retained in the UK, except by Three. Records do not correspond to packets or tcp sessions, they correspond to 'an entire connectivity session' (I'm not familiar enough of mobile phone protocols to identify that) which are apparently 'closed' due to, for example a time out, which can happen after 5 minutes of inactivity. So it is plausible that a poll every 10 minutes by an email client could cause a comprehensive location record for a UK user, as in the Spitze case. But I don't have evidence of whether this typical.
