As you may know, the iPhone 13 Pro Max is the current battery life champion when it comes to flagship smartphones. It comfortably lasts longer than anything Samsung, google, OnePlus, Motorola, and Xiaomi has to offer, and it does it with relatively modest hardware (but better optimization).
So the fact that Apple doesn’t even seem to be trying “too hard” with more efficient chips (on paper) and bigger batteries, but iPhone 13 Pro Max is still in a battery class of its own, which left me asking myself a question…
What if the iPhone 14 Pro Max (to be released in September) had the same battery size as the Galaxy S22 Ultra and Pixel 6 Pro? Would it consistently last two full days on a single charge? Maybe even three days, depending on your usage? To answer this question, I’d have to do one of my “favorite” things in the world — math, but also take a look at some of the iPhone 14 leaks and rumors we’ve seen so far, because numbers aren’t. do tell the whole story here.
Apple in a battery class of its own: iPhone 13 Pro Max and iPhone 13 mini battery life is amazing
Apple’s mini iPhone comes with maximum endurance.
To give some perspective to those who are not familiar with it, the iPhone 13 Pro Max has a 4352 mAh cell. In terms of capacity, this is on the mid-range end of the spectrum, as even mid-range Android phones have larger batteries. If iPhone 14 Pro Max gets a 5000 mAh battery, the capacity would be 15% larger compared to Apple’s current flagship flagship and would be comparable to the Galaxy S22 Ultra and Pixel 6 Pro. Pro Max manages to make the Galaxy S22 Ultra last about 25% longer on average (what I mean is there’s 25% battery left when the Galaxy dies). If we compare the iPhone to the Pixel 6 Pro, we see that Google’s most premium flagship has a battery life of more or less 40% than Apple’s. Up to 40%. no typo† As a Pixel 6 Pro user, I confirm and… make a sad face.
iPhone 13 Pro Max lasts 25% longer than the Galaxy S22 Ultra and 40% longer than the Pixel 6 Pro.
This is the exact opposite of what our friend and colleague Joshua Swingle is experiencing. He’s bragging left and right, telling everyone how incredible his iPhone 13 Pro Max’s battery life is, and… he’s got a good point.
The battery life of the iPhone 13 mini is comparable to that of the Pixel 6 Pro – optimization puts Apple and Google far apart
iPhone 13 mini can match the battery life of the Pixel 6 Pro, despite Google’s phone having a 105% larger battery.
Is there a chance that iPhone 14 Pro Max will get a 5000mAh battery and what does that mean for battery life?

Before we get on with the speculations, let’s make it clear that as of now, we don’t know much about iPhone 14 series battery sizes and thus endurance.
However, as recently reported, we came across a tweet from iHacktu iLeak which contains a lot of bold claims about the new iPhone 14 Pro and iPhone 14 Pro Max, such as 35% better GPU and 42% better CPU performance than iPhone 13 Pro. The tipster also cites a “2h10” longer battery life (I assume this applies to the Pro Max model). iHacktu has a positive track record of leaked OS updates, but not hardware leaks, so we’ll take its claims with a grain of salt.
Improved display, chip and battery on iPhone 14 Pro series along with an Always-on display could take iPhone battery to a whole new level
All that aside, it’s worth noting that the iPhone 14 Pro Max’s endurance doesn’t just come down to battery and screen size. Instead, there are a few other factors to consider, which is where other iPhone 14 Pro series leaks and rumors come in handy. This time around, the rumors seem pretty convincing. According to various leaks and rumors from multiple reliable sources, iPhone 14 Pro and iPhone 14 Pro Max are expected to bring:
- Larger batteries compared to iPhone 13 Pro and iPhone 13 Pro Max
- A new and more efficient 1-120Hz display (from 10-120Hz on the iPhone 13 Pro series)
- A new and more efficient A16 Bionic chip, which will still be 5nm, but less power-hungry, just like the upgrade from the A14 to the A15
Leaked iOS 16 Always-On-Display Feature Expected to Debut on iPhone 14 Series: Is It Good or Bad for Battery Life?
An additional thing to note here is that the iPhone 14 Pro and iPhone 14 Pro Max (and possibly the vanilla iPhone 14 series) are expected to finally receive support for an AOD (always-on-display), which allows you to keep your important information such as time, date, battery percentage and notification badges are displayed even when your screen is turned off.
However, depending on your usage habits, this can positively or negatively affect battery life. For example, suppose you are someone who constantly checks their phone for messages and notifications. In that case, the AOD screen will most likely help extend battery life as this information will always be there and you won’t have to unlock your phone and constantly search for it (which can extend battery life, especially if it allows you to continue using the phone).
However, you might not be one to check the time or your notifications often — let’s say you have an Apple Watch. In that case, the AOD may take some of your iPhone 14 Pro’s battery life without giving you much in return, as it will be a turn on and a little bit of juice anyway – whether you look at it or not.
iPhone 14 Pro Max with a 5000 mAh cell and a battery life of 3 days would (again) Apple forgive me for the Lightning port

Purple would be nice too.
Even if we don’t consider all the possible efficiencies that the new hardware could bring to iPhone 14 Pro Max, Apple’s new flagship should technically be able to get at least 15% better endurance compared to iPhone 13 Pro Max if it a 5000 mAh cell. This means it will last a total of 40% longer than the Galaxy S22 Ultra and 55% longer than the Pixel 6 Pro. But assuming that the additional hardware upgrades on iPhone 14 Pro Max will further extend battery life (as they should), then we might be looking at some staggering differences between the 14 Pro Max and Android flagships – between 50 -65%. Again – that also assumes my wish for a 5000 mAh cell will come true…
Really, it seems only a matter of time now before Apple’s largest (and heaviest) iPhone breaks the 5000 mAh barrier and can potentially send us back in time with an insane three-day persistence (Nokia who?). Will it now be iPhone 14 Pro Max, iPhone 15 Pro Max or iPhone 16? We’ll have to wait for more leaks or September 2022 to tell.
Don’t forget that as the battery capacity of an iPhone increases, the rest of the iPhones in the lineup will also make some gains. Apple is known to measure battery life by extra hours of use (a metric that focuses on video playback), rather than by capacity or screen-on-time. For example, last year Apple claimed 1.5 hours of extra use on iPhone 13 Pro (versus iPhone 12 Pro) and 2.5 hours of extra use on iPhone 13 Pro Max, compared to its predecessor.
Anyway, we’ll keep you updated on all the leaks and rumors surrounding the iPhone 14 series until they go official in September. Meanwhile, you can bookmark our iPhone 14 hub, which should answer all your current and future questions about Apple’s upcoming flagships, which are now less than three months away!
And then… let’s go to the iPhone 15 series with… USB-C. Right?
