FYI - - As I mentioned, the battery in my iPhone 8 went downhill fast on this trip. It's about 3 years old. I got a cheapo kit on Amazon to replace it myself...and the battery is great!

Unfortunately I killed the home button, front camera, and microphone in the process!! Barely functional until I get a new one (iPhone 12 on the way).

I lost $90 in trade-in and $20 for the battery. I could have just paid a pro $65 to do it right. Lesson learned.
