Smart Watches With The Best Battery Life

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

Would still like a camera and more battery life. Perhaps someday the watch band will become smart... Maybe an optional third party watch band with a battery and camera and strap connector acts as contacts to the watch...

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.

Brings new life to a Smart-UPS SMT750. It would have been nice to have had some warning that the battery was about to fail, but that's typical of a UPS that's not actively monitored. B&H came through with fast shipping

You've read the reviews - Poor battery-life. Well, if the camera is doing anything smart, it uses power. A spare battery doesn't cost that much, and works great, no matter how many shots the other battery did before it suddenly ran out of charge.

I’ve had my delta Pro smart extra battery about a month now. After using my Delta pro alone all summer I got concerned it would not have enough power to get me thru the night in the winter months on our off grid property. In summer with more daylight hours I would be down to mid 40’s percent battery life in the morning and that’s without using the propane furnace in my RV. After connecting the eco pro smart extra battery and using the furnace (since it’s getting colder at night in Kate September) I now have about 80% average battery life left in the morning. I charge using 6 240 watt solar panels which charge both units in a matter of a few hours. I have a firman remote start generator in case I have No solar during the day and it charges both units in a few hours as well. I’m looking forward to purchasing the EcoFlo smart generator next year and I will be set.

This is by far the best smart watch I've ever owned. The best feature is how the battery life of this watch is measured in weeks/months and not hours/days. Notifications just work, the GPS is awesome, and his watch is thankfully not something I have to think about because it just works.
