Samsung wireless charging jaedojeon ... 'Galaxy S4', Chi (Qi) way mount

Give resonant magnetic induction method ... way to switch the magnetic induction

[Digital Daily reporter yunsangho] Samsung Electronics 'Galaxy S3' wireless charging nemesis 'Galaxy S4' to put back. Change the resonant magnetic induction magnetic induction. Standard protocols that are not resonant magnetic induction, rather than the way the 'Chi (Qi) to commercialization for certification issued a self-guided side because.

Samsung Electronics, according to industry on the 17th next strategy, smart phones Galaxy S4 provides wireless charging capabilities. Wireless receiving terminal was built at the rear of the unit. The wireless charging receiving coil is placed in the rear case. Samsung wireless charger wireless charging receiving coil case and is scheduled to be sold separately through Annie mode.

Galaxy S4 wireless charging approach is self-guided. WPC (Wireless Power Consortium) standard specifies. Attach the device authentication. The compatibility between the certified product. Since 2011 have been full-scale commercialization.

Wireless resonant magnetic induction and magnetic induction charging method receives attention. Commercialization speed, charging the handset and charger is fast, but you need to contact The downside is that the self-guided. Resonant magnetic induction method, the distance at reduced handset and charger can be charged, but the slow speed commercialization.

Way wireless resonant magnetic induction charging Samsung Galaxy S3 to gauge initial seeking to nurture. Resonant magnetic induction method charging the charger and handset 1 ~ 2m apart. However, a distance of as much as a waste of power and to minimize the effects of surrounding is key. Galaxy S3 battery mounted on the antenna for short-range wireless communications (NFC), the wireless receiving terminal on the back of the product had posted. Galaxy S4 NFC antenna on the battery.

Industry standards, as well as the resonant magnetic induction undetermined safety standards for power efficiency is not easy to get to point that Samsung felt that the burden was analyzed. Resonant magnetic induction, Qualcomm, Apple Sony also collect patents but never to come up with a commercial product. Samsung Galaxy S3 resonant magnetic induction charger did not commercialize the way. Were limited way wireless magnetic induction charging Galaxy S3 to be released in some areas. Eventually have parts cost waste product mounted on a wireless charging terminals.

Official Samsung charger "resonant magnetic induction approach commercialization, but the development was not considered appropriate," he said, "tentative" self-guided wireless charging battery cover and charger sold.

On the other hand, self-guided, ahead of Samsung Electronics, LG Electronics smartphone preloaded. LG Electronics Optimus LTE2 'and' 2 'Optimus view, built-in magnetic induction charging coil way. Made with LG Electronics and Google 'Nexus' wireless charging support this approach.
