Apple Inc unveiled the iPhone 13 and a new iPad mini on Tuesday, expanding 5G connectivity and showing off faster chips and sharper cameras without raising the phone's price.

The Cupertino, California-based company did not announce any blockbuster features or products, but analysts expect customers hanging onto older models like the iPhone X will be eager to upgrade. To encourage trade-ins, participating wireless carriers are offering incentives ahead of the year-end holiday season that to make the new phones free to some customers.

The iPhone 13 will have a new chip called the A15 Bionic that enables features like automatically translating text. The phone also has a better display, longer battery life and a Cinematic mode for automatically changing focus while taking videos. Apple said the iPhone 13 will have custom 5G antennas and radio components for faster speeds and will come in five colours.

The phone will start at $699, and participating wireless carriers will offer up to $700 off for qualifying trade-ins. The iPhone 13 Pro starts at $999 and the Pro Max starts at $1,099, with trade-in offers of up to $1,000. All three models will be available on Sept. 24.

The iPhone is Apple's most important product, but Apple has rolled out a web of service and other products that are seen as locking customers into a system they enjoy -- and would find expensive to leave.

The Series 7 smartwatch will feature a larger display and faster charging. It will start at $399 and be available later this autumn.

The company also updated its iPad Mini with 5G connectivity and a reworked design that makes it look like the higher-end iPad Air and Pro models. Bob O'Donnell, head of TECHnalysis Research, said the small tablet was Apple's most surprising announcement and could lure in customers who want a device with 5G that can handle more powerful apps than a phone.

"I don't think it replaces any other device, like we've seen Apple try to position some of the bigger iPads as PC replacements," O'Donnell said.

The new iPad Mini's price rose by $100, but it also added new capabilities like compatibility with the company's Apple Pencil and a faster chip than the larger-screened base model iPad, bucking a trend of smaller screens being cheaper. Apple showed the Mini in use by professionals like doctors.

Apple also updated its base-model iPad with a new camera. The new iPad will start at $329 and the Mini at $499. Both will be available next week.
