Battery (or software) problem

[steli89]

Hi!

I've bought a HTC Desire two months ago and I started having the following problem:

My phone always dies before the battery reaches 10%, usually between 15% and 10%.
When the phone is charged after dying, it starts from 0% and it usually goes from 88-90% to 100% instantly, the outer led turning to green.
I thought ok, this may be a battery bug, until this evening when I charged my phone from 0 to 15%, had to leave and it wend dead again at 12%.

Has anybody had this issue before?

I use the Quick Battery widget for displaying this (I don't think that causes any problems).

Thank you!

How long does your battery last and how much use does it get? If the phone is new, I'd be taking it back, if its second hand, I'd be getting a new battery.

The phone is second hand.
The battery lasts between 1 and 1.5 days with moderate use (around 30 min of calls, some browsing via wi-fi, some radio etc). The duration seems to be ok, the issue in the original post bothers me.

If the battery lasts that long I'm guessing there is nothing wrong with it, and would now turn my attention to that widget. Uninstall it, install another and see if it does the same thing. You can always re-install your widget later once you know the problem.

I don't think it's the widget, as that simply reports what the phone thinks is the battery charge more accurately than the status bar icon.
I'd seriously be looking at calibrating your battery, the symptoms suggest that the phone's calibration has drifted at both ends so that it cannot accurately report the correct state of charge.

I did this last year, when my battery was starting to complain in the evening, and got quite an improvement.

Thanks for the advice! I will try that as soon as possible.
