Google’s Pixel phones have grown from a curiosity to become some of the best smartphones you can buy, featuring excellent cameras and lengthy support. Unfortunately, they are also gaining a reputation for battery defects. For the second time in a year, Google has announced that it will render some of its past phones almost unusable with a software update, and users don’t have any choice in the matter.
After nerfing the Pixel 4a’s battery capacity earlier this year, Google has now confirmed a similar update is rolling out to the Pixel 6a. The new July Android update adds “battery management features” that will make the phone unusable. Given the risks involved, Google had no choice but to act, but it could choose to take better care of its customers and use better components in the first place. Unfortunately, a lot more phones are about to end up in the trash.
Bad batteries
Lithium-ion has become the technology of choice for rechargeable batteries due to its high energy density and reliability compared to other options. However, storing and releasing energy day after day causes inevitable wear and tear. Electrolytes that transport electrons can decompose into flammable gases and puff up your battery into a spicy little pillow, for example. Batteries also form clumps of lithium ions called dendrites, which grow and can cause internal shorts. This damage is accelerated by heat, and batteries get warmer the faster and longer they charge.
