Reports had indicated that the Galaxy S8 and S8 Plus might have a bigger battery than the predecessors, but Samsung is playing it safe to avoid the disaster that the Note 7 brought their way. The Galaxy Note 7 featured a 3500 mAh battery, which was bigger than its predecessor, and may have been one of the reasons why the battery exploded. Samsung blamed the batteries inside the phablet for the explosions, but it also admitted its design and manufacturing requirements may have led to explosions.
The Investor says the Galaxy S8 and S8 Plus will have smaller batteries than initially expected. The Galaxy S8 will pack a 3,000 mAh battery, while the phablet version will have a 3,500 mAh battery — these are almost the same capacities used last year for the Galaxy S7 (3,000 mAh) and Galaxy S7 edge (3,600 mAh). Previous reports said the Galaxy S8 versions will have 3,250 and 3,750 mAh batteries.
Samsung has apparently started receiving smartphone components in large volumes, as it prepares for mass-producing the Galaxy S8.Reports say that Samsung made some changes to its battery supplies after the Galaxy Note 7 debacle, by adding Japanese company Murata to its supply line. However, Samsung SDI and ATL, the makers of Galaxy Note 7 batteries, should also provide batteries for the Galaxy S8 series.
