* Autonomy has approximately doubled, which is not luxury on the S3 G Lte (less than 5 ~ 6 hours in sustained stress): phone holds 1.5 to 2 days without problem (Wifi active, Datas, GPS ). In standby, I greatly exceeds 3 days.
* No problems at (cooldown or other): I'm looking, I can not find one!
This is what I wanted and what Samsung kit does perfectly well: we really wonder why this phone was not originally equipped with this battery ??? May be to sell S4?
