Here's an in-depth look at what made the Celkon S1 a considerable option during its time.

Design and Build

The Celkon S1 boasts a sleek and slim design with dimensions of 144 x 71 x 8.9 mm and a weight of 137 grams, making it comfortable to hold and carry. The device was available in a classic black color which added to its elegance. It featured a dual SIM capability, catering to users who want to manage personal and professional contacts efficiently.

Display

The smartphone came with a 5.0-inch IPS LCD display with a resolution of 1080 x 1920 pixels, translating to a pixel density of approximately 441 ppi. This ensured that visuals and text appeared crisp and clear, making it a good option for media consumption. The screen-to-body ratio of around 67.4% meant that users could enjoy a decent amount of screen space without excessive bezels.

Performance and Software

Under the hood, the Celkon S1 was powered by a quad-core 1.5 GHz processor. It operated on Android 4.2.1 Jelly Bean, which was a popular OS version at the time. With 1GB RAM, the phone offered smooth performance for most standard applications, although it may struggle with more demanding apps and multitasking due to the limited RAM.

Storage

For storage, the device came equipped with 16GB of internal memory, which was ample for housing essential apps and media. Additionally, it offered a dedicated microSDHC card slot, allowing users to expand their storage capacity and store more data, apps, and media files.

The Celkon S1 was geared with a 13 MP primary camera, complete with autofocus and an LED flash, facilitating decent quality photography even in low-light situations. Furthermore, for selfie enthusiasts, the phone was furnished with an 8 MP front-facing camera, providing respectable quality for video calls and selfies.

Battery Life

The device was powered by a Li-Ion 2300 mAh battery, which provided enough juice to last a full day on moderate usage. This was typical for smartphones of that era and provided users with flexibility without the constant need to recharge frequently.

Connectivity

In terms of connectivity, the Celkon S1 supported GSM/HSPA networks and had provisions for Wi-Fi 802.11 b/g/n, Bluetooth 4.0, GPS and a microUSB 2.0 port for charging and data transfer. However, it did not include NFC capabilities, which might be a disadvantage for users interested in contactless payment options.
