If new leaks are to be believed, the Samsung Galaxy S21 will have significantly longer battery life

According to a leak via PhoneArena, the S21 will not feature the 1440p screen found on the regular Galaxy S20 Instead, Samsung will opt for a more modest 1080p screen; since the S20 and S21 are said to share the same 4000mAh battery (model EB-BG980ABY), the S21 will get two hours of battery performance from the new screen alone

Meanwhile, the Galaxy S21 Plus is said to have an even larger 4,800mAh battery (up from 4,500mAh), and the S21 Ultra should have the same mammoth 5,000mAh battery There are other reasons for optimism

The lower resolution of the S21 and S21 Plus means that their pixel density will be lower than the S20 and S21 Plus This is unfortunate for Galaxy fans who demand the highest specs for each year's model, but the benefits are significant

According to comparative testing by Android Authority, full HD (FHD) screens offer an average of 24% better battery life when compared to quad HD (QHD) displays This translates to an extension of 176 minutes

Beyond the new lower-resolution screen comes an even more efficient chip: the S20 uses the Snapdragon 865 7nm processor; the S21 will feature the Snapdragon 888, which uses Samsung's new EUV process, down to 5nm This should reduce power consumption by 20% compared to the S20

The Snapdragon 888 will also feature an X60 5G modem on the die itself, helping to increase efficiency over the S20, which used a separate 5G chip
