Innjoo i1s Review: Disruption at the bottom

Posted by

On paper, the Innjoo i1s promises a lot of value for the price. We have had a go with the device and have our Innjoo i1s review ready.

A week ago, I had never heard of the name Innjoo. Today, I am quite a fan. How did that come to happen? It was the combination of Android Kitkat, quad-core processor and price that first caught my attention. It was impossible not to get interested in seeing what a N14,000 5-inch, quad-core processor smartphone would perform. From the moment I first read about the Innjoo i1s, I knew that I had to get my hands on one. A quick run-down of specs:

The packaging is rather lovely: a glossy white box with the brand name embossed in red. Accessories bundled include: USB cable and wall plug. Dazall.

Innjoo i1s Review: HARDWARE AND DESIGN

The Innjoo i1s is made of plastic, yet you will notice that some attention went into the design and finishing. There is a faux metal lining around the sides, giving it a measure of premium looks.

There’s 8GB of internal storage and a micro SD card slot. The display is 5 inches in size, and with a resolution of 480 x 854 pixels, it comes to a PPI of only 196. In real life usage, it isn’t bad. There is no Gorilla Glass and sunlight legibility is poor. Once out in the open, you will need to crank the brightness up to the brightest to be able to use it. It isn’t a stellar display, but it is not that there are any stellar displays at the price range, so it is just fine.

Innjoo i1s Review: SOFTWARE

Innjoo i1s app menu
The i1s runs Android 4.4 Kitkat, which is novel at the price point. That means you are almost bang up-to-date with Android OS. The UI is light on customisation: icons look different from pure Android. I suspect its just a custom launcher baked into the device.

Innjoo i1s Review: CAMERA

Innjoo i1s rear
The 5 megapixel camera on the i1s is a standard 5 megapixel shooter. An LED flash assists with low-light settings, and of course works best within a few metres. Photography in adequate natural lighting is okay, but resolution is not great. It does not belong in the class of the best 5 megapixel shooters.

The camera does have an HDR mode and gives you access to manual controls, so you can tweak if you are a hobbyist. There is a 0.3 megapixel front camera for your selfies and video calls.

Innjoo i1s Review: MULTIMEDIA

There is a pre-installed Music player and Video player. Media playback for both is standard fare for budget level phones. The loudspeaker is mono and adequate. Using a headset gets you better audio, which is almost a given across most devices.

Innjoo i1s Review: NETWORK, CALLS & INTERNET

Innjoo i1s SIM slots
The i1s is a dual SIM phone, with both SIM slots being the Mini SIm standard. That’s the normal SIM card type. The i1s holds on to network signals fairly well.

You can pick what network to use for calls and SMS, or set it to ask you each time you initiate a call or want to send out a message. In call, the microphone and earpiece speaker sometimes come across as weak. Using a Bluetooth headset, I got better audio quality during my telephone calls.

The i1s offers 3G/3.5G internet and you can determine which of either SIM cards is pegged to 3G.

WiFi is here, and the phone can be used as a WiFi hotspot too.


Performance-wise, the Innjoo i1s is impressive. Powered by a 1.3 GHz quad-core CPU and 1 GB of RAM, I needed to know how it performs. So, I pitted it against some of the finest mid-range quad-core Android smartphones, and it performed quite admirably, beating back the Motorola Moto G, Huawei Honor 3C and LG L90 D410.

Here are its raw benchmark results:

  • AnTuTu Benchmark: 17,998
  • Quadrant Benchmark: 8,619

I am not an app junkie: I install only what I need. I have 26 apps installed on the i1s, and it runs fairly smooth. It isn’t flagship smooth, but then you weren’t expecting that from a device squaring off in the low to mid range arena.

I did run into a problem that is common to budget devices: the allocation of internal space to applications is very small – a mere 0.89GB. So, very soon I ran out of storage space for applications. While I was able to move some apps to SD card, I finally hit that point where there are no more apps to move to SD card and the phone keeps returning an insufficient space error when I try installing some large apps. I wouldn’t hold this against the i1s, except that it has memory specs similar to the Moto G, Honor 3C and L90 D410, and none of them gave me those issues when I reviewed them.

Innjoo i1s Review: BATTERY

Innjoo i1s battery

The i1s has a removable 1900 mAh battery. I had fears that this would be a weak spot off the i1s, as it is for most budget smartphones. I was not wrong. If you are a heavy user, you will need to plug in the i1s at least twice a day. Sometimes thrice.

My regular use case scenrio: active WiFi connection, two active SIMs, light to moderate phone calls, two email accounts, Twitter, Facebook, Google+ and Instagram synchronising and in use, BBM and WhatsApp active, and moderate web browsing. With this scenario, the most I could squeeze out of the battery was 7 hours and 41 minutes. Many times, I got significantly lower.

Fairly moderate users can get by with plugging in twice. In my opinion, you will need a power bank as a companion to the i1s. Battery certainly isn’t this device’s strongest point.

