Batteries and Mobile Phones

I've bought a new mobile phone and I was wondering whether the battery was a Lithium ion (because if it's not, I should take care with any possible "memory" effect). I've looked at the battery and it didn't provide me answers. I haven't tried talking to it yet, but I don't think it's going to talk back.
It's a Nokia 1600 :) |

have you looked on the Nokia site?
I'd be surprised if they even made a battery thats not Li. |

Maybe it's one of those common features that they don't even bother mentioning anymore :p
I'm asking this because I couldn't even have a proper conversation with my old mobile phone, after a couple of years, because of the memory effect. I was told that the reason why this happened is because I used to wait until the battery was completely empty in order to recharge it.
So, I can recharge it anytime and not worry about the memory effect, right? |

| I highly doubt that kind of batteries are even being made these days. Time to get out from the nineties :p |

A lot of current batteries rely heavily on this memory effect even today, it's the reason why cell phones hold a charge as long as they do.
You're supposed to charge the battery fully and let it drain to dead or near dead all the time. Doing so will allow the battery to stay charged longer and extend the life of the battery.
If you only let the battery drain to 50%, then eventually the battery is going to act dead even though in theory it should contain 50% charge. |

| Standard 1600 battery is a 900mAh Li-Ion. |

I don't know about quoting wikipedia on a subject like this ( which always causes controversies ) but you are wrong
http://en.wikipedia.org/wiki/Li-Ion...on_battery_life
but here goes:
| quote: | Guidelines for prolonging Li-ion battery life
- * Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.[3]
- * Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.
- * Lithium-ion batteries should never be depleted to empty (0%).
