Samsung will increase the battery capacity of the Galaxy S23 and S23+, according to rumors. The vanilla phone will go up to 3,900mAh, the plus model to 4,700mAh (+200mAh in both cases). Only the S23 Ultra will stick with the capacity of its predecessor, 5,000mAh. But Samsung has come up with another way to improve battery life – Light mode.
This mode was introduced for Samsung’s foldables earlier this year and serves as an alternative to Standard mode. It prioritizes battery life and running cool over absolute performance.
According to IceUniverse, the drop in performance will be moderate while the reduction of power usage will be significant. Note that this is separate from the usual Power saving mode.
Light mode will not affect performance in games as the performance profile for them will continue to be controlled from the separate Game Booster settings as it is right now.
The new Snapdragon 8 Gen 2 is showing promising results, so the performance uplift from the new chipset may balance out the slowdown caused by Light mode. That said, the 8 Gen 2 is promising to be more power efficient than the 8 Gen 1, so battery life should be better (even before accounting for the larger batteries on the Galaxy S23 and S23+).
PS. the screenshot clearly comes from a Galaxy Z Fold4, so we have no idea how Light mode will actually perform on a real S23.
