Back in late 2017, a Reddit user benchmarked his iPhone prior to and after replacing its battery and found that its CPU efficiency enhanced following the battery modification. Apple later confessed that it purposefully throttled phones with aging batteries and said sorry by using out-of-warranty battery replacements for $29, $50 less than typical.

The CMA examined the problem when it exploded and raised issues that people might have tried to repair or replace their phones if they weren’t conscious that updates could decrease their devices.
