iPhone batteries are generally quite powerful and last around 1 day if you’re calling, messaging, browsing or streaming throughout the day. The exact battery life of your iPhone depends on several factors, such as your iPhone model and the tasks you perform with it. Read all about iPhone battery life and how you can influence it yourself.
Phone battery life is often expressed in mAh. This stands for milliampere-hour and indicates how long a battery can run before it needs to be recharged. A battery with a capacity of 2,000 mAh can, for example, supply 1,000 milliamperes of power for 2 hours. In principle, the more mAh, the more powerful a smartphone battery is. We say ‘in principle’ because other factors also play a role in battery life, such as power-saving features and the power of the smartphone processor.
Although Apple never officially comments on the battery capacity of their iPhones, this has been researched by various parties. This is the capacity of the most recent iPhones:
The newest iPhone is the iPhone 17. In addition to the standard model, this series consists of the iPhone 17e, iPhone Air, iPhone 17 Pro and the Pro Max. The latter has the best battery capacity (4,823 mAh) and the best battery life of all iPhone 17 models. Suppose you were to play videos continuously: an iPhone 17 Pro Max would manage that for around 37 hours. In addition, you can charge these iPhones to 50% within 20 minutes with a charger of at least 40 watts.
Your iPhone’s battery life is influenced by various factors. The quality of a battery declines over time anyway. Other factors include the brightness of your screen, apps running in the background and constantly receiving updates, push notifications, poor Wi‑Fi or mobile signal strength, and excessive use of GPS. To extend battery life, you can reduce the brightness of the screen, regularly check which apps are active in the background and close the apps you are not using, and consider switching off push notifications for apps you don’t use very often.
