At least it seems the DHD was a 'blip' in the system, it was worrying that a phone that struggles to make it through a single day made it through R&D imo.
To be fair, I've found my DHD actually lasts longer than my Hero and definitely longer than my gf's Desire. She has to charger hers up every night whereas I can get two days use out of mine and I use it more than her!
I'd still like to be able to use it for a few days though without having to charge it.. Apart from that I love it!
