The Samsung Galaxy S4 was named as the smartphone with the best battery life in a test conducted by Which?, a UK-based phone review website.
The 2013 Samsung Android flagship beat other flagship handsets, both in the Call Time or Number of Minutes category and Internet Use category.
In the first category, the Galaxy S4 was recorded to have 1051 minutes of call time. It was followed by the Sony Xperia Z, with 985 minutes; then by the Google Nexus 4, with 846 minutes; the HTC One, with 771 minutes; the Blackberry Z10, with 600 minutes, and lastly, the Apple iPhone 5 16GB, with 499 minutes.
In the second category, the same handset was clocked to have 405 minutes. It was succeeded by the HTC One, with 339 minutes; the Blackberry Z10, with 335 minutes; the Sony Xperia Z, with 322 minutes; the Google Nexus 4, with 308 minutes; and the Apple iPhone 5 16GB in the last place again with 261 minutes.
In terms of charging time, however, the Apple iPhone 5 16GB scored higher than any of the smartphones included in the test. The iPhone 5 had a charging time of only 141 minutes. Next is the Nokia Lumia 920, with 152 minutes; the Samsung Galaxy S4, with 164 minutes; the Blackberry Z10, with 170 minutes; the Sony Xperia Z, with 171 minutes; and the Google Nexus 4, with 211 minutes.
According to Which?, the Samsung Galaxy S4 bested the other handsets because of its 2,600mAh battery, which is able to offer at least two times the battery life of the iPhone 5. By comparison, the iPhone 5 has a battery with a lower capacity of 1440mAh. This does not allow it to store as much battery juice as the others that were tested. Nonetheless, Apple is reportedly developing a successor to the iPhone 5 which would have a better battery life.
Which? reached these results by using a phone network simulator to ensure that the signal strength does not vary duing the test. It also ensured that the brightness level on the handsets were the same. To allow each handset to perform at its optimum, it also charged the phones fully. Which? clarifies, however, that the test is only a representation. It was performed to give consumers a better idea of how each handset fares when put to the test. Actual usage of the handsets may indicate varied levels of battery life, depending on how the consumer uses the smartphone.
