Infinix Note 4 Pro Review: Solid, Stylus-Equipped Phone

Similar to any new company that sets out to conquer a certain market niche that is already occupied by legacy corporates, Infinix has endured and crossed muddy waters in making their brand known to Kenyan consumers. Often, this is not an easy fight and it is fashionably impressionable about how the Chinese brand has managed to remain relevant among the ever-increasing smartphone consumers (because our grandmothers want smart handhelds since clicking on hardware keypads is giving them blisters, and that’s so pre-colonial).

This is the period when the budget segment is littered with several smartphones, giving you no excuse to hold tight to your 2003 Motorola T190, and Infinix is here to disprove your life choices by offering a broad range of devices to phase out your beloved Moto or Sagem 3020 (new millennium kids will think I’m speaking in tongues but in your defense, Sagem was an actual device with polyphonic ringtones to boot).  Could you even store more than 20 contacts addresses in that phone? These are the issues that the Infinix brand is out to fix, in addition to ensuring that you stay in touch with the world of unknowns, where you can make friends with people you have never met, call them friends in platforms called apps such as Facebook and WhatsApp (they come preinstalled, FYI) as well as ensuring that such interactions are kept on toes with appreciable speeds, which the Infinix Note 4 Pro we are reviewing today is equipped with in the name of 4G LTE.

Summary

The Infinix Note 4 Pro complements the Note 4 that we reviewed a couple of weeks ago. The device is part of Infinix’s marketing strategy in meeting the phone requirements of different demographics in the Kenyan market. Specifically, the Note devices have always been deployed for users who love big displays and humongous batteries to tickle their fancy. The Note 4 Pro does just that, and brings a stylus along that has been creatively dubbed as XPen. Although we would have loved a robust approach to the functionality of the stylus, we cannot deny that Infinix’s first attempt is acceptable considering the device costs less than KES 20,000.

Largely, the device keeps the exact spec sheet of the Note 4, save for minor changes in memory where internal storage is capped at 32 GB and 3 GB of RAM. Generally speaking, the two siblings’ hardware performance are identical because the quad-core MediaTek MT6753 1.30 GHz chipset has been recycled a couple of times, and while that is a favorable decision to keep the cost of the device low, Infinix would have made us happier by adopting a modern, midrange CPU for additional horsepower.

Save for a couple of Xpen-specific software tweaks for people who love taking notes, XOS is the same to what we saw on Note 4. More similarities are seen on the device’s construction and the location of hardware controls. The screen’s footprint remains at 5.7”, and so are the cameras as well as the fingerprint scanner that is embedded in the hardware home button flanked by non-lit capacitive keys.

The 4500mAh battery is large enough to get you through a heavy day, and that can extend to two days if you are a light user. Contrastingly, I believe the Note 4 has better battery life, although both can be topped up by quick charge that Infinix has named XCharge.

Lastly, the Note 4 Pro is excellently built. Once you hold it, it becomes apparent that a sub 20K price tag is a steal. Our review unit is painted black and you just need to interact with it to establish its premium build.

Hardware and Build Quality

As mentioned, the Note 4 Pro is built like a high-end device but does not stay away from what we have come to expect of midrange phones. The metallic back feels absolutely premium, and so is the front that is covered by a large 5.7-inch screen, which is a significant drop from the Note 3’s panel. However, the onscreen buttons and rear fingerprint scanner have been replaced by non-lit capacitive keys and a front-facing hardware fingerprint sensor. This makes it look like the Note 4, only that the Pro is a unibody slab. The vertical edge on the phone’s right has hardware controls, where the volume rocker is at the top and a knulled power key sits below it for easy identification.

On the front and back are 13 MP and 8 MP cameras, which have also been carried from the Note 4. They snap good images, and you’ll be satisfied with them for a device that costs less than KES 20,000.

Charging is handled by a microUSB port at the bottom, and the charging process is wicked fast. You can top up the battery up to 80 per cent by the 40th minute, and a full tanks achievable by the 80th minute and that is impressive. Handling this department is a sturdily-built 5V=2A/5A=5A Max charger with solid cable that can last all the way to 2020 when microUSB cables will be old news. I am also glad to see a single speaker grill and a tiny mouthpiece at the bottom. Often, these two hardware pieces are disguised as two grills for symmetry purposes, and it is satisfying to see a separation to keep a consumer’s expectations low. The speaker is loud enough for hands-free calls if blasting phone speakers is your thing.

There is a 3.5mm headphone slot on the top, although I prefer them on the bottom for the longevity of earphones because wear and tear from swinging cables has always rendered the packaged earphones faulty after a couple days of usage. Subjectively, this is an isolated case, but on a big picture, it is a cry for help for Infinix to upgrade the quality of packaged earphones because they genuinely suck.

