TL;DR 1.5 m cable, instead of 1 m. Color-matched and braided.
There’s no way an 8 inch cable works for you. 8 inches wouldn’t even span the distance from my car charger to a phone clamp or from my computer to my desk.
3 ft is barely tolerable for me. 6 feet gives me enough room to move my phone around.
8 would work for my desk, my car, my bed and the one that sits on my counter. 3ft is too much cord and I end up with a lot hanging. 6ft is definitely too much.
Then again I don’t use anything when it’s charging, so my use case is out of the norm
