I have my E2 watches for few days now, and I could not notice system lags, even for few seconds! Also loading of apps, was horrible. And system response was just WOOOOOOOOF, I wanted to throw them away few times...
So I started searching and I found this post on Reddit
Since I do not mind to use Google Fit as default fitness app, and I am willing to download some app from G Play which will continuously read my hearth rate, then I decided to follow this guide.
What I personally disabled:
TicWatch Companion
TicSystem
TicHealth
TicExcersise
Mobvoi Privacy
Mobvoi Account
All credits go to u/dany_ev3 from Reddit, since I am just posting his post from Reddit here, to help more users.
Watches are now smoother than ever!
I hope this guide will help you

I'M NOT AN EXPERT, I DON'T KNOW IF DOING THIS CAN DAMAGE YOUR WATCH IN ANY WAY, SHAPE OR FORM, I DON'T KNOW IF THIS STOPS OTA UPDATES FROM COMING TO THE WATCH, I DON'T KNOW ANYTHING OR ANYONE, DO THIS AT YOUR OWN RISK, I DON'T TAKE ANY RESPONSABILITY FOR DAMAGE TO YOU, YOUR WATCH, PEOPLE AROUND YOU, DINOSAURS AND TALKING COWS THAT MAY BE EATING GRASS NEAR YOU.
ORIGINAL POST:
"So, I don't know if I'm the only one that had this problem, but my Ticwatch Pro was laggy as hell, barely usable, it frustrated me so much i stopped using it even while wearing it constantly. I had disabled every mobvoi app on my smartwatch and that improved battery life dramatically (Mobvoi account, Mobvoi privacy, TicExercise, TicHealth and so on) the only app i couldn't disable was TicSystem, I could only force stop it, and I had noticed that after stopping it my watch was smoother that it had ever been, but sadly it started again after a couple of minutes and the watch started lagging again, this may as well be caused by the TicSystem looking for all the apps i had disabled using all the cpu, but i couldn't give up the battery life I got disabling them, so I sat down and tried to find a solution.
And I did! I found a way to disable TicSystem via adb, and now my Ticwatch Pro runs perfectly smooth, this probably works on all ticwatch models but I haven't tried, and it's also extemely easy.
Before the tutorial I'll give you a disclaimer, I'M NOT AN EXPERT, I DON'T KNOW IF DOING THIS CAN DAMAGE YOUR WATCH IN ANY WAY, SHAPE OR FORM, I DON'T KNOW IF THIS STOPS OTA UPDATES FROM COMING TO THE WATCH, I DON'T KNOW ANYTHING OR ANYONE, DO THIS AT YOUR OWN RISK, I DON'T TAKE ANY RESPONSABILITY FOR DAMAGE TO YOU, YOUR WATCH, PEOPLE AROUND YOU, DINOSAURS AND TALKING COWS THAT MAY BE EATING GRASS NEAR YOU.
All jokes aside, I'm pretty sure it's fine, it probably will only improve your watch performance dramatically, but if something does happen to somebody, I don't want people blaming me, only do this if you know what you are doing.
So let's start, you'll need a computer, obviously, and your charging cable, you can also use adb over wifi if you are feeling extra fancy and don't want cables lying around, but I haven't tried that.
Go into your watch's settings, system, informations, and touch build number a bunch of times until it says you have become a developer.
Go back in your settings, developer options, and enable ADB debugging. (also enable wifi debug if you are doing this via wifi, but if you are doing it via wifi you probably know what you are doing so i'll just explain cable stuff from now on)
Plug your watch in your pc and allow debugging from that device (a popup will appear on the watch)
Install ADB on your pc if you haven't already, I won't tell you how to, it's full of guides out there, use google or your browser of choice.
Open your command line (cmd) and check if your watch is connected with adb devices
, if your watch shows up, congrats! you are basically done! Run adb shell pm disable-user --user 0 com.mobvoi.wear.system.aw and TicSystem will get disabled, you are now done!
If your watch doesn't show up in adb, google something like "adb device not showing up" and you'll find like a million tutorials.
If you ever want to enable TicSystem back, go in your settings, apps, app details, system apps (at the bottom), TicSystem, and tap "enable", wasn't so difficult, was it?
If someone else tries this, let me know your results! Very curious to know other people's opinions. Have fun, and be kind to eachother!
Edit: a user tried this and made me notice that his default ticwatch watchfaces disappeared, I think this only happens if you disable the "watchface" system app, if you want to keep them don't disable it, but keep in mind that if you disable the other ticwatch apps the steps counter inside the default watches will stop working because it's linked to ticwatch fitness apps, but google fit will still count your steps so it's just the default watchfaces that won't count steps.
Edit2: It's been over a day and the watch feels great, many people in all 3 subs (r/ticwatch, r/ticwatchofficial and r/wearos) gave feedback and said it helped a lot their watches too, i also tried on my father's ticwatch pro and i haven't noticed major problems, for now only the one described in the edit above, and a user made me notice that the ticwatch charging ui disappeared (doesn't bother me, didn't find it useful anyway) but if you want to replace it another user suggested "wear charging widget" on the playstore, he also said it works much better than the default one so there's that, I'll try to keep updating the post and answer everybody on all 3 subs, I'm extremely happy to see all those people enjoy their watches more and more thanks to me, you are all amazing!"
