CPU slow when battery low!
This week I’ve placed 4 new OEM batteries into 4 iPhone 6S’s. All 4 customers came back with the same issue: when the percentage goes below 20%, the phone starts to lag so much they cannot use it anymore. As soon as it is plugged into a charger, the issue disappears.
For the past 7-8 years, i’ve been repairing iPhones, and last year alone I’ve replaced at least 70 iPhone batteries without any complaint. January and february i didnt do any repairs because of work abroad, and now in march i get all this trouble. Could this be because of iOS 11.2.6? Is this an extreme case of CPU throttle? How can i reset this? Will iOS 11.3 fix this?
I hope someone can clear this out because this seems like Apple trying to eliminate 3rd party repairs!
Thank in advance
Ist dies eine gute Frage?
