Strange charging problem - GSM-Forum

SaltyNYH · 02-18-2003, 11:25

I wanted a headset, what can charge the battery until talking on the phone. So i soldered the charger into the headset connector: 1-2: GND, 3:+Ut.
But not works with C25 v46: charging only by power off.
On A35 works fine.
(The normal charger can charge when i talk with the C25!!!)
Where is the problem?

The problem is current. You have more good battery on your c35 then on your c25. The message "Batt. Empty Pls Recharge" is on display when phone detects volatge decreasing while current increasing.
