Pixel 5 rumors have started to gain some momentum and why wouldn’t they? Google is expected to unveil both the Pixel 4a 5G and the Pixel 5 later this year, but despite an earlier rumor talking about the flagship’s massive 6.67-inch display, it might fetch a rather disappointing battery capacity, according to a tipster.

More Pixel 5 specifications have been shared with @ImjustSayingJC, with new info claiming that the device may have a 3080mAh battery. To put this into perspective, the now-discontinued Pixel 4 XL has a smaller display but touts a much bigger 3700mAh cell. Apparently, the tipster believes that Google is testing out the same battery optimization techniques that Apple employs for its iPhone lineup, leading to improved battery endurance even though the actual capacity size is small.
