Apple’s new iPhone 4S, which debuted with millions of sales, may have issues with battery life, according to a report in the Guardian.
The news site reports Apple engineers are fielding inquiries about a reduction in battery life compared with earlier models of the smartphone.
Apple had already warned that stand-by time for the iPhone 4S would only be 200 hours, compared with 300 for the iPhone 4, but said talk time in 3G would be as long or longer.
Users, however, are complaining battery life has been much shorter, even with minimal use and shutting off features that normally would sap battery life, like location services.
The Guardian said Apple engineers was reaching out to some iPhone users to collect information in an effort to track down the problem.
Apple is expanding sales of the phones to 22 more countries this weekend after launching it two weeks ago in the U.S., Canada and the United Kingdom.
Separately, it also looks like Samsung may be eating some of Apple’s smartphone lunch.
