Proper wy to charge the n900?
 
Hi i was wondering whats the proper way to charge the n900 right out of the box, to extend the battery life. I was wondering right when u take it out of the box put the battery in do u turn on the device and charge it? Or leave it off and charge it until its full? Some people say right when u pop in the battery use the device until all the battery drain then charge it.

Simple Guidelines

Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.

Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)

Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.

If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

In particular:

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

My baby is currently on it's first charge. How reliable is the info posted above? I'll be leaving it plugged in all night, but want to switch it on and set it up and activate the SIM, etc tonight. But don't want to hurt my baby in any way shape or form! lol! I know I'm being a little OCD about this, but it someone could clarify for me I'd be very grateful.

Also wondering.

Tomorrow I will be receiving my phone and obviously I'll be tempted to power it on right away. But if charging it first, WITHOUT powering it on is healthier, then I'll probably do that.
Where's the experts?

It's a neat idea, but the piece that goes on the back of the device is actually pretty thick, all things considered. Now, if they had custom battery covers like say the Palm Pre's induction charger, then I'd get one.

Arg the wait is killing me!! lol!! I did read in the manual that if you have a lot of Apps & widget running that it could drain faster than it can charge (not sure if it meant in general or from a USB port - hopefully it means a USB port, otherwise that's ridiculous!)

I;m only planning on setting it up, get contacts on and testing out the web browser, so think I'll switch it on (but leave it plugged in) in 5-10mins. It will have been plugged in for 1 hour by then!

PS. The notification light doesn;t simply flash on and off, it fades in and out...it's like a little heart beat :o)
