Re: Battery question

Turn off wifi when you're not using it. When it's at idle (it never really is because it runs stuff in the background), it hogs a lot of electricity.

No because, the first 70-80% charge will go fast (full power, 1300mA) then the voltage potential will be closer which means it will charge with less power until it reaches 100%, the last 10% it will charge with max 200mA

For more info go to my battery thread, i have a discharge & charge graph in there somewhere, i can charge my N900 in 2 hours, there is just one little difference, i have a 3000mAh battery, and i use an external charger that i set at 2500mA when charging my N900

Link to page where i posted my graph

Mine too. I rarely use the USB port to charge. Presumably the slower charge means it is charging at a lower amperage? Do you notice any appreciable difference in the length of charge from a USB port compared to the electric charger? I can't say I have, when I have charged that way.

Mine is still holding a charge for between 1.5 & 2.5 days. I did take the advice and remove the three monitoring widgets I was running. That only leaves a couple (including weather) left that I like to keep on.

I did trash my easy debian install a month or so back, and haven't got round to re-installing it. I wonder how much juice running easy debian takes up? I only had it for occasional Iceweasel and OO Write/Calc use - and haven't really missed it much. I think having a charge last 2 rather than 1 day would be a good enough reason to not bother with it. I wish there was something like AbiWord on maemo, like the recent implementation of Gnumeric...

2.5 days? That sound really nice to have. I only have Weather and APNews widgets, and do use for phone (~less than an hour/day average). Occassionally I tinker with some apps. I guess combination of these cause my battery life to drain 1.5 - 2days max (fingers crossed).

Re: Battery question

I have a JustMobile GumPro charger, it puts out 1000mA USB, so my N900 charges usually within an hour. It has a 4400mAh battery, so I can charge my N900 about 3 times before the GumPro needs juice.

Yes, I have 2 original Nokia batteries. I'm rotating them on weekly basis since I don't have an external battery charger (charge using the N900). It's a bit of hassle, but I had to get the extra battery since I was going for a business trip. Now it's like having insurance - I have peace of mind because I have a spare battery in my bag with me.
