I bought a HTC Desire on a week ago and love it. Only problem is tat the battery is dire. I found it lasts for about 4 hours then it's dead. I am not running any apps or Wi-Fi, GPS, syncing etc. I initialy put id down to me playing with the phone constantly for the 1st couple of days. However by the fith day the battery was still dying in 5 hours or sooner. I took the phone back suspecting a faulty handset or battery. Got a new phone and battery. Still have the same very poor 4 or 5 hour battery life. I have loaded 'Battery Graph' app and you can see there is almost a straight line going down losing 20% of power every hour!!!! This is even overnight when it's doing absolutely nothing. I have also loaded Advanced Task Killer and go tthat shutting down any errant apps every 30mins. Still no improvement in battery life. Any ideas what may be causing this? Neither of the batteries I have had have hologram stickers on them like my old Nokia did. Should the official batteries have hologram stickers? Any help much appreciated.
