LG G6 rumor review: design, specs, features, everything we know so far

With 2016 on its way out, and the smartphone rumor mill in full swing as usual, it is time to take a good look at all the information we've got regarding next year's flagships, review it, and sort it out neatly for your reading pleasure and convenience. With the Galaxy S8/S8 Edge out of the way, it is now time to turn our attention toward LG and the successor to this year's modular G5. However, save for the seemingly universal assumption that it will continue LG's flagship naming scheme by moving on to the next digit, rumors regarding the LG G6 have thus far been as contradictory as they have been scarce.

With some reports suggesting that the LG G6 may ditch the modular concept of its predecessor in favor of a less-adventurous, waterproof design with non-removable battery, while others still claiming the battery will be removable despite the added water resistance, even educated guessing is becoming a bit difficult at this point. However, our job here is to present you with all the relevant information regarding next year's flagships, and that's what we are going to do now. With that said, let's take a look at all we know about the LG G6:

Samsung may be using Note 7 display tech for the Galaxy S8

Samsung is apparently planning to use the same space-saving display packaging technology that made a debut on the Note 7, with the upcoming Galaxy S8, tips Korean media. 

Dubbed Y-Octa, these displays have their touch sensors integrated in the panel, rather than layered like a thin film under the cover glass, and this also reduces the display controller size. All in all, it is a small amount of space being saved, but with today's tightly packed, extremely thin smartphones, every little bit helps. 

Does that mean that Samsung will also equip the Galaxy S8 with the other screen technologies from the Note 7, like HDR10-compliant display that can cover the DCI-P3 gamut? Hopefully, as there will be more and more HDR content to watch in the coming year or two, and the Galaxy S8 better be as futureproof as possible.

Black wallpaper on an AMOLED display: how much battery does it save?

A few weeks ago, we posted a selection of wallpapers ideal for AMOLED displays. The images in question had one thing in common – they were predominantly black – and that's not only because of the striking contrast achieved by screens of that type. It is a known fact that on AMOLED screens, pixels that are totally black draw no power at all. That is why putting a solid black wallpaper on such a display results in lower power consumption, thus improved device battery life. But at the end of the day, how much power would this save? Surprisingly, not as much as you'd expect.

The experiment

To test how much battery life I could gain by switching to a black wallpaper, I gathered three phones with AMOLED displays that I had access to – the Samsung Galaxy S7 edge, the OnePlus 3, and the Nexus 6P. Then I set their screen brightness to a constant level – 200 nits when displaying a white image. Normally, a smartphone screen's brightness fluctuates below and above that point (if auto brightness is enabled, of course), but 200 nits is a reasonable average. Finally, I ensured that no background apps were interfering with my experiment. 

My testing consisted of setting a series of 50 images as wallpapers and measuring what effect that had on power consumption. The average value of all 50 measurements served to show how much power each phone would draw with a typical wallpaper. Then I compared the figure against having a solid black image set as a wallpaper. I made a test using a solid white image as well, just to see what each phone's consumption would be in a worst-case scenario. Here's a chart with the results:

Now it is time to make sense of all that data, and I'll try to do that as plainly and simply as possible. Using the figures above, I can calculate how much each phone's power consumption drops if I switch to a pure black wallpaper. If I divide the result by the phone's battery capacity, I'll know how much battery I'd be saving. Okay, I'll stop with the mumbo jumbo now and give you some actual numbers:

• On the Galaxy S7 edge: savings of about 1.2% battery charge per hour spent on the home/lock screen or 3.2% at best (if you switch from a completely white to a solid black wallpaper).
• On the OnePlus 3: savings of about 0.6% battery charge per hour spent on the home/lock screen or 4.5% at best.
• On the Nexus 6P: savings of about 1.4% battery charge per hour spent on the home/lock screen or 4.6% at best.

Not a lot, huh? 

Conclusion

The power-saving potential of AMOLED displays is undeniable. It is one of the reasons why some power users go the extra mile and apply dark or black user interface themes to the AMOLED screens of their devices. It is why geeky phones like the OnePlus 3 have that option built right into their UIs. And it is also why some smartwatches use black extensively through out their menus to compensate for their tiny batteries.

But as our data shows, simply changing your phone's wallpaper to a black image doesn't have that much of an effect on battery life. Yes, you will gain a few more minutes of screen-on time. Perhaps you'll gain more if your device has a smaller than average battery or if you keep your screen set on high brightness all the time. But on a typical high-end handset packing an AMOLED display, the difference would be small, if noticeable at all. That's not only because the power savings are underwhelming, as we measured, but also because most of the time we spend with our phones is spent within an app or a game. 

So, are you surprised by the results? Have you experienced savings greater than what we measured? Or do you have any battery-saving tips to share? The comment section below is all yours!
