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.

I'm a scientist and an engineer so I especially delve into benchmarks.
In this case, we need to separate the smartphones from the tablets.
Because they're inherently different in that tablets have better batteries.

Brand Comparison (All using Apple-style truncated values):
Samsung Average endurance 73.07 hours (from 28 models)
Apple Average endurance 63.1 hours (from 19 models)
Google Average endurance 48.0 hours (from 5 models)

Breakdown by tablets versus smartphones in the EPREL database:
Apple 16 smartphones, 3 tablets
Samsung 22 smartphones, 6 tablets
Google 5 smartphones, 0 tablets

Quick summary of the math.
Apple smartphones:
Values = 62, 72, 67, 72, 67, 62, 41, 67, 67, 37, 48, 48, 37, 34, 45, 40
Total = 1,070h, Average = 66.9 hours

Apple Tablets:
Values = 73, 73, 77
Total = 223h, Average = 74.3 hours

Samsung Smartphones:
Models with typical identifiers (e.g. SM-A, SM-G, SM-S):
Values = 40, 38, 37, 45, 41, 43, 44, 45, 44, 43, 42, 41, 41, 44,
38, 43, 44, 37, 41, 42, 41, 41
Total = 906h, Average = 41.2 hours

Samsung Tablets:
Models starting with SM-X:
Values = 98, 55, 142, 142, 96, 99
Total = 632h, Average = 105.3 hours

Google Smartphones only (no tablets):
Values = 49, 50, 40, 49, 52
Total = 240h, Average = 48.0 hours

Summary of averages by brand & type:
Smartphones Apple 66.9h Samsung 41.2h Google 48.0h
Tablets Apple 74.3h Samsung 105.3h Google (none)

Looking at tablets only, Samsung dominates with especially high endurance numbers over Apple (Google doesn't seem to have tablets sold in the EU).

Looking at smartphones, Apple shows a clear lead over both Samsung and
Google in terms of benchmarked battery endurance cycle performance metrics.
