Default Charging the battery

Is it better to charge the my BB when I turn off the device? If I charge the BB device without totally turn off, is there any harm to the device?

The only time I have ever shut mine down is when I had to pull the battery for a reset. To be honest, I have never shut down any phone ever to let it charge.

My 8700g ran all day all night for almost a year! No problems at all!

I have the BB Pearl. So there is no need to totally shutdown the device to fully charge, correct? I want to make sure I am doing this right so I don't ruin the battery or the BB device.

Thanks for the response.

I leave mine on all the time. I have heard that you may need to turn it off and back on once in a while because there is some issue with the internal memory if I am correct. As far as charging I would think you could just leave it on all the time. That's how I have done it with all of my other phones too.

Thanks for sharing your experience. It makes me feel much better now because ultimately I want to leave it on while charging...but just afraid it might ruine something.

If you go to the FAQ. You'll notice a spot on how to get the best battery life of your phone. I know that not many people do the discharging thing but it says to keep the battery topped off when you can indicating that you can leave it on just fine. Whether your in the car or at work so the way I look at it leaving it on should be just fine. I have also done this with all of my other phones only turning them off to do a hard reset or to clear the memory.

Do a search under "lithium" and you should be able to find my threads and posts discussing battery charging.

NEVER do a complete discharge of a lithium battery, so to "refresh" it or whatever. That was a procedure for old nicad and hydride batteries to get rid of or prevent the memory effect.

NEVER let your battery discharge down to zero. That may ruin a lithium battery.

Your Pearl battery is good for about 500 to 700 full charge/discharge cycles. This does NOT mean how many times you charge the phone, it means how often the "cells" are fully charged and discharged. Your battery cells "keep track," so to speak, of how many times they are fully charged and discharged.

Generally, a lithium battery will last about three to five years before the cells die, at which time the battery will hold less of a charge or simply die completely. This gradual decline of lithium batteries takes place regardless of whether you use the battery or not. If it sits unused on a shelf for five years, it will NOT last five years from that point. Odds are it will not charge up because five years have come and gone.

Contrary to myth, it is better to charge a lithium battery from time to time. Not charging a lithium battery actually damages it, especially if you let it discharge completely.

It does not matter if a device is on or off when charging. Charge rate may be affected, but the battery itself won't care.

Lastly, and this is extremely general, a lithium battery sitting unused on a shelf or in a drawer discharges at a rate of about 10% a week.

All of the above applies to any lithium battery, not just the Pearl's.

Wow! Very good information. I learned a lot about litium batteries now. I will not buy a second battery just for backup.

Thanks so much for the info.
