[Nexus 5X Q&A, Help & Troubleshooting] adobeman:
Here are my data points.

>Does the battery life get you through a full day with at least 20% remaining? (this question is for people who don't game or game very lightly and mostly use texting, emailing with the occasional snapchat/instagram.) I'm a relatively light user and I have 40 or 50% left at end of day. I am quite happy with battery life. I use Velis Auto Brightness so my screen is pretty dim most of the time and only goes bright when needed. Using the USB type C charger that comes with it charges really fast too. Doze mode at night pretty much flat-lines battery use for me. Maybe a couple % all nite during doze.

>With Android N will the Nexus 5x see great or mediocre improvement in performance/battery life? (this might be more for the people who have been using all the developer previews) Not sure. Sorry

>One handed use, how comfortable is the phone to hold while browsing apps? I came from a Galaxy S3 so the 5X is a bit bigger but I have little trouble one-hand using the phone. But I typically wear XL gloves so my hands may be larger than yours.

>Is the screen legible enough when it is super bright out? It could be brighter but I do find it easier than the S3 outside.

>Is project Fi stable in your opinion?In my area yes. I am on 4G most of the time with Tmob. I have also seen the VPN Wi-Fi come on from time to time as well. I'd like it to come on more often.

>Should I wait until the next nexus phones are released?I was trying to do that but $249 for the 32g was so cheap I went for it. Known quantity with a great camera. Even when the new ones come out I'd wait a couple months for the real reviews to come in.

>What are any other options for a mostly pure android experience on other carriers?You can run the 5X on pretty much anyone. Verizon could be a pain but folks have done it. But.... I for my data usage I really prefer the pay for EXACTLY what you use model that Fi uses. Price per gig with the big carriers needs to be calculated as what you actually use per what you pay not what you could use per what you pay. So if that 6G plan costs $60 and you only use 3 your real price is $20/G., not the $10/G they make you think.

>Best rugged case for nexus 5xI really like this one https://www.amazon.com/gp/product/B015XA94OY/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1. Not sure if it's rugged enough for you. I actually prefer a little thinner case but this one grows on me more and more. The button covers are a little stiff. I use this tempered glass https://www.amazon.com/gp/product/B01C1TVYVQ/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

I tried the Adopted case that Google sells and hated it. It left a silicone feeling residue on my fingers and if I rubbed my eyes it was a disaster. Returned it.

I'm actually staying bone stock after many, many years of root/rom. It's weird seeing adds and not having Viper4Android but the ease of monthly updates and the [even if misplaced] sense of lower vulnerability is kind of nice. I never would have used any payment systems on a rooted/romed phone but Android pay is pretty handy. We'll see how long that lasts :) Since it's a Nexus there's none of that Knox crap or locked BL so if I decide to root/rom then should be no issues.
