iPhone Substantial battery drain when using Siri

[chris4565]

Hi guys,

I just noticed that Siri is responsible for a substantial amount of battery usage as you can see in the attached screenshots. I used Siri just 1 or 2 times today so the battery usage is not at all justifiable. I read that some users have the problem that Siri drains the battery e. g. overnight. However from some brief testing it seems like in my case Siri only affects the battery when I'm actually using it, just the amount it uses is too much I think. (Edit: Nope, it also drains the battery when I’m not even using Siri.)

I'm running iOS 13.3.1.

Anyone in the same boat and knows a fix?

Thanks and best wishes
Chris

Edit: Wow, that’s strange: I now noticed that „Hey, Siri“ was on even though I deactivated it like ages ago... I now turned it off again. Actually since I started using iOS a few years ago I noticed multiple times that „Hey, Siri“ turned back on automatically. Anyone knows what could trigger this?

Edit 2: For me, turning off "Hey, Siri" solved this problem.

Same thing for me. It’s insane. My battery is dying all the time. I completely restored my phone. I updated to 13.3.1.... and still having issues. I turned off speech dictation as well, and have shut Siri off and still the same issues.

Any help would be appreciated

 

[chris4565]

Sorry to hear that. In my case turning off „Hey, Siri“ did the trick.

 

[Sillybill]

That’s good. Give it time and see if issues happen again. I had a moment where I thought it worked, but not so much. For me it happens at any time during day.. not just night. I have iPhone 11 Max. Issues started about 2 weeks ago. I was thinking maybe there is another app causing Siri to drain the battery but I can’t pinpoint that.

I shut off hey Siri and keyboard dictation last night. Phone was charged to 75% before I unplugged and went to bed. I woke up and phone was dead this morning. As you can see in screen shot the battery life went completely downhill after the charging and Siri was 100%.

I already erased my phone and started from scratch. It did Not help.

Siri is draining my battery.

 

[chris4565]

Wow, that really sucks. Perhaps someone else here has any idea on how to fix that (besides restoring the phone).

Have you guys tried turning Siri dictation off? In addition to the regular Siri setting.

Siri is draining my battery.

Maybe try turning off “Learn from this app” for individual apps? I’m guessing that’s what’s draining the battery when Siri tries learning from other apps.

I’m getting severe battery drain both on my iPad Air 2 and iPhone 11 Pro Max, with battery information screen showing Siri as the culprit. Not sure what to do!

I turn Siri off on my XS Max but turned it on to test battery drain with it while the phone is idle. Charged the phone to 100% and left it sitting idle for 11 hours after which it was still at 100%.

Try doing the same test at a percentage close to 50%. A fully charged iPhone stays at 100% a lot longer even when you’re actually using it.

I have exactly the same problem with my iPhone 11PROMAX and Apple Watch 5. The drain is abnormal. I have to recharge both devices in the middle of the with light usage. I'm going to turn off Siri for now and report later with my results.

Apple should make its %$%* together or I simply "Google" them :-(

looks like turn off the Learn from App function for Siri worked. The only pain was that I had to go into every app and shut this function off. See screenshot examples. As you can see my battery level was fairly consistent last night.

I stand corrected. The issue happened again last night. I’m at a loss. Oh well.

I have my apps set to auto update when new versions come out. Several apps updated and it reset the Learn From App setting to the On position, which is likely why battery is draining again. So I am turning off app auto updates and and i toggled the learn from app back to Off.

Good to know, thanks for the hint.

This is really annoying. Has anybody tried to contact Apple regarding this issue? At least the 13.4 beta has started and I have the hope, that this issue is going to be fixed with 13.4.

So it is “Learn from app” like I suspected. Glad it worked out for you!

Also check if the setting is getting enabled when you update the apps manually. Cuz that would be a major PitA.

My first day on 13.4b1 , I do not see any improvements. I know it is way too early, but as of now I see the same drain.

Not sure if that really happens. Last night some apps were updated automatically and "Learn Form App" was not enabled for these Apps.

So it is “Learn from app” like I suspected.

Can you confirm if you have Siri enabled, but "Learn from App" disabled, that the battery life is good again?

I was just quoting @Sillybill cuz he said it worked.

it worked that one time. I think I noted it above that even after changing how my apps update to manual and keeping Learn From App OFF I am now still having drain issues again. As of now nothing works.

Its like I’m playing chess with the operating system. I get one victory and then bam the system comes back to screw me.

You are misinterpreting the battery data. The percentages are proportions of battery consumption when compared to other apps during that time period. 50% can be a lot but then again 50% can be literally 1 mAh of battery consumption if 100% is 2 mAh. Allow me to demonstrate....

Between 1am and 2am my Music app 100% of my iPhones battery.



Like your Siri usage my Music usage was 1 minute.



Even though Music was 100% of my battery consumption between 1am - 2am the fact I wasn't doing much on my phone mean 100% of nothing is equal to nothing.

Siri did use more than your Golf game and thats common Siri does a lot with Siri suggestions, and its AI usage throughout apps like Safari, Messages, Sharing window, Spotlight, Parked Car using Bluetooth and GPS, etc etc etc.

Your battery drain overall is a fairly linear line as it drops which means Siri wasn't using much more battery then when she isn't being used.

Also consider the time. Even if Siri maxed out every single iPhone resource (CPU, GPU, GPS, BT, LTE, Wifi, etc etc) battery consumption would be negligible if Siri only did that for 1 minute out of your entire charge cycle. But we know Siri isn't maxing everything out and therefore logic should indicate that its impossible to have "substantial battery drain" with a usage time span of 1 minute.

I didn't misinterpret the percentages. I know that it's proportional. But: I think it makes no sense that using Siri for just 1-2 commands + Siri listening for "Hey, Siri" drains the battery more than twice as much in 1 hour than playing an always-online game for 7 minutes.

Also if you have a look e. g. at posts #5 and #9 clearly there's something wrong with the Siri battery usage.

Since when do you have this issue? I’m still at 13.2.3 on all my daily driver devices and my old iPad Air 2 on 13.4 beta 1 and no issues at all with Siri.

 

[chris4565]

I can't say that for sure because normally I don't have "Hey, Siri" enabled and I just noticed the battery drain problem at the end of January and then I also saw that for whatever reason "Hey, Siri" was automatically switched back on. And since I disabled it again, battery usage is fine again.
