Battery Problem!

[Mazboy]

I bought my TH55 over a week ago and went home to start charging it. Nearly 6 hours later the 'Power' light was still red but when i turned it on it show the battery icon as fully charged with the lightening icon on top of it so i unplugged it and began using it.

Now i've gone to charge it again and i'm getting the same thing, the red 'Power' light stays on. Is this normal because i've only used it lightly this week and it doesn't feel like the battery lasted anywhere near as long as other people here have said it does.

Do i have a defective model?

Leave it plugged in over night, that will top off the charge, the battery indicator can go above 100%, it just shows 100% for a longer time.
charging till the power led turns off has been recomended from the start with all LiIon batterys.

Do you think it will have affected its performance very much if i did not fully charge it the first time but only from the second time?

Do a battery test with BatteryTIME (search for a previous thread), and post your result! :)

My battery is fully charged and will drop to 66% in about 15 minutes of surfing on the WiFi. I wonder if the battery went bad? It used to work great for hours and hours now it's at minutes.

NOW WHAT!!! I can't send my unit off to Sony for research? I will not function as a human with out my TH55.
:mad:

The full battery icon with the lightning bolt on it does not mean the battery is full. It just means that the device is plugged into the charger.

No Kidding ??:confused:

Now it's charging up as I use it. It went from 85% (and I watched it a few minutes) up to 90% then 93% as I am Using IT???

This thing is possessed!:eek:

It's best that try not to use it when charging it. No battery will work well or last when you using it while it is charging.

okay... a word about charging any battery.... (I am not an expert here, so my appologies to all EE's listening)

First how you detect a battery discharge: you monitor the voltage levels, it starts off at x.y volts and drops to x.x volts you have used the system.... you cannot use amps as the object using the battery pulls the same amps constantly....

Now: how you charge a rechargeable battery: you give it more volts than it has and it will draw an amperage from the charging source when it needs to be charged. Once it is charged, its amp draw falls to 0, or near 0.

Therefore, if you charge a 3.5volt system with 4.5v charge, it will initially read 4.5 volts from the charge voltage and drop rapidly as it gets to its charge level. Therefore the battery is not fully charged. If you charge the battery with 4.5volts, but it stops drawing current (amps) due to fully charged, it will eventually burn out the battery since the battery cannot maintain the full charge voltage within the battery. Thus charging systems have designed themselves to turn themselves off when the amperage draw drops to the appropriate level. though I think the lithium ions will not burn up.

So... what you can conclude is that you cannot use a battery discharge level (based on voltage) to measure battery charging level (based on amps) and vice versa.

on the clie, and most other battery "chargers" all you have is a single light, charging/not charging. The power light being orange is the charge light on the clie. and the discharge light has a level indication (battery symbol) or graph if you use battery-graph.

so there it is... you have to wait until the charge is finished (red light goes off) or the unit is not fully charged. Now if the light never goes off, you have a problem.... however, you are supposed to charge it for 12 hours from a completely discharged state. so 6 hours on charge is not enough.
