Legend! My watch battery was dropping 11% every hour on power saving mode. I followed these instructions and now it's still on 100% an hour after taking it off charge. Thank you so much!

Okay so I did this method exactly 7 days ago as I'm typing this comment (I actually made a reminder on my watch to comment my 7-day observations after this method) and I didn't expect this to work, but it freakin' worked!!
It did solve the visible laggy-ness and stutters of the whole UI and my favorite part is that I really did notice a significant battery life improvement! Yes. I am not even joking. Well, at least it worked for me.

And before I did this method, my Watch4's battery was draining so damn quickly, like I can only get 6-hours of it at home (with wifi=on, location=on, AOD=off, raise to wake=on, auto-brightness=on, power-saving=off)
I also have the water and sedentary reminders on, so I actually use it and press buttons from time to time and I also use the Timer very often for house chores and whenever I cook.
I also do 5-minute push-ups daily so yeah, there goes some sensors workin' hard as well.

Where now, I charge it at 11PM and still have like 86% left the next day around 12NN. Yes, same settings as what I stated above and same daily routines. Didn't change a thing in my day to day.

It's actually unbelievable you know. Who would know clearing cache would improve the battery life!?

So thank you so much, @WorldofTech 🙇‍♂You earned a Like! 👍👍 You are a Legend

Edit: I also Bixby btw. So yeah, whenever I raise my wrist, I talk to Bixby like most of the time to set timers, reminders, and control my light.

Thank you! My watch just started gobbling up battery over the past two days. I followed these steps and my watch is back to normal. Thanks again

Thank you for this.

My Watch 4 was losing battery like crazy, but following your instructions saved me from binning it.

Perfect tutorial! Why can't other videos be this simple and to the point? Much appreciated! liked and subscribed ✌️

Thanks!
I got my Watch 4 today and was super disappointed because of the amount of lag it had.
But after going through what you demonstrated, its doing so much better now.

Perfect. Thank you. For anyone wondering if this still works, YES it does. I'm on OneUI 5 with WearOS 4.0 Mar'24 Security Patch. You have to follow the instructions in this video perfectly to get to the bootloader menu. You let go of both buttons when you see 'Rebooting' under Samsung logo and and as soon as the screen goes blank, press the power button as shown in the video.

Thank you! Easy to follow tutorial, I hope it helps with the sudden draining battery issue.

I really didn't expect it to work, but it helped a lot for my battery life.

I have a two year old Galaxy Watch 4 that has been through a few updates, including a major WearOS one. After a recent update, the battery life has become absurdly disappointing, barely achieving one day.

After clearing the cache, I can do two days, just as I could originally. Do it guys, it helps.

Thanks! Plain and simple and right to the point. :)

[sunsetraving]

Thank you sooo much!!! Such a straight forward and easy how to.

[beckyb]

I hope this works, thank you! Very easy to follow! After the last update my battery is not even lasting 12 hours when it used to last 2 days!!!
Will see how it does once charged.

Thanks for the video. I have had my Watch 5 for almost 2 years and noticed lately that it is getting a little slow when I am making different selections.
