LG G5 vs Apple iPhone 6s Plus



With the G5, LG introduced a thorough overhaul of its high-end line, eschewing plastic construction for a metal coating, and enhanced the novelty factor with a funky modular design that lets you add various attachments to the phone with ease. Add to these an intriguing dual camera unit, and the G5 is unlike anything we've seen from the company so far in its mainstream efforts. This is why we are pitting it against Apple's large-screen effort, the iPhone 6s Plus with its 3D Touch display.


The G5 modular design intrigue is jaded by the construction gaps in comparison with the solid unibody iPhone

The rounded corners of the LG G5 and iPhone 6s Plus emit a similar ergonomic vibe sitting side by side. That being said, the instantly recognizable iPhone 6s Plus is the larger of the two, so the G5 sits better in the palm and is easier to handle. Well, relatively, as both phones have pretty pathetic screen-to-body ratios, due to the large top and bottom bezels.

The iPhone's all-metal design is interrupted only by the antenna strips on the back, while LG uses a modular concept for the G5 design with a detachable bottom, making it feel flimsier when handled. The detachable half has its virtues, though, like the ability to swap out the battery that comes out with it, or add various media-centric and other accessories that LG calls Friends.

Both the G5 and iPhone 6s Plus have 360-degree fingerprint readers embedded in their physical home buttons, but Apple is using its signature round key at the front, while LG is housing said button on the back, which might present a challenge when you want to unlock the phone without picking it up first. These lock keys, as well as the volume buttons on the sides of the phones are easily clickable, with good tactile feedback, too.

Lacking in color credibility against the iPhone, the G5's display makes up for it in stellar outdoor visibility

The 5.3” LCD display at the G5's front has a higher pixel count – 1440 x 2560 vs 1080 x 1920 pixels - than the 5.5” iPhone, though for most practical purposes the screen density difference is quite negligible from a normal viewing distance. LG has provided a witty always-on feature that powers up a small section of the screen to display date, hour and pertinent notifications at all times if you are so inclined, though it would take a toll on the battery.

The iPhone 6s Plus has one clever trick up its display sleeve, too, namely its 3D Touch functionality, which allows the screen to detect various levels of physical pressure. This is used to enable new ways of interaction with the user interface – to peek into messages, to preview live photos, or access menus and modes within apps straight from the home screen by simply applying a little push on the screen. If our own polls are any indication, it's not something iPhone users are reaching for every day, but it may come handy at times.

LG almost compensates for the G5's colder-than-ideal color temperature with an extremely high peak brightness. We measured 816 nits, which is one of the highest numbers we've clocked so far on any phone. The iPhone also has very high brightness and low screen reflectance, yet the slight advantage outside under direct sunlight goes to the G5.


LG introduced a revamped user interface with the G5 and its latest Android 6.0 Marshmallow build, and now calls it UX 5.0 home screen. Gone are the cartoonish icon shapes and flashy colors, and the whole UI seems more polished and mature.

Besides the new coat of paint, LG has tinkered with the functionality, too. There is no app drawer by default, meaning all your apps will be plastered over your homescreen à la iOS. The Dual window split-screen multitasking has also been nixed, as we have a smaller screen real estate to work with now. The LG Health app has also been updated, and has received a visual and functional overhaul. Perhaps more importantly, however, G5 users will be treated to 100GB of free Google Drive storage for two years, which is neat.

Apple tends to strive for sense and simplicity when designing its products, and that applies to the iPhone UI experience as well. The iOS 9.x edition that is currently running on the iPhone 6s Plus is clean, streamlined, and easy to get the hang of. Besides, it serves as a gateway to a vast, quality-driven library of games and applications. The 3D Touch functionality of the screen adds a likable new level of app interaction, too.

Processor and memory

The processors ticking inside the LG G5 and the iPhone 6s Plus are vastly different in terms of architecture, so direct comparison would make no sense. Suffice it to say that both chipsets – the Snapdragon 820 in the G5, and the Apple A9 – are powerful and efficient. Moreover, neither of the two phones would have troubles running any of the latest apps and games.

With 4GB of RAM, the LG G5 should excel when it comes to multitasking in theory, and indeed you can line up tens of apps open in memory for whenever you might need them back quickly. The sheer RAM amount is not everything, though, as RAM management is at least as important, and the iPhone 6s Plus delivers on par with the G5, if not better, despite having less RAM to work with.

There are 32GB of storage inside the G5, plus support for a microSD card of up to 200GB, which, however, eschews Android's adoptable storage option, so the phone will always display the internal and added memory as separate entities. The iPhone 6s does not support expandable storage, as it comes with 16, 64, or 128 gigs on board, for a price. The advantage of the G5's approach is that microSD cards are less expensive per gigabyte, though not as fast or as reliable as embedded memory.

Browser and connectivity

LG went with Android's default Chrome browser on the G5, instead of its own concoction, and we can't blame it, as Google is making Chrome exceedingly faster and better. Apple's Safari browser, on the other hand, renders pages very quickly, too, and has a handy Reading mode that strips only the text from articles for easy skimming.

As for connectivity – well, the handsets are loaded with network compatibility and support for most Wi-Fi, Bluetooh, GPS or NFC wireless radio standards under the sun. When it comes to 4G LTE, though, the iPhone has the upper hand, as it flaunts a record 23 bands, letting you connect to local 4G networks almost everywhere you go with it.

For wired connectivity Apple uses its proprietary Lightning connector, while LG equipped the G5 with the trendy Type-C one, so now you have to remember to always bring the charging cable with you wherever you travel, as chances someone around you will have a Type-C cable are slim to none.


