Am I the only one with this issue? Yesterday, or the day before that, I updated my iPhone XR. One thing I've come to notice is that, since I updated it, the battery drains pretty fast. I'd say I'm an average user and I could go the entire day and it wouldn't reach 20%. Now, around 4PM, after being fully charged around 5AM, it's down to 50%. I just find it weird, knowing that I'm an average user, my average screentime is around 2 hours a day, so I don't know what's up.
***Sorry, posted too soon. Trying again***
I have been part of the group that has been impacted by severe battery drain of ~1% every 5-15 seconds since updating to iOS 12.1.4.
I tested the options mentioned in this thread, and have found that the issue seems to be related to app data download connections and/or downloading new data on the device (downloading an app from the app store, opening an app that needs to fetch new data, fetching new content by pulling/swiping down to refresh within an app, background app refresh, etc). I have confirmed that this issue occurs in both native apps such as Mail, App Store, Podcasts, as well as 3rd party apps.
Close all apps this did nothing, and the battery continues to drain. If not immediately, on the next background app refresh.
Power cycle (restart) device you can see evidence of some people's theory that there may be something going on with battery percentage calculation. After the battery appears to have severely drained, a power cycle will show the battery percentage back closer to what you would expect the usage to be prior to the draining event. A power cycle will likely still result in the device attempting to fetch new data, and more often than not will resume battery drain
Turn off Fetch New Data (Settings > Passwords & Accounts > Fetch New Data > toggle Push to off) + Power cycle device battery continues to drain
Turn off Background App Refresh (Settings > General > Background App Refresh > Background App Refresh > Off) + Power cycle device At first I thought this solved the issue while I was at work for a few hours in the morning, but when I started actively using my phone a bit more the battery drain started again
Delete Skype for Business + Power cycle device This is where I discovered that the issue is not isolated to only 3rd party apps doing things in the background and adversely interacting with 12.1.4... I tried this because some people indicated that they thought it may be related to Skype. I thought this worked for a while as well, until I opened my native iPhone Podcasts app and it started downloading new podcasts. I then watched my battery start draining at a rate of 1% every 5 seconds (I could hear a clock ticking beside me and timed it)
Turn off Bluetooth + open an app and pull down to initiate data fetch/download connection battery continues to drain
Turn off Wi-Fi + open an app and pull down to initiate data fetch/download connection battery continues to drain
Turn on Airplane Mode + open an app and pull down to initiate data fetch/download connection oddly enough, this doesn't always seem to work in interrupting whatever process is trying to download new data, and in some of my testing the battery would continue to drain.
Turn on Low Power Mode (Settings > Battery > Low Power Mode) + open an app and pull down to initiate data fetch/download connection this has been the only solution that I have been able to use to consistently and reliably keep my battery from draining. If the device is plugged in and charging, it will turn Low Power Mode off once it reaches a certain percentage (89%? 90%?) so you'll need to turn it on again once you unplug
Switch to a different device with <iOS 12.1.4 I have a spare backup iPhone 6S which is still on iOS 12. Apple will not allow me to restore from backup without updating to iOS 12.1.4 so I did not complete this test
Factory reset + restore at this point I did not have the time nor the patience to attempt this, but I did see that it did not resolve the issue for another user
Again, it seems like the only way to reliably stop the battery drain is to break or interrupt whatever connection is trying fetch new data by turning on Low Power Mode. I do have a lot of apps on my phone that I use regularly, which I'm assuming is the reason I may be impacted more than others since there is a lot of background activity happening with each additional app.
-------------------------
tl;dr the battery seems to drain significantly when downloading new data or making a connection to fetch new data (unclear which it is, specifically), and the only workaround that reliably helps is to turn on Low Power Mode (Settings > Battery > Low Power Mode)
Sign up for the Apple iOS beta so you can install iOS 12.2 Public Beta as no battery drain issues currently reported with this release.
I had the same problem with my iphone 8. Then I decided to downgrade to ios 12.1.1 beta 3 “BTW still signed by apple” and now my battery lasts for a full day!
wifi only, bt turned off
Any notification will turn on the screen for about 10 seconds, unless you have Do Not Disturb enabled. If you get a lot of notifications this can add up.
Did you restore the phone to factory settings and install no third party apps and you still get massive battery drain overnight?
Show us the battery stats.
nope....I’ll try a DFU today
hi all,
I've just reinstalled IOS12.1.4 using iMazing
I used recovery mode, not DFU.
let's see the outcome.
have a good one,
robert
12.2 is out now. I’m downloading it right now.
I noticed a significant "fix" after I reinstalled iOS 12.1.4. Now I'd rather wait 24-36-48 hours after upgrading to 12.2 to render my opinion.
what happened when you reset it to factory settings then rebuilt with minimal apps from scratch?
im seeing this exact scenario. i upgraded from 12.1.2 to 12.1.4 and over the past 3 days (since i updated), my battery is almost at 0% by 1pm (before i was good till sleep/bed ~ 10pm). looking at the battery settings, its NOT showing the issue, as the % of usage does not add up to 100% (ie all apps will add up to ~ 60%), even when i tap on the 3-4h segment of the graph at the top, the % do not add up.
so ive now tried fully disabling siri, but the issue persists. (i dont use hey siri, only push home button. i actually dont use siri at all, i just need it enabled for dictation to work).
Clearly something is wrong with 12.1.4
(iphone 7 +)
I am also getting significant battery drain on my new iPhone X and my older iPad Pro since the latest iOS update. My iPad which is left idle during daytime and at 100% power each morning is dead by 6pm
my almost brand new iphoneX is down to 30% by mid afternoon with little use
neither of these devices had these issues prior to the iOS update and neither have had new apps installed. judging by the posts here there’s clearly a battery performance issue that’s been introduced by the latest update
Re
“nothing out of the ordinary on Tuesday, Wednesday or any other day since other than it’s fully charged in the morning, hardly used all day and dead as a dodo by teatime,”
Take a look at Tuesday graph. It shows 6 hours screen on activity which seems to contradict the above statement. Just noticed it.
By complete reset do you mean reset as new? And the battery drain problem went away?
Its certainly a tactic I used several times on my droid phone which actually got warm whilst running down in my pocket. Its amazing how few apps you really need and a good clearout is cathartic.
So you are saying a restore to factory settings (restore as new) with no additional apps installed, the ultimate last resort, did not fix your problem? In that case you have a defective battery and need to go to an apple repair centre.
