Good Shave But Terrible Battery LIfe

I've only had this shaver for a couple weeks. My beard is getting used to it and it's giving a decent shave. However, the battery only last for two, maybe three shaves. I charged it for 24 hours upon receipt; so, I did my part. The sideburn trimmer extends nicely and at a useable angle. I bought this shaver fairly cheaply on ebay and that's the only consolation. It's much more quiet than my previous Braun. The Braun was an ok shaver but a cheap plastic part broke and the trimmer would not retract. I would not pay retail for this shaver because of the battery life. On the other hand, just plug it back in and it'll be ready in a couple hours.
