- A Reddit user claims they fitted a Pixel 5a battery into a Pixel 4a for 17% more battery life.
- The modified phone has a slight bulge at the back, which the Redditor says is unnoticeable.
What do you do when your phone’s battery starts showing its age? You definitely don’t replace it with a higher-capacity battery from that phone’s successor. At least not without a good amount of knowledge, testing, skill, and, shall we say, an appetite for some risk. Why are we talking about this? Because a Redditor claims they managed to replace their Pixel 4a‘s 3,885mAh battery with the Pixel 5a‘s 4,680mAh battery.
