Across the country, people are waiting longer before upgrading and, when they do, are increasingly choosing something other than an iPhone.

Ironically, it's not the iPhone X that's helping Apple out here, but sales of older, cheaper iPhones at the carriers instead.

Smartphone sales revenue grew to their highest levels ever according to Strategy Analytics. Apple, Samsung and Huawei all grew share.

Huawei managed to handily beat OPPO for China's Q4 2017 and full-year smartphone crowns, with Apple in fifth place overall, but easily the champion of profits.

Apple's iPhone X ruled the October - December 2018 charts in Urban China, according to the latest Kantar Worldpanel ComTech data, also selling very well in Europe, Japan, Australia and the US.

Samsung may have been India's top overall 2017 smartphone vendor, but Xiaomi won the final quarter, also leading the full-year model popularity chart.

Global smartphone sales only achieved minor growth during Q4 2017, according to GfK market research, but average smartphone prices surged at a remarkable pace.

Xiaomi may have surpassed Samsung in Q4 2017 smartphone shipments in India, but the world's number one mobile device vendor was also the region's champ in actual sales to customers.

India's extremely important smartphone market was dominated by Xiaomi rather than Samsung during the final quarter of last year, while Reliance Jio won the local feature phone trophy.

The iPhone X wasn't Apple's best-sold mobile device between October and December 2017 in the US, according to the latest CIRP report.

Apple is number one in CIRP's Q4 2017 US smartphone activation rankings, surging from a 34 percent share during the final three months of 2016 to an impressive 39 percent.

Apple was one of China's top performers in overall 2017 smartphone sales volume, with the iPhone 7 Plus ranked second and iPhone 7 fifth on the best-selling model list.

Ahead of a somewhat surprising December demand slowdown, Apple's iPhone X reportedly crushed the competition in the month of November, at least across three major global markets.

Samsung should continue to dominate the global smartphone market next year, but Apple and Huawei are expected to start narrowing the gap.

The August - October 2017 timeframe wasn't particularly fruitful for Apple in global smartphone sales, as the iPhone X launched in early November.

Meanwhile, the Surface Pro (2017) is getting adopted at a nice clip while the Surface Laptop is just starting to creak through the floorboards.

The majority of iDevice users are already on iOS 11, but the latest platform version isn't spreading anywhere near as fast as iOS 10 and 9.

First weekend market share for the iPhone X is right up there with the iPhone 7, iPhone 6s and iPhone 5s. Nowhere near the iPhone 6, though.

There's no recovery in sight for worldwide tablet shipments, based on IDC's latest research, even though the leading OEMs aren't doing so bad.

Samsung dominated global smartphone shipments again during Q3 2017, followed by Apple, Huawei, OPPO and star performer Xiaomi.

Huawei remains the king of smartphone shipments in its China homeland, according to fresh market research, narrowly beating OPPO and Vivo again.

According to the latest Kantar Worldpanel research, Samsung dominated June - August 2017 smartphone sales in the UK, while Apple reported strong US growth.

The newest Android distribution chart is the first to include 8.0 Oreo, at just 0.2 percent share, with Nougat gaining 2 percent over the past 30 days.
