LG has finally made its latest flagship smartphone official after a long wait. The G4 succeeds the G3 from last year and is claimed to bring a number of improvements across the board. However, unlike its predecessor last year, the G4 will have to face some really stiff competition. The strongest competition is of course Samsung’s latest flagship smartphone the Galaxy S6 and also its curved edge display sibling the Galaxy S6 Edge. To see if the latest LG flagship can take on Samsung’s best Galaxy smartphone yet, we decided to put these two smartphones head-to-head in a Samsung Galaxy S6 vs LG G4 specs battle.
Samsung had announced the Galaxy S6 at the Mobile World Congress in March and the two devices have gone on sale across all major markets around the world. It is the first Galaxy flagship smartphone to feature a truly premium build quality with no hint of plastic anywhere on the body.
LG had decided to skip the Mobile World Congress this year and delayed the launch of the G4. The smartphone will be going on sale in its home market of South Korea today onwards, but consumers in other markets will need to wait until May or even June to get their hands on the device.
If you have been following our Versus articles in the past, you will know that the LG G4 vs Samsung Galaaxy S6 specs battle will be divided into ten rounds. We will be comparing the performance of these two smartphones in a number of key areas such as the Display, Processor, Dimensions, Memory, Connectivity, Camera, Operating System, Design, Battery Life, and Price. Each round is worth one point, and the smartphone with the highest points at the end of the battle will be declared the winner of this comparison. Let’s begin.
When you go to a store to compare two new smartphones, the display is probably one of the first things that users look at and a great display is definitely going to catch your attention. Let’s see how the LG G4 and the Samsung Galaxy S6 compare against each other when it comes to the displays.
Last year’s LG G3 wasn’t the most impressive smartphone in the market in terms of the display. Despite boasting of Quad HD 1440 x 2560 resolution, the G3 display offered lower contrast compared to its rivals and a more muted color reproduction. This year, LG has decided to fix those complaints with the new Quantum IPS LCD display on the G4. It offers the same 5.5-inch size as the G3 and has the very same Quad HD resolution as well. The pixel density thus remains identical to the G3 at 538 PPI. Compared to the G3 display, LG claims the new Quantum LCD on the G4 offers 50% higher contrast, 30% higher brightness, and 20% wider color gamut. LG is claiming the G4 display covers the DCI color standard that is championed by top Hollywood studios. The display is protected with Gorilla Glass 4 on top, similar to other rival flagship smartphones launched this year. What’s more, the display is also curved slightly, although less so than the LG G Flex 2 display.
Samsung Galaxy S6 offers a slightly smaller 5.1” Quad HD Super AMOLED display with a pixel density of 577 PPI. It is in fact the most pixel dense display on a smartphone ever. Being a latest generation Super AMOLED display, the Galaxy S6 display offers much improved color accuracy over previous gen AMOLED displays. In fact, the Galaxy S6 display is one of the most color accurate displays on a smartphone currently, with only the Galaxy Note 4, Apple iPhone 6, and the iPhone 6 displays matching the Galaxy S6 display. Of course, if you want to enjoy vivid and punchy color reproduction, you can choose from the various available display modes in the Settings menu. The display is protected with Gorilla Glass 4, just like the G4.
So while the G4 offers a bigger display, the Galaxy S6 has a more color accurate Super AMOLED display with almost infinite contrast. So we’re declaring this round a tie.
When you’re spending top dollar for a flagship smartphone, you do expect nothing but the best in terms of performance. Unlike last year, 2015 flagship smartphones offer a greater jump in performance over their predecessors as Android flagship smartphones have finally started to arrive with 64-bit chipsets.
The LG G4 is powered by the Qualcomm Snapdragon 808 64-bit chipset that features six cores instead of eight on the Snapdragon 810. It has two Cortex-A57 cores and four Cortex-A53 cores. The dual-core Cortex-A57 cores are clocked at 1.8 GHz while the four Cortex-A53 cores are clocked at 1.4 GHz. Taking care of graphics is the Adreno 418 that is said to be 30% more powerful than the Adreno 330 GPU on the LG G3.
