iPhone 6S vs LG G4 Comparison

iPhone 6S vs LG G4 Comparison

One thing that I’ve learned from my years of reviewing iPhones is that people always want to know how other phones measure up to the iPhone. Everyone shows up to hate or to love, but they always show up. There’s a fact that people need to address. People care about the iPhone. Whether you hate it or you love it, you care about it.

I want people to address that fact because I want to be part of an Android community that loves Android more than they hate Apple.

Anyway, today we’re comparing the iPhone 6S and the LG G4. The LG G4 was the first phone to use Qualcomm’s flagship Snapdragon 808 processor, after LG was widely criticized for using the Snapdragon 810 in the G Flex 2.

I always say that it’s senseless to compare specs from two phones with different operating systems because each operating system requires different resources for different tasks; however, I hate comparing specs for anything. We can count cores and GHz and MP and mAh and display resolution all day. It’s still not going to mean anything.

iPhone 6S vs LG G4: Rear Camera

The camera on the iPhone 6S and the LG G4 are vastly different. LG took a very different direction with their rear camera this year.

LG went with the very common tagline of “it works like a DSLR”. Let’s make one thing very clear. It doesn’t work like a DSLR. You can’t change the lens. You can’t change the aperture. It does have some great manual controls, making it comparable to a good digital camera, but a DSLR is a step too far. It’s a comparison I hear a bit too much.

There’s a couple things I didn’t care for in the manual mode of the LG G4. One is that if the phone is in manual mode, all controls must be manual. In most phones with a manual mode, you can do things like manually controlling focus, while things like ISO and white balance can stay automatic. The other thing I didn’t care for is that the user can only take RAW photos in manual mode.

Apple took the direction that they always do, which is a great automatic mode. In fairness, this is how the vast majority of people use their smart phone camera. Most people want to be able to quickly launch the camera and quickly take a great picture.

While the LG G4 excels at manual mode, I felt like automatic mode was a downgrade from the LG G3. Autofocus is actually pretty bad, despite the laser focus on the back. It’s very rare that you find a smart phone camera that’s great in manual mode and still great when you pop it back into automatic mode. That’s why I started by saying that they’re two different cameras.

At the same time, the iPhone 6S doesn’t even have a manual mode. While autofocus isn’t great on the G4, it’s amazing on the iPhone 6S, as it tends to be with an iPhone. While LG uses laser focus, Apple, like Samsung, uses phase detection autofocus (PDAF).

There are a couple things I noticed here. The LG G4 has a larger sensor and a larger aperture, so it lets in more light. Unfortunately, I think that’s a drawback in really bright lighting conditions, as it seems to be too bright.

One thing I found odd was that the iPhone focused better at night. LG’s laser focus should work at night, in the fog, and any other place.

iPhone 6S vs LG G4: Front Camera

From all of my reviews of the LG G4, one thing that always impressed me is the front camera. The 8 MP front camera sensor is one of the best on the market.

Apple added a flash to the front camera in the iPhone 6S while also jacking the resolution up to 5 MP from 1.2 MP. Of course, they weren’t the first to light up the screen and call it a flash. The LG G4 does it as well, as does the LG G3.

There are a couple things to note here. First of all, all of the iPhone 6S photos are reversed. There’s a really odd reason for that. If I upload the front facing camera photos directly from the iPhone to here, the photos are upside down. I can edit them from within WordPress, but then when someone views the page from an iOS device, the photos look upside down to them. I open the files in Photoshop and save them as a different file, which fixes it. They still seem to be reversed.

The LG G4 has a larger field of view, which is important, as the group selfie is becoming more and more popular. The iPhone 6S looks better with the flash though.

iPhone 6S vs LG G4: Benchmarks

Here comes the same disclaimer as always. I hate benchmarks as they so rarely provide any insight into real world usage. They’re one tiny step above judging a phone based on specs. I use them anyway. Well, I publish the specs, which is worse than this.

First up is a battery test, which is the worst of the worst benchmarks. Always take battery tests with a grain of salt, mostly because all operating systems (also counting different Android skins as OSes) handle power differently when the phone is asleep.

First up is a battery test with the dim screen toggled off. Second is with the dim screen toggled, you guessed it, on.

The one thing we can take away from these tests is that neither phone seems to use much more power if the screen is brighter, which is pretty standard for an IPS LCD panel. As far as actual battery life, these tests are not true to life. I returned my iPhone 6S because the battery life was so bad.

Next up, Geekbench 3 tests.

I often hear the oh so ignorant question, “How can Apple’s dual core processors outperform our octa core beasts?” While the LG G4’s Snapdragon 808 is hexa core, the principle remains the same. They have more cores and more GHz, but they are certainly not beasts, especially when you realize that benchmarks don’t take into account software optimization nearly as much as you think, which is why they rarely provide insight into real world usage.

Next up, AnTuTu.

AnTuTu is more of an overall score and it also tests more of the GPU than Geekbench 3 does. The numbers here are accurate for an iPhone 6S and a Snapdragon 808. Nothing here is unexpected.

Next up, graphics tests.

iPhone 6S LG G4 GFX 3.1 2

Graphics tests have always been where the iPhone shines. This is because while the GPU continues to become more powerful, the display resolution remains the same. Well, the pixel density does, at least.

Just compare the numbers. The iPhone 6S’s display has about a million pixels. The LG G4’s display has almost four times as much. Can you tell the difference? Does the G4 look sharper? Well, no, not really. There’s a whole lot of disadvantage here and almost no advantages in a 1440p display.
