I bought a used Touch Lux 3 (it turned out to be the original, heavier version). The battery was completely dead when it arrived, so I figured that's probably why the seller got rid of it. I charged the battery, it seemed good, and I was using it without issue. Turned it off and when I turned it on again, it had dropped below 50%. Charged it again. Next morning it was completely dead.
So I bought and installed a new battery. It took a "good" charge. Seemed to hold it fine — until it didn't. Same behavior as the old battery.
I tried erasing the internal memory and doing a factory reset, taking it out of the cover (with magnet) and turning it completely off each (instead of putting it into Sleep mode) — nothing seems to help.
I've seen that this was an issue in the past on this model. Is it possible that the Touch Lux 3 needs to be somehow "calibrated" to the battery, or that it thinks the battery is charged when it really isn't? Seems to me it charges way too fast. I was never able to find if there was a fix for this in the past. It's possible that my replacement battery is defective, I suppose, but it still doesn't explain the sudden drops in charge, instead of a steady decline.
Sorry for rambling. Just looking to see if anyone has run into something like this and whether there was a fix. I'm also wondering if there could be a short somewhere, but (again) it seems like the issue would be more consistent if that was the case.
I have learned enough from the Touch Lux 3 to know that I want to upgrade to a new PocketBook. Not sure yet if I'll be cheap and get the Touch Lux 4 or go for the Touch HD3.
