Did you try check battery saving modes?

Hi MarcinP,
Yes, I did check battery saving modes. They weren't activated by default, and toggling them on and off didn't work. I flashed all three available updates (starting with the oldest, and moving through) 7 times in total with no change. Wi-Fi and bluetooth would work for 10 minutes or so, and then conk out. This is clearly a faulty Wireless chipset. I no longer have this device anymore, gone back to my Nexus 4 which is atleast stable and can handle bluetooth and Wi-Fi at the same time.

Sorry for your inconvenience.
Did you contact to seller?
Umi diamond has really strong and stable wi-fi, Bluetooth and GPS signal. Maybe your chip is faulty as you mentioned.
I hope that you will get proper solution for your device.
