iPhone SE Battery

Hi, I recently bought an iPhone SE.

When I first got it I used it until there was 20% battery charge left, then charged it all the way to 100% and unplugged it.

I did that by the recommandation of a post here on the forum.

Now I get 5-6 hours of usage and over 18 hours of standby time, and still have 30% left.

I was wondering if this is good battery life for an iPhone SE?

Please let me know if you guys can! Thank you. 🙂

P.S. It charges SO fast, like in an hour it can charge from 30% to 90% and then trickle charges for another 45 minutes. Is this normal?
