Google Pixel 4a Update Halves Battery Life for Some Users

A recent Google software update for the Pixel 4a, intended to improve battery stability, has unexpectedly halved battery life for some users. Investigations revealed that the Pixel 4a uses two different battery types. The Lishen battery, after the update, experiences a reduced maximum charge voltage and a 50% capacity decrease. Google offers free battery replacements, $100 Google Store credit, or $50 cash compensation, but a rollback isn't possible. This highlights the potential unforeseen consequences of software updates and the importance of manufacturer response.
