You can try to disable git in Source Control if you dont use it all the time. Sometimes enabled git plug-in can increase your CPU usage. To disable git plugin go this way:
Tools -> Options -> Source Control -> and than set Current source control plug-in to None
(I hope this was helpful for you, if it was propose it as an answer.)

Thanks for Almir Vuk's reply.
Which Visual Studio 2015 version are you using? If run Visual Studio without any solution, just open it, does it have this problem?
Please try Almir Vuk's suggestion first to make sure whether this problem is caused by the source control you are using.
Visual Studio CPU high usage is a common problem, it can be caused by different reason. Create a new project to check ,whether it occurs with just a specific project or all type project.
If for a specific project, please try with following steps to troubleshoot this problem.
- Run your solution in another computer, if it has the same problem, it related to your solution. If works fine in another computer, it related to your Visual Studio.
- Please confirm all files opened by Visual Studio in your project is included in project. If not, please right-click to Include it into project.
- Please close all designer editor in Visual Studio, such as XAML designer, which will consume some CPU and Memory to render the interface.
- Delete the .suo file in solution folder, which saves user settings for current solution.
- Create a new blank project and the remove the files one by one to confirm which file causes this problem.
If for all type project, please try with below steps.
- Run Visual Studio 2015 as Administrator.
- Run Visual Studio in safe mode with "Deven.exe /SafeMode" to prevents all third-party VSPackages from loading when Visual Studio starts, thus ensuring stable execution.
- Uncheck "Automatically adjust visual experience based on client performance", "Enable rich client visual experience" and "Use hardware graphics acceleration if available" option in Tools -> Options -> Environment tab.
- Disable the diagnostic tools under TOOLS->Options->Debugging->General.
does the high cpu usage lower after some time (some minutes)? That's the issue here. when working with solutions the cpu usage will be high with an incredible slowdown of intellisense for about 5 or more Minutes. Then things are going somewhat better.

No, it does not lower. It goes up as soon as a solution is opened and stays. Also very often after closing VS devenv.exe is not disappearing from the Task Manager.
hm, not an issue here. The only things that are kept a while in task manager are those VS-Hub things, some compilers and the conhost stuff...
HI all, Same thing with Visual Studio 2015 Professional, and sometimes when i close VS launches an error "Visual Studio has a unexpected Error", then i must close it by Task Manager.
Adding some information, i working with TFS and ASP.NET MVC with EF, so i cannot turn off the source control. It's a very buggy version of Visual Studio.
