Weakness but apparently the weak point of all smartphones. Autonomy! 1 day to 1 day 1/2. I was not used to that. Previously it was of the order of 5 to 7 days. However a smartphone, it is used much more. It quickly becomes adict ... nothing to do with concrete. To increase battery life, qqs small adjustments allow substanciels gains but do not double (unless you log out of the GSM network and wifi. What about the interest in this case?)
Very good product well manufacturer. Handle cover with care. However I can only recommend comprehensive protection enveloping the device.
