IOS 11.2.5 battery drain

For the second time. It happened last time when they fired him. Apple wasn’t perfect when Steve was running the show, but there was a wholistic theme to the company and all of their products were reliable and trusted. What it’s become is unbelievable. Now it seems like a convoluted mess of decisions that don’t make sense.

Inhave updated to 11.2.6 version but that too didnot solved the problem...

Something really fishy happening in apple..How could they release such

faulty patches? And asking people to replace battery .. Shame on Apple..

Had the exact same problem on my iPhone 7. Battery performance was perfect until the update. Directly after the update battery life was dropping like 10% every 5 min while using the phone.

After reading through all 22 pages here I tried several of the easy mentioned fixes and so far it seems to have helped dramatically. Here’s what I did.

I cleared safari history. I turned IMessage off for about 10 seconds then back on. I went to cellular settings and toggled ALL settings either off then on or on then off again depending on how they were originally set. Then I turned the phone off then on again. So far after 10 hrs battery performance seems much better. Hopefully this may help others here.

Good luck!

I have the exact same phone 7Plus and the exact same problem with the software update draining the battery. I have nothing running in background, don’t back to iCloud and my phone is slower and drains doing nothing.

SOLUTION

ANSWER

Very simple. My IPhone wasn’t timing out. It was always on so biggest battery user was “Home and Lock Screen”.

I think a system update might have set Auto-Lock to Never so the screen never turned off.

I reset Auto-Lock to another value and... lo and behold, the battery ain’t draining.

Next project... is the fridge light really turning off when I close the door?

Latest IOS update never changed my auto lock. It was set at 2 min and remained at 2 min after the update so that wasn’t my issue. It’s been days now since I tried the fix in my previous post (imessage and cellular settings) and while I think the battery performance is still not as good as it was pre update it’s much better than it was.

I also tried changing the auto-lock setting but to no avail. This setting never changed anyway. Also tried to toggle imessages on and off. no difference.

Could someone explain what it meant by 'cellular settings'? I am in the UK. Do you mean taking SIM card in and out?

Also, went into Apple store this afternoon and young guy tested my SE's battery (less than a year old) and it's fine at 102%. So, he advised to do a hard restore next. I will try that when I have a minute.

If this does not work, I would have to have a new battery fitted. Surely that's got to be wrong. My batter is perfectly good, what a lot of waste! What are they even doing with these old batteries? Anyway, what's happening is really bad.

OK, I am trying to change the setting for auto-lock and restarting my phone right now.

The thing is, if the power is draining away while I am just messing around with the general settings, so how could the lock being 'invisibly' set on 'Never' affect it then? My phone is losing power all the time, not just when it's either locked or not.

While I was at the Apple store this afternoon, the young look at it for 10 mins and it had drained by 3% in that time!!

The cellular settings I was referring to has nothing to do with SIM card. Go to settings > cellular. Here you should see cellular data and it’s likely turned on. Toggle off, wait 10 sec and toggle back on. Right below this setting you’ll see cellular data options. Select that and you’ll see enable LTE voice / Data and roaming voice and data depending on what you had your phone set at. Go in to those switches and toggle off / on or on / off depending on how they were set originally. Hope that helps. The cellular settings + iMessage off / on seemed to work for me so far but who knows if it will last. This whole thing is total BS IMO. Apple needs to step up here and let people know what’s going on with this. 23 pages describing the same problem with battery drain directly after a specific update is not a mere coincidence.

I wanted to provide an update on my progress. I had two tasks that I needed

to address in order to determine if the problem I have is fixable, or not.

- Factory Reset my phone completely

- Change out the battery

I've scheduled a battery replacement from an Apple Store (because I don't

want any excuse that the replacement was done by someone NOT Apple, and

that's why my phone battery drainage is so poor). And while they are taking

a while to get back to me, I'm hoping in the next week or two I will hear

back.

I've just Factory reset my phone. No 3rd Party apps exist, and the battery

drain appears to still continue.

So now I'm going to wait for the battery replacement. At which point all my

other options will have ended, unless someone else has any ideas.

6 weeks ago I bought a NEW iPhone 7 and updated to 11.2.5 and I had the problems which are outlined above. I tried iMessage on/off, iCloud on/off, ... and further made a reset. No improvement. I installed 11.2.6. No improvement.

I think the last thing I tried was to set the default time for the lock screen from 1 minute to 30 seconds.

Now my battery-lifetime is normal !!! since 3 weeks.

Cause I tried many things I am not definetely sure that the problem was the lock screen time. But I am sure the problem with the battery is not a hardware problem.

@apple: It's definitely a software problem.

I had the same problem recently. I got on a live chat with Apple support and after a long and tedious troubleshooting session we decided to do a complete restore on my iPhone by hooking my phone up to my MacBook Pro. The battery seems to be working properly again. Apparently, there was a bug in iOS that was causing the problem and I needed to start over by restoring. Just remember to back up your data if you do a restore. Good luck.

iOS 11.3 has the sane problem.

As per the thread, I noticed the app taking most battery was Safari.

i Tried various things like turning off javascript, installing ad blocker, etc. But then installed Dolphin browser and stopped uaing Safari and it looks like my problem is resolved. Safari has some memory leak somewhere.

Hi all!

i am an Apple user for the last 7-8 years and have restore/updated a lot of them. I updated 2 days ago from 10.3.3 to 11.3. I have been afraid of battery drain and now I have this :-( Before in 10.3.3 I used to get 1.5-2 days of battery. Now I recharged my phone over night and unplugged it at 4am. At 8 I was already down to 90% in standby. The battery drain continues. The settings remained the same as before: location off, background app refresh off, iDrive off, only Photo Stream is on.

What I can see odd is that Photos is eating up 47% of my battery, even if it says 2 minutes screen and nothing about background. The next one is Email with10%. With Photos I have iCloud Drive off, backup to iCloud off, just Photo Stream is on.

I am suspecting some sort of background indexing of files because this is not ok at all; battery is draining like crazy. Or trying to reupload Photo Stream - altough on my iPad Mini the photos are uploaded and ok so this shouldn't happen as everything is uploaded.

@Lawrence: I have been reading your posts and they make sense even if I find it weird how an upgrade can mess up syncs as before starting the update the ios closes all running processes, right? Also average users cannot be expected to troubleshoot individual apps like you described as it is very time consuming. Anyways - do you have any ideas to the case described? I also just turned off Siri and Search from looking into photos - I had the suspicion that maybe the ios was reading in the background the photos to try indexing and clustering them in order to offer better search options (like when you type "vacation" in search to offer photos from past vacations).

Thx!

What you are seeing is PhotoStream syncing. That should stop after a few hours. If it continues try turning it off. If that stops the problem turn it back on.

PhotoStream is a deprecated feature as of iOS 10. It will still work, but the better solution is iCloud Photos, as its permanent (PhotoStream images disappear after 30 days or 1000 photos, whichever comes first).
