So what is the next phone going to be? Maybe nothing? Or a simple and very cheap feature phone with a battery life of several weeks?

I've been forced to start using smart phones for all of my phone stuff and must say I'm quite surprised with how well my Xperia X does with battery life. But yes, of course, I should give it a few months and then see whether it's still OK.

When I signed up for a mobile account here in Canada the manager said that his Motorola battery life was really great. Have you tried out the Moto yet? Not sure which model he has. Could be the latest one.

I agree with you about Apple. Haven't used Xiaomi but the last phone with great battery life for me was Nokia 1100 But then it's not smart.

If you find a smart phone with longer battery life please let me know. It's one of my top requirements for a phone. My Samsung Galaxy S7 battery is slow in comparison with the Xperia. I'm going to watch how the Xperia behaves with battery and see if there's something better out there.
