iPhone 13 Pro Max Battery Test
Testing the endurance of the iPhone 13 Pro Max battery, we fully charged the device and conducted several battery checks as follows:
- Battery test through continuous single-task usage
In the first battery check for the iPhone 13 Pro Max, we experienced five basic tasks, namely Facebook, Safari, Youtube, Messenger, and Tiktok.
We dedicated one hour to each task. As each hour passed in one app, we switched to the next app, sequentially. After experiencing all five tasks, totaling 5 hours, the iPhone 13 Pro Max battery dropped by 40%, with Messenger and its video call experience consuming the most battery.
- Battery test through continuous multitasking
Next is the battery test of the iPhone 13 Pro Max by continuously rotating among four common tasks: Facebook, Safari, Youtube, and Mobile Legends. After one hour in each app, we switched to another app, maintaining consistent conditions, including screen brightness and phone settings such as GPS, Bluetooth, throughout the battery test. At the start of the test, the iPhone 13 Pro Max was fully charged at 100%.

After continuous usage, the iPhone 13 Pro Max powered on for an impressive 12 hours and 17 minutes before shutting down. Quite a remarkable figure, isn't it? Despite having a battery of over 4000mAh, the device's performance exceeds expectations, thanks to the well-optimized Apple A15 Bionic chip.
- Battery test through 3D gaming
Playing graphics-intensive games typically drains the battery quickly, and users often wonder how long the iPhone 13 Pro Max would last during gaming sessions. To further verify the battery life of the iPhone 13 Pro Max, we conducted a gaming test with familiar titles including PUBG Mobile, Call of Duty Mobile, Mobile Legends, League of Legends: Wild Rift, and Genshin Impact.
For each title, we participated for approximately one hour, totaling five hours of gaming. After this duration, the iPhone 13 Pro Max battery depleted by 62%, with Genshin Impact consuming the most energy at 16%.
Charging speed of iPhone 13 Pro Max
The iPhone 13 Pro Max is supported with 20W charging. To date, the charging speed of iPhones still outpaces other Android smartphones. Specifically, it takes nearly 2 hours for the iPhone 13 Pro Max to reach a full charge.

It might sound like a while, but if you're about to head out and your battery is running low, a quick 30-minute charge will give you a comfortable 48% for half a day of usage.
