Question S22 battery conundrum

[John Speed]

I only send a few of messages per day and usually the battery lasts 2 days max. Last year I went to Paxos (Greek island). The battery life jumped to 4 days ! On return to Uk it was back to 2 days. This year same again 2 days Uk but 4 days on Paxos. The same happened with my wife’s phone so it is not unique to my phone.
I have searched the internet but not found any clues as to why. Does anyone know what is causing this effect. Would love for 4 days in the Uk.

Welcome to Android Central! What's your cell signal like where you typically are in the UK? If your cell signal is mediocre at home, and if it was very good on Paxos, that might at least partially explain the difference.

Also, do you have any idea what your screen time was in both locations? Maybe you were using your phones less while on vacation (unless of course you were taking lots of photos or using them to navigate a lot).
