Does the Droid 3 drain faster than it can charge?

I have a Motorola Droid (1) and it has just about given up the ghost, so I am forced to replace it, and am considering the Droid 3 or Motorola Droid x2

My biggest complaint of the Droid is on long (12-hour) motorcycle trips I often found that, even when plugged in, playing Music and running navigation (screen and GPS always on) it would drain the battery faster than it could charge it and run out of juice and shut off in the middle of a trip.

Does the Droid 3 suffer from this issue?


Bonus question, how well does the droid 3 handle high heat?

What happened to your Droid1 ? My son still uses his and he doesn't want to upgrade.

I would get the Droid3. In fact, I got the X2 first but returned it, paid the restocking fee, and got a Droid3 instead. I like that it is a bit smaller and that it has a Really Useful keyboard. Since you have a Droid1, you are not used to having a Really Useful keyboard, but trust me you will like the Droid3 keyboard.

It depends on the power source.

I have had this happen while charging via a cheap AC-to-USB adapter plugged into a Walmart 12Volt car invertor, and into a laptop (Toshiba) USB2.0 port. I have also had it happen with a direct cigarette to USB adapter, non-Motorola. There is a reason for this though. Here is the relevant USB2.0 spec:

" A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0"

If you look at the Motorola Media Dock power supply Verizon sells for the Droid3, etc, you see it supplies 750mA, and it barely manages to keep up with the Droid3's power needs. I use an Apple white cube power supply to USB and it supplies 1 Amp (1000mA) and it does NOT ever get behind while streaming Pandora or Google Music through 3G to BluTooth headphones while navigating down the road.

If you are motorcycling and plug your Droid3 into a USB port on your bike, just be aware that no USB2 port is required by spec to supply more than 1/2Amp at 5 volts altogether. If you have a 12-volt invertor and an adequate 12V to USB adapter, you'll be fine. Some USB ports might well be able to supply more than the minimum 1/2Amp spec, its not required that they don't, but most or all are made in China these days and they do not necessarily exceed spec...or even meet it...

Good luck and go with the Droid3 is my advice.

My Droid 1 is unresponsive and very slow when even slightly warm, and unusable when hot, even after a full wipe. I suspect the thermal compound on the cpu is worn out or its the cpu itself. Icons on desktop take a minute to display, rotating screen crashes current app, apps lod 50% of the time or crash.

Thanks for the Amp tips, the inverter trick is doable. On the bike, minimizing cords is a priority, but not a higher priority than navigation that keeps forcing me to take exits and take my gloves off to restart.

Seems silly I need to convert 12vDC to 110vAC to 5vDC, but if thats what it takes to get it right... :rolleyes:

Just like everyone else has stated, whenever I use my D3 with the car dock, I have GPS, Navigation and Music going at the same time and the phone never ends up with less battery than when I put it in.

Thanks

Check you charger spec for the output amps. I have noticed a lot of 3rd party are very low output, I went crazy once trying to figure out why my D3 was not charging and found out I was using my head phone charge cable which only puts out 150mA and the Media Dock puts out 750mA.
Good Luck....

I have been looking at this. Seems the max mA Motorola branded charging cable is 850mA, I bought one of thease and whenever I use it my touch screen becomes glitchy (clicking all over, registering multiple clicks for one finger) Hopefully the D3 is better at handling this amount of input miliAmps.

Sounds like you are right, that the phone hardware is failing. Might be bad memory. Make sure since its a Droid1 that the SD chip is connecting right, in a clean socket and that its a good SD chip...you might also want to do a Factory Reset and ROM it with Cyanogenmod, before you toss it. Feel free to toss it my way if you decide its just not working reliably anymore :)

Well, maybe not. If you have a cigarette lighter 12V outlet on your bike, you can get one of the Motorola car charging adapters. It will take the 12V down to a fairly stable 5V all in one step and includes all the cording you need, and it will for sure put out adequate amps to charge your phone, assuming you are not having 12V supply issues with the bike electrical system. I've got one, be sure its a real Motorola one. Mine glows blue with an M in a circle when its working.

That's thinking about it wrong. The rated mAmps is how much current draw from the phone the adapter can handle without dropping the voltage (+5V) or melting down. You cannot plug you phone into an adapter and the adapter burn your phone out with too many amps, the phone only draws so many amps and if the adapter can handle more, well good. It won't have to, that's all. The adapter will just run cooler and last longer. Can't hurt your phone that way. Cheaper cigarette socket adapters just cannot supply adequate amps to meet the phone's needs, and things get weird when they cannot keep up. With cheaper adapters, the Voltage can vary all over the place under load, and this can cause the phone to act erratic. If the Voltage goes too high over +5V, for example if the adapter is melting down internally, then the phone can be ruined by the over-voltage melting wiring or frying chips in the phone, though Motorola products traditionally have some protections in place...

Another thing - the screen issues you describe sound like they might be due to a condition people have reported with some chargers and docking stations, where the touch-screen sees the charger as GROUND for the touch-screen. I don't understand what's going on there, but it sure is real because I have seen it myself on my Droid3 when using some particular non-standard cable sets. The phone's screen will act really strange, sometimes not working at all, sometimes pushing its own buttons, sometimes turning the phone off and on, and combinations of the above. In my experience, if I try to charge my D3 with a SIIG supplemental battery block's cable plugged into any USB 5V, I get no touch-screen response until I unplug that cable, at which point it all goes back right again. No idea why. I don't understand these touch-screens anyway.

Lastly, if your bike has a voltage regulator in its 12V system, as it almost has to have, it might be worth checking that out to make sure its providing stable 12V. It might be spiking the voltage up and down round 12V and the bike wouldn't much care. Some voltage regulators always do this, others work better, all depends on things like wear and original build quality. Advance Auto's little charging system test computer can check it in a car and print out a spiky graph, for free. Don't know about your bike.

Ill run these steps once I move my data to the new phone.
I plan on wiping it and installing an FTP app and make it into a low power 16Gig FTP home server for backups from inside a fireproof container.

I have that car charger from Motorola and my phone can still deplete the battery plugged in.

Bikes are notorious for "dirty power", so I could look for a way of getting voltage regulated "clean" 5v 1A solution, but that's another thread on another forum.

It's also worth noting that with USB debugging turned on, my D3 would not charge at all with the car USB connection.

Turning USB debugging OFF solved the problem.

Were you using the dock or a usb cable plugged into a 12v->usb converter? Also, was it a Moto converter and cable? I've never had this issue with the OEM dock, cable, and converter. For me, turning off debugging was a bad idea since I'm always trying something new and having to undo my steps.

My car has a built-in USB port, and that was what I was using with a standard USB cable. When I plugged the D3 in, it seemed to indicate it was charging, but the battery always drained. It was very frustrating. I installed an APP called Battery Spy, and I could see that when I first plugged the D3 in, it went to charging state and flipped back and forth between charging and discharging several times before settling into discharging.

When I turned off USB debugging (which I turned on in order to gain root) then it charged continuously. This was true before the OTA update and after.

I hope this helps. It's easy to test using Battery Spy or any other app that can show the instantaneous charging state. I don't use a car dock or separate car charger, so I don't know if the behavior would be the same.
