Samsung Galaxy A8 review: A-game

Display

Big screens are in and the Galaxy A8 matches the Galaxy Note's 5.7 inches. That's 0.2" bigger than the Galaxy A7 display. The Galaxy A series are more conservative with resolution than the corresponding S series phone, which in our case means 1080p resolution.

Still, 386ppi is above certain benchmarks of visual acuity. It beats Retina's 326ppi, but not the iPhone 6 Plus display, which is a 5.5" 1080p unit. Any difference you may notice in sharpness between those two (and we found it basically impossible) is due to the different sub-pixel design of Super AMOLED compared to traditional LCD.

It is a Super AMOLED though, these days OLEDs are rare and fans of true blacks and high contrast often have little elsewhere to go but Samsung. To its credit, Samsung has developed its screen tech and achieved accurate colors and high brightness.

If you boost the brightness slider you get to the level of a good LCD. Keep in mind that auto brightness mode can push the brightness of the screen noticeably higher in very bright conditions. The reflectivity is kept way down so you can be conservative with the slider even in broad daylight and still have a legible display.

Viewing angles are great though you might see a minor blue/green tint at steeper angles (it's not uncommon with OLEDs). The screen mode setting is available to adjust the color temperature, contrast and saturation. We found that the Basic setting provided the most accurate colors, though it sets the contrast lower than we're used to. If the image looks too bland to your taste, we suggest you go for the AMOLED photo mode, which is nearly as accurate but boosts the contrast along with the saturation of some colors. AMOLED video pushes colors even further, which one you use is a matter of personal preference.

Overall the screen is excellent for the price. It doesn't have the perfect clarity of the Galaxy Note5's screen, but the Samsung Galaxy A8 will satisfy all but the most discerning of users.

Connectivity

The Samsung Galaxy A8 unit we have is the Duos version, a dual-SIM, dual-standby phone. Both nano-SIM slots can be used to connect to 2G, 3G or 4G networks so you can slip a data card in either slot (or get plans with data on both, but only one can be used at a time).

This will get you up to 300Mbps downlink speeds on an LTE network, 42.4Mbps on a 3G network. You can enable Download booster if your local Wi-Fi is slow, it combines the speed of both LTE and Wi-Fi.

The Galaxy A8 has dual-band Wi-Fi a/b/g/n/ac support as well. Bluetooth 4.1 and ANT+ are available for power-efficient communication with smartwatches and sport trackers. There's no NFC though - this means no simple pairing, no Samsung Pay either.

The other small letdown was the wired connectivity - microUSB 2.0 is run of the mill, but we were hoping for some MHL action. It does have USB OTG though. If you've never used wired TV out or NFC tags those are non-issues, but they are worth keeping in mind for everyone else.

You do get screen mirroring on supported TVs and MirrorLink for cars (if your head unit supports it).

Battery life

Fans weren't happy about the Galaxy Note5 battery getting smaller and getting sealed in. The Galaxy A8 is pretty much in the same boat, 3,050mAh of sealed battery. So is there cause for concern?

No, as it turns out. Our phone aced the battery tests, getting over 12 hours in both web browsing and video playback, plus a whopping good time in the call test.

Our phone, which is the Exynos 5430 version. That chipset is built on a 20nm process and did a wonderful job in the Galaxy Alpha even with its tiny battery.

The other version of Galaxy A8 uses Snapdragon 615, a 28nm chip. True, it lacks the fast, power-hungry Cortex-A15 cores, but we expect different results due to the older manufacturing process.

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.
