Any device with low battery is deemed almost useless until you plug and see battery level rise. A full, green battery is always a sight to behold. But sadly, that is not always the case. Gadgets run on juice and most of them won’t last the whole day. The technique is to bring a charger or a power bank with you all the time. Or, just charge the device anytime there is a chance. You don’t want to suddenly run out of batt when you’re in an important conversation, do you?
