Battery issues on iOS 14.6? (iPhone 11 Pro)

tribalflags said:
I used to be on here decades ago but lost my email so joined up again, so hi to everyone!

ios14 has generally been good for me on an iPhone SE 2020, iPhone 12 mini & an iPad Pro 2020.

however , on both iPhones just recently and at different times, the battery would drop by about 30% during the day or night. No changes in my usage. I only have background refresh on for about 4 items and none of which are listed below.

before this battery drain happened, I enabled the new firewall in 1Blocker and noticed that Shazam (the app) was hitting iBeacon constantly even when not using the app. I realise that apps might still use services once you leave them, but this was happening for hours. Soon as I closed (swiped up) Shazam the battery issues vanished (until the mysterious battery drops recently on 14.5.1.)

now, on 14.6, I use BeatHawk(music app). It’s on all my devices and my battery is tanking bad. I’d normally put it down to the new iOS just doing its thing for a day, but I looked in the battery section and noticed that BeatHawk was running in the background the entire time the devices were powered on. Closed it fully and it stopped the drain. Updated the iPad to 14.6 and then opened BeatHawk and this morning it had been running for 14 hours. Must be a bug in beathawk, I think. I’ll contact the devs.

I used to be one who didn’t really turn stuff off, like location stuff and notifications and push, but after getting a bit paranoid watching YouTube the last few months, I started disabling tons of stuff. It made marginally any difference compared to when I had most of this turned on, so it’s been all back on and all is fine. I’d rather have the feature than a half-functional phone.

sorry for the ramble and not sure if this is what’s causing your problems. But once I stopped Shazam and BeatHawk, battery has been good so far. The strange thing about 14.5.1 is that the battery drain only happened about a weeks ago, well after it came out. Maybe it was an app or something.View attachment 1781846

*No on 11, by 12 Pro Max.
- First, I WISH the % Health jumped up on my 6 month old phone..90%! (Many are having this issue now), but without the heating up and erratic battery drain. Sorry

- Second...well battery drain! Yeah after updating to 14.6, my Mail app was at 100% running non stop in the background...and it wasn't open. No push, fetch...nothing! My solution that killed that problem was I toggled on Background App Refresh. Also - in mail toggled on/off Push Fetch.

Did a HARD REBOOT of the phone, this seemed to end the background battery draining problem.

*I still have Find My..App running constantly (I guess this is needed for AirTag?) Also TILE app to keep track os the thin Card sized BT tracking. This doesn't seem to use much battery though.

As annoying as this is - and I do recall LAST summers iOS having Apple Music and for me, Dropbox absolutely killing my battery on XS Max as it ran 24/7 - Uninstall the app, reinstall. Try toggling Background App Refresh off...reboot the phone and see if that helps.
 
The first night after updating my 10.5 pro I apparently woke up and used my iPad for 15 minutes every hour according to the battery monitor. It went from 100 to 40% overnight. Turned it off and on again in the morning. Didn’t rack up any time last night. But battery use does seem to be accelerated over 14.5.1.

good to know, staying with iOS 14.5 all my devices for now till apple sort this battery drain issues.
 
Yes I updated my 12 mini from 14.2 to 14.6 a couple days ago, and in the proceeding last 2 mornings when I woke up i used my phone for a few minutes looking at messages and checking Macrumours, and battery dropped suddenly with the back of phone warming up just like others have reported. School boy mistake on my part, I always check reports of battery drains before updating IOS versions, but didnt this time!
 
iPhone 11 Pro Max with 14.6 and since the update I have been getting unexpected massive battery drain. I’ve also noticed the phone gets warm for no good reason.

With my M1 iPP 12.9 running 14.6 I have no battery drain issues.

Eh! I have seen multiple posts about the drain AFTER 14.6, On XS Max, 11's and 12's
My "health" took another 2% drop in the past 4 days.

This is just dumb, junk quality. I love Apple...but c'mon!!
Sorry to be so blunt...but that's what it is. Apple needs to own up to this mess.

