That's some shitty battery life I must say! Getting around 7-8 hours on my 19 Mk6 with somewhat intense use.RDClaes wrote:They are 2900mAh
I ended up buying the 2nd battery. I was getting 2-3 hours on just the tablet battery. Now I'm getting the 4-6 easy and it's much better for my use.
CF-20 Review! The Good, the Bad, and the Ugly!

Re: CF-20 Review! The Good, the Bad, and the Ugly!
I think part of the reason for this is a few things:
The CF-20 is thinner so they thinned up the battery as a result.
They aren't using 18650 cells because they are too big. For SURE you're comparing a 2900mAh battery to a 5700mAh battery.... That's literally HALF the capacity
Thanks!

I know that Rob, but still even with the dual batteries that's prettyRob wrote:I think part of the reason for this is a few things:

Well I'm talking realistic battery life too. I own a CF-19 mk6 and have a brand new battery with it. I never got 7-8 hours of battery life. I would get 4-6.
I bet with both batteries you'll get the same as your CF-19 if not longer. The little battery manager says I'll get 13-18 hours of battery but I know better.
If I dim my screen, turn off the 5Ghz radio, turn off the bluetooth radio, don't use the WWAN, I know I could get better life. I just do ALL THE THINGS!

RDClaes, you could probably easily double your battery life by tuning your power options.
I usually get 9+ hours out of my cf19mk6, especially for indoor use.
