You should use VoWifi right now
Using Vowifi to save some juice on android.
I was searching for ways to get extra juice out of my phone’s battery. One cool tip that I found was to use voice over WiFi if you are at the home, given the ISP supports it. Mine is Jio which do have it.
You can search on ‘Network & Internet’ -> ‘Mobile network’ -> ‘Sim’ -> ‘Wi-Fi Calling’ to find the feature.
Once it is enabled the phone will route any calls you do make or take using the lower power WiFi and reverts back to phone if WiFi is unavailable. Normally the phones use a lot of power when searching for a signal on cell network.
I haven’t tested this on many devices, but for my android it does work fine. Do try it
