If you follow the and the Apple world as a whole is already fully aware of the politics surrounding iPhones performance reduction because of old batteries. In a nutshell, if you're still lost on this subject: to prevent iPhones with old / worn batteries from turning off by themselves, Apple has decided to reduce their processing power at times of peak power.
The whole problem was that this decision came from Apple without any prior announcement, no warning to customers that if their handsets had old batteries, they could lose performance. No wonder the company is responding to more than 50 processes around the world, being called by governments to explain, etc.
To ease things up, Apple has decided to offer a battery replacement program in which users pay ?only? $ 149 (instead of $ 449) to replace the component and thus get the desired performance on the device. This program is valid for iPhones 6, 6 Plus, 6s, 6s Plus, 7 and 7 Plus all iPhones 8, 8 Plus and X are still under warranty, so the program does not make much sense for such smartphones.
Also to beware, Apple has decided to implement on iOS 11.3 which is still in the testing phase and soon will be released to the general public a feature by which we can disable this reduction in performance (knowing, of course, that the device may turn off even indicating battery power). We made a very complete article about this feature of iOS 11.3, check it out here.
But the question that does not want to silence,: slower Is an iPhone with a dead battery? We already saw benchmarks That's about it, but the overall experience of using the device, as we know, goes far from numbers like that. Exactly why this Bennett Sorbo video is interesting. In it we see a iPhones 6s performing the same tasks before and after changing the battery (yes, we are talking about the same device performing the same tasks at different times with everything properly timed of course).
The tests range from opening applications to browsing Safari. And we see that even for the simplest things, there is a quite noticeable performance difference. Speaking of benchmarks powered by the Geekbench app, the iPhone 6s before battery replacement scored 2,485 in the multi-core test; the same test with a brand new battery scored amazing 4,412 points.
Do you doubt that many will choose to turn off this reduction in processing when iOS 11.3 is released?
