Hello at all,
I am new to E-Reader and habe a Sony 505 for 7 Days now. At first everything seemed to be okey, but now the Baterie is realy awfull: Yesterday Mornig I started the day with e compleet full Batarie, I read abeout 50 Pages throughout the Day and at Dinnertime I had one bar of Bateriepower left.
The E-book I am reading has the ending .pdf and I read it in "large".
What I did to the divice is: I updated the german-firmware to the US-Version so I coud youse the Personiser-Sorftware that is talked abaout a lot in this forum. I did flash the software and I juse the Clock wich shows in the left botten corner.
I am not jusing the mp3-Player and when I put the device away for some Time (maybe two houers or so) I don`t shut it down not even standby. But still: About 50 Pages and just 24 hours of Baterie? For todays moning it was totaly emty. Is there anything that could explain this or is my reader defect?
Thanks for helbping, Ilkyway
