Iphone 12 Pro Max Battery Life Test: Not Open 5g Can Still Be

[The iPhone 12 Pro Max has a number of improvements over the iPhone 11 Pro Max, but not battery and battery life. The iPhone 12 Pro Max is 0.7mm thinner than the iPhone 11 Pro Max, compared to the two generations of the “Big Cup.” The iPhone 12 Pro Max battery is 3687mAh, a 7 percent decrease from the iPhone 11 Pro Max’s 3969mAh battery.

Of course, there appears to be no necessary link between battery capacity and battery life for the iPhone, which is “not about battery size, but about optimization.” The battery life data of the iPhone 12 Pro Max and iPhone 11 Pro Max are identical in the product information marked on Apple’s website. What about the actual experience? Take “King of Honor” for example, playing for 1 hour under the same settings – connected to Wi-Fi, screen brightness 50%, sound 50%, and high frame rate mode on – the iPhone 11 Pro Max The power consumption of iPhone 11 Pro Max is 18%, while the power consumption of iPhone 12 Pro Max is only 13%. So look at the A14 bionic based on the 5nm process, it’s really something! In the face of diminishing battery capacity, can the new machine’s battery life still satisfy users?

This month’s Dr. Geek Classroom, we will test the battery life of the iPhone 12 Pro Max in Wi-Fi, 4G, and 5G networks, and see how it performs. The iPhone 12 Pro Max was connected to Wi-Fi, set to the highest screen brightness and 50 percent volume, and conducted seven tests of “WeChat voice call, WeChat video call, Weibo, Jitterbug, reading e-books online, playing “Honor of Kings,” and playing online 1080P video,” each test time

Switch to a 4G network and repeat the test with the following results: Except for two tests of WeChat voice calls and ShakeYin, the power consumption of the iPhone 12 Pro Max has increased when compared to connecting to Wi-Fi. With a 19% and 18% ratio, the top application scenarios for power consumption are still WeChat video calling and playing “King of Honor,” respectively. The iPhone 12 Pro Max has the longest battery life in the series (the iPhone 12 mini is now bowing its head in shame), so if that’s why you decide to buy this “mega-cup” instead of the other “large, medium, or mini-cups,” you won’t be disappointed with its battery life, at least when connected to Wi-

After almost a month with the iPhone 12 Pro Max, the average daily screen usage time is 7 hours and 16 minutes (source iPhone’s screen usage time). If you leave with a full charge at 8 a.m. and don’t charge it throughout the day, you should have 20 percent to 30 percent of the battery remaining when you get home at 7 p.m. The iPhone 12 Pro Max is still set to the highest screen brightness and 50% volume, in the case of 5G connection “WeChat voice calls, WeChat video calls, brush microblogging, Jitterbug, online reading e-books, play “glory of kings”, play online 1080P video” seven tests Each test time is still 1 hour The results of the tests are compared to those of Wi-Fi and 4G connections, as shown in the chart below.

In the seven tests, turning on 5G increased the power consumption of the iPhone 12 Pro Max by 80 percent, 22 percent, 29 percent, 17 percent, 33 percent, 71 percent, and 67 percent, with an average increase of 46 percent. The power consumption in the seven tests increased by 80 percent, 17 percent, 29 percent, 40 percent, 14 percent, 33 percent, and 43 percent, with an average increase of 37 percent, compared to 4G connection. Although there may be errors in different application scenarios, it is clear that after turning on 5G, the battery life of the iPhone 12 Pro Max will shrink significantly. Apple has also taken this situation into consideration, and when it released the iPhone 12 series, it stated that it would benefit from 5G by optimizing the iOS framework so that all types of apps can benefit from 5G without using more power, and introduced a new feature called “Smart Data Mode.” Apple stated, “(With Smart Data Mode), iPhone will automatically use LTE to save battery usage when immediate 5G speeds become essential, and start using it when immediate 5G speeds become essential.”

In practice, smart data mode, also known as “auto 5G,” can reduce power consumption to a degree, but the effect is limited. So, if you want to get a longer battery life, it is best to use 4G mode exclusively for daily use. It is also recommended that you manually activate 5G when performing 5G high-speed scenarios such as watching 4K videos, downloading programs or caching audio and video, and synchronizing data in the cloud. This method may be more secure than “auto 5G,” but it should be noted that the iPhone lacks a separate “5G switch” in the control center, as do Android phones, and changing the cellular network connection still necessitates going to “Settings – Cellular Network – Select Cellular Number – Voice and Data” to make changes.

Overall, despite the slightly shrunken battery, the iPhone 12 Pro Max delivers an excellent battery life thanks to the higher energy efficiency supported by the new A14 Bionic chip and Apple’s excellent “skills.” However, the new 5G becomes a barrier to the iPhone 12 series’ ability to provide long-lasting battery life.

At this point, consumers may not use 5G frequently, but as 5G coverage expands, future 5G application scenarios and hours of use will undoubtedly increase, and by then, the iPhone 12 series, which has become “old,” may face a more serious battery life challenge. Next, Apple’s optimization of the iPhone 12 battery life and whether the new iPhone will be equipped with a larger battery are worth monitoring.
