Another day, another Samsung Galaxy S21 leak. Hot on the heels of comprehensive leaked spec sheets, a confirmed January release date and even a trio of teaser videos, we can now expect a major increase in battery life in the S21 – that's if a new leak is to be believed, anyway. 

According to the tip-off via smartphone specialist site PhoneArena, the S21 will not sport the 1440p screen found on the standard Galaxy S20. Instead, Samsung has chosen a more "frugal" 1080p screen – a claim supported by previous leaks a few weeks back. So the important new information is that because both the S20 and S21 are reportedly sharing the same 4000mAh battery, the S21 will see a two-hour bump in stamina, based purely on the new screen – and that's before we even get to the chipset onboard the newer devices. 

The Galaxy S21 Plus, meanwhile, is supposedly getting an even larger 4,800 mAh battery (up from the 4,500 mAh power pack found in the Galaxy S20 Plus) and the S21 Ultra should include the same 5,000 mAh colossus as its Galaxy S20 Ultra sibling. 

The lower resolution on the S21 and S21 Plus would mean that the pixel density will be downgraded from that of the S20 and S20 Plus. Yes, a potential  disappointment for Galaxy device fans who demand only the newest and most cutting-edge of displays from each year's update, but the stamina gains here are substantial – if, of course, this all turns out to be true. 

With fresh leaks springing up every few days regarding the hotly-anticipated Samsung Galaxy S21 lineup, you can stay up to date on our dedicated S21: release date, leaks and all of the news page.
