I'm curious if this is a case of planned obsolescence.<p>Apple MBP 2015 users with battery replacements from services like iFixit report that their computers start to lock up after operating on the battery and being connected to WiFi. Connecting to external power can immediately resolve this. There are often two or three services that are involved in the slow down, configd being the most common. You can use terminal to try to kill the service, but it is often difficult and the processes will immediately restart.<p>Is there DRM in Apple batteries that after market batteries do not have that may be causing this battery drain?
