According to a battery test conducted by Tom's Guide, the new iPhone 14 Pro Max lasts two hours longer than the previous one.

Tom's Guide stated that the iPhone 14 Pro Max lasted an average of 14 hours and 42 minutes on a single full charge. The iPhone 13 Pro Max took 12 hours and 16 minutes to complete. On Tom's Guide's ranking of battery life in phones, the iPhone 14 Pro Max is in second place after the Asus ROG Phone 6 Pro, which has a battery life of around 15 hours.

Tom's Guide found that the iPhone 14 Pro Max only drained 30% of its power in 5 hours.

Anecdotally, the iPhone 14 Pro Max fared quite well in terms of endurance. After charging close to 90% and then using the phone from 1 p.m. to 6 p.m. for downloading apps, playing music and shooting photos and videos, the phone's battery only dropped to 60%.

Tom's Guide's test results don't match Apple's claim that the iPhone 14 Pro Max can charge up to 50% in 30 minutes. It only charged 42% from nil in half an hour.

Unfortunately, the iPhone 14 Pro Max sticks with 20W charging, so there are faster charging phones out there. Charging a drained iPhone 14 Pro Max, we got to only 42% in 30 minutes; Apple claims you can hit 50%, so we'll be retesting and updating this review. By comparison, the Galaxy S22 Ultra got to 58% in 30 minutes with its 25W charger, and the OnePlus 10 Pro reached 93% and got to 55% in 15 minutes, benefitting from 65W charging speeds.

The new A16 Bionic chip and a more efficient display are some of the benefits of the new iPhone 14 Pro Max. The iPhone 14 Pro has a more advanced display with a variable refresh rate, as opposed to the last year's model which had a low refresh rate.

On top of the more efficient panel, the display is now controlled by a new display engine embedded in the A16 chip that mitigates power consumption and features like Dynamic Island and ProMotion.

A more detailed look at Dynamic Island, the new 48MP Main camera, the always-on display, and more can be found in the reviews of the Apple products. The new phones will be arriving on September 16.
