The average smartphone run by the little green robot lasts for 5 hours and 38 minutes on a charge, but the average Android tablet stays juiced up for 6 hours 38 minutes. Neither of those runtimes equals a full work day, assuming you spend all day on the phone. You can add some time with a portable power pack, but those will cost you at least $20. Boost your battery life for free by following these 10 simple tips.