I don’t see a pattern to it. My phone was fine today, and that inlcuded a 46 mile bicyle ride using Cyclemeter, which tracks my ride using GPS (a known battery drain). My iPhone is still at 70%. OTOH, the other day it had run down to 30% by 4 PM for no good reason.
 
It’s similar with my 12 Pro. Everything was fine with 14.5. I’ve had to charge it every second day. Now on 14.6 I’ve problems to get over the day. And funny is that AppleStore app needs the most battery power. Even listening to Apple Music and Podcasts needs significantly more power on 14.6. also the battery capacity drown to 99%.
That’s really annoying.

I replaced the battery on my iPhone X recently and after that had great battery life. It would be at 20-30% late in the evening. After 14.6 it hits red mid-afternoon every day. Even if I charge it then up to 40-50% it will still be at single-digit percentage in the evening. I should add that this is without heavy use of the phone, pretty much the entire day on wifi and only sporadic use of the phone. There is nothing in Settings-Battery to indicate extra power consumption by any app so it seems to do with how iOS handles power usage.

Oh if things could only be like with Catalina which added lots and lots of battery time to my ageing MBPr late 2013.
 
I'm trying a drain to 0% and charging back to 100%. So far, it's been on charger for 3 hours and it's finally at 90%. Good sign, bad sign?
 
12 pro and I wouldn’t say massive drain, but it’s certainly a noticeable battery downgrade from 14.5.1.
 
12 Pro. Phone gets warm and drains battery at an increased rate. Can’t remember which iOS14 version started causing this but I can barely make it through a half day with normal usage now. Never game on it either.

Has anyone tried dev. betas of the iOS 14.7? Any improvements regarding battery?

Beta 1 was not so promising here. Beta 2 just launched on the dev side yesterday, so it is too early to tell on battery. I would follow the 14.7 beta 2 thread, would get more insight within a couple of days.

I just connected my 11 Pro up to a Mac with Coconut battery:
Full charge is higher than designed capacity?

So about a week later it looks like the calculation leveled in Coconut battery...my iPhone's battery health is still at 100% 🧐

Unfortunately, looking at the statistics, the battery is not holding completely 100% that it was designed to hold. Regardless, overall it is mostly all there, so I would not worry about it. Ideally, you would want the battery to report holding the same value as the "Designed" value.
 
Phew, good to hear I'm not alone. The battery drain on my SE 2 has been absolutely massive since I think 14.5 and just gotten worse. I used to get at least a day of battery time with my usage, but now, I'm lucky to get 8 hours (4 hours use, 4 hours no use). I can watch the battery percentage go down just with the screen on.
I keep charging and charging. Last week I've used 120-180% of battery every day, that's totally crazy.
My first thought was that switching carriers on my work SIM card had anything to do with it since it sorta correlate, but now, I'm pretty sure that has nothing to do with it. My private number is on eSIM.

I have 14.7 beta 2 on my iPhone 7 and it still drain‘s the battery.
I had the same problem on 14.6 and thought 14.7 might help but it didnt.
what I see is, that the cpu usage is constant between 70-100% as long as the device is connected to the internet. As soon as I turn airplane mode one, it drops to 5-10%.

When you see the CPU spike, are you actively browsing something, or simply having the phone connected to a network that carries internet data? That is definitely interesting and probably pointing to the issue that so many people are reporting. Have the CPU that high that often will definitely tank the battery and create the most heat.

I downloaded this app https://apps.apple.com/ch/app/system-status-hw-monitor/id407752428 to check cpu usage, cause my phone got hot even with light safari browsing.

I saw that the cpu is always that high and closed all open apps but still got high cpu usage. The I tried to switch off networks and this helped.

you can simply disconnect wifi and switch off mobile data and after some seconds the cpu is down around 10%.

Did you notice this only with Safari? I have seen other opinions on this but I wonder if Safari is the actual offender here. It would make sense as to why there are people who are unaffected. I would try any different browser and see if you can reproduce it, if you like that is. You never know ;)
