This morning my X5 it had the daylight notification box and a battery low notificationbox. I had fully charged my X5 the night before. I think the Daylight notification came on but the device did not turn it self of afterwards. Just curious if this happened to anyone else?

Hrmm I didnt get that... instead when I turned it on this morning it turned itself off. When I turned it back on it said something like daylight savings time set, please check if the time is correct type thing.

Yes, it messed mine up, had to do a reset and finally got it working

When I turned on my Axim X5 Yesterday (Upgraded to Pocket PC 2003), the low main battery warning came on. The battery was at about 6% and continued to fall. I was worried that some sort of software malfunction was causing it to drain, so I reset it.

I put it on the charger and backed it up to a CF card, just in case. I'm looking at it the next morning and it is still charged from yesterday.

Next time change, though, it's going to be plugged into the charger all night.

It ought to be there, anyway.

Any time you are not using your Axim and you are near an AC Charger or AC Connected Cradle........Your Axim should be charging. It's best to keep LiIon Batteries as fully charged as often as possible.

You Do NOT deep discharge LiIon Batteries before recharging, doing so will shorten the life of the battery.



Here's some LiIon Battery Information:

All Consumer LiIon batteries (other than coin-type) have circuitry in the battery itself, to prevent overcharging under any circumstances.

LiIon batteries are actually quite dangerous commodities and the only way they were allowed into the Consumer market was to include this circuitry.

Quote:

From First Link: The charge cannot be terminated on a voltage (Which is what the Axim's green light is indicating). The capacity reached at 4.2 Volts per cell is only 40 to 70% of full capacity. For this reason you need to continue to charge until the current drops, and to terminate on the low current. (Which is what the Battery's Sensing Circuitry is sensing, and then doing). It is important to note that trickle charging is not acceptable for lithium batteries. The Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous.

I leave it in the cradle most of the day at work, but on the weekends I keep it in my pocket and only charge it if it gets low. Normally, it will be above 80% all weekend. This was an exception due to the Daylight Saving Time issue that other users have been noting.

Before yesterday, I had never seen the battery ever go below 20% charge. I appreciate the information about the Li-ion batteries. My Workpad z50 battery died of disuse and had to be replaced.
