Q: Then the LTE period is over can it be used as just WIFI
A: Yes, a Pixel Watch 4 with expired LTE service will still work perfectly fine, but it will function like the standard Wi-Fi model, relying on Bluetooth to stay connected to your phone for most features; you just lose the ability to make calls, get texts, or stream music independently when away from your phone. It will still tell time, run apps, track fitness, and use Google Assistant via your phone's connection.
Q: Does the Pixel monitor naps as well as sleep.
A: I think it depends on the duration. I've had it pick up a few naps that were in the 45min to 1 hour plus range, but miss some 'cat naps'. As far as regular sleep at night I find it to be pretty accurate.

Nice to be back with PixelWatch!
Coming from a Samsung Galaxy Watch Ultra. Wasn't a bad watch, but as a Pixel platform user (phone, buds) I really had to do a lot of research and hacking to get the health stats to work for me. I only went with it for the bigger clearer display, but the PW4 has done a great job of eliminating that as a factor. And since most of the hacks I used are soon to be obsolete, I felt it was time. So nice to be back where everything just works seamlessly. The new display is crisp and easy to read, even in bright sunlight. Very happy with the battery life and feature set and it's so much more comfortable to wear 24/7 (sleep metrics are important to me and the PW4 does a better job IMHO). The Best Buy experience was top notch (Bridgewater, NJ) and everyone at BB made the trade in and purchase experience wonderful from the moment I entered the store until I left. Watch was shipped NEXT DAY and arrived on time same day. Wouldn't go anywhere else!!

Couldn't be more happy
Couldn't be more happy with the Pixel Watch 4 which I've been wearing basically 24hrs daily. I needed an Android based watch since I recently switched to the Samsung Fold7 phone (phenomenal) from many many many years on Apple. Originally I tried the new Galaxy watch but it had inaccurate heart rates readings (I didn't know Samsung doesn't recommend it for those w/pacemakers) so I waited for the Pixel Watch 4 to arrive. I am getting a couple days of battery on the Pixel especially since I turned recently turned on the auto-on/off display. I tried the watch always on for a few weeks and have now switched to auto on/off display (thus the 2 day+ battery life) and it displays quickly when raising wrist. It charges super fast in the morning as I drink coffee. It recognizes when I am sleeping and waking up so I don't have to fiddle with that. Also decent for running but I haven't explored w/other activities like biking yet. My concerns are possible scratch-ability of the display so I am using the plastic film screen protectors which are holding up. Note the protectors that cover the whole watch have to be removed to charge so that doesn't fit the bill. SO VERY happy and STILL exploring Watch 4 features but no frustration and plan on keeping this for at least a year.

Almost perfect watch.
This is my 3rd smartwatch and my first from Google. The display is large and beautiful, but it scratches very easily, and after a week, I already have a noticeable one. I opted for LTE as a backup connection in case I lost or broke my phone while traveling. However, I learned that you can only store one eSIM profile, and I lost my free 2-year Google Fi data eSIM when I added a new eSIM. Overall, it's a good watch, but at the $500 price point, I wish it were more durable and allowed you to store at least a second eSIM profile, especially for traveling. It's a nice watch, and if they solved those issues or sold it at a lower price point while keeping them, it would be five stars. Pros: Nice large display. Two-day battery life. Easily customizable face. Cons: Can only store one eSIM profile Glass is easily scratched Gemini voice commands don't always work
