LG G5 vs G4: What's new in LG's flagship phone?



LG G5 vs LG G4: What's new in LG's latest flagship device?

The LG G5 release is imminent, and LG's device is shaping up to be one of the most exciting smartphones of 2016. But how does it compare to the outgoing LG G4?

Many people were a little underwhelmed with last year's LG G4, which was largely an iterative update over the LG G3 before it. Fortunately, there's a lot more to get excited about with the G5.

This time around there's a completely fresh design, much more power, some new biometric tricks, and a couple of surprises that you won't have seen in a phone before.

So, what exactly has changed? Let's take a look.

Watch our LG G5 hands-on video

LG G5 vs LG G4: Design

LG G5: 7.7mm thick, 159g, all-metal build, modular design, fingerprint sensor

LG G4: 9.8mm thick, 155g, curved design, plastic edge, removable back with choice of materials, rear button

The LG G5 looks completely different to the LG G4. Given the that G4 looked a lot like the G3, and that the G3 followed on organically from the G2, this is the biggest design overhaul yet for the range.

The LG G5 packs an all-metal design, a big improvement over the plastic feeling G4. Yet it doesn't feel like any other metal phone we've ever held. It feels hollow, somehow, and even a little - dare we say - plasticky.

Also, the switch to metal means the loss of the LG G4's leather back. Whether or not that's a good thing is a matter of personal preference.

While the LG G4 has a traditional removable back cover, the LG G5 has a modular design that sees the battery slotting into an accessory slot on the bottom of the phone.

This modular design really is one of the standout features of the LG G5. You can slide out the basic panel and replace it with others to add extra functionality.

B&O has teamed up with LG to release a DAC that'll give you an extra headphone port capable of playing 32-bit audio and there's a camera grip that adds in a physical shutter button and a beefed up battery.

LG is opening up this modular design to others too, so we'll hopefully see a wealth of unique accessories over the coming months.

A little unusually for a 2015 flagship phone, the LG G4 didn't feature fingerprint-sensing technology. However, the company's late-2015 high-end release, the LG V10 did.

That's changed with the LG G5 though, which implements such biometric technology. The power button is still on the back, but it now features a fingerprint sensor built-in. From our initial impressions it seems this is one fast sensor, so that's a bonus.

Interestingly, reports from the middle of last year suggested that LG was investigating iris-scanning technology for the LG G5. However this hasn't come about.

Either way, the LG G5 is certain to be a whole lot more biometrically endowed than the LG G4.

LG G5 vs LG G4: Display

LG G5: 5.3-inch, 2,560 x 1,440 IPS Quantum display, 554 ppi, 900 nits brightness, always-on

LG G4: 5.5-inch, 2,560 x 1,440 IPS Quantum display, 538 ppi, 454 nits brightness

LG has stuck with a 5.5-inch quad-HD display for its last two flagship phones, the LG G3 and LG G4. But that's all changed this time around, the G5 sports a slightly smaller 5.3-inch display

It still keeps the same resolution though, so the pixels are a little closer together.

LG has kitted the G5 out with a nifty always-on display that'll keep you updated of the time without you needing to switch the screen on. It's a better system than the equivalent Samsung Galaxy S7 offering, with more notifications catered for.


However, the fact that this is an LCD display rather than AMOLED means that the LG G5's screen will always be slightly lit up, which is a little irritating in a dark room.

The G5's screen also packs double the brightness of the G4, at a whopping 900 nits. You will rarely, if ever, need to push it this high, but it could come in handy for sunny days.

LG G5 vs LG G4: Performance

LG G5: Quad-core Qualcomm Snapdragon 820 chipset - dual-core 2.15 GHz Kryo & dual-core 1.6 GHz Kryo, Adreno 530 GPU, 4GB RAM

LG G4: Hexa-core Qualcomm Snapdragon 808 chipset - 1.8GHz dual-core & 1.44GHz quad-core, Adreno 418 GPU, 3GB RAM

One spec we were certain of even before the official announcement was that the LG G5 would run on Qualcomm's Snapdragon 820 CPU. And it does. This makes it significantly faster than the LG G4 and its Snapdragon 808, which wasn't even the fastest Qualcomm chip of last year.

How much faster are we talking here? Well, Qualcomm reckons that the Snapdragon 820 is 40 percent faster than its predecessor the Snapdragon 810, which is a quicker version of the Snapdragon 808 in the LG G4.

So, quite a bit faster then.

LG has also stuck an extra gig of RAM in the G5, taking it from 3GB to 4GB.

On the internal storage front, both phones have a microSD slot and start out with 32GB of internal storage.

LG G5 vs LG G4: Camera

LG G5: 16-megapixel & 8-megapixel, f/1.8 & f/2.4 lens, OIS, laser autofocus

LG G4: 16-megapixel, 1/2.6 sensor, f/1.8 lens, OIS, Colour spectrum sensor

Some smartphone manufacturers (not Samsung) seem to be slipping back into the habit of cramming more pixels into those tiny image sensors. However, they're getting savvier with their implementation by the year, so it isn't necessarily a bad thing.

The LG G4's 16-megapixel camera was one of the finest of 2015, and the LG G5 easily matches that. It's still a 16MP sensor, but it's now joined by a secondary 8MP 135 degree camera for taking wide angle shots. You can quickly switch modes and the results look pretty awesome in our tests so far.


