Apple boasted in its presentation of the new iPhone 16 about the largest battery of these new models, especially the iPhone 16 Pro Max, but The good news is that tests indicate that with iOS 18 the battery lasts longer even on older phones, reaching an hour more in the case of the iPhone 15 Pro Max.
It’s one of the most important questions when launching a new model or a new update: how long does the battery last? In fact, it was one of the most highlighted features by Apple during the last presentation of the iPhone 16: the 16 Pro Max model can play videos for 4 hours more than the 15 Pro Max. This does not necessarily mean that your battery will last 4 hours more in real-world use, but it certainly does. They managed to improve the autonomy of the terminal. How did they achieve this? Well, probably by using a bigger battery, a more efficient processor, and software that is better optimized for power consumption. The latter seems to be very important this year, as the improvement in battery life is not just for the latest iPhone 16, there are tests that indicate that older models are also increasing their battery life, with the iPhone 15 Pro Max being the main beneficiary, reaching to squeeze the battery up to an extra hour of autonomy.
The tests were done by Geekerwan on his YouTube channel (link) by performing some tests in which he used voice and video calls, WeChat messaging, web browsing, TikTok and games like Genshin Impact. These tests carried out on the iPhone 15 Pro with iOS 17, the phone reached an autonomy of 6 hours and 22 minutes, while with iOS 18 it reached 6 hours and 55 minutes, about 33 minutes more. However, its older brother, the iPhone 15 Pro Max, with a larger battery, reached with iOS 18 up to 9 hours and 2 minutes, while with iOS 17 it remained at 7 hours and 56 minutes, reaching more than an hour of autonomy. with the latest Apple update. Do you notice it in your real use of the terminal?
