I've had a read through the other threads related to this issue but I haven't come across anything remotely as extreme as what's happening with my N900.

Today for example, at 2pm my phone was fully charged with green light. At 8pm my phone was dead.

In this time my only phone usage was sending one text message, receiving one 10 minute call and accessing about 6 web pages through the maemo browser.

I'm pulling my hair out at this point.

I have the current firmware installed, no apps that particularly drain power. No power kernel installed and it's not overclocked.

I would be most grateful if anyone could share some advice.
