Battery life on the Sony WH-1000XM6 is excellent. You get 30 hours with noise cancellation on, or 40 hours if you turn ANC off. That's enough for multiple transcontinental flights before needing a charge.
The quick charge is genuinely useful:
Forgot to charge before your flight? Plug them in for 3 minutes with a USB-C PD charger and you'll get 3 hours of playback. That's enough for most domestic flights from a 3-minute charge.
With a regular USB charger, 3 minutes still gets you about an hour of listening time.
A full charge takes 3.5 hours, which sounds long but you'll rarely need to go from completely dead to full. Most people just top off overnight.
New feature: listen while charging
This is something the XM5 couldn't do. If you're on a long trip and your battery is dying, just plug in and keep listening. The battery charges to about 80% while you're using them. Useful when you're stuck at an airport with a long layover.
Comparison:
The XM6 beats the Bose QC Ultra (24 hours) and AirPods Max (20 hours) comfortably. If battery is your absolute priority, the Sennheiser Momentum 4 wins with 60 hours, but it doesn't match the XM6's noise cancellation or features.
Battery indicator:
The Sony Sound Connect app shows exact percentage. The headphones announce battery level when you turn them on.
The 30-hour rating is accurate for normal use. Check current prices on the Sony WH-1000XM6.
