I went online to purchase a extended battery life for my Palm Pre 2 which the entire phone it has a terrible battery life. The included battery inside the Palm Pre 2 is just way too small(capacity) and despite managing its battery life with minimum ways to not browse the web(too much), and many other things the battery doesn't hold up. Anyways, I purchased the Mugen battery pack and it was delivered to today only to find out that it doesn't fit my phone. I compared the battery side by side of my device, while being the same height it turns out not so much on the width(thickness). Did I purchased the wrong battery from Mugen 1400 mAh or Mugen is lying when saying that it fits the Palm Pre devices ?
