iPhone 7 Plus with iOS 13.4 battery drain problem

Mine is an SE and has been a pain in the rear for over a year, battery life of 40 mins at one point.

if not already register for the beta test software and try upgrading to 13.5 beta 3 which will initially cause high cpu but mine settled back to a normal phone in 4 days. I have no intention of upgrading further until I know it actually works.

Once you start looking into this the net is full of consumer reports about the battery bug. Only Apple support want to tell you that you’re the first person ever to report this. And then they give you all the crap about resetting and other completely useless things.

All my Apple devices were absolutely fine until the iOS 13 update.

Restoring from a backup will reinstall the same bugs you had when you backed it up. To resolve software related issues the way you're thinking of, you'd need to set it up as a new iPhone after a factory reset. If it's a bug in iOS 13.4.1, which I think it is, then this won't help either. I have an iPhone 8 and XS Max, and my wife has an XS Max, and we didn't experience any of these battery problems until 13.4.1. I did the reset on my 8 and it didn't solve the problem, so I restored it. I have been working with Apple Support to try and find out what's causing it. It's not a rogue app or anything like that. I've followed all the precautions to slow battery drain, and nothing seems to help. My concern, which I don't have benchmarks to look, but my concern is that perhaps there is a bug in the "performance manager" feature that was added in iOS 12, which may be causing the CPU to draw too much power from our iPhones, due to overclocking or something like that. I also read there was an antenna update in 13.4.1 and so it's also possible those radios are drawing more power to increase the range or speed of signals, but I have the batter drain even in Airplane mode, no sim card in and just on wifi on all 3 devices. So, if that part of the update effected wifi antennas then that makes sense, but the only way to fix it then would be another update, which the Apple Support team had no information about. I have a feeling it's that radio update, because people had been complaining about weak signals. Stronger radio signal unfortunately equals faster battery drain. If anyone else has this issue, please contact Apple Support. Let them perform a remote diagnostic and if they gather enough info from our devices, they can then identify the problem and hopefully fix it. Thanks!

You know my 8 is still draining pretty quickly too but my XS Max is better than 13.4.1. My battery health is at 95% on the 8 and 97% on the XS Max, but if it’s just on standby the battery is ok in both. Just the screen on time is not good as previous iOS versions. I think maybe display drivers got messed up on 8 because it looks like lower resolution now to me but I could be wrong, and also it charges slower now. Not sure what’s going on, only that updates are killing my $800+ phone. Apple...what’s wrong with iOS13?

My XS Max has 96% battery health but it's basically glued to its wireless charger... I mean last night I was out and I had to charge it with my external battery pack that I carry for emergencies... I mean... I shouldn't need that just for daily use... Normally I'd have 30-40% left at the end of a night which could make it overnight again and I could still have 2-4 hours of use..

The phone gets to 45% battery still within about 3 hours of LIGHT use. It's driving me nuts. I've always tried to get my Android friends to switch to iPhone but for the first time since the iPhone came out... I'm honestly thinking I might just need to switch... or sit here for another month waiting for an update that we aren't guaranteed.

I've had problem after problem with the all of my Apple products minus my Watch *knock on wood* recently.

Yeah I have only good things to say about the computers and how the ecosystem works well, but I don’t like my 3 year old phone getting battery battery drain like mad! I think I know what they did. I think they boosted the power to the radios to solve connectivity issues people were having. That is NOT necessary on every model. My 8 definitely doesn’t need it. So I’m not happy either.

My Original Se was eventually sorted after over a year of being useless witness the upgrade to 13.5 beta 3 and even then it took 4 days before it settled down to being a phone again. Right now I’ve got 64% after about 9 hours. No way am I upgrading to 13.5 full until I know it’s working properly which it isn’t yet.

yeah it seems like the top 10% goes down really really fast then it slows down a little bit once it gets down closer to 80% and I’m a fan of the original SE I heard the 12 is supposed to have a similar design and if it weren’t updates screwing up my batteries I would have potentially contemplated getting the 12. But now maybe not, because they will just break it with updates later. Why don’t these companies just sell a finished product? We should not have to deal with stuff like this...and as for that android comment they break their phones with updates too. I think I’ll go back to a flip phone 🤣😂

After your comment on my post today about charging my iPhone more, I see that you've been downplaying the existence of this bug for two months now.

