    I seem to have been getting particularly poor performance from the battery on my PSP recently.
    A full charge doesen't last as long as it used to...


    Looking at the battery, it's marked mAh (Nickel Hydride) I do recall mAh batteries having a problem with shrinking capacity ....


    Anybody else in the same boat??

    Most (not all, but most) rechargeable batteries deteriorate if you charge them before the battery empties. If you read directions on most rechargeable batteries, they usually state that you should let the power completely drain out of the battery before fully charging it again, or the lifespan will keep shortening.

    Battery power on the psp also varies on some games and depending on what you are doing. Gta drain bateries faster than most other games

    The problem I seem to have with my PSP is i'll fully charge it, play a game for maybe 30 min to an hour, turn it off (and it is fully off not in "standby") then not touch the thing for another 2 weeks. When I come back to play and the battery has somehow drained completely because it won't power up. I do the same thing with my DS and never seem to have this problem.

    That slipped my mind, could have been a while since i remembered to let it run flat to the point of switching off.

    Thanks for the reminder.

    Yeah. I've noticed this on mine too. I know that the battery does deteriorate, but I think the main reason is that maybe newer games have been using more power than the ones at launch.

    Also the reason, when you leave it for a week and losses its charge. Is due to the unit keeping the date and time right. That does not take much battery power, but if you leave it long enough it can drain a battery.

    Weird. I plug mine in to keep the charge up all the time. If I'm not using it at home, it's plugged in. I haven't ever really drained the battery all the way. Closest I ever got was down to about 12% battery life and mine still maxes out at the same as it did the first day I started using it.

    The problem isn't it not maxing it out - the problem is the cells thinking it's empty when it's really not.

    If you always charge it when it hits 50%, then eventually the batteries will treat 50% like it's really 0%, affecting how long each charge lasts.

    PSP uses a Lithium-ion battery.
