Laser autofocus is used in favor of the S20 Ultra's time-of-flight camera. [23] The Note 20's telephoto sensor and the Note 20 Ultra's wide sensor use pixel binning to output higher quality images at a standard resolution, with the wide-angle sensor using Nonacell technology which groups 3x3 pixels to capture more light.

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
The lineup of the first three devices was unveiled at Samsung's Galaxy Unpacked event on 14 January 2021. The three devices served as the successors of the 2020 models. All devices' design scheme has changed drastically, redesigning the massive rear-camera module for a slimmer camera module incorporated with the buttons and a uniform appearance for the S21, S21+, and S21 Ultra.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Where is the gas constant, is temperature, ˙ is the uniaxial strain rate, is the creep stress, and for lithium metal =, =, / =. [ 108 ] For lithium metal to be used as an anode, great care must be taken to minimize the cell pressure to relatively low values on the order of its yield stress of 0.8 MPa. [ 110 ]
