I did this, and it works great for me!:
Train the battery by fully charging it, and draining the battery until it shuts off.
1. With the device turned off, fully charge the battery until the LED no longer flashes, and remains on.
2. Let the battery charge for an additional TWO hours.
3. Repeat the process again (perform twice in a row) and you should experience improved battery life.
