iPhone 13 Battery Life

There’s been significant chatter about the iPhone 13’s battery life. Is it better than previous versions? When it was first pitched by Apple they claimed the 13 Pro would last 1.5 hours longer than the iPhone 12 Pro. Did the iPhone 14 and now the 15 about to be released improve on the battery technology? What does the real-world use look like? Now that we have several years of data let’s look at the iPhone 13 battery life details and what ended up being true and what didn’t pan out.

Notable Battery Features of the iPhone 13

A15 Bionic Chip

At the heart of the iPhone 13 lies the A15 Bionic chip, the brainchild of Apple’s engineering marvel. It’s not just about performance; this chip is designed for power efficiency. Think of it as a car engine that gives more mileage with less fuel.

Power Efficiency

With improvements in software optimization and hardware integration, the iPhone 13 boasts remarkable power efficiency. This means the phone drains the battery at a slower rate, akin to a dripping tap versus a flowing one.

Larger Battery Capacity

Apple upped the ante by including a larger battery in the iPhone 13, making it a resilient warrior against daily tasks and then some. It’s like having an extra snack in your backpack for those unexpected hunger pangs. If you look at a side by side of the iPhone 13 vs an iPhone 12 battery you’ll notice the size and shape is totally different. The battery on the 13 is now L-Shaped and this additional space allows them to deliver more charge capacity. As an example, the iPhone 13 Pro has an 11.97 Wh capacity which is an 11% improvement over the iPhone 12 Pro (which had a 10.78 Wh capacity).

Real-World Battery Life Experiences

Regular Use

For the average user, who browses the internet, checks emails, streams videos, and occasionally plays games, the iPhone 13 stands tall. Many users report comfortably getting through a day and a half without reaching for the charger.

Heavy Use

Gamers, video editors, and those constantly on video calls might drain the battery faster. Yet, even for this cohort, the iPhone 13 often stretches throughout the day without gasping for a charge.

Tips to Extend iPhone 13 Battery Life

Screen Brightness

A simple yet effective trick. Adjusting screen brightness or enabling auto-brightness can be likened to turning off lights in an unused room – it saves energy.

Location Services

Do all your apps need to know where you are? Probably not. Turning off unnecessary location services is like closing the windows on a cold day – it conserves warmth.

Background App Refresh

Some apps constantly update in the background. Consider it like someone constantly opening your fridge – energy gets wasted. Turning this feature off for non-essential apps can conserve battery.

Charging the iPhone 13

Fast Charging

Need a quick juice-up? The iPhone 13 supports fast charging, which feels almost like a turbo boost, getting you from 0% to 50% in just about 30 minutes.

Wireless Charging

Gone are the days of fumbling with wires. With the iPhone 13, place it on a Qi or Qi2-compatible charger, and it sips power effortlessly, like drinking with a straw.

Wireless charging is a great feature if your case allows it. Make sure that the case you choose is thin enough to let the charger interact with your phone – otherwise you’ll have to remove your case every time you want to charge your phone.


The iPhone 13’s battery life isn’t just a minor improvement; it’s a testament to Apple’s commitment to user experience. With the right features, optimizations, and user habits, this device promises to be a reliable companion from dawn to dusk. And as with any gadget, treat it well, and it’ll reciprocate with stellar performance.
