ios 12.4.5 battery drain on iphone 6

Same here. 12.4.5 is killing my iPhone 6.

• Performance-wise: horrible. 12.4 was faaaaaaar far better. Updating to 12.4.5 made my phone instantly a brick in comparison.
• Battery life: horrible. I'm charging it 3 times a day. (My battery is pretty new)
• Third party apps/games stutters like crazy.
• Random iOS crashes too.

Yea my phone goes from 100% charged to dead in 30 minutes. Every time there’s a update battery life is always affected. I do a lot of business calls and check stocks on my phone and I can’t do anything.

I found a fix last night. Charge your phone to 100%. Than stay on your phone till it drains your battery to 10%. Than turn your phone off and wait 2 minutes. Than turn your phone back on and you should have your right charge back. If not turn your phone off for 2 minutes again. And when you do get your charge back use your phone till it’s dead and won’t turn on. Then charge your phone till it’s 100% than it’s fixed

Same here! iPhone with 12.4.5 and 100% battery performance (iPhone 6 replaced via waranty program) and I need charme my phone 3 times peer day. In flight mode when I sleep, 30% of the battery disapeared... Can confirm if your System files always change the size? Sometimes I have 8GB, others 10, others 13GB and this is always change size.

PS: in my iPad with this iOS version, the system files size change too.

Hey there,

Firstly, check your battery health from settings. if it is any below 80% thats the first cause.

Beyond that, i think the apps have gotten heavier for iPhone 6. that is an add on reason why the battery drains a lot, im sure the phone heats up on shortest notice.

try replacing the battery and if not it may be time to upgrade. I had similar issues on my iPhone 7 as well and finally i upgraded and i must say its a big relief.

My battery's health is 100%. My phone was replaced a week ago. This is a new installation, it is not a restore backup and I currently do not have any applications installed to track programs. Nothing. Tonight I lost 25% of the battery while I was sleeping. And the phone was in flight mode.

It’s the 12.4.5 update. I have 2 iPhones 6 and one is on 12.4 and works perfectly. And my other one I updated it to 12.4.5 and the battery drains extremely fast. I even replace the battery and still doing the same.

Apple will never fix this problem. It is already discontinued software and as such, they will not give any importance. My iPhone lost 30% of battery less than 1h. This iPhone is useless. I’m going to work and my battery will drain in 3h.

This is just apples way to force customers to upgrade and buy a newer phone. Apple was already fined for slowing down older iPhones. But the only that’s going to happen is apple is going to lose a lot of customers. Eventually people are going to get tired of all the so called bugs when they come out with a new update and stop buying iPhones.

Can you test something? Go to Settings / General / iPhone Storage and see how much the system storage occupies. My system is always changing that value. Sometimes, iPhone storage is full and the system has 12 GB in use. The more space I have on the iPhone the more the system consumes. An hour later, my iPhone's storage on the system is 6 GB, for example. It is always to change this value and the battery of the iPhone disappears so fast ... I would say that in normal use it lasts a maximum of 3 hours. I lose 30 to 40% battery every night, with it in airplane mode. I think this problem is related to the system. It doesn't make sense that iPhone system storage is constantly changing. I have to constantly charge the iPhone, or I run out of battery.

I have that same problem and also my iPhone 6 suddenly turns off when reaching around 10% battery.

Anyone has a fix?

Same. Within 30 minutes, my battery decreases by around 20%. It also seems that the lower my battery percentage becomes, the faster the battery drains.

Same here. Before this updaet, my iPhone 6 needed to be charged only once a day. Now it needs to be charged several times a day, even if I'm not using it.

Never mind still doing the same thing not a fix

Hey... I’m sorry I wasn’t aware of the rest of the details. You might want to check with the Apple support regarding this. It may be a hardware issue.
