* Battery current is measured according to IEC 60118-0:1983/AMD1:1994 §7.11, IEC 60118-0:2015 §7.7 and ANSI
S3.22:2014 §6.13 after a settling time of minimum 3 minutes.
** Real usage battery life is shown as an estimated interval based on mixed use cases with variable amplification
settings and variable input levels, incl. direct stereo streaming from a TV (25% of the time) and streaming from
a mobile phone (6% of the time).