We're a little concerned over the drop-off in capabilities of the laser autofocus system in low-light, but there's always a chance that LG will provide a software update for launch.

Both the G4 and G5 have 8MP front-facing cameras, and it doesn't look like anything changed this time around.

LG G5 vs LG G4: Battery

LG G5: 2,800 mAh

LG G4: 3,000 mAh

Interestingly, the G4 has a slightly bigger battery than the G5 - 3,000 mAh as opposed to 2,800 mAh. We'll have to really test out the G5 before we can see for sure whether this makes a difference, but it seems to be a step in the wrong direction.

Still, our initial impressions of the G5's battery life have been good. It can get through a full day of high usage with 10 percent remaining in the tank. Given that battery performance in the G4 was nothing to write home about, we're willing to call it a draw at this early point.

One bonus for the G5 is that LG has switched over to USB-C 3.0, which gives it even faster charging. But, you'll have to ditch all your old cables, which is a bit of a bummer.


Early Verdict

LG deserves credit for radically overhauling last year's flagship phone. As much as we love the Galaxy S7 and the iPhone 6S, their designs are barely changed from their predecessors.

Not so with the G5, which has a smooth all-metal look, a more compact display, a unique modular design, and a new twin-lens camera set-up.

But does that make it a better phone? Throw in the brighter display and significant power boost, and we're tempted to say that yes, it probably does. We'll know for sure once we've finished with the LG G5 review.

From the 3OEM's the LG G5 is the one who makes me the most exciting.

I know it is preliminary but I really feel LG will be the one to trail this year. The S6 was a nice phone and the S7 will surely improve on it but rumours about the soundchip have faded and apart from that they went the predictable road while LG seemingly is going to throw things around.
HTC for off with a great start of rumours but the latest rumours aren't suggesting much exciting.
2016 might actually gives us a surprise and have LG as the one to beat

Got my eye on this one ;) Loved my Optimus G pro 2 so if if the G5 is everything it's expected to be I may be buying one very soon.

I am not gonna just let this go just yet.

LG G5 look extremely void. It has no distinguishing features as the G4 definitely did. It looks like an iPhone which i personally think is very UN. They should stuck to the ergonomic form of the G4 (namely the rear buttons and the slight curve). Those are the 2 things that made G4 the sexiest phone out there.

Now this boring version that will not out sell the G4 mainly because LG did not stick to the previous design. Instead they acted like a corp without a rudder or conviction. iPhone is popular because they stick to their own philosophy of design. You can see it throughout all of their product lines down to the watch and up to their MacPro which i have used for nearly 15 years. I just do not like their phone OS or its design.

All LG had to do was leave the buttons on back, keep the curve and screen and......
• make the body a more elegant material
• go to a true octocore
• Keep the external sd
• improve the camera
• up the battery to 4200mah
• make it more water resistance IP58
• and why didnt they just make the screen or a part of the screen have the ability to read a fingerprint. Knock Knock ... finger touch, open even

They are not going to get a warm reception as they have removed their signature elements. The things that made it great are no more. All thats left is MAYBE the LG UX, the camera, and ..... well the ips screen is gone now too. Hello over saturated everything.

Rear buttons are a brilliant idea, they shouldn't give up on it.

Battery slot is also brilliant which I've been thinking for years... The phone will have a tiny internal battery that will keep the phone running for a few minutes, while you replace the battery with a charged one just like reloading the magazine of a weapon.

Android (practical) is for men, iPhones (fashionable) are for women and gays.

I presume you fall into the latter camp?

Insults and negativity is the easiest thing to do. Your comment is like a high school kid and i think you should grow up. I am sure you could have produced an opinion or some relative statement but you didn't try. that was very lazy accept for the work you put in to prove you have no ability form an opinion on this topic.

What's insulting/negative about being a woman or a gay? Are you a misogynist/homophobe?

The G4 actually had a very strong start in its first 3 months and ONLY in the US. Both Asia and Europe it isn't selling all that great.

I do agree it is a shame to see them nice the buttons from the back to the side. It distinguished LG from the pack.
But, although marginally, the G3 still looks better then the G4 in my opinion and I can't put my finger on it why exactly that is because their fronts look quite similar. The G4 is bigger though and both the curve as the leather backs were gimmicks that don't do the design good.
Now with a leak of the M10 by Evan Blass I feel even more sure the G5 has a big chance to be successful even with the regretful decision of moving the buttons to the side. One thing though, yes, Apple has a very outspoken design language which you see in all of their handsets. I am convinced you can't do that with people who choose an android OEM over Apple. I might be wrong but it feels to me Android users expect more than just another iteration of their previous handset

Really? Is this your best at trying to give an intellectual response to Jeff R's valid remarks and point of views? I am in the anti Apple camp but at least I know why. Seems you are clueless why people actually take an Apple and within recognising your own mental limits you just differentiate users of either platform with terms that seem very common in your clearly unlimited vocabulary.

No distinguishing features...despite being the first modular smartphone, the first all metal smartphone without antennae bands, and having two rear cameras.


March 29, 2016, 7:17 am

But your comment is the one that came off with a negative connotation... You were trying to insult or neg the original commenter. Not stating a fact-based opinion.


March 29, 2016, 7:29 pm

No, but I don't think so.

er, well you wrote that fashion is for women & gays while practical is for men. Perhaps you can't see why that is negative?
