We see from your search that you're looking for information on the term "Mobile phone manufacturers",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Charger chips meet USB battery specs from
NXP Semiconductors, which we summarised at the time by saying "Devices can detect and differentiate between a dedicated USB charger, USB host charger and USB host when charging a mobile phone battery".
A few weeks before,
we featured the news release Wireless communication tester has China covered from
Yokogawa Europe - Test and Measurement: "Test software option supports the TD-SCDMA third generation mobile telecommunications system now being considered for commercialisation in China".
In October 2007, we covered the news from Advanced Analogic Technologies
concerning its AAT1270
- take a look at Power chip enables brighter flashes
which says: "Step-up current regulator delivers the high current levels needed to support flash lighting for higher resolution CCD imagers".
Take a look also at the news release from Agilent Technologies Europe, Software supports multiformat handset calibration,
as well as MSc is devoted to mobile applications development from London Metropolitan University,
and Software production management addresses Symbian from Electric Cloud.
