I am frustrated with the autonomy of my iPhone 16 Pro Max. I also was frustrated with the same issue with my iPhone 14 Pro Max and 15 Pro Max. With the same use behavior, the autonomy was never like 13 Pro Max. How is that? Why is it happens? Someone has the same issue? I tried using the phone as a new device without putting an iCloud or iTunes backup. Same thing.

Like 8am til 10pm of constant usage? Yep fine. As already asked, a screen shot of the battery usage graph taked at bed time will help us to help you.
11% home & lock screen? turn off raise to wake (display settings) and Tap to Wake (accessibility)
Make sure you turn on optimised charging and turn OFF 80% charge limit, charge overnight to 100% every night.
What do you mean with battery autonomy?
Press and quickly release the volume up button.
Press and quickly release the volume down button.
Press and hold the side button.
When the Apple logo appears, release the side button.
80% max is more myth than truth and applies to cars more than phones. There is more truth in optimised charging, but generally usage is the key ageing factor. With heavy usage you need 100% in the morning, same as drivers of electric taxis would choose to start with a full battery in the morning.
Loss of 60% in 2 hours would not match yesterday's graph but unexplained loss could be faulty battery so...

How long is the battery lasting until you need to recharge it? If you go to Battery, then scroll down and look at the apps that are using the highest percentage of battery, what are you seeing?
There is nothing wrong with 17 hours. But I guarantee that 38% usage by WhatsApp is definitely having an effect on your battery.
The battery lasts about 17 hours (it is less than 10% at that time).
Right now, with about 8 hours since I disconnected from charger, in Battery the apps using the highest percentage are: Whatsapp 38%, Home & Lock Screen 11%, Safari 7%, Spotify 6%, Mail 5%, Telegram 5%, Photos 5%, X 4%....
Thanks. But I recalculated the time you asked me: is less than 14 hours. It is still right? As you see in the list of apps and battery usage, I don’t play videogames and I barely watch videos.
I would like not to use Whatsapp but is the most popular app of its kind in my country.
It is not with constant use. As an example, today with 80% limit, I disconnected the phone at 7:30 am, it was in my pocket a third of the time and at 9:30 pm it was at 21%. I recorded just 2 minutes of video and toke a few photos. The rest was Whatsapp, social media, Safari.
I believed that the 80% limit was good to battery health. It is not?
You said "today with 80% limit, I disconnected the phone at 7:30 am, it was in my pocket a third of the time and at 9:30 pm it was at 21%" = 59% loss, which is a huge drain indicating maybe a leaky battery, but it would show up today, which it didnt. But check anyway.
Autonomy means self determination or self government. What is the issue? If you’re not a native English speaker it’s fine to use your own language. 😀
You are a very nice guy…
I think you understand what autonomy means in this case.
Hi. I mean battery life, the time since I disconnect it from the charger in the morning until I have to recharge it because it is about to turn off.
I already try what you told me in your reply.
Thanks. I will try that test.
What do you mean by: “Loss of 60% in 2 hours would not match yesterday's graph but unexplained loss could be faulty battery”?
Do you see that loss on my graph?
Ah didn't see the pm, I'm a 24hr person , my bad
Ok. But the 60% loss was in 14 hours (been Saturday was much less use than on a working day).
Thanks for all your help and for kindly explain me all of this.
What is impacting the battery life of my iPhone 16 Pro Max?
