Infinix Note 4: All You Need To Know (Specs and Review)

The Infinix Note 4 is a 4G smartphone with a 5.7-inch display and a 4300 mAh battery coupled with fast battery charging. In other words, it is being true to the spirit of Infinix Note devices – a big screen and a big battery. The perfect picture of a device for people on the go.

There is a front fingerprint sensor here as well, though the Xpen is absent. You will have to buy the Note 4 Pro to get your hands on the Xpen. Or perhaps buy it separately.

Infinix Note 4 Price In India

You can find the Note 4 to buy for as low as Rs. 8,999. That is the current best price. It costs more than that in a number of outlets across India and neighbouring countries. It is available on Flipkart and at online and offline retailers.

Infinix Note 4 Review (in use)

Our Infinix Note 4 review is ready after weeks of using it. There was a lot of hype surrounding the Note 4 before its release. It isn’t quite as sexy as its twin brother, the Note 4 Pro, but that isn’t the issue. The question is, Does it live up to its own promises? Let’s find out.

Infinix Note 4 Review: Design

This is a big phone. If you are familiar with Infinix’s Note series, that should be no surprise. Because of the size, one-handed use is difficult if you do not have really big hands. It is also fairly heavy and has some bulk. Perhaps it is the poly-carbonate shell responsible for some of that, but we think the Note 3 feels easier on the hand.

The volume keys and power button are on the right side of the phone. Below the display is a central hardware Home button with fingerprint sensor embedded. The position of the fingerprint sensor is a reminder that this is a 2017 smartphone.

At first glance, it might appear that the Note 4 has stereo speakers, but that is far from the truth. The two “loudspeaker” grills at the bottom edge are not hiding stereo speakers.

The phone has a removable back cover, though the battery is not removable. The two micro-SIM card slots and dedicated micro-SD card slot are all accessible from there though.

Infinix Note 4 Review: Software

Out of the box, the Note 4 runs Infinix’s custom UI, called XOS, layered over Android 7 Nougat out of the box. However, it already got a software upgrade to Android Oreo in early 2018.

XOS is light and breezy and includes all sorts of nifty tools. Some include the ability to block numbers for calls and SMS. The drop-down menu also gives the user direct access to several useful features, including toggling ultra power mode, high performance mode, do not disturb, screen recording, cast and scroll-shot, among others.

The device supports split screen, which allows you to view and use two apps at the same time.

One nifty feature is that from time to time, you are notified of the power intensive apps on the phone.

XOS has a number of apps pre-installed though. These include: Ultra Power, XManager, XAccount, XClub, XHide and XWeather. While they may provide some utility, depending on your needs, none of them are uninstallable. In other words, bloat.

Phoenix is a new web browser by Infinix, and it is pre-installed on the Note 4. Our experience with it has been poor though. It keeps crashing and we have not been able to use it for any serious web browsing. Thankfully, Chrome is on the device too, and we turned to that for our browsing needs.

Infinix Note 4 Review: Network, Telephony

Voice calls on the Infinix Note 4 are good, clear, and sufficiently loud.

If you travel to the United States, you will like that the Note 4 supports the two bands used by US GSM networks, so the phone is good for voice calls on that business trip to the United States.

Infinix Note 4 Review: Display, Audio, Video

The Note 4’s 5.7-inch display is exactly what fans of big displays want. It is bright and sharp at 386 PPI. The 2.5D glass is smooth and nice. There is no mention of protective glass though.

The loudspeaker on the Note 4 is loud and offers fair audio quality. Coupled with the beautiful display, watching videos on the phone is a pleasant experience.

Infinix Note 4 Review: Cameras

Infinix Note 4 review back
The Infinix Note 4 has a 13 megapixel rear camera with auto-focus and dual LED flash. On the front, it has an 8 megapixel unit for selfies.

The selfie camera does well but isn’t fantastic. Here is a sample indoor shot with flash:

Here is another indoor shot with no flash:

The main camera captures acceptable levels of details. Here are two samples taken indoors in Normal mode:

In low light situations, both cameras struggle quite a bit and are not so accurate in colour reproduction. The phone makes up for it with a range of 9 pre-set filters. That way, you have more control over how your photographs turn out. They can be more vibrant or cooler or come out in monochrome. The playground is yours.

Infinix Note 4 Review: Multitasking/Performance

Infinix Note 4 review top
The processor of the Note 4 is an octa-core 1.3 Ghz unit, coupled with 2 GB of RAM. In daily use, you will notice a small pause as you launch and switch between apps. That is expected, considering that the Note 4 has a big display and more pixels to push with that combination.

If you are interested, here are the benchmark results that the phone posted:

  • Geekbench 4: 623 Single-Core; 2672 Multi-Core
  • AnTuTu 6: 38,474

The Note series devices have never been big on raw performance. The display and battery are their strong points. But it is sort of sad that even the Note 3 got marginally better benchmark scores a year ago.

Infinix Note 4 Review: Battery life

With a 4,300 mAh battery, the Note 4 provides very solid battery life. And there is fast charging too, thanks to Infinix’s XCharge technology. It works with the included charger. The big battery means your phone won’t die fast and XCharge means you can always top up fast. A win-win.

Infinix Note 4 Review: Final Words

The Infinix Note 4 is not a very exciting smartphone, especially if you have used its predecessor, the Note 3. There are no huge updated features.

There isn’t much of an upgrade in here. Perhaps 4G LTE is the main upgrade feature from the Note 3. If you are considering buying an Infinix note smartphone for the first time, it is a solid phone that should meet most of your needs.
