Just updated mine. Battery shows full, although it has been in the fly for several nights and I used it for several bowls already. Not sure how many, but would have thought it would show partially discharged.
Turned up to high, 111% and first hit-----nice cloud from a nearly spent bowl. Seemed very nice. Need a refill, back soon.....
Edit: fresh bowl, first hit------extremely nice. I could not draw until the light went out, which is unusual for me...... Very tasty and good cloud, especially for first hit. Impressive. Took a second hit, and again could not draw until light went out, got a big cloud, but tasted charring this time. Sure enough, when I stirred, it was charred on the bottom of the bowl (not full combustion thankfully). I have never charred a bowl on the FF2 on the second hit (I can do it with the FF1 tho!), and maybe not at all (don't remember doing it). So, there is loads more heat. I love it. Might need to be careful how dense you pack now if you turn it all the way to high and 111%, we'll see.
Frankly, I am surprised there is this much difference. I was skeptical that the app would improve the device this much, but early indications are extremely positive, for me at least. I realize I've only done a few hits, but there is significant difference. Hopeful this makes the FF2 more user friendly for those that have not been getting the performance they had hoped for.
Edit 2: Holy Shit!!!! Hit number 3------OFF THE CHART!!! After the second hit, I stirred and this time lightly tamped instead of dense, and again couldn't draw until light off----- no charring and an ENORMOUS HIROSHIMA-LIKE cloud!!!
I swear I feel like I got a new device. And I wasn't really unhappy before. But, I was never super impressed with the vape either. Underwhelmed would be a good word. Possibly because of anticipation and hype etc. Regardless, I hope this isn't some strange anomaly I am seeing here. Using the same flower etc, so nothing else really changed but the app, so I don't see how it could be anything else....
