thanks it does look llike what i am going tobe looking at changing...or i might just get a new phone when the HTC s730 arrives.
The lil battery isn't for date/time backup
AFAIK it keeps your phone settings and for example alarm clock settings but NOT the regular date/time you are expecting.
The newer Tornado's have the same backup battery there, but also loose time and date after the main battery is removed.
So it looks like you may need to shop with another manufacturer than HTC because they all have this problem (at least 2 PDA's I have do it too)
Apart from that, the battery 'clip' is spot welded to the top of the battery so you can't even (easily) replace it anyway.
Just so you know.
