This iPhone Has The BEST Battery Life – By A HUGE Margin…

Apple’s iPhone 13 range is here. But which iPhone 13 has the best battery life? Let’s find out…

When it comes to battery life, bigger is still very much better. If you want solid, reliable battery life, you need to go with a phone that packs in a massive battery.

Modern phones like Apple’s iPhone 13 run a plethora of advanced technology, things like 5G and CPU-intensive applications, and most users are glued to their screens all day long. For this reason, battery life has never been more important.

Especially after the iPhone 12; its battery life sucked compared to the iPhone 11, so Apple has something of an uphill struggle with the iPhone 13. Above everything else, Apple had to bring the iPhone 13’s battery life back in line with the iPhone 11’s.

Thankfully, Apple succeeded with this: the iPhone 13 range has great battery life across the board, thanks to Apple implementing larger batteries inside the phones. But which iPhone 13 model has the best battery life? Let’s find out.

Which iPhone 13 Has The Best Battery Life?

As noted above, all of Apple’s iPhone 13 models boast improved battery life – even the iPhone 13 Mini. Apple says – and this has been reflected in real-world tests – that the iPhone 13 Mini will last around 1.5 hours longer than the iPhone 12 mini.

Similarly, the iPhone 13’s battery life is now very much back in line with what you got on the iPhone 11, meaning it will last all day long with heavy usage and not require a top.

But if you want the iPhone 13 model with the best battery life, you’ll have to go with the iPhone 13 Pro Max. It features a 4353mAh battery, the biggest ever fitted inside an iPhone. This makes the iPhone 13 Pro Max the best for battery life by a considerable margin – it’ll go all day long and then some.

Apple designs its own hardware, its own chipset, its operating system, and many of its applications, with each piece designed to work with the others. This design optimization means that both the iPhone 13 Pro Max and 12 Pro Max drain their batteries less when in use than many other devices. Now that Apple has furnished its new flagship iPhone with a 4352 mAh battery — a size that is comparable to those of other devices in its segment — it is little wonder that the 13 Pro Max has shown remarkable improvement in our autonomy measurements.

With a battery as large as the one Apple’s iPhone 13 Pro Max runs, you’re looking at some of the best battery performance ever on iPhone. The iPhone 13 Pro Max will run with its screen on, constantly surfing the web over 5G for over 12 hours. The iPhone 12 for comparison could only manage 8 hours.

Similarly, the iPhone 13’s battery performance is up massively too: it will do over 10 hours in the same test versus the iPhone 12’s meager 8 hours. The OnePlus 9 Pro is still better, however, with impressive near-13 hours of battery life during our intensive battery test.

The iPhone 13 Pro fared slightly worse than the iPhone 13 Pro Max, it did just shy of 12 hours, but that is to be expected. It uses a smaller battery, after all. Still, that is a massive gain over the iPhone 12 Pro which only managed 10 hours in the same test.

iPhone 13 Pro and iPhone 13 Pro Max make up our most pro iPhone lineup ever with the biggest advancement for our camera system, the best battery life ever in an iPhone, and the fastest performance of any smartphone, setting a new standard for iPhone and enabling incredible experiences never before possible.
