New 'SpareOne' mobile phonehas a battery that lasts for 15 years

[NorthernRaider]

I just made sure all our families mobile phones are from the same manufacturer and thus use the same battery, but the primary weakness with the mobile phone network is
(A) Its limited coverage, most very romte areas have no coverage
(B) The vulnerability of the indivifdual towers and tower clusters, if the power goes off for any reason huge areas are without a service