A crucial hardware inclusion is the XPen. It serves as the major differentiating factor from the Note 4, coupled with the aforementioned premium build. The XPen has several tricks under its sleeve, which will be looked at in a moment. Worth mentioning is that the XPen is powered by the by the phone’s battery via three connecting pins on the handheld’s left side. The stylus is charged via the included case, which offers extra protection and functionality.

It is prudent to note that navigation buttons are part of the phone’s personality that I have found unimpressive. They are capacitive, non-backlit and tiny. See, I use my phones excessively in dark conditions, and the non-lit keys have made that experience horrible. I have no idea why Infinix chose this route. Personally, I would sacrifice a fair section of the display for on-screen buttons because capacitive buttons are that dated. In fact, the Huawei IDEOS from 2010 had backlit keys, seriously. Anyway, my guess is that Infinix wants to squeeze more battery endurance from an already large juicer.

Because the phone is mostly built from a metal slab, antenna lines had to go somewhere, and if you know how Apple’s iPhone 7 Plus took care of them, then you wouldn’t be surprised by Infinix’s implementation.

That aside, the Note 4 Pro takes two SIM cards, coupled with a separate slot for a memory card. As a whole, the handheld tips scales at 196g, and that is something you will immediately notice upon handling it because it is that heavy.

Software Overview and XPen Features

The Pro runs on Android 7.0 with XOS Chameleon skin on top. The skin has been discussed in several of our Infinix reviews, so I’m not going to explore its offering again. However, I will touch on a few aspects that I think are important in this case. First of all is that XOS Chameleon has not removed Nougat features, which is something you cannot say of other Android skins. The settings panel has a hamburger menu for quick access. In-line replies are intact, and so is multi-window support for apps. Other tiny Nougat features such as muting notification prioritization are there too.

The XPen separates this phone from several other large phones in the Kenyan market. Running the show is the XNote app that has two options: Memo and Note. For Notes, you are offered multiple functionalities to annotate your notes. There are up to 9 colour options and a colour wheel for the creative to choose from, a brush option and rubber. Ideally, the stylus has a lot of potential for artists and office people who would love taking notes. On the other hand, Memo is limited to a single colour (black). Also, when the XPen is removed from its slot, a Memo page pops up on the lockscreen for you to write on. Once done, the memo is saved automatically.

XNote app

If you are asking, you can do without the stylus and use your trusty finger, but it wouldn’t be as natural as a physical act of writing.

As I mentioned in the early impressions article, the stylus is housed in the case, although it beats me why Infinix did not find room for it on an already big phone. However, it is forgivable thanks to manufacturing complexities for a phone that targets the midrange segment where price is key.

The leather case feels premium, and has a small triangular window for music controls, flashlight shortcut and notifications.

The device has lockscreen ads! I mean… how and why? Let’s just leave it there.

Camera

The same camera optics on the Note 4 have been carried over to the Pro. On the front is an 8MP shooter along an LED flash for selfies in dingy, dark hallways. The 13 MP on the back is accompanied by a dual-tone LED flash. Both eyes do a fine job, and produce image that are social-media-friendly, so no complaints here. Augmenting these cameras are several shooting modes like panorama, night mode and a basic professional option for tinkerers. You can also capture fullHD video for both snappers.

Here are a two of the many pictures I took for your assessment.

I also noticed that the camera shuts down after 30 seconds of idleness, which can be helpful during accidental pocket presses.

Performance

The spec sheet of this device is identical to that of the Note 4 save for more digital-hoarding room at 32GB and RAM at 3GB. Generally, I found performance to match that of its sibling. Tasks are handled at the same pace, and I expected extra RAM to keep apps in memory for a significant amount of time but I did not notice any major difference. In other words, there are no appreciable performance improvements over the Note 4 for obvious reasons, but that’s fine for a phone with this many tricks at less than KES 20,000. However, light users will be just fine.

Battery Performance

Honestly, the Note 4 has better battery life than the Pro. My intial guess was that a slightly bigger batter (4300mAh versus 4500mAh) was obviously better but that is not the case here as real world usage proves otherwise. On my marathon-ic use, the Pro managed 5 hours of screen on time, which is okay but not class-leading. However, the juicer is big enough to last an entire day of heavy usage, or two days for casual users. You will not be disappointed, but my expectations were thwarted nonetheless.

Other Key Findings

  • The phone gets really warm when charging or when doing intensive tasks. It gets warmer when you are outside in the sun. There is something about black phones and the sun I’m yet to grasp.
  • While the XNote app is a nice addition, it gets overwhelmed by processor inefficiencies because it has crashed on me a couple of times.

  • Mostly, the phone runs just fine, until you give it too many tasks. I squarely pin the blame on the chipset which is just too aged for 2017. People would still buy this device on premium if the CPU were replaced with modern midrange options.
  • The screen is really good at this price, so no complaints here.
  • XCharge should be a standard across all Infinix phone because it is sooo fast.
  • The phone is heavy, and heftier with the case on.
  • Headphone performance is okay, and better than previous Infinix devices. However, the included earphones are uncomfortable and sound like a cooking stove. It is not too late to replace them with something better, so we’ll be patient.
  • XOS Chameleon is nice according to my metrics, but maybe that’s because I use a device with MIUI 8. The only gripe I have with it is its additional apps. Luckily, you can uninstall most them, which is something I did instantly.
  • The Pro is incredibly built, although it is slippery so slap on that case.

