Hardware Battery drains when off

[Ozito]

Did a search but came up with nothing relevant.

As the title says, the battery in my psv drains when having it completely off and not in standby.
Anyone with the same problem, is there a solution?

Battery self discharges, meaning they lose power even when unused. Rechargable battery has higher self-discharge rate than non-rechargable.

How fast does the battery drain?

That's weird.
Try charging it to max and leaving it off.

Unfortunately i haven't kept track of the amount of days it takes to discharge.
I charged it overnight now after I started the thread, I'll keep it off and see how long it takes.

I know that the psp batteries do the same, but they hold a charge for a longer period.
Longer then my vita at least.

Thanks for the replies.

Its probably just low quality batteries. Like you said, the PSP I have (albeit old) couldnt hold a charge to save tis life (heh battery life, punny). I guess just make sure its charged when you want to use it?

I was hoping for this thread do dissappear somewhere between the pages and be forgotten.
It seems i must have forgotten to acctually shut it off the last couple of times.
Almost a month later the battery is still full.

Charging batteries overnight is risky because overcharging them decreases the battery life.

well strange....mine doesn't do that....probably you used it too much and it's starting to "rot" it's normal i guess?i remember a ds lite that i bought years ago and that after a year-time was to dump away because it kept turning off on his own.luckily i succesfully sold it at gamestop....

Assuming it's a lithium chemistry battery, self discharge is an indication of a imminent failure either catastrophic like battery fire or the more mundane failure where it never charges or holds a charge. Lithium batteries aren't known for having a high self-discharge problem.

But it seems after a month you're battery still works, so perhaps you had unrelated problem.

As for risk of overcharging...don't worry about that. Mainstream consoles like the PSP/Vita and cellphones have overcharge protection in their charging circuits, so it's not really something you need to worry about. If the console has a charging indicator light and it goes off on it's own when done charging, then it's not charging anymore and it won't overcharge the battery no matter how long you leave the power cable connected. Only cheap knockoff electronics and older tech might have problems with that.

You can't overcharge a smart battery - the internal circuit shuts off the charging process the moment the battery reaches its full capacity and only re-enables it after a substantial drop.
