I still have a few items to close the loop on.
Battery Life - My iPhone's battery life is really incredible. I tend to check the battery at 10PM. Most days the % of battery remaining is around 60%. If I've taken a lot of video or listened to a lot of podcasts, it will dip down into the 50% range. I checked the battery capacity recently and it is still 86%.
Face ID - I mentioned that the face unlock of my Lenovo Tab M8 inspired me to look at the iPhone X's Face ID. That was before the COVID-19 pandemic drove facemask usage. Now I miss the Touch ID of the iPhone 6.
Gboard - I am a huge user of Google services. Consequently, I tend to use the Gboard keyboard. But Apple has crippled Gboard. I like to use handsfree voice to text while I'm driving. When using Gboard's voice to text, Gboard has to launch what looks like a separate app. The delay is unacceptable. And the Apple keyboard's voice to text is really good.
Wireless Charging - I've had a couple of Android phones that used wireless charging but the Essential PH-1 didn't. It was nice to return to wireless charging. This is the wireless charger I use. I use this for my wife's iPhone SE (2020).
Old Stuff - I still wish iOS would give me more control over sounds, e.g. Google Hangouts ringtone and texttone, the camera shutter sound, the iMessage sent sound, etc. I do really like the intensity of the vibration. The Essential PH-1 struggled with being too subtle.
But I do still have an Essential PH-1 completely up to speed on Lineage OS.
