FixHub completely dead after being left unused for about 5 months?

Hi,

after having not used the FixHub for about 5 months (put it into my drawer with about 70% charge), i wanted to solder something - and to my surprise the unit was completely dead (in my living room, so not cold/unheated).

I could revive it by charging it with a USB-A to USB-C cable - but that was a shock :(

So, i guess, my question is:

Is this expected? Is there some kind of "vampire drain" that empties the battery slowly but steadily?

No offense, but the whole product is a bit of a letdown - one of my tips i ordered regularly disconnects when i exert the slightest pressure, the other doesn't - everything is acting slightly more erratic than i would like it to (especially a) at this price point, b) this being an iFixit product) and if i now have to take special care of the FixHub once in a while... don't know, i just don't need another Tamagotchi i need to tend to at this point in life vs. something i can just put in a drawer, forget about it and be able to use it whenever i pull it out. Sorry for the rant.
