Question: iOS 11.4 battery drain

My iPhone 6 was working perfectly fine until I updated to iOS 11.4 and ever since I did that my battery is draining rapidly even without me using it at all. I used to go a full day without charging it now it may last half a day. I am just wondering if something got turned on with this new update that I have to turn off to save battery life. It is just weird I have not done anything other than update the iOS and now this happening. Any help would be greatly appreciated.

I have the same issue with my 6S+. It was fine before the update. And my battery health is at 90% yet I just watched my battery % drop from 50% to 20% in a matter of minutes while not using it. I’ve looked through all the settings and can’t see anything I’ve previously had turned off turn back on with this new update in regards to saving battery life. Whatever it is that’s causing it they need to fix it ASAP

My iphone 6s has the same issue after updated to ios 11.4. I charged it up to 100%, rebooted it then let it stand by for 4 hours, the battery indicator dropped to 40%. It has been 3 days since I updated to ios 11.4 and this issue happened every day. Also it seems the battery drained fast when my iphone connected to wifi. When there was no wifi connection, the battery draining seems slower or normal.

Iphone 6s (BH: 95%) and Ipad Mini 4 (BH:96%)

Both units show since days the same annoying battery drain (60% overnight). Also a clean install with 11.4 on the phone didn't improve the situation. Yesterday I downgraded to 11.3.1 on the iPhone and everything's back to normal again. Overnight (~ 7h) the energy loss was only 1%. I'll keep the Ipad running for 2 more days to verify the behaviour.

Greetings,


I see that the battery life of your iPhone 6 seems to have shortened, 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!

Had the battery drain issue with my iPhone SE, but I later realised that the location services and background refresh were the main reason for this whole problem. Try switching location services to be used only when the app is used and switch off background app refresh for the apps which you don't need all the time.

Hi,


same here.

iPhone 6s, being able to run a full day on a 100% charge.

After 11.4 update, on a 100% charge phone is empty, even during the night when not used actively!


Have restarted my phone several times, gracefully and hard, without any result.

Again, on 11.3.1 all was fine!

Battery condition is 83%, which looks ok.


Location services have been drilled down to the bare minimum, similar to background sync.

In my case Mail has used 53% of the battery in the last 24 hours.

I tried to find the push interval setting, but that seems to have disappeared?


I hope this is a bug which can be fixed with 11.4.1...

Same here. I'm very strict when comes to services enabled on my iPhone 6s so the battery usually lasts for over 24h if I don't use Maps. After the upgrade to 11.4 I have 2% of my battery after 11 hours. It now lasts less than half of the original time it did before the upgrade.

There’s more to the conversation

I have the same issue.

When I look at my battery performance, it shows that the personal hotspot on my phone is being used, though I have never turned it on. I have to keep charging my iPhone every 2-3 hours now.
