I never saw VS consuming CPU cycles just by being started, if I do not request it to perform some operation.
Plain editing (with IntelliSense support and immediate marking of syntax errors) is barely noticable on the CPU load. If I start the program I am developing to run under control of VS, there is of course some CPU load even when the program is at a breakpoint or waiting for input, with no active threads. This is to be expeced: VS monitors e.g. the heap and GC continously. But this is at such a level that I never though of it - nowhere close to 20%.
If you have threads running under the debugger, and these are in some active state, you must expect the CPU load to be somewhat higher than if you run the executable standalone, especially if you set a lot of conditional breakpoints, and those threads hit the breakpoint without satisfying the condition. Other debugging functions, like monitoring memory use etc., are also bound to take some resources.
So I cannot agree with your statement.

I see you're not familiar with ReSharper...

The only reason I do not use ReSharper is that it slows my PC down so much. I only have an old Phenom II x4 965 and no SSD, so it is quite noticeable. I'll start using it when I upgrade to an SSD.

That was my point. No matter how fast a system is, ReSharper will find a way to make it feel sluggish.

Yes, I know that resharper slows down VS. but the project I came into has 190 c#\wpf sub projects. Very slow loading and compiling. It has evolved to get this large and no time to redesign it right.

I've seen this same issue with Arduino studio (it's written in Java) and I have to shut down the IDE all the time or the fans will run on my PC as the CPU usage goes way up.
Maybe Android Studio was checking for SDK updates or other types of updates. Or maybe Gradle (build system) is running in background?
Maybe it was still doing some background updating since you just installed it? Is it keeping high CPU now?
I haven't seen Android Studio be that bad and I do quite a bit of Android development. Every revision of Android Studio does get a bit more bloated however.
I Opened Android Studio and Watched Task Manager
I have the latest version Android Studio and I fired it up and it is sitting on the splash / open a project screen at about 0.8%. Then I opened a project and let it sit and it's at 0% while I'm doing nothing in it.

It was a background worker (I left it run overnight to finish) that installed a local copy of Gradle, even I have the latest already installed on shared location... After finishing it, it came to peace with the computer...
Wondering why the shared Gradle didn't satisfied it, maybe that I installed it under /opt...

Interesting. It is a bit disconcerting that it does this stuff in the background but doesn't even let you know so we see the behavior and can't really tell what is happening. It's not very helpful of the devs to not just give a warning that the background thing is running. Glad you discovered what it was.

"Speaking of Java"? who did this? wasn't me! 
Android studio only use 20% of your CPU? You must have one of those 100 cores new Xentreon ultimate CPU, don't you, hey?!

I'm guessing it is the IntelliJ-based Android Studio we're talking about. IntelliJ is notorious for its long indexing times :P
The JVM is - in my experience, at least - not too CPU-intensive, it is mostly the RAM that gets used up quick (or at least with the ConcMarkSweep GC; in Java 8, the G1 seems to do better: -XX:+UseG1GC)

I find it both ironic and humorous that you can't install that app on your Kindle Fire.

It's even more funny/ironic considering the name of the app/mug is Ember!

Iiiiigit, why not invest in a Espresso machine. Heat up in between something around 20 seconds and get a more or less fresh Cup of coffee?
Sorry  and all the best 
It does not solve my Problem, but it answers my question

so you make your coffee, and realise you forgot to charge the cup.
...anyway I'd never take that long to drink a cup of coffee, unless I fall asleep half way through (which does happen once in a while and no, it's never decaf), in which case I make a fresh one.
(In fact anything over 10 mins (very rare) is pour out and make another, I can't abide stale coffee.)

Hmmmm,
According to the TIOBE Index the self-heating java mug is the most popular programming utility of 2018.
JAVA MUG
The Visual Basic mug was the second most popular and the C# mug came in third-place this year. Unfortunately the C++ mug came in last place again signaling the decline of this once popular programming utility.
Best Wishes,

I thought about getting one of these for my wife to keep her tea warm due to this thread. I found it on Amazon and everything looks great until you read the reviews. Three things keep popping up. Delamination occurs after a few weeks, the springs in the charger contacts fail causing the charger to no longer work, and the app is buggy causing it not to work on Android devices.

Same thing when you are stupid.

If the app won't install on your tablet, then just get any random app that keeps the CPU busy. Then flip the tablet over, and place the mug on top of the spot where the CPU is.
(not entirely joking...)

Err...because they want to support phones that most people use? And ones that people will be using in the future?
Realistically though it probably supports whatever devices the single developer working on the project already knew. Or at least I am hoping it didn't take a team of 100 developers to make that app.

I'm not getting it: Why do you need to keep the mug warm for 2 h 20 minutes, after you have emptied it?
|

That was my first thought.

But what about those times when you have a problem piece of code? The normal solution is to wander over and get another coffee, by the time you get back you can see the answer. This mug sounds counterproductive to me.

Well it is on the small side, so more trips to the coffee pot, but less waiting on the microwave. If it's a tough problem, I go out to the woodshed.
