So just confirmed that my Legend with FW 1.2-0710 displays a low battery error when the cells reach 3.2 volts. Both cells measured by a volt meter and a Nitecore Intellicharger. The battery indicator on the Legend reflected this.
@VapourFlavour – just to confirm, your Legend displayed approx. 50% on your batter indicator when the cells were @ 3.2 volts? Did the mod still fire? Did you measure both cell’s at that voltage?
Couple of things I would try. First is to perform a reset – this can be done by removing your atomizer, turning the device off, holding the +/- buttons until the Firmware is displayed then press and hold the fire button until reset has been confirmed. This will retain the Firmware but reset the settings within the board. You will lose you puff count if that is of any importance.
Should that fail to rectify your problem, I would reload the Firmware again. You can go back to a previous firmware if wanted. Just to note, as experienced with another member who failed to flash their device, ensure your computer is not performing any heavy tasks and follow the update instructions. Remove atomizer and batteries, press and hold +/- buttons and plug in the USB and launch the update application. Click the Start Update button only once….multiple clicks will result in a failed update. Should you have problems with the USB cable, I know a member who has many spares
I have run both FW versions 1.1 and 1.2 along with the original that came loaded from the factory. There was battery improvement from the original to 1.1 but I did not notice any improvements with battery life when updating to 1.2. There might have been improvements but they could have been subtle.
