the same problem happened to me after I updated the IOS to 14.2.2,
I was advised to wait for 14.5 because it seems to be a software issue because if it was the battery, it wouldn't last like 10 hours on 1%
I hope that to be the case because I'm very worried,
I have only access to Dubai and Turkey, which only Dubai has authorized providers, and the US AppStore online support told me there's no guarantee for your iPhone 11por to stay waterproof after changing the battery or being opened by those authorized providers, and due to corona limitation, it's not easy to travel to Europe or US, despite the cost !!
So please anyone help if you know anything regarding this.
I'm very disappointed because I bought this iPhone 11pro and AirPods pro one year ago, and my AirPods pro didn't work after 11 days,
I replaced them in Dubai under the warranty and the new one recently has a mic problem and they said the 90 days is over.
so I have paid lots of money and now I have an iPhone who stuck at 1% and an AirPods pro which doesn't work
if anyone from apple read this, please kindly advise or help.
