It can be frustrating to constantly have to reach for a charger throughout the day. That is why one of the most important factors that people consider when purchasing a new phone is the capacity of its battery. While iPhones generally have decent battery life, many people are curious to know if the latest iPhone 15 models offer any significant improvements in this area. If you’re trying to decide which to buy between the iPhone 15 Pro and the iPhone 15 Pro Max, it’s natural to want to know which one has a better battery capacity. In this article, we will take a closer look at the iPhone 15 Pro battery life and iPhone 15 Pro Max battery life to help you make informed choices and answer how long does the iPhone 15 Pro Max battery last. However, before we dive into that, let’s first consider the factors that determine a smartphone’s battery life.
Factors That Determine a Phone’s Battery Life
More often than not, battery life does not depend on how big it is. The capacity of a phone’s battery is a crucial factor that determines its ability to store power. In other words, the higher the milliampere-hour (mAh) rating, the greater the energy it can retain, resulting in a longer-lasting battery. That’s why we will also talk about iPhone 15 Pro Max battery life mAh as well as iPhone 15 Pro battery life mAh later in the article. Nevertheless, it is important to note that there are additional factors that influence the effectiveness of a smartphone’s battery, aside from its size. These factors encompass a range of considerations that contribute to the overall performance and longevity of the battery. The following factors determine a phone’s battery life:
1. Too Many or High-demanding Applications
Having numerous applications on your phone may seem appealing, however, it is important to note that a significant portion of these apps necessitate a substantial amount of energy in order to operate efficiently. Certain applications have the capability to run in the background, deplete your data, and place a significant strain on your battery life. Applications that rely on constant internet connectivity to perform their functions tend to drain battery life at a much faster rate compared to other applications that do not have such demanding requirements.
2. Phone’s Connectivity
Connectivities are undoubtedly an integral aspect of phones’ battery usage. This is because the more connections required, the more battery consumption. Among the most prominent connections are ones are Wi-Fi, Bluetooth, hotspots, data, and potentially even the location detector. The simultaneous activation of these connections has a substantial impact on draining the battery life of a phone. Apple has made efforts to enhance its hardware to mitigate the battery drain caused by these connectivities, but it merely lessens the overall effect. Hence, it is advisable to only enable these connectivities when necessary. Furthermore, it is crucial to note that network-dependent connectivities require more energy from the phone when the signal strength is weaker, as the device exerts additional effort to search for a stable connection.
3. Battery Usage
The way in which we utilize our smartphones varies among individuals. For instance, individuals who are avid gamers or movie enthusiasts are likely to experience a faster depletion of their phone’s battery compared to those who primarily use their phone for making calls and occasional internet browsing. It goes without saying that the level of activity conducted on our mobile devices directly correlates to the amount of power it consumes from the device’s battery.
4. Temperature Factor

Maintaining a moderate temperature in the surroundings of your smartphone is highly beneficial for its battery. Prolonged exposure to excessive heat or frequent usage in extremely hot weather conditions can have detrimental effects on the battery, leading to both decreased performance and potential damage. Also, prolonged exposure to extremely low temperatures can also impact battery life.
5. Screen Size & Resolution
Large-screen smartphones are not only convenient but also highly favored by a vast number of individuals. Nevertheless, the increased screen size comes with the drawback of consuming additional energy to illuminate the entire display. With a resolution of 1080, it is only logical to anticipate that the processor will require more power from the battery in order to effectively showcase these numerous pixels. While the depletion of battery life due to this factor might seem insignificant on an individual basis, it should be noted that over time, these small increments can accumulate and have a noticeable impact.
6. Age of Battery
It is important for all users to know that every battery has a limited lifespan, no matter how well it is used. As a battery ages, it tends to charge and discharge at a faster rate compared to when it was brand new. This is especially true for phone batteries, which experience constant usage and charging cycles. When your phone’s battery reaches this stage of deterioration, the most common solution is to replace it with a new one.
Now that we have discussed the various factors that affect the effectiveness of a smartphone’s battery, let’s delve into a detailed analysis of two popular Apple devices.
iPhone 15 Pro Battery Life
When it comes to the high-end models, the iPhone 15 Pro boasts a 3,274mAh battery capacity, which is fairly similar to its previous iteration. In terms of battery life, the iPhone 15 Pro impresses with 23 hours of video playback and 75 hours of audio playback. Surprisingly, despite having a slightly larger battery, Apple claims that the iPhone 15 Pro offers the same battery life as its predecessor, the iPhone 14 Pro. However, during a tomsguide testing, the iPhone 15 Pro actually had the shortest battery life among the devices that were examined. It managed to last for 10 hours and 53 minutes, which is 40 minutes longer than the iPhone 14 Pro. Nonetheless, the iPhone 15 Pro still outperformed the Google Pixel 7 Pro by approximately 3 hours.
iPhone 15 Pro Max Battery Life
The iPhone 15 Pro Max boasts an impressive 4,441 mAh battery, providing users with exceptional battery life. With a total endurance rating of 118 hours, this device is designed to last. According to Apple’s official specifications, the iPhone 15 Pro Max offers an impressive 29 hours of video playback and a whopping 95 hours of audio playback. In comparison, the iPhone 15 Pro offers 23 hours of video playback and 75 hours of audio playback. It is clear that the iPhone 15 Pro Max is the ultimate choice for those seeking long-lasting power. In our own testing, we observed a battery life of 14 hours and 2 minutes, which is slightly shorter than the iPhone 15 Plus but still surpasses the battery life of the iPhone 14 Pro Max by over 20 minutes.
iPhone 15 Pro Battery Life Hours Vs. iPhone 15 Pro Max Battery Life Hours
| Phone | Audio Playback | Video Playback | Video Streaming |
| iPhone 15 Pro | 75 hours of audio | 23 hours of video | Up to 20 hours |
| iPhone 15 Pro Max | 95 hours of audio | 29 hours of video | 29 hours of video Up to 25 hours |
The iPhone 15 Pro series this device can be conveniently charged using various methods such as MagSafe, Qi, and the USB-C cable. However, it is important to note that Apple no longer includes chargers in the packaging, meaning you will need to purchase these accessories separately. This naturally leads to the question of where to find the best chargers specifically designed for the iPhone 15 Pro and 15 Pro Max models. Fortunately, we have a wholesome list of Apple Certified Chargers that provides a solution that effectively eliminates any concerns or uncertainties you may have regarding charging your device. You can also purchase certified MagSafe Car chargers to keep your iPhone juiced up while on the go.
Conclusion
In terms of battery performance, the two iPhones being evaluated do not outrightly surpass their predecessors. In fact, there is a decrease in battery capacity and the amount of time one can use the device before needing to recharge. However, it is important to note that this slight reduction in battery capacity does not hinder the overall effectiveness of these smartphones. If your main concern is having a long-lasting battery, then I would highly recommend considering the iPhone 15 Plus or the iPhone 15 Pro Max. While they may come with a higher price tag compared to their smaller counterparts, the advantage of not constantly needing to charge your phone throughout the day is truly priceless for many individuals.
