Well depends, Apple has been refining their arm chips for many generations now. Generally the Arm competition (non-apple) hasn't caught up to Apple yet. CPUs are amazingly complicated. A major new CPU designs can take 3-5 year, consume many $100M, and end up not competitive. Even Intel has had serious issues after many years dominating their market. The ecosystem of OS kernels, platforms, testing/verification tools, compilers, debuggers, and related can take awhile to mature. Android is a major platform for phones, and while by default apps are portable, assuming the vm is ported, but some apps write native code to avoid the Java related overhead. Intel tried a phone and ended up emulating ARM chips for native arm code and delivered terrible performance and terrible perf/watt. That project died with a total design win of (I believe) just a single relatively low volume phone. So making a CPU to compete with a flagship android phone isn't easy, and even if investing some multiple of $100M and years you might end up still behind, or bankrupt when you scare Arm into cutting prices again.
