Long battery backup is something that all classes of users appreciate on a smartphone. No matter how feature-loaded your phone is or how great its camera is, if it doesn’t have battery life to match, chances are that you will be unsatisfied and soon need to look for upgrades. This is why battery efficiency has been a key focus over the years, with advancements in smartphone chipsets, memory, and other essential components like displays and radio sub-systems. Modern chipsets have gradually shrunk their process nodes, enhancing power efficiency, while displays now support variable refresh rates to conserve battery life. Here we have compiled a list of some of the best phones that offer long battery life and a great overall experience.
