Something weird has happened with my batter charge. Ever since I got the n900 I have had to charge it every day. Usually it lasts 24 hours, sometimes only 8-10 hours, and if I am using it near a plug, I tend to leave it connected to the charger. I let it discharge every week or two, then leave it to charge fully. Yesterday morning it was due to be plugged in - but was still nearly fully charged. This morning, still on green. This evening, it is just about down to the red. That's the best part of three days. I haven't done anything out of the ordinary - I haven't downloaded anything I can think of. Weird. This is what I would have hoped for with a battery - but it has never gone this long before.
