How has the autonomy of the iPhone changed after installing iOS 16

The new version of iOS has just been released for everyone, and we can already state that not everything is so good with it: many users frankly disliked this version and regretted having installed it. To be honest, I don’t remember such negativity since iOS 11: the current operating system is also damp, although there were pretty flattering reviews about beta versions. However, in the vast our Telegram chat I haven’t seen any reports that iPhones with iOS 16 began to discharge faster On the contrary, they note that they began to work longer. What?! But does it happen? It looks like yes.

How is the iPhone battery on iOS 16?

iPhone drains fast after update

Traditionally, after installing a new version of iOS, many users start having problems with battery life. The problem is extremely rarely widespread – mostly iPhone starts draining faster only some users with completely different device models. It is extremely difficult to predict which update will start to kill the battery: it happens after installing minor updates, and after major versions of iOS with new features that weigh several gigabytes.


iOS 16 could increase battery life? How so?

And so that iPhone started working longer after update, almost never happens: the exception is probably iOS 15.4.1. Remember how this minor update suddenly increased autonomy of old iPhones, and the new ones – slightly worsened? many battery replacement helped., but this was not always necessary. It seems that Apple engineers took into account all past mistakes and created a miracle: it turns out that iOS 16 increases the battery life of iPhones! And this is not speculation, but a fact. See what happened.

Battery on iOS 16

The first beta versions of iOS 16 worked in a rather peculiar way: for example, many users after installing the very first revisions of iOS 16 were faced with the fact that maximum battery capacity dropped by a few percent. Others noticed that the iPhone with the new iOS barely survived until the evening or did not charge more than 60%. Apparently, Apple engineers took into account the mistakes and did the incredible thing – they made iPhones work longer.

Bloggers are not the first to conduct such tests. But this time the results are just incredible!

This confirms the video from the YouTube channel iAppleBytes: the author took all the same iPhone 8, iPhone SE, iPhone XR, as well as iPhone 11, 12 and 13, on which the release version of iOS 16 was installed. To check the battery life, the Geekbench benchmark was used, and for the purity of the experiment, all iPhones were charged up to 100% with manual brightness set to 25%. Importantly, the iPhone 11, 12, and 13 had 100% maximum capacity, the iPhone SE 2020 had 87%, the iPhone 8 had 97%, and the iPhone XR had 92%. What came of it?

  • The iPhone 8 was the first to give up, to my surprise, having worked for almost 3 hours. It turns out that the maximum capacity does not solve anything on the old processor!
  • After it, the iPhone SE 2020 was discharged at around 3 hours and 45 minutes – quite a long time, given the state of the battery of this problematic smartphone.
  • Then, the iPhone XR (5 hours 48 minutes) and iPhone 11 (5 hours 47 minutes) were discharged almost simultaneously. Once again, the iPhone 11’s 100 percent battery capacity made no difference.
  • The iPhone 12 was the next to give up – a smartphone on iOS 16 with a fresh battery lasted 7 hours and 9 minutes.

Of course, the iPhone 13 lasted the longest – 9 hours 4 minutes, which is almost 2 hours longer than the iPhone 12. And what does this mean? iOS 16 kills battery or not?

Should I install iOS 16

At the end of the video, a summary was made based on statistics. And it turned out the following: it turns out that all smartphones, except for the iPhone 8, gave out almost the best operating time on iOS 16. In any case, this is evidenced by the results of synthetic tests. If you did the opposite, then the phone may simply be faulty. It may have problems with the battery or with the power controller. In this case it’s better turn to specialists.

Almost all iPhones have given the maximum battery life. How so?

  • The iPhone 11 and iPhone XR have significantly increased their battery life – this was not even on iOS 14.4, which is reflected in the iAppleBytes chart as the very first.
  • Personally, I was pleased with the iPhone SE 2020: it showed the highest autonomy result – about the same as on iOS 14.4 and 15.4.
  • The iPhone 12 also performed well, giving the maximum battery life for the entire time of iOS 15.
  • iPhone 13 also showed high performance – it only worked for longer on iOS 15.0.1 and 15.0.2.
  • But you won’t envy the iPhone 8 – it showed the worst result since iOS 14.4 – if you own this smartphone, you probably shouldn’t upgrade.

How long does an iPhone 14 battery last?

In another autonomy test YouTube channel Mrwhosetheboss compared the battery power of the iPhone SE, iPhone 12, iPhone 13/13 mini, as well as all iPhone 14 models. The author of the channel launched games, Apple maps, social network applications and a camera on smartphones in turn.

It turned out that the iPhone 13 mini lasts almost as long as the iPhone 12 (6 hours 36 minutes versus 6 hours 48 minutes). The same with the iPhone 13 and iPhone 14 – both worked for 7 hours and 15 minutes. This once again confirms that Apple has once again presented us with the same phone!

The situation with the iPhone 14 Plus is much more interesting: Apple was not cunning when it said that this is a smartphone with the most powerful battery! It lasted 9 hours and 23 minutes – almost 2 hours longer than the iPhone 14 Pro (7 hours 49 minutes) and the same as the iPhone 14 Pro Max (9 hours 31 minutes).

Looks like we were right: “Plus” on the old A15 Bionic processor has really most powerful iPhone battery, like the iPhone 14 Pro Max. The small difference in battery life is offset by the gluttony of the new processor, which is certainly present.

Of course, not a single simulated battery test is the ultimate truth, since each user has his own scenario of working with the iPhone during the day. But it is safe to say that With iOS 16, the autonomy of the iPhone will not be worsethan with iOS 15. Perhaps even better, unless, of course, you have an iPhone 8. In this case, the battery should be replaced by itself. It’s possible do it at a service center or buy it and change it yourself.

It seems that iOS 16 is really good in terms of autonomy and you need to upgrade if only for this. As a last resort, while there is an opportunity to roll back to the previous version: we talked about how to do this in our special article.
