I am at work for 9 - 10 hours. I have Lyf wind 6 with LTE on all the time. I have Bluetooth tethered it to my OnePlus One. By the end of the day I have Over 50 % remaining in my Lyf mobile. This is more efficient than Wifi hotspot. Only disadvantage is due to Bluetooth, speeds are limited to 1.5 - 2 Mbps. I mostly use WhatsApp, FB, Twitter and Reddit during the day, so it works best for me.
I have heard some guys saying in Twitter that Jio 4G gives battery life better than other operators since it is only 4G it does not need to switch between 2G or 3G wasting battery.
