Last year LG’s smartphone sales declined, even after releasing the highly acclaimed LG G4 with better specs and a better camera with better manual settings and still keeping the battery removable, which Samsung ditched in favor of more premium materials like metal and glass. This year, however, LG is going to seriously bump up it’s game with the LG G5 with an all-metal body and a battery that’s removable via a tray that pulls out from the bottom of the phone. On top of that there are features like dual cameras on the back (and possibly even the front also), a fingerprint sensor on the back, a second “ticker” display on the top of the screen to display notifications, and an “always on” display uses very low power to display the time and other info on the main screen.
As far as the battery, there is speculation as to whether LG will make it much larger than the 3000mAh battery that was on the G4 and its predecessor, the G3, or whether they will make it smaller. Some speculate it will be made smaller and since it's rumored that the G5 will have a slightly smaller 5.3” display and with better battery life management, it won't be a problem at all. Others speculate that the G5 may have a 4000mAh battery which is huge but would make the battery last much longer.
To sum all this up - with dual cameras, all-metal body, removable battery, fingerprint sensor and second ticker display, this is going to be the best smartphone LG has ever made and will very likely be the best smartphone of the year.
The LG G5 is officially set to be announced on February 21.
