Galaxy Watch 4 Suddenly Draining Battery

Great to have a remote instead of using the phone and draining battery even more throughout the day.

So far this battery has outperformed my Nikon batteries. It is exceptional. I never have to worry about it draining too soon.

Works fine, allows me to charge battery in camera, and to run camera without draining battery. Quite happy with this.

Running off a laptop means it helps to have an external that has its own power source so its not draining my laptop battery. I have a portable drive so I use this one when in the studio and both always contain the exact same files. I have used Western Digital for years and trust them as I have never had one fail.

This is exactly the cable I needed to allow me to use my Bose 700 NC headphones with my iPhone without draining my battery or needing an adapter. And the volume and play/pause buttons work perfectly so I still have the player control I wanted.

I bought this to use my 80D as a webcam for the Year of Zoom. Works perfectly and no worry about a battery draining while on a call.

Replaced the original battery that was draining badly after a year of heavy use. This is an original battery from Samsung, at half the manufacturer's price.

I reviewed this product on April 02,2018 about the issue with draining the battery. With my permission, the manufacturer contacted me and did investigation. It turned out it is the issue with the specific batch. Now the manufacturer has fixed the issue for me. The battery pack is now working like a charm. I appreciate the manufacturer’s excellent customer service. Thanks

Great that we have this AC adapter, this allows me to shoot and use the modeling light at the same time with no worries on draining my battery.

This is a great way to download photos to your phone without a computer and without draining your battery (phone and camera) by using the image transfer apps. All you need is an SD card reader and you will be able to transfer the images.
