Hey all, bit of an update.
I decided to treat myself to a new iphone instead of trying to replace the battery.
I may replace the batter in the SE anyway and keep as a second phone.
At first I wanted the iPhone 13 - 256, it seemed the sweet spot for me in terms price and features. But I soon realized that size phone wouldn't work with my motorcycle and where I would store it. Took at second look at the 13 mini and it was the perfect size, and the price was better.
It's a nice update, the screen is great, it's quick, and finally a battery which lasts almost the entire day and doesn't die when using certain apps.
Though I do miss having a actual button. I think the UI experience was better with the button, it was faster and there is none of this weirdness with the UI doing something different then you intended. I've had the home screen customize interface appear so many times when I just wanted to open the phone to look at something.
We'll have to see how this phone holds up in the colder weather those, for now it's good.
