More than 70 percent of smartphone users in India switched brands in the second quarter of this year, befitting Chinese smartphone maker Xiaomi the most which sold nearly 37 percent of the phones that were replaced, according a CyberMedia Research (CMR) report on Wednesday.

Xiaomi was followed by Vivo (17.8 percent), Oppo (16.3 percent), Itel (6.7 percent) and Huawei's Honor (4.5 percent), according to the first edition of the CMR "India Smartphone Movement" report.

During the period, the fastest depleting brands in the category were Micromax (41.2 percent), Intex (11.6 percent), HTC (5.5 percent), Karbonn (5.3 percent) and Gionee (4.7 percent), the findings showed.

"Customer stickiness is the paramount concern that home grown brands need to address immediately," said Kanika Jain, manager, new initiatives, CMR.

"Consumers continue to swap their existing smartphones with the new ones offered by Chinese brands resulting in fast erosion of total installed base of the local Indian brands," she added.

Based on the analysis of over 200 million users across the country, the report further identified that the replacement market continues to grow in the country and in the second quarter of 2018, nearly 60 percent of the smartphones sold were actually upgrades/replacements of existing smartphones.

There is still 41 percent of new smartphone market development occurring in the country, which could be a pie that the domestic brands should focus upon, the report suggested.
