Apple’s iPhone X Beats iPhone XS Series In Battery Life Test

The iPhone XS and XS Max are supposed to be better than last year’s iPhone X in all aspects. However, a recent battery life test showed that the current-generation iPhones are unable to last as long as the 10th anniversary model on a single charge.

Tom’s Guide disclosed Monday the results of the battery test it conducted on the iPhone XS and the XS Max. According to the product reviews site, the bigger iPhone XS Max lasted nearly an hour longer than the iPhone XS during the test. However, the 6.5-inch OLED model did not surpass the record of last year’s 5.8-inch OLED model.

The battery test conducted involved continuous web surfing at 150 nits of screen brightness. Throughout the duration of the test, Auto-Brightness and True Tone were switched off in the display settings of the devices. The iPhone XS and the iPhone XS Max were running on T-Mobile’s network and to ensure that they maintain full signal strength, a signal booster was used.

The iPhone XS Max was able to last for 10 hours and 38 minutes. On the other hand, the iPhone XS last for 9 hours and 41 minutes. When Apple introduced the two new flagship handsets, the Cupertino giant claimed that the iPhone XS is capable of lasting 30 minutes longer than the iPhone X. But clearly, that’s not the case here. The iPhone X recorded 10 hours and 49 minutes when Tom’s Guide subjected it to the same test.

The iPhone XS Max has better battery life than the iPhone XS and it even surpassed the smartphone category average of 9 hours and 48 minutes. Despite the impressive performance of the iPhone XS Max, it still wasn’t able to outperform the iPhone X.

It’s important to note that a teardown recently found that the iPhone XS sports a 2,659 mAh battery, which is smaller than the 2,716 mAh battery inside the iPhone X, according to AppleInsider. Meanwhile, the iPhone XS Max houses a 3,179 mAh dual-cell module.

Another thing to point out is that battery size is just one facet of battery life. The processor, software and other aspects of smartphones also contribute to battery life. The A12 Bionic processor that’s powering the new iPhones is supposed to be 50 percent more efficient than the A11 Bionic inside the iPhone X. Nevertheless, the new models still failed to match or surpass the longevity of the older flagship device.
