Possibly a loose battery?
Hope DJI can figure it out for you? Good luck to you and hope you get it sorted

just a suggestion, because you don't know how to look at the logs means you haven't done it and it is a good practice to review logs after every flight (I think), you may have been able to detect a defective battery and saved your P3 some pain. post flight checks are just as valuable as pre
Good you have insurance, you'll be back in the air soon..
I had a similar incident, only my altitude was 120'! total loss
It was
Related to "TheRealNick's" post.....
Some people think a battery that was charged several weeks ago is "fully charged". After 10 days the battery will self discharge and go into storage mode all by itself. What did the app say? Did you look at it before you flew?
Seems there are lots of crashes where the operator suggests they took off with a battery at less than full charge (usually around 50%) and then the Phantom dies and crashes shortly after takeoff. Seems to be a pattern. In this case, the OP says the battery was fully charged.
We don't yet have logs to verify this however.
Pure suspicion, but it could be a combination of the batteries electronics not reading the voltage correctly since a battery can show it's at full charge yet have a reduced capacity......and the operator not charging the battery right before flight. I can, for example, charge a car battery with one dead cell to 13 volts. The voltage is there, but the capacity to supply current is not. In a case like this, the Phantom just might climb for a few seconds then unexpectedly exhaust it's capacity (which was improperly indicated to begin with). Voltage still might appear to be within acceptable range.
I'm wondering if there's some kind of bug in the battery firmware that is giving false battery voltage readings....well....ok, correct VOLTAGE readings maybe, but not fully considering CAPACITY.
I think load testing your battery every once in a while (clamped down to a bench and run at full speed until it hits the low voltage warning) might help in some cases. You could at least measure the time it took to go from indicated full charge to low voltage warning. A bad battery will have a much shorter time to go from full to low voltage under those circumstances. (Loaded voltage test)
I don't know what electronics are inside the P3 battery but I would think it contains resistors to carry out an internal load test...or at least a calculated load test by measuring the indicated voltage vs time to discharge / recharge the battery against a data table.
However, in any case, the Phantom should not simply lose power and fall from the sky with no warning. It would seem that an error would have to be in the battery firmware that misjudges the battery voltage. The logs might (or might not) reveal this. Or, a connection loss at the battery terminals. Again...the logs should show a sudden total loss of data.
Not sure if any of this applies...just thinking about the problem here. Seems to happen often enough.
Until an operator posts up the logs, I tend to lean toward user error. Nothing personal Chris.
Just to be clear, the SD card with the log files is internal. I.e., it's not the SD card in cameraNo logs available. Sd card is damaged.
internal to the aircraft? the p3p is at the repair shop, not in my possession for a couple weeks.Just to be clear, the SD card with the log files is internal. I.e., it's not the SD card in camera
Yes, internal to the A/C. Maybe it'll still be the same SD card when you get it back. But, if they replace the board probably be a new SD card.internal to the aircraft? the p3p is at the repair shop, not in my possession for a couple weeks.
Pm me how to post the logs please, if uou got time. This same thing happened to me two days ago! Just took off heading forward and fell straight down battery still attached and full chargedPost your logs so we can review them. Otherwise, it'll be tough to figure out what happened.
Additionally I checked a short while ago on the battery, I plugged it in to recharge hours ago, and found the 2nd led segment away from the batteries power button to still be flashing green. I tried unplugging it from the charger, waited a few moments and replugged it into the charger and it is once again flashing green this same l.e.d. segment. This battery has only been power cycled maybe 3 or 4 times since I purchased my Phantom in the second week of December of 2015. Could it be that this battery has some sort of defect? I'm not sure how anyone can access the data that I viewed on healthydrones.com regarding my flight data but if you would like to review it let me know how to make it accessible to you (screencapture, etc)
