"The phone a few minutes after finishing the benchmark. It no longer booted because the battery was too cold!"
Your time-average power budget for things that run on phones is about 0.5W (batteries are about 10Wh and should last at least a day). That's about three orders of magnitude lower than a the GPUs running in datacenters.
Even if battery technology improves you can't have a phone running hot, so there are strong physical limits on the total power budget.
More or less the same applies to laptops, although there you get maybe an additional order of magnitude.
