Ios 15.1 battery drain

I restart my phone and the battery is normal again.

After the update, I was charging my phone everyday. Now, after restarting my phone, the battery with one day is at 55%.

So, I suggest you do a restart to see if the battery comes back to normal.

Can you a little specific in what you mean 'restart'. I know it sounds like a stupid question, because if you mean switch off your phone and restart, then this does not work. I have slowed down my perishable battery drainage by: enable low power mode , auto lock and auto brightness and disable the background apps. To go back to my old iPhone 6 settings, thus I have in my hands an iPhone 13 Pro Max working like iPhone 6! brilliant

Unfortunately, your wise trick of 'rebooting' did not 'aid' the predicament. I did not comment in my above points: I had switched of Siri, and for every APP I switched off Background Refresh and Mobile Data: again as if I had my old iPhone 6. I will await for 48 hours to see if updates are sent, as it would seem this discussion is relevant many parties.

Okay, now with a little fear, I restarted the phone. Now the battery has dropped by only 1 percent, which is a step forward. And I see that autonomy is a bit better, but not as before. I still think it's a software problem. Maybe it will be fixed after another 2 load cycles and those files that were talked about here will be indexed.

Mail app is definitely problematic. I charged my phone to 94% last night. This morning it was already on 90%. Prior to 15.1 it only used to drop 1% overnight. This morning I’ve had 32mins screen on time of which the Mail app only had 1min and yet it’s consumed 65% of the battery in that time.

Me too, I spoke to Apple support today and after doing their obligatory test, which came back all good, they offered me an appointment at the App Store where I could buy a battery. The phone is only 6 months old, iPhone 12 mini iOS 15.1. I'm not imagining the increased amount of times I'm charging the phone, nor have I changed the way I use the phone. It's frustrating when we don't have access to diagnostic software to check what Apple concludes from the diagnostic reports. It's also infuriating when the only circumstance that has changed is the operating system. The support system, when it comes to battery issues puts the user in a loop where the only way out is to buy another battery. The unhelpful links posted by Apple Support Community are examples of what I referred to in my previous sentence.

Exactly, my five month old iPhone 12 Pro Max, both of my iPad Pros, and an iPhone XS Max were fine. Then I installed iOS 15.1 on all devices simultaneously.

I now get barely 4-5 hours of use on my iPhone 12 Pro before I get the warning that my battery is getting low.

All four devices now have significantly degraded battery life, especially my iPhone 12 Pro and my newer iPad Pro. All at the same time and all coinciding with iOS 15.1.

Fix the problem Apple,

ps. I lost 5% of battery just responding here.

This is a software issue - not a hardware issue.

I thought a new day luck would prevail, unfortunately no good news. I tested by playing a 4.55 minute song where the battery decreased by over 3%, just one song! on a beautiful new iPhone 13 Pro Max. I switched off everything, where there was no background activities ( I will no poor you with all the settings). I was playing HiFi on 15.0.2 and the battery needle did not even flinch. THERE IS A BUG WITH 15.1 Today, I noticed the battery was 'warm'! Can a battery be 'frazzled' by an iOS update?

For what it's worth, I disabled background app refresh and I've seen a massive improvement to the battery. When I left the house this morning the battery was at 98%. Five and half hours later it's at 79%. Hope someone else finds this useful. If a few of us could try this and report back to see if they have also had an improvement. Of course, this isn't a solution or a workaround. Just an observation as to what service may be draining the battery.

I tried a similar trick, by troubleshooting if it was an iOS service, specific APP and/or even having the app icons on the screen. Just to arrange the APP icons on the screen used 2% on iPhone 13 Pro Max!!!

I believe the source of the problem of iOS 15.1 is between the operating system and the APPs. I found by switching off all aspects and deleting folders, I was able to stop the battery drain. I have been at 86% for several hours, now. Not exactly ideal, for when I want to use the basic function such as the phone or mail, where it will drain extremely quickly in comparison to 15.0.2. May be it is designed as an art object to be placed on a pedicel to be seen and not used.

I tried all means, disabling app refresh, turning off almost all location services(except find my) even restoring my iPhone 13 pro max and setting it as a new phone multiple times but no luck, the battery drain is still present. Might down grade to 15.0.2 if it that version is still signed.

Yes me too. I have an iPhone 12 that had 98% battery health. I updated to iOS 15.1 I know have 94% battery health and my battery does not even last the day. It is absolutely an apple software issue. My battery lasted almost 2 days before. Coincidence again that a perfectly good phone goes to crap after a new phone is released and a new operating system is introduced. Same old story. May have to give the Samsung a go if this keeps happening with my iphones

I was able to stop the battery drain, by switching off multiple settings and clearing multiple caches. I left the phone on through the night, with everything closed and with 'zero leaks'. Then, I opened Safari and it sunk like a ship with a massive hole; problem number one for Apple to solve. I then opened an app, and this also trickled a leak; problem two, where some app's are not in a 'ready-state' for 15.1 (they were perfect for 15.0, 15.0.1 and 15.0.2), thus, we need a function from Apple to state if an APP is in a 'ready-state' for a version. I have taken pictures of the battery graphs, showing the dramatic scene!.

After a luxurious time of switching-off settings in many areas, I was able to stop the battery drain. I left the phone on over night and 'no' leak. Fantastic I thought, I have my iPhone 13 Pro Max phone at last. However, the moment I opened Safari the battery leaked like a hole in a ship. Unfortunately, in my opinion, we have four main challenges: 1. Settings in 'Settings' (I have lost the ability for the phone to ring, even though I have the correct settings) drains the battery without stop; 2. Safari leaks the moment you open it; 3. certain APPs are not complementary to 15.1 as they were for 15.0, 15.0.1 and 15.0.2, it would be a nice feature where Apple states if an APP is optimal for the version; 3. Remembering to clear all cache including open pages in Safari; 4. Certain functions that were standard in 15.0.2 need to be configured in 15.1!!!
