These 6 iPhones Have the Best Battery Life: Ranked

Charging your phone is really only convenient to do while you're asleep. That could be the main reason why battery life is a top concern for many people when purchasing a new phone. Additionally, your phone is your lifeline in certain situations, so it can put you at risk if it frequently dies.
Apple prioritizes improving the battery life of iPhones every year. However, even though battery life gets better as Apple products evolve, you can still take preventive measures to ensure the power your phone holds will withstand the test of time.
To maximize battery life and lifespan, Apple has some suggestions on its website, including updating to the latest software and enabling low-power mode.
If you're looking to upgrade your iPhone but want to ensure you have one with an impressive, long-lasting battery, read on to discover which six iPhones have the best battery life.
iPhone 12
Last year's standard iPhone 12 model is a great phone to consider if you want a solid upgrade and good battery life. Although it doesn't have the best battery life in iPhone history, it still holds its ground. Plus, it isn't far behind the next phone in this ranking when it comes to battery capacity. The iPhone 12 Pro battery capacity is actually equivalent to the iPhone 12.
- Battery Capacity: 2,815 mAh
- Screen Size: 6.1?
- Weight: 5.78 ounces (164 grams)
iPhone 13 Pro
The iPhone 13 Pro packs power. It also has ProMotion display, which acts as a battery-saving feature since it can also go as low as 10Hz when needed. So although it does have less battery capacity than the iPhone 13, it could last longer in certain situations.
- Batter Capacity: 3,095 mAh
- Screen Size: 6.1"
- Weight: 7.19 ounces (204 grams)
iPhone 13
Surprisingly, the iPhone 13 has a slightly larger battery capacity than the iPhone 13 Pro. The two phones also share the same screen size, so if the battery is what you're most interested in, you might want to get the regular model, especially since its starting price is $200 cheaper.
- Battery Capacity: 3,227 mAh
- Screen Size: 6.1?
- Weight: 6.14 ounces (174 grams)
iPhone 12 Pro Max
Every iPhone Pro Max model is bound to have great battery life, which holds true for the iPhone 12 Pro Max. If you want a bigger display and battery, this is a great option.
Keep in mind that Apple itself is not selling any predecessors of the iPhone 13 Pro Max. You'll have to search elsewhere to find one, such as refurbishing companies like GameStop, or you may be able to get one directly from your carrier.
- Battery Capacity: 3,687 mAh
- Screen Size: 6.7"
- Weight: 8.03 ounces (228 grams)
iPhone 11 Pro Max
Just like the iPhone 12 Pro Max, you can't buy the iPhone 11 Pro Max directly from Apple, as it is discontinued. The decision to stop selling "the most potent iPhone ever released" was basically because it was replaced by the iPhone 12 Pro Max, and Apple saw no need for it anymore.
Still, if you are able to get your hands on this iPhone model, you'll be very pleased with its outstanding battery life, considering its battery capacity is significantly higher than the 3,687 mAh the iPhone 12 Pro Max holds.
- Battery Capacity: 3969 mAh
- Screen Size: 6.1?
- Weight: 7.97 ounces (226 grams)
iPhone 13 Pro Max
It comes as no surprise that the Pro Max model of the newest iPhone boasts the largest battery with the best battery life of any iPhone. Apple wasn't lying when it said this is the most "Pro" iPhone ever. So if you're willing to spend over $1,000 on it, you can see for yourself how the battery outlasts any other iPhone.
It's still important to keep in mind that with the larger and more powerful battery comes more weight. But if you think the impressive new features and massive battery capacity make up for any downsides, it's probably the right choice for you.
- Battery Capacity: 4,352 mAh
- Screen Size: 6.7?
- Weight: 8.46 ounces (240 grams)
