Mysterious battery behaviour

[astryger]

I had about two hours left on my XDAII battery when I switched the device off. When I then tried to switch in on, probably two or three hours later, it would not switch on. The green light was blinking as it normally does when the phone is on. I plugged in the cable to charge it, but the light did not change into a steady green (or is it yellow?) as it does when you're charging. I didn't want to hard reset it because I would lose some data, so I took out the SIM card and put it back in, as this normally soft resets the device. Instead however, it hard reset it, and I found the main battery to be empty. This still shouldn't have hard reset it, should it, since my back-up battery was full?

This has happened twice now. I'm starting to suspect that something is draining the battery even when the screen is switched off. Has anyone else experienced the same?

This may be obvious and you already know but it's worth considering.

When you switch off are you sure that you are turning the XDA II off or are you just turning off the backlight?

A quick press of the off button turns off. An extended press just switches off the backlight and the XDA stays on, draining the battery.

I've made this mistake too, especially in low light conditions. Hope this has helped.

Yes, that must be it! I had no idea that the off-button behaves like this! I don't think it did on the XDAI. Thanks a lot for this information, I will now be very careful with how I press the button, and check the screen in good light just to be sure.
