iPhone 6S Battery Drain IOS 12

Same issue here. I obtained a new battery for my 6s this summer after the power throttling controversy and recently updated to IOS12. Immediately, I started having rather shocking battery issues. I can actually watch the percentage drop as I’m using the phone. Worked perfectly before the update. Now, the phone is virtually unusable. I’ve had iPhones since the original, but I think this is going to be my last one. Apple is shady. I can’t help but think this issue was by design to force us to upgrade to new phones.

After the issue seemed to get better for me, yesterday the battery started dropping back again.. Me too I can watch percentage drop by almost 10% in a matter of minutes sometimes, while surfing on safari only on wifi...

And you guys saying that the issue is still there after changing the battery doesn’t give much hope since we are already on ios12.1, so apple should have fixed the issue already if it was their intention.

Just fyi, I replaced my battery this past summer under the very program you described and still suffer from the same rapid battery draining issue after the update. If you haven’t updated to iOS12 yet, I’d be hesitant to do so.

Yeah, don't update. The whole internet says that the 6S is the most stable iPhone ever and Apple knows that. They're trying to make ups dump a good product so their sales go as planned. I really don't want to change mine for a slightly better hardware, because that's the only difference. It's interesting to see so many behaviors of the same device with just a software update. This whole thing is planned for sure. I was lucky to make mine last a little longer with a battery change and if I'll have to give up on it I am seriously thinking about buying another 2nd hand 6S that's still running iOS 11. Just look at everyone having the same problem while Apple is forcing us to buy something new...

Mine is exactly the same as everyone is having issues with its shocking and Apple really need to get it sorted out, it's as if its a ploy to make very one buy a new phone mine was a new iPhone 6s in April and battery life is shocking I have to charge 3 times a day with minimal usage 😡

I did a little test on mine shortly after my last post. Charged 100%, I checked for app updates on the App Store. There were a total of 8. I unplugged the phone and began the update downloads while connected to WiFi. In 3 minutes, I watched the battery plummet from 100% to just 59%! That’s right, just 3 minutes. And this is with a new battery! This isn't a background refresh issue or an indexing issue or any of the other nonsense Apple Supoort will tell you. This is a scam, plain and simple.

i updated my iPhone 6s when the 12.1 update November 8th right away the battery died I assumed that the update took a lot of power during the update. However after recharging the battery died in minutes. I did not use the phone until today after a full charge the battery died with 3 minutes screen time and 10 minutes Screen off.

The battery lasted a full day or more prior to the update. How do I remove the 12.1 update from my iPhone 7 spit doesn’t accidentally get installed and kills the phone as well.

Someone in this article is pointing out that apple screen time feature could drain the battery.

Maybe it would be good to give it a shot and disable the feature to see if it helps.

My phone was also not old (1 y.o.) ans my battery was 89% so in good health.

I changed the battery and did a whipeout of the phone and used it as « new iphone », which helped a bit. I still dont have the battery life I had on ios10.3.3 but it seems better.

Today I got 4h20min screen on time and I still have 28% left. Still not great, but better than the -30% in one minute battery that I had before..

If someone is willing to do a DFU restore and use his iphone as « new iphone » and not restoring from his backup, we could see it this was the main thing that helped my battery (and would help yours) or if it was because I changed the battery.

It is a pain to reinstall everything and relog in every app, but I think a lot of people would prefer this over a draining battery!

Let me know !

For me reducing motion did not really change something after I changed the battery. Neither bacground app refresh. However, maybe it would have helped before I changed my old battery.

How much screen on time arr you getting (not the las 24h but if you count each bar in the battery stats since last full charge)? I get arround 6hours, on wifi, with not a lot of gps and arround 30-40% screen brigtness. For me it is acceptable, but not a bood performance for a 1yo phone with a new battery.

I spent a lot of $$$ on my iPhone 6s three years ago. However, the new upgraded IOS 12.1 has made my iPhone useless. The battery lasts two hours which is unacceptable because I need my cell phone for work. I called Apple support, and the kid was very condescending, and tried to tell me my cell phone battery problem is because I'm on Instagram for a half hour a day. (Even though I told him, it dies quickly even if I don't use my iPhone all). Now realize just like my iPad, Apple products are only supposed to last 2-3 years at most before they become useless. I wish this was made known upfront. My advice to others: don't waste your time trying to troubleshoot this problem because as far as Apple is concerned, it's not a problem. I plan on upgrading my phone today and spending over $1,000!!!! I've been told the Samsung Note 9 does not have these issues.

Before you buy a new phone, I would highly recommand you try this. My battery was dropping by chunks of 30% sometimes after upgrading to ios12. I payed 40$ to replace my battery but I doubt that it is besause I changed it. I think it is more because I did this (I am now able to have 5-6 hours of screen on time, wich is not great but better that 2h..). I urge you to try this before paying 1000$ for a new phone! :

Step 0: save all your files and pictures, make a back up in case it does not work, so you can simply come back to your old disfuctioning phone but with all your data.

1. Do a DFU restore of the phone (check a video on youtube). You need to download the latest ios from itunes and be connected to the iphone with lightning cable befor begining. You need to press and hold home and power button and release the power button while holding home button. A message will appeare on itunes saying an iphone in recovery mode was detected. You need to act fast (lile no more than 2 sec) and click on restore iphone. If the phone wake up and gonto home screen, you were to slow, but if it is restoring, it was ok!

2. Use the iphone as a new Iphone, dont restore from a backup (important as the root of the problem could be in the backup).

3. Under settings, privacy, location, systems services, turn off everything except sos calls and find my iphone (it will not impact anything, its just location data apple uses except for the two I mentionned or if you use the geo fence functionality to remind you of something when you leave a location).

4. Under this same section, go to « important locations » and turn it off (it is always tracking you to know if you are in a big city).

5. Under settings, privacy, location, turn all location in app to « when using app » or off completely.

5. Under settings, privacy, analytics, turn analytics off.

6. Under passwords and accounts, turn off push notifications to recover every 15 min, and change it also for every mail account!

7. Put back your pictures from itunes and redownload every app from scratch (i know it is

Painfull).

8. Cross your fingers and see if it works. If not, the last step would be to change your battery with the 29$ (or 35$ in Canada) program.

It worked for me to have at least 5h-6h of screen on time (with new battery).

I hope it will help others!

Apple really need’s to be careful or it will lose valued cutomers with those issues happening with 1 year old phones!

Peace Y

I recommend you don’t downgrade to Samsung.

You could downgrade your phone, it will void the warranty, but it will make your phone useful. Find a video online and downgrade to a older operating system. As your battery gets older, it will get slower. New batteries are about $29 as they are on sale now.

Hi :-)

Just got a - brand new - 6s on discount plan in italy (love it <3) and experiencing the same :-((

Bad battery life with all important settings right (Background App refr. Off and all usual tips, brightness, motion, visual effects ecc.)

Nice to know it's not only my device and hoping Apple will fix it soon seeing one of iOS 12 strengths is indeed that it runs great on older devices (iPhone 6 too as shown on launch)

Waiting for next updates..!

Yes the exact same thing is happening with me. I upgraded my phone (which was working optimally) and gave my son my 6s and he updated to iOS 12 and now the battery drains RAPIDLY. He missed an appointment as a result this morning because it lost all power and his alarm didn't go off! APPLE PLEASE SORT THIS RAPID BATTERY DRAIN ISSUE ASAP! I will be posting to all on twitter as well to see if anyone has a workaround.
