iPhone 7 battery drain since iOS 13.x

Have you enabled Siri?

In my case, I have fully disabled Siri and it did became better, but after a few weeks I started to face the same issue again. I've called then Apples Support and they adviced me to factory reset my phone and restore my phone. After doing that, it was fine for a day and suddenly the problem was here again.

Yesterday I did an experiment: I tried not to use my phone for 24 hours. Except for two 10 minutes long phone calls and the messages I've received, I did not use my phone at all. Using more than 50% of battery for a phone, that was almost not used at all, is definitely too much. Something is wrong here. And what's also weird is, that Siri consumed is eating the battery, even if it's completely turned off.

My iPhone 7 was exactly the same, day and a half of light use, down to less than half a day following the 13.3 update. I eventually did a new phone rebuild, including firmware, no 3rd party apps, everything that I was advised to do to save power, and without use, just on standby, I could get between 15 and 17 hours. I was losing 35 to 40% overnight in airplane mode!

I have passed mine to a family member with a battery case fitted, (weighs like a brick), and hoping a patch will be put out, because this problem is all over the internet, though not accepted by Apple it would seem.

I do not believe for a fleeting second the battery has suddenly failed for so many people coincident with the 13 update. I would ignore battery health, it's a poor guestimate which really needs refining.

I now have two phones, one is my old 5s which will still do standby for over two days no problem, same old battery, and is used for Apple functions like interact with my Apple watch and iPad, the other I use generally making calls etc., which goes for 3 days easy, but it's not an iPhone, which is a great pity as I really liked my iPhone 7.

I am having the same problem. My iPhone 7 also gets hot when I use it and does not charge when plugged into a computer. I contacted Apple support and after running a diagnostic said that there is nothing wrong with the phone and that it is adjusting to the new iOS and to give it some more time. I also noticed that the calendar app is using 20-30% of the battery.

Apple replaced the phone under warranty at the beginning of the year and it was fine until the new iOS and watchOS came out.

I have to agree, the very fact that Apple is not accepting battery drain is caused by ios 13 update is still really a big problem, and has lost them many customers from what I have read on the internet, including me, though my 5s is still used with my watch and iPad. Original battery!

I suspect the battery drain may not be reversed, as the problem it must have caused massive wear on batteries in iPhones affected by now. As previously posted, I have factory restored my iPhone several times, including using it as a new phone with no additional apps.

It was a great phone to me prior to this.

I think Apple should half the cost for a battery replacement for all affected phones, and saying for some phones that your battery is covered by warranty and not to worry, could indicate they have a battery problem with quality control.

My used "new" phone is just over two years old, and according to the seller was used for work, yet has 96% capacity still!, which is what I would expect buying an iPhone costing up to £1000.

That's odd.

I would check your battery capacity. Maybe it had a sudden drop.

There are many complaints about battery life with iOS 13. Have you found a solution meanwhile?

That would be me. Apple replaced my iPhone 7 with a refurbished one that had a new battery a few months ago.

Was working fine until the update.
