Sony mz RH1 battery & R900
The RH1 battery I'm using is shortened to about 5 hours, so I bought two new NH-14WMs... What's the reason why the usage time is not long at 6~7 hours?
But R900 xan use more then 10hours.
EQ always on, volum 15, OLED all ways scroll condition. Cause of CFW setting problem?
