Which iPhone Has The Best Battery Life (Updated For 2021)

The Latest iPhones – Battery Life Compared

When deciding what iPhone to buy next, battery life is most likely a deciding factor. No matter if you’re someone who is going to be camping and want other things to think about or someone who uses the phone a lot but don’t always have access to a charger.

In the past years, smartphone companies have started making bigger and bigger phones, which means more space for a battery, but that doesn’t automatically mean more battery life. Bigger screens with higher resolution consume more energy, and phones have gotten a tiny bit thicker, which could be to keep up with the battery life in older models.

As you’ll see in the table below, the battery life has increased in some models, but when you compare them to how much the battery capacity has increased, it proves that the phones are using more energy to do the same thing they used to do on a smaller screen.

I want to focus on Apple’s iPhones today. With the new releases of iPhone 13, 13 Mini, 13 Pro, and 13 Pro Max, Apple has a big lineup of different phones with different battery sizes. Let’s take a look at how they compare.

Some interesting takeaways about the latest iPhone-models

  • Apple has changed the way they advertise battery life since last year. They now share video playback as streamed, instead of wireless.
  • iPhone 13 Pro Max has the largest battery and best battery life. The iPhone 13 and 13 Mini is not far behind though, compared to the iPhone 12.
  • iPhone 12 does a lot better than the 11.
  • The iPhone SE has terrible battery life in comparison to all of the above.

So which iPhone has the best battery life? The iPhone 13 Pro Max.

If you are looking to buy the iPhone with the best battery life in 2021, the iPhone 13 Pro Max should be your choice. If you feel like its screen size (6.7 inches) is too big for your hands, the iPhone 13 Pro (6.1 inches) is a great choice.

Fast charge

Something else to take into account if you’re thinking about buying an older model like the iPhone 7 or 7 Plus is that since iPhone 8, all iPhones released support something called fast charge.

This makes it possible to charge your phone from 0 to 50% battery in 30 minutes when using the right power adapter. You can read more about that here on Apple’s website.

Take into account that most companies advertise a slightly higher battery life than what users usually see in the real world. I wrote this article to give you a broad overview of what Apple has to offer in terms of battery life.

    Not Smart

      • No, actually, it is not. The pixel can be reflashed with de googled operating systems. From there you can do whatever you want with the hardware. Apple continues to upswell the image of security and privacy all while selling you out from under your own feet. The latest inclusion of on hardware scanning simply provides the much requested back door that governments have been requesting for years, while telling its customers your safe from prying because “we would refuse to give government access to your data” much like they did in China and many other countries. So no, Apple is not more secure, google less, etc. the devil is in the details. You don’t own your Apple hardware. It now owns you.
