One of the biggest upgrades that come with the new iPhone 13 series are just larger batteries in all four iPhone models.

Apple has just provided official battery life estimates for the new iPhones and they are mind-blowing! Not only is the iPhone 13 Pro Max the one with the longest battery ever on an iPhone, the other new models also get huge upgrades, especially in the area of video streaming.

We don't have official battery sizes from Apple, as the company never discloses this information, but we do have credible info about this topic from leaks. So, let's waste no time and look into these exciting changes in iPhone 13 battery life!

iPhone 13 battery life

1-day battery, but OMG! Big improvements!

So far, Apple has not advertized any iPhone as having a 2-day battery life, and despite the larger batteries, the iPhone 13 series will need to be charged everyday for most users.

But the big news is just how much better battery life has become across the range! Of course, the most compromized iPhone in terms of battery life remains the mini model, while the iPhone 13 and 13 Pro will both provide that extra juice to last comfortably through the day, while the iPhone 13 Pro Max can stretch it to even a day and a half off the charger.

iPhone 13 series battery improvements:

iPhone 13 mini delivers 1.5 hours increase over iPhone 12 mini
iPhone 13 delivers 2.5 hours increase over iPhone 12
iPhone 13 Pro delivers 1.5 hours increase over iPhone 12 Pro
iPhone 13 Pro Max delivers 2.5 hours increase over iPhone 12 Pro Max

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

Apple is also providing the following estimates for battery life while streaming video:

iPhone 13 Pro Max — 25 hours
iPhone 13 Pro — 20 hours
iPhone 13 — 15 hours
iPhone 13 Mini — 13 hours
iPhone 12 Pro Max — 12 hours
iPhone 12 Pro — 11 hours
iPhone 12 — 11 hours
iPhone 13 Mini — 10 hours

This is super impressive, and we cannot wait to test it. Basically, while streaming video, the iPhone 13 Pro Max has DOUBLE the battery life of its predecessor. Now that's some dark magic!

And here is more color on iPhone 13 series battery life in this chart below:

*in hours	Video playback (streamed)	Video playback	Audio playback
iPhone 13 Pro Max	25	28	95
iPhone 13 Pro	20	22	75
iPhone 13	15	19	75
iPhone 13 mini	13	17	55
iPhone 12 Pro Max	12	20	80
iPhone 12 Pro	11	17	65
iPhone 12	11	17	65
iPhone 12 mini	10	15	50
iPhone 11 Pro Max	12	20	80
iPhone 11 Pro	11	18	65
iPhone 11	10	17	65
iPhone XR	—	16	65
iPhone SE (2020)	8	13	40

iPhone 13 battery capacity:

*Apple does not officially disclose battery numbers, the numbers below are based on information from battery registrar Chemtrec.

iPhone 13 Mini — 2,227 mAh to 2,425 mAh (198mAh change, or 9% increase)
iPhone 13 — 2,815 mAh to 3,240 mAh (425mAh change, or 15% increase)
iPhone 13 Pro — 2,815 mAh to 3,125 mAh (310mAh change, or 11% increase)
iPhone 13 Pro Max — 3,687 mAh to 4,373 mAh (686mAh change, or 19% increase)

As you can see, the Pro Max model has nearly twice the battery capacity of the mini version, so we're talking about some huge discrepancies in battery life. It is the sheer increase in capacity on the Pro Max model that is particularly exciting, though, and we believe that should convince many people to make the switch to that larger model.

What's interesting is that this year, the battery sizes on the iPhone 13 and iPhone 13 Pro are different. The Pro actually has the smaller battery size, but is lasted to last longer in official Apple estimates above.

iPhone 13 charging speeds

On the charging front, these premium iPhones come with no charger in the box, only the cable. So yes, you'd have to separately purchase a charging brick. Currently, the fastest one Apple sells provides 20W of power, uses a USB-C connection and costs $20.

All four new iPhones also support MagSafe wireless charging at speeds of up to 15W with compatible chargers.
