Any Cell Phone Gurus?

<div class="IPBDescription">battery question...</div> Have a t-mobile sidekick, it has a lithium ion battery. In the manual it recommends always charging the battery fully. Now, to my knowledge, the only reason it would recommend this is because that is a relic piece of advice left over from older batteries which would develop a "memory" if certain cells within the battery were not fully charged, in which case they would later remain unused. I seem to recall having read somewhere that Li ion batteries no longer suffered from this problem, but I could be mistaken. Any ideas guys? <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'><!--endemo-->

    Always let your battery charge to the full. Not only is it easy but it's convenient because you never know when the power will go out...in which case your cell phone is an expensive block.

    Hehe, I'm fully aware of the benefits of having a fully charged battery. My t-mobile battery can last at least 19 hours without charging that I've noticed so far. My question concerns the hazards of not fully charging the battery, ie removing it from the charger before the little 'charging' animation stops occuring.

    You can charge the lithium-ion batteries anywhere at any time (even when only partially charged or whatever).

    The ones you can not charge in such a way are the nickel-cadmium. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    RPG - is totally correct. I work for Cingular Wireless and the actual lifetime expectancy for any Li-Ion Batt. is about 1 1/2 years before you have to buy another one regardless of how you charge it.

    There is a new battery out called a lithium Polymer. Much lighter and can hold a charge for about 33 percent longer than Li-Ion as well. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo--> <!--emo&::nerdy::--><img src='http://www.unknownworlds.com/forums/html/emoticons/nerd.gif' border='0' style='vertical-align:middle' alt='nerd.gif'><!--endemo-->

    Edit: Also - Ni-MH batteries develop a memory too. (Nickle Metal Hydride)

    after a good overnight charge my nokia 3310 can last 2 and a half weeks with no charge on standby. It is a non standard battery though. And i get about 20 hours talk time after a full charge.

    meh battery = pwn
