Ios 15.1 battery drain

For example, Settings then Battery switch off the setting for Lower Battery, by changing that setting cost me 5% battery. In short all the new fx of 15.x I needed to switch off in Settings, for me 15.x is not ready.

Do not upgrade to iOS 15.1, I have made that mistake.

Brand new iPhone 13 and now I have to keep my charger in my pocket because the battery drain is bad?

this is outrageous. A software fix must be available sooner than later.

I installed IOS 15.1 only a couple of days ago and, since the update, just like every else, the battery drains extremely fast. I could go 2-3 days on one charge before. Now, the battery goes down from 100% to 60% within 4 hours. Hope a fix is coming very soon. Apple has been aware of this issue for more than 2 weeks!

Yes I’m having the same problem. I’ve turned off phone and restarted as apple suggests also turned off background app updates but makes no difference. Nothing is running in the background. Hoping they come up with a fix soon !

SE20 running iOS 15.1 with same issue. Battery down to 15% after a full charge. Last two updates seems to be this issue persisting. It’s seems obvious from reading the forum here that the update is affecting iPhones battery.

Absolutely echo that. My latest news is that engineering requested usage data from my phone 2 weeks ago and I still haven't heard anything back, so will be following up with them today. They did say not to install 15.1.1 as they maye require further log files which leads me to suspect that the 15.1.1 release has no specific fix to the battery drain My general sceptical nature is leading me to suspect that this isn't an issue Apple wants to own up to and that they're just prolonging the ongoing support ticket that I raised until 15.2 is released.

As a general comment (this is not a direct reponse to you or anyone else in the forum) - any advise I've seen either here or through other forums or even from Apple themselves is basically irrevelent advice. My sentiment is that my phone is there to work for me as I wish it to operate. After an upgrade, if I now have to alter my own life to suit my phone, that then defies the purpose of the phone as I now would work for it and not the other way round. I don't want to switch off background app refresh, I don't want to switch off notifications, I don't want to constantly reset network settings or limit the amount of time I spend using Safari. any advise that Apple or anyone else gives that makes me feel i have to change my life to suit the phone, is basically not advice at all. I've said this before in a previous post, but I can't use my device as I want to use it (and indeed have been able to use it up until 15.1), then the device is no longer fit for purpose. It's like having to hold a TV antenna in a particular spot to get a signal - It's just not what anyone would want to do.

Apple simply won't admit to there being a problem because they don't want to open themselves up to any lawsuit by saying there is a mass problem. I can only hope that 15.2 solves the problem because if it doesn't,then the legal route is the one I'd be taking. Consumer law provides a lot of protection for people and I'm giving Apple the benefit of the doubt to have this fixed by 15.2. I take great care in looking after my battery health (still 99% after 13 months of use) and if this additional constant recharging is now damaging that further then I would say that's open to legal recourse. Just my 2cs. I'll keep everyone posted in case Apple engineering get back to me.

I updated via my device Settings > General > Software Update while on Wi-Fi and both devices connected to power.

• Note: The iPad completed the update first. The iPhone took a little longer when I was using a wireless charger. But when I connected to power, it finished in less than 5 min.

Hope this helps!

You should never be scared to update/complete software updates. They are created to improve your device functionality.

Give it a chance! :) Sorry you’ve been having some issues with it.

Do you wirelessly connect, sync, or backup to a Macintosh? if so, what version of Mac OS is on that Mac? Thanks!

@k_p95 Thanks. but I am asking the above question for a reason, for an answer that might help others including me.

If you didn't understand, let me ask this another way - did you plug your iPhone into a Mac, have to click on "trust this computer", and then enter your iPhone PIN? IF NO, then that is all, thanks.

IF yes, you HAVE "trusted" the computer, then when you click on the iPhone's name in the side bar in Finder do you see that the Mac is set to "SHOW THIS IPAD WHEN ON WIFI"? IF NO, then that may be why you have not been affected by the battery drain. IF YES, then I might be wrong about the cause of my own battery drain. Thanks.

It took a couple of days after the update, but it seems the battery life span increased again and got settled. My battery is holding up again how it was before the update.

just installed 15.2 IOS and hopefully it stays as stable as it is right now. Because I’m fully pressing the battery on usage right now and so far no mayor drainage occurred.

Using iphone 11. There is battery drain in ios 15.2. And after updating, my iPhone's battery capacity which was 99% previously before update fell to 98% after updating to ios 15.2. When I was on ios 14.4 the phone battery capacity was 100. When i updated to ios 15.1 it fell to 99% and now after installing 15.2 it fell to 98%. It seems with every update the battery capacity gets reduced. I know Lithium ion batteries degrade with time. But reduced battery capacity with every ios update is something I not happy with. It’s too early to say if ios 15.2 actually drains battery because it takes upto a week to stabilize. And after ios 15.2 I will probably not update my iphone again until i buy my next iphone. Should have stayed with the iOS version with which my phone was shipped.

Yes, I have reported it to Apple. I was hoping that 15.2 would solve this issue, but it didn't. Before 15.1 I used to have 24+ hours of normal usage (ie. normal for me), with 15.1 and 15.2 I charge my phone twice a day because I get 12-13 hours of usage. Battery capacity is still 98%.

And yes, I tried resetting my phone, I tried resetting my Network Settings, I tried everything. All in all: ridiculous battery drain. One very disappointed and annoyed old iPhone user.

Yes, it kills my phone 5-6 hours after the full recharge, even if it's not being used at all.

You can try searching on this forum, you will see a bunch of complaints already. 15.1 worked fine for me, by the way, but 15.2 just made the phone basically unusable.

Siobhán ~ The iPhone 7 itself is not old, but its original battery will have inevitably weakened over time and cause the symptoms you describe. What's the % value here?...

Settings > Battery > Battery Health > Maximum Capacity

OK I did the test, charged to 100%, turned phone off all night, turned on this morning battery was at 96%. within 15 min. the battery dropped to 86%. Put the phone in standby and after 1hr. without using it it's down to 38%. I have changed nothing on the phone, gone through privacy and everything is set to while using app.
