just wanted to share my experience with the OnePlus Nord Buds 3 Pro after using them pretty extensively for like 20 Days
I started using them at 100% battery around 9:44 AM, and by 1:20 PM, they were down to 30%. During that time, I had:
- High noise cancellation (ANC) turned on
- Volume at 100% the whole time
- Constantly playing music via Spotify
- Connected to two devices at once — my phone and my laptop
So yeah, I was basically using every power-hungry feature possible.
Under those conditions, I got about 4 hours and 36 minutes of usage with 70% battery drained. That means with a full charge, they’d last me around 6 hours and 10 minutes max when used like this.
Now, I’ve seen people say these can last up to 8 hours, but that’s definitely not happening if you’re running them on full volume with ANC on and dual-device pairing. Those numbers are only realistic if you:
- Turn off ANC
- Lower the volume
- Stay connected to just one device
- And don’t stream constantly
In real-world heavy use (like mine), you’re looking at around 6–6.5 hours, maybe pushing close to 7 if you’re lucky. But 8 hours? Not with max settings — that’s marketing talk.
Overall, I’d say the battery life is actually pretty solid, considering how hard I was pushing them. They’re performing within expectations. But yeah, if I ever need longer battery life, I’ll have to lower the volume or turn off ANC.
Just figured I’d share in case you were wondering to buy this and how they hold up with everything turned on.
