Some devices taper off their fast charging faster than others. It doesn’t have to be at 80%. Just as an example you can see the charts in the charging review for the S24 Ultra here: https://www.chargerlab.com/charging-review-of-samsung-s24-ultra/. A fun fact is that since Samsung 45W tapers off so much there isn’t much difference compared to their 25W charging. The difference is 10mins at best. Sometimes the 45W can be just a hair slower even.

The 8 has a shitty optical sensor. You’ve gotta try those Samsung ultrasonic sensors or those on the Pixel 9s. Way different experience. Just a light tap and it unlocks.

I’m gonna have to say no to that. I love my ultrasonic sensor. It works when wet and is in a way more reachable location (the screen). No need to reach behind the phone or stretch your finger to unlock, no need to lift your phone when it’s on a table. The success rate is basically identical and it’s lightning fast, even faster than a physical sensor. The final perk is it doesn’t create a large circle opening on the back of a case so the back of your phone is totally smooth save for the camera.

Qualcomm settles and continues to pay ARM a bigger shitload of money, Qualcomm SoC prices increase to make up for that, phone prices increase further.
