Battery life, Generation 17: What the new iPhones can do
Apple has published details on the batteries of the iPhone 17, iPhone Air, iPhone 17 Pro and iPhone 17 Pro Max. There are one or two surprises.
iPhone 17: Apple's new entry-level model.

A first cell phone with a battery of over 5000 mAh, a model with almost 20 percent more battery capacity: Apple has upped the ante when it comes to the power supply of its new iPhone models. It is commendable that the company has now provided specific information on how much mAh is in each model. Apple also has to provide this information due to the new EU energy labels.
More juice for the iPhone
However, the published information only applies to models that have a SIM card slot. Apple currently still installs this in the EU. In regions such as the USA or Japan, there are only devices with eSIM. The manufacturer uses the space gained for slightly larger batteries, which, according to the manufacturer, enable around two hours more video playback.

According to the published data, the iPhone 17 has 3692 mAh (volt count unchanged), which would be an increase of just under 3.8 percent compared to the iPhone 16. The iPhone Air, which replaces the iPhone 16 Plus in the portfolio, is equipped with 3149 mAh (eSIM-only worldwide). The Pro models are even more powerful. Apple has given the iPhone 17 Pro over 18 percent more battery (4252 mAh) than the 16 Pro, while the iPhone 17 Pro Max now has 5088 mAh. The latter would be the first time that Apple has installed a battery with over 5000 mAh. The increase in capacity compared to the 16 Pro Max is slightly less than 9 percent.
Change in material and heat dissipation
Apple has made numerous hardware changes to the new Pro models. For example, the housing is now an aluminum unibody, as we know it from the MacBook. The glass surface on the back has been replaced by a smaller “Ceramic Shield,” where the MagSafe charging pad is also located. Inside, there is also vapor-chamber cooling for the first time, which relies on sealed liquid and is intended to ensure that heat is dissipated more quickly.
Apple built the last two Pro model generations with a titanium frame, which initially led to complaints about the hardware running too hot. This was logical: titanium has poorer thermal conductivity than aluminum, which was previously only used in the standard models. Surprisingly, Apple is now even advertising this: at the keynote, it said that the thermal conductivity of the new Pros is now “20 times greater.” Buyers of previous models with titanium frames will not like this at all.
