Much has been said about the upcoming Galaxy S7 lineup, but as we get closer to the launch date, it seems like the information is a little more reliable. Samsung finally released a teaser video for their Unpacked event, which will take place on February 21st, and the company will surely announce a few devices including its new flagships. We finally could confirm the existence of the Galaxy S7 Edge, as its name was spotted in a developer's site created by Samsung, and that device is expected to be announced along the Galaxy S7 with a flat screen.
We've already seen some leaked images of both devices and they resemble the current flagships quite a lot, although the Galaxy S7 Edge is now larger. Samsung seems willing to correct some aspects that were criticized on the Galaxy S6 lineup, the new phones will apparently integrate a Micro SD card slot to expand the internal storage and the battery, even if it still won't be removable, it seems that it could last for quite a while. Eldar Murtazin from Russian site Mobile Review mentioned that the phone could last for up to 17 hours playing video and with the screen set at full brightness. Now, he shared a few screenshots, allegedly from the Galaxy S7 that show how the battery behaves. He claims that the new generation of Samsung smartphones lasted for two days on a single charge with brightness at 75%, LTE turned on all the time and two SIM cards running. This could be a significant improvement compared to the battery life of the Galaxy S6 lineup, which can barely last for a day
He doesn't specify which of the two phones these screenshots belong to, but the Galaxy S7 is said to include a 3,000 mAh battery and the Galaxy S7 Edge could integrate a 3,500 mAh battery to compensate for the larger screen, so both handsets could end up having a similar battery life. Let's also note that these handsets will probably launch running Android 6.0 out of the box, which has been optimized to manage the energy a little better. Still, we will have to wait until the official announcement to confirm all of this.
