Thank God for the EU (& the UK) for forcing OEMs to truthfully report their mobile device performance (including the UK's battery life requirements).

As of June 20, 2025, all OEMs selling mobile devices in the EU have to
formally report standard benchmarks where all the OEMs used the same
official testing 3rd parties & where all the OEMs knew the standards years ahead of time, such that EPREL is a wealth of benchmark data where all the tests were run similarly on all devices.

IMHO, the EPREL is truly the Holy Grail of benchmarks.
(too bad no USA-specific models were included)

Google Battery Endurance Summary
Original decimal average:
Total = 241.85 hours, Average over 5 models = 48.37 hours

Rounded to nearest whole hour (Apple-style):
Values: 49, 51, 40, 50, 52 ? Total = 242 ? Average = 48.4 hours

Truncated to whole hour (Apple-style):
Values: 49, 50, 40, 49, 52 ? Total = 240 ? Average = 48.0 hours

Total hours = 1,199.0
Average = 1,199.0 / 19 = 63.1 hours

Note: It makes no difference if you re-calculate all the numbers
Apple-style, which is a truncation apparently, as I ran all the numbers
three ways, namely as is, by rounding, and by truncation. Hence, Apple's (clever) marketing spin that they reported numbers "lower" than they could
have is meaningless and, worse (much worse) Apple's (brilliant) truncation
cast untoward aspersions on the entire formal process that every OEM,
including Apple, had themselves already long ago been part of.

Overall, Samsung models, based on EPREL data, have a 10 hour advantage.
That's a whopping ~16% higher average battery endurance per cycle.
However, Apple had a decided advantage over Google mobile devices.

I'll send a separate post with a breakdown by smartphones vs tablets. Especially as Google doesn't have tablets to bring the averages up.

And I'll show the proof that it doesn't matter how you round or truncate
the numbers - they still end up being the same within minor differences.
