Good news, you're likely wrong :)
Don't project the current draw when on the charger to when on the battery.
It's very normal for the charger portion of a PMIC to be extremely
in-efficient. I typically see less than 50% efficiency on chargers. The
power system will be optimized for running off

Thank You for the information.

Guys,
you really need to set the terminology straight here otherwise we spread FUD.

Feature phones only differ between talk time and standby time.
For us, it's a bit more complicated, since we have more modes.
Can we agree on the following:
usage time = CPU is powered on, lots of peripherals have power and you're
Great summary Michael, and a good discussion. It would be nice to see
the ability to support other fast chargers in the future. That is one
of my pet peeves about cell phones is that it seems every single
company(and often even every model made by that company) has it's own
specific charger

That's also something I'd like to know as my Minty Boost supposedly
does up to ~250 mA and I'd like to use that much if possible.
The Neo 1973 doesn't have the necessary hardware to detect chargers,
though, or does it?

I would disagree that this state(regardless of what you want to call

majority

Can the Freerunner resume on incoming call? If so, someone could
suspend the device and toss it in their pocket/purse, reap maximum
battery life AND keep the primary functionality intact. If it can't
resume on incoming call, I'd agree it's essentially

Are you referring to changing using different current draws? IIRC,
someone was tweaking uboot because it wasn't drawing the full 100ma,
only 20 or so, and

standby time = 10 hours

Hi everyone,
With input from the experts who designed the system, I've tried to
document precisely how charging works on the Neo Freerunner.
I welcome your feedback:
The Neo Freerunner charges the battery when 5VDC is provided at the USB
port, whether from a computer USB port or from a
Hi Michael,
This is a good start, very informative. Some good additions, I think,
would be:
* Why does computer/usb charging max out at 500mA? is that a
limitation of the USB spec?
* you mention 'other manufacturers' that 'identify their own chargers'
with various resistors... if

What do you mean? Autodetecting that a computer is the host depends
on some digital communications rather than measuring a resistor.

This could be done even more simple:
- Download and install the program
- Connect the charger with the unknown resistor
- Click on the button Get charger ID
- If a valid charger ID is found, the button Add this charger
becomes clickable, else it is grayed out.
What do you think?

You can only probe the pins that have the appropriate hardware interface
to them. This may be all, but can't be taken for
