even when switched to cellular off and not in use.
Because you have apps that use a lot of data, and from your description, do it as background processes. But without knowing how much is "so much" I don't think it's possible to answer.
ok when i say consuming data is that my iphone even with no social media apps and manualy almost everything... on my settings icloud off everything off ......last night my phone drained half my data plan when i was as sleep my phone seems use less cant turn on cellular data or it will eat my data
You've yet to define how much is "so much".
Do you actually want help? If so, try using actual English and answering the question asked. Otherwise you're just wasting everyone's time.
why is my iphone 5 consuming so much data?
