Karbonn Titanium Jumbo

The latest entry-level Titanium-series smartphone from the domestic smartphone maker Karbonn is the Titanium Jumbo. The major highlight is the big battery and hence the name. The device features a polycarbonate plastic back panel which is topped with rounded edges on all sides making it easy to hold.
For image lovers, there is a 13-megapixel rear shooter and an 8-megapixel front-facing camera which can be used to capture images, record videos, take selfies and make video calls. Also, the device sports a dual-LED flash at the back to help you out in dark conditions.

The Karbonn Titanium Jumbo ships with a 5-inch HD IPS display which is bright and has decent colour reproduction. However, one has to struggle while reading the screen under bright sunlight.
Under the hood, the smartphone is powered by a 1.3GHz quad-core chipset and 2GB of RAM to ensure seamless performance.

The device also ships with a free back cover which is included in the box, and it is expected to compete with the Redmi 4 from Xiaomi.

The Karbonn Titanium Jumbo runs the Android 7.0 Nougat operating system out of the box and packs a non-removable Li-Po 4,000mAh battery that is claimed to deliver a standby time of up to 400 hours, and talk time of up to 16 hours.

For installing apps and storing music, videos or images, there is 16GB of onboard storage which as per your requirements can further be expanded up to 64GB via a microSD card.
Connectivity options on the smartphone include 4G with VoLTE support, GPS, Bluetooth 4.0, Wi-Fi 802.11 b/g/n, and a microUSB 2.0 port.
