Best Running Watches For Battery Life

I have two of these running them in my A7iv. Best 3rd party battery I have found and I have tried a few. Slightly less battery life than a Sony and now with firmware updates we have the limitations Sony is putting on 3rd party batteries. You have spent $2500 on the camera body and a bunch more on lenses, is it worth the hassle to save $19 per battery. Seems silly and I would not buy 3rd party again just because it really doesn't make sense for $19.

We bought 3 watches as a family and could not have done better. Very satisfied, especially features, battery life and ease of operation.

This has been one of the best watches I have ever bought the features along with the battery life for smartwatch is amazing I highly recommend it for anybody who likes the outdoors or wants an all-around good watch

I can keep it running for hours. It is also extremely compact and light. Best battery ever had.

I have been running this camera for a couple months now, it’s been a workhorse! Battery life is amazing with the dual battery compartments! Having that extra battery life gives me the opportunity to stay out of my hunting spot longer to ensure I’m not leaving my scent everywhere or alerting deer I am in the area! Looks like I’m gonna need to pick me up a couple more for the fall! I am very pleased with the functionality of this new FLEX-PLUS camera!

Best phone I've had battery life excellent daughter said she has to have one for herself

Best sound ever in a snail package with awesome battery life

Best flashlight I've found for everyday use. Nice size and battery life.

Excellent long life. Best battery I have used. Beats Nikon, Canon, and Fuji.

Battery life lasts for several days worth of runs, super comfortable, no issues with slipping/rubbing on even long hot runs, love being able to hear around me and have conversations with running partners! Even great for answering phone calls that come in during a run. Love these so much, never going back to other running headphones!
