   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)

     Rounded to nearest whole hour (Apple-style):

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

     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 all about facts where I generally don't believe marketing benchmarks.
