[Verizon LG G3] boe:
Thanks for the review. Now that I've had it a couple of days I thought I'd give my thoughts as well.

Battery life - at first I'd say it was comparable to my S4 but then I went to all applications and disabled a bunch that were on after I activated my phone - now the battery life is great - I've had it on but unused and uncharged since last night (1 push email account - no texting, no imdb, no calls) and it only went down 5% in 12 hours (BT enabled, WIFI disabled). The screen activity does seem to use more battery life than my S4 and so does GPS. Otherwise phone talk time seems to have about the same battery drain. I only use BT for making calls so BT is on 24x7. FYI I just got the Plantronics EDGE and it is amazing (I also have the Sennheiser presence which has better battery life but overall I like the Edge much more.

Charging - the phone is picky about chargers. I've used the same chargers I've had for years for my Nexus, S3, S4, Plantronics and Sennheiser headsets but the G3 said it wasn't acceptable and wouldn't use it to charge. On the plus side the included charger does seem to charge it quickly. Biggest disappointment - that it didn't come with a wireless charging backplate.

Signal strength - I'd say it has only slightly better voice signal reception than the S4 but every bit helps (e.g. calls from the cement garage beneath my apartment complex). Data seems a teeny bit slower though when running speedtest. I haven't done enough testing for this to be an accurate or detailed analysis.

Overlay - I have to say it seems zippy enough to me and as user friendly as the Samsung although different so it takes a teeny bit of getting used to - except the back arrow - that took a lot since it is on the opposite side from where my thumb automatically tried to go when I wanted to go back.

Screen - great size. I don't think the contrast is as sharp as the S4 - you can say it is color saturation or whatever you want - in the end it still means some things are as well separated. There is a color adjustment some say impacts contrast but what it does is adjust colors - not contrast IMHO.

Buttons - I thought I'd really freak out about not having the hard buttons where I had in the past but that was easier to get used to than the back button - I'm finally used to both though.

Bloat ware - both Samsung and LG have some apps I'd love to just uninstall but until you root them, you are stuck with the crap although most of it you can disable. Health was the very first thing I would uninstall if I could.

Issues - no issues so far other than the charging one. No reboots or hangs. My guess is that people are installing an app that doesn't play well with the G3 or perhaps the current version of Android. I admit I don't have more than 15 apps I install myself. The only ones I really care about are truecaller(mediocre call blocker/id app), Tesla (flashlight), call history, cal widget (calendar for home screen) and the rest are items I only use occasionally - e.g. ip calcs, where's my car, speedtest etc. I tried some live wallpapers and went back to static ones - attempting to keep every bit of battery life. I had a hard time pairing my BT headset with my new phone - perhaps there is something difference about the process on the G3 - I ended up using NFC and it worked instantly.

Conclusion - I like the phone a lot although I'm sure the S5 would have been an excellent choice as well. I like the screen size on this a bit more but I like the contrast on the Samsung screen. I notice the difference in large 4K TVs right away but for a screen of this size the S4 resolution was fine. You really have to look to notice the difference.
