The Google Pixel 8a is set to be supported by Google for at least seven years, with replacement parts available until the early 2030s. But how easy is it to repair the device yourself? A recent disassembly video found that while the back cover comes off easily and the protective glass over the cameras can be replaced without removing it, the battery is firmly stuck to the frame, making removal difficult even with isopropyl alcohol.
The Pixel 8a does not have vapor chambers like some other phones, relying instead on graphite and copper film, thermal pads, and a basic cooling solution for the Tensor G3 chipset. This has led to concerns about overheating during use. The device received a low repairability score due to the challenging battery removal process, although replacing the screen is relatively straightforward.
Overall, the Pixel 8a may be a durable device with long-term software support from Google, but DIY repair may prove tricky due to the battery design.
