Pixel 3a vs Pixel 4a 5G

Swappasaurus says...

Upgrading from the Pixel 3a to the Pixel 4a 5G means a year-over-year upgrade. Typically, this would bring modest improvements, but in the case of the Pixel 4a 5G -- there are some decent benefits. For starters, the Pixel 4a 5G has support for 5G networks. You’ll also see a decent improvement in the specs. The Pixel 4a 5G specs include a Snapdragon 765G with Octa-Core processor with 6GB of RAM and 128GB of storage. In comparison, the Pixel 3a has a Snapdragon 670 with Octa-Core processor, 4GB of RAM, and 64GB of storage space. Both models support fast charging, however, the battery grows from 3,000 mAh on the Pixel 3a to 3,885 mAh on the Pixel 4a 5G. Both models have an 8MP (f/2.0) fixed focus camera on the front, and they each have a 12.2MP dual-pixel camera on the back. But the aperture on the rear-camera improves a bit on the Pixel 4a 5G, going from f/1.8 to f/1.7. Otherwise, you will also be getting a larger display that sits on a phone with slimmer bezels. The Pixel 4a 5G display is 6.2-inches with a resolution of 2340 x 1080, a Gorilla Glass 3 glass cover, HDR support, and a 100,000:1 contrast ratio.
