Review on 💦 Waterproof Smart Watch and Fitness Tracker for Android and iOS Phones with Heart Rate & Blood Pressure Monitor, Sleep Monitor, Information Reminder, Step Counter - Ideal for Women and Men's Health and Wellness by Kyle Ross

I'm not sure about the battery life. When I received the item and opened/turned it on for the first time, it showed a battery life of 75%. I charged the watch and downloaded the app. After connecting the watch to the app, the battery life shows as 100% fully charged. I wore the watch for 16 hours and the battery life is 13%. Then I took off the watch, charged it for 2 hours and went back to check it out. it was 100% charged. I then unplugged it and fiddled with the settings by changing the background screen (in the phone app, not the watch). All of this was within 10 minutes or less of the time frame. Then I turned on the watch to make sure the screen switched to the selected image, which it did. but the battery life dropped to 42%. I have to see if there are any other problems.
