How do I change the battery of the device?

Yes, unfortunately the battery in this device is soldered in place. To replace the battery gently tug on the old batteries soldered connection to break the wires free, making sure not to pull the wires out of the motherboard. Once here make sure the tips of your wires, no more than half a centimeter, are clean without fray or corrosion. Now, you must solder the new battery in place with a soldering gun. Route the wires in the same fashion as the original battery. Once all connections are complete, sealed, and cooled down, it is time to but the device back together. Now try restarting your device, and enjoy the extended battery life!
