Phone Saver
I was considering replacing my HTC Desire Z as it's now almost three years old, was getting a bit slow, the internal memory was constantly filling up and the battery was lasting only a few hours. I read about and decided to try the Mugen 1800mAh replacement battery, reset my phone to factory settings and it's as good as new. I can now listen to music all day without running out of juice and the phone has a new lease of life. So spending £29 has saved me about £400; a very good buy indeed.

The battery the phone should have come with...
enough said, was lucky to get 20hrs out of original battery. Now getting with normal use 40+ hours. No I'm not a heavy user, but its a vast improvement for only 350mAh extra!!!
