<pre wrap="">Hi,
Anyone knows how many mA the GTA04 needs with GPS on?
I have a charger that provides up to 650mA, will that suffice?

It is enough, but on dumb chargers you will need a USB-cable with shorted D+
and D- or you can try this udev-rule:
SUBSYSTEM=="power_supply", ACTION=="change",
DEVPATH=="*power_supply/twl4030_usb" ATTRS{1-0048/twl4030_usb/id}=="200k",
ATTR{../../max_current}="500000"</pre>

Hi, <br>
<br>
Thanks for the hint, but it seems to work even without this. Saying
it's charging with 240mA.<br>

Problems I noticed:
After resuming from suspend power consumption is crowing more and more. It
sometimes reaches more than 500 mA with display on and then it doesn't charge.</pre>

I've run into this problem before when connected to the laptop,
sometimes it wouldn't charge.<br>
<br>
Have not seen that (yet) with QtMoko v52, but then again I've had it
only for a few weeks, and I always used the OpenMoko charger. Today
though it charged completely full connected to the laptop.<br>

If battery charge is below 60% it regularly disconnects USB and does'nt
charge. You have to reconnect the charger. I have the suspicion, voltage
reduces with discharging battery too and gets to low.</pre>
