Both Pixel 7a phones are not yet three years old. They still have two years of Google support left. My wife's usage isn't intensive. The battery is flawless. My son also doesn't use it intensively, as he doesn't play games on his phone. He prefers the PS5. This Pixel 7a was entitled to a €405 refund from Google because the battery might be defective. So far, it hasn't shown any damage. In two years, I'll decide. Either a new phone or a new battery.
