Leapinglizardto 0 #1 August 5, 2008 How is it possible, that many of the modern comm. gadgets that I own. Take a charge twice as fast if I use them while charging as opposed to leaving them alone to charge. This makes absolutely NO sense. Shouldn't it be the other way around? Examples: *My laptop if left alone charges to full capacity in 1 & 1/2 - 2 hrs.If however I'm using it is as it's charging it fully recharges in 45 - 60 mins.*My PDA & WiFi card, same thing not using while charging, both charge to full capacity in 1 - 1 & 1/2 hrs. If I use them while charging, they reach full battery capacity in 45 - 60 mins.I don't get it! Isn't this completely backwards? It's pretty pathetic when you have to TELL people you're fucking cool Skymama «narrative»This thread will lock in 3..2..

Leapinglizardto 0 #3 August 6, 2008 Thanks smart-ass. seriously. That's completely fucktard backwards, & it annoys me because it doesn't make sense. But that is exactly how those three work. And I have nothing better to do but lay here and think about it.Well that or watch TV & there's nothing on the crappy cable channels I'm stuck with here. For another 3-4 days This is Bullshit.

billvon 2,998 #4 August 6, 2008 >Take a charge twice as fast if I use them while charging as >opposed to leaving them alone to charge. If you are using a regular charger (wall wart for example) then it's not true. Your device is lying to you; the state-of-charge indicator and the end-of-charge indication are inaccurate. If you are using a USB charger connected to a computer, and the computer is on, then the device has likely negotiated a high power (250ma) connection as opposed to the default (50ma) connection. Many devices cannot do that when they are off. Take this example: >*My laptop if left alone charges to full capacity in 1 & 1/2 - 2 hrs. >If however I'm using it is as it's charging it fully recharges in 45 - 60 mins. To go from zero charge to full charge in a lithium ion in 45 minutes you would have to seriously overstress the battery, to the degree that a catastrophic failure would become likely. The battery would certainly fail after very few cycles at such a charge rate (2-3C.) However, if your battery really isn't fully discharged, and charges at a normal rate, the charge termination algorithm can be easily fooled by the changing loads of your laptop (CD spinning up etc.) It may tell you it's fully charged when in fact it is only charged to 75%. This isn't all that bad; most of the charge gets replaced during the first hour of charging anyway, so as long as you have an hour you get most of the battery charged. Also note that most laptop battery charge systems can handle both laptop operation and a fairly high rate charge, so there's not much penalty for using the system while it's charging. For example I have a 32 watt charger for my laptop. Max charge rate is around 20 watts and the thing takes 16 watts in its usual mode (dim screen, no CD operation.)

Leapinglizardto 0 #6 August 6, 2008 Wow thanks billvon. I just learned a heck of a lot more than I expected to get in feedback. That was awesome thanks. Several things make a lot more sense from your explanations. For example the 'false' charge (state-of-charge & end-of-charge indication) as you refered to them. I never thought of this before, but now that you've said it. When I do use my PDA or WiFi card while charging, the 'full' charge never seems to last anywhere near as long as when I leave it to charge completely on its own. I'll end up needing to charge it several times in one day as oppossed to the charge lasting most of the day.It always seems to wear down MUCH faster.Also I never before thought about or paid much mind to, the dramatic difference in charging, between a wall wart vs USB. But again now that you explained it, thinking back you're absolutely right regarding that as well. My ipod and Zune same thing! And I'm sure everything else you explained.The only thing I ever really knew about these lithium/ion batteries, was the cycling process. Fully charge - fully drain, when brand new. But that may not be true either I'd take your word on it over the manuals. Very interesting & very cool thanks a brazillion bill. This has been annoying me for the longest time. You're awesome! I actually learned something new today! It's pretty pathetic when you have to TELL people you're fucking cool Skymama «narrative»This thread will lock in 3..2..
