    So today I installed the new iOS app. I did not fly since installing iOS 9. On my first battery I flew with my new iPhone 6S plus. The battery was at 57% because they had started their auto discharge from sitting a couple of weeks. I figured I would run them down before doing a full charge and check out the app. The first battery was fine. I then switched to my iPad mini 2. This battery was also at 57%. I took off went up to around 375 feet all the while I was going forward and turning to the right. At about 30 seconds in I got a critical low battery warning and the craft started going crazy. The gimbal started leaning to one side and went into an arc to the left. I tried to bring it back, it was only 500 feet away. It was flying sideways even though I was not imputing that into the controller. I got disoriented and then it lost signal and went down. The weird thing is on Facebook I have now seen this same problem twice. Just wonder if anyone else seen this.

    I would also like to add that this was my 109th flight with over 1,150,000 feet flown without any problems or a single crash.

    I have seen several other posts not related to the new app, but related to starting a flight with a far less than full batt causing issues.

    Great. Wish I saw those. I thought it would be better to drain down before recharging.

    This is a known issue It has been reported in the forum over and over, i don't know if Dji mentions it somewhere i think is saw it somewhere. In any case never fly with less than 100% charged battery. The P3 needs all the juice it can at take off (a lot of Amps) and people reported that u can see the bat levels going very low suddenly during take off or at full throtle asend. Bottom line is the bird does not like it. Hope that u recovered your bird and that the damage is not grave.

    It is demolished. Sent it back to DJI for repairs.

    As soon as I read this part, I knew the rest of your story. I agree with what the others said and what has been noted on the forum many times. Begin with a fully charged battery.

    How bad was the damage when it went down?

    EDIT - Just saw your follow up post. Sorry about the heavy damage. I hope they fix it up quickly for you.

    Any battery, including PBs, will register a drop in voltage when under load - the heavier the load the more the drop.

    While it is desirable it is not always practical or opportune to take off with a full battery. In those cases simply take off gently and fly to your target slowly. Do NOT zoom up and out at full throttle!

    I am approaching 300 flights and I frequently land and take off again - when I need to change a filter, swap out an SD card, or toggle between Go and Autopilot - and I have never experienced this sudden critical power situation. Take it easy with your P3 - it is a flying tripod, not a hotrod.

    Mine crashed after wind gust and dji repaired for $181. Took about 3 weeks. They basically sent me a new one, camera, body and all.

    A product that can't perform reliably at 57% battery level is not a well designed product. It's within the safe operation range and should perform the same at 100% or 50%. This should not cause any logic issues within the product, it shouldn't behave irrationally. While it's power may be lower, it shouldn't perform actions not input by the user.

    I have used mine as low as 40% for a quick 2 minute flight in the backyard. Nothing happened that I didn't directly input to the controller. Although, I haven't tried that with iOS9 on my 6+. I have resisted that upgrade due to all the reported issues.
