【贵手机就好用?山区旅游带款非智能机也是极好的】英国通信管理局委托的一项研究发现传统手机在智能手机打不出去电话,发不出去短信的低信号环境中使用依旧顺畅,原来智能手机对信号的要求平均是要比传统手机高7倍左右,出去旅游或出差,带款非智能手机或许用处还很大呢!

Old mobiles are better for calls and texts than smartphones: Expensive handsets found to not be as good at picking up weaker signals

  • Lab tests found modern smartphones not as good picking up weak signals 
  • Ofcom study found old phones better at sending texts than Apple, Samsung devices 
  • Smartphones needed signal seven times stronger than '2G' mobile phones
  • Findings back claims that glass, metal used in smartphones responsible for calls cutting off

Expensive and high-tech gadgets they may be - but new research has found today's smartphones simply do not work as well as the more basic mobile phones from a decade ago.

A study carried out by industry regulator Ofcom has found the no frills handsets of the past provide better signal performance for making calls and sending texts than modern smartphones sold by the likes of Apple and Samsung.

Tests conducted in laboratory conditions showed that despite being packed with technology, smartphones are not as good at picking up weak signals as cheaper devices.

The Ofcom research also found that some smartphones tested required a minimum signal which is 10 times stronger than what is required by non-smartphones currently on the market just to make or receive calls.

On average, the smartphones examined required a signal at least seven times stronger than the average non-smartphone on the 2G network.

The worst smartphone on the 3G network required a signal which is nine times stronger than the minimum level recommended by the GSMA, the standards body for the mobile industry.

On the 4G network, the worst performing smartphone required seven times the recommended signal strength to send data.

Ofcom's findings support claims that the glass and metal used in smartphones, as opposed to the plastic used in cheaper mobiles, are responsible for calls cutting off.

It also provides clear evidence of the role handsets play in signal coverage, alongside the investment in infrastructure which is required to improve coverage nationally, especially in rural areas where masts tend to be further apart and provide a weaker signal.

According to the research, which will be used to create detailed mobile coverage maps, even the hand you use to make a call can affect the chances of a call being cut off due to the position of the antenna and whether it is covered by the user's fingers.

Ofcom refused to identify the smartphones used in the research, claiming there was an insufficient number of phones tested to make signficant comparisons between individual smartphones.

A spokesman said: 'We tested a very small number of mobile phones, not for ranking but to understand how handsets performed in different situations.

'As no one device consistently outperformed the others we chose not to list the handsets.'
