POCO recently launched the POCO F4 Series which again puts forward super fast performance at pocket-friendly prices. Interestingly, in the F4 series for the first time, POCO has embedded OIS (Optical Image Stabilization) in its main camera.
Curious as to what the POCO F4’s capabilities are both in terms of performance and camera? Come on, just take a look at the reviews!
When compared to F3, the appearance of the F4 looks fresher thanks to the now flat edges, and the camera frame with a more defined angle. The design concept can be said to tend towards modern minimalism. There are no trendy and bold elements typical of POCO which symbolizes the spirit of youth.
With flat edges, in terms of operating comfort, the POCO F4 is a comfortable device to grip. It is 7.7mm thick and weighs 195 grams. It’s still ideal to put in a trouser pocket, including if it’s paired with the default softcase.
The color variant that came to our test table was Nebula Green. The green color is a bit dim aka less bright even though the finishing is glossy. Suitable for those of you who want to look calm but are a bit bored with standard colors like black. A little note, this glossy back panel is not easily dirty by finger marks.
Turning to the front, you are again presented with a screen with a 6.67-inch flat panel that has a tiny punch hole in the middle to accommodate the selfie camera. POCO also doesn’t forget to include protection through Gorilla Glass 5.
At the bottom there is a USB-C port, speaker hole, and mic. There is no 3.5mm audio jack port, but the good news is that POCO has included a USB-C to 3.5mm converter in the packaging of this phone. There are two SIM-card slots as usual, but without a microSD slot. The POCO F4 is a device with an IP53 rating for resistance to dust and splashes of water.
120Hz AMOLED screen
The POCO F4 features a 6.67-inch FHD+ AMOLED E4 panel with a refresh rate of 120Hz and a touch sampling rate of 360Hz. This screen has a brightness level of up to 1300 nits and is equipped with HDR 10+ support. In addition, there is also an interesting improvement on the screen in the form of Dolby Vision support.
In our opinion, this phone screen is quite pleasing to the eye. There are three color modes that you can choose from, namely Vivid (DCI-P3), Saturated (DCI-P3 with raised saturation), and Standard (sRGB).
The refresh rate can also be set between Default and Custom. The former can also be called automatic and will adjust the refresh rate according to the application you are running. If it’s Custom, you can lock it at 60Hz or 120Hz.
Overall we have no complaints about the POCO F4 screen. Outdoor use during the day with the hot sun is still comfortable. For the need to watch movies from popular streaming platforms, there is also no problem because it is supported by Widevine L1.
Fun again, the POCO F4 audio sector relies on stereo speakers located at the bottom and top of the device. Besides the sound quality is quite loud and powerful, you will also find Dolby Atmos features here.
The first POCO phone with OIS
As mentioned at the beginning of the article, the POCO F4 is the first POCO smartphone whose camera has been equipped with OIS. The rear camera configuration includes 64 MP f/1.8 with PDAF and OIS, 8 MP f/2.2 ultra-wide, and 2 MP f/2.4 macro.
It can be seen, in addition to OIS, the increase in the F4 camera compared to F3 also occurs in the main sensor. Previously 48 MP, now 64 MP. The existence of OIS itself is believed to be able to make the photos and videos more stable. The selfie camera is still the same, 20 MP f/2.5.
As far as our testing goes, the photo quality of the POCO F4 main camera is quite good. In ideal lighting conditions, high detail is captured and the color reproduction looks vivid with the right contrast and good color accuracy. The noise reduction is minimal so it doesn’t reduce the sharpness of the image. The dynamic range is also wide.
Although it is not equipped with a depth sensor, the POCO F4 still offers Portrait mode with a neat and natural bokeh effect. While the wide-angle camera can also provide photos with good detail and color, even the dynamic range is above the average ultra-wide camera on other 5 million cellphones.
Switching to indoor shooting with slightly dim conditions, the POCO F4 is able to maintain good detail, contrast, and saturation while keeping noise at a low level. The presence of OIS has proven to be very helpful in reducing the possibility of blurry photos due to unstable hands, especially for night shooting with Night Mode.
How about videography? The POCO F4 rear camera is capable of recording up to 4K resolution at 60fps. Quite special in its price class. Unfortunately, the front camera is stuck at 1080p 30fps only. Here are the recordings using both the rear and front cameras, which we both set at 30fps to make it more stable:
Fast performance, safe temperature
In our opinion, the Qualcomm Snapdragon 870 which is the weapon of the POCO F4 is still very reliable for various needs, including gaming. Even so, the use of the same chipset as the previous generation makes this phone less tempting for F3 users who want to upgrade.
Apart from being fast, one other thing we like about the Snapdragon 870 is its temperature which is easy to tame. This time, POCO uses LiquidCool Technology 2.0 with a vapor chamber measuring 3,112m² for optimal heat dissipation. As a result, the temperature can be controlled at a safe and comfortable level without compromising performance.
For gaming, POCO F4 is clearly capable of running heavyweight titles like Genshin Impact, even in the Highest 60fps graphics setting. But if you want to reduce the possibility of throttling and wasteful power consumption, we recommend playing on Medium settings only. For games like Mobile Legends or PUBG Mobile, it certainly runs smoothly without any problems.
There are two memory variants available, namely 6/128 GB and 8/256 GB. The RAM technology is LPDDR5 while the storage is UFS 3.1. Remember, the F4 doesn’t have a microSD slot. So if you are a heavy user who often stores large photo, video or game files, we recommend choosing the 256 GB variant.
This smartphone has a 4,500 mAh battery supported by 67W Turbo Charging technology. This capacity still allows for use from morning to night, with our usage style which tends to be moderate. For charging, from conditions below 10 percent to full 100 percent only takes about 40-45 minutes.
Just like its predecessor, the POCO F4 is a device that offers flagship-style performance at a more affordable price. The difference is, now there is additional OIS and faster charging capabilities. Including tempting in its price class, but the upgrades offered are not too significant for users who already have F3.
For those who are interested, the POCO F4 is sold, the POCO F4 6GB+128GB is sold at a price of USD $346 and the 8GB+256GB variant can be redeemed for USD $380.
POCO F4 is suitable for:
- Student/student: Excellent performance. Great for studying, creating content, or playing games.
- Gamers: F4 can be invited to run all games smoothly, including those that demand heavy graphics such as Genshin Impact.
- Content creators: The presence of OIS makes this phone ideal for on-the-go work, with results that are fairly good for its price class.
- Mobile employees: In addition to its agile performance, the F4 also supports high-speed charging. Suitable for employees who are always on the move and don’t have much time to charge.
- Movie fans: The screen of this phone is quite a treat for the eyes. It’s Widevine L1 as well and supports Dolby Vision.
