Switching to 2G network is known to have noticable battery saving effect but since there isn't really any tools that checks if any tethering is enabled before switching network I decided to create my own Automate flow specifically for that purpose.
Feel free to use the flow as a base, the tethering checks can be safely removed as well if you don't need it (for 2G network switcher).
By default the delay has been set to 3 seconds, however you can legthen or shorten yourself based on your habits.
You can even remove the block completely but that will make the flow stuck in a no-delay infinite loop, which itself takes quite a bit of battery power and thus negates the power savings from switching to the 2G network.
WARNING: MADE TO WORK WITH DUAL SIM ONLY, PLEASE MODIFY THE FLOW ACCORDINGLY IF IT'S TO BE USED WITH ONE SIM CARD PHONES.
