Hello, I know there are some other posts on this topic, but I wanted this to be separate as I'm not sure if it's hardware, software or charger fault related.

To keep it short - After I updated from 1.2 to 1.3 my wall charger didn't load my n900 battery, meanwhile usb charger performed as usual. So I started to think that there is some app or something that uses too much power - that wall charger cannot handle it. So I reflashed my device to 1.3 and installed battery graph to see what's wrong.



URL to Picture

At the begining it charged from wall charger (see 19.12.2010 11:30 to 12:00) and power consumption was quite low (10% drop in approximately 10 h), but then in 2012.2010 some background app or something kicked in power consumption doubled. and wall charger wasn't able to charge anything overnight. Then USB charging worked well but still some cpu usage can be observed (I didn't use my device almost at all) and now in 22.12.2010 power consumption returned to previous level.

Here is printout from charging monitor:

So my question are:
Can someone suggest some other tests I could do to track down this problem?
Does anyone knows how to fix this issue?

Meanwhile I'm thinking to reflash back to 1.2 (not shure if it will help)
