charging your UX50 overnight?

[mtsingson]

just wondering, would it be advisable to charge the UX50 overnight? will this be bad for the clie's battery or performance? i once had a nokia 9210 and charging it over night wasnt advisable since it overheats the phone and ive read in the "9210" forums of people who experienced their phones getting destroyed because of this

would the UX50 suffer the same circumstance? how long do you charge your clies? and how long does it take to fully charge? mines been on the cradle for two hours already and the "charging" light is still on

Regardless of how much I've used it during the day I charge my UX, with the extended battery, every night overnight. I do however use it a LOT. It will not hurt it at all, when it is fully charged it simply shuts off. And usually it is recommended to charge as often as possible anyway. So just drop it in the cradle at night and it will be ready to go in the morning.

aaah the beauty of Li-ion.

Charge as you please and no battery memory problems!

With lithium and lithium-ion (what the UX50 uses) batteries, it seems that long charging (overnight or several days) does no harm, in and of itself. The same was prossibly true of the phone mentioned in the original post. The older nickle-cadnium batteries, excessive continious charging can hurt the battery if the charger isn't "smart" enough to drop back to a trickle charge when the battery reaches full charge.

Excessive heat, whether produced in the battery by excessive charging or radiated from the charging circuits, can damage a battery. The best test is to monitor the temperature of the unit while charging.

I regularily charge my UX50 overnight (~10-12 hrs.) and occasionally charge it over a complete weekend (Fri pm - Mon am). I have never noted any heating above skin temperature. I also charge my Motorola cell phone in the same manner and its battery life, after 2 years, seems to be at least 85-90% as good as when new. My older Clie T415 (lithium battery instead of lithium-ion, I believe) sits on the charger 80% of the time and still gives what seems to be 100% the battery performance that it did when new 1.5 years ago. All three devices have the AC-DC conversion "brick" (a major source of heat in some designs) well separated from the device being charged and neither heat while charging.

the battery can much more harm a deep discharge.
lion/lipol batteries have better life when charging very often (aven at 90% ) they have then more recharging cycles ..
