San Francisco CNN Business  — 

Despite a year of slumping iPhone sales, Apple chose to largely stick to its smartphone playbook with new models announced at a closely watched press event on Tuesday.

Apple (AAPL) unveiled two high-end iPhones – the iPhone 11 Pro and 11 Pro Max – with four-figure price tags, as well as a cheaper iPhone 11. The models replaced the similarly priced iPhone XS, XS Max and XR, respectively.

In typical Apple fashion, the company played up improvements to the battery life, camera system and hardware under the hood of the new phones. But on the surface, the new iPhones do not look radically different than the previous year.

The iPhone 11 Pro and iPhone 11 Pro Max models feature an improved camera system, with three cameras on the back of the phone, and better battery life than previous models. Apple says the iPhone 11 Pro will last four hours longer than the iPhone XS and the iPhone 11 Pro Max will last five hours longer than the iPhone XS Max.

Apple CEO Tim Cook called the Pro models “the most powerful and most advanced iPhones we have ever built, with a stunning design.” And the company is asking customers to pay up for them.

The iPhone 11 Pro and and the iPhone 11 Pro Max will start at $999 and $1,099, respectively – the same as what Apple charged for the previous iPhone XS and iPhone XS Max.

Apple unveiled three new iPhones -- the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max -- at a closely watched press event at its headquarters in Cupertino, California on Tuesday. The devices feature improved cameras and battery life from the prior year, but no radical redesign.

The decision to hold tight to these prices comes as Apple’s iPhone business has experienced double-digit percentage sales declines in each of the last three quarters. The company is contending with consumers taking longer to upgrade and a trade war denting demand in China, once one of its most promising markets.

Perhaps in a nod to those market challenges, Apple did make some pricing tweaks. The iPhone 11, with a dual-camera system, will start at $699, slightly less than the $749 entry price for the previous year’s iPhone XR.

The new iPhones will be available for pre-order on Friday and go on sale in stores on September 20.

In addition to the new iPhone lineup, Apple unveiled a new seventh generation iPad at the event Tuesday, with a larger 10.2-inch retina display and a price tag starting at $329. The previous model had a 9.7-inch screen.

The company also announced the Apple Watch Series 5, an updated version of its smartwatch with an always-on display. With this feature, the watch face is always visible, rather than requiring the user to raise his or her wrist. The Series 5 watch starts at $399, or $499 with cellular.

As with the iPhone 11, Apple appeared to bow to more price-conscious consumers by announcing that the Series 3 Apple Watch, an earlier version, will now retail for just $199.

In what could be a sign of Apple’s shifting focus, the company kicked off its event by focusing on subscription services, a product area it is increasingly betting on to grow revenue and offset sales declines in its core iPhone business.

Apple unveiled pricing and additional details for Apple Arcade, its gaming subscription product, and Apple TV+, a new streaming service for original shows and movies. Apple Arcade and Apple TV+ will each cost $4.99 a month.
