After PR1.1 install my battery was fine, i.e. no problem going through the night with plenty of charge remaining... However this past week I noticed things go down hill rapidly and have been having to give the device a top up charge in the morning just to make it to work with some juice...

The only real difference this past week had been the addition of the conversations widget to one of my desktops... So yesterday after reading through the latest postings on this thread I uninstalled firefox, the mozilla runtime and I removed the conversations widget from my desktop...

My N900 was plugged into my computer last night via USB and the battery indicator was showing full (green charge light), this morning I am happy to say that it is still showing full! Thats with it being on 3G and using data off on and throughout the night as it updates Mfe and email...

I cannot confirm if it was firefox or the conversations widget but firefox was installed prior to PR1.1, the only change recently was the conversations widget and it was around this time that I noticed a massive drop off in battery life. I removed both just to be sure however!
