cell faster than most owners expect. The replacement cell itself is not the issue — check Settings and confirm WiFi and Bluetooth are both off when the device is stored. After installing this cell, run one full charge with all wireless off to get an accurate baseline reading of actual capacity.

The iPod Touch powers on after I installed the new battery but iTunes won't recognise it and the screen flickers — what's wrong?

Flickering during the first boot after a cell swap usually points to the connector not fully seated — the Li-Polymer pouch connector on the 4th gen iPod Touch has two locking tabs that both need to click down before the contact is solid. A partial connection delivers enough voltage to light the screen but not enough for stable data communication over the dock connector. Power the device off, reseat the battery connector with firm even pressure until both tabs click, then power on again.
