I got my iStick 2 weeks ago and love it but I'm not sure I'm getting the battery life I should. I see others talking about a day and a half --two days and I don't get anywhere near that, I am a heavy vaper( about 7 ml a day) and I realize it's hard to compare charge times as some chain vape, some are light users and everywhere in between. Since I was planning on binge watching the final season of Boardwalk Empire today I thought I'd chain vape from a fully charged iStick until it ran out-- see what would end first--eight hours of the show or the iStick. At 5 hours in the iStick died.
I was using a Protank 2 with a rebuilt coil --1.2 ohms at about 10 watts. Do you guys think 5 hours is what I should expect on a charge with that setup or could my unit be defective?
This thing is great overall though. No thread problems as I decided to use the 510-ego adapter from the start and not take any chances (Protank with beauty ring looks great). Love the pass through ability and it is in a class by itself form factor wise IMO.
Ya it seems something is draining your battery much faster than ti should be discharging. Could most definitely be the adapter. Could also just be a bad battery that was not properly cycled from the get go.
Out of the 3 iSticks I have received, all of them arrived fully charged. This is a huge no no. This type of battery chemistry has what we call a storage charge. This is typically between 3.7 - 3.8 volts. It is the ideal voltage to keep at when not being used for a period of time. Having a this type of battery at full charge and not using it has a negative impact on the longevity.
I work in the electric rc hobby dealing with much larger lithium polymer batteries. Although the chemistry is very safe and powerful, their are things you always have to watch out for.
That said, all 3 of my iSticks can easily blow through 8-10 mils on a 1.8 bvc head around 12 watts before even batting an eye. I go through about 6-8 mils a day, usually staying around 10-12 watts. I charge mine every other day at the most, usually can go two full days before needing to charge on the 3rd night.
Here is a little tip. These batteries develop a cycle very early on, and there is a way to properly break them in. Kind of like a new cell phone. For the first few charges, let the battery completely drain before giving it a full charge. This sets the battery up to get accustomed to going through its full life cycle and helps with long term life span. After it has been charged 5-6 times, this is not as crucial. But, if you get a new battery, vape it to only half charge and then charge it every time, the battery never truly knows it's potential life span as you never let it fully drain.
Also, I always disconnect my atty when charging, as well as turn off the device. If you follow these tips, you will see much better results. Only charge when FULLY dead if you can get away with it. Charge it without an atty, and turned completely off. Make sure it gets a full charge before disconnecting. Other than that, coming with a full charge instead of proper storage charge was a mistake form the get go from the company.
Enjoy your iStick, I sure as hell am. It is nice after using all of my mech and sub ohm drippers to be able to pick up this little guy and get a nice warm satisfying vape with battery for days.
