O2 pda long enough presence in the world. o2 provide satisfactory service for a pda phone. o2 now providing services for replacement batteries. A fairly chunky replacement of the original o2 battery provides large capacity and worth the purchase if you can live with a little increase in size.
Comes with new back cover because the battery is thicker than the original and the protective certain cases may not fit anymore. Rubber case I was still fit even though some stand out in places.
Battery life has taken a dramatic improvement though, where I should be used for the cost of the phone every night I can now get through about 4 days without charging on the use of moderate, occasional phonecall and a few sms a day.
This is a battery that would allow heavy phone / pda / video / radio use and still get all day.
I highly recommend it if you can live with the increased size and the benefits using this pda longer.
