Jam Battery Meter Problem..

[GFX]

Hi everybody,

I'm having a strange problem with my i-mate jam.. I've replaced the battery 2 months ago with a new one. The new battery works like a charm.. I can make calls with only 6% of charge..

Anyway, about a week ago, the battery meter started jumping all over the place; all of a sudden the meter would show 100% charge then change to "Charging" state with 0% charge (both the primary AND the backup battery)!! Then in a while change back to 100%, then eventually it goes back to the real charge value (65% for example).. And then it goes to 0% "Charging" and so on.....

When I connect the charger, the device shows the right charge value, but sometimes it gets stuck @ exactly 81% even after 2 hours of charging, the LED is constantly yellow as usual but I can see a green flash every 8 seconds or so..

Sometimes, the device behaves correctly and charges to 100% without any problems, but when that problem happens it gets so irritating and annoying, and I am totally confused about it coz I can't make out a logical explanation to why this keeps happening.. I didn't install/uninstall any new programs.

Do you guys know anything about that problem??

Thanks ahead for your replies..

P.S: here's my ROM info:
ROM version: 1.11.00 WWE
ROM date: 03/14/2005
Radio version: 1.11.00

does the old battery also behaves like that?

No, the old battery never behaved like that.. It's a new problem. Anyway, I discarded the old battery so I can't tell if it behaves the same or not.

As I'm writing right now, the phone is connected to the laptop via USB cable, the LED is yellow and the "Power" menu shows 0% battery and "Charging" status! It's been like that for almost 30 mins now! I have no idea what's going on, the phone appears to be charging but the power meter indicates 0%!!

Could it be something with the charging circuitry??

Sound like a typical hardware problem.

It could be. However, the meter has been behaving normally for 2 weeks now. And I'm linking the problem to low temperatures. Apparently, the new battery is of poor quality, so when the ambient temps. go below 12C the metering circuit starts showing false values.

I'll keep monitoring the problem and report if anything new happens.
Thanks all for your help.

i'm not sure but here in New Delhi when the temperaures have come down to almost zero, my device sometimes starts behaving like this but it corrects itself in about 5 seconds.and the battery is what was bundles with it and has been working perfectly from past 2 years.
