I used to take photos with Sony P8 before my last trip to U.S. The battery of the camera was complete dead. That is the reason I bought another one T10 in Tokyo airport.
However, I just few that T10 is not as good as P8, although it is smaller, with a bigger screen, and resolution is much higher.
Finally, I found out the reason.
P8’s aperture range is F2.8 – F5.6 while T10 is only 3.5. That makes a big difference.
For example, when the object is not briget enough, T10 is more likely to blur than P8.
How to Cure the Battery
I got a trick from my father. It is not professional, but it works. I wrapped the battery with newspaper and a plastic bag, and then put it into my refregirator. After two days, get it out and put it in the room for two days.
Now the battery is back! So far so good, and the charging capacity is almost like the new one.
Hm…. I know it is maybe dangerous, but at least it prove that it IS the battery problem.
I am happy that I can use my bigger Sony P8 again.
