Battery on watch 7 drained within 10 hours

[user20Vo28pO0E]

The battery life on the Galaxy smartwatch 7 is horrible. It won't last much over a day so every morning I charge it to be sure it will last all day but yesterday, less than 10 hours after I had fully charged it, it was completely dead. Any way to extend the battery life?

What were you doing with it during those 10 hours? Calling, listening to media? Just normal use? Did it overheat at any time?  Have you run a diagnostic to see if the battery is good or has issues?  Dropping to 10 hours of use usually means the battery is faulty or you had extraordinary usage.  Normal use should get you 24-32 hours of up time.

Assuming the battery is good and you have not had abnormal usage, you can check to see if any of your apps have gone rogue and started running excessively in the background.  Pull up the app screen on the watch, tap the "open apps" icon (the overlapping orbs) and close all open apps.  Then clear the watch's cache partition. Other ways to conserve battery is to not use the AOD, use tap to wake rather than raise wrist to wake (if you use tap to wake, make sure you turn screen sensitivity off), lower the screen brightness.  Go to the Wear app watch settings and check the battery usage.  See what apps used the most battery.  If anything has used an excessive amount, tap on it and see if it brings up the stats window and check to see if you can turn off background activity (some apps you cannot, usually system apps)

I wasn't doing anything different than I do every day. I don't listen to music or use it for anything except checking how many steps I take each day, my heart rate, and reading an occasional text message. I don't know how to run a diagnostic on the battery. Can you explain how I should do that? Also, it doesn't look like any app uses much battery.

Your diagnostics can be found in the device care settings of your phone or watch or in the support tab of the members app (they all lead to the same place). Select diagnostics, select your watch and you can run diagnostics on the whole watch or just the battery.

Did this happen only once, or is the battery failing early several days in a row?  How long do you have the watch - is it still in the warranty period? If it is, you can get it evaluated at a uBreakiFix location, if you have one in your area or contact Samsung Service for options.

You can also put in an error report if the battery turns up with no problem. https://us.community.samsung.com/t5/Tips-Tricks/How-to-Send-Feedback/ba-p/3001692

I bought the watch April 12th of this year. The battery dying in less than a day only happened once, yesterday. All other days until I decided to just charge it first thing every morning it probably went close to 32 hours. I did a diagnostic on the battery and it says it's normal.

So. See if it happens with any regularity. It might have just been a freak incident. I get 32 hours out of my watch, but I like to charge it every morning anyway. The extra hours give me a nice cushion if I get side tracked and forget, or I'm traveling. Is it possible that the watch didn't get charged for some reason and it was running on fumes? I have my watch charger plugged into my computer and the other morning I put my watch on the charger without realizing a power outage shut my computer off overnight. It wasn't until I went to use the computer a couple of hours later I realized the computer was off and the watch hadn't been charging. You might have had a power interruption with your charger.

It might have been a fluke. I'm sure the watch was fully charged. I always plug it in when I take a shower in the morning and always check that it says it's 100% charged before taking it off the charger. It charges really fast but some mornings it's not quite at 100% when I'm done with a shower so I leave it charging.
