I have Sony Xperia M.The battery is BA900 and on battery say that minimum voltage is 3.7V but around 6-7% it's drop to 3.5V.I only want to know is that normal.
What do you mean by 3.7v - is that the charging power or output to make the phone run and if it's the latter then the power may drop if Eco mode is enabled aka Stamina mode
ok so 3.7v is the discharge power however it also has a nominal power discharge of between 3.3 and 3.7v and when fully charged the discharge power rate is 4.2v but can rise to 4.35v so your 3.5v reading is within tolerance or the nominal bracket
