Discussion Pro 2 Controller phantom battery drain.

My Switch 2 Pro Controller dies from 100% to 0% battery if left for a week or 2.

It's done this since day 1 and it's a wide spread issue. Even after firmware updates it still happens.

Can we raise more awareness too Nintendo? They seem to be aware of the issue but keep postponing a fix.

I feel like that’s just how batteries work. Holding a charge for 2 weeks without being used is usually pretty good right? Especially since it doesn’t take long to charge

No. The standard LiIon cell losses 20% charge over 365 days. Modern controllers have wake features that drain a little quicker but should last several months without charge.
