Well people....i was just about to post a thread about this exact cradle....i purchased one about 2 weeks ago (link below) and so far am not happy....i think its completely killed my battery!!!
Warning: DONT keep your phone sitting in it all day at work especially if its fully charged....it seems it keeps charging and hence overcharges your battery and starts killing it...
i left work at 5pm yesterday with it sitting in there all day...fully charged...left it in my pocket un touched while have a few drinks at the pub and bang by 9-10pm (under 5 hours) it was DEAD....
Also (which might even be the cause of this) today i thought...."well i still want to use the cradle so ill unplug the charger AC mains cable from the back and just use it to sync"....The bloody thing was still charging!!! looks like it uses USB power and AC power to charge....surely this cant be good!!
Anyway just my thoughts/review, hope it helps.
