Are you able to share your research? If litchi caused the problem it's unlikely DJI would have come to the party and concerned the repair cost.

A software application cannot cause damage to a battery. If your battery failed it could be from many things but using a software application can only drain a battery at the rate (ma ph) the hardware drains it. If you operate a lot of functions you will cause greater battery drain ( like constantly moving the gimbal, focusing, taking photos and running video, etc.).
Improperly charging your batteries or charging them with non oem chargers, not properly discharging them or operating in extreme temperatures can cause battery issues.
If a cell fails in a battery (there are 4 cells in each P4P high capacity battery) then you could of just had a bad battery. Just like a car battery failing from a bad cell.
Did you upload the logs to healthydrones.com as we could see the battery cells and status.

I believe even in using the Go app in some IOS modes it won't RTH if signal lost until mission completed. Remember, the AC gets uploaded with its mission with either app and is autonomous after that. The only difference with waypoint missions on the Go app is that you have to program the waypoints by flying to them and saving the points so if you lost signal, you couldn't complete programming the mission.
On the other hand you can pull up a saved mission that you programmed while in range for each waypoint, but on replay some waypoints are out of range.
I would hope though that the AC would abort any autonomous mission, whether it is waypoint or POI if the battery got low and subsequently returned home.
Remember, it is the AC that makes these decisions and acts on them and not the app. Therefore any issues/concerns lies in the firmware, not the apps.

As everyone has said here, it completes the programmed mission, signal or not.
It's kind of intended for out or range work, hence no RTH.
You can turn your controller off after hitting go, it will carry out the mission regardless.

Thank you everyone. I am starting to understand the idea of the process. It sounds like I should start and end the mission close to myself,...so the end of the mission is actually Home. Just concerned the way it signaled out the P3S as not returning home. And range is always a concern of mine. It seems even with the intilite range extender,....I can get about half a mile and thats it,......regardless of area. I am strongly considering the P3P or P4 as a needed purchase. Cannot decide which one to purchase. Understand value would be the P3P,...but the slight ($400) additional price gets me a better lens glass and front crash sensors.
Anyway,..thank you everyone,...especially the way point tutorial video. That was very helpful in teaching myself. This is a GREAT forum and teaching tool.

If doing waypoint missions you set the mission up to rth,hover or return to first waypoint.thats the best part about litchi is that even if you lose signal it will complete the mission and then end however you set it up to.

I want to party with you. You have a twisted sense of fun... lol
Kidding. The first few times it is quite a rush. I did one last night at dusk and forgot to turn on my lights. I could hear the bird , but couldn't pick it up visually. That was interesting to say the least. It went quiet as it rounded a hill and i was never sure it would come back until it just showed up 200 feet above me in a hover.

The only way I can think of where software could contribute to battery damage was if it forced the phantom to keep flying when the battery reached critical low, thus draining the battery beyond the safe limit.

Which brings up the question: Will the aircraft RTH when the battery hits critical level when flying a Litchi way point mission? Or do you need to plan mission within battery capacity limits.
My understanding is behaviour is identical to what is programmed to do under DJIGO app for Both Low and Critical battery Warnings..
"Smart RTH" settings in DJIGo app determine what happens on low Battery (like RTH). You asked about critical battery, depending on "critical low" level you had set back in the Go app (mine is at 10%) it would land in place, just like it would when using the Go app.

I have a Nexus 7 tablet and a P3S and I am fairly new. with FW upgrades I have been having more troubles I have seen discussed in many threads by people. So I am thinking about buying the Litchi app. I do mostly standard flying not many waypoints. So from what I have read it sounds like it is the way to go. Is there anything I am missing or need to watch out for. Also is there another app I should look into. Thank you this one group where people really help each other.

Just remember that in certain flight modes Litchi will not RTH if lost signal. So make sure all your missions END right by you. RTH still works if you push the button or flip the switch. But if your flying a mission and drop signal the AC will finish then mission the do what you have programed as far as getting home.
A good point.
So, if I out of Luck to cancel mission via returning the flight mode switch to P (or A), it will continue to orbit...
I don't have enough guts/suicidal mood to test it, but - will the Low Battery RTH doesn't kick in?
(OK, Critical Low Battery with immediate landing regardless where in orbit the AC is, is not a viable option most cases)

So if I am just flying with no missions missions and lose signal will it RTH automatically.

Where did you go? We would still like to see your references for the litchi app damaging batteries?
Sorry have been busy will find them again in 30mins has been about 2months since it happened
