The third quarter got off to a rough start for Apple’s iPhone, but the iPhone 7 was able to save the period in just two weeks, according to new data.

The iPhone 7 and iPhone 7 Plus combined accounted for 43% of total iPhone sales in the U.S. last quarter, despite only being available for two weeks during the period, Consumer Intelligence Research Partners (CIRP) said on Thursday. The iPhone 7 accounted for 31% of total iPhone sales, compared to 12% for the iPhone 7 Plus, the research firm says. CIRP didn’t share unit sales.

The iPhone 7 line came along at the right time. CIRP said in a statement that the iPhone was experiencing a “slow quarter” in the U.S. before the iPhone 7 arrived. However, the research firm believes the slow quarter was due to prospective customers anticipating a new iPhone launch rather than any concerns they had with buying older iPhones like the iPhone 6s.

Apple AAPL released the iPhone 7 on September 16. The smartphone comes with a similar design to last year’s iPhone 6s, but features a more powerful processor, brighter display, and a Home Button that responds to inputs with a vibration. Apple also eliminated the headphone jack in the iPhone 7, making it the first smartphone from the company to lose the prominent feature.

Early reaction to the iPhone 7’s headphone jack omission was mixed, causing some market researchers to question how popular the smartphone might eventually be. The data from CIRP, however, suggests customers weren’t nearly as concerned about the iPhone 7 as some analysts had predicted.

That said, CIRP’s data suggests Apple’s iPhone 7 has done little to sway Android users to the smartphone.

“The new 7 and 7 Plus models attracted mostly loyal iPhone owners, rather than Android owners,” CIRP partner and co-founder Mike Levin said in a statement. “Only 9% of 7 and 7 Plus buyers had an Android phone, while for older iPhone models, many more buyers, around 20%, came from Android. In contrast, at this time last year, when Apple launched the 6S and 6S Plus models, 17% of buyers who bought the then-new 6S and 6S Plus came from the Android operating system.”

CIRP’s data is based on a survey of 500 U.S.-based Apple customers conducted between September 25 and October 10. Apple hasn’t yet announced worldwide iPhone 7 sales, but could shed some light on how popular the smartphone is on Tuesday when it announces its fourth-quarter earnings.
