Last year, Samsung unveiled a brand new design language with the Galaxy S6, and then a dual-curved display with the Galaxy S6 Edge. Many were in love with the design of the new Samsung devices, and loved the specs that came along with them. Even without the microSD card slot and removable battery. However, the big issue with the Galaxy S6 and Galaxy S6 Edge was the battery life. Sporting 2550mAh and 2600mAh batteries, respectively, they just didn't last long enough. Many were needing to charge their smartphone throughout the day, which isn't a fun thing. Now, it's looking like Samsung has listened and is adding a pretty massive battery to the Galaxy S7 Edge.
Reports point at the Galaxy S7 getting a massive 3,000mAh battery as well, a big upgrade over the 2550mAh in the Galaxy S6. Now FCC documents are pointing to the Galaxy S7 Edge getting a 3600mAh battery. It's understandable for the Galaxy S7 Edge to get a bigger battery, seeing as it is supposedly going to feature a larger screen, when compared to the Galaxy S7. Rumors that we've seen already point at Samsung doing quite a bit to improve battery life, and we're looking at two day battery life from these two smartphones. Although that is subject to how you use the phone, as always.
With their Galaxy A series, Samsung threw a huge 4,000mAh battery into the Galaxy A9 (2016), and many reports from those that have used the Galaxy A9 (2016) have stated that battery life is superb on that device. With a 6-inch display, a 4000mAh battery should do fairly well. What will be interesting with the Galaxy S7 and Galaxy S7 Edge is if Samsung has indeed just added a larger battery or if they have also improved the software that runs on both devices. Which is also important. Optimized software can make a huge difference in battery life on any device. Just look at the Nexus 5 and Nexus 6 after getting Marshmallow with Doze enabled. A huge difference in terms of battery life.
Samsung is slated to announce the Galaxy S7 and Galaxy S7 Edge at Unpacked on February 21st. Which is the day before Mobile World Congress kicks off. We're less than two weeks away from that day, and things are definitely getting interesting.
