Does your phone's battery die too quickly? Are you sick of lugging around a power pack to top up your phone throughout the day? Well, HMD Global has announced the entry-level Nokia 2 phone which the Finnish company says will last for two days on a single charge off its massive 4,100 mAh battery. It also features a Qualcomm Snapdragon 212 quad-core processor, a 5-inch 1280x720 LCD, an 8 megapixel rear camera and 5 megapixel front camera, 1GB of RAM, and 8GB of internal storage which is expandable to 128GB with a microSD card.

"Every component of the Nokia 2 — from the display to battery, chipset to system design — has been engineered to draw as little power as possible from the huge battery," said Juho Sarvikas, chief product officer at HMD Global.
