Expert Review


The Karbonn Titanium Jumbo is a good low-end budget smartphone. This device gives a lot of value for money. We get a well-built metal body with a bright display, good set of cameras and awesome battery life. The OS also looks modern and fresh. The overall performance is on par with most of its peers in this category. Although, we would have liked a better chipset for sure. Also, we do not get fast charging support and fingerprint sensor but both are very rare in this category as well. You can surely go for the Karbonn Titanium Jumbo smartphone if you want great battery life and decent overall performance. If you want to check out the competition, then take a look at the Xiaomi Redmi 4, Moto C Plus and Xolo Era 2V.


Karbonn Mobiles had launched the Titanium Jumbo smartphone back in October 2017. It is a budget phone that focuses on battery life. The main USP of this device is its 4000mAh battery that promises up to 400 hours of standby time and 16 hours of talk time. We also get decent hardware and software in this phone. So let us find out in our Karbonn Titanium Jumbo review if it is worth the money or not. However, do check out the specifications of the mobile below.

The Karbonn Titanium Jumbo is powered by a 1.3GHz quad-core processor, coupled with 2GB RAM and 16GB internal memory (expandable up to 64GB). 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 13 megapixel primary rear camera along with a 8 megapixel selfie shooter. There is Dual SIM connectivity along with 4G VoLTE support. Others include 3G HSPA+, WiFi 802.11 b/g/n, Bluetooth 4.0 and GPS. Under the hood, there is a 4000mAh non-removable battery. In the sensor department, we get accelerometer, gyroscope, ambient light and proximity sensor.

Design & Display:

The Karbonn Titanium Jumbo is made up of polycarbonate but it completely looks like a metal body from far away as it has a metallic paint job. The build quality is very good and hence the device looks premium despite of rocking a plastic body. The phone is quite compact but is on the heavier side (172 grams) due to the massive battery under its hood. You will get used to the weight over time and can easily use it with one hand for long duration without feeling any pain in your palms. The edges are slightly curved and hence the grip is good. The back cover has a matte finish with glossy paint. It has large bezels on top and bottom of the display.

On the front, we get a 5-inch display along with the selfie camera, LED flash, LED notification, couple of sensors and earpiece. There are three capacitive buttons below the display for navigation and they are backlit as well. The volume rocker and power/lock buttons are placed on the right side of the phone, while the left side remains empty. The microUSB port and the 3.5mm audio jack sits at the top. There is nothing at the bottom except the primary microphone. Turning towards the back side, we get the primary camera at the top followed by the dual LED flash on its right. The Karbonn branding is found below the camera in the middle while the loudspeaker is located at the bottom. Upon opening the removable back cover, we get a 4000mAh battery (non-removable) along with SIM card slots and a dedicated microSD card slot. Overall, the Karbonn Titanium Jumbo has a good ergonomic design and build quality.

The Karbonn Titanium Jumbo features a 5-inch IPS display, which comes with a resolution of 1280 x 720 pixels (HD). It is a generic display in this price segment but we get a good display for high-definition content consumption. The color saturation is neutral, brightness and contrast levels are good. The viewing angles are decent and sunlight legibility is also moderately good. The texts, images and video look vivid and crisp. Since the phone comes with an ambient light sensor, the brightness automatically gets adjusted according to surroundings. We do not get any branded protection on top of the screen but there is a layer of glass which protects the display from daily wear and tear.

The touch response of the phone is quite good mainly because of the good display quality and fluid interface. Overall, the Karbonn Titanium Jumbo has a good display that is tailor-made for content consumption.


The Karbonn Titanium Jumbo is powered by a quad-core processor clocked at 1.3GHz and 2GB RAM. Karbonn Mobiles have not mentioned about the chipset manufacturer but it might be from the house of Spreadtrum. You can perform most of the basic day-to-day tasks easily without any lag or stuttering. Although, there was a little bit of lag while running high-end apps and games. The 2GB RAM onboard provides a good multitasking experience and you can run more than five apps in the background simultaneously. The UI is mostly stable and does not show any performance issues. In terms of gaming, you can play most of the high-end games but they will run in basic to medium settings. The Karbonn Titanium Jumbo comes with 16GB of internal storage, out of which you will get around 9GB of free space. However, you can increase it up to 64GB by adding a microSD card. We do not get a fingerprint sensor in this phone.

Talking about connectivity, there is 4G VoLTE support along with Dual SIM (micro) connectivity and both the slots support 4G but not simultaneously. The Titanium Jumbo comes with a massive 4000mAh battery under the hood but it is non-removable. You will easily get up to two days of battery life with moderate usage. It gives around two weeks of standby time and up to 15 hours of talk time. However, there is no fast charging support and hence you have to spend around three hours to charge it from 0-100.

Overall, the performance of the Karbonn Titanium Jumbo is good and the phone feels quite nippy.


The Karbonn Titanium Jumbo packs in a 13 megapixel primary camera at the back. It is a very good shooter in outdoor conditions with bright light sources. The images look crisp and vivid. We get a lot of details in these shots and the color saturation is also neutral. However, the low light images have some noise and grain and they lack details as well. So we would advice you to shoot in optimal light or use LED flash. The focusing mechanism is moderately fast but is not very accurate, specially for moving shots. HDR mode gives a decent amount of dynamic range while macro shots look good with bokeh effect. Now coming to the front-facing camera, we get a 8 megapixel shooter and it can click good selfies. They may not be the best in class but they are quite good and packs in beauty modes along with lot of live filters and effects.

The camera app of the Titanium Jumbo is very easy to use as it has a simple interface. We get a couple of shooting modes in the stock camera app but we would suggest you to stick with the Auto Mode. The primary shooter can only record Full HD videos and the quality is quite satisfactory. Overall, the camera department of the Karbonn Titanium Jumbo performs well, specially in outdoor conditions with natural lighting.

Audio & Video:

The machine drilled speaker holes of the Karbonn Titanium Jumbo are located at the bottom on the back side. The loudspeaker sounds moderately decent and it is loud as well. There is no audio distortion, even at the highest volume levels. Since the speaker is located on the backside, the sound gets muffled when the phone is kept on a flat surface. It is a common problem for all smartphones having speaker at the back. We get a native music app and it comes with all the necessary features for an optimal audio experience but you can download apps like Saavn to stream online music.

The Karbonn Titanium Jumbo can play or stream HD or Full HD videos with ease but do not expect it to run 4K videos. We get a bundled earphone but it is very average in terms of build and sound quality. So we would advice you to use a good earphone for a good audio experience. Overall, the audio and video quality of the Karbonn Titanium Jumbo is moderately good.

Software & Ui:

Out of the box, the Karbonn Titanium Jumbo smartphone runs on Android 7.0 Nougat OS. It is the second latest OS right now as we already have Android 8.0 Oreo OS in the market. However, all budget smartphones are running mostly on Nougat OS and thus Titanium Jumbo has the latest one. Also, we do not expect it to get Oreo update ever as it is a low-end smartphone. Now talking about the interface, it feels very decent and we did not face any lag and frame drops in our normal day-to-day usage. This is basically due to 2GB of RAM. There was slight stuttering while playing games or running high-end apps and that is expected in a low-end Android phone. We got a stock Android experience as Karbonn Mobiles have not added an extra layer of custom UI on top of Android OS. There are a couple of pre-installed apps (bloatware) but you can easily uninstall them if you do not use them. You can even install a third-party theme such as Pixel Launcher or Nova Launcher to get the latest Android look and feel.

Overall, the UI of the Karbonn Titanium Jumbo is quite fluid and feels mostly like stock Android.
