5.0 out of 5 stars Battery life like new
Reviewed in the United States on February 22, 2024
I'm aware that the Classic 4 came out in 2021 so by now the battery life should have noticeably started to degrade with it getting worse as the years go by and beyond. This being WearOS every % dropped per hour counts so you gotta optimize however you can and make sure the battery health is good. Despite this I am able to get nearly 29-31 hours on a full charge on Power Saving mode which is what I want, and it turns out this is around where others had their battery life back in 2021 according to some forums and other sites.
Cosmetic damage is somehow...under the watch? How did that happen? The screen and rotating bezel seem fine but it definitely took a beating on the under side. Doesn't matter to me so long as it functionally still works I guess and I don't see it.
Got a really sketchy charger with it though, so I had to go and buy another official one.
Thank you, the watch is nice. Would recommend even if renewed by Amazon.

5.0 out of 5 stars Awesome for the Price.
Reviewed in the United States on August 8, 2023
I like the crisp visuals, and the audio quality. I am disappointed in the battery life, but it is what you pay for. BPM, and O2 are very accurate and love the addition of a ECG. I do wish you could do more customization than what it has, but for the normal consumer it is great. It supports bands that are 20mm.

You can use a 20mm width band with:
Galaxy Watch5 Pro (45mm)
Galaxy Watch5 (44mm & 40mm)
Galaxy Watch4 Classic (42mm & 46 mm)
Galaxy Watch4 (40mm & 44mm)

4.0 out of 5 stars Battery life?
Reviewed in the United States on March 25, 2024
Good watch overall. Very happy with it. However the battery life runs out fast if you have bluetooth, wifi on, and alway on display. I find I have to have those things on in stints, only when I need it or it might not last a full 24 hours. Would love to see a version where the battery life sustains the usable features of the watch.

5.0 out of 5 stars Extremely pleased with this purchase!!
Reviewed in the United States on April 7, 2024
I was nervous buying a refurb product but this ended up being an excellent purchase. The watch looks brand new with no signs of wear or scratches. Plus, I waited a few weeks to write this review so I could throughly test the battery...which is rock solid!!

1.0 out of 5 stars Dead, lots of scratches
Reviewed in the United States on April 28, 2024
The bezel doesn't operate correctly, it's covered in scratches top and bottom, and is very dirty. Also arrived with a completely dead battery.

3.0 out of 5 stars Looks great, works well, bad battery life
Reviewed in the United States on January 18, 2024
I bought this to be able to listen to music while running, and it works great for that. But just doing that drains the battery pretty quickly. If I turn on location while playing music, it will drain half the battery during a 2 mile run. I ended up disabling everything (location, bluetooth) and putting it in battery saving to make it last around 3 days. I turn stuff on as I need it. With some 10 dollar fake leather bands, it looks great.
