Crimes like burglaries needing to view the IP's phone. If the suspect brings up a defence which requires you to examine it. Otherwise you're looking at failing to investigate.
A few examples - Suspect is alleged to have entered his ex-partners house and removed items. Victim states that they had split up months ago, have had no contact with each other and there is nothing now in the house which is his. His defence is that there are lots of items in the house which are his and had been agreed to remain there whilst he sorts another flat out. There have been numerous messages from the victim to the suspect which have become angry and are now threatening to sell/destroy his things. He turns up to get them and uses a key to enter.
Suspect is found in the garage by the family of the victim. Victim states that she doesn't know who he is and has no lawful reason to be there. Suspect's defence is that they have been having a relationship for many months and messages on the victims phone will show that. He has no access to a phone and has been using his friends to contact her.
No lawful reason for fingerprints of the suspect to be found on the outside windows of a property. Victim states they have no idea who this person is. Suspect raises a defence that he is their window cleaner and sent them a message from his friends phone to say he was coming over that day.
Teacher has an inappropriate relationship with one of her pupils and promises gifts in exchange. She reneges on this and so the pupil takes the items from her house which she promises him. She reports the burglary and denies any form of relationship between them. Pupil is arrested but has deleted any phone messages of his phone in case his parents see them. He does state that she might have messages on her phone inviting him round and will show the time frame of their relationship and what she was doing.
Its not the case that 90% discontinue the case. We don't leave victim's high and dry without a phone and provide them with another if we need to take theirs. Its not very often in any cases that we take the victim's phone. The vast majority of sexual offences I deal with I haven't taken the phones of the victim.
Length of time it takes to hold the phone - we can't give a definite time as other cases come in which jostle the queue around (high risk missing from homes for example will take priority as its an ongoing incident). Should we employ more officers to work behind the scenes on phone down loads? I would say yes, as it will speed things up - but most of the public want more officers on the streets and not behind desks.

You never gave a response to this one. If you don't trust the police what do you want us to do here?
So if you are accused of a crime, arrested and interviewed - and in your interview you state that there is messages on the victims phone which would exonerate you. How would you want the police to act?
Would it be ok to state that we are not allowed to look into the victim's phone records, so you're going to be charged & convicted of the crime? Or the victim will not allow us access to their phone so you're going to be charged & convicted?
Or do you want the police to look at all lines of enquiry for an impartial investigation?

It has to be specific to the crime and subject to a RIPA application. These applications are heavily scrutinised for proportionality, necessity and collateral intrusion - and often get kicked back to us for adjustments.
If its relevant to the case, then yes it will be examined to show any relationship before the offence - phone traffic, GPS, cell site data, who its attributed to etc etc. Also, if on the basis of an application other offences are seen, they will be investigated to.
For example - if we are looking for harassing messages which show a course of conduct and on looking at these messages, they start to fall into malicious communications, then these will be exhibited for that offence.
Much the same as screen savers or backgrounds of phones which commit offences. We might not be looking for images, but if the image is there as soon as the phone is turned on and its illegal, we can't simply ignore it.
