[Magisk] 73sydney:
Mine goes on the wireless charger about every 2nd day, i dont track my location etc.

Step 1 - Dont buy the small one:

Buy the 44m Watch 4, or the 46mm Watch 4 Classic. Dont find out the hard way the 40mm one is a dire POS. lady friend of mine as getting barely 8 hours out her 40mm one, after she turned stuff off...

Step 2 - Resident Bloatware:

Consider removing resident bloatware if you dont use it

adb shell pm disable-user --user 0 com.microsoft.office.outlook

adb shell pm disable-user --user 0 com.samsung.android.bixby.agent

adb shell pm disable-user --user 0 com.samsung.android.bixby.wakeup

Step 3 - Google Assistant:

If adding Google Assistant, once you have set it up turn off Hey Google for it

Settings -> Google -> Assistant -> Hey Google (toggle off)

and instead assign it to a button for on demand use instead (Settings -> Advanced Features -> Customize Keys and assign to a key, OR use one of the following depending on your case if you prefer to use the stock accessible buttons for other remaps - i use double home for Wallet for example (and yes currently theres a bug where double back will forget the association randomly):

Step 4 - Connection Settings (Settings -> Connection):

- NFC (toggle off - you can toggle from the NFC tile (add if needed - cant remember if added by default) on notification pull down...i enable NFC only when i need to pay for something, then straight back off again

If not using eSIM plan:

Mobile Plans (toggle to Always Off)

Scroll down to Looking for this and tap Location, and toggle off (as with NFC i toggle is via notification tile as needed. Note: i also never track my walks)

While in Location you can tap Permissions and set location permissions for apps (you can all also do this in the very granular overall Permissions menu)

Step 5 - Display Settings (Settings -> Display):

Turn off Auto Brightness and Gestures.....

- Auto Brightness (toggle off, then tap on brightness circle above and set at a reasonable level)

Below that:

- Always On Display (toggle off)

- Raise Wrist To Wake (toggle off)

- Touch Screen to Wake (toggle on - its nice to have a way that doesnt wear your button out)

Optional: Scroll to bottom and toggle Show Charging Info off

IMPORTANT: Always turn off ADB Debugging OFF you turn it on to do any ADB work...it will drain the battery like nothing else....

Optional tasks:

Consider Disabling Workout Detection

I disable Automatic Workout Detection (Settings -> Samsung Heatlh > Activities To Detect - toggle off) and instead have a Walk shortcut on my launcher thanks to Pixel Minimal watchface (ultimately most people will find this is the best there is, plenty buy or get coupon (free) watchfaces, but the sane folk (the rest of you) end up where i started as a madman) - next to that i have the Steps (counter), then my Heart Rate. This works for me as i only ever walk for exercise (bonus info havent run since i was 18, fractured both legs in the spin up to Gulf War 1 - i was 2 weeks from going, ended my career - never fired a shot in anger)

Wipe Cache (occasionally)

For lag, most useful after an update

Samsung Health Monitor (Mod)

If rooted or in an unsupported area for Samsung Health Monitor, give @Dante63 a visit for his mod of it,

https://xdaforums.com/t/restriction...ce-restriction-removed-25th-oct-2022.4322527/

Never seen a dev develop apps to make installing and maintaining their mods possible/easier like does...

Also just about the nicest person on XDA, and Reddit, and Telegram and im sure somewhere else he has turned up to prove this - has left me actual voice messages when he was doing his best to try and coax my lazy ass into doing some work to reverse Samsung Health (different to his Samsung Health Monitor) despite him having way more knowledge of Android under the skin, and me always luckily finding alternate methods that required much less work :) A very selfless, helpful and determined person is Dante....