Innjoo i1s Review: MISCELLANEOUS

Default keyboard is Google keyboard. I simply installed the new Android L keyboard with “Material” design and I lived happily ever after. That keyboard is much better than the current Google keyboard.

There is a pre-installed file manager and Battery Doctor.

Innjoo i1s Docs To Go and Amazon Store

Docs To Go is also pre-installed for managing Office documents. However, when I launched it, it threw up an error about Amazon Appstore being required. The app wouldn’t run without Amazon appstore. Bummer. However, there are plenty of free Office editors available in Google Play, so no worries. But I wasn’t able to download any because of the earlier mentioned insufficient memory issue.

Innjoo Store

Innjoo has its own store, Innjoo Store, that comes pre-installed on the i1s. This is in addition to Google Play on the device. Innjoo says on its website that it plans to make money off services and not from selling hardware, which explains the price of this device. The Innjoo Store offers app downloads, app updates, automatic updates, and a download manager. I haven’t figured out what extras it brings to the table beyond what Google Play does.

Innjoo i1s Review: CONCLUSION

Innjoo i1s presented
The InnJoo i1s is incredible value for money. It is a combination of entry level and mid-range features at a price point that no-one can argue with. It beats every other Android smartphone at the same price point and outdoes many other mid-range Android smartphones. All for the price of an entry level Android smartphone.

No; I am not just happy with the InnJoo i1s. I am very impressed at what has been pulled off here. And yes; I heartily recommend it if you are shopping for a sub-N15,000 Android smartphone. It is incredible value for money.


  1. I Did Run Into A Problem That Is Common To Budget Devices: The Allocation Of Internal Space To Applications Is Very Small – A Mere 0.89gb

    Well, It Appears Not Only Budget Devices Are Afflicted With That Ebola Virus. My Tecno Phantom A Iii Certainly Is Culpable, Here, Too..

    Or, Perhaps, We Could Regard The Tecno Phantom A Iii As Budget.

    Default Keyboard Is Google Keyboard. I Simply Installed The New Android L Keyboard With “material” Design And I Lived Happily Ever After. That Keyboard Is Much Better Than The Current Google Keyboard.

    Well, Nations Have Gone To War For Far Less Irreverence, And Android Lord Harry Echemco Would Surely Come Out, Guns Blazing, For Such A Rambunctious Statement. Google Keyboard Is The Eldorado, For Him. //

    If This Device Is Any Indication If What To What Is Likely To Be A Trend Regarding The Smartphone World (Making Money From Just Services, Rather Than The Hardware), Then The Big Boys (Indeed, All) In The Smartphone Hardware Market.. Would Need To Go Back Their Strategy Tables

    As Always, The Only Concern For Purveyors A New Entrant Like This, Is, How About After Sales Service? I Get A Cracked “Injure” Smartphone, Can I Get It Fixed Expeditiously?

  2. By the way, it’s been long I read a well rounded review of an Android smartphone from Mr. Mo. Impressive! I think every bit of the most revenant areas are covered. I’m surprised that Mr. Mo will be running out of memory of this device given its 0.890GB of internal storage that’s dedicated to apps installation and the fact that we know he’s not an app junkie.

    Default keyboard is Google keyboard. I simply installed the new Android L keyboard with “Material” design and I lived happily ever after. That keyboard is much better than the current Google keyboard.

    The Android L keyboard is quite pleasing to the eyes but it’s just either as capable or less capable than the original Google Keyboard. I have it installed as an app too but I prefer sticking to the official Google Keyboard because it appears to be more functional and I just want that demarcation of the individual keys

    Nothing really to go to war for especially as I know that ever since the demise of Symbian, Mr. Mo has switched from being the function driven smartphone user to the candy and chocolate type provided the his very basic needs are met, the reason for his gravitation to less functional Windows Phone.

  3. “I Did Run Into A Problem That Is Common To Budget Devices: The Allocation Of Internal Space To Applications Is Very Small – A Mere 0.89gb”


  4. Is it true that innjoo i1s is only available on jumia online shopping, that no other retailer will sell the phone in Nigeria.

  5. Please just heard about this Innjoo i1s, just need honest advise which is better Innjoo i1s or Techno p5.


    P’S. Am a lady who just need a good budget phone with good functions.

  6. The Innjoo i1s is way better than the Tecno P5. If your choice is a 5inch phone, pick it. Or if you’re sticking with a 4″ phone, Tecno F5 is a better option

  7. @Mila, in addition to what Elroy Chibex has said, most people would never believe The InnJoo i1s/i2 is a budget device because of its mid-level to premium look and feel.

  8. I’m currently using the innjoo i1 phone and it has been smooth sailing so far. With regards to the memory space you could get an SD card max 32G to support. My main concern though is after sales service; if commitment is shown to consumers through after sales service then i guess the new found relationship will work out pretty fine.

  9. I must commend you for the astonishing review on innjoo 1s as it turns out the full-proof pro and cons of the devise.I am a man that never compromises with objectivity and I can judge you faithful in that regard.Well done,as you have just gotten a fan.
    But then,I will like to know your trusted and tested opinion about rooting the phone.
    thank you
