My phone has been off charge for 17 minutes. Current battery level, 88%. I've had my Desire for about a month now, so this isn't a case of the battery having to be charged a few times before getting the best out of it. I genuinely believe I have a fault with my battery, Bit of background information, both wifi and mobile internet are off, I'm not running any apps in the background such as a music player or internet stream. No apps have regular sync updates, they're set to update every 3 hours and even then this is only on one or two apps. The majority do not auto sync, just manual. Is there anything I can do? Surely for a phone to have drained 12% battery life in 17 minutes whilst not in use is extremely excessive, even for Android!?
