BlackBerry Z10, so many frustrating issues

Question

I have been using my Blackberry Z10 for 4 months.  I still have so many issues that don't work like I would like, and I know if there is something that can fix them.  There is a list, for sure there are more that I don't remember right now. 
Battery: it never arrives to low charge before turning off.  Close to 35-30% it goes to sleep.  I tried some of the solutions I´ve read (full charge after taking out battery, reset, etc) but nothing worked.
Two times blocked: Since last OS update, I unlock the phone with my key and some seconds later another screen asks me to put the key again.  It doesn't happen always, but very frequently.
GPS and tracking: I downloaded every app for tracking gps, like Endomondo, Runkeeper, etc, and no one works.  It is always "searching for satellites".  Sometimes, in an hour, it gets the satellites for e few seconds.  I downloaded GPS Status, as mentioned in other forums, and it works.  But not the other apps.
Transferring files: When I connect it to the computer and want to transfer files from internal memory or the microSD card, it looses connectivity while transferring.  I have to move files to the SDcard, then take it out and transfer them in the SDcard reader in the computer.
Music stops while playing: very frequently music makes very little pauses during the play.  I hate that when I play music.  I kill all the tasks, so the only thing running is the Music, but it is not solved.
Wrong words learned: when you make a mistake and type wrongly a word, it remembers it and suggest it up to the end.  For example: it seems I once wrote "Germn" instead of  "Germán".  So I type G+e and it suggest me "Germn", then I type the r, and continues suggesting "Germn".  I hate that.
Automatic message in the mail account: I must turn off the Automatic message "Sent from my smartphone..." every few hours.  It goes back to on and put that message again...
Any idea of possible solutions?
Thanks,
Martín

If you had one or two issues, I'd suggest tackling them individually but because you're experiencing issues at this level, your OS should be looked at.
What OS are you currently running? To find this out, swipe down and select Settings>(Category - OS) and give us the OS version.
