Also, approximate number of 50 000 Galaxy S8 units were put on test, which is not a small number. The company have also decreased the battery capacity in the Galaxy S8 and S8 Plus, and made some improvements on the battery itself. It is now expected that the Galaxy S8 and S8 Plus will have better battery than the Galaxy S7 Edge. The lower battery capacity is making the device more durable, and it is also associated with a longer battery life. They surely don’t want to disappoint their users this time, and also offer them a longer-lasting device.
According to the R&D department of Samsung, the S8 should be able to keep 95 percent of its original battery capacity. That, compared to the 80 percent from what they’ve had on their batteries till now, is surely a great improvement. When it comes to the tests that Samsung have been doing, they’ve doing everything from checking the durability of the battery, to putting each battery on an X-Ray test to double check for any abnormal traits. Also, the batteries are tested for leakage, which took them about 5 days to complete.
As a conclusion, we can say that Samsung are serious about their new batteries, and wants to make sure that their devices will be safe for their users and not cause them any trouble.
