IOS 13.1.3 battery drain

I have two 6S phones and they are draining at around 1% per minute after this update! But this only happens at home where there is poor signal reception. In my office where I have a strong signal it is normal. So it seems to be linked to the phone struggling to reach a cell tower... I though Apple solved this issue 10 years ago!

I would have to disagree that having a bad app that is doing this isn't the problem for everyone.

As I stated I have a newer (less than a year old) XS and had no issues with iOS12; in fact it was amazing. I still had no issues after iOS 13 and then the subsequent patches but the latest update iOS 13.1.3 has effected my battery life. I have not downloaded any new apps and have no heavy use. I have turned off the Optimized Battery Charging as another poster suggested. I will see if this helps any.

I agree with Oscar-24!!!!

my phone was fine and I put off updating fto

13.1.2 to iOS 13.1.3 until my phone forced me to. Just after I did something flashed across my screen about my battery. It was so fast I have no idea what it said. Something about the battery life and charging it over night and 80%. During the day I’m at work and not on my phone so it really should not drain much. And it didn’t until iOS 13.1.3. So there’s definitely a sw issue

now apple needs a fix to fix 13.1.3😡

Guys , this could help- Follow this video and all its steps even the last one, to do a hard reset on your phone...(restart)

Also I’m keeping it on low power mode for now until the update arrives.

It may not work but it’s worth the try!

Why did you link to a video, rather than just state the steps? Doing so would have saved users several minutes. Of course, you might not get a click credit for the video.

It seems a bit more reasonable today, but you shouldn't expect the indicator to be fixed just because you calibrated your phone. If it is buggy, it will continue to give wrong readings regardless of battery level and calibration. My suggestion is to check how long your phone is lasting before it dies and check if this is any worse than before. You might panic and start charging it when it shows 3% when in fact it is at 10% or 15% and still has more hours of life in it. But 13 is definitely an unlucky number for Apple!

Just for reference if anyone needs it. I have tried everything. Erasing and starting over not from my icloud so that's it's legit a clean start. DFU restore (google it, i had never hear of it), optimized the battery twice. Nothing has worked. When I originally went to the apple store to purchase a new battery, he did an erase but put my icloud back on and said it should be good because the battery says 90% efficiency. But he also said to do the erase all and start from scratch if that didn't help. (Since it didn't help that's what I did, plus all the other stuff I mentioned). He did say that if that didn't do it then sometimes the efficiency read out doesn't read correctly so it could be a bad battery. I had planned to go back and actually have the battery replaced this time, but then I started to doubt if a new battery would even help since the SE is so old. In the end, I decided to let go of the SE and purchase a new phone. I was hoping it was just an SE problem since it's one of the oldest left but seeing the iPhone 7 mentioned worries me a bit. Anyway, if anyone ends up getting their battery replaced, I'd be curious to know if that fixed it.

I have this problem too. Same usage but since updating to the newest iOS my phone battery is dying even if I am not touching my phone. Goes from 100% to 20% in an hour or two...

Funny thing is... if I do a hard reset the battery life shows as way higher (70-80%) but then drops down again super quick. Not sure if it'll die or not but something is wrong with the software.

I am having the same problem. Genius bar employees couldn't figure it. They exchanged it out for a new phone TWICE!. Activated it as a NEW phone and 2 days later, Apple Photos showing consumption of 15 hours in background up to 82% battery usage. The back of the phone is uncomfortably hot. This is frustrating. Anyone got a solution(s)?

The drain is not real, it is just the indicator. You can immediately stop the drain by shutting down all running apps. When you log back in the power indicator will stop draining until the real power state is reached.

i have tried reloading all apps but have not been able to identify what kicks it off. Happens a good few times a day. At least it is a sort of workaround.

I have an iphone10 and never had an issue with my battery until 13.1.3. What is weird is I now will pick up the phone after not touching it for 4hours and it will not turn on because how low the battery is. That never happened before

My iPhone was fine for a few days after its initial battery drain, then yesterday at 9 am it felt hot and was draining away 10% over a few minutes. Turned it off and left it to cool for 30 mins, its been ok since - weird.

now that i think about it sort of makes sense; the optimised battery charging is learning your charging behaviour to optimise charging capabilities. So maybe just guessing here, it works in the background to learn how one uses/ drains their battery so that they can predict when charging would take place and with what conditions. And is battery intensive at the beginning until it learns those charging habits.
