F7 Pro - Review (part 2)

Battery Life

I have measured the real battery capacity using my USB Tester, and it seems that Real Battery Capacity is much lower than Declared (Declared: 4000mAh | Real: ~3500mAh). As i always do when i get this incorrect measurements, i will update it after some battery cycles to have a 2nd Confirm.

With the latest GeekBench 4 Update there is no battery test anymore, so i had to use PCMark to get something to rely on. Result: 8h 51m

As regards battery charging times, the 5V/2A charger seems to recharge the device pretty fast, but there isn't any Ultra-Quick Charge support such as MTK Pump Express, so can't expect to recharge the device is less than 1 hour.

Software

Luckily DOOGEE doesn't customize the software with useless Custom UIs or anything else, providing a pure AOSP experience just like on Nexus Devices. As on all latest devices, it is running Android 6.0 Marshmallow (upgradable to Android 7.0 Nougat? I'll ask DOOGEE for this) with some extra-apps installed (just like on the DOOGEE T5) such as "Bagan Keyboard", "Xender", "Documents to Go" and "Parallel Space". Don't worry though, they can be disabled/uninstalled without issues.

Just like other last-gen Mediatek Devices, there are some typical, and now pretty common, features such as Gestures, Scheduled Power On/Off, etc…

Notification LED settings are simple, the color isn't customizable but still better than nothing.

As regards the Fingerprint Scanner management, it is pretty easy to configure, pretty fast unlock times with no issues as regards its accuracy.

Being a flagship we all might expect a full range of sensors, and here it is. Gyroscope, Magnetometer and Barometer are there!

Thanks to the clean OS, and to the powerful CPU/GPU, there are no issues at all with UI smoothness and Apps Loading speeds. I managed to run any kind of app without facing any single lag. Pretty Impressive, and benchmarks will confirm it. Follow the next paragraph to know more.

Benchmarks

I have used 3DMark, AndroBench, Antutu Benchmark, Epic Citadel, GeekBench 4 (CPU & Compute), GFXBench, PCMark (Work & Storage) and Vellamo to stress the device to the limits. I won’t test Games or Video Playback because there are already some related tests included in these Benchmark suites.

3DMark – GPU Performance on OpenGL 2.0 tests is awesome, while OpenGL 3 tests seems to require a bit more power to get a smooth result. Software Optimizations are required.

AndroBench – eMMC Performance confuses me a bit. Reading Speed is pretty high, but Writing Speed isn't. Needs to be more balanced.

Antutu Benchmark – I won’t say a lot about this benchmark, this isn’t as reliable as others. I’m providing this just for benchmarks lovers.

Epic Citadel – As you can see, 3D Performance is maxed out. VSync limits the GPU power to 54.5fps, so this is the maximum this benchmark can record. Great!

GeekBench – CPU Performance is so high that Geekbench isn't able to get some comparision values haha. Just check the screenshots. Compute Benchmark that uses GPU power might have been better though.

GFXBench – As already said for the 3DMark benchmark, OpenGL 3 tests need more power to run smooth.

PCMark – Somehow the Writing Score is lower than others, but the main score is pretty high. Storage Score, as already said for the AndroBench benchmark, confuses me a bit.

Work

Storage

Vellamo – Chrome isn't ready yet for 10 CPU Cores, but the built-in Webview is...awesome. As regards the CPU scores, you can easily see how fast it is.

This Mediatek Helio X20 SOC is a beast, but i need to ask DOOGEE to optimize GPU performance in order to use this beast to the maximum, it can definitely perform even better!

Conclusions

Being the first DOOGEE device to provide an high-end CPU such as the Helio X20, this is definetely i step forward to DOOGEE trend. They managed to produce a compact, fast and cheap-enough device that provides almost everything that an user is searching for an high-end device that doesn't cost more than a PC. Even if some minor negative aspects are there, such as the missing quick charge support, battery capacity seems to be lower and camera needs some software improvements, for this price it is definitely a best-buy.
