Not  necessarily. Smartphones are renowned for their poor battery life and  will typically last up to around 24 hours. But the batteries of older  phones can last considerably longer. For  example, the Nokia 100 boasts a standby battery life of a staggering 35  days. Smartphone batteries can also last longer if the handset isn’t  being used, and especially if the phone is in Flight Mode. However,  if the phone is in Flight Mode, it switches off all wireless activity  meaning calls wouldn’t be able to connect, effectively ruling out this  theory.  If the phone batteries are dead, wouldn’t the call go straight to voicemail?In a word, yes. However, the process of sending the call to voicemail can differ depending on the service provider. For  example, the majority of phones will go straight to voicemail, or  callers will get an out of service message if voicemail hasn’t been set  up. This will occur even if the phone is underwater, or not near a cell signal. However,  some service providers will ring once or twice before the phone goes to  voicemail, or cut off. This may explain the reports that claimed phones  rang before seeming to hang up. Some reports claim the phones are just ringing and ringing though. How is this possible?Telecoms  expert Alan Spencer told MailOnline that if the phones are really  ringing, they can categorically not be under the sea. He  added that the phones will only be ringing if they are ‘switched on,  not in water, the battery is charged, and [they are] near a mobile cell  site.’This means that if  the phones are genuinely ringing, the plane needs to have landed on land  – not in the sea – and be in a location where there is cell service,  rather than landing in the middle of a jungle, for example. Why can’t network operators locate the phones?A number of family members have asked the network operators why they can’t use the phone’s signal to locate the missing people. Professor  William Webb, a Fellow of the Royal Academy of Engineering, told  MailOnline: ‘The phones definitely won't be working. They'll be  underwater, out of coverage and by this time out of battery. ‘So there's absolutely no way they could be used for triangulation. ‘As  to why they are ‘ringing’ it'll be the same as if they were out of  coverage - in some cases it may ring before going to voicemail.’What about the T3212 timer I’ve read about? The T3212 is a timer that causes a phone to periodically send a message to the network saying where it is. But  Professor Webb said this only works when the phone is turned on and it  is in coverage. It won't work when the battery is dead.What about reports that passengers are appearing online, on the QQ social network?When people sign into social networks including QQ, as well as Facebook, they appear online. This is the case whether they’ve signed in on a phone, tablet, PC, and laptop. if  missing passengers are shown as online, they may not be using the  service on their phone. Instead they may still be logged in on another  device. If this other  device shuts down or goes into standby, however, or there is a long  period of inactivity, the social network will log them out, which may  explain why some accounts went from online to offline over a period of  three days.</blockquote>
