In use "classic" (some call a few minutes + internet via 3G or Wifi constantly but with standby) battery need a charge every two days.
Simple and user-friendly with Android (I used before an Xperia and operation is identical).
Good resolution of the screen. I think 5.3 "is a maximum for a phone and I have long hesitated between the Archos 50 and 53 for my needs but the screen is important.
For the negative points rather long camera and average quality despite the ads 8M pixels (after I imagine that photographers do not use the phones for exceptional photos) and the hull that leaves fingerprints (but again, I'm not fussy; o)
Some are fans of Apple products, I prefer Archos whose value for money seems more interesting and I work a French company (but the products are assembled in China as among competitors).
I recommend.
