[Q] Charging Craziness

[mattyv]

I can't figure this phone out with regard to charging.

1) Won't charge via computer USB (I've heard the reasoning for this - still seems stupid)
2) Charging w/ 1amp 5V wall charger - phone screen is non responsive to touch, but phone charges (unplugging it unfreezes the screen)
3) 1amp accessory USB charger, won't charge the phone at all.


Are the charging limitations software or hardware based. I can't come to terms with the fact that this phone can't at least charge by USB. It doesn't need to be lightening fast, but it should at least charge.

Is there anything that can be done?

charging by USB

My phone charges with just the USB cord and a PC, It is a bit slow to charge that way, but it charges. Are you sure you are using a powered USB port?

it will charge via USB, you just need to install the motorola drivers. it needs more current than the original USB standards allowed for. USB can provide that current now, but you need the drivers.

Not OEM

None of the above are OEM chargers and the cables are no OEM either (Wouldn't think the cable has anything to do with it).

Since i am out and about a bit, i have to have a portable battery powered backup charger, i also carry a wall/car charger that is capable of doing both at the same time.

cable has nothing to do with it. The power requirements are strict for this phone, and it's all down to the proper way to charge the battery.

I know for a fact that the generic energizer car charger i picked up with interchangeable ends for different USB types works perfectly for this phone. It might be worth it to just jump on ebay and grab another OEM battery instead of trying to run around with chargers.

have you measured the output of those 1a chargers? i have an adapter from china that says 1a but only puts out 0.3a and doesnt charge my atrix either.

I am still using the chargers I had from my blackberry 8900. The bb wall charger works great. The car charger (att) with the flip cover over a usb makes my phone hot as hell but it still charges.

Think i've also found that, once you have the motorola drivers installed on your computer, disabling the data connection to the phone (as in selecting "None" for the USB connection option in the notification pane after you connect the phone) seems to allow the phone to charge a fair bit faster over USB. Kinda makes sense too when you're thinking about it... since it wouldn't be constantly accessing the phone as a storage device.

Yes some wall chargers dont work i.e. the two I had from my Nexus One, BB chargers seem to work well as I believe they needed more juice to charge in the first place, for the usb cable, the best solution to try is getting the updated usb drivers as mentioned.
