Re: Boot in 5 seconds
 

Booting the tablet wastes as much battery as several days of standby. You gain nothing by switching off the tablet.

Listen to qole, he got it exactly right. So did pycage. There's no reason to ever turn the N8x0 off, unless you're putting it in storage or something. In that case you would be better off if you charged the battery half way, remove the battery from the tablet, wrap it in plastic and put in in a fridge.

Re: Boot in 5 seconds
 

I agree with everything but the 'fridge part. It is false that putting batteries in the 'fridge is good for them.

Re: Boot in 5 seconds
 

"Batteries" is a bit non-specific. Alkalines, sure, but lithium-ions, no. Li-ion degrades faster at higher temperatures, keeping them cool (and at around 40%) slows the rate of degredation.

I got that information from what's usually described as a very reliable source: http://batteryuniversity.com/parttwo-34.htm

Okay. I don't want to start a feud, especially since Ryan has entered, but....

The batteries in the Nokia N800 / N810 have a tiny circuit board with electronic parts mounted on it. What is bad is the humidity in the refrigerator is at 100%. This is bad for any electronic circuit.

I know the batteryuniversity.com has that chart but it is referring to individual lithium cells (or an array) but not the circuit boards that smart batteries have in them.

I advise against anyone putting a laptop, cellphone, Nokia N8x0 or any smart Lithium Ion battery pack in a refrigerator or a freezer. The humidity will attack the circuit board in the pack.

Duracell's website advises against placing alkaline cells in the 'fridge as well. It really doesn't do much, and the humidity isn't good for them either, even though there isn't circuitry involved. Common alkaline batteries have a shelf life at room temperature of between 5 to 7 years. No refrigeration necessary.

http://www.duracell.com/oem/primary/...kshelflife.asp

The data at the link above (Duracell) recommends Alkaline cells be stored between 50 F and 77 F, with no more than 65% Relative Humidity. A refrigerator exceeds the humidity spec. and also is colder than 50 F. Bottom line is, don't bother putting any of your batteries in a cold, damp environment like a 'fridge. Just keep your batteries at or somewhat below room temperature, in low humidity.

Lithium ion long term storage starting at 40-50% charge is good advise.

As far as booting the N8x0 quicker, just don't turn it off, and boot time isn't factor. I leave mine powered up all the time. I lock the screen and keys before I go out of the house with it.

Re: Boot in 5 seconds
 

How about changing batteries? I change batteries about once a day. Any suggestions on how to change batteries without rebooting?

Re: Boot in 5 seconds
 

Yeah, don't freeze the batteries, that won't do any good. The question about the humidity is a good one, that was why I added the 'wrap it in plastic' part though.. (make sure it's airtight) :) It's probably safe for everyone to just store the batteries (at, say, 40%) in the basement or any cool area in the house.

@geneven: There's no way I can possibly think of that would let you switch the battery without rebooting (or more correctly, shutting it down before removing the battery), as the tablets can't run with only power connected. It needs the battery in to work.

Re: Boot in 5 seconds
 

I have a spare battery too, but I wait until my tablet's battery runs out before swapping. Mostly I use an external battery pack to avoid having to turn it off at all.

Re: Boot in 5 seconds
 

I read that advice before, on Thinkwiki. Why is 40% good for the batteries?
