ASUS ZenFone 5Q review: Fighting for five
Performance & Battery Life
We mentioned in our review of the ZenFone 5 that we were not very impressed with its Qualcomm Snapdragon 636 chip. In Qualcomm’s 6xx series of mid-range processors, the 636 currently plays second fiddle to the 660, with both employing Kryo 260 (modified ARM Cortex-A73) cores.
The ZenFone 5Q, on the other hand, uses a Snapdragon 630 processor that actually uses a conventional Cortex-A53 core setup. You’d expect this to produce numbers for the 5Q that are somewhat different from the ZenFone 5, and actually closer to the previous-generation Snapdragon 625 chips.
To see if this is indeed true, our mix of devices today includes both the Snapdragon 636-toting ZenFone 5 and a Xiaomi Redmi 5 Plus, which employs a Snapdragon 625 - and which costs just S$299.
3DMark Sling Shot Unlimited 3.0 uses a mix of graphics and physics tests to measure hardware 3D performance. Qualcomm claims the Adreno 508 GPU in the Snapdragon 630 is 30% faster than “prior generation” devices. We’re guessing this means the Snapdragon 625/Adreno 506 combo in the Redmi 5 Plus going by our findings:-
BaseMark OS measures overall system performance over a number of different metrics. The ZenFone 5Q only manages to edge out the Redmi 5 Plus by 200 points, yet the gap between it and its more luxurious cousin is much bigger:-
Finally, here’s our standard battery test, which involves:
- Looping a 720p video with screen brightness and volume at 100%
- Wi-Fi and Bluetooth connectivity turned on
- Constant data streaming through email and Twitter
Now for the second big surprise of the day. Given that the 5Q has only a 3,300mAh battery, we expected it to be handily pipped by the Redmi 5 Plus, which has a larger 4,000mAh juice pack.
But no, the tables have been turned! The 5Q lasts almost an hour more than the Xiaomi!
In day-to-day use, the 5Q was certainly also able to power comfortably through an entire workday, and better yet, while it doesn’t appear to support any form of fast charging, a quick and dirty test seemed to confirm otherwise, with currents peaking at almost 2 amps on a Qualcomm Quick Charge 2.0 charger:-
