iOS 12.1.4 battery drain

Every update since I can remember on Apple Android and Playbook forums, users have blamed the latest update for battery drain. It’s some sort of tradition.

If nobody wants to post a screen shot of battery usage from settings there is little anyone can advise except wait 2 days for the search indexing to finish and if you still believe your device has a problem either restore from backup or restore as new and the fresh copy of iOS will be fine.

Yup, everyone wants to complain about the latest update. Very rarely are they willing to do any troubleshooting.

Did you post a screenshot of the battery stats? No. How helpful was that to us?

12.1.4 is not a bad update, but updates can be installed badly (not your fault but it happens if uou have a legacy of stuff in there).

Restore as new and come back here if it works no better.

A bad update on 3 devices? Sure that would be so unlucky, if I post my battery stats how will that help you?

Like I say, I’m reasonably bright and keep my devices in good order, I’d prefer not to restore as new on 3 devices just yet, hopefully enough reports will lead Apple to scrutinise their update. After all it wouldn’t be the first time they’ve had to admit their update was the cause of poor battery performance would it? And now I need to plug in as my 2 month old iPhoneX has just 13% battery left from being fully charged at 6 hours ago and all I’ve used it for today is 2 short phone calls and posting here

Today you had 3 hours of screen activity and have 59% remaining.

I don’t see anything drastically wrong

Did you upgrade on Tuesday?

Wednesday had a poor screen time to battery ratio . If you tap on Weds bar does anything show up obvious?

It was on charge while I was using it today

i updated Monday evening, nothing out of the ordinary on Tuesday, Wednesday or any other day since other than it’s fully charged in the morning, hardly used all day and dead as a dodo by teatime, most of the usage is while it’s plugged in. That screenshot is my iPad Pro, my iPhone X is showing a similar pattern and I’m also having to top up the charge during the day. I haven’t updated my iPad Air and that’s not having battery issues

I’m am by no means a Apple expert or trying to sarcastic but the facts are

we have different types and age iPhones from all over the country with varying degrees of usage that are having dramatic battery drain . And the only thing they all have in common is that they all have updated to iOS 12.1.4 . Also buggy updates could have a correlation between reduced iPhone prices and the causality of lower sales volume .🤔🤔🤔🤔

Ok. Sorry I poked you gently in the ribs but there is a powerful anslysis tool there that I wanted you and others to at least look at.

Charging during part of the day will mask any good analysis unfortunately.

Screen shot each day at bedtime for a while, not the 10 day summary. Thats for you to analyse not me!

I guessed you may have updated Mon/Tues because it showed 2-3 days of poor performance as the Spotlight index rebuilds.

Friday is therefore better on the face of it without knowing if any of it was powered up.

Good luck with it.

For a model by model empirical battery test.

The conclusion was some models were slightly improved, particularly iphone 8 and some were slightly down.

overall there was little or no improvement in battery life.

it did *not* conclude any drastic downturn in battery usage after update to 12.1.4

Re

“nothing out of the ordinary on Tuesday, Wednesday or any other day since other than it’s fully charged in the morning, hardly used all day and dead as a dodo by teatime,”

Take a look at Tuesday graph. It shows 6 hours screen on activity which seems to contradict the above statement. Just noticed it.

I too updated to latest iOS and am experiencing RADICAL battery drain. In the last 1/2 hr my battery has dropped 10% - with all apps closed, signed out of all accounts (Facebook, Instagram, etc), and doing nothing with the phone! All was good until the latest update was installed...

Give up trying to catch me out, 6 hours was evening and early hours (I’m a crap sleeper) the 6 hours was while plugged in. In the morning 100% during the day left on the bedside table not plugged in while I am at work, by the time I get home 8 hours later having not used it was dead as a dodo

Just imagine ALL the fun we’re going to have if the ‘fix’ is to turn OFF Wi-Fi?

If it gets to that, I might as well go back to ‘pen and paper/pencil’ (not the Apple pencil)

as this is ridiculous in trying to convince Apple that there is something wrong with the update!

Hey Apple! Did you ever stop to ‘think’ that the battery ‘problem’ might NOT be related to ANY apps

and that is WHY NOTHING shows up in the ‘battery usage’ area

since they aren’t measuring ‘battery usage’ by JUST the OS/kernel itself, so OBVIOUSLY nothing shows as excessive there!

Catch you out? Really? Just trying to help you and read the data you provided. Trying to work out why my phone and ipads go like a rocket on 12.1.4 and batteries last all day where yours dont. The only differences can be apps and setup.

When you post that what you see in my stats is contradicting my own statements whithout having full knowledge of the circumstances, is that you being helpful or trying to make me look a fool?

I’m our if here, I don’t have the time or energy to defend myself against buffoons who won’t do anything other than contradict for the sake of contradicting

to the rest of you having the same issues that I’m having, good luck. I’m taking my two month old iPhone X back to Apple with a battery fault

Having the same issue and I am using an iPad Air. Noticed after the download of the update iOS 12.1.4 the time frame has been cut in half for how much use I can get before needing to re charge. I am doing the very same things with my iPad and yet I am seeing the battery drain from 100% to 70% in 90 minutes compared to 2 1/2 hrs.

also, seeing serious battery drain from 30% to 10% where it will go from say 22% to 19% in a few minutes and then drop from 19% to 10% within 5 minutes.

there is certainly something in these updates going back to iOS 10 that is messing with the battery life. And good luck getting Apple to respond when you contact them on their website, especially the Bug Report - filed one with them early this week.
