Battery life on 800w

[Phone Insanity]

Cycling through the battery is a bunch of horse****. These batteries are rated for a
certain number of complete charges and discharges. Your hair needs conditioning more
than your battery does.

On a more positive note, my Treo 800w has push contacts/calendar, is checking 2 IMAP
boxes every 5 minutes. It's getting e-mails and I even use my phone to make calls or
perform other tasks. The battery lasts between 12 and 16 hours on a complete charge,
depending on how much talking takes place. If I didn't touch it, it would last even longer.

I am employing regular, sensible power-saving settings; I didn't download any special
programs, I am not running extra software and I am not worrying about bogus battery
techniques.

The 800w does have a battery problem: it's 12-16 hours instead of my desired 16-24
hours on a phone that powerful. That could only be accomplished with a larger battery.
The E90, which has a 1500 mAh battery easily lasts 2 days doing more. There is no
magic here.

Complete agreement here. I got my 800w a couple of weeks ago and checked a few 800w forums when I saw my battery was not holding up. People were saying it needed conditioning which is not true. If anything every single cycle lowers your battery capacity on this type of battery. It will never work better than the first full charge.

I have been tweaking every setting, turning off all the features, which is not exactly fun since I purchased the 800W for the features. Still the battery does not last a full business day.

People seem to think Palm was pursuing a thin form factor, maybe with an obsession over the iPhone, and this blinded them to designing the 800W for a proper battery for a WM6.1 with all these features. I agree.

An 1800 mAh battery would have had no effect on the footprint and add maybe 1 to 1.5 mm to the thickness, about 7 or 8 grams in weight, and about $2 to Palm's battery purchase cost. The 800W would then work as it should through a business day. It is after all sold as a business user handset.

Well gee... If cycling the battery doesn't help.. how come I'm actually a lot happier with the battery life then when I got the phone? If you look at the person who started the thread it was me and I'm actually not complaining about battery life anymore. I think cycling a battery is the same thing as breaking in a baseball glove or a cars engine when their brand new.

Because you are playing with all the functions less then your first few days and you may have turned some options off. There is no "conditioning" of this type battery.

"Lithium-ion is a low maintenance battery. No periodic discharge is needed and charging can be done at random. A random charge means that the battery does not need to be fully depleted before recharge. In fact, it is better to recharge before the battery gets too low. Full discharges put an unnecessary strain on the battery. A recharge on a partially charged battery does not cause memory because there is none.

. . . lithium-ion cannot absorb overcharge and no trickle charge is applied on full charge. This allows lithium-ion to be kept in the chargers until used. Some chargers apply a topping charge every week or so to replenish the capacity lost through self-discharge while the battery sits idle in the charger. Repeated insertion into the charger or cradle does not damage the battery though overcharge. If the battery is full, no charge is applied. The battery voltage determines the need to charge.

On the negative side, lithium ion gradually loses charge acceptance as part of aging, even if not used. lithium ion batteries should not be stored for long periods but be rotated like perishable food. The buyer should be aware of the manufacturing date when purchasing a replacement battery. Aging affects battery chemistries at different degrees.

Thanks. As you can see from batteryuniversity there isn't such a thing as conditioning this type of battery. It will never work better than the first few days and only gets worse over age and cycles.

I tend to believe my own experience as opposed to an article posted on the internet. Nightly charging has greatly improved my battery life after a few weeks and then it pretty much stablized. My Centro and 800w both showed this same behavior.
