iPhone 15 Pro’s Performance and Battery Life Apparently Improved After iOS 17.0.3 Update

After the A17 Pro was initially put to the test, the results were not particularly intriguing, with problems of overheating surfacing online. Not only that, but the chipset failed to reach its maximum potential due to excessive thermal throttling, to the point where it struggled to keep up in even the most basic of testing scenarios.

Apple addressed the issue in the new iOS 17.0.3 update, which apparently seemed to fix the issue, somewhat. However, the more important speculation was: did Apple push back the performance numbers on the 15 Pros to stop them from overheating. Well, as it turns out, no.

Recently, after the 17.0.3 update was shipped out, YouTuber ITSub tested the performance and battery life of the iPhone 15 Pro against the iPhone 14 Pro, both running the same version of iOS.

Not only did Apple fix the issues with excessive heat generation, but it managed to bump up the performance too. To compare the graphical performance of the iPhone 15 Pro, it was put to test under the 3DMark Wild Life Extreme Stress Test, where it managed to obtain a quite decent score of 4274. This is ~13% improvement over the 3757 on iOS 17.0.2.

The iPhone 14 Pro also seemed to have gained some sort of an improvement, gaining a small 8% advantage over the previous best score. All in all, the iPhone 15 Pro was ~27% better than the last year’s iPhone 14 Pro.

As for battery life, the update did bring about some degree of improvement, but not enough to make a significant difference compared to the iPhone 14 Pro. However, the iPhone 15 Pro did see about 3-4% more than that on iOS 17.0.2.

From a broader perspective, iOS 17.0.3 did seem to have addressed most of the problems that people had with their phones, but at the same time, also has ignored some, such as the Wi-Fi disconnection issues. Not to mention how, the battery life is still not better than last year’s iPhone 14 Pro, despite having a supposedly “more-efficient” 3nm SoC.
