Unless mobile and desktop have dramatically different code paths, we can possibly merge this with bug 1604029 now, which has a fix. Because 23% CPU on a desktop is likely the same thing as 100% on a phone.
If you assume both mobile and desktop share the same code then probably one of the following has to be true:
1. Bug 1604029 was a duplicate of this one and has solved it; or
2. This bug has gone away mysteriously.
