In this comprehensive article, we will conduct a thorough battery drain test to compare the battery performance of the iPhone 15, iPhone 14, and iPhone 13. All three devices are brand new and have their display brightness set evenly.
To ensure fair testing conditions, all iPhones are connected to the same Wi-Fi and cellular networks running the latest iOS version 17. It’s important to note that the results presented here may not reflect individual usage patterns, as variables like standby time, cell signal strength, temperature, and personal device usage can impact battery performance differently for each user.
Web Browsing Test
For the first test, we will browse the web using Safari on all three devices for one hour. After this hour, we observed that the iPhone 15 demonstrated a slight lead in battery efficiency compared to the other models. However, it’s essential to interpret battery test results with caution, as uncontrollable variables can always influence the outcome.
The iPhone 15 houses a 3349 milliamp-hour battery, a slight upgrade from the 3279 milliamp-hour battery found in the iPhone 14. Surprisingly, the iPhone 13 performed marginally better than the iPhone 14 in this test, although such variations should be treated with scepticism due to the inherent unpredictability of testing conditions.
Moving on to the gaming test, we played Minecraft on all three devices, ensuring that graphics settings were consistent to maintain fairness. The devices experienced similar battery drain percentages, with variations ranging between one and three percentage points. It is worth noting that all three devices performed admirably during this gaming session.
Video Streaming Test
Next, we return to YouTube for an hour of video streaming, then check the battery levels after this second hour of media consumption. Surprisingly, both the iPhone 13 and iPhone 15 exhibited a seven percent battery loss, while the iPhone 14 experienced a slightly higher drain of nine percent. These results imply that the iPhone 13 and iPhone 15 perform similarly in terms of energy efficiency during video streaming, with the iPhone 14 trailing slightly behind.
Overall Performance and Recommendation
The iPhone 15 can be considered an incremental upgrade over its predecessors. It introduces features such as the dynamic Island on the standard, USB-C compatibility, and a slightly modified design, giving the device a more premium feel. However, if you currently own an iPhone 13, upgrading to the iPhone 15 may not be necessary or recommended.
As the test progressed, we conducted post-web browsing and Instagram scrolling check-ins. Remarkably, after 9 hours and 52 minutes, the iPhone 14 ran out of battery. It is important to note that this result should not be considered significant, as battery performance can vary in individual devices due to pre-existing conditions or other factors. IPhone 13 and iPhone 15 experienced similar battery drain percentages during the extended test, but the iPhone 13 outlasted the iPhone 15 before finally running out of battery.
All three of Apple’s latest standard iPhones showcased fantastic battery life throughout this battery drain test. The iPhone 15 demonstrated slightly improved battery efficiency compared to its predecessors. Nevertheless, it is crucial to remember that these tests cannot account for all real-world variables that can impact battery performance. Personal usage patterns, network conditions, and numerous other factors may influence your iPhone’s battery life differently.
