It's quite easy to figure out how it works, the point is the information provided is useless.
Someone here mentioned a possible solution - to take a spare battery with you just in case, and that could be a workaround to the problem.
Without knowing, he admitted the battery gauge is useless.
The more I think of it, the more I get frustrated about the idea behind this gauge, and I got to a new conclusion:
It shows information using incompatible units. While it tries to display how much more can you go with your current settings,
it shows this information in percents, and not in time (or something else similar). And you can never know out of what these percents are.
If you put some atty and get 60%, there's no way for you to know what is 100%, so you cannot calculate how much battery you actually have remaining.
You also need to take into account there are many devices with battery gauges around us, all works the same but the Provari. You can never adapt.
Now, as I mentioned earlier, you can take a spare battery with you, you can spend some time trying to adapt to the new display, but
are we supposed to change the way we think and see things for the sake of a
device ? It's quite the contrary - devices should adapt to us.
Bearing it is compromising for the sake of someone's idea. More is not always better.
I can say that with the new Provari I never knew when my battery was going to die. It just happened. With the previous model,
we had at least some flashing lights just before that. Now it's gone.
Someone mentioned that it's great for him, since in comparison to the previous Provari, you need to click less. Well, here at least we have something
to compare with, not as with the new battery gauge (remember ? 60% out of what ?)

But with the previous Provari, at least these 9 clicks showed the information you need, which is the battery level. With the new one, this information is not
available in any way. I also think the previous Provari interface design was genius. It was a huge innovation in comparison to what you can achieve
with a single button and a 7 segment display. With the new oled display, it could be perfected. Unfortunately, this is not the case.
