Siri is draining my battery

The percentage that it shows next to Siri, it’s not the percentage of battery life that is lost, it’s the percentage of how much of the battery has been lost, so if it says Siri is draining 50% of your battery, it actually means for those 24 hours 50% of your battery loss was due to Siri, if you were to login to iCloud and use your phone normally, you would probably notice that the drain is not significant but that Siri percentage drainage would be high

If it says it took up 35%, it doesn’t mean it took 35% of your battery, it just means of the percentage lost 30% of that percentage was due to Siri, meaning that if it says 100% Siri drain every day, it could just mean that you’re not doing much with your phone and that that one percent that it dropped from the two hours was caused by 100% of Siri

I've heard that 13.4 is fixing this issue. Installed today, lets see if it's getting better.

Can you still try if the logout, reboot and login works?

Probably because of your Apple Watch Siri being on? Even with no hey Siri.

I was also told by Apple to do a restore from cloud (aka not from a backup). Haven’t tried yet.

I also noticed the buggyness with contacts and messages just seemingly wasting memory and freezing.

I have an 11 Pro and I'm experiencing exactly the same problem. I did reset all the settings and it did not solve anything. After I've turned off Siri completely, my battery life was good again. Since today, my battery life is bad again and according to the battery settings, Siri is eating up battery, even with Siri completely turned off.

This is driving me crazy. Obviously I'm not the only one having the same problem and I'm wondering if Apple is aware of this issue.

Sadly the 13.5.1 update is not the hoped for answer. Even though Siri is turned off everywhere on my phone settings, it is still eating battery capacity, so must be active somewhere, churning away in the background. The odd thing is that the iPhone SE I have for my French mobile account (fat lot of good that has been this year), although seemingly mirroring the settings of my UK iPhone SE, uses less Siri battery but still some. Why Apple cannot put in a simple setting switch: "Siri off ABSOLUTELY EVERYWHERE" escapes me, unless it is being used for more nefarious tracking and spying purposes, than just answering questions and voice activation of apps, etc.

I have been having battery problems for a long time on a new iPhone X and a new iPad. Tech. support said to get new batteries which is ridiculous for new devices which both show the batteries are at 100%. First I shut Siri off completely, then it was mail background activity draining the battery. Set all mail to manual fetch only and now it is Contacts sucking the battery. Contacts are also freezing when I try to use them or update them. I am ready to throw both devices away, it's so frustrating. iPhone and iPad won't sync either, no matter what I do. Can't believe they haven't come up with a fix for this problem yet. I get several emails a day showing that others are encountering the same problems. C'mon Apple, fix this!

I tried this approach and so far it has been half a day without any battery drain. I think you solved the mystery. I did “reset all settings” a few days ago and the problem still persisted. I just turned off icloud sync for contacts. Will monitor for a week and turn it back on just to test.

Thanks!

I have had this issue with my iPad 11 Pro as well. Apple even replaced the device because the battery life was so bad. But the replacement unit has the exact same problem.

I ran a head-to-head test with my iPad mini (2014) and my iPad Pro (2018, received new in December 2019), and the mini trounced the Pro. My guess is that this is some sort of software issue that is in the OS the new Pro runs but not I’m the OS the old mini runs.

I wrote up the results here: https://medium.com/macoclock/ipad-battery-test-surprise-ipad-mini-trounces-ipad-pro-e473f0619e9f

This is a huge embarrassment. When Steve Jobs announced the iPad in 2010, he touted the standby battery life as over a month. Now here we are ten years later and the top-of-the-line Pros don’t even last half that.

I have somewhat improved battery life. I found an article on reddit, I think, about security tokens for iCloud that get defunct. I think what I did was basically log out of iCloud on all (!) devices, delete some strings (don’t remember if via iTunes, directly on the iPhone or elsewhere) and then one after the other reconnected to iCloud again on my devices.

Battery is not back to normal, or prior to the bug, but it lasts a day and if I turn on flight mode it will also last the night with only 20% left in the evening.
