iOS 13.2.3 battery drain

I solved this issue on my phone. There were a number of apps open in the background when I upgraded to IOS 13, and they remained open. Force kill all of the apps, and then do a hard reset on the OS. Seems to be working fine now

Yep me too did same as you on 7 plus and iwatch 0 and lasted 1 day and went back to at 7am this morning after charging both fully to 100% at 10am with phone sitting in my desk with wifi connected phone ya siren to 53% and watch is 10% , ridiculous when they both still used to have above 50% before charging again each evening prior to the 13 updates, come on Apple 🤔☹️

I said exactly the same this morning U feel like he would be so disappointed with the direction Apple has taken since he passed, it’s all about marketing, sell sell sell . I know they have to make a profit but the old “bums on seats” is how you play the long game , not making the quick buck , I Love Apple products/IOS but I’m not going to be manoeuvred into buying a new phone while they mess us around. I hate to say it but falling out of love Apple 😔

I have the very same problem after updating to ios 13.2.3. Within half an hour I have lost 20% of power which was never the case before. (Device: iphone 6s plus 64 GB) It is definetly not sustainable like that. What is the purpose of operating the operating system if it is constantly works against your phone's overall performance?

I had a bad time with my iPhone 7 when I first downloaded 13.2.3 but after a few days it went back to normal. I think it had something to do with me backing up to iTunes but I can't be sure..Also I kept it turned off and charging all night for a few days.

I saw on the internet that apple starts stopping the support on most iphones if they are from older generations and my sister was having the same problem too. she has the iphone 8 and im surprised that they already stopped supporting it if the rumour true.

There is a third (and more likely) possibility: Battery health is showing correctly and the phone is draining the battery by some system malfunctions.

From the earlier posts and from friends experience I rather doubt the battery level indication (see above report of an iPhone running for five hours on 1% indicated power).

In general the problem with my iPhone seems to have gotten a bit better. But I still have some downward steps in my battery level graph, so sporadically it still eats up power (and can get quite warm).

I have found another cause for battery drain after upgrading to IOS 13.2.3. I upgraded from IOS 12 to 13.2.3 and noticed the big battery drain. It would go down about 20% overnight if it wasn't on the charger, even with the low battery option set and nothing running according to the battery meter. It would also go down about 8% per hour during the day, even with light use. I tried all the other suggestions to fix battery drain problems, including backing up the phone to iTunes, wiping it completely, and re-installing everything from iTunes, but nothing worked.

It turns out the the problem is was with the mail application and a Microsoft Exchange account. I have five Exchange accounts defined to my mail app and only one of them was having the problem. I discovered this because I run my own MS Exchange 2013 email server and I noticed that the mailbox database logfiles suddenly were growing very quickly. I didn't put it together with my iPhone upgrade until I happened upon this blog entry describing the problem:

http://www.tech-corner.org/go/2015/08/exchange-2013-rapid-log-growth/

This fit my symptoms perfectly, including a recent upgrade of the IOS version on my iPhone. I followed the procedure described in the article, which consists of deleting the offending Exchange account from the iPhone (and all other devices that use ActiveSync, such as iPads, and other brands of cell phones and tablets), then disabling and re-enabling ActiveSync on the email account on the Exchange Server, and lastly re-adding the Exchange account to the iPhone. After doing all that the battery drain ceased.

So if you are having unexplained battery drain issues after upgrading to IOS 13.2.3 and none of the other solutions have worked, and you have Microsoft Exchange Email accounts setup on your phone (you would typically only have this kind of email account if you have an employer provided email address setup on your phone), this might be your problem. Unless you are running your own Exchange Server, you will need someone in tech support at your employer's business to assist you, as this fix requires taking actions on the Exchange Server in addition to the iPhone. The tech-support people may not have noticed the increased database logfile growth if it's a big organization and only a few people have encountered this problem. It didn't affect my iPad, so the problem isn't a certainty after upgrading.

