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 (type cmd in the windows start bar, this also works on mac, but you have to edit the commands a little, look up an ADB mac tutorial) and check if your watch is connected with:
adb shell pm disable-user --user 0 com.mobvoi.wear.system.aw
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/WearOS, r/TicWatch, and r/TicwatchOfficial) 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 any problems, but 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!
Edit3: It's been 12 days since I disabled TicSystem on my watch, and in the meantime I also disabled all the tic apps on another Ticwatch Pro and a Ticwatch S and they are all working great, I haven't found any problems at all, and many people reported imporved performance on every Ticwatch model! No other problems were reported so I'll go ahead and say this is probably going to be the last update, I may make a short video tutorial on youtube if people on XDA request it. For now, I'm extremely happy I got to help so many people and that everybody found new life in their old watches! I hope you all keep being amazing and I want to thank you all for a last time for the awards, all the support and all the kind words I got, have a great day!