Samsung’s Galaxy S6 is powered by the company’s in-house developed Exynos 7420 64-bit chipset that comprises of four Cortex-A57 cores clocked at 2.1GHz and four Cortex-A53 cores clocked at 1.5 GHz. The GPU onboard is the Mali T760MP8 with higher clocks than earlier implementations of the GPU in devices such as the Exynos variant of the Galaxy Note 4. In terms of the benchmark performance, the Galaxy S6 definitely has a major edge over the G4 as it scores much higher in both CPU and GPU benchmarks.
Thanks to the significantly better performance, the Galaxy S6 wins this round.
Most people may not care much about dimensions of smartphones but it does make a difference. Two smartphones may have the same display size but could be quite different in terms of the physical size due to the difference in bezels.
The LG G4 is 148.9mm tall, 76.1mm wide, and 9.8mm thin. That is the maximum thickness though. At its thinnest point, the G4 is 6.3mm thin. It is slightly heavier than the G3, tipping the scales at 155 grams. In comparison, the Samsung Galaxy S6 is 143.4mm tall, 70.5mm wide, and 6.8mm thin. It is significantly lighter as well at 138 grams.
As you can see above, the Samsung Galaxy S6 is a lot thinner than the LG G4 and is also lighter. The dimensions round goes to the Samsung Galaxy S6.
The number of apps on the Google Play Store keeps on increasing every month and as smartphones become more powerful, the size of apps and games on the app store is also growing. Along with the space for apps and games, you also require space for your photos, music, and videos.
Samsung is offering the Galaxy S6 in three storage variants: 32, 64, and 128GB. There is no microSD card slot for memory expansion though. However, what makes up for the lack of expansion slot is the use of the new UFS 2.0 memory standard. UFS 2.0 memory offers significantly higher rear and write speeds when compared to the older eMMC 5.0 standard, as has been shown in various storage benchmarks. The Galaxy S6 internal storage is undoubtedly the fastest among all smartphones out there. Moving on to the RAM, the Galaxy S6 comes with LPDDR4 3GB RAM, offering significant speed improvements as well as power savings over the older LPDDR3 memory standard.
The LG G4 comes with 32GB of onboard storage which can be further expanded thanks to a microSD card slot. However, the onboard memory is of the older eMMC 5.0 variety, so it will definitely not be able to keep up with the Galaxy S6 in terms of read and write speeds. Since the Qualcomm Snapdragon 808 chipset on the G4 does not support LPDDR4 memory, the G4 comes with the same 3GB LPDDR3 memory as its predecessor.
Thanks to the faster UFS 2.0 memory, higher internal storage options, and LPDDR4 RAM, the memory round goes to the Samsung Galaxy S6.
Let’s see how the LG G4 and the Samsung Galaxy S6 compare against each other when it comes to connectivity features.
The LG G4 comes with LTE Cat.9, Wi-Fi 802.11a/b/g/n/ac dual-band, Wi-Fi Direct, DLNA, Wi-Fi hotspot, Bluetooth 4.1 Low Energy wit apt-X, A-GPS, GLONASS, NFC, built-in IR blaster, and microUSB 2.0 with SlimPort 4K. On the other hand, Samsung Galaxy S6 comes with LTE Cat.6, Wi-Fi 802.11 a/b/g/n/ac, dual-band, Wi-Fi Direct, hotspot, Bluetooth 4.1 Low Energy, NFC, infrared blaster, and microUSB 2.0
Clearly, the Samsung Galaxy S6 and the LG G4 are evenly matched in terms of connectivity. So the connectivity round ends up being a tie.
