Everyone may know this but me - if not, hope it's of interest:
Some time ago the Go App stopped displaying the remaing battery life remaing on their battery page telematry. I'm not sure how accurate it was or if they thouht it might be confused with percentage of charge, but it's gone.

After a Litchi update I noticed when clicking on the battery icon that the battery life info is there. It must still be a field avaiailable to display in the SDK and Litchi used it.

Thanks Litchi!

Nice find, good for you Litchi customers...
I wish @DJI would leave "awesome" alone...
But they continue to Frick and Fumble with their firmware and app.
I noticed they removed my favorite grid lines too, in the latest offering.
We need a totally customizable app, that allows us loyal users more choice.
Tired of being spoon fed, narly tasteless pablum... Ha

"I noticed they removed my favorite grid lines too, in the latest offering. "

You maybe just need to reset them, still showing as a choice under Camera Menu/Spanner/Grid

Yeah, but only two choices left, there was a third choice with both diagonal grid and horizontal lines.
Much preferred over these two burnt-offerings..

Are you videoing or targeting? Have you converted yours into an Apache?

Yes, and it's deadly... Hahaha

Rnfaust, how much time can your bird spend now in air with 75% of battery life remaining?

Vladlostov- the 75% is the battery life, the battery charge left is indicated top right being 96%. The battery life and battery charge indicators are 2 different things altogether. It's something I've seen many people get mixed up/confused with

I can't answer the air time question as I never fly much below 40% charge. I'm also not perfectly clear on how they calculate battery life remaining (75% - now down to 71%). As @TechReviews points out, battery life refers to remaining service life, not runtime on the current charge. It can't be the voltage variance between the internal battery cells as there are similar readings in both my new and old batteries.  Battery life could be the battery's ability to reach full charge, but more likely it's the result of an algorithm I've seen in some sophisticated automotive battery test equipment that use conductance technology to determine battery life. It is a "smart" battery after all.
BTW: I do like having an extra battery now.

TechReviews and Rnfaust,

Thank you for explanations, guys.

Battery life may use several factors, one being how it has been charged/discharged through its life.   Other aspect is estimating its available capacity to hold a charge based on voltage, time, current draw and internal resistance.   IR is defined by change in voltage based on current draw.  As batteries age, they develop increasing internal resistance.
I'm guessnig the life reading is based on recorded usage, much like oil life reading in a car based on how you have been driving the car.
