After 12.0.1 update battery drain is high

My iphone 7 was running perfectly fine, would charge at night before going to bed, then would last all night and day before having to recharge the following evening, since the ios 12.0.1 update, the battery will go from the 90’s right down to 50 odd percent after only about 10-15 minutes of use, i am now having to recharge 3-4 times daily and then the charging process can take hours and my phone will heat up quite a bit too. This is absolutely shocking, Apple need to get their act together!!!!

My phone is up to date (12.0.1). The battery drains so quickly. On top of that it would charge to about 5% then drop to 1%. I would let it charge with the screen off for 20 minutes and it couldn’t reach 10%!

Been with iPhone since original phone came out. First time I am seeing such severe battery drain with my device. Just moved over to iPhone XR from X last week. Therefore new battery and new phone. For 2 days all was working fine and software must have upgraded to 12.0.1. However now rapid battery drain. Face ID also stopped working. No help with hard reset and all the other ‘tips’ to reduce battery life. Charging also appears to have seriously slowed down. Not sure if iPhone XR or software issue. Awaiting 12.1 which I understand may be released today! If problem still occurs then phone will be taken back to network provider as purchased last week!!

It is definitely a software performance issue that’s degrading the hardware performance. Apple please look into this issue as it would not reap good fruits for you in terms of losing good amount of customers.

I am planning to buy iPhone XR, but after this issue, I will wait until this will be fixed in the next update 12.1.1. If it will not, I purchase Xiaomi, Samsung or Motorola and definitely leave apple...

I started having this rapid battery drain issue on my iPhone X for a few days now.

Spend over 30mins with Chat Support without issue being resolved and now have appointment with Genius Bar for next Saturday.

No idea whether it is related to software or hardware....very disappointing!

Same here, 6s. Battery was replaced less than a year ago under the replacement offer they had due to the throttling issue. Not just drain, but if I am watching a video while it is plugged in, it won't charge at all, i.e. the draw on the battery is equal to or more than the charge. That's never happened before. Pretty annoying.

Same issue with me after update my iphone 6 to ios 12.1.1 battery drain very fast...after installation new battery issue is same...i charge my phone 100% at night and switch on flightmode then morning 7am battery on 70 to 80% infact all setting backgroung apps refresh locations closed but still battery draining on standby..PLEASE FIX IT APPLE WITH NEW VERSION OF IOS

APPLE totally failed to resolved battery issue every ios new version damage battery life....i installed new battery in my iphone 6 but still same battery drain issues on standby :( infact all the setting app fresh and location also closed but battery still problem

I use Iphone 6 and the battery says ; Supporting normal peak performance.. but the battery dies in 6-7 hours without any mobile data use while sleeping during the night.

IOS 12.1.1 also has the same issue.

Same issue with me battery draining continues every time infact on flight mode and all settings closed complain lots of time to Apple support on twitter but they dont agree that is ios version they always its battery issue i installed new battery before one moth a go 😑🤭😶 i am think to switch on android after this behaviour from Apple

This issue has increased the last two days and is worse than before. I went from 81% to 35% in a 10 minute drive from my home to where i was headed.

my phone has been locked for an hour and it went from 80% to 1% in that hour.

This is unacceptable. my iphone is not even a year old.

please fix this.

I too have the same problem. I have reinstalled iOS, started from scratch, even re-flashed my iPhone 6s with new firmware to ensure everything was back to "factory settings". I've followed all of the "disable this, and disable that" advice you find in all of these forums. My battery was recently replaced, is operating at 98% peak performance.

But here is the amazing thing: Apple is silent, utterly silent on the true issue. Sure they publicly say to wait until the background re-indexing is finished after the recent upgrade in iOS, or to disable certain features to ensure longer battery times. But all of us on this forum know for certain these are not the culprits of going from 80% to 30% in under an hour of minimal usage.

Apple? Are you there? Do you even care? Or do you at least care to acknowledge something...anything?

One of the saddest things is people spending hours troubleshooting this by disabling common features of their phone, making it more and more unusable, and for what? Most of the troubleshooting tips do not do anything. And the most depressing one: getting a brand new battery installed. That is unacceptable. The advertising for this phone is false when it says 11 hours watching a video.

I’m glad that the Screen Time fix worked for you and yulius123. I’ve had Screen Time disabled for weeks now, with zero discernible difference.

The software problem is far more systemic than disabling any one (or many) settings.
