Well, if I am at home, I put it back to charge after every 2-3 bowls. So in a way I, too, charge it XX number of times a day, but that is really meaningless. What matters is if there is consistency in
a) how long it takes to deplete charge (there is not, because this is subjective to usage patterns)
b) how long it takes to charge a depleted battery* (should not be subjective to usage patterns as long as the unit is being placed for re-charge at the manufacturer's recommended level, which is when the battery indicator is at 1, or a few bowls after that)
* by depleted battery I mean charging it when it comes down to battery indicator 1, at least. Typically, like Charlie says, it is possible to get more bowls than 1 at that level.
FLskwat: you are charging at level 2. that is probably 2-4 bowls before I and, from the sounds of it, Charlie charge. So your 2:30 hour charge time will be below the time it takes to charge from battery indicator level 1 and below. Though, your charge time is very useful to know, so thank you for posting. I think, from your charge time, it is probably okay to assume that the 4 hour charge time may be an over estimation. Strange though that they would do that but exaggerate run-time.
If one is getting 1 bowl per level of life, plus 2-5 bowls at the last level, that is anywhere between 8-11 bowls per charge. If FLskwat is reporting 2.5 hrs of charge time from level 2, if this is an average indicator of charge time (why should it not be), one could assume about 3 hours of charge time if one is truly waiting for level 1 plus 2-3 bowls at that level before recharging (?).
If so, at six charges a day, that is 18 hours for charging purely. Are you really spending 18 hours a day charging? That is what I find 'off'. (And, perhaps, this is exactly what you are trying to convey as a disadvantage to the vape!)
It is definitely possible though: assuming all of the other time is spent vaping, that is a full battery charge used up in an hour. About 8 bowls an hour at least. a bowl every 7.5 minutes, at the minimum. This pace is assuming one is vaping all day with the Solo only (well, the 6 hours that remain outside the 18 hours required for charging anyway). This level of tolerance is definitely not unreasonable, nor necessarily uncommon, ime, and I am often at nearabouts this level myself and have been at higher levels of tolerance when I was younger, but
a) I think while the pace of a bowl every 5 minutes is common & reasonable, I find the logistics around it in this situation a little unreasonable, but that could just be my issue i guess (maybe I am just over-thinking the whole thing-- something I do often!)
b) I think this extent of usage should be explicitly stated because it does affect one's impression of the vape's usefulness
I will say, however, that when on the go and not around an outlet, I do finish off my battery fairly quickly and end up resorting to joints. So I am definitely not trying to say that the stock battery supports heavy usage in a convenient way.
Anyway, hope my posts are not annoying! Just trying to get some folks involved and figure out (for those who are considering buying this vape) what the battery issues are, how applicable they may be from user to user and what they can expect from the battery from a usage perspective.

Also confirmed over the last few days that grinded herb does work better than whole nugs. Nugs DO work, just I don't think the vapour density and quantity is as good as finely ground. Nugs give ok to good vapour, but ground gives clouds.
Thanks for that piece of information. I usually use solid nugs since that is more convenient, esp when moving around with it.
Is the above true for some of the other users too?? Being able to use solid nugs is one thing I really love about the Solo and the HA as well. I don't think I ever experienced ground bud giving more vapor than nugs in the HA, but I could be mistaken (not sure if I ever paid attention).
And yeah, I definitely think it is a good idea to have 2-4 extra stems lying around! Sorry that one of your's broke!
hahahhehehoho at last mine arrived a couple of hours ago. I'm very satisfied, and it's smaller than I was expecting. I love the vapor from this thing- I don't think any of my other portables can compare. This definitely has a strong role in my arsenal. I've flown through the half charge that it came with and have tried 2 bowls of whole buds, and 2 of ground buds. Not enough to contribute any valuable experiences, except to say I'm feeling pretty damn pleased with my initial findings in each case. Both my stems are loose, but I've been able to hold it in place at the elbow easily enough with the finger of the hand holding the unit. I don't think it's going to be an issue, although it would perhaps be nicer if they did snap snugly into place.
