BEIJING — Consumers probably won't have to pay more for iPads, iPhones and other popular consumer electronics despite a Chinese company's pledge to trim work hours and raise wages for its hardscrabble assembly workers.

The paychecks already have been steadily growing even before this week's pledge, and labor expenses remain a small portion of the total bill for most gadgets made in China.

At most, the cumulative wage increases could crimp the profits of major technology companies. Manufacturers have a bigger worry in finding ways to save money on the parts that power the devices.

Nonetheless, assembly costs are likely to escalate because of Foxconn Technology Group, which assembles an estimated 40 percent of the world's electronics, including the hot-selling iPhone and iPad.

Foxconn, owned by Taiwan's Hon Hai Precision Industry Co., promised to limit hours while keeping total pay the same. That commitment will translate into higher hourly wages.

The pledge came after Apple Inc., the world's most valuable company, hired a labor auditor to review the practices and conditions in Chinese factories run by Foxconn. A report on the audit, released Thursday, evoked images of a sweatshop and said Foxconn routinely violated overtime laws by assigning its assembly-line workers to toil for more than 60 hours per week.

Foxconn has about 1.2 million workers and either currently or has assembled products for a host of technology companies.
