iPhone 17 Pro Max Performs Predictably in Recent Wi-Fi and 5G Battery Drain Test Results

Battery performance assessments on smartphones often fail to reveal the complete scenario due to their predominant reliance on Wi-Fi connectivity during tests. However, a recent analysis diverges from this norm. It evaluates the iPhone 17 Pro Max under both 5G and home Wi-Fi conditions, offering insights into real-world usage scenarios. Even without delving into the full details of the test, one might anticipate a clear frontrunner, yet further examination reveals intriguing aspects worth discussing.

New Battery Drain Test Reveals iPhone 17 Pro Max Retains 25% Charge, While Competitor Shuts Down

The YouTube channel PhoneBuff recently received requests to incorporate 5G battery drain tests into their evaluations. Complying with this demand, they faced challenges due to the multitude of factors influencing battery life. As a result, the runtime displayed in the subsequent video may not accurately reflect the typical user’s experience, as personal habits play a significant role in device usage.

In general, a smartphone exclusively connected to Wi-Fi tends to outperform its 5G-enabled counterpart, primarily because the distance to a home router is generally less than 25 meters. Consequently, the wireless chip in the iPhone 17 Pro Max doesn’t exert much effort. In contrast, when utilizing 5G connectivity, the modem undergoes considerable strain, as users are seldom positioned near a cellular tower. Thus, the device must continuously seek the best signal and manage connections across various towers.

Furthermore, while connected to a 5G network, the iPhone 17 Pro Max may engage multiple radio connections simultaneously, contributing to increased battery consumption. These factors lead to the conclusion that Wi-Fi-connected smartphones usually provide longer usage times, but by what margin? To answer this question, two iPhone 17 Pro Max devices, both calibrated identically, were placed head-to-head in the test.

Initially, both models exhibited equal battery levels. However, upon opening FaceTime, a stark contrast emerged: the 5G iPhone 17 Pro Max experienced a 42% decline in battery life, whereas the Wi-Fi-connected unit only dropped by 25%.Under routine activities like scrolling and standby, both devices showed minimal battery drain, but launching FaceTime significantly impacted the 5G model.

iPhone 17 Pro Max (Wi-Fi only) – 25% battery remaining after 26 hours and 22 minutes
iPhone 17 Pro Max (5G only) – 26 hours and 22 minutes

What Factors Were Not Considered in the Battery Drain Test?

While this recent comparison highlights the significant drawbacks of exclusively using 5G, the content creator also identified aspects that were not addressed in the tests. Their acknowledgment of these limitations is commendable, as it reinforces the understanding that device performance can vary greatly based on user context.

The iPhone 17 Pro Max was tested in a stationary setting, which does not reflect real-world conditions where the modem would need to switch between cellular towers, potentially draining battery life more rapidly.
The test was conducted in a single location; varying locations would undoubtedly yield different outcomes based on signal strength and network quality.

It’s essential to emphasize that we are not underestimating the iPhone 17 Pro Max’s battery efficiency. Notably, it is remarkable that the Xiaomi 17 Pro Max, equipped with a robust 7, 500mAh silicon-carbon battery, only slightly surpassed Apple’s flagship by a mere five minutes. Anticipation builds for the iPhone 18 Pro Max, which is rumored to feature the largest battery in any non-foldable smartphone, hinting at even greater run times to come.
