The new iPhone 17 and iPhone 17 Pro (Max) models have received some innovations including a 120Hz promotion screen for all models, vapor room for the Pro and 18MP Center Stage camera. But perhaps the most important new function is the extended battery life. The battery of the PRO models will last no less than four hours longer.
That is because Apple not only uses an more energy -efficient processor, the battery is also larger than in the previous models. This has given the battery life a big boost. We list the data for you.
Battery life iPhone 17 series
The battery life of the iPhone 17 and iPhone 17 Pro (MAX) has been considerably improved compared to earlier models thanks to larger batteries and an energy-efficient A19 chip. This allows you to play and stream videos for up to four to six hours longer, which ensures a much longer duration of use per load. Below we explain what has been adjusted.
Improved processor
The new iPhone 17 Pro (MAX) is equipped by Apple with the powerful A19 Pro processor that is considerably more energy efficient. This advanced 3-nanometer chip not only offers a faster 6-core CPU, improved 6-core GPU with neural accelerators, but also a powerful neural engine for machine learning and artificial intelligence.
The iPhone 17 is equipped with a reduced A19 chip with 6-core CPU and 5-core GPU. For both the standard model and the pro you will immediately notice these innovations in the longer battery life. Heavy tasks such as watching videos, gaming and photographing are performed smoothly and efficiently, while energy consumption remains low. Thanks to the chip, the battery will last for longer on a single charge.
The iPhone Air is equipped with the same A19 Pro chip but instead of 6-core GPU has this 5-core. This has a positive influence on the battery life, which is significantly less than the other new models.
Energy-efficient N1 chip
The new N1 chip in the iPhone 17 is a chip designed by Apple for wireless networks. This chip supports the latest standards such as WiFi 7, Bluetooth 6 and Thread, which means that faster, more stable and more energy efficient Wireless connections are possible. The N1 chip also improves the performance and reliability of functions such as the personal hotspot and airdrop.
Larger battery added
The iPhone 17, iPhone 17 Pro and iPhone 17 Pro Max are equipped with a larger battery. You can see this mainly in the increase in battery capacity (MAH). The iPhone 17 is ahead of the iPhone 16 no less than 8 hours, this is mainly due to the improved processor and N1 chip.
iPhone Air battery performance optimized
The iPhone Air has a smaller battery capacity, 3149 mAh, which is less than that of other iPhone 17 models. Apple accepts this concession due to the extremely thin and light titanium design of the Air. To keep the battery life acceptable, Apple uses advanced A19 Pro, N1 and C1X chips that are very energy efficient, together with software optimisations such as the new Adaptive Power Mode in iOS 26. There is also an optional magsafe battery that can extend the battery.
Battery capacity explained
The capacity of a battery is expressed in mAh which stands for Milliampère hour. This number expresses how long (in hours) the battery can give a certain current (MA) (HX MA). So if more power is required from the battery, the battery will be empty earlier.
For example, if you own an iPhone 17 Pro Max, it has a battery capacity of 5088 mAh. If you do not use it intensively, it uses an average of 110mA per hour and the battery lasts around 46 hours (5088/110 = 46.25 hours of battery life). Unfortunately, a device is used more intensively and you will soon be on a battery life of an average of 25 hours.
In the table you can see the battery life of different iPhone models. The figures are based on Apple’s official information and can vary in practice. Since the iPhone 11, Apple no longer gives an average battery life for data/internet and conversation duration, and since the iPhone 17 series also not for playing audio.
The battery capacity (MAH) of the new iPhone models is now officially announced by Apple on their specification page on the basis of the energy labels in the EU.

Battery capacity increased
What is immediately striking is that the battery capacity is increased for almost all models; The iPhone 17 Pro Max even has the longest battery life ever in an iPhone. The iPhone Air has a limited capacity and battery life and will feel limited for many users.
How long the battery of the iPhone 17 series will last for you is difficult to predict. This is purely dependent on the use; Not everyone uses his iPhone in the same way and uses the same networks: 3G/4G/5G. Under iOS 26 you can use adaptive power to automatically extend the battery life using small adjustments.
The battery duration figures give a result for similar use of audio, so that you can compare the battery capacity between the different models of iPhones. Combined use is simply not comparable and is different per user.
Always-on Display
The Always-on screen of the iPhone 17 (Pro) and iPhone Air ensures that you are always switched on the screen of the iPhone and the access screen is visible. By only renewing the screen with 1Hz, the battery is saved.
The Promotion OLED screen with dynamic refresh rate and the Display Engine in the processor ensure that the energy consumption of the Always-on access screen is kept to a minimum. In addition, the iPhone 17 series also has a minimum brightness of 1 nit. This means that the Always-on display can dim even further in a dark environment.
Fast loading drastically improved
Apple has improved wireless charging with Magsafe in the new iPhone models by increasing the maximum capacity. For example, with the help of Magsafe or Qi2 you can fast charging with 25 W wireless.
Do you charge the iPhone via a USB-C cable? Then you can be charged to 50% within 20 minutes with an adapter of 40 W or more on the iPhone 17 (Pro) models. The iPhone Air charges you to 50% within 30 minutes with an adapter of 20 W or more.
