iOS 13.5.1 battery drain

Did another test with 4 iPads. Only the top left iPad (iPad 6th gen) is upgrade to 13.5.1, the other 3 are iPad Air 2's that are still on 13.4.1. I've rebooted all 4, waited a while and disabled background refresh, closed all apps, and set them to airplane mode.

The 3 iPads with 13.4.1 are doing fine, 4-10% max. The iPad running 13.5.1 is the only one that uses 40-70% CPU (see CPU graph).

Unfortunately since iOS 12 or so, you're not allowed to view the background processes anymore ('this feature is no longer supported in iOS)

Now obviously the other difference is that the 1 iPad that I upgraded to 13.5.1 is the only iPad 6th gen, but I don't want to upgrade any other right now, knowing it will probably break it as well.

On iPhone SE and iPhone SE it is the same behavior. CPU load stays 30-40% or so.

iPhone XS (13.5.1):

My wife has a 6S with wifi on all the time and a number of apps like whatsapp, Mail and banking, cellular data is off.

It took 13.5.1 OTA on day one of the update.

Battery is 85% max capacity.

We charge it every 4 to 5 days which is the best smartphone standby we ever enjoyed.

Doesnt help you but it suggests other than a universal OS bug, eg a damaged battery

The following shows level after 3.5 days so it could last another 3

Thst's my wife's phone. Just illustrating the background drain can be 6-7 days which contrasts with some of the reports.

My own iphone behaves the same on 13.5.1 as it did on 13.0 onwards. Battery usage matches heavy phone usage.

EXCEPT I installed a Barometer app yesterday . See the light blue background usage. That app is going NOW!

Pity, it was a good one.

So today and yesterday I kept in mind to force shutdown every app and yes, I have the "normal" battery usage.

Wifi, Cellular data and location on. Lots of things running in HomeKit. (Since I've introduced HomeKit, my battery usage is slightly heavier as before, but that's since the first versions of iOS 13.)

Conclusion: a new fresh install of 13.5.1 took a week till 10 days (!!!) to become stable.

The 3 problematic apps keeps running in the background until a forced shutdown.

peter_watt: like your Barometer app, I have 3. That's the problem! I used them as long as I use Apple phones. They never gave problems.

I forgot to shutdown "buienradar" this evening. Look on the light blue bars...

Maybe some "constructive" talking...

As earlier mentioned, iOS 13.5(.1) takes very long time to calibrate. 10 days after the clean install, battery life became normal on my Xs Max. One condition: every time I used them , in my case, Buienradar, iCulture or HLN, I have to force shutdown those apps. If I didn't, my battery drains completely in less than12h.

In the App Store update section, I already saw improvements on battery life for HLN. So far I haven't seen background battery consumption.

Two days ago iCulture has been updated. Indeed, I opened the app an hour ago and no background activity yet.

In the app store, they explained the problem. For who's interested: I add a print screen of the explanation. It's Dutch, sorry, but translations apps will do the magic...

This will be ipadOS 13.5.1

If you are saying it uses big % of battery when shut down I suggest you have the battery looked at

This is my iPad mini 4 on 13.5.1 where zero usage gives zero battery drain

lol at least the alarm clock app is justified. I work at a fire station and we don’t have clocks in our room when we sleep, so I use that for 8 hours a night when I work to see the time at night. 16% was for about 2 hours onscreen without the phone plugged in (which was unintentional, I usually have it plugged in). This pic is from today and I turned off Siri an hour ago.

Going through the same issue. Seems to have developed after upgrade to 13.5.1. iPhone is 7 plus. Initial support call to Apple thought that because camera app was on in the background and showed 61% battery usage, it was the culprit that totally drained the battery overnight.

Issue continued with total battery drain while in standby overnight. Next step we turned off background App Refresh. Battery still fully drained overnight.

Also had done Factory Reset and then restored from current Backup. Didn’t resolve battery issue.

