The iPhone 14 Pro Max has the longest battery life of any iPhone, according to a recent study by PhoneArena. The study found that the iPhone 14 Pro Max can last up to 28 hours on a single charge, while the iPhone 14 Pro can last up to 22 hours and the iPhone 14 can last up to 19 hours.
The iPhone 14 Pro Max's long battery life is due to its larger battery size, as well as its more efficient A16 Bionic chip. The iPhone 14 Pro Max has a 3,095 mAh battery, while the iPhone 14 Pro has a 2,775 mAh battery and the iPhone 14 has a 2,227 mAh battery.
The iPhone 14 Pro Max also has a more efficient A16 Bionic chip than the other two models. The A16 Bionic chip is made using a 5-nanometer process, which is smaller than the 6-nanometer process used in the A15 Bionic chip. This allows the A16 Bionic chip to use less power while still providing the same level of performance.
If you're looking for an iPhone with the longest battery life, the iPhone 14 Pro Max is the best option. However, if you're on a budget or don't need as much battery life, the iPhone 14 or iPhone 14 Pro are still great choices.
Here is a table of the battery life of all the iPhone 14 models:
| Model | Battery Life |
|---|---|
| iPhone 14 Pro Max | Up to 28 hours |
| iPhone 14 Pro | Up to 22 hours |
| iPhone 14 | Up to 19 hours |
