The iPhone doesn't have the best track record for battery, whatever model you buy. However if you're determined to buy one but want to know just how well the battery can take a potential day's usage we've put together a vs test to see which will last you the longest.
For this test we combine different elements of a potential day's battery life in one test - browsing, gaming, youtube watching and running an internal 1080p video.
