Call quality

There’s nothing out of the ordinary to say about the calling performance with the Galaxy S8+. There may be just a bit of getting used to, due to the earpiece being situated on such a thin piece of bezel, but it’s by no means an issue.

Voices through the earpiece tend to sound OK, but not pleasing.

Battery life

Solid performance, but do yourself a favor and turn Always-on Display off

The big, 3500 mAh battery is one of the major things that separate the Galaxy S8+ from the S8. The phone holds up quite well, actually, easily extending in to a day and a half of use. Stand by times don’t seem to be very good, however, which is probably due to the Always-on display feature. Given its limited use, we’d recommend disabling Always-on display, and in turn enjoying the benefits of a very real battery life boost.

Samsung gives us some interesting statistics for this wirelessly chargeable battery: it can go for the awesome 18 hours of continuous video playback, or the cool 78 hours of music playback. Web browsing on Wi-Fi or LTE can last for 15 hours, all of which are slightly better results than those of rival iPhone 7 Plus.

The jumbo Galaxy did pretty decently on our custom battery benchmark, lasting for exactly 8 hours. This is a bit more than last year’s S7 edge (7 h 18 min), as well as the Pixel XL (7 h 19 min), but behind the iPhone 7 Plus’ 9 h 5 mins.

Recharging the battery from 0 to 100% happens quite quickly for the capacity, in just 1 hour and 40 minutes. This is the same time it takes the S7 edge to charge, and slightly quicker than the Pixel XL (1 hour 58 mins). It’s also significantly quicker than the Huawei Mate 9 (2 h 22 mins), and way quicker than the iPhone 7 Plus, which takes 3 h 17 mins.

Battery life (hours) Higher is better
Samsung Galaxy S8+ 8h (Excellent)
Samsung Galaxy S7 edge 7h 18 min (Good)
Apple iPhone 7 Plus 9h 5 min (Excellent)
Google Pixel XL 7h 19 min (Good)
Charging time (minutes) Lower is better
Samsung Galaxy S8+ 99
Samsung Galaxy S7 edge 99
Apple iPhone 7 Plus 197
Google Pixel XL 118


The Samsung Galaxy S8+ is and isn't a big deal, depending on how you look at it. If you happen to have some degree of sensationalism in you — a quality that many of us tend to exhibit these days — you may be inclined to say that the S8+ is a revolution!, that the Infinity Display is unlike anything you've seen before!, and that overall, it's the best smartphone ever, period!

To the non-sensationalists out there, however, it's clear this isn't exactly the case.

The Galaxy S8+ gets many things right. In fact, it's probably the best Android smartphone for users who need an extra-large display. Not because it's necessarily the best in all that it does, but because it's such a strong all-around package. It's really difficult to find an area where the GS8+ doesn't perform up to standard.

The single most important feature that's supposed to propel the Galaxy S8+ to the top of the charts must be the bezel-less display, because it really is the only significant thing separating the S8+ from the S7 edge. Sure, stuff has gotten slightly better across the board, but not to the point of becoming a meaningful upgrade. The bezel-less screen, however – that's something new! And is it a game changer? In terms of how we use the smartphone – not really, but it works great here on the Galaxy S8+, because it's supposed to be a very large phone. And with such large phones, each and every millimeter counts. That's what Samsung has managed to get right here, as the Galaxy S8+ would have been a humongous handset, were it designed with bigger bezels around the screen. Instead, it almost feels as manageable as a normal 5-something inch phone like the Galaxy S7 or the LG G6. Not quite, but almost. And that's great!

The GS8+ doesn't have to be the best phone in order to be a great phone. There are rivals out there with slightly better cameras, considerably better performance, and more affordable prices, but that's not the point. The point is this: if you want an Android phablet that screams premium, offers almost every possible feature there is, and handles every task with an impressive degree of excellence, you don't need to look elsewhere, because the Galaxy S8+ is right here, and it gives you all that.


  • A bold new form-factor
  • Solid all-around experience
  • State-of-the-art camera


  • Performance could be better
  • Screen colors are not too accurate

iPhone 7 Plus - 9.3 GS8+ - 9.0 iPhone 7 Plus wins. GS8+ =/= Phone of the year....and it's not even close. Let's sum this up real quick. A nearly year old iPhone 7 plus beats the S8+ in performance and battery life?

Let's see how many scores on Note 8 review. Note: They using Geekbench 4 as their "own" battery test, you may try it yourself and compare on your iPhone or other phones.

Since the iPhone 7 plus beats the S8+, there is absolutely no way the Note 8 is beating the iPhone 8 plus.

Beats the s8 plus in what? I've seen real world comparisons of both speed tests and battery test and the only thing the iPhone is good at is launching and relaunching games. Why because games are much more optimize for iOS than Android. When it comes to launching regular apps there's no contest! S8 hands down. The screen on time on the s8 is also way more than what you'd get on the iPhone plus. I really don't know where PA gets its stats from but I'm pretty sure it's not real world scenerios.

iPhone 7 plus is all the best all rounder phone. Other than big bazel iPhone 7/7plus beat this mediocre faceless looking phone easily. S8 plus has mediocre battery life, a weird aspect display, a faceless design. atrocious placement for a fingerprint scanner, useless bixby and bixby button, #hit loads of crapware and bloatware, very slow and buggy update policy camera is hardy a upgrade, last year pixel has better camera High chance of explosion This phone shouldn't get more than 6.5. PA is very generous to samsung phone as usual. Be glad that they gave them 9.

Such a child! Why would one compare an iPhone to an Android phone? They are really an Apple to Orange comparison. Can I buy a iOS device from Samsung, Sony or LG? There really only one choice for iOS device and that is Apple regardless.

On second thought, I know why, Lumbergh has a need to feel justified for getting an iPhone 7. Such child like behaviour. Shame...Shame...Shame.

The iPhone 7 Plus does not beat the S8+ (or even the S7 Edge) in any battery test except PhoneArena's. And their test has been suspect for years. The S8 won't be phone of the year only because the Note 8 will. The only reason the S7 Edge won last year (yes, it did win, like it is not) it's because the Note 7 was recalled.

iPhone 7 Plus - Bezels GS8+ - no bezels

Fingerprint placement should've been added as a con, and I would've also put the fact that we cannot remap nor disable the Bixby button.

60fps with a Qhd+ screen.if xiaomi's mi6 and the pixel 2 come with 1080p displays the s835 which usually has the slightly better GPU is going to be crazy on those

What a beauty. And that with IP68, a superb screen, superb camera and great battery life. I would give it a 10/10 if it only had FM radio and either a fingerprint scanner under the glass or under the camera on the back like the G6.

Had a chance to finally hold this phone and give it a spin. Looks way better in person and the feel of the phone is great. Looking forward to the real world usage and reviews.
