Darwin - What's your wattage and battery life like?
I picked up a used Darwin last week and the battery is not lasting as long as I'd expect based on the few reports I've seen around the web. It seemed like I could expect around a day per charge. I'm getting in the neighborhood of 4-5 hours when vaping between 8.4 and 10.5 watts. I probably take 5-10 tokes a few times an hour.
I'm wondering if my battery is just ready to be replaced. What wattage are you guys using and how long are you getting between charges?
Hum....sounds like you may be using a LR atty/carto...??
10 watts....1.5 ohm atty...... = 3.88 volts at 2.58 amps
LR's drain batteries quicker

Indeed I have. I've been doing the 3.7v/1.5 ohm thing until now. I have around twenty new 1.5 ohm Cisco 306s left in my stockpile.
Is LR the culprit? Seems counterintuitive to me, like having to produce higher voltage would shorten the battery life, but I guess I don't know how the internals work to make such an assumption. If LR is the culprit, I guess that gives me an excuse to try out an HH357.
You might want to try a 2.5 - 3.0 ohm atty....I think you will see improvement in battery life...
Have used 3.0 ohm for over a year with the Darwin.....that is all I use at 8.4-ish watts....
8.4 watts at 3.0 ohm = 1.67 amps with 5.01 volts.

OK, I guess it's time to order a HH357 and give it a try.
It probably doesn't help that the particular Cisco 306 I'm using right now is measuring in at 1.2 ohms.
I would say that is definitely the problem. When I use 2.5 - 2.8 ohm cartos/attys (and I am a HEAVY vaper) at 8.5 watts, I will get 21 - 22 hours on a charge. When I use dual coil cartos (1.5 ohm but because they are dual coil, they are not LR's) at 12.7 watts, I will get 15 - 16 hours. I take a puff every 5 - 10 minutes.

Thanks, guys. That's reassuring. I'll pick up a 3.0 ohm HH.357 and give it a shot.
Now if Avid Vaper would just finish their maintenance and put their site back online...
Yeah I got mine on Friday, and I have used pretty exclusive, all I use is 2.5 ohms or higher, and I cape at 10 watts, so far I have been charging it every night at bedtime, and the battery meter says its half full.
