yesterday morning i charged the battery fully - i think if it is not fully charged there is some kind of red light, and when it is fully charged it turns to green.
the battery symbol also showed a full green.
so after the full charge, i listened to like an hour or so of music.
and then again for another hour or so i listened to music.
before i went to sleep, the battery symbol showed atleast half full.
but in the morning it was totally empty.
i simply press the one button one small instant and the screen winks out. and the screen doesn't respond to touch unless i press the on button again.
this is not shutting the phone off - but a kind of semi sleep mode i think. and this is what i did before i went to sleep.
but i was surprised that it exhausted the battery during this sleep mode.
am i supposed to shut the phone down to preserve the battery charge?
appreciate the feedback.