In the past two years, smartphone cameras have certainly evolved in terms of quality to a point where point and shoot cameras have become completely pointless. Both the LG G4 and the Samsung Galaxy S6 bring significant improvements in terms of camera over their predecessors. Let us see which one manages to win this round.
The LG G4 comes with a 16 MP primary camera and an 8MP secondary camera for video calls and selfies. Just like the G3 last year, LG is using a Sony Exmor RS camera sensor for the back camera. This time it is the Sony IMX234 sensor which is a 16MP 1/2.6” type sensor, paired with an f1.8 aperture lens that should allow more light to get into the sensor compared to its rivals. There is a two-tone dual-LED flash onboard, just like the G3. Optical Image Stabilization feature has been retained as well but this time LG has gone for a three-axis OIS implementation instead of two-axis OIS on the LG G3. The new three-axis OIS should allow the G4 to shoot steadier videos than the competition and also help it capture superior low-light shots, at least on paper. The G4 also includes a Color Spectrum Sensor at the back that analyzes the lighting conditions and accordingly adjusts the white balance and flash color to come up with an image that is close to real life in terms of the color accuracy and white balance. Another world’s first feature of the G4 is that its front-facing camera can also shoot in 4K resolution. The G4 is also one of the few smartphones to offer RAW image capture support and offers full manual controls in the camera app.
Samsung Galaxy S6 also uses a 16MP Sony Exmor RS sensor at the back. However, the sensor used on the Galaxy S6 carries a different model number – IMX240 instead of IMX234. The two sensors are identical in terms of resolution as well as sensor size though. Samsung has implemented its Smart OIS setup on the Galaxy S6 camera, which is actually a two-axis OIS implementation. The lens on the Galaxy S6 rear as well as front-facing cameras features an f1.9 aperture, allowing it perform better than previous Galaxy smartphones under low-light conditions. The flash is of the single-LED variety, so no dual-tone flash here. Samsung Galaxy S6’s rear camera can shoot 4K videos as 30 fps while its front-facing camera can shoot at Quad HD 1440p resolution. Based on all the reviews so far, the Galaxy S6 camera is the best on an Android smartphone yet. However, the LG G4 definitely has got all it takes to challenge the Galaxy S6 in this area. Preliminary reviews point to superior low-light performance over the Galaxy S6, while daylight shots should be more or less comparable.
Since the cameras on these South Korean flagship smartphones are quite similar to each other and the quality should be similar as well, this round ends up being a tie.
Both Samsung and LG have made some major changes with their custom Android skins this year for their latest flagship smartphones. Let’s see how the two compare.
The LG G4 runs Android 5.1 Lollipop out of the box with LG’s UX 4.0 user-interface layer running on top. LG has made its latest UX a lot lighter than before, and toned it down visually as well. As a result, LG’s custom Android skin doesn’t look too cartoonish anymore. A number of new features are also included with UX 4.0. The Quick Shot feature lets you take a picture almost instantly by just double tapping the rear key on the phone. This works even when the display is off. A new Gallery app is included too, with an emphasis on fast scrolling and Memories feature that automatically organizes your photos and videos based on the time and place they taken in. Smart Notice helps personalize notifications for weather, travel and more by analyzing user habits. The Quick help feature helps you find a quick answer to any question regarding the LG G4 functions and features.
Samsung Galaxy S6 comes with Android 5.0.2 Lollipop out of the box, with Samsung’s custom TouchWiz UX running on top. It has made some significant changes to TouchWiz this year, making it a lot lighter than previous versions of TouchWiz on devices such as the Galaxy S5 and the Galaxy Note 4. Like the G4, the updated UI is designed with Google’s Material Design guidelines in mind. All of the Lollipop features such as the ART runtime, lock screen notifications, multi-user support, Smart Lock, better battery statistics, and screen pinning are all there. Apart from these you also get a good amount of Samsung specific features such as S Health 4.0, Multi Windows multitasking, Ultra Power Saving Mode, Download Booster, Samsung Pay, Smart Manager, Themes, Quick Connect, and more.
