iPhone 13 series battery life revealed

Apple’s 2021 iPhone 13 series retains the familiar looks of the iPhone 12 family, but offers some very significant upgrades inside, so there’s plenty to be excited about.

Faster performance, improved cameras (especially on the Pro models), more storage on the base models, there’s a lot to unpack.
But what we focus on here is improved battery life. The biggest beneficiary of this change is the iPhone 13 Pro Max, which now qualifies for the title of most durable iPhone ever. Not bad is not it ? And all the other models, even the mini, get welcome battery life upgrades.

Update: Official records of the exact iPhone 13 battery sizes have surfaced, and you can find them below.

We’ve tested all four iPhone 13 models using our three independent battery tests (conducted under identical, light-controlled conditions), and below you can see the results for each new iPhone.

iPhone 13 Battery Test Results

Disclaimer: iPhone 13 Pro and Pro Max tested with ProMotion active (variable display refresh rate 10-120Hz).

As you can see, all four iPhones score various battery life improvements over their predecessors.

Below, you’ll also find official iPhone battery life figures from Apple itself:

iPhone 13 series battery improvements:
  • iPhone 13 mini lasts 1.5 hours longer than iPhone 12 mini
  • iPhone 13 lasts 2.5 hours longer than iPhone 12
  • iPhone 13 Pro lasts 1.5 hours longer than iPhone 12 Pro
  • iPhone 13 Pro Max delivers 2.5 hours longer than iPhone 12 Pro Max

Yes, that means the iPhone 13 Pro Max has the longest battery life ever seen in an iPhone.

Apple also provides the following estimates for battery life when streaming video:

  • iPhone 13 Pro Max — 25 hours
  • iPhone 13 Pro — 20 hours
  • iPhone 13 — 3 p.m.
  • iPhone 13 Mini — 1 p.m.
  • iPhone 12 Pro Max — 12 hours
  • iPhone 12 Pro — 11 hours
  • iPhone 12 — 11 hours
  • iPhone 12 Mini — 10 hours

It’s super impressive. We could not confirm all of these numbers. For example, Apple claims that the iPhone 13 Pro Max has DOUBLE the battery life of its predecessor in some respects, and we don’t see such a big increase in real life.

Apple also provides a few other metrics for battery life, like music playback and offline video playback, and the differences aren’t quite as dramatic, but there are obviously plenty of improvements.

Teardowns revealed battery capacity on iPhone 13/mini/Pro and Pro Max

Apple doesn’t officially provide battery capacity numbers on its website, but device teardowns reveal exact numbers for each model.

Interestingly, the iPhone 13 turns out to have a bigger battery than the Pro model. Also, if you’re wondering which model has the biggest battery boost, it would be the iPhone 13 Pro Max. The iPhone 13 mini also gets an almost 10% battery boost over the 12 mini.

Here is the exact battery capacity on each iPhone 13 model:

Obviously, the sheer size of each phone contributes to different battery upgrade possibilities, but those are pretty solid numbers across the board.

Does that mean we don’t have to worry about the iPhone 13 battery draining?

All iPhone 13 models have improved battery life. We haven’t seen any reports of battery drain issues.

Apple officially says these iPhones have “all-day battery life”, a pretty vague statement indeed.

Does the iPhone 13 have reverse wireless charging?

The iPhone 13 does NOT officially offer a feature called reverse wireless charging.

This feature is common on Android flagships where the phone can act as a battery and charge other gadgets like a smartwatch or wireless headphones. The iPhone 13 series cannot do this.

Does the iPhone 13 have MagSafe?

All iPhone 13 models come with MagSafe wireless charging. Thanks to the magnets placed in a circle on the back of the iPhone, each of the phones can firmly snap onto compatible chargers and maximize wireless charging efficiency.

The actual power and shape of the magnets remained the same as on the iPhone 12 series, as did MagSafe’s 15W maximum charging speed. Keep in mind that to get this maximum speed you need to have a compatible device. MagSafe charger.

What charger does the iPhone 13 use?

The iPhone 13 series supports 20W charging, just like the iPhone 12 family.

Unfortunately, there is no charger included in the box. The phones only come with an included Type-C to Type-C cable, but no charging brick.
