ComScore
figures show that Android had second slow month in a row while Apple
added 3.2m users - but BlackBerry and Windows Phone now have struggle
for third place.
The
number of new Android users was the smallest added since April 2012,
when only 0.3m new users were added. Android's share of the market
dipped for the second successive month to 52.3%, from the peak of
53.7% in November 2012.
But
the figures still give Android the largest share of the smartphone
market, which has now reached 129.4m users in the US - 55.3% of the
234 million people aged over 13 with phones by ComScore's figures.
The
data are collected from "an intelligent online survey of a
nationally representative sample of mobile subscribers age 13 and
older." It only counts primary mobile phones, and doesn't
include second phones provided by employers.
According
to the data, there were 67.7m Android users in January 2013 -
compared to 49.2m at the start of 2012, a gain of 18.5m. Apple's
iPhone, meanwhile, grew from 29.9m to 48.9m, an increase of 19m.
Together,
Android and iOS have 90.1% of the US smartphone market.
That
leaves BlackBerry and Windows Phone fighting it
out for the third place spot. BlackBerry still leads with 7.6m
handsets in use, against 4m for Windows Phone. But while BlackBerry
has lost 7.8m users in the past year, Microsoft has not so far been
able to benefit - with its total number of handsets running Windows
Mobile or Windows Phone actually dropping by 0.5m in the same period,
even though the total number of smartphone users has grown by 28.1m.
Samsung is
the second largest smartphone supplier in the US, ComScore said, with
a 21.4% share, equivalent to 27.7m users. With few, if any, users of
its Bada system in the US, that means that Samsung has 41% of the
Android market - slightly lower than its worldwide share, which is
closer to 50%.
After
that comes HTC, with a 9.7% share of the overall smartphone installed
base. Its position in the US reflects the struggles it has been
having more broadly: on Wednesday it announced that its revenues in
February fell by 44% year-on-year. In the US, the ComScore data shows
that HTC's user base has fallen from a peak of 15m in January 2012 to
12.6m a year later.
Google-owned
Motorola had an 8.6% share, down from 10.0% three months earlier.
Like HTC, Motorola's installed base has been falling steadily, both
in smartphones and featurephones; as recently as March 2010
it was the most-used brand in the US.
LG
was the fifth-ranked smartphone brand, with 7.0%, equivalent to 9.1m
users. That has risen from 8.1m in October 2012. It's unclear whether
the increase is reflected by sales of the LG-made Nexus 4 phone -
which is branded as a Google phone rather than LG.
