Were they flying at 600 metres above ground level, 600 metres above the takeoff point or 600 metres above sea level. What was their altimeter calibrated to?

No.

All good points. But I think you will find that they are actually LiHV batteries.

:) Indeed. I am retired and my whole life revolves around the Hobby I stated in my 20s. I hate to think of how many $s I spent in this Hobby. Take care during this pandemic. It has reduced my flying hours. But I can still fly drones and helis in my Kitchen. :)

Sorry My post detail was aimed at the OP. I have cut off the part I posted re your comments for you and put it again here. Let me know if I have misrepresented anything. It's not clear to me what was "Tongue in Cheek" (Cynical) and what not. You can power up the drone without the controller...

"it shook with just the quiet props on it," What do you mean by this? Have you been running non OEM props?

You have mixed voltages up again. No. nothing bar a major catastrophe will get the Battery to 0V. They are not Lead Acid, not NiMH, not NiCad not LiOn. They are Lipos. LiPos have a bias Voltage of 3.0V that is they are past flat if you get them to 3.0V At 3.0V and below the chemistry is...

That is not correct. I think you are confusing 0V with 0%. I find that most drone flyers do not understand LiPo batteries. Those of us that fly electric helicopters and Fixed wing, Prop and EDF know full well not to discharge the LiPos below 3.7V per cell. That is about 30% remaining charge...

Then he is a very poor electrical engineer and needs to revisit his knowledge on LiPo batteries.

What you say is correct re LiPos but Laptop batteries that last many years are not LiPos they are basic LiOn with a different chemistry and don't have the same What Hour storage capability of LiPos.

There is much incorrect information on the net. It is not safe to discharge a Lipo Battery to 3.0V If you read 3.0V on a Lipo after load has been removed it has discharged well below 3.0V and is permanently damaged. You should never discharge a LiPo below 3.3V It damages the Lipo and reduces...

You can leave them at this percentage for an extended period. So their is no real urgent requirement to recharge them. 30-40% is the optimal discharge level for battery longevity. Every time you discharge below 30% it is reducing battery cycle life, for DJI HV LiPo batteries. The Mini LiOn can...

Make sure that you iPone has all other apps closed. (maximise available mem) turn off bluetooth, turn off wifi. Then try it again. Cheers

The drone automation relies on the compass not GPS for direction. To establish direction from GPS requires the drone to be moving at a reasonable velocity. Hence GPS cannot establish direction in a hover (The first thing it does in a RTH on signal loss) Without GPS only Manual flight will enable...

You need to understand something the misunderstanding is on you. You are well respected here and few with point things out when you are wrong. And you will invent reasons why they are wrong. So you actually bully those that disagree with you. As they stop doing that and you keep inventing...
