IBattery had 3 bars. But still says 0%. Definitely some kind of problem. I just dropped the app. Battery's ruined. Only 2 weeks old
Sent from my SM-G935V using PhantomPilots mobile app
I am quite curious how the battery can be measured at 0% - in theory you wouldnt be able to read it because it has no energy left to send the reading. Assuming the 3 bars is more accurate and you can power-up, what does it show in the DJI Go app when you tap on the battery icon so it shows the battery in detail - each cell voltage, charge cycles etc? Did you try recharching it, or leaving it on the drone and draining out the 3 bars? Most smart battery monitoring measures the usage and calculates the remaining usage.
It may be that it just needs to re-calibrate, DJI somewhere I recall mentioning every 30 or so charges to discharge down to 8% and re-charge to re-calibrate the usage.
