Asus Goes Big on Battery

On this edition of Cell Guru, we bring you tech solutions to all your problems. Amidst the chaos of the demonetisation policy, we find apps that come to our rescue. WhatsApp video calling is rolling out, and we detail the update that's said to be optimised for poor connectivity. Will it beat competitors such as Google Duo? Back to smartphones, we track the all new gigantic Lenovo Phab 2 Plus, and see if it really delivers on its phablet promise. We also review the newly launched Asus ZenFone 3 Max (ZC520TL).