I understand you are a fan and avid user but all software has bugs.

We know how to charge our phones. At least most of us.

I just don't understand why when people post about a legitimate bug on here, there are always 2~3 people that shoot it down like it doesn't exists.

That type of behavior is not constructive. It's destructive. It's destructive towards the end user and also towards Apple who may end up being contacted en masse about an issue. If a legitimate issue is covered up or downplayed, it will not be addressed.

Summary: thousands of iPhone and iPad users across the entire lineup of compatible devices for the relevant iOS version have been reporting battery issues stemming as far back as 13.4 but with most of them from 13.4.1. The bug carried over into every Developer Preview beta of 13.5 as well as the RTM 13.5 that most of us now have installed on our devices.

Thousands of iDevice users across the entire lineup of compatible devices have been reporting battery issues going back to iPhoneOS 1.0 and every update since then. Contact Apple Support, ask for a second tier support person and volunteer to put a battery profile on your iPhone and maybe they can determine what the issue is.

This is not constructive either. I've had almost every device since iPhone OS 1.0.

Here's the difference deggie: In 2007, if there was a bug like that, it tended to get addressed within a few weeks. Minus Antenna-Gate and Bend-Gate, things were usually addressed one way or another.

That changed when there were problems with iPhone 6 and 6S batteries and Apple was slowing down the software (that is currently being "settled").

The issue is the firmware. Please do not talk down to me or be passive aggressive.

tldr: XS Max iOS 13 -- perfect battery. iOS 13.4.1 update -- immediately problems until today. Firmware issue.

Sorry, but I go back there and even further to iPods. And not it did not always get addressed within a few weeks for everyone. They were just fixed for you so you didn't care if other people still had problems. But also as time has gone on the OS has become much more complex and the permutations of possible software combinations is almost unfathomable.

What "firmware" are you talking about? iOS is software and is the operating system. I'm not have the problems you talk about on my iPhone 11 Plus Pro. The person I gave my XS Max to is not have battery problems, not on 13.4.1 and not on 13.4.5. Oof if is is a bug in the OS why is it not affecting me? Why is it not affecting my friend.

I was 12 years old when the iPhone came out, deggie.

Nope, I certainly cared if other people had problems :D That's why I helped people on this forum back then too just like you! Except I never continued on here because I forgot about it.

Maybe you are unaware that iOS devices run both firmware and software. I put my XS Max into DFU mode (that stands for Device Firmware Upgrade) to attempt to clean install iOS 13.4.1 and resolve this issue.

If there is a bug in a piece of software or firmware, there are many variables that can affect whether this bug manifests. Maybe it's a bug with a certain app. Maybe it's a certain API. Maybe it's related to how the device's modem is interacting with cell towers and low signal may be drawing more battery. There's an infinite number of reasons why it could affect me and not you. But it's affecting thousands of people on this forum and you can find those people and how they either commented or clicked the button that said they "have this problem too".

I plan to contact Apple and demand a new battery. But this problem did NOT exist BEFORE 13.4.1's install so it does NOT make sense that it is a hardware issue. It happened as soon as the device restarted from installing the (very small) 13.4.1 update from 13.4. So unless the update damaged my battery, it's not a hardware issue.

I never said it was necessarily a hardware issue. You run a battery profile on a device and then submit the files so that programmers can see exactly what is happening with the battery and when and what processes/apps are affecting it and how much. If they see that one of your apps (or more) are conflicting with the OS then they can either rectify that in an update or notify the developers that there apps are not behaving properly. This happens frequently with Facebook.

How much programming experience do you have?
