My q10 sometimes resetting, doubletyping, battery problems

First, sorry for poor english.

I have Q10.. but I cant use my phone..

Because:

Sometimes; when I try swipe screen for unlocking phone, my phone is restarting.. sometimes resetting 4-5 times on loading screen..again and again.. sometimes restarting again if I touch screen again.

If the weather a bit cold (6-14degree is lowest weather in my city) when I out of my pocket to call someone, phone says instantly "battery low" and closing. When I try to open my phone again, says battery is empty. (but more than %90) I can only use my phone inside if the weather is lower than 15degree..

Sometimes my keyboard double typing.

I sent guarantee for 4 times. They always only reinstalling OS.. and sending my phone back.. they sux.

How can I do for my issues? U have that too?

The first thing I would say is the doubly typing issue I thought was a hardware issue. SO I think they need to replace your device. But let's look at your OS. Which one do you have? And how much do you have running on your phone at one time that it needs to reboot. Usually that only happens with rogue apps or too little memory....

10.2.1.2977 my version..

I downloaded : whatsapp, evernote, bodybuddy and skype..
