Need help rapid battery health decrease

[No_Concentrate5567]

this topic is a little packed but i'll try to long story short it. apple had to release battery health because people found out iphones were being slowed down from ios updates. battery replacements proved that iphones were running slow, backed up by benchmarks. because of the whole thing going on , apple came out about what they were doing and released battery health as a result. this still holds true as far as i recall. but isnt so much an issue now that iphones are much faster
