It turns out that oleds + rgb is my problem. I will update you if it is better after desoldering rgbs and replacing oleds with nice!nano
Right now I am using 2x 100max batteries. The life time is really poor - not even a day. Oleds are enabled, rgba is disabled. I am planning on replacing the oleds with nice!view. However I am worried that this will be not enough. Last resort is printing a case with some space for a bigger battery, but maybe you guys have other suggestions? >

If you have the RGBs soldered, and external VCC on, they are drawing roughly 7-8mAh per LED in standby keeping the communication on. 
And as said OLEDs are also a battery killer. With nice!views instead, and no RGB soldered, it’s a whole different story. >

Wow, thanks for the info! I was not aware of that. I guess it's desoldering time :D >

That should at least net you two days or possibly three. >

haha I finally finished mine recently too. Maybe you could get a bigger case that could fit larger batteries. I'm guessing you have small ones under the microcontroller? >

Yes, right now I am using a small one. I am going to replace them, however I need a nice case first >

maybe you could replace the stand-off screw things from the case with longer ones to make some space below the pcb. Sadly it would be less low profile >

Making it wired/j >

I have a wired one already :) >

They look so good! I'm about to make one too, although I've had an Iris already but sold it because I could not get used to it... Let's just try again :p >

I like de idea of this board, maybe if it had a better battery or a more economical circuit it would be perfect
