Thoughts on my 16 Pro after 3 days of use (upgraded from a 13 Pro).
1. Battery life is great. I've only been charging to 85% just to try that out but it's easily lasting a full day of normal use. I had to charge some after a 2+ hour FaceTime when I started battery around 40%.
2. I haven't done a lot of tests yet but the video looks wonderful. I don't have any I can share (family in it), but it's ultra clear and looks great. The microphones are good and I've been enjoying the audio settings -- being able to change to Studio audio, for example, makes everyone sound like they are right in front of you, even if they are behind the camera. That's impressive.
3. I've been using the action button a lot set as a flashlight. I love the action button because I keep my phone on silent mode almost all the time.
4. The cell connectivity seems the same as my 13 Pro so it doesn't appear to have any noticeable antenna or other improvements in that area.
5. I appreciate how easy it is to transfer to a new phone. It took maybe an hour to transfer from phone to phone but it was mostly a directly copy of the device. I'm amazed at how straightforward the transfer was. I've done that before in the past, but it's so rare that I forget how smooth the process is.
6. I do miss the 3x zoom in some situations but the 5x helps me capture some things much better. I don't have images I can share yet (mostly family), but I'll do some more tests later this week.
7. I really like iOS 18. I know this isn't iPhone 16 specific, but it's a really solid update. There have been a couple camera bugs (viewing photo or video in the camera app instead of switching over to photos makes it look small), but it's possible the small update that I did to the OS this morning fixed that (Apple shipped with a slightly older build). I'm not sure because I haven't had the chance to see if it was fixed.
8. Low light photos are much improved over the 13 Pro. Again, no images to share (family photos so far), but a photo in low light with just light from a TV looked like it was fully bright like daylight with minimal noise. This is what I wanted in that case.
Sure, it's not life-changing in updates but I'm pleased with the 13 to 16 updates.
