Seems like the DroidX takes a long time to charge

    My DroidX is my first Android and I just came from using Blackberry for several years. With my last Blackberry (Tour) it only took about 60 minutes to go from 0% to 100%, though I never took it that low and usually got a full charge in about 45 minutes.

    The DroidX seems like it takes at least two hours, if not more, to get a full charge from near zero to 100%. This is when using the supplied wall charger.

    At work I use a microUSB cable to charge my phone since I don't have a wall charger there. With the screen locked on (using the dock mode as a clock, though I don't actually have the dock itself) it did not appear to charge one bit after about an hour of being plugged in. The percentage never changed. I was kind of surprised that the phone is using all 500mA that the USB port is supplying just to run the screen. This means I can't have the screen on and expect to increase charge at the same time. Kind of sucks because I like looking at it.

    Has anyone found a true rapid wall charger for cheap on Amazon or eBay? I've had bad luck before with other crappy wall chargers that put out less current than a USB cable, so if anyone has confirmed a good one, please let me know. It's also kind of lame that the supplied charger has such a short cable (I realize that's because it's a USB cable) but I'd like one with a longer cord. I just ordered two car chargers that people recommended on this forum so I've got that covered.

    Any help would be appreciated.

    USB won't charge as fast as the wall. You should try to always charge via the WALL charger that came with your phone. If the cord is short, don't get a longer USB cable...get an extension cord.

    I think you missed the point of what I was saying. I'm well aware that the wall charger charges faster than the USB, but even the wall charger seems to take longer than I would like. Charging with the USB is painfully slow or non-existent if you're using the phone for anything.

    I was focused on this part.

    And wanted to mention the extension cord thing in case u had a long USB cable.

    extension cord is definitely great i have a 10 foot one

    but i thought taking an hour or two to charge was really fast cause with all my other "dump" phone it would take all night to charge them

    i think its just different phones and batteries take different times to charge two hours is still pretty fast

    A rapid charger would be good. Does that shorten the life of the battery though?

    most computers USB ports can only output 500MA (some do more, check MB specs

    almost all wall chargers output 1000MA.


    FWIW, i haven't experienced any abnormal behavior with charging the phone. perhaps your battery is bad, or the charging circuitry is misbehaving.

    the droidX, when connected to a 1A port will charge from 0% in 1.5 hours. (1540MAH battery)
    the BB tour when connected to a 1A port will charge from 0% in 1.4 hours. (1400MAH battery)

    (assuming no load on the battery)

    no, the Lithium batteries can be safely charged with no impact on longevity at 1C (1,540MAH in this case) charging at 1.1-2C tends to negatively impact battery life. and cant be done on a phone.

    So either have a bad battery or using a long USB cable or your charger/cable is damaged or phone is ganked or you're exaggerating. Sorry, not trying to be a jerk...just helpful and maybe funny.

    Let's face the facts here. The phone should charge off the USB port of his computer as all of ours do.

    I'm betting the phone gets darn hot when he's charging it on the USB port doesn't it?

    Download the free app called CPU Usage and you'll find your culprit.

    For the record, it does charge through the USB, just slowly as expected. If I'm using the phone for anything while charging on the USB, it effectively doesn't charge at all as out appears the 500 mA supplied from the port is totally used by the phone and display.

    Again, I'm comparing this to my BB Tour charging in the cradle powered from a wall charger. Never took more than an hour to charge no matter how low the battery was.

    But don't get me wrong, this isn't a rant about how I regret switching to Android. I love this phone and couldn't imagine going back at this point. BB feels so ancient compared to this. I just need to change my charging habits and buy more chargers.

    Just wondering if anyone else thought their Droid X charged slow.

    NOTE:
    While charging a phone ALWAYS have it turned off for a faster charge
    Also Before plugging you phone into a home charger turn the phone off and then plug it in, if needed on turn it on after you plug it in, this will prevent damaging your battery, over heating your phone, and a faster charge

    The Droid and X will turn on when you charge them. Its by design....

    I don't know about the X, but my Droid cannot be turned off while charging. If it's charging it's on.

    not total b.s.
    i'll explain why...power grids in the united states notoriously put out unclean power. most people don't plug their cell phones into a ups battery backup/clean power converter like they do computers/tv's/sound systems/etc. although not probable it is possible to damage or ruin your cell phone by just plugging it into a wall outlet.

    that being said, i don't follow my own advice. it's too much of a hassle.

    as far as the droid x charging slow, i agree. my x takes forever to charge.
    -as far as turning the phone off while its charging...why would you want to turn this phone OFF? madness...

    I'm sorry but this statement is incorrect. The AC to DC conversion taking place in the wall charger eliminates all possibility of destroying your phone from "unclean power". You could destroy your wall charger, but US electrical standards dictate that all AC to USB chargers can handle an input current from 110v to 220v and will output 5v at 50hz or 60hz depending on the input current. Short of your line being hit by lightning you're perfectly safe.... and if your feed line was hit by lightning and wasn't properly grounded you have far more to worry about then a $500 cell phone.

    I think the charger has a fuse in it, no?

    I've owned cell phones since the late 90s and I've NEVER turned it off before plugging it in and I've NEVER had a phone or battery break down.

    I file this under the "battery pull" mythos. Somewhere along the line, some crappy phone (a blackberry) needed it's battery pulled. Now everyone goes around pulling the battery out of the droid to fix problems. Just reboot the frickin' thing!

    ps: I do agree that charging with your phone off will make the phone charge faster but:
    1) how will you know when it's done charging?
    2) the droid turns on when you plug it in so the point is moot

    ...you may be right, but it's not how it is in los angeles. we get power spikes and brownouts all the time because of the heavy usage in the grid.

    Cool, well you may be right too. I've just never heard of this and never done it. I'm trying to save people unnecessary headache, if possible.

    Basic electrical engineering has to question what's going on here. The battery that comes with the phone is a 1570mA battery. We can assume your USB output is 500mA as expected.

    If you aren't seeing significant charge while the phone is on then we can assume the phone is burning 400mA + This would translate into a battery life of around 3-4 hours. This is without putting any additional load on the phone by making a phone call, etc.

    Considering I can get 20 hours easy out of my battery this means I have a average current draw of about 75mA. EVERYONE gets about 10 hours of charge out of their phone and that would mean their phones have an average current draw of 150mA. What in the world do you have running?

    I don't doubt you're telling the truth, I just have to wonder what widgets and apps you got going that would pull that much current. Your CPU probably never clocks down.
