Amusing battery glitch - anyone else?

[tiggerntatie]

I fully charged my Centura, popped it in to my pocket before I left for work, then discovered the battery dead about 11 hours later (which is unusual). I didn't use the phone at all while I was at work. When I looked at the battery level history graph it showed the level dropping instantaneously from a near-full charge to zero.

Has anyone else had this problem?

It's most likely a defective battery.

If it dropped to 0, then came back with a little less charge when you turned the phone on, it's probably has one cell that's growing a dendrite - a little crystal that eventually punches through the insulation between the positive and negative sides of the cell, shorting it, causing the phone to turn off and burning the dendrite out. Until next time.

If the whole battery went dead and won't charge, it's unusual, but it's a failure of the safety system in the battery.

Either condition should be covered by the warranty, but good luck - batteries are considered consumables, and aren't covered by the people working in the places you bring the phone for warranty coverage. Even though either case is a manufacturing defect, which the warranty specifically states it covers.

It seems to be recharging quite happily now. It seems impossible to me that the charge could drop to zero like that without producing a large amount of heat. I just don't get it.. I tried to include the screenshot of the battery graph to help explain, but as a new member I can't post pics.
