IPhone system taking up 37gb on mum 64gb phone, how to reduce?

MY NOT MUM***********

Dump the iPhone system, install Android.

  • Will i reduce my iphone's battery life? If i never turn my iphone 4s off and only put it on sleep even throughout the night when it is charging forever and never turn it off, will it eventually make the battery not last as long? What about on my macbook pro?
  • IPhone 6s system taking up too much storage? I have an iPhone 6s. Had it about a year. Recently I ran out of storage, I checked my settings and it says the "system" is taking up most of it. I read some articles that said to update it to newest update, factory reset it(as a new phone), and I've done everything. Right after I factory reset it, I checked the storage and nothing changed with the system. Can anyone help? It's taking up 5.43 GB out of 16 GB. I really want to keep my current phone!
  • IPhone 6S 64gb or iPhone 6 Plus 64Gb? IPhone 6S 64gb or iPhone 6 Plus 64Gb. I already have a 6 but I really need the storage. Should I order a 6S or get 6 plus instead?
  • I lost £50 that I took out of the bank for my mum She s going to be really angry with me and I don't know what to do. I previously lost my iPhone 6 and she was so mad at me so I literally have no idea what to do. I only have £10 out of my savings and she s going to realize sooner or later. How can I get £40 really quickly.
