Google's Pixel phones are known for excellent cameras and extended support, but recent software updates have affected battery capacity, making some models nearly unusable. The Pixel 4a and Pixel 6a have both experienced these issues due to battery management updates. Lithium-ion batteries are prone to degradation over time, which can lead to dangerous conditions like thermal runaway. While lithium-ion technology is reliable, heat and wear can accelerate damage, resulting in safety risks and increased electronic waste as many phones may be discarded due to these battery issues.
Lithium-ion has become the technology of choice for rechargeable batteries due to its high energy density and reliability compared to other options.
Batteries also form clumps of lithium ions called dendrites, which grow and can cause internal shorts.
Eventually, this degradation can lead to internal temperatures so high that the lithium-ion cells reach a condition known as thermal runaway.
Google has now confirmed a similar update is rolling out to the Pixel 6a that will make the phone unusable.
