Hoping to find some advice here. My Whoop 4.0 is really on its last legs. I have to charge it daily and it never reaches a full charge unless I leave it attached to the battery while plugged into the outlet. I suspect the battery pack is fried, and with the 4.0 basically phased out, it’s hard to find a replacement battery pack.

I got the free 5.0 upgrade when I renewed my membership, but none of my old 4.0 bands works with it. I’ve seen those 3D printed adapters but they don’t appear to accommodate the fact that an attachment converter AND a different clasp is needed to make it work. So I pretty much don’t want to use the 5.0.

Any ideas on how to fix my 4.0 battery life, or make the 5.0 more compatible with 4.0 bands?
