IOS update 12.3.1 now Battery draining

I'm sure there are some people who are. I'm not. Use your iPhone for 72 hours then check Settings > Battery and see what processes/apps are using most of your battery. And check your battery health while you are there.

I checked my battery it said it was fine. I saw the charge plummet from 92% to 50%. I checked under Settings --> Battery and the percentage of battery used by applications was 0. So something is wrong with the latest update.

This question shouldn’t be on Apple discussions because iOS 12.3.1 is a part of the Apple beta program. Apple beta stuff aren’t allowed to be discussed in this forum. You should be discussing this question in the Apple developer forum. https://developer.apple.com/devforums/ .

AND TRY

If it helps - I completely drained my battery, then plugged it in. When it started back up, I switched it off with the slider.

I let it charge completely over night.

I am on 98% now after three days with no use.

Previously my battery drained completely in a matter of a few hours from 100%, with no use at all.

No. This is a user-to-user forum. Apple's participation here is minimal. That's explained in the Terms of Use to which you agreed when you registered.

If you want help from Apple, you can use the Contact Support link at the top right of every page of these forums. Or, see this article:

Apple takes REAL customer complaints seriously. The issue is not a real complaint. It is a problem with your phone, not with any specific version. If it was caused by the version, which is installed on roughly 500 million phones, you would see tens of thousands of posts about it. So first update to 12.4.1 (which fixes a really critical vulnerability) and if you still have a problem either use standard troubleshooting techniques or make a Genius Bar appointment, where they will use those standard troubleshooting techniques in front of you-->Genius Bar Reservation and Apple Support Options - Apple

what You are suggesting is very Apple way of saying. I’m sure everyone has done this. As my previous messages, I have done a lot of experiment with my phone and following up by the adviser, still, the result is nul.. if you could provide some more test or experiment for me to test my phone. I would be happy to hear it. But I’m pretty sure what you are suggesting would be sth I had done in the past...

OK, here's a very simple test. Restore your phone to factory settings and do not restore a backup. Do not add any features, do not log in to your Apple ID or iCloud, and don't create any email accounts. The check your battery performance. If the problem is still present your phone has a hardware problem. Here are the instructions for restoring to factory settings-->Restore your iPhone, iPad, or iPod to factory settings - Apple Support

I am still resisting wiping my phone and still experience ultra fast battery drain in iOS 12.3.1. I have some observations that might be of interest. Along with turning off all background refresh on apps, I have been turning off as many settings as possible and experimenting with others:

• Mail—I disabled push and switched to manual fetch. If Mail is “open” in the background and even with all settings to fetch or push off-battery drain is amazingly fast. Hard closing it on my iPhone X stops the drain. So, don’t use mail unless attached to power?
• Safari-more or less same as mail. Use only when attached to power and keep totally closed when using battery and battery function returns to “normal”
• Spotlight Search-this function has been whacked for me since installing iOS 12.3.1. I have had to resort to using the App Store to open apps. It does not show as draining the battery but I can’t be sure it is not. When swiping down on the screen to use Spotlight, sometimes there is a several second delay and often the icon for the app being searched displays for a flash and then the screen goes blank. Sometimes, Spotlight just churns and does nothing. These two behaviors are strange and I wonder if they are not also part of the perhaps larger problem
• I have removed all apps that needed IOS updates. I removed Facebook as someone suggested since I don’t use it and figured “why not”.

There is something causing conflicts in the iOS-or, a combination of things that are resulting in this super fast battery drain happening in certain phones and not in others.

1. I have read the whole thread. And lots of similar threads going back to iPhoneOS (before they changed the name). Have you?
2. Then whatever is causing your battery drain is something Apple doesn't know about.
3. Then it is time to keep looking.
4. So if your battery is actually failing replacing is not a solution? How about when it starts swelling and pushes your screen out? Is it a solution at that time?

And the diagnostic method of running the iPhone bare for 48 - 72 hours lets the phone do all the spotlight indexing, back ups, etc. to see if the battery use stabilizes. If it doesn't then something is wrong with the iPhone and further testing is needed and you have ruled out that it is a 3rd party app. If it does stabilize then one of the 3rd party apps is triggering it. The hard part now is to find out which one.

Now just wait for the thread to appear that says "iOS update 12.4 now Battery draining". The early posts will ask how you go bak to 12.3.1 which was working perfectly.

I absolutely cannot believe my eyes. A 'level 9' mod has finally just admitted this board is hosted by Apple employees. WOW.

That is exactly why the only advise you will EVER get here is:

1. Reboot.
2. Restore.
3. Visit Apple store.

Period.

Your reading skills seem to be very poor or it could be your memory.

1. He isn't a "mod on this site.
2. People have long posted here that there are hosts of this site who are responsible for decorum (but there aren't a lot of them given the number of people using it.
3. They don't monitor every post, they generally rely on people to make reports to them. They don't keep track of things to report to Apple.
4. There are Community Specialists here that respond to posts that go unanswered for about a day. They generally provide links to knowledge base articles. They don't collect data and report back to engineers.
5. Once in about a blue moon an engineer may look at a thread here regarding a specific problem and may actually contact someone who is posting. But it won't be a thread like this.
6. Anyone who has read threads here, even the many, many threads on battery life that come up with every update, know there have been more than the 3 options offered that you listed but those three are good suggestions.

Period.

This is how the usage has been. But none of these 3rd party apps are the case at all. Because both the times where I did the reset from phone and iTunes I’ve let the phone in standby without installation of any apps for roughly 5-6 hours. During that time the battery drains the same way and under usage it shows nothing.

Yes i had 0 battery issues than I installed 12.3.1 update and now my battery drains and drops VERY fast say it's degraded battery issues in the battery health which is bullcrap because I didn't have that issue at all before the update. Now battery has to be charged after maybe 1 hour total time on it. You can be looking at a site and screen record the percentage bar display drop rapidly while not even charging or scrolling on the site or page you are looking at. It's definitely an update issue because my husband now has the same issue on his brand new Iphone 7 and battery issue. Good marketing scheme to get customers to buy a new battery for their phone or have to buy a new phone SMH maybe time for me to go back to Android if I have to deal with this.

Apple Heres your proof stayed on same page did nothing took screen shots as battery went from 25% to 21% in less 4 mins.

In a strange turn of events my battery drain issue seems to have stopped.. on BOTH my devices. My iPad and iPhone have stopped draining the past few days now. The one difference I see here and all my past screen shots is no Siri Usage this time. Just about 2 days off the charger now and still at 66%. My phone Also shows little usage for Siri, less than the flashlight for the past 24 hours. So I don’t know folks, mine seems to have fixed itself for now..

Here’s something I recently discovered on mine. Even though I don’t have an Apple TV my device always looks for a one under screen mirroring. And couldn’t find a method to disable that. Wonder if it’s a cause for the drain as well. Can’t recall turning it on purposely.
