New iOS 15.2.1 drains battery on iPhone XR:( or it’s just me?

Try a force restart

Force restart an iPhone with Face ID

To force restart iPhone X, iPhone XS, iPhone XR, iPhone 11, iPhone 12, or iPhone 13, do the following:

Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button.

I’ve had the same issue. I called Apple today and I feel it was a waste. They want me to download iTunes and remove the iOS and than back up everything. It’s a mess and I have the 13. I just tired force restarting. I’m charging my phone too 100% and I wanna see what happens. Apple states that currently they don’t have a lot of people calling in the issue. I went from needing to charge my brand new phone every 2 maybe 3 days to every day now. This update was a complete bomb and killed me. Brand new phone 100% battery life. And BAM, an update that’s killing me. Apple please fix this!

Funny you should ask. After updating my XR to 15.2.1 my battery life is greatly improved. I was beginning to think my battery was failing because it would drop below 20% by early afternoon. Since updating that problem has gone away. It’s currently late afternoon here, and my battery is still at 78%, and I’ve ended most days before I charge it overnight above 40%.

Asking Apple to fix anything here on this user to user only forum is like whispering into the wind. You should take the advice they already gave you. If after doing what they suggested it doesn't improve, then schedule an appointment at your Apple Store Genius Bar and let Apple see your phone.

iOS 15.2.1 has not made the battery on either of our iPhone 13 Pro phones deplete faster at all. It's now after 11 PM, and my phone's battery after being removed from it's charger at 8AM this morning is currently 87%. Battery life on my 13 Pro is simply remarkable.

I hate to tell you but yes it has made the battery drain faster. It’s a known fact that it has since Apple ran the diagnostics. They have admitted that the new update does drain the battery faster.

im not asking a user to fix the issue. I’ve asked Apple to fix the issue because I find it to be ridiculous.

Charging every day is a best practice, specifically charge the phone overnight, every night, and enable automatic nightly backups. I’ve had iPhones since the first one in 2007, and every one of those phones needed to be charged every day. If yours didn’t it was an outlier and very unusual or you were a very light user.

I'm not doubting someone may have told you the new iOS drains the battery faster, but I'm telling in no uncertain terms that on my two iPhone 13 Pro, it doesn't drain the battery faster in any way, shape or form. It doesn't drain the battery faster on any iPhone in my office, where everyone also is an iPhone user and is currently updated to iOS 15.2.1.

You are assuming because you and a few others are having an issue, they are universal to all iPhone users. There are millions upon millions of phones running iOS 15.2.1, without battery drain issues. If this was a big and universal issue, this forum, the worlds largest and most visited forum about all things iPhone would have blown up with users complaining. But its not. So you need to determine why you may be having battery drain and not wait for Apple to fix something which isn't universally broken.

First off I’m not assuming anything. Second off I use my phone the same exact way as I have used it since the update. I didn’t do anything different.

I’m telling you this update made it worse. But I’m also using other suggestions before even waiting on Apple. My phone has been off of charge for about an hour and half now and only dropped very little. But the true test will be later today.

let’s see how well things work since I’ve used a suggestion from this thread.

I am a very light user so with a brand new phone and 100% battery life. I find it difficult to believe that the update hasn’t been a issue for others like myself. But again I shouldn’t need to charge every day. Every other day atleast. But we shall see I guess

It is better for the phone to charge it every day; the battery will last longer if you do, AND you will never have an out of date backup for when your phone crashes, is damaged or lost. But you are, of course, free to use your phone any way you want to.

So far the only fix I’ve found was to:

Force restart an iPhone with Face ID

To force restart iPhone X, iPhone XS, iPhone XR, iPhone 11, iPhone 12, or iPhone 13, do the following:

Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button.

so far it’s a temp fix but I still find that the battery does drain even for a light user. I still feel that Apple is needing to fix this issue with a new update and bug fix.

Iphone 15.2 does quickly drain battery life and no, I do not have open apps besides the one I am using and yes, I have cleared my histories. Use to last about 20 hours. Now it is about 9 hours,

I know you are talking about the hardware for XR but I find that it is the 15.0 to 15.2 that besides aggressive and unnecessary changes to iphone functionality, it has significantly made daily battery life shorter and I have restarted it, cleared history and data on all servers and nothing changes the shorter battery life. I have been using iphones for many years with better battery life.

My iPhone Se ( 2nd edition) has suffered appallingly with since the updates. I hardly do anything on it all day ( one phone call,3 texts, 20 minutes radio and a Facebook post today ) and it goes from 100% to 20% in 8 hours. Yesterday I did similar and had to charge it by 3.30pm at work. I have now done a restart. I will chat to Apple and see what they suggest. We only backed it up and rebuilt it a few weeks ago to try and fix something ( wake Hey Siri - no response) and it hasn't. All my older iphones had better battery life. Almost thinking bring back Nokia !

i have iphone 7plus, just got battery replaced @ 1/22 (not because of update drainage - service message); and battery just continues to drain - no rhyme or reason. i have performed the recommendations - and it doesn't matter. am currently looking to buy a samsung phone.
