Battery Drain iOS 13.1.2 on iPhone

There is no doubt at all that the latest update is messing up the phones. Up to yesterday evening, before I HAD to update my iPhone 7 Plus, my battery used lasted (on average) approximately a day and a half. Since the new "update" my phone is on 26% after 4 hours powered on with almost NO USAGE whatsoever.

Besides the Calendar bug (that has reappeared after this "update"), I've not had any issues at all with the phone.

If Apple don't resolve these issues in the next few days, I will have no alternative other than to purchase a new phone - and it won't be an iPhone.

Hi again,

Another update with my IPhone 8 and the IOS 13 battery problem. I met with my son on Saturday, has Iphone 8 also, got them at the same time. Says he does not have any problems with his. However mine continues to drain rapidly. We checked the battery health and it says that I have 95% maximum capacity. It also says my battery's health is significantly degraded. So tomorrow I am heading to the apple store and have them look my phone over and see what they have to say about this IOS 13 and what it is doing to our phones. Also I noticed which may or may not be related, that I have my notification (sound) for text messages set at 5 times. Use to use 3 and worked well, then started getting only one notification (sound) when I installed IOS 13. Moved it to 5 and still only get one. So will ask about that too. I will post what I find out

its not about your iPhone being old or any Apple tricks. A friend is experiencing the same problem on the new iPhone 11. We did some tests together only to find that the battery drop to 30% very quickly. We did everything we could find useful but nothing solved it. I regret upgrading to iOS13.1.2

While that is true Apple will probably release a fix soon, my phone is practically unusable. Besides, they have had similar problems at least twice (see other threads in 2016 and 2018). You would think they would have some experience avoiding this particular issue or at least do some test prior to release.

There is no question in my mind that Apple is either ignoring this major problem or secretly trying to find a fix. My problems are similar to those being described -- and I've spent an hour on the phone with Apple, then two hours with the "geniuses" in the busiest Apple store in the world at Century City in LA. I have a IPhone6s with a 11-month old battery. What's the story Apple???

Another update from me. Updated to 13.2. Battery seems to be decreasing a little slower but not much. Had to replace the battery in my IPhone 8 a couple weeks ago. Had 95% charging power but still had to replace it. I think Apple should reimburse us for having to replace the battery because of it being their fault. I was doing great until IOS 13 came out. Never had to replace a battery in any of my Iphones, going back to the Iphone 4. Now this within 12 months. Pathetic.

Update Nov 10

after my follow up call with support, which was scheduled after my visit to the Genius Bar in Birmingham UK they escalated my case to senior support. So after being told to run my phone without restoring for a few days, now I’ve been told to restore from back-up and then run for a few days. After that on Wednesday Nov 13 they will take logs from my phone and submit to engineering. They are also logging this as a complaint. After 3 calls and one visit to a store they are confirming the complaint. If you have the time and inclination please continue the process of reporting it, the more complaints can be lodged the better. Success. ツ

Is your battery also draining when your device is plugged into a wall charger? I have an iPad Pro and, prior to all the iOS 13 updates, I could plug it into a charger and use it without the battery draining at all—-in fact, it would charge. But now, I can have it start on 89% when plugged in, then steadily drop to 50%, fluctuate as much as 5%, then drop again. But if I don’t use it, it charges, though it takes all night. I can’t seem to find any viable solutions to this problem. I’ve followed all the battery-saving suggestions, and even did a reset (but not to factory specs), but no improvement. Frustrating.

Same here :-(

I used to use my phone all day without care – and now suddenly it's drained after only 2-3 hours.

I'm getting back the charging paranoia I had with iPhone 4S

I have all the new updates for my 7. It’s made no difference. Battery still drains when the phone gets hot.

I have the same issue.

My iPhone 7 Plus on iOS 12 used to last me the whole day.

After iOS 13.1.2, my phone's battery level would drop to 35% at 2:00pm with close to no activity.

It would be great if someone can figure this one out.

I have the same problem on my IPhone 8. From 100% to 70% does not seem so bad but from 70% to 30% only takes about 45 minutes when I am texting with someone. I have turned off almost all notifications and still no luck. Hope it is a bug they will fix soon.

I disagree I have iPhone 6s battery just replaced 6-months ago at genius .It still has a battery life of 99% and lasted all day no problem .Now with iOS 13.1.2 the battery drains like a big v-8 engine while you watch the fuel gauge go down it is terrible and unacceptable .As far as I'm concerned this is a planned by Apple to force us to upgrade .I don't know about you but I had enough . I am now disabled and just bought this phone in mint condition and have no money to replace .Very unhappy with greedy big companies .

I see the comments and in my opinion do not install 13.1.2. It is messing with a couple apps of mine too besides the battery. What I don't know is if the battery gauge is accurate or not. It is possible the battery is fine and the gauge is messed up or visa versa. Whatever it is hope Apple sends out another update and fixes it.

I use iPhone SE and had no problem with batter till upgrade to 13.1.2 . Prior my battery was holding like 24-29 hrs with standard use of phone . Now a 12 hours later my battery dropped from 75 to 16 % within 3 hours ( no video , no games ) . And % are dropping from 18% to 11% within 5 minutes . I red all above and I do come to think that if release of new IOS harms usability of older phone that means something about how company treat client. Which is very low in this case ! If that is policy of coompany my next phone will be most likely not-iPhone .
