OnePlus 5 vs. iPhone 7 Plus vs. Samsung Galaxy S8: Flagships unfazed

Flagships unfazed

GSMArena Team, 28 June 2017.

Display

The OnePlus 5 has kept the same 5.5-inch display as the 3T - not just the same diagonal, resolution and technology, but the exact same panel, as AIDA 64 reports. We would have liked to see the FullHD resolution dropped in favor of QHD, especially given the panel's Diamond pixel arangement.

The iPhone 7 Plus's screen is a 5.5-inch FullHD unit itself, only it has an equal number of the three primary color subpixels.

The Galaxy S8 has the highest screen resolution, actually surpassing the QHD's 1,440x2,560px resolution. It is after all, in a stretched up 18.5:9 aspect, allowing it to fit a panel with a 5.8-inch diagonal into the width of 5.2-inch 16:9 one. With all the implications of that, of course - positive (more screen estate, comfortable single-handed use) and negative (pillarboxing, potential scaling issues) alike.

Samsung Galaxy S8

The iPhone 7 Plus wins the maximum brightness contest as it's able to push about 60nits more in Auto mode than the Galaxy S8 can muster. The OnePlus's Auto mode doesn't bring a boost and the OP5 is the dimmest of the three in challenging conditions. The AMOLED can be dialed down all the way to 2nits, while the iPhone's LCD goes as low as 4nits, which is still perfectly okay for night-time scrolling.

The iPhone can't compete with the AMOLEDs for contrast - infinite is more than 1400:1, good as the 7 Plus' reading is.

Out in the sun, it's the Galaxy S8 that snatches an easy win. Being the all-time highest scoring phone in our sunlight legibility test and all. The OP5 is in the middle, suffering a slight dip in contrast compared to the 3T. The iPhone 7 Plus comes in last, though it's posting solid numbers for an LCD.

Color accuracy is spectacular on all three phones. That is, the iPhone's display is super accurate out of the box, while the Galaxy S8 and OnePlus 5 need to have the relevant display modes enabled in settings, but the end result is practically the same. All three are able to reproduce the sRGB and DCI-P3 color spaces with an average DeltaE of less than 2.

The Galaxy S8 supports HDR10 video for which you need to head over to Amazon video. The other two don't offer the feature.

Display winner: Samsung Galaxy S8. The highest-resolution display of the S8 is also the most contrasty in the sun, and max brightness is excellent as well. HDR10 support is a nice bonus too.

Connectivity

None of these has an FM radio receiver - just getting this out of the way.

The OnePlus 5 and the Galaxy S8 come with the same Snapdragon 835 chipset, though an Exynos 8895 version of Samsung's top dog also exists (with marginal difference in connectivity features). That said, the OP5 has its LTE limited to Cat.13/12 for a theoretical maximum download speed of 600Mbps and 150Mbps upload. Meanwhile, the S8 supports Gigabit LTE. The iPhone 7 Plus' download speed is capped at 450Mpbs, or Cat. 9.

The OnePlus 5 is a dual SIM device by default, while the S8 comes in both single SIM and dual SIM versions, but some markets may only get one of these versions. The iPhone 7 Plus only exists as a single SIM device.

All three phones support dual-band Wi-Fi - b/g/n in the 2.4GHz spectrum and a/n/ac over 5GHz. Bluetooth is superior on the S8 and OP5 - v.5 comes with improved range and speed over the iPhone's v4.2. NFC is available on all three of them, though Apple only enables it for Apple Pay, while on Android you can read NFC tags and set up other connection triggers.

The Galaxy S8 supports positioning on all mainstream systems - GPS, GLONASS, BeiDou, and Galileo. The OP5 skips the European Galileo, while the iPhone only does GPS and GLONASS.

Wired connectivity sets the three apart too. The iPhone uses the proprietary Lightning connector, which supports USB 2.0 speeds. That's not all that's limited on the iPhone though. USB Host support only lets you attach some certified accessories or access your digital camera storage via proprietary adapters that are separately sold. You can pair a Bluetooth keyboard to the phone should you need this sort of peripheral. In the absence of a 3.5mm jack, Apple bundles a Lightning-to-3.5mm adapter. Woo-hoo.

The OP5's USB-C port is capped at USB 2.0's 480Mbps, too. Not all USB-Cs are created equal, however, and the S8 adheres to USB 3.1 for transfers for transfer speeds of up to 5Gbps. The S8's USB-C can also output video at 4K/60fps with the right type of cable. It can additionally turn into a desktop computer via the DeX docking station, complete with a monitor, keyboard, and mouse.

Connectivity winner: Samsung Galaxy S8. The S8 has the widest range of connectivity features, simple as that.

Battery life

The OnePlus 5 packs the highest capacity battery of these three, a 3,300mAh unit that's still marginally smaller than the one in the preceding model. The Galaxy S8 relies on a 3,000mAh cell, while the iPhone 7 Plus is fitted with a 2,900mAh power pack.

The three phones have pretty much the same area to light up - the Galaxy's 5.8-inch display is only 2% larger in screen real estate theoretically, but with the rounded corners it may actually end up being smaller. Then there's the matter of LCD vs. AMOLED, and that's before we get to iOS vs. Android. From a user's perspective, that's hardly relevant, though - let's look at the battery life numbers.

The iPhone 7 Plus trails in overall endurance but has one important advantage - its thirteen and a half hours of web browsing over Wi-Fi will have you scrolling two and a half hours longer than on the OP5, and three and a half more than on the S8.

It's a completely different story in video playback, where the AMOLEDs have a clear advantage. To the tune of almost 19 hours vs. barely 8 in the case of OnePlus 5 vs. Apple. The Galaxy S8 can't quite match the OP5 in this area, but it still outlasts the iPhone 7 Plus by a whopping 6 and a half hours.

The Galaxy S8 is the most efficient in 3G voice calls - arguably the least important of these three tests but still - it's one win each. It should be noted that we've tested the Exynos version of the S8, and Snapdragon 835 phones have proven less frugal in terms of standby and voice call longevity.

OnePlus 5

Apple iPhone 7 Plus

Samsung Galaxy S8

The OnePlus 5 charges super fast with its proprietary Dash charge tech, but you need to have the charger and cable on you for it to work. Apple supplies a downright inadequate 5V/1A with the 7 Plus that takes more than 4 to top up. The Galaxy S8 supports QuickCharge 2.0 (not 3.0, and not 4.0), but that makes it compatible with most chargers. On top of that it also supports wireless charging unlike the other two.

Battery life winner: Tie. iPhone 7 Plus snatches the victory in web browsing, which some believe to be the most important metric, but loses in the other two tests. The OnePlus 5 is the undisputed champ in video playback endurance, while the S8 rules in voice calls and edges the OP5 in overall rating. Wireless charging is another one in S8's favor, and that could make it the winner for you.

I agree with you bro. Android has more functions than of apple devices. More customizable, awesome UI than apple, cheaper, more accessible system configuration, high end specs(if you have a flagship device) etc..