Since both LG and Samsung have done a good job at tweaking their custom Android skins this year, this round will be a tie.
LG has decided to go with a completely different approach this year with its G4. While all other manufacturers have moved to using premium materials on their flagship smartphones, LG has decided to stick with polycarbonate. The LG G4 comes in two variants – one with a genuine leather back cover and one with a polycarbonate back that comes with a 3D diamond pattern. Apart from the different back, LG has made the body and the display slightly curved like on the G Flex 2 to make it more ergonomic in the hands. LG also claims the curvature increases durability of the smartphone slightly. Other than these changes, the design is very much reminiscent of the G3.
Samsung on the other hand, has done a more impressive job with the Galaxy S6 design and build quality. While the front is similar to the Galaxy S5, the back and the sides have been redesigned completely and look a lot more premium. The smartphones uses aircraft-grade aluminum and glass for its body, so no hint of polycarbonate on the Samsung flagship Galaxy smartphone anymore. While the Galaxy S5 couldn’t compare against the best built smartphones in the market, the Galaxy S6 can definitely go toe-to-toe with the most premium smartphones out there such as the Apple iPhone 6 and the HTC One M9. It is also significantly thinner than the LG G4 at 6.8mm. For greater durability, both the front and back panels are made of Corning Gorilla Glass 4.
Clearly, the Samsung Galaxy S6 is a more premium built device than the LG G4 and thus this round goes to the Samsung flagship.
Battery Life is a major concern for almost everyone as smartphones today offer much worse battery life than a few years back as they are a lot more powerful. Let’s see how the Galaxy S6 and the G4 perform in terms of battery life.
The LG G4 draws power from a 3,000mAh capacity Li-ion battery, which can be replaced by users as the back cover is removable. Even though the battery capacity hasn’t changed from the G3, LG is claiming the G4 offers superior battery life compared to its predecessor thanks to panel self-refresh and other optimizations that it has made. The G4 supports wireless charging with an optional dedicated cover but doesn’t offer quick-charging.
Samsung Galaxy S6 comes with a 2,550mAh capacity non-removable Li-ion battery. Unfortunately, the battery capacity has gone down when compared to its predecessor and as a result, the latest Samsung flagship offers lower battery life than the Galaxy S5. However, you do get the quick-charge feature which gives you about 4 hours of usage from just 15 minutes of charging. It includes support for wireless charging as well.
With a higher capacity battery, the LG G4 wins this round.
LG hasn’t yet announced the pricing information for the G4 but it is expected that the smartphone will be priced similar to the Samsung Galaxy S6 32GB variant. That means the G4 should be available starting at $199 on a 2-year contract from all the major US carriers. It is believed that the leather back variant may be more expensive but no details are available currently.
This rounds ends up as a tie since both smartphones are expected to carry the same starting price-tag.
We have finally reached the end of our LG G4 vs Samsung Galaxy S6 specs battle. Let’s start counting points and see which smartphone managed to come out on top in our comparison today.
We have had five rounds that ended as tie. The LG G4 and the Samsung Galaxy S6 are more or less equal when it comes to Display, Connectivity, Camera, Operating System, and Price.
LG G4 managed to score only 1 point. It has a significant edge over the Samsung Galaxy S6 only when it comes to the battery life thanks to the larger 3,000mAh capacity battery.
Samsung Galaxy S6 won a total of four rounds – Processor, Dimensions, Memory, and Design. The Samsung flagship managed to outmatch its rival thanks to a more powerful Exynos 7420 chipset, more compact dimensions and weight, faster UFS 2.0 memory with higher internal storage options, and a more premium design that uses more premium materials.
So, in our opinion, the Samsung Galaxy S6 is the batter smartphone of the two. Of course, you are entitled to your opinion, which is why we invite you to share your thoughts in the comments section below.
