Copio y pego una review de alguien que compró la ONDA V811, en la web de la marca, atención a los comentarios sobre la batería:
The Onda V811 comes with Android 4.0.3 with Google Play Store installed. First the bad points: The built in camera is very very bad. You can’t use it at all. Why you built in this one with such a bad quality. It makes no sense. The battery is also very bad. If I use the Onda for internet -> after 2 hours the battery is empty. Even when I charge it and use the full brightness too see something, the battery power becomes less and less. I never had a device like this. The 32GB SDHC card doesn’t work. 16 GB works but not my 32 GB. Also the micro USB connector does seems to be so good. Now the good points. The price is really good. The screen is good even when it has only resolution of 976x768 . The cpu is fast enough the graphic is good. It is light and the 8” screen is perfect. 7” was to small and 10” too big for me so 8” is perfect. The touchscreen work fine and smoothly. The price is the best reason to buy it. (Posted on 9/28/12)
