How do you know it doesn't charge the battery? IIRC, we had no charge indication of non-GTA02 batteries a month ago. We didn't even light up the charge LED while charging non-GTA02 batteries, did we? It would not be difficult to establish if your GTA02 charges your BL-5C battery or not - simply try it out! Use and charge with your GTA02 like you normally would. After a week, tell us if your GTA02 stays on when you unplug USB/charger power supply. Because even if you suspend the GTA02, a BL-5C won't last for more than 4-5 days without being charged. Or you can measure battery voltage before and after charging in the GTA02 - you will find that battery voltage increases during charging. Heck, your Nokia phone probably has some sort of charge level indicator that you could have use for before and after charge level comparisons. Or you can look at the schematics[1] page 4. The coulumb counter is not connected to the battery charger (PCF50633). Go ahead, search for R1769. You'll see it says NC which is short for not connected. Looking at the component placement drawing[1], you'll see that space was allocated for R1769 below U1701. And indeed that position on the PCB is empty (GTA02 date code 20080722): http://nospamnospam.homepage.dk/hardware/GTA02A6-R1769.png GTA02A5 pictures are here (you want the 'CS' ones): https://people.openmoko.org/tony_tu/GTA02/hardware/GTA02/A5/ So please, can we see an end to this totally unfounded misinformation about not being able to charge batteries other than GTA02 ones?