The Dual camera of the G5 intros wide-angle shooting, but has its tradeoffs in low light against the 6s Plus

On the G5, LG uses a unique dual camera setup that employs two lens modules – one with a 16 MP, and one with an 8 MP sensor, against the iPhone 6s Plus 12 MP cam with optical stabilization. Up front, we're still dealing with an 8-megapixel selfie snapper, while the iPhone employs a 5 MP shooter there.

The two units on the G5 are set apart by the dual LED flash in the middle, and the laser autofocus system. The main, 1/2.6” 16-megapixel camera has a typical 1.12μm pixel size, but wide, f/1.8 lens and optical stabilization—the same package available with the LG G4. The extra 8-megapixel unit, however, comes with extremely wide field of view – 135°, or more than that of the human eye.

The camera software of the phone lets you switch between the two sensors with a single tap, the idea being that you'd use the two cameras for different compositions. The secondary sensor allows you to capture scenes that you'd otherwise have to use the panorama option for. Being so wide, however, the lens don't deliver perfect stills, as there's a noticeable, fisheye-like distortion towards the edges, though not as strong as to make us hate this mode.

On the camera app side, the G5 sports a clean, outlined iconography, yet gives you a full manual mode, and funky regimes like Snap (Vine-like video capture mode where you can pause/start for up to a minute) and Popout (layers a shot from the main camera on top of a slightly transparent background from the wide-angled one). The iPhone sports a very neat and simple camera interface, too, covering all the basics like HDR or Panorama, and capturing the proverbial Live Photos animation with each shot seamlessly. Speaking of capturing, the 6s Plus is a bit faster to focus and take a snap.

When it comes to quality, we'd say that the phones are on par in good daylight. The G5 delivers very credible color presentation, which jibes well with what's really in front of the lens, while the iPhone goes slightly to the warmer side of the spectrum.

In low-light scenarios, the iPhone also delivered more uniform quality and less noise, while the G5 often produces hues that are too warm, or casts unpredictable color tones over the whole image, struggling with the proper white balance.

In terms of video, both phones can record 4K footage, as well as steady slow-motion ones, so in theory they are at the top of the mobile video game. The phones manage to record excellent clips in almost all situations, with good color presentation, but LG's software definitely inserts more digital noise in the frame. The imagery runs fairly steady, though not without frame skipping, which is more pronounced on the G5's footage. The phones managed to capture a great amount of detail, so not much to complain from on both devices when it comes to video footage.


The media apps on both phones do an equally fine job for basic tasks: browsing through photos, watching a video or playing music, but there are still contrasting points to be made for each. Тhe stock photo gallery on the G5 offers some quick editing options like cropping and basic effects, and that's about it. The built-in image editor in Apple's Photos, however, is more powerful, and does an excellent job at managing images. You also have Live Photos that are well integrated in the app.

For videos, LG's player has the upper hand when it comes to supported formats and extra features like adding subtitles, but Apple does more when it comes to editing, as usual. The iMovie app is an extremely capable video editor that handles multiple 4K videos without breaking a sweat, with effects, transitions, text and so on.

Then comes Apple's tune player that now integrates seamlessly with the Apple Music streaming service. This deep integration with the platform, huge catalog and great, curated playlists are definitely impressive. On the G5 you can get third-party apps like Spotify, which are also doing a great job, but they lack that deep dive within the system. The LG music player app auto-categorizes your songs, and has various equalizer presets that are accessible from within the app itself.

Call quality

Call volume with the G5 is very good on both ends, and people's voices are recognizable even if one were to blindly answer calls. On the downside, these voices sound a tad flat and robotic. Thankfully, the earpiece is large enough to ensure that even as you shuffle the G5's position relative to your ear, you're still getting good volume.

The iPhone 6s Plus delivers an acceptable performance through its earpiece, which happens to deliver reasonably loud tones. Voices come in a relatively natural and dynamic way, so we don't have complaints in this regard. The microphone does a similarly good job at transferring our voice to our callers, with a mostly clean and well-defined sound quality.


One day or two days of usage – this will be your G5 vs 6s Plus battery life dilemma

On paper, the LG G5 fails to impress, with a removable, but modest 2,800 mAh juicer. As with most other specs, battery capacity can be misleading, but that's not the case according to our custom battery life test. The G5 managed to keep it up for 5 hours and 51 minutes, which is pretty disappointing for today's standards, and means it will probably get you through the proverbial 24 hours of normal usage, but expect everyday charging to be a must. Thankfully, you can always carry a spare battery with you now.

The iPhone 6s Plus carries almost the same battery capacity – 2750 mAh – in a non-removable unit, but fares much better when it comes to battery life. We clocked north of 9 hours of screen-on time in our standardized battery benchmark test, so the phone will easily get you through a day and a half, or even two days with normal usage.

Where the G5 shines is charging time, as it tops up the exhausted juicer completely for about an hour and fifteen mintes only, while the iPhone 6s Plus needs more than two and a half hours to do it.

The LG G5 comes with a brand new modular chassis and a dual camera solution that amount to a unique phone amongst this season's flagships. It is smaller and easier to handle than the iPhone 6s Plus, though the craftsmanship leaves something to be desired in comparison.

If you have no use for the still-limited portfolio of extra LG Friends module attachments, though, the G5 doesn't offer something to really set it apart from the 6s Plus in terms of everyday usage like software performance or camera quality. The iPhone has one big basic advantage, however, and that is a much better battery life, which in real life often trumps added options that you may rarely use.

The basic 6s Plus is slightly more expensive than the LG G5, though, and offers less storage, plus it is big and a chore to handle and carry around in comparison. Thus, if you aren't sold on the superiority of its software ecosystem and stellar battery life, the G5 is one of the svelter flagship alternatives on the Android side of the fence, if you don't mind its faster value depreciation.
