Expert Review


The Lyf C451 is one of the many entry-level phones to flood the market, it does offer decent performance, acceptable camera performance in daylight, a good build quality, and design. It comes with close to a stock Android interface which is a good thing for first-timers, and 1GB of RAM in this budget is a bonus. On the other hand, there are a fair number of flaws as well, like the poor display resolution; terrible low-light camera performance is some of the drawbacks. Though they are not much off disadvantages considering the price range, we had to include them. So, if Lyf branded phone at this price is your requirement, you can go for the C451, if not there are Intex Lion series phones, investing a Rs. 1,000 more will get you a Redmi 4A which try to fill the shortcoming of the Lyf C451 to an extent.


Reliance didn't stop with just Jio it even launched the Lyf brand in India as well to offer better value for money smartphones in the budget segment. Though they aren't the top sellers of some sorts, they still are a decent offering especially in remote and areas where the online reach is limited. To carter every segment audience, Reliance has launched the Lyf phones in every price range starting from entry-level to mid-range segment. For today, we will restrict ourselves to the entry level Lyf C451 device which is priced at Rs. 4,999 and supports all Jio suite apps as well. Let's see if this entry-level phone from Jio is the best phone that you can worth considering giving up your current feature phone.

The device sports a 4.5-inches FWVGA (480x854 pixels) display and is powered by the Qualcomm Snapdragon 210 SoC clocked at 1.3 GHz Quad Core Processor with 1GB RAM and 8GB internal storage that is further expandable up to 128GB. The Lyf C451 runs on Android 6.0.1 Marshmallow out of the box. In the camera department, the device packs a 5-megapixel rear camera and a 2-megapixel front camera on the front. Connectivity features include 4G VoLTE, WiFi, Bluetooth, GPS, Dual SIM. A 2,800mAh battery runs the show behind.

Design & Display:

Now if you are moving from a feature phone, the Lyf C451 has a good design for starters. It has a typical candy bar design with all plastic build that fits perfectly in hands, thanks to the compact size. The edges are curved with a smooth finish that doesn't hurt your hands even after extended usage, the frame running around the four corners has gold coloring to it offering dual color contrast, giving the plastic build a consolation. We weren't expecting a great design or metal build at this price, but we did like what Reliance had to offer with the Lyf C451.

Moving to the placements, the front houses the 2-megapixel camera, sensors, and down below there is a physical home button accompanied with two capacitive buttons that aren't backlit making it harder to use in dark conditions. The 3.5mm audio jack is present on the top, while the microUSB port is present on the bottom along with the primary microphone. Flipping it, you will find the 5-megapixel rear camera, LED flash, Lyf branding, and speaker grills. The back panel is removable giving you access to the removable battery. The power and the volume rockers can be found on the right, while there is nothing present on the left side. Overall, quite a decent design in this price range, and expecting more in this price segment is a lot.

The device sports a 4.5-inches FWVGA display and the screen is an IPS panel. It isn't a 720p panel or a qHD panel either; it is a FWVGA panel which is what you will get at this price. Thanks to the IPS panel, the viewing angles are good, but on extreme tilting, you can notice a hint of bluish hue that can get annoying while playing games or watching videos. However, the touch response is smooth, and even the colors look decent. There isn't any oversaturation of RGB colors especially while watching videos or clicking pics.

The brightness levels are our major concern here, viewing the display outdoors or while under board daylight was a bit tough considering the poor resolution of the screen. That said, you can't expect a better quality at this price either. Overall, for what it is, the Lyf C451 has a decent quality display and should suffice the needs at this budget.


It is powered by the Qualcomm Snapdragon 210 SoC clocked at 1.3 GHz Quad-Core processor with 1GB RAM. For casual to moderate tasks like making phone calls, sending messages, browsing the internet with 1-2 chrome tabs, checking social media updates, the device, for the most part, handles smoothly with minute lag occasionally. On the flip side, it can’t handle too much pressure or heavy multitasking. It dropped frames and felt sluggish when just 3-4 apps are actively running; we had to close the apps for the device to use the device smoothly again. This is mainly due to the age-old chipset that fails to cope up with current apps that require more hardware to function properly. But then again, entry-level phones are mostly meant for casual to moderate tasks.

In the gaming department, the Lyf C451 was able to play games like Temple Run 2, Riptide GP2, Subway surfers without any issues and the frame drops were very rare as the games we tried aren’t high on graphics. Overall, the performance of the device suffices the needs of a moderate user; you would be at blame if you were to expect massive performance.


The device packs a 5-megapixel rear camera and a 2-megapixel front camera for selfies and video calls. The images are okayish with acceptable colors, and fine details given that you are clicking in bright and daylight conditions. There is an HDR mode that brightens the images and intakes more details. The close-up shots don't offer much regarding picture quality, but the landscape shots as mentioned above do turn out decent at this price range. In the low-light, the output is outright terrible with complete dark pictures and washed out colors. Though there is LED flash, it doesn’t help much except for overly brightening and spoiling the pictures. The rear camera can record 480p SD videos, and the output is shaky and noisy for our liking.

The front 2-megapixel is meant for selfies clicked in bright surroundings and low-light. We did find the images clicked outdoors to be decent, but indoors and artificial shots are a lost cause and it feels like it is there just for the sake of it. Overall, the camera department is neither a disappointment nor satisfaction. For the price, it does fare well in good lighting and outdoor conditions.


There is a 2800mAh battery that is removable and no fast charge support either. The battery has to be one of the best aspects of the phone. With typical moderate to casual use, the device can easily last an entire day. Our usage includes social media updates, listening to music, playing games for 30-40 minutes, taking calls, sending messages, and with kind of usage, it was able to last an entire day. However, on heavy usage, it drains quicker than expected. The Idle battery drain is minimal, but on continuous usage, the device consumes the battery significantly faster than it should which is a bad thing.

As there is no fast charge support either, it takes close to 3 hours to charge it entirely from 0-100%. Given the price range, we wouldn't complain much about the charging speeds. Overall, if not for the slight battery drain while heavy usage, it is a good battery and easily lasts an entire day.

Audio & Video:

At this price, we weren't expecting earphones in the box and much to our surprise, the company has bundled in-ear style earphones within the box. The sound quality via them is clear and loud. There was no distortion of audio even with maximum volume. The speaker grills are present on the rear side makes a difference while listening or watching videos via the speaker. The audio gets muffled with either your hands or flat surface. Other than that, the sound quality is excellent.

Moving to the video department, it could play 480p SD quality videos given the low screen resolution. We tried to play with the default music player, but specific formats were unsupported. Hence, we had to install MX Player which then played smoothly. Overall, the entertainment department to does well, but don’t expect it to play 720p HD videos.

Software & Ui:

The reliance lyf c451 runs on android 6.0.1 marshmallow with close to stock android. We have few bloatware apps apart from the google and Jio suite apps, and these pre-installed can’t be uninstalled without rooting the handset. The Stock Android software has very little to offer in terms of customization, but then again Android is an open operating system, you can rely on Play Store apps for theming.

There is an app drawer icon, and all the apps are present under it. Being a company that is very new to the smartphone segment, there is promise for future software updates. The settings app and notification style is also stock, and nothing much is being tweaked here. It comes with 1GB of RAM out of which close to 500MB is available when just default apps are running in the background. The free RAM helps running apps and keep the multitasking smooth to a certain extent. Having said that, once you push the device to its maximum limits, it will slow the device and lags in responding as well. Overall, the software and multitasking are decent enough, but you will have to clear the background running apps to keep the device performance smooth.
