iPhone 13 Pro battery draining overnight

I have closed all applications. As you can see in the picture, I have selected the range 6-7 pm to show you appilcation usage. There is no allications running between 0 am to 9 am.

I am in France, my carrier does not provide too much details. But last month I consumed 2 GB.

I do not leave my home this week-end, I will have time to check on 13 pro and 12 pro max.

Closing applications does not stop them from running; they will be reloaded if they receive notifications, if they have scheduled updates such as the Weather app, email updates unless all accounts are set to Manual, texts, etc.

And even if the phone is not downloading anything it will connect to the cellular network every few minutes to show it is still online and able to receive calls and texts. If the signal is weak this can use a significant amount of power. So knowing whether it disconnects from cellular data or if the signal is weak during the night the phone can use a lot of power just syncing with the network.

hey, nosleduc, how did your story end? did you return it? did you update to 15.1 and noticed a significant improvement? i have similar issue on normal iphone 13 so i am very interested about your experience. bon courage.

I am facing the same issue. Battery consumes lot of charging overnight. My iPhone 7 is consuming less charging than 13 while ideal. And the issue is at night only. During day time it is consuming comparatively less charge. Please guide.

I have been experiencing the same battery decline overnight issue with the iphone 13. I do not charge my phone overnight and it loses on average 30-40% battery. Is there a better solution than to charge the phone continuously?

As I explained, the absolute best solution is to charge the phone overnight. If the battery is draining overnight there is some process using energy. When you charge overnight the charger supplies that energy, rather than the battery, so the battery rests and thus does not need to be charged as often. And it is charge-discharge cycles that reduce battery life. The alternative is to figure out which app or apps are using the energy overnight.

Nonsense. You charge overnight so most of the energy the phone uses overnight comes from the external power source rather than the battery, which extends the life of the battery because it has fewer discharge/charge cycles over its lifetime. And you get “free” automatic overnight backups, so you can never suffer substantial data loss.

Further, if you DON’T charge overnight all overnight data communications uses cellular data, because Wi-Fi is turned off when the phone is locked and not plugged in. And cellular data is the largest user of energy after the display, especially with a weak or intermittent signal. A 5 bar signal requires 50 MW of RF energy; a 1 bar, 600 MW, thus over 10 times as much energy is required for a weak signal.

Ehhh, I do not think that overnight charging is a bad option in some cases but I KNOW that this is not a cause of draining the battery that nocleduc has.

Everybody knows that overnight charging equals full battery in the morning...

nosleduc said: I had never issues like this with 5g enabled with my iphone 12 pro max

Nosleduc doesn't have the same problem with his iPhone 12 Pro Max so he expects the same with his iPhone 13 Pro.

Maybe he doesn't want to charge the battery overnight because he doesn't have the electrical socket near the bad ;-)

Sooo it is the software or hardware problem, maybe even with weak signal.

I have 2 bar signal during all night, and experienced 5% drop from fe. 00 am to 8 am so it is normal for my taste (I am using iPhone 13 Pro).

But I had the same problem with my old iPhone X a 1.5 year ago.

I erased all data and restored my iPhone X from iCloud and that helped in my case, so I recommend this method first.

We should look for the cause of the problem first. Like a doctor who shouldn't give drugs to the patient until the cause of the disease is not found. So I think it is a hardware problem connected to weak signal during the night

boa noite

também tenho um iphone 13 PRO MAX e também tenho o mesmo problema com perdas durante a noite de 20% a 30%, já fiz de tudo e nada .

Ontem restaurei-o de fábrica pelo Itunes e fiquei só com as aplicações originais e perdeu 15% com tudo desligado .

agora até desliguei a minha conta icloud e retirei o cartão da operadora para ver quanto perde ,já não sei mais o que fazer.....espero que seja do ios 15.1 pois com o ios 15 estava bom.

obrigado

abraço

What will you learn by checking each day of the week? To be meaningful you should also review the list of apps that used energy each night, the number of new emails, texts, notifications, app updates, etc., (and their sizes) that occurred overnight.

While Apple no longer publishes standby time (as no one ever lets their phone be idle for more than a few hours) the last time it was published was 200 hours, which would work out to 0.5% per hour, or 12% per day if the phone was never turned on, did no email fetches, received no notifications, received no push email, received no texts, did not have any apps that updated their content.

Remember, when the phone is not plugged in Wi-Fi is off when the phone is idle, so all of the above updates would use cellular data, and signal strength would be a critical factor.

The bottom line is that battery drain is 100% the result of apps using energy. So the more (and busier) apps that use energy overnight (even when the phone is “idle”) will result in more battery drain. If you can’t (or don’t want to) limit the apps that use energy is all the more reason to charge the phone overnight, in addition to the fact that it extends the useful life of the battery and it provides automatic backup.

but why iPhone 12 Pro Max doesn't drain the battery as fast as iPhone 13 pro in nosleduc's case?

If sth doesn't drain the battery he even wouldn't have to think about overnight charging or not.

Because there are different apps running, different network connections, and, in general, 5G uses more energy than LTE.

Why not just enjoy the phone, rather than think of it as nothing more than a battery gauge?

As I remember he said that he had two phones with the same settings and apps installed.

As an engineer he would like to know the reason for the difference.

Yesterday I turned on airplane mode, just to compare the battery percentage vs only LTE / 5G enabled.

Airplane mode - 2% over the night

LTE / 5G - 5% over the night

I use iPhone 13 Pro.

So it is a normal battery usage during the night without thinking about charging it or not.

Nevertheless your advices about overnight charging with optimised charging enabled are good for battery lifetime, but not everyone can leave the phone plugged to the socket :)

You can also use a wireless charging pad. My wife and I each have one on our night tables. It isn’t as fast as a 20W charger, but, as you’ve got all night to charge it, that doesn’t matter.

But for anyone with serious concerns about extending battery health and preserving data in the event of disaster, overnight charging should be a no-brainer.
