Suddenly space full?

I have a Huawei, my battery goes first very fast down he does not even hold a day and that happened quite suddenly without explanation now is also the memory full but I have counted the numbers together and that just does not fit together that also happened

once i had nothing else special on my cellphone just the usual.

Does anyone know? Or is that the case with someone? An explanation would be nice

Clean up on your phone, you have to do it regularly. D. H. Keep pictures, apps and co only if you really need them, otherwise down. With that you should get rid of 5GB

Save data and run it once

I do that regularly and I also deleted some apps but did not do much
