Samsung has made some huge improvements in battery efficiency for the Galaxy S8 and Galaxy S8+. After a year’s worth of charging and discharging, the Galaxy S8 and Galaxy S8+ are able to maintain 95% of their effective battery capacity.
In comparison, the Galaxy S7 and Galaxy S7 Edge were only able to maintain 80% of their battery capacity after a year’s worth of charging and discharging. Obviously Samsung isn’t sharing any trade secrets, but there’s some obvious improvements in battery technology to make this happen.
You have to understand, lithium-ion batteries degrade rather quickly, and as it degrades, it starts losing its battery capacity. So, while the lithium battery in the Galaxy S8 and Galaxy S8+ still degrades, it’s at a much slower rate. That said, you can expect to get a whole lot more out of it in the long run.
These battery advancements aren’t going to get you much more out of your day-to-day use. What this really is is more advancements when it comes to the degrading of the actual battery. So, when you charge and discharge it (e.g. put it on the wire and then use it all up), it’s going to basically have a whole lot less wear and tear.
