Battery drain since iOS 15.6 is ridiculous

My battery life has improved greatly after updating to 15.6. After following the best practice of charging overnight, every night with optimized charging enabled, before updating I would be at 20-30% by the end of the day. Now it’s around 50%. So rather than just complaining go to Settings/Battery and check what is using all that energy. Battery energy doesn’t just evaporate; SOMETHING is using it, and that something is always an app or apps.

This is NOT an end user problem. I updated my iPad this morning and after the update, I went to a meeting. During the meeting (1 hour) my battery went from 84% to 2%. This has NEVER happened before. Something is definitely wrong with this update. Unlike others reporting here, Battery usage shows NO application eating up the battery. I'm hoping there is some sort of background cleanup or other going on and that this is not a long lived problem. I did not have this problem on my iphone after I upgraded.

It isn’t an end user problem, but it IS an app problem. The phone uses almost no energy on its own; if there were absolutely no apps running on it and it was locked the battery would last almost a week. Other than periodically registering with the cellular network all energy use is by apps that are doing background updates, iCloud or other cloud function syncing or processing notifications, email, text downloads, etc. So you need to fix it by identifying the apps that are using that energy. A good first step is to restart the phone; this kills all apps on the phone and forces them to restart, so any that are “stuck” will start fresh.

ios 15.6 drain alot of battery like ios 15.5 or other previous versions on my 12 pro max. may be its a second last update of ios 15 but they didn't fix battery drain issue on 12 series or on older device. they take whole year to fix issues and here it comes battery drain, they only focus on latest new models only. apples optimisation in battery life worst.

Dave ~ What model iPad is it? (So we can know how old the battery is.)

How do you explain that both Lawrence and I are experiencing better battery life with iOS 15.6.? Are we just better at using our phones?

which model you using? and how do you explain this that since ios 15 releases my 12 pro max starts battery drain and ios 15.5 and ios 15.6 drains battery much i tried everything restarts, reset all settings, clean install and after that and for your info. battery is good in shape i go to genius bar and they checked so what do you say?

I think you missed my point. If the problem were with the update, everyone (or huge numbers of people at least) would be having a problem. And, not only is that not what's happening, some people are seeing improved battery life. As long as you keep insisting that the problem is with the update, you're not going to get anywhere with resolving the issue.

I’ve already explained. If you would prefer to just complain rather than troubleshoot the problem that’s your choice, but the troubleshooting would probably take less time than you’ve spent composing posts. Roughly 500 million iPhones were eligible for this release; if even a tiny percentage of them has the issue you are seeing there would be tens of thousands of posts about it. So the logical conclusion is that it’s a problem specific to your phone, and needs to be solved on your phone. It probably doesn’t even have the same cause as others who have reported a similar issue.

Exactly why i have posters remorse every time I put something on here or ask for help from Apple. Instead of berating customers, why don’t you do a Google search and you’ll see there already ARE thousands of posts and even some news articles about people seeing this problem.

So over the arrogance of Apple.

You're not the customer of anyone participating in this thread. And disagreeing with your assessment of the cause of the problem is not "berating" you.

Please watch iApplebytes 15.6 video and see the results yourself. I baby my Xs Max and now just over two and a half years old. I followed 40-80% charging practice since day one and battery health is at 96% right now after upgrading to 15.6. (I lost further 2% upgrading from 15.5 in a matter of two months. ??) I stayed on 14.8.1 until 15.5 was released. I’m not a heavy user and I know my Xs max doesn’t have the best battery life comparing to latest pro maxes but I’ve been using the same apps for years few hours in the evenings while my iPad is charging. I always keep all background apps off at all times including mail fetch and find my. I've noticed on 15.5 my cellular signal constantly changing between one to 4-5 bars, this is all day and night. And still behaving the same on 15.6 perhaps because there was no new modem update. I have nothing to say about the performance of 15.5 or the .6 and no battery drain over night but soon as start using my phone, battery counts down like a timer clock, 2% every 15min or so and Im not talking about indexing for few days because of upgrading or so, issue still continues a month later (on 15.5) and now 15.6 and this is really noticeable. My brand new iPad Air was on 15.3 when I purchased it and since 15.5, behaves exactly the same so it’s not only my iPhone. You also yourself don’t say what phone you have, perhaps the newest devices are not much effected because of their battery capabilities. I don’t know but please watch some latest performance comparison videos yourself and you can see what I’m trying to say here. With every new update, it seems to ruin my devices battery life. You may agree or not.

they never admit these facts because they only tell same lines and same troubleshoot, they think we didn't try anything like that but I don't blame them they just told us what apple told them , when company itself not focusing on better battery life on one year old phones, so its a waste of time here. they never believe, at the time of writting this comment i lost 2 percent battery . acc. to apple its normal after all methods i applied... well done apple. apple is waste of money .sorry but thats the truth.

The battery on my phone 12 Pro max, is running down super fast too, i thought its my phone battery issue then I realized i just updated to ios 15.6 and found that this caused this battey issue, Apple tech kindly do something about it. Hope you release the fix so soon.

As a royal Apple user for years, I believe we should have a choice to roll back to older versions of IOS, such as 14.3 when my iPhone Xs Max used to last almost two days of battery, not few hours. I really don’t need all these fancy features. I just want my phone last through the day as it used to. Now I’m stuck in this awful software with no turning back and I really don’t believe IOS 16 will be any better, because my phone is so old now with 96% (original) battery health?? Give me a choice to roll back please. At least one stable version of older IOS.
