Charging JBR | Rockbox doesn't agree with itself

(1/2) > >>

boxmonkey:
I'm having a possibly minor, possibly not minor problem with my JBR.
Version: r12762-070314 (p.s. having the version screen automatically flip to the credits after a few seconds makes getting this information very obnoxious!)

I have this version flashed, so this is what it's running no matter how it is started up.

Here's the problem: When I plug in my JBR 20 to the charger, it "boots up" into the special charging screen, which says my batteries are almost completely discharged, currently it says 9% and it slowly ramps up to about 30% and then wavers at that point going up and down but never really making it much ofer 30%. Now, from there, if I press "ON" and start up JBR the rest of the way, it shows that it's charging, and the number initially seems to agree, saying the batteries are at 9%. Then it quickly ramps up all the way to 100% and says it's trickle charging.

What's going on? Are my batteries in need of replacing? Why doesn't Rockbox agree with itself?

Any help would be appreciated!

gnu:
As far as I know, the battery capacity detection in rockbox is working quite poorly on all targets.
-> try charging with the original firmware
-> or charge with rockbox and simply don't give a *** about what it displays.

boxmonkey:
hmm, interesting. Good to know! I foolishly did not back up the original firmware, so I guess I'll just have to put up with it. :)

TAC109:
Is your JBR v1 or v2?

Charging in the v1 is done by software (Rockbox), but in the v2 is done by the hardware (Rockbox just reports the state of charge).

boxmonkey:
It's a v1.
