Infinix Note 4 Review After 15 days

Infinix Note 4 Front

Launched in the Philippines middle of this year, the Infinix Note 4 has been making waves among those in the market for a quality midrange smartphone. Since our satisfactory experience with the Infinix Zero 4 Plus, we were curious how the Note 4 would fare well in comparison. We put the Note 4 through its paces as a regular user for more than two weeks and were not disappointed with the results.

Infinix’s Note 4 was introduced to the Philippine mobile device market July 2017.  The smartphone comes with a hefty set of features that do not disappoint.


Colors do not appear washed out and images are rendered clearly on the handset’s powerful screen. Like other smartphones, it struggles somewhat under the noon-day sun, but that is to be expected from most devices at this price range. This is not much to complain about since the phone adapts itself to the brightness and lets you easily make further adjustments to your liking.

Responsiveness is very fluid thanks to its 3GB RAM. No lags were experienced with a lot of its bundled apps opened at the same time.


Its octacore, 64-bit Mediatek 6753 1.30 GHz Cortex processor and Mali-T720 GPU promised to deliver a seamless UI experience – a goal it accomplished nicely during our 15-day usage of the phone. Here is an estimated breakdown of our daily use:

3-4 hours/day on social media
2 hours/day average watching YouTube
2 hours/day casual gaming (Asphalt Extreme: Rally Racing, Mobile Legends, Real Boxing 2)
30 minutes/day average calls
20 minutes/3 days taking photos and videos
1-2 hours/day surfing the web
2 hours/day listening to podcasts/music/radio

The above activities resulted in us having to recharge the battery every other day.  This means that its 4300 mAh battery lasts about 1.5 – 2 days before needing a recharge.  Gaming on this device is great if you are a casual gamer. It is not recommended for graphically intensive gaming despite the quality display and ample battery capacity. Playing games for 3 to 4 hours on end caused the back to heat up considerably.  Some lag was experienced. The battery drained very fast. It is recommended that games be played on this device on low or medium settings, and up to 2 hours for each session to avoid battery issues.


The front 8MP camera functioned satisfactorily when selfies were taken.  Image and color quality can be rated slightly above average depending on the situation.  It is safe to say that the selfie camera is suitable for indoor or moderately bright environments. The front LED flash helped as can be seen in the example below.

The primary 13MP camera on the other hand is good. Pictures generally produced by this camera appear vibrant and clear especially when shot at a short distance. A professional mode is available if some settings need to be changed for better shots. Dual flash can be a boon, or can be a disaster depending on the situation as shown in the following photos.

Here are some photo samples captured using the Infinix Note 4’s cameras. (Note: Pictures were resized for web publication. No filters were used.)

Videos are clear but could use some lighting assistance when it comes to shooting in dimly lit areas.


Infinix Note 4 is run by Android Nougat with Infinix’s XOS UI.  It also comes with a lot of useful apps from the XOS family. These apps are very helpful and convenient.  If you find that some of the apps are not necessary or you prefer something else, simply disable or uninstall the apps you need. Read our review of the Infinix Zero 4 Plus to learn more about these pre-installed apps.


The 32GB storage is adequate for most users. If more space is needed, it could be expanded to a maximum of 128GB with a microSD card. The slots can be accessed by removing the rear cover.


A few improvements can be made with the fingerprint sensor, and the power and volume buttons. The former can take some time getting used to if you are accustomed to using a fingerprint sensor situated at the back of a phone. The buttons feel a little too small, but that can be chalked to preference.

The body, though not made of steel, is done masterfully. It feels light and easy to grip and the sheen it shows when the light hits it rivals the looks of premium phones.

The bottom line: at this price point, we find this smartphone a very good choice if you want a device that has a long battery life, good cameras, go for this midrange phone.
