Just pop some question about battery using.
1. If I switch to sleep mode, is it waste any battery power there? How long the sleep mode can be? 1 hour? 1 day ??? Sometime playing game suddently phone coming or anything happen need to stop quite long time, but the game is going half way already...
2. If turn the sound loud will waste more battery power ??? I turn my psp sound just 1 block only and i can heard it but if i slot in the earphone maybe need use 5~7 block then only heard.
1. Sleep mode doesn't really consume battery power. Just go to sleep mode for your convenience. I have once gone on full charge and played for a moment only and put it on sleep, then without realizing it, left it in that mode for like a a good 8 to 9 days because I was away and when I came back, i turned on the PSP only to realize it was on sleep mode, and the battery indicater was on half bar.
So yeah i guess go on sleep mode cause it only consume very very minimal power, almost negligible, so no worries for convenience.
2. Turning up the sound doesn't really consume much power so don't worry. Just make sure you don't blow your PSP speakers.
Should you know, the only part which consumes A LOT OF POWER is playing:
a) heavy graphical games or watching videos
b) putting the brightness level at highest level (at lvl 4). You should, if possible, play at the lowest level setting to reserve battery. However, under bright conditions, like open air area, you have no choice but to bump the brightness up so play in a closed area if and when possible.