One thing you might try before contacting tech-support to see if this might be the problem, is to first charge up your phone to full before going to bed, then leave it off the charger overnight to see how much the battery depletes when it's not being used, and if it's significant, say 15-20%, then the next night charge your iPhone to full again, and then write down your settings for your Exchange email account, including the password, and then delete the account from your iPhone. Again leave the iPhone off the charger overnight and compare how much the battery depleted overnight versus the night before. If the difference is significant then you may have the problem. Then in the morning re-add your MS Exchange email account to your phone using the settings you wrote down the night before. All your emails, contacts, tasks and notes should reappear after you do this. If difference in the battery drain was significant then you need to contact tech-support at your office and I'd suggest emailing them the link included here, as they will know what it means and how to do it.

I have 6s plus and 13.3 does NOT help with battery draining problem. I absolutely will delay/stop my upgrade to the new iPhone. Hope Apple will fix it soon.

In the meantime I'm going to buy a cheap Androids phone to use. I'm not waiting for Apple to fix this problem. I don't think it is a high priority issue (even it almost stops us to use their phone) in their list unless many people/news organizations/social networks know about this problem, we will have to wait for a longtime.

Just go out and buy a strong power bank and take it with you and your iPhone (if needed).

For me, a cheap Androids phone is a must. Why ? can't wait, don't like power bank, have a plan B if Apple phone has a problem and who know what will come next after 'battery draining'. Cheer - it's just a cell phone.

I just updated recently, as well, with my 6+. I went from 100% to less than 10% in 3 hours with very limited usage (I was reading a book).

This is almost unusable and a crock of poop if they aren't going to address it.

since most recent update. - interesting/annoying variation this morning: woke up to plugged in iphone7 with no charge; pulled out and re-inserted charging cable, and it showed 100% within minutes!

Meanwhile, it has been suddenly dying, not holding charge intermittently since updating to iOS 13.3. Wants me to update again!!

@jmgarrity, Oh please update again! and again!.

It is so sad. I love Apple and Apple products until now. I want a plan B - Androids - a backup plan because I'm afraid of Apple iPhone. Their software code is so complex now due to all features.

Let's me add some annoying variations. After 13.3, my 6s+ went down to 3%. I turned it off (power off). Then turned it on again. It went back up to 77% right away, then went down to 55% in few seconds. After 2 hours, it finally went down to 3% (I have all screens captured to prove it - Judge Judy).

I think when they touch somewhere else in their codes, this is the side effect.

Glad it worked for you. iOS 13.3 did nothing for me (nor my wife's iPhone). Unreal that the battery level indicator doesn't work now; if a person can't trust that then what are we supposed to do - walk around with a bunch of external battery packs? The iPhone is supposed to be a "mobile" phone. I'm hoping this starts to impact Apple's stock price. Maybe Tim Cook will pay attention to it then.

I've been suffering with battery draining issues on my iPhone SE since blindly jumping across to iOS 13. The only improvement I managed to make has come from a factory reset and clean install of fewer Apps at the same time as stripping Location services right back to a minimum, turning off background updates, lowering screen brightness, removing widgets, turning off raise to wake etc. This made my phone barely usable without being continuely tethered to a mains supply or powerbank, even after updating to 13.2.3. My iPhone battery health has been and still is 97% and since having these issues I've been careful to only charge my phone to 80% with periodic recharging to 100% due to the apparent increased need to recharge my phone. I also had instances (like others) when I first upgraded to iOS 13 where the indicated battery level would drop off a cliff down to 1% and on one occasion I left it for almost 24 hrs without plugging it in! Anyway I've now taken the plunge and updated to iOS 13.3 after much deliberation and the results so far are very promising. After updating this morning I left the phone to fully recharge to 100%, so from 7:15am this morning to 1pm the same day, whilst listening to Apple music on my ear pods for my 40min journey to work and light use (including a short phone call) at work my indicated battery percentage is still 90%. I hope this helps you and others to find a solution to the apparent battery draining issues, if updating to iOS 13.3 alone doesn't fix the issue.

Glad you’ve found something that works a little bit.

I’m still having issues after the 13.3 update and I don’t have a lot going on my phone. Within a couple of days my battery health has dropped in percentage And this morning I went from 100% charge to 37% within 1.5 hours and I was at home, on WiFi, on one website. I had my battery checked this last weeks and it failed the test they run and I was promised that a new battery would solve the problem. However, from some of the feedback here it doesn’t, so I don’t know if it’s worth it.
