The iPhone 5 and the Samsung Galaxy S4 and S3 devices have been going head to head in the market for awhile now. One key difference is between the iPhone 5 and Samsung Galaxy battery life. Tech Cocktail recently did a breakdown between the iPhone and the Galaxy S4 battery life.
The Galaxy S4 has a very large battery at 2600 mAh. Even with the huge screen and top-of-the-line hardware, the charge lasts an incredible amount of time. At full charge it gives users 1,051 minutes of call time or 405 minutes of browsing the Web, while taking just 164 minutes to fully charge if drained.
The iPhone 5 has just a 1400 mAh battery, which is a lot smaller than than the S4. While offering the shortest charge time at just 141 minutes amongst smartphones, it doesn't hold its charge well, offering just 499 minutes on calls or 261 minutes on the Web.
Meanwhile, the S3 was tested by Tekrieg, which found that although Samsung stated that it provided 15 hours of battery life, it tested substantially less than that. The S3 also has a larger battery than the iPhone 5 at 2100 mAh, which is slightly smaller than the S4 model. However, the battery only lasted around 7 hours, which is comparable to the iPhone 5.
These tests were conducted only doing basic smartphone tasks such as talking on the phone or surfing the Web. The tests don't account for games or other applications that can eat up battery life at different rates. In reality, the amount of battery charge that people use up depends entirely on what they use the device for and the applications it is running.
Replacing iPhone battery or a Samsung battery can greatly improve charge. Users can send their phones into iResQ to have the battery replaced for either type of device.
