that's true, i was surprised when i switched my phone because after 5years battery life was not so great anymore, my old phone without sim card and almost dead battery was able to wake me up 3 days later phone that couldn't last full day, lasted over 3 with about maybe 40% battery (idle and stationary but connected to wifi)
