iPhone 5 vs Galaxy S3: S3 Makes Promises It Can’t Deliver [Results Of Battery Test]

By  | 

The iPhone 5 and the Samsung Galaxy S3 are without doubt THE phones of 2012, and there has been countless comparisons written about them – we’re going to look at just real-world battery life here.

iPhone 5 vs Samsung Galaxy S3: battery life

A big concern for many about the iPhone 5 is battery life – previous iPhones haven’t had massive batteries, and none have been removable. The iPhone 5 has a 1,440mAh battery (non-removable) and the Samsung Galaxy S3 has a removable 2,100mAh battery.

Apple claimed that this latest battery would be the best of the bunch, and it seems that it is. Tests on the two batteries included Wi-Fi web browsing performance, and they showed that the iPhone 5 lasted for seven hours and 13 minutes on Verizon. By comparison the older iPhone 4S lasted for just under six hours. Now the Samsung Galaxy S3 lasted for just under seven hours on Verizon, so the iPhone 5 lasted for (slightly) longer than the Samsung Galaxy S3 and the 4S. The top device, however, was the Droid Razr Maxx, with eight hours and 25 minutes as we’ve seen in previous test.

This is very much at odds with the Samsung Galaxy S3 specs sheet, which promises around 12 hours that’s well over that of the iPhone 5. So it looks like the smartphones are level-pegging despite the different battery capacities.
