With my standard battery I would take it off charge and with moderate use (2 or 3 calls and check emails every hour by the time I got home after 8 hours battery was on about 20-25% so had to charge every night. Put in the new battery about 10am Yesterday, again low/moderate use when I went to bed at 11pm it was on 30%. By the time I got up this morning it was flat. Dont know what is draining the power.....
Early indication is that the Momax battery definately lasts a lot longer. Today I worked an 8 hour day, had music on for 3to4 hours checked my emails every hour and made 3 calls, received 2 calls. When I got home , phone was still on 68%. With the standard HTC battery it would have been around 30-40%. It will be interesting to see if this continues.
Been using the Momax battery now for a week, definately better than the original. I have had at least 50% left every day after medium to heavy use inc music,web.email and sat nav. I would definately buy from them again if I needed another battery.