See pic showing battery drain

Next test step, which will be unwanted, will be to do Factory’s Restore and NOT DO A RESTORE FROM CURRENT BACKUP. Let that go for a day or two and see what happens.

I might contact Apple Support again to see what they think given initial determination has not resolved the issue.

Going strong. I’m attaching screen shots. So when you do 3 day obviously it’s an aggregate of of the last three days. First day Siri was doing that thing and was at 50-60% usage. But as you can see now. It’s settled down after the settings which I outlined in previous post.

I had to send my old phone back as part of exchange so I’m not sure how it’s doing but I do know it was doing similar after a reset. I’m pretty confident in saying a “Reset all settings” worked for me. But I’d recommend doing a erase all data and manually restoring. Do not restore data from iCloud or Mac backup. It was not as bad as I thought. And yes. It totally stinks that I would have to even do that. But it worked. I’m convinced it was 13.5.1 that didn’t play nice since we are all having the same problem. Not sure why a reset worked but it did.

Same here on two different devices (Ipad Pro 11" and Iphone SE first gen). I barely use apps or my phone. My iphone SE could hold a charge with regular use for 72 hours, now it can barely hold it for 30 hrs with the same use.

My ipad pro drains battery while completely off, as you can see in the attached picture. Right after being charged, I turned it off and the next day my battery showed up at 72%. I also tried discharging my device completely before charging it again but it still occurs.

This is clearly an update bug, thousands of users are reporting the same issue all over the world with different setups. Hope they fix it soon. Will try turning my ipad off while in airplane mode and see what happens.

So I have had this problem since the update. Same issue as reported. But what’s even stranger was the Mail App and Siri who were consuming chunks of the battery, were still active in the background even when I switched Siri off and disabled the Mail App from Screen Time (Content Restrictions). Even THAT wasn’t working! So I deleted my mail app since it was still affecting my battery. I bought my phone in November and I had a 100% battery health till the first week of June. Right after the update, my battery health went from 100 to 94 because those apps kept running in the background. I disabled background app refresh, reset settings, did a factory reset both through Mac and my iPhone, TO NO AVAIL.

I was with Apple support most days, trying to find a solution.

In the end, I did find the solution to this problem but it isn’t going to be a popular solution here.

What I did was restore my iPhone through iTunes and when everything got erased from my phone, I did NOT choose “restore backup from iCloud” and just logged into my Apple ID and started using my phone without Apps being installed.

I, then, downloaded every single App through the App store yet again and this is how I was able to fix this problem. There is no other solution out there. I have tried everything else

Hi Gert, I did my best but after 36 hours that app has used less than 1% and zero background. Night time is zero activity for all apps. Siri and auto dark mode both on.

I did get a rain alarm though.

Background activity on Times Radio was genuine screen off listening.

Everyone can see for themselves. 9 hours later, my battery has only dropped from 80 to 50 because as you can see I was busy downloading Apps from my AppStore and setting them up and rearranging them how I always do. Bear in mind, I have 114 Apps on my iPhone. So downloading and rearranging them took time. Which is why the only thing that took up my battery was App Store and Home & Lock Screen. As you can see there is not a single app running in the background. In fact, I woke up around 3 PM to check my battery status and it was still 80% with everything on. My Mail is now working fine. The only thing I disabled was Siri.

Redownloading Apps isn’t difficult at all, all one has to do is to log into their App Store, go to Purchase History and start downloading Apps. Simple.

No, it isn't.

I use this Buienradar too and that app never gave problems so far.

As promised, when I came home this afternoon, I started and closed Buienalarm. After a while you see the result in this screenshot.

My settings:

-Background refresh: off

-Listen to "hé siri": off

-automatic Light/dark: off (set to always light)

On my 1 month old iPhone 11 Pro battery stopped charging as i upgraded to iOS 13.5.1.

It’s stuck at 57% and battery health dropped to 96%* And it is literraly burning hot. Soft reset and restoring don’t help. And also my hotspot is no longer working correctly, keeps turning off. Becoming desperate
