Apple's decision to nix iPhone 15 button upgrade impacts supplier stock.

Apple's decision to not heavily use Cirrus Logic's haptic touch technology in the upcoming iPhone 15 Pro, as previously expected, has caused a 12% drop in Cirrus Logic's shares. Analyst Ming-Chi Kuo had previously stated that Apple would expand its use of Cirrus' technology beyond haptic touch and replace physical buttons with solid-state technology, but "unresolved technical issues" have forced Apple to abandon the change. This decision is unfavorable for Cirrus Logic and AAC Technologies, causing a drop in their shares.
