IOS update 12.3.1 now Battery draining

I called apple about my battery and they said that they haven’t received enough reports of the battery problem so everybody needs to call in and get everyone else they know to call in because this is ridiculous what they are doing to us!

Discharge rate on 7 Plus is quite variable but frequently runs down rapidly when not in use. Will often run down below 20% in the course of a day, previously very unusual unless in heavy use. Battery health shows 91% and capable of supporting peak performance.

I am having horrendous problems with my iPhone 7 battery. Apple had better not even think about passing about the buck on this one and blaming the 2yr old battery. It was performing perfectly well until the 12.3.1 update last week, but it now drains within 2-3hrs after only using Messenger, 20min of YouTube and 30min on Safari.

any news on a fix?

i take great care of my iPhone XR and don’t use it much during the day. Battery has always been fine. All of the sudden I update 12.3.1 and the battery is draining quickly. It’s at 70% within an hour even after only using it for ten minutes. Also, my chargers aren’t working or my phone still dies while charging.

Yes, my iPhone 7 has had terrible battery life since I installed the 12.3.1update. Post update, my phone regularly goes from 100% charge to less than 20% in less than 6 hours with almost no usage. (battery health shows 89%)

Since the last update, my battery is almost totally drained when I wake up in the morning. Even if I click the button on the side of the phone to put it in standby mode before I go to sleep.

This didn't happen at all before the update - I would read before bed, put the phone down on my night table, wake up, and the phone would be down to maybe 78 or 80% battery left. Now with this latest update, I pick up the phone in the morning it's down from close to 100% to <20%, or almost dead.

Something is definitely wrong with this update - it is letting whatever apps have not been shut down continue to drain the battery even while in standby mode. The culprits on my phone are Twitter and the like, though my battery settings did say Siri was the major user for one of the hours while I was sleeping - very strange.

The solution is that with this latest update in terms of battery use. It seems I have to turn off all applications or they will continue to drain the battery even while I am sleeping with the phone in standby mode.

Apple if you are listening, please fix whatever is causing this!

iPhone 6, 1yr old battery (100% max capacity, supports peak performance), background app refresh off.

Battery drains from 100% to 65% within 2-3 hours without *any* activity.

Sometimes runs hot with activity (eg, checking voicemail), accelerates battery drain.

No such issues before 12.3.1

Yes! iPhone SE. Yesterday I picked up my phone which had been sitting on my desk all day unused and it was down to 12%. When I checked battery usage 65% of that was from Messages. This morning my phone had gone overnight from fully charged to 11% and 45% of usage was battery. I’m glad I found your question! Rebooting the phone by holding the power and the home button for several seconds will help for a while.

IOS 12.4 beta 5 has been released as well which means within upcoming week or two the official update will be out. Make sure to do it connected via iTunes and lets hope the issue will be hopefully fixed back to normal for all of us..

I’ve turned off all notifications for everything even ringtones and message tones. I shut off refresh background. I have no reason for my battery to go from 100% down to 8% in 15 minutes!!! There’s zero reason for this!

Considering 12.3.1 is an update that is already in the market, I’m unsure why users can’t discuss current issues with this update here...the developer forum is for updates that are currently unreleased to the wider public?

iOS 12.3.1 *my battery in less than two hours even at night when the phone ain't awake. It can drain more than 50% of my battery before morning and list home and lock screen or Siri as the parasite or whatever that is. Please fix as soon as possible I'm hating my phone or iPhone in general this time.

I recently upgraded my iPhone 7 plus to 12.3.1 and the battery started to drain very quickly as mentioned in this thread. I called Apple Support and they are not aware of this issue. If you have a couple of minutes, I recommend calling them to let them know so that they can escalate the issue. The only solution they could offer was to try factory reseting the phone.

I had the same problem and posted earlier in this thread. I had to completely wipe my phone and restore 12.3. That resolved my issue and my battery life is back to normal. The real pain is restoring all the apps, etc. Apple is starting to get on my bad side! Not sure my next phone will be an Apple!

Yep yep yep I did the EXACT same thing I had to downgrade to 12.3 and so far my phone is working normal again and yes since my last backup was of course with the 12.3.1 I couldn’t use it so I had downloaded everything again :(
