Question: 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?

I was thinking the same thing! I update to 13.2.3 yesterday, today at work I took my phone off the charger. I left work at 5 and it’s now 5:57 and I literally have 83% down from 100%. In the pat I would still be be in the 90% at the time, something is definitely up!


Anyone else having the same issue?

I totally support what you are saying ,I spent 90 mins on the phone yesterday to a person and then a manager in cork, and at the end of the call I gave up as they just said the diagnostics say it’s your battery we don’t have any issues with our software. This is not support it’s just rubbish. I said if it no better with a new battery would the refund me the cost they said no get a new phone.

Battery drain problem still there on my iPhone 7 too. Also runs hot a lot of the time. Unit is 1 year old (they gave me a new one at the Apple store when they couldn’t fix my old one) so definitely nothing to do with battery health of the device itself.

The Lithium Ion Battery in the iPhone can be damaged from heat or cold. After some time the battery can lose its ability to hold the max amount of charge. You can schedule a battery replacement at this website: https://support.apple.com/iphone/repair/service/battery-power.

I don’t think it’s a battery degrading issue. My iPhone X was perfectly on until I updated to iOS 13.2.3. What ever they implemented into this update is draining the battery faster than it should. I recalled that the previous update there were complaint about apps being force closed. This time around whatever was done to solve that issue is causing things to run longer and drain.


I never had an issue with any of the iOS 13 releases until 13.2.3.
