Title: Mobile Battery - Nokia 5800
Post by: Zootoxin on May 26, 2009, 07:22:37 PM
Hi Guys,

Just received my new Nokia 5800 and it comes with a mAh Li-Ion battery.

Its a long long time a good in a far galaxy that I last had a brand new phone and back in those days we had to charge our batteries for 24 hours on the initial charge.

Is this still the case? I cant find anything in the destructions and things on the web are conflicting.

getting horror stories of undercharge but also over charge!!

Any one got this phone or simular?

how long did you charge for? is it ok?

My friend has one, and was told to charge before use. Although it comes with a little amount of charge already. I don't think you will cause any harm either way to be honest, items of today are pretty robust.

As you say, it is a lithium ion battery (http://en.wikipedia.org/wiki/Lithium_ion_battery#Advantages_and_disadvantages) and general rules for such applies. Basically, the battery does not care how you charge it so you do not need to fully charge before use - that is a leftover from nickel cadmium batteries of the past. The do however lose power with age, regardless of use. Also, when they appear to have recharging issues it often comes from a need to recalibrate it. This can be done with full dis- and recharge. Google lithium-ion with respect to mobile phones and you find tons of guides, e.g. this (http://www.batteryuniversity.com/parttwo-34.htm)

Edit: good point T-Bag. My laptop li-ion battery recommends 90-96%

Rules for charging. Don't charge when it is above 80%, don't let it go below 10%. Running them dead damages them.
Keeping them in hot places shortens their life span, so charge it out of any case and out of direct sunlight.
Lithium batteries are more forgiving of not draining them full and love a routine. Charge to full drain to 10-15% and repeat will see it last years.

When it comes charged in the box it's fine to use until the battery warning comes on the phone.
