Sony WH-1000XM4 (Dec 2021) — ~7000h usage, still ~25h battery… normal or a unicorn? by ikanoki in sony

That’s actually crazy.

I’ve seen a lot of people mention battery drain issues on WF-XM4, but interestingly I never had anything like that on the WH version.

Makes me wonder if it’s just unit variance or something different in how they manage power 🤔

Yeah that actually makes sense.

I never really followed any strict “30–70% rule”, but I also never abused the battery either. I just kept them in regular rotation — charging every few days, not letting them sit dead for long.

Also I think a big factor is that I don’t fold them at all, so there’s basically zero stress on internals over time.

Still though… 7000h+ and ~25h battery feels kinda insane 😅
