iOS 13.2.3 battery drain

Yesterday upgraded iPhone SE to iOS 13.2.3 - today battery is useless. From 90% to 3% in the morning lost in 2 hours while it was not used at all. Later charged it to 77% and lost in 50 minutes 40% of charge. At least it charges back faster than before but it doesn't help. Can't leave home/office without power bank today. Just yesterday I could charge it full in the morning and it was ~15% left when came home 12 hours later.

The battery drain has gone from bad to worse on my iPhone 6S ever since iOS 13.1.2 was introduced. With iOS 13.2.3 the battery has drained from 100% to 1% in 2 hours without the phone being used at all. If I turn off the phone when the battery is at 100% and then turn it back on, the phone will flash the low battery warning and then go dead. Once I plug it into an electrical outlet, the phone will show that it is charged 100%. The same thing happens if I reboot by pressing the home and power buttons simultaneously. These iOS updates are destroying the battery. It was at 96% capacity when the problems started. In one day it dropped to 95% and then a couple hours later to 94%. I have gone to the Apple store and called telephone support. The employees act like I am the only one with battery issues. The employee at the Apple store told me to recalibrate the battery by letting it discharge completely before recharging. If that didn’t work, then restore the phone. If that didn’t work, then buy a new battery. If that didn’t work, then buy a new phone. Seriously? Is this the advice Apple is training its employees to give?

After leaving it on charge all last night I unplugged it at 08:00 and the still have 71% left on the battery and have just made a 20 min phone call. not sure what is happening but seem to remember this happened a while ago, after being told to get a new battery by apple. whats going on with this software.

I’m suffering battery problems too, I have an SE and my case is a little bit weird because I use the camera, games, play videos and the battery discharges at a normal rate (a little bit more than with IOS 12) but when I read something in the web like for 10 minutes, my battery goes from 85 to 69 in that time 🤷🏻‍♂️, it only happens sometimes tho, not always but it’s weird. My new iPhone Xs will arrive soon, and I think I’ll not going to upgrade until this battery problems are solved.

Unfortunately old devices will have more problems in the future, especially the battery. We have some solutions to this problem.

1.Downgrade your iOS version.

2.Don't update your device.

3.Buy a new iPhone.

4.Reduce battery draining by disabling Siri, graphics effects, background app refresh, data when your are not using your device, update apps, and maybe those methods will help in some manner improve the battery life. Sometimes after an iPhone update, battery is draining because a lot daemon services like rebuilding the index of all of your files for example, can influence a lot.

I hope Apple will help clients that are stuck with old devices and the new iOS can adapt more easily to these. But I far as I know the changes that they will made to system will be more power demanding. Unfortunately I can’t downgrade to iOS 12 last version so you will be stuck with a useless device.

Good luck.

For me, it's something to do with location services. After applying 13.2.3, I watched my battery drain 1% every 5 seconds or so as many have said. I have an app called Sweatcoin which gives you stuff for merely letting it monitor steps. It has 2 modes, a normal mode where you lose some steps called battery saver, and a second mode where it does more location services to verify steps. Before 13.2.3, my battery would (just barely) last all day. After 13.2.3, it wouldn't last even 30 minutes. I turned on energy saver within the app which uses location services a lot less, and, voila, battery back to normal. So, it seems in this case at least it's more an app issue (or perhaps it is IOS just affects some apps differently). I'd suggest trying to turn off location services for various apps and see if you can find one that causes the drain.

I'm having the same issues!

I noticed my battery went from 100% down to 95% with only 15min's of use! This is extremely frustrating and unacceptable!. How can Apple release such flawed and buggy software and think it acceptable, particularly with the premium they charge for their products! If the OS is not ready, don't release it!!

My batteries heats up regularly and the phone is warm to touch, since upgrading to the 13.2 and subsequent updates. i'm constantly restarting/resetting my phone. It killing my battery!!

I use my phone constantly throughout the day for work and rely to my phone battery. Now I will need to have my phone tethered to a power bank to get through a meeting, let alone the day!! Tim Cook are you having to do this, would you think this is acceptable?

Just as another example of how bad this is! I just charged my phone to 100%, unplugged it then looked away for 3-5 mins, the battery is down to 95%! This is Crap!

Wow, your problem is worse than mine. I have an iPhone 7. It seems to have been worse with the battery draining right after I installed the update but still not as good as it was. My phone is getting warmer than normal though and a few games I play and I have to watch ads, the ads won't load (I don't really watch them) so I can't play the game but I am sure it is probably an app problem but maybe caused by these new updates. I don't dare watch any HD videos or the battery will drain quicker I am supposing. I am waiting for the last beta update to come out to everyone. I should have listened and not updated the 13.2.3. The tide seemed to have turned and some sites were saying yesterday morning that this update is better than the last but I found it was worse in terms of the battery problem.

When will apple wake up and address this issue?? My battery on my 6S was fine until I upgraded to iOS 13 and now after a total recharge overnight it lasts about 4 hours.The latest update to iOS 13.2.3 did nothing to help as far as I can see. My battery is just one year old and was showing health as 94% before upgrade now it's showing 92% after the upgrade. Who is kidding who?? new battery, new phone....baloney

I'm having same issue with my X. As soon as I updated to ios 13.2.3 my battery started draining extremely quick. I was hoping it would work itself out after the first couple days as it sometimes does when it's indexing. It will drain itself when I'm not even using it. Before this update I could run a 10 hour day on a full charge & still come home with 30%, now within two hours I'm down to 40%. This is really getting old, Apple needs to get it together. Was gonna upgrade to the 11pro but, I;m losing more & more faith in their competence as superior developers.

Is there an official apple site that we can express our concerns?

I was ok until yesterday night (Iphone XS MAX) I left my phone with 50% battery and when to sleep. After 8 hours the phone has shutdown (not battery) and of course the alarm did not go off (apple watch did nothing!!!!). In the battery app in setting it shows only a rapid depletion without any app in use!!!! Very strange, it seems tha IOS 13.2.3 is doing something in the background which is not reported. Privacy Apple? Real?
