Slow iPhone? You're Not Crazy, Apple Is Doing It

Apple confirmed what many have suspected: it slows down older iPhones. Here's why.

CUPERTINO, CA — If you own an older iPhone and thought you're phone was acting slow, you're not crazy. Apple confirmed to multiple news outlets that it does, indeed, deliberately slow down older models, but explained the decision as not one to get you to buy a new phone, but rather to prevent problems stemming from outdated batteries.

Apple said in a statement that it wants its customers to enjoy the "best experience," including overall performance and long-lasting phones. Batteries in poorer conditions might not be able to provide the power needed to run the phone’s processor at full speed, leading the iPhone to abruptly and unexpectedly shut down to protect its internal components.

Software updates for iPhones 6, 6S, SE and 7 are meant to smooth out those power demands, prevent shut-downs and prolong battery life.

"Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components."

Eleven days ago, an observant Reddit user noticed the user's iPhone 6S was "very slow" over the past few weeks even after multiple updates. Plugging in the phone didn't help either. After a battery of speed tests, the user concluded Apple slowed down phones with "low capacity batteries" and that they'd only run at fill speed upon replacing them.

Apple said on its website that it'll test iPhones for battery and power issues. Repair fees depend on the diagnosis and whether the issue is covered under warranty or AppleCare+.

"Our warranty covers a defective battery, but it doesn’t cover wear from normal use," Apple said.

Those covered under AppleCare+ will get a free replacement battery if it retains less than 80 percent of its original capacity. Those not covered and who need a battery replacement must pay $79.
