We will leave our remote plugged in for DAYS and it just won't charge past 10% or so. I've tried different power adapters and cables. It's only a couple years old, what's the deal? Anyone else have this issue? I might look into replacing the rechargeable battery if it's cheap enough, but otherwise I'll just replace it. Seems silly that their "Pro" remote only lasted a year or two.
I just ran into the same problem, but I finally found something that worked (see this Roku community comment).
Here's what I did:
My remote would not charge above 11% even after trying 10 different cables / adapters / outlets, resetting the remote, etc. But it's only been 2 years - not enough for the battery to "die" as Roku suggests (what's the point of an environmentally friendly rechargeable remote that you have to toss and replace every 2 years?). Now - it is charging just fine (already at 60% after just an hour).
I don't know why this worked, but seems a little odd to me. Feels like a software issue. Almost as if the Roku software is programmed to assume the battery degrades over time. Not sure why else "resetting" the battery would cause it to suddenly worked. The battery plug was tightly in the socket before I took it out, so I don't think it is about "loose connections" developing over time.
In any case - this is the one thing that finally worked for me.
I had the same problem and just found a fix that worked. I was so frustrated by it I'm now replying to similar questions in this forum with a solution 🙂
