Battery Charge Time
Ok - Some background -
This past weekend I flashed DL30, and I've tried the battery clear stats in clockwork. So I've been draining my battery throughout the day and then charging completely at night. Well - last night I decided to pay attention to the charging time, so I stayed awake for the end of it. Took right at 3 full hours 8:10 - 11:10 for a complete charge from my stock charger plugged into the wall. Is this normal at all? Seems super long! Any suggestions.
Oh - I wasn't on it at all why this happened either and nothing was running that I know of. I maybe sent 3 gvoice messages and received maybe 2 texts. I run Launcher pro. Thanks in advance.

Sounds about right to me. Mine takes even longer if it's plugged into my car or something, but that's also because the car chargers are of a lower voltage.
Welp - got 2 replies saying the same thing - one from a moderator with the same phone, so I guess it's about right. Just don't get how much buddy's original Droid only took about an hour and a half to charge with the same size battery (and while he was on it)?

It really just depends on the phones design as well. Motorola phones have always been known to charge quick, and that's because Motorola designs most of their phones to accept a higher voltage than others. The higher the voltage, the faster it charges.

Been there, measured that, roughly.
The power system on the Fascinate pulls about 650ma @ 5 volts from the power source. (About 350ma on a PC USB port).
You can assume that the Fascinate system is pulled 50 to 100ma while suspended.
So that leaves you roughly 575ma @ 5 volts, or roughly 2800milli-watts, for charging.
The Fascinate battery is roughly a 6000mw/hour battery. So a dead battery will take a bit over 2 hours to fully charge. Add in the inefficiency of the circuits, and the facts that the charge gets tapered off when it is near full, and you are going to get very close to 3 hours. )And a lot longer on a PC USB port.)
BTW, that battery will last longer if you keep it closer to full.

This phone uses LiIon batteries, and should be kept charged. Running them dead simple accelerates plate wear and shortens their life. When you have a chance to charge it, charge it, and avoid deep discharges.
The exceptions are, avoid charging it when it is real hot. LiIon hates heat. And very occasionally deep discharging it may recalibrate the battery gauge.
Basically, keep it charged and avoid high temperature, and it will last longer and hold a charge longer.

I have a question regarding battery charging. it happened with dl30 and now with eb01. the battery meter does the charging animation until it hits 90% and then stops the animation, looking as if it is full and not plugged in but still charges to 100% and pops the battery full popup when its done. its strange...i have tried resetting the battery stats and going through that and i am stumped. any ideas?
