Expert Review


The Intex Aqua Lions E3 is a decent entry-level budget smartphone for first time smartphone users. You are getting a good display, solid build, decent hardware, fluid interface and good overall performance. The cameras are good and the battery life is decent. However, we do not get fast charging support, fingerprint sensor and gyroscope. These are mostly absent in this price range but still you can find some of the features in a couple of phones. So if you want a decent smartphone, then go for the Intex Aqua Lions E3 or else take a look at the Redmi 5A, iVooMi Me3 and Yu Yunique 2.


Intex Technologies launched the Aqua Lions E3 smartphone in India back in March 2018. It is a low-end budget smartphone made up of polycarbonate. However, it does possess a solid HD display along with modern connectivity and software. So let us take a look at the Intex Aqua Lions E3 review to find out if you should purchase this budget smartphone or not. However, do take a closer look at the specifications of the device first.

The Intex Aqua Lions E3 is powered by a Spreadtrum SC9832A quad-core processor, coupled with 2GB RAM and 16GB internal memory (expandable up to 32GB). The phone sports a 5-inch HD display and runs on Android 7.0 Nougat OS out of the box. In the camera department, we get a 8 megapixel primary rear camera and a 5 megapixel selfie shooter. There is Dual SIM connectivity along with 4G VoLTE support. Others include WiFi 802.11 b/g/n, Bluetooth 4.0 and GPS. In the sensor department, we get a magnetometer, proximity and ambient light sensor. Under the hood, there is a 2500mAh non-removable battery.

Design & Display:

The Intex Aqua Lions E3 is made up of polycarbonate. It looks very basic and the design is ergonomic. It is a compact smartphone with good build quality. The plastic quality is not very tacky and hence the phone feels good in hands. The phone can easily be used with one hand and for long period of time without any pain in your hands. It is quite slim (8mm) and does not weigh (154 grams) too much. The edges are slightly curved. It has a matte finish at the back and hence the phone does not slip out of the hand easily.

On the front, there is a 5-inch display along with the selfie camera, earpiece and couple of sensors. We get three capacitive buttons below the display for navigation but they are not backlit. The volume rocker is on the left while the power/lock button is on the right. The microUSB port, primary microphone and loudspeaker are found at the bottom while the top houses the 3.5mm audio jack. Turning towards the back side, we get the primary camera along with the LED flash on the top middle. The Intex branding is found below the camera. The back cover is made up of plastic and is removable. Upon removing the cover, you can find the 2500mAh battery along with the SIM and microSD card slots. Overall, the Intex Aqua Lions E3 has a good build, ergonomic design and decent hardware.

The Intex Aqua Lions E3 rocks a 5-inch IPS display, which has a resolution of 1280 x 720 pixels (HD). It is a very basic and generic display in this category but it does a very good job. The display is meant for content consumption and hence you can enjoy videos and games on it. The colors look natural, bright, vivid and crisp. However, it obviously does not look as good as a Full HD screen but the viewing angles are quite good and sunlight legibility is decent as well. Since it comes with an ambient light sensor, you do not have to adjust the brightness manually according to the surroundings. There is an added glass protection on top of the display but Intex has not mentioned any brand name. Thus, it might be an unbranded glass but it does protect it from daily wear and tear. The touch response of the Lions E3 is quite smooth because of the good quality display and fluid UI. Overall, the Intex Aqua Lions E3 has a good compact and vivid display.


The Intex Aqua Lions E3 is powered by a quad-core Spreadtrum SC9832A processor clocked at 1.3GHz and 2GB RAM. Like any other low-end budget smartphone, the Lions E3 can also handle most of the basic day-to-day tasks without any hiccups. The 2GB RAM onboard provides an above par multitasking experience and it can also handle most of the normal apps and casual games. The interface is quite smooth throughout but there were some hiccups while using high graphics intensive apps and games. When it comes to gaming, you can easily play the casual games but it will be a struggle to play the high-end graphics intensive games. The Intex Aqua Lions E3 comes with 16GB of internal storage, out of which you will get around 11GB of free space. However, if you want more storage, you can get that by inserting a microSD card (up to 32GB). Also, you do not have to sacrifice on a SIM slot as it comes with a dedicated microSD card slot. There is no fingerprint sensor on this phone.

When it comes to connectivity, we get 4G VoLTE support along with Dual SIM (micro) but only the first slot supports 4G while the second slot only supports 3G. The battery capacity of the Lions E3 is 2500mAh, which is a standard size in this segment. It does not support fast charging but it also does not take a very time in getting charged from 0-100. You will get around one day of battery life with moderate usage.

Overall, the Intex Aqua Lions E3 is a good performer in most departments.


The Intex Aqua Lions E3 rocks a 8 megapixel primary rear camera. In terms of image quality, the pictures clicked in bright outdoor conditions look good and offer a lot of details. The colors look natural and are not very over saturated. However, the low light performance is not the best as we get a lot of grains and noise. Hence, we would suggest you to use the LED flash in low light environments or just use optimal lighting condition to click pictures. The focusing mechanism is not the quickest but it is quite accurate. HDR images had a lot of dynamic range and it is the best mode for landscape pictures as well. However, macro images had little amount of background blur. Now coming to the selfie camera, we get a 5 megapixel shooter and you can click pretty good selfies. There are also filters and beauty mode to enhance those selfies.

The camera app of the Lions E3 comes with an intuitive and simple interface, that can even be used by novice smartphone photographers. There are a couple of shooting modes in the stock camera app but for better performance you should install a third-party camera app like Google Camera. The primary shooter can record HD videos and the quality is average. Overall, the Intex Aqua Lions E3 does come with a good set of cameras but they are not the best in the segment.

Audio & Video:

The machine drilled speaker holes of the Intex Aqua Lions E3 are placed at the right bottom. The loudspeaker is audible and the audio quality is good. The volume does distort a bit at the highest volume levels. Since the speaker is located at the bottom, the sound gets muffled by your palms when you play games or watch videos holding the phone in your hands. There is a native music app but it does not have a lot of features and thus for the best audio experience, you can download a third-party app of your preference. A bundled earphone comes with the device but it is below average in quality. So we would suggest you to purchase a decent pair of earphones.

The Intex Aqua Lions E3 can play HD videos smoothly but it does lag a bit when it plays Full HD videos, however it certainly cannot play 4K videos. For the best video watching experience, just download a third-party app like MX Player. Overall, the Intex Aqua Lions E3 gives decent audio and video output.

Software & Ui:

Out of the box, the Intex Aqua Lions E3 smartphone runs on Android 7.0 Nougat OS. It may not be the latest OS in the market but it is good enough for an entry-level smartphone. However, do not expect to get any major Android OS update in the future as most budget smartphones do not get any. The interface is quite smooth and we did not notice any lag or frame drops in normal day-to-day usage. Most popular apps and games started quickly as well. The UI gives a stock Android like experience because Intex did not add an extra layer of custom UI on top of Android Nougat OS. Most important Nougat features such as Doze are also available here. There are a couple of pre-installed apps (bloatware) but you can easily uninstall them if you do not want to use them. In case you do not like stock Android like interface, then just download any third-party theme of your choice to change the look and feel of the interface.

Overall, the Intex Aqua Lions E3 comes with a lag-free interface based on a relatively new Nougat OS.
