Battery Drain iOS 13.1.2 on iPhone

***interesting update***

so, my 7 is/has been dealing with the same battery issues you all have shared.

yesterday, after reading through some of the replies I saw one user mention maybe the battery isn't the issue but the battery % indicator.

Thought, what the h3ll he may be right and what do I have to lose.

So I rode my phone down to 1%.

It lasted (with light usage) for a good 2+ hours at that point before finally dying.

I plugged it in for a full recharge overnight and the next day at work, it was drastically improved.

Whereas the day before a 5 minute game of Angry Birds 2 knocked me from 90%->20%...that day it was only down a few percentage points.

Didn't use it as frequently as I had prior to 13.1.2 but I def used it more often than the previous few days where I was afraid of it dying due to massive battery drain.

It made it the whole day before having to go back in the charger.

We'll see how it goes today but just wanted to let you all know...maybe a full drain and recharge helped.

TL;DR: I had been keeping my phone plugged in all day due to the draining issue, guessing some of you might be doing the same. Unplug, let it die and then re-up completely for (hopefully) a noticeable difference.

iOS 13.2 is out. Although it has BIG issue with HomePod, it does seems to improve my iPhone 7 Plus battery issue. I can finally use my phone moderately for 10 hours without charging. It’s worth a try.

Time to replace your battery, it seems.

**REPORT**

Just wanted to up date you on my experiment. I had my iPhone with me for at least 8 hours without being able to charge, but I hardly used it. Some when I got back to base ai opened it and found the following.

After opening phone it showed 22% and promptly started counting down battery % until it got to 1% in about 5 minutes. I got reminders to switch to low power mode at 20% and at 10%. 

It then stopped at 1% and did nothing. I was hoping it would switch off but it just stayed on 1% for at least 15 minutes. Then I switched phone off and back on again and the battery % jumped back up to 22%.  So I started using it randomly changed setting to switch screen off after 5 minutes so I can see what happens. It’s normally set to switch off after 30 seconds. 

As I’m typing this in my notes battery is draining albeit slightly slower compared to before. Now at 3% after receiving warnings again at 20% and 10%. Left it to see if it would switch off at 1%? 

Time check at 21.30 and battery showing 1%. 

Time check at 21.40 and battery still showing 1%

Time check at 21.50 and battery still showing 1%, started playing music , increased screen brightness to full and kept phone on at all times, to try and force a switch off, but it isn’t. In days gone past 1% usually means an automatic switch off after a warning. No more warnings either.

Time check at 21.53, phone finally switched off without any warning.

Charger plugged in and within 5 seconds it switched itself back on.

Left it to charge overnight and next morning, 100%.

Had some low activity during the day from around 9am until 6pm, it was never on charge and amazingly it still says 60%. This definitely would have been worse before I totally drained the charge in the battery and started again. It doesn’t appear to be heating up either, so maybe this is a partial solution to the issue. It’s worth a try if you’re currently struggling. I will continue to monitor over the coming days and unless there’s an update in the next 5 days, I will be contacting Apple when I’m back in the U.K. hope this helps.

After running 13.2.2 and now 13.2.3 for a few days things seem back to normal. iOS 13 still seems heavier on the battery than 12, but without solid data it's just a hunch. In any case I don't have to charge 3 times a day like pre 13.2.2. That was weird.

How we can let Apple know about the iPhone7 battery drain problem? Battery is empty in 10 hours without usage.

You can contact Apple here:

Genius Bar Reservation and Apple Support Options - Apple

They can do diagnostics remotely.

Hello again. Ok, another scan was run on my phone. The scan showed

that the battery is not good so I am currently getting the battery

replaced. I still think maybe IOS 13 is messing with it but at least I

will have a new battery. Have another year with the phone so it better

work. I also asked if having it on the charger most of the time could

affect and they said no. So time will tell. Will see what happens and

will post again if necessary to update you all

I have spoken with Apple Support just now, we ran a diagnostic on my 6S and he confirmed there's no issue with the battery, the health is perfect. Well it should be it is only 1 year old (through the apple replacement program) . He then recommended to switch off 'background app refresh'. This I had done previously with 13.1, but when 13.1.2 came out or was it 13.1.3, oh flip I'm losing count, anyway which ever one it was and the battery was behaving slightly better, I switched background app refresh back on.

So he then suggested I should monitor what happens for a few days when app refresh is off, then if it performs better start switching some apps back on, one by one to see if it is a specific app that is causing it?!

As I am talking to him (and app refresh is off) the battery dropped from 92% to 81% , then I had to check train times on an app (UK railway app) because he suggested I can also take the phone into a store and they will run a deeper diagnostic on the phone, it dropped from 81% to 72% literally within seconds. When I relayed that to him, he then said YES this shouldn't be happening.

He concluded seeing as the battery health is fine, it has to be a software issue. He's half saying it has to be an app, but the only difference between yesterday and today is iOS 13.2, so it HAS to be Apple's software.

To be continued...

So I’m in the Genius Bar in Birmingham UK and they confirm that iOS 13 has been an issue. All in-depth diagnostics done again and confirmed that no unusual usage and the battery drain is too fast for very little usage on my phone, at least we’re not all imagining it. They recommend a complete wipe and reinstall. The recommendation is to use the phone for a few days without restoring from backup and see how it performs. So my phone has been wiped and I will use the phone in a raw state to see how it performs. A call back from Apple has been arranged for this coming Sunday 10 November so I will give you a further report after that.

The answer to my question, ‘what if this action doesn’t resolve it? We will have to escalate to engineering, but likely the outcome will be to wait until the next iOS update’. 🙁

To confirm, my device is S6 with 13.2 installed and a battery that’s 11 months old with a 98% maximum capacity on battery health.

**WARNING: Please do a backup before you wipe your phone. **

Success, Michael ツ

Call support, the issue is so new that release engineering hasn't admitted to a problem- You must open support tickets and make sure they contact release engineering.

Call support so they know they have the problem sooner, they aren't looking at these threads

Initiate a support ticket, they need to know how many of us are experiencing problems after 13.1.2- I called today and they said release engineering didn’t have any open issues- report it thru the chat- they aren’t looking in this community!

@pashaaa

when I spoke to Apple support they told me not enough people are reporting the issue as they haven’t got it recorded as a major issue. Please do call them and if necessary if there is a store close to you go and see the Genius Bar too so they do a full diagnostic. Wish you success.

Battery drain on Iphone 7 Plus after IOS update 13.1.2

My battery lasted 6 hours when the day before the update it went all day and was still at 30 percent.

I check my battery usage and the Notes application said it used 54% of the battery usage. Is the notes app why the battery is draining so quickly? Is it upgrading the notes on my phone? Not sure why it would take that long as i store my notes in Icloud and don’t have that many notes to begin with. Maybe a problem with notes apple notes application on this version of IOS.
