PhoneBuff has spent the past year developing the ultimate phone battery test. What makes this test peculiar is in its attention to detail. The test uses a temperature controlled environment and calibrates the screen brightness and speaker volumes of both phones being tested and contrasted to be identical. Also, the entire test is conducted with a robotic arm to make sure the exact same touches and manipulations are implemented on both phones at exact times which also ensures the same pattern of taps, app usage and even reaction times as it navigates through the phone. In short: this is as close to a perfectly controlled real-world battery life test as it is possible to achieve.
PhoneBuff, a popular YouTube site used the test on two of the latest flagship smartphones out right now, the Samsung Galaxy Note 9 and the iPhone XS Max. They discovered that considering the iPhone XS Max’s A12 Bionic processor which Apple sold to be the best and most efficient mobile processor in the world, and iOS 12 which Apple claims it’s the fastest and most efficient generation of iOS yet, the battery performance of the iPhone XS Max is pretty appalling.
Apple has been forced to admit its new iPhone XS (details) and iPhone XS Max (details). Though it had some major problems like the ChargeGate and BeautyGate which plagues this year’s new iPhone, Apple has been able to resolve them with software updates. Sadly, there seems to be nothing Apple can do to fix the newly discovered battery problem.
What PhoneBuff discovered is the iPhone XS Max which is the largest and most expensive iPhone ever made, having Apple’s largest phone Battery ever, couldn’t get close to the battery life longevity of its primary rival: Samsung’s Galaxy Note 9. In fact, when the iPhone XS Max died the Note 9 still had a massive 37% battery life remaining.
This is a shock for several reasons.
To begin with, though the Galaxy Note 9 has a larger battery, it’s only 20% larger (4,000 mAh vs 3,174 mAh). It would have made sense if the Note 9’s battery at the time the iPhone XS Max died was about 20 percent but it wasn’t (at 37 percent: that is too much of a gap)
Secondly, the Note 9 has a higher resolution display and driving pixels is the most demanding thing a phone does.
Deducing from this analysis, the only other variable that could influence the battery life of the iPhone XS Max is the software. This means Apple’s iOS 12 is not as efficient as they claimed.
Apple’s iPhone XS has a smaller battery than the Max which means it can’t even compete. The PhoneBuff’s test confirms without a doubt that the New iPhones ultimately comes up very short indeed and even a software update won’t go far to fix the issue. So if you plan to upgrade to a new iPhone this year, then the decision is easy because the iPhone XR is not only the cheapest and most interesting, it has much longer battery life too…
