Default So, no access to battery compartment whatsoever ?

Ive noticed that just after a couple of months i have lost about 10-15% capacity (In hours) for the battery.

I was thinking that i might have to change it within 18 month or so, because i dont like the thought of not be able to watch a full movie before the juice is giving up.

Any opinions of hardcore-users out there? Will the battery keep up to intensive use over time. Would be interesting to hear about reports from longtime users batterywise.

And , is there a way of opening the case and change an old battery ?

Make sure you aren't running the battery all the way down all the time. Try to keep the batteries topped up. I charge mine when it gets down to 2 bars.

The P2 came out in Q4 2007, so there is absolutely no-one in this forum who's P2 will be 18 months old unless its a prototype

I think any battery with a correct output voltage (3.7 volts) and correct maximum size will do the trick.

The samsung stockbattery gives 830 mAH capacity , wich is very good. Imagine batterys at the same size with a 1000+ mAH,

That would be reaaaaally nice .

bobbismal : I have not found it out as yet. I Imagine that there are plenty of sources.

For a nice little "tutorial" on how to treat your LiIon battery, read this page. Know this page. Live this page.

The geek inside of you will be satisfied.

Questions : Could also overcharging the Li-ion-polymer sort of battery be the cause of diminishing capacity over time ? Ive read the "big" manual (100+ pages) at samsungs, and it is stated that charging the p2 has a timelimit of 10-12 hours, because it could damage the battery otherwise with overcharging ( The Li-ion-polymer is a slightly different sort from the Li-ion. And is a tad more choosy when charging)

And : I always thought that the P2 monitors its own battery, and closes the unit when the voltage drops at a specific number, to protect the battery, typically at 30-40% percent juice left, as in the case with laptops and phones.

Im confused.

Maybe i should be careful of not letting the p2 charge overnight, as im used to. Overnight means from early afternoon to morning = About 15 hours.

BTW : The tutorial was one of the best ive read in regards to batterys

First of all, charging overnight wont harm the device, it has a protection circuit to cut power when the battery is full. The battery runs at optimum somewhere below full charge, but you can't overcharge it. It just won't hurt it to charge it less than full every time.

Also, the device will shut down when the voltage from the battery drops below about 3.5 volts, but that isn't 30-40% charge left, that's when the battery is barely able to power the device. I'd say you'd be safe to just charge it every day if possible, and avoid running it to where it cuts off power.

My optimum charging schedule is pretty much this:

If it's used frequently, charge it every day for about an hour. More if you use it for video (maybe 2 hours a day then). Your battery will outlast your desire to keep the device.

I can't see that you're watching more than 5 hours of movie in a day, I mean, come on
