Battery 11.3.1 again...

[ramses2005]

Hello, Im currently tired of commenting, asking, and seeing this issue all over the place. I dont really know what is happening in Apple but it seems that Battery is not getting fixed anytime soon. My iphone 7 is about 1 year old, and since ios 11 I get quick drains of battery (about 10%) within minutes of use.

Sadly I thought that this was getting fixed on iOS 11.3.1 but it keeps heating up a lot and then theres the drain. Battery health apparently 86% which is quite fair, but I dont really think it reflects its performance. Also im afraid about damaging the battery when the phone heats up while using safari or just texting someone.

Battery health at 86% is actually quite poor. Once the battery reaches 80% health, it has used up its useable life. Batteries are only really good from 80-100%. Batteries are merely chemicals. Once they reach 80%, they become unstable. This is why lithium-ion batteries are rated for x amount of cycles at 80% health remaining. iPhones are 500, iPads, and Macs are 1000 cycles.

This has nothing to do with 11.3.1, but your battery is on it ways out. Take advantage of the $29 replacement before the end of the year and it will make a huge difference. Once a battery drops below 90% its noticeable that its beginning to degrade.

Also with that being said, if you have a Mac, try using Coconut battery to determine battery health. It may be worse than 86%. Apple's battery health is still in beta, and its proved not to be all that accurate thus far.

I'm sick and tired of seeing these comments. My 6s had no battery drain issues on iOS 10.3.3. Battery drain started immediately after upgrading to iOS 11. My battery was at 86%, so I had Apple to replace it. But despite having a brand new battery, there were no noticeable improvements in battery life. Not at all. Zero. At that time, it was still possible to downgrade to 10.3.3, which I did, and that completely solved my battery drain issues.

I saw pretty much the same thing with my son's 6s. His battery was at 92%, and against my advise he decided to upgrade to iOS 11. His battery usage dropped from around 6 hours on iOS 10.3.3 to under 5 hours on iOS 11. Upgrading to iOS 11.3 made battery drain even worse, I think he now has under 4 hours of usage.

The bottom line, yes, sure $29 for a new battery is a good deal, but don't hope too much for any noticeable improvements in battery life. It's not a hardware problem, it's iOS 11.

1.5 year old iPhone 7 here with 86% battery health. I’m getting fantastic battery life on iOS 11.4 beta. Typically get 7-8 hours usage (mostly on screen) and 24 hours standby.

Sounds like something is wrong with your install or an app is going haywire. Certainly not normal behavior.

Like @Mlrollin91 suggested, I would verify that your battery really is at 86% and not worse if you have access to CoconutBattery (Mac app). If it really is 86%, your battery is not on its way out and you’ve got plenty of time to get it replaced before the year (and $29 deal) are over.

My battery is just about where yours is on my iPhone 7 (just went down to 85% a day ago, after showing 86% and 87% at times over the last few weeks) and I'm usually getting about 5-6 hours of usage (also mostly on screen) with about 16-20 hours of standby, depending on the day. This is on iOS 11.3.1 currently, but those numbers have been fairly similar with iOS 11.3 and a bit better earlier, at least partially if not mainly likely due to the battery being in somewhat better health before.

[doublepost=1525429903][/doublepost]My 7 plus battery has been fine for over a year until I updated 11.3.1. It is down from100 to 73 in a couple hours. Would never drain that much before. I have seen a couple articles stating this is a bug. Not enough info is out saying that it is an issue yet. Don’t need this 2 weeks before I travel to Disney!

I've found that when updating (with betas), if I don't do a restart of the phone after the update, that I get pretty crazy battery drain as if something is running in the background post-update. I've gotten into the habit recently of doing a forced restart by holding the home and power button on my 6S. Seems to help.

That said, battery life is not great, even with a relatively recently replaced battery.

No issues at all here on iOS 11.3.1.

Assuming your battery is healthy, all I can suggest is go through iOS and switch things off you don't use (location services etc.). Every little helps (and it does...I've tested it).

The fact that we have to turn stuff off is ridiculous. Anyways i have everything off and 8 plus drains to 0 in about a day and a half just sitting there.

My 3GS from 2009 running iOS 6.1.6 was charged about 5 days ago and still 80% on the charge. Been using it as a music player/game.

Cellular activity is the second largest battery drainer (screen brightness is number 1). The fact that your 3GS is not connected to a cellular network is the exact reason why it can last so long. iPhones have a 10+ day standby time. Turn everything off and it will easily last 2 weeks. If you have 1-2 bars of service, your battery will drain within 10 hours - no matter what.

My battery is also awful with my 6s+ on 11.3.1 especially when watching youtube videos again. My battery % seems to not be calibrated accurately as well. When I restart the phone, I always have 20-30% more % than before I restart it. I tried to re-calibrate multiple times, but no luck.

Sounds like the battery might not be in that good of a shape.

Not a calibration issue, more of a degrading battery issue.

ive been at 4-5 bars and even stuck it in wifi calling mode (wifi on, airplane mode on)
Also, keeping it on airplane mode with no cellular connectivity to get the 10+ days standby time is pretty extreme.
Anyways my mum's 5S on iOS9 does 7-8 days no problem. Everything is on. The 3GS with no cellular connectivity does last 14-25 days however. (it's currently sitting at 75% on day #5)

The A11 in the iphone 8 plus is supposedly more power efficient and the battery (with the screen off) is twice the size. The fact that it'll only last 1.5 days when im barely using it is an issue no matter what. My friend's 8 plus also only lasts 1.5 days.

I can easily - easily get 2 days out my 8Plus with 12+ hours if usage. And I play Pokemon Go.

This is the another problem. It's 1.5 days whether i use it or not. In most cases, the usage time is basically the same as the standby time which suggests there's processes running in the background. The only way for this not to happen is if i remove every single app/ turn off iCloud/iMessage,etc and just use it as a dumb phone.

If you have snapchat, instagram or facebook/facebook messenger, that is likely your problem. They continue to run in the background even with background app refresh off and the app closed. Its not a "dumb phone" you just need to find the cause of the problem. iOS will hardly have things run in the background, more times than not, its a third party app issue.

To be fair, while some people might have those type of issues with those apps, I have them and don't have them running or using up resources unexpectedly. It's certainly something worth checking out, but isn't necessarily behind it all. And at times something from iOS or iCloud or a mail account or something of that nature could be behind it.

Those apps have been a problem for me for 5+ years now. I''m not claiming that it is the only reason for battery issues, but it is a well known issue. But the issue is definitely not iMessage as the poster is trying to claim. Calling it a dumb phone is a bit overdramatic.

I think people also need to look at Search - what is being indexed to be found and also location permissions if they are having battery issues

I don't use any of those, but just for the sake of knowing, Snapchat/Instagram ignore the background app refresh too? I thought Facebook was the only one that did.

How do you know if facebook/messenger/instagram is draining your battery? Under battery stats I suppose?

Both under battery stats and by paying attention to it (i.e when you are using those apps you realize that your battery life decreases faster.)

Yes. I constantly have background Snapchat usage. I always force quit the app when I’m done with it. BAR is off as well

Wow that sucks. Yet another reason not to use them.
