The Infinix Note 4 and the Note 4 Pro are the latest addition to the brand’s Note series. Both devices were exclusively launched on the 3rd of July, 2017.

Before it’s official launch, the rumored device specs and features had surfaced online. The outstanding feature I looked forward to, was the X-Pen. Other than that, the device having a somewhat similar design to the latest Samsung Galaxy devices was although not exactly innovative, it seemed cool.

Infinix are beginning to take the bull by the horns as the year goes by, I said to myself. Still before the official launch, Mobility Arena had reported a leaked specs said to be originally by Android headlines. The specs states 6GB RAM and I got more fascinated.

Now to the deal day, I was invited to the official launch event which I attended. There and then, it was disclosed that the infinix Note 4 will be available in two variants (excluding the Pro); a 2GB RAM version, and a 3GB RAM version.

The Infinix Note 4 Pro (making three devices in all) gets the newest specs. A preview of the device specs at the event, it was said that the device features a curved metallic back pack. You know I have a flair for metallic designs, yeah?

Fast forward to when the device became readily available, things didn’t seem like I expected. How? Let’s move on. But first, let’s look at some spec-sheets.

Having the Infinix Note 4 x572 key specs out of the way, let’s look at the key specifications of the Note 3 x601.

Now, having cleared off the key specifications of both devices, what’s new?

After one year (almost one year actually), What’s new from the specs-sheet would be a smaller inch sized display (same resolution), design, front facing camera, and battery. That’s all that seem new, at least, to me. Except for the Note 4 pro of course.

Both devices still have a handful of key features. Same processor, RAM, back camera amidst others.


In terms of display, the Note 3 features a 6.0inch display with FHD resolution while the Note 4 features a 5.7inch with FHD resolution. So technically, you should expect a better PPI on the latter.


Remember I said it was stated at the event that the device feature a curved metal back pack? Well, the Note 4 back pack isn’t metal. Although it looks like it, it isn’t. The metallic design only applies to the Note 4 Pro.

Infinix note 3 designs

The build is actually poly-carbonate. In layman’s term, the Infinix note 4 design is plastic. Let’s call it, curved plastic. Personally, plastic design on a smartphone in 2017 is a flaw. The Note 3 on the other hand, features a metallic design.


The Note 4 still features a 13 megapixels back camera. What’s new however, would be an 8 megapixels front facing shooter. The Note 3 features a 5 megapixels camera. Would you term that as a major difference?


When the Infinix Note 3 was launched, it was said that the device battery with just 5 minutes charge, can last up to 200 minutes talk time.

This time, infinix is saying with a 5 mins charge on the Note 4, the device can last up to 250mins talk time. Looking from the specs-sheet, the Note 3 features a bigger battery. However, based on what the brand said, the Note 4 charges faster.

So, Is The Infinix Note 4 Worth The Upgrade From The Note 3?

Frankly, if you are using the Note 3 and you feel inclined to upgrade to the Note 4, you ain’t exactly out of place.

However, if you are using the Note 3 Pro, an upgrade is definitely not worth it.

Personally, the only device worth upgrading up (if necessary), is the Infinix Note 4 Pro. What’s new in that regards, is the X-PEN, a metallic body design, a bigger internal storage, with a 4500 mAh battery. You see?

Over to you. What do you think? Is it Worth upgrading from a Note 3 to the Infinix Note 4?


  1. I use a note 3. What would have been worth upgrading to is the 4G connectivity. That’s not something that’s fully effective in Nigeria, yet.

    Lemme kuku be managing my phone for now until an upgrade is well worth it.

    Nice one, Sammy!