Conclusion

This is where we decide whether the phone is worth buying. For KES 19,499 at ecommerce site Kilimall, the Infinix Note 4 Pro is an easy buy because it has no match with an identical set of features like the XPen. Furthermore, the handheld is excellently built with an aluminium back, which is hard to come by for sub-20K phones. Simply put, if build quality and a stylus are important to you, buy it. However, if you need a large phone for media consumption sans solid build or XPen tricks, you will do just fine with the Note 4 that is even cheaper. Just note that performance is going to be the same in all fronts as both devices pack the same hardware specs, mostly.

    The non-lit capacitive keys and the chipset used are the two things that I don’t like in this phone

    • Kennedy Abuya

      Same thing here: navigation buttons that are not not lit is not a lit decision, and nor is recycling chipsets from the past. The phone is build so well it is a shame Infinix had to do this.

  • https://techupdates254.wordpress.com. kfjm254

    Oh my God infinix, quit recycling the chipsets, you’ve used the same 6580 from hot 1 all the way to hot 5, the 6753 from note 2 to note 4 and even worse, used it on the S1, S2 and zero 4! Come on infinix what about us power users? At least use the MT 6750T or helio p-series, that would be awesome! I was an original hot note user, but since moved on to MIUI on a xiaomi (I have a had time explaining to my friends exactly how to pronounce this name) redmi note 3 pro with snapdragon 650. I was hoping this would be my next upgrade, but the chip set, lack of back lit touch buttons and the weight is a turn off. But I like the xpen, and xos 4 a change… hey allan, want a trade in?

    • Kennedy Abuya

      Totally dig how you have noticed that trend. Also, I have a device with MIUI 8 as well (NOTE 4X) and I genuinely do not like it; I mean, performance is okay for a midranger, battery life is epic stupid and it is well put together but the way MIUI ruins things kills my vibe. For instance, I got Nougat a couple of days ago, and basically, it is like I’m running on Marshmallow with a 7.0 on my ‘About Phone’ section. This is why XOS is like stock Android to me.

      • https://techupdates254.wordpress.com. kfjm254

        Yap, I always follow these things. If only infinix would switch the hot series to a 6737 or at least a 6735, the 64bit and 4G connectivity am sure some would gladly upgrade. And the 6753! Die!! The redmi note 4, I hear it’s battery life is out of this world, am jealous.. MIUI is kind of a mixed bag, Anyway, Would you please do an article on using a phone that wasn’t meant for the kenyan market, all the challenges and rewards that come with it, having used one for a year, I know they can be quite serious.

    • joseph mugo

      How could you ever think of ‘upgrading’ from a Xiaomi to an Infinix??Am on the Redmi Note 4 and it’s way Superior to Infinix

      • https://techupdates254.wordpress.com. kfjm254

        It’s all about change, we need to keep changing, I agree moving from a xiaomi with a snapdragon 650, 3GB/32GB isn’t an upgrade, in fact it’s the opposite, but I feel I need a change. The Phone is already a year old and it doesn’t spark that much excitement in me as it used to when it was new..(wtf is wrong with me?). Also am kind of tired of MIUI, it’s too resource intensive and has too much bloatware, of course this could be solved by a rom change,(which I did but reverted after buggy experience and terrible battery and camera performance), but there’s something about using the stock rom that can’t be replaced.

        • joseph mugo

          The Note 4 got an upgrade with it’s SOC…came in in two Variants..MTK and Snapdragon 625..Am on the Qualcomm SOC and I love it..I think MTK devices like Infinix lag behind on performance

      • https://techupdates254.wordpress.com. kfjm254

        Its weird I know, am even ashamed to say it, but after using MIUI and snapdragon for a year, a change isn’t that bad,. I hope

        • joseph mugo

          Yeah,I know.MIUI isn’t the Best kwanza with all the bloatware.Though it’s no different than the XIOS

  • joseph mugo

    For close to 20Gs I’d rather go for a Xiaomi or Oppo device…. though am more of a Snapdragon fan than MediaTek

    • https://techupdates254.wordpress.com. kfjm254

      Snapdragon rules in everyway, performance, battery, ROM support.. You name it. It’s definitely the best. But ata ukizoea pizza itafika place ikuudhi.. That’s were am at, don’t get me wrong, I love this beast. But the prospect of having a galaxy note-like experience, ie 5.7″FHD, and S-pen-ish (x-pen) would be a good trade off. But as I said, due to the chip used, I will definitely be staying away and wait for a better phone to come a long.
