CUPERTINO (AP) — Apple is blaming a software bug and other issues tied to popular apps such as Instagram and Uber for causing its recently released iPhone 15 models to heat up and spark complaints about becoming too hot to handle.

The Cupertino, California, company said Saturday that it is working on an update to the iOS17 system that powers the iPhone 15 lineup to prevent the devices from becoming uncomfortably hot and is working with apps that are running in ways “causing them to overload the system.”

Instagram, owned by Meta Platforms, modified its social media app earlier this week to prevent it from heating up the device on the latest iPhone operating system.

Uber and other apps such as the video game Asphalt 9 are still in the process of rolling out their updates, Apple said. It didn’t specify a timeline for when its own software fix would be issued but said no safety issues should prevent iPhone 15 owners from using their devices while awaiting the update.

“We have identified a few conditions which can cause iPhone to run warmer than expected,” Apple in a short statement provided to The Associated Press after media reports detailed overheating complaints that are peppering online message boards.

The Wall Street Journal amplified the worries in a story citing the overheating problem in its own testing of the new iPhones, which went on sale a week ago.

It’s not unusual for new iPhones to get uncomfortably warm during the first few days of use or when they are being restored with backup information stored in the cloud — issues that Apple already flags for users. The devices also can get hot when using apps such as video games and augmented reality technology that require a lot of processing power, but the heating issues with the iPhone 15 models have gone beyond those typical situations.

In its acknowledgement, Apple stressed that the trouble isn’t related to the sleek titanium casing that houses the high-end iPhone 15 Pro and iPhone 15 Pro Max instead of the stainless steel used on older smartphones.

Apple also dismissed speculation that the overheating problem in the new models might be tied to a shift from its proprietary Lightning charging cable to the more widely used USB-C port that allowed it to comply with a mandate issued by European regulators.

Although Apple expressed confidence that the overheating issue can be quickly fixed with the upcoming software updates, the problem still could dampen sales of its marquee product at time when the company has faced three consecutive quarters of year-over-year declines in overall sales.

The downturn has affected iPhone sales, which fell by a combined 4% in the nine months covered by Apple’s past three fiscal quarters compared with a year earlier.

Apple is trying to pump up its sales in part by raising the starting price for its top-of-the-line iPhone 15 Pro Max to $1,200, an increase of $100, or 9%, from last year’s comparable model.

Investor worries about Apple’s uncharacteristic sales funk already have wiped out more than $300 billion in shareholder wealth since the company’s market value closed at $3 trillion for the first time in late June.

PALO ALTO — The curtain is finally coming down on Netflix’s once-iconic DVD-by-mail service, a quarter century after two Silicon Valley entrepreneurs came up with a concept that obliterated Blockbuster video stores while providing a springboard into video streaming that has transformed entertainment.

The DVD service that has been steadily shrinking in the shadow of Netflix’s video streaming service will shut down after its five remaining distribution centers in California, Texas, Georgia and New Jersey mail out their final discs Friday.

The fewer than 1 million recipients who still subscribe to the DVD service will be able to keep the final discs that land in their mailboxes.

“It’s sad,” longtime Netflix DVD subscriber Amanda Konkle said Thursday as she waited the arrival for her final disc, “The Nightcomers,” a 1971 British horror film featuring Marlon Brando. “It’s makes me feel nostalgic. Getting these DVDs has been part of my routine for decades.”

Some of the remaining DVD diehards will get up to 10 discs as a going away present to loyal customers such as Konkle, 41, who has watched more than 900 titles since signing up for the service in 2006. In hopes of being picked for the 10 DVD giveaway, Konkle set up her queue to highlight for more movies starring Brando and older films that are difficult to find on streaming.

At its peak, the DVD boasted more than 20 million subscribers who could choose from more than 100,000 titles stocked in the Netflix library. But in 2011, Netflix made the pivotal decision to separate the DVD side business from a streaming business that now boasts 238 million worldwide subscribers and generated $31.5 billion in revenue year.

The DVD service, in contrast, brought in just $146 million in revenue last year, making its eventual closure inevitable against a backdrop of stiffening competition in video streaming that has forced Netflix to whittle expenses to boost its profits.

“It is very bittersweet,” said Marc Randolph, Netflix’s CEO when the company shipped its first DVD, “Beetlejuice,” in April 1998. “We knew this day was coming, but the miraculous thing is that it didn’t come 15 years ago.”

Although he hasn’t been involved in Netflix’s day-to-day operations for 20 years, Randolph came up with the idea for a DVD-by-service in 1997 with his friend and fellow entrepreneur, Reed Hastings, who eventually succeeded him as CEO — a job Hastings held until stepping aside earlier this year.

Back when Randolph and Hastings were mulling the concept, the DVD format was such a nascent technology that there were only about 300 titles available at the time.

In 1997, DVDs were so hard to find that when they decided to test whether a disc could make it thorough the U.S. Postal Service that Randolph wound up slipping a CD containing Patsy Cline’s greatest hits into a pink envelope and dropping it in the mail to Hastings from the Santa Cruz, California, post office.

Randolph paid just 32 cents for the stamp to mail that CD, less than half the current cost of 66 cents for a first-class stamp.

Netflix quickly built a base of loyal movie fans while relying on a then-novel monthly subscription model that allowed customers to keep discs for as long as they wanted without facing the late fees that Blockbuster imposed for tardy returns. Renting DVDs through the mail became so popular that Netflix once ranked as the U.S. Postal Service’s fifth largest customer while mailing millions of discs each week from nearly 60 U.S. distribution centers at its peak.

Along the way, the red-and-white envelopes that delivered the DVDs to subscribers’ homes became an eagerly anticipated piece of mail that turned enjoying a “Netflix night” into a cultural phenomenon. The DVD service also spelled the end of Blockbuster, which went bankrupt in 2010 after its management turned down an opportunity to buy Netflix instead of trying to compete against it.

Even as video streaming boomed, movie lovers like Michael Fusco stuck with the DVD service because it still offered films that were no longer shown in theaters and couldn’t easily be found in stores. When Netflix announced its intention to close the DVD service five months ago, Fusco expanded his subscription plan so he could rent as many as eight discs at a time at a cost of $56 a month.

Fusco, 36, got his money’s worth, especially in August when he watched 32 DVDs sent to him by Netflix.

“I was very strategic,” said Fusco, who also thought carefully about what films to pick as his final selections after watching more than 2,400 titles during his 18 years as subscriber. The Southern California resident is now awaiting a Spanish comedy, “Solo Con Tu Pareja,” as his final disc and also set up his queue to highlight films by Harrison Ford (“Mosquito Coast”), Tom Hanks (“Joe Versus The Volcano”) and Arnold Schwarzenegger (“Twins”) should he be among those picked for the final 10-disc giveaway.

Randolph and Hastings always planned on video streaming rendering the DVD-by-mail service obsolescent once technology advanced to the point that watching movies and TV shows through internet connections became viable. That expectation is one of the reasons they settled on Netflix as the service’s name instead of other monikers that were considered, such as CinemaCenter, Fastforward, NowShowing and DirectPix (the DVD service was dubbed “Kibble,” during a six-month testing period)

“From Day One, we knew that DVDs would go away, that this was transitory step,” Randolph said. “And the DVD service did that job miraculously well. It was like an unsung booster rocket that got Netflix into orbit and then dropped back to earth after 25 years. That’s pretty impressive.”
