11.4 update battery drain

I’m calling BS to the Apple response. The old replace the battery, it’s your apps, gps, indexing, etc. is not the problem.

It’s 11.4 software upgrade!

My phone goes nearly flat from 100 % overnight with everything closed, no mail pull, etc. just sitting. I’ve heard the standard answers given every time there’s a problem with an apple phone. I’ve had a few by the way.

What needs to happen is you need to say sorry Mr. Customer, we will rush a patch thru on this issue right away.

No cheers, just bad service from Apple.

Hey, generdude.

I see that the battery life of your iPhone 6s has dropped, and I'm happy to help.

iPhone Battery and Performance -- This article provides information about the battery, how to maximize the performance, and introduces Battery Health (Beta) which can also help.

iPhone Service Pricing -- If your battery needs to be replaced, this is the pricing for the United States. Just scroll down to the heading "Battery service - United States". If you're in a different region/country, scroll to the bottom of this article, click the country listed in the lower-right corner, then select yours.

Take care!

I had the same problem and found the solution with the help of Mike Wuerthele at Apple Insider which worked perfectly for me. You'll need to do a clean install of the system.
Do these steps:
1) Back up your phone
2) Turn off Find My iPhone
3) Restore to factory settings and do a clean install of your system
4) Restore your iPhone with your back up

This takes a while - a couple hours...

I am facing similar issue, updates ios to 11.4 last week. Before going to sleepni charged it to 100%. When i wake up its 30%, i use it for 5 mins its 15%. My battery 2 and half years old but it was not this bad before update

Likewise, I have the same issue with two of my iPhone 6s Plus while the battery of my iPhone 7 Plus only drains 2%. I took one of phone to Apple Store, the Technician told me that there is no thing wrong with phone battery. And he ran the Restore and Update procedure using the computer to ensure that the update is complete and proper. However, the problem persist. The phone was fully charged around 10 o'clock before I went to bed, and it shows 19% left in the morning.

I'm experiencing a similar issue. I wasn't having any issues with battery life on my iPhone7. Then I updated to 11.4 a couple days ago and now my phone has died on my twice. I have not made any other changes to apps or usage. I hope there is an update that will fix the battery drain.

Well most that have owned apple products know the drill. Turn off, hard reset, turn off mail pull, gps, etc etc.

doesnt fix an actual problem. Im just fed up with the apple baloney. Just fix the problem. Mine has dropped 10 batt. points in 20 minutes. Ridiculous.

It’s the denial of issues that aggravates me. Year after year, same thing. The list of scripted answers given are the same. Spend lots of time blaming the customer, it’s your battery, your apps, restore the phone, stand on your head in the corner while holding one ear, on and on, then eventually fix it.

UPDATE: I previously posted that a clean install of the system fixed this problem. It fixed it for one night where the battery decreased from 100% to 97%.

Last night I went to bed with a 100% charge on the battery and woke up 8 hours later with 1% so this issue is beyond doing a clean install of the system. For clarity, this is an iPhone 6s which is 8 months old and battery health at 97%.

My iPhone 7plus and iPad Air II are functioning normally after the update to 11.4

Turn off your Wi-Fi. Definetly helped me.

Lost 60% overnight on Iphone 6s, next day i charged it to 100% and decided to turn off my wifi. I woke up with 100%. Turned on wifi and did nothing on my phone - lost 15% for an hour...

I’ll try it again. It didn’t work in my 6 (not S) the one time I tried it. Are you saying overnight!

Mine usually charges at night. I charged mine then set it on the nightstand overnight. Everything off. Went from 100 to 33 in 7 hours.

I’ll try one more time.

I totally agree with you. I always charge both my iPad Air 2 and iPhone se every night. My iPad is the only device I upgraded to the 11.4. Yesterday I got up to a fully charged iPad, I assumed, I really didn’t look at the charge status. When I got home from work 8 hours later my battery was at 7%. I thought perhaps one of the prongs to the charger may have been down and not fully engaged in my outlet, so last night I double check to be sure they were both engaged. I check my charge status and it indeed was at 100%. Today when I got home I had a dead iPad and had to immediately hook it up and charge while using the device.

Apple needs to step up their game and fix the battery drain issue. I know the tricks about turning off battery draining apps and services, so it’s time another ‘bug fix’ is initiated.
