While it is true that lithium ion batteries do not need frequent deep discharges and that doing so can actually reduce the life of the battery, the electronics in the battery do need occassional deep discharges to reset their fixes on "what is empty" and "what is full". The Battery University article linked from an earlier post says this if you read through the text. The recommendation is once every approximately 30 cycles.

The original post is still worded as if to tell people to never worry about any deep discharges ever again after the initial calibration, but that isn't really accurate.

I would consider editing the original post to recommend an occasional deep discharge about once a month and topping it off every night between those.

Mark

I received a CS1 battery with my 8700 but had a CS2 from a previous model. I used the CS1 battery for 2 recharges but swapped to the CS2 as it seemed to hold more charge. Now when I insert the CS1 battery the device powers up with a dim screen showing a large battery icon in the centre with a red slash through it. Even if I charge the battery for hours it still doesn't disappear nor will the device power up. If I put the CS2 battery in, it powers up as normal.

Any ideas what this icon may represent and why it won't power up??

Default ebay charger

I bought a charger for a spare on e-bay. Plug it in to the BB and there is no indication it is charging.

Any ideas why it wouldn't work?

Bump - anybody? Will the battery charge even if the BB is 'off'?

Default Battery life for Perl seems pretty poor

I had a 7230 made several 3-5 minute and at leat one 10- 15 minute phone calls a day, Lotus notes email wireless reconcile, had BBtoday and Berry 411 running. I was charging the 7230 every other day.

Now using a 8100... trying to do the same but with out the BBtoday installed.
finding the battery is at 50% by noon, I am really worried that the battery will not last the day, so I am "topping it off" by connecting it to usb/vehicle/wall charger when ever I can.

Any one else seeing similar battery issues with the 8100?

Have you tried at least one deep discharge to calibrate the battery? Lithium batteries need an initial (and occasional maybe once a month) full discharge cycle to find the limits of their charge so they can give accurate readings.

I found that the BB chat application was in use that might have had something to do with it... I removed that application, since I use sametime connect for IM and the battery now seams to be lasting longer...

I will try a deep discharge and see what happens...

Thanks for the tip.

What is considered a full discharge? When the low-battery indicator is on? I charge my 8100c every two days in the mornings. The battery is usually at 20-25% when I charge it.

Full discharge I would assume would be to keep the phone was kept on until it shuts itself off from lack of power. I usually just have the phone down to less than 10%. By then I believe it is almost ready to shut off the wireless radio.

Until the phone shuts itself off. Then charge it back up until it says "Charged" (and it couldn't hurt to leave it on charger for an hour or two past that, but probably unnecessary). I don't have my manual handy, but this may be covered in the manual under the "first time use" section.

I would spring for an extended battery, do the deep recharges, and you should notice execllent battery life, as long as you charge at least every 3 to 5 days, my two cents. I love my 8700, but miss my 7290, what great battery life!
