Battery LifeBattery life of the new iPhone 12 series has been quite controversial. This is due to a couple of reasons, but primarily due to the fact that Apple has reduced the actual capacities of the batteries this generation. The new iPhone 12 and 12 Pro come with a very conservative 2815mAh unit, which is less than the 11 Pro’s 3046mAh or the 11’s 3110mAh capacity. It’s extremely unusual to see battery capacities regress like this, particularly in a time where the Android competition routinely use +4000mAh batteries. Apple does have a huge SoC efficiency advantage, but that only goes so far to bridge the battery capacity deficiency for the new iPhones. Another controversial aspect is the 5G connectivity of the new devices. This generation, Apple made the move back to using Qualcomm modems as Intel seemingly wasn’t able to supply them with a satisfactory 5G option. Last year, Apple had purchased Intel’s modem division for $1B, but it’s likely we’ll have to wait a bit more to see the vertical integration of that acquisition. iPhones in the US are the only models which also feature mmWave connectivity, as the rest of the world “only” gets sub-6GHz variants. Unfortunately the models I have for review here are European and mmWave isn’t an option, and I also don’t yet have any sub-6GHz 5G coverage in my area yet, and as such, I can’t really comment much on the cellular battery life of the new phones.  That being said, in our regular Wi-Fi web browser test, we’re seeing very good results for both the iPhone 12 and 12 Pro. Although the 12 Pro has a 7.5% smaller battery and a larger screen than the 11 Pro, it lasted only 3% less than its predecessor, meaning that the SoC and display power efficiency gains this generations were enough to mostly counteract the smaller battery. The iPhone 12 lasted 11% less than the iPhone 11, but that was quite expected given the 10% smaller battery and also the move from a low-resolution LCD to a higher resolution OLED panel. At 12.53h it’s still an absolute excellent result. Apple’s decision to stick with 60Hz panels this generation, while not great in terms of fluidity of animations compared to other competitor devices, at least made a lot of sense for the battery life of the phones. 120Hz really only makes sense on the newer Note20 Ultra with its new “HOP” panel, but even that has some quirks here and there. I expect the iPhone 13 generation to finally embrace higher refresh-rate displays, once all the power efficiency concerns have been fully resolved. Overall, the new iPhone 12’s battery longevity looks to be in line with last generation’s devices, especially comparing 11 Pro vs the new 12 Pro. While 5G remains a wildcard, especially for US users which are on mmWave carriers, it’s always something you can disable, even though that’s a suboptimal option to resort to.

If you're trying to decide which iPhone 12 to buy, battery life should be high on your list. We've run all of the new iPhone 12 models through our battery test, and the results are mixed. The iPhone 12 mini is the smallest of the bunch and has a small battery to match, turning in the shortest runtime over 5G. The iPhone 12 and iPhone 12 Pro lasted longer but are a step behind competing Android phones.
Based on our tests, the iPhone 12 Pro Max is the one to get if you want the longest endurance and fares well against Android phones. It doesn't quite break the 11-hour mark to land on our best phone battery life list, but it's close. iPhone 12 battery test: How it worksHere's how the Tom's Guide battery test works. It surfs the web continuously at 150 nits of screen brightness, launching a new site every 30 seconds until the battery drains. For the iPhone 12 and iPhone 12 Pro, we ran this test over 5G and 4G, and the difference was pretty dramatic. While it's not the only factor, we've included the size of the battery for each phone listed below. The iPhone 12 and iPhone 12 Pro battery sizes are based on certifications and teardowns, as Apple does not list battery capacity as part of its specs. iPhone 12 and iPhone 12 Pro battery test results
iPhone 12 mini battery lifeThe iPhone 12 mini has a small 2,227 mAh battery, so it's not a big surprise that this phone lasted only 7 hours and 28 minutes on our web surfing battery over 5G. The iPhone SE 2020 lasted a considerably longer 9:18 with an even smaller 1,821 mAh battery. However, we conducted that test over 4G, which uses less power. iPhone 12 battery lifeThe regular iPhone 12 lasted just 8 hours and 25 minutes over AT&T's 5G network. Last year's iPhone 11 lasted a whopping 11 hours and 16 minutes over 4G. To compare, we switched the iPhone 12 to 4G-only, and it endured for 10 hours and 23 minutes. Samsung's Galaxy phones generally last longer on a charge over 5G, though they lose a lot of juice when their screens are set to the faster 120Hz refresh rate. For example, the Samsung Galaxy S20 lasted 9:31 on 5G but that dipped down to 8:04 at 120Hz. Google's Pixel 5 was nearly an hour better than the iPhone 12 at 9:56; it dropped to 9:29 with the screen set to a faster 90Hz refresh rate. Both of those times are well ahead of the iPhone 12's 8:25 result over 5G. iPhone 12 Pro battery lifeThe iPhone 12 Pro fared a bit better, lasting 9 hours and 6 minutes minutes over T-Mobile's 5G network. That runtime jumped to 11:24 over 4G. The iPhone 11 Pro lasted 10:24 over 4G. The similarly priced Samsung Galaxy S20 Plus lasted 10:31 over 5G, which is nearly 1.5 hours longer than the iPhone 12 Pro. The runtime of Samsung's phone dropped to 8:55 at 120Hz, which is slightly worse than the iPhone 12 Pro over 5G. To be fair, the Galaxy S20 Plus has a larger 4,500 mAh battery, while the iPhone 12 Pro is rated for 2,815 mAh. iPhone 12 Pro Max battery lifeNow we're talking. The iPhone 12 Pro Max's 3,687 mAh battery lasted a very impressive 10 hours and 53 minutes over 5G. That beats the iPhone 12 Pro by nearly two hours. The Galaxy S20 Ultra with its much bigger 5,000 mAh battery endured for 12 hours and 3 minutes, which fell to 9:13 in 120Hz display mode. iPhone 12 battery life: Bottom lineOf course, our web surfing test is just one way to measure battery life. And we know that no one is going to surf the web for 10 or 11 hours straight. But this test does give us a way to compare endurance across multiple phones, even if it is a taxing test. When you're not surfing the web, the iPhone 12's Smart Data mode can automatically switch to 4G to help save battery life. But this only kicks in during certain scenarios, such as when you're streaming music with the screen turned off. Overall, the iPhone 12 and iPhone 12 Pro battery life is a bummer over 5G, at least when surfing the web. So you may want to manually switch to 4G in some cases to save extra juice.
