Dan Pražák We have already written several times about the fact that a worn battery causes the iPhone to slow down. Quite a lot has happened since December, when the whole case took on a life of its own. A year-long campaign for discounted battery replacement began, just as Apple's sniffing around the courts began. Going back to the iPhone, the vast majority of users today think about the slowdown. However, few people can translate the abstract term "slowdown" into practice. If you've been using your iPhone for several years, sometimes you won't even notice the slowdown as it comes gradually and the behavior of your phone may still seem the same to you. Over the weekend, a video showing this slowdown in action appeared on YouTube.

David Hanak It was published by the owner of an iPhone 6s, who filmed a two-minute sequence of moving through the system, opening various applications, etc. First, he did everything with his phone, which had a worn battery, after replacing it, he performed the same test again, and the video clearly shows how the replacement the battery affected the overall agility of the system. The author tracked the test, so you can also compare the times he needed to perform the actions on the top of the video.
The sequence of opening applications was more than a minute faster with the new battery. The results in the Geekbench benchmarks also rose significantly, when the phone with the old and worn battery scored 1437/2485 (single/multi) and then with the new 2520/4412. These performance issues have been talked about for a long time, but this is probably the first real video showing the problem in action.

If you have an older iPhone 6/6s/7 and you're not sure if your battery life is limiting you in any way, the upcoming iOS 11.3 update includes a tool that will show you the "health" of your battery. There is also an option to turn off the software slowdown, although this risks system instability. However, a newly added tool can help you decide whether or not to get your battery replaced. As it turns out, this action could significantly extend the life of your iPhone, as it will restore it to its factory-smooth state.

I wonder if the new battery will prevent it from being turned off in the winter? And if it will be of better quality than the original and will last longer in the phone.
They changed my battery over a year ago (12/2016), it shut off in the winter. After the replacement, everything is OK, even today.
Yes, it will prevent. Own experience with iP 6+. The difference in speed is also big.
Again, I wonder if it also applies to the iP SE. At the beginning of the "affair" he was mentioned among the affected, now he has not been for some time. In iOS 9, at least the apps that accurately informed me about the condition of the battery (Battery Health and Coconut Battery) - the number of cycles, the actual capacity... Then they cut it with 10 and suddenly there is a problem :(
My current results are:
My results in measuring the iPhone 6s (I probably got a new one as part of the warranty a month ago):
Single Core: 2539
Multi Core: 4422
For the iPhone 8 comparison:
Single Core: 4038
Multi Core: 9504
Types of measurements after closing all applications (at least what the user is able to do by double-clicking and dragging the application to close):
Iphone 6s:
Single Core: 2533
Multi Core: 4440
iPhone 8:
Single Core: 4163
Multi Core: 10243
