Possible battery saving option for mobile phone.
The mobile signal (not WiFi) is a major user of battery power after the screen, the weaker the mobile signal the more your phone checks the signal resulting in more battery drain.
Something I tried and works for me, most modern phones have a setting called WiFi-Calling, this enables mobile calls via the internet if the mobile signal is weak and you have a wifi connection. This may have to be enabled so check first.
If this facility is available then select aircraft mode, this switches off mobile, wifi and bluetooth, you can then enable wifi and connect as usual.
You should now be able to make mobile calls via the wifi connection.
Reason aircraft mode allows reconnection of WiFi and Bluetooth but not mobile is because the latter is the strongest and could interfere with aircraft transmissions, apparently.
Try it and see, not sure how much battery it would save but the less you have to charge it the longer the battery will last.
