iOS 13.5.1 battery drain

I can’t even see what apps are draining my battery. The battery statistics have not been updated for 5 hours, and the info there is completely wrong. I just got off a FaceTime call and FaceTime isn’t even listed as using up battery. This is the WORST apple update I have ever experienced.

Maybe, I better let it down to create a new topic, because there's no point.

Past night, I didn't connect my iPhone to a charger. Went from 60% till 56% (11PM till 8AM), so still the normal behavior.

(forced closed all apps before I went to bed yesterday)

This morning opened my phone and saw a more heavy battery drain. Although I didn't used any app since last night, a random background activity has started again. Apps who never did it before.

pfff, charging this phone everyday and waiting on 13.6.

It will be available by the end of june, beginning of july. Today they speak about the end of July, beginning of august.

I'm beginning to be dispirited in this matter.

Same issue here with the background app activity even though I have that toggled off. Battery drain has been brutal on my 6s since 13.4 but this is background activity nonsense since 13.5.1 is just crackers. It’s pretty random too which app has the issue, there is no other way to find out unless you test each app one by one and let it ride for a period of time. Only then can you force close and add it to the list of apps you have to remember to force close. This iOS has a major bug to allow background activity/battery drain even though the user has background refresh off. Any assistance in solving this issue would be greatly appreciated.

Iphone XS here, running iOS 13.4.1, have not updated to 13.5.1 yet. Battery drain just started for me about 5 days ago. Have not downloaded any new apps in that time frame. When checking battery usage its is showing 63% use by Apple Music App, accounting for 15h54mins of background use, only 1 min of actual screen use in the last 24hrs.

I also have this problem since the upgrade to iOS 12.4.7 (the most actual for my iP6). I tested it today closed all Apps and disabled the sleep mode. Background light was low and after about two hours the battery was nearly empty. The phone is getting really warm. Too expensive gadget to keep my coffee fresh ;-)

In my case it's always the AppStore which drains my battery. But after reading several posts it seems that's a bug in processing the background tasks. Please fix that asap because the iPhone is a mobile device ;-)

Cheers, Stephan

Updated to 13.6. Appears the rogue background activity I was experiencing has ceased, yet the inexplicable battery drops and overall poor performance continues with my 6s. The old ‘Green Cliffs of iOS’ are still present.

My opinion is that you come across as very rude and unhelpful to members of this forum and edit your comments so that it appears otherwise when called out for it. For example this was your original comment.

When I say off I mean powered off with the slider. Battery losing charge when powered off is faulty.

The advice from Apple for long term storage is to charge to 50% then power off. If there were any background processes that would not make sense as it would go flat, Long term storage with flat battery would kill the phone. I am with Gert in that tour phone does not seem to be "powered off."

If you just mean closed then yes it will use many processes which is why they are designed to be on charge overnight

Power off slider...

I did what Peter and I discussed a few weeks ago. Factory reset/restore from iTunes and no restoration from my iCloud backup. That was on 13.5.1! Then 13.6 got released and my battery life improved even more. With my heavy usage I still last an entire day with quite some battery left in the phone. I charged my phone and took it to the hospital with me and my phone was connected ti the wifi during that 12 hour shift. I only lost 1% in 12 hours. Then I FaceTimed a friend and I slept with 93% battery. Woke up and did some more FaceTiming and iMessaging and now I am down to 78% after 3-4 hours of usage (on and off) whilst being consistently connected to the WiFi.

I suggest you guys do the same. Just my two cents. Sincere advice. Take it or leave it.

cheers!

When your battery is at 30%, switch off your device. Plug in the charger. Let it charge upto 100%. Then you switch on the device. This will clear up certain memory and you are good to go. To be honest in the last 6 days, I have got like 9h of usage per day on average with 70℅ of battery usage. I will attach a screenshot for you to believe. Notice that on 14,15 and 16th July, my battery drain was more. On 14th, 15th and 16th, the screen off time was 28mins, 1h22min and 58mins respectively. But after i followed the protocols that I have mentioned on my post, the screen off time was considerably reduced (5-8mins max). Check the activity and battery usage bar for the dates 17th-22nd July!!!! Almost the same amount of usage per day and the amount of battery drain is considerably reduced!!!! Hope this helps!!

This is my batt performance after a full DFU Restore to 13.6 and an iTunes backup restore. Just over 2 hrs screen time for approx 180% battery usage. 90% battery health. Any other suggestions? Thx in advance.

Please see the below snapshoot, it's from my phone's Analytic log . The CPU time of the process "itunecloudd" is 154. But it is not reported is biggest process. Also during yesterday- the day log was created- I turned off all network connection. The question is why the itunes cloud service keep running without network ?? . So can I say that the "fix" Peter mentioned in ios 13.6 is just hide all Apple's service from the battery report :D . It's a brilliant fix , Apple.

Something strange now. Probably normal, but I like to know the reason...

When my Xs Max isn't on the charger at night, he almost doesn't consume energy. During the day, no matter I stay at home or I'm at work (at work means driving around connected to the bluetooth handsfree. +/- 8 customers a day, +/- 30 min at their home), the battery drains faster. See the attachment...

What's the difference between night and day in iOS 13.6?

Sunday my iPhone was laying on my desk the whole day and it had the same "battery drain" as today; I didn't touch the phone and it had no blue bars what tells there're apps running.

I've put my phone on charger for an hour or so, pulled off at midnight (was charged to 60%) When I woke up it was on 15%!!! I was shocked my battery died or something. I've seen this when I checked battery usage. :/ The only thing I can think of is maybe live photos run in continuous play in background? (I have sent one yesterday which was on auto Loop/Bounce)... anyone else had similar?

Yes this update is a real heck on battery. My iPad 6th gen usually charges fast enough from less than 10% to full charge. After this update to reach 30% of charge it took an hour almost. I just hate it. It’s really annoying when we need the device.
