What’s the average battery life of an iPhone 13 Pro Max?

Apple says the battery lasts up to whopping 28 hours on iPhone 13 Pro Max during video playback, but it depends on your usage. For example, using your iPhone 13 Pro Max for audio playback and phone calls more than internet browsing will retain battery longer than usual.

iPhone 13 Pro Max has a 4352 mAh battery, better than all previous iPhone models so far. However, when you purchase a refurbished iPhone 13 Pro Max from Mobile Guru, the battery capacity is between 70%-100% depending on the device's condition.
