Google Pixel 4 vs Xiaomi 15
The Verdict
Xiaomi 15 decisively outperforms Pixel 4 across nearly every hardware metric despite costing $200 less. The Xiaomi features a substantially larger 6.36-inch LTPO AMOLED display with 3200 nits peak brightness and 1-120Hz refresh rate versus Pixel's 5.7-inch 90Hz panel at 600 nits. Processing power heavily favors Xiaomi: Snapdragon 8 Elite with dual 4.32 GHz cores demolishes Pixel's 855 chipset from 2019. Battery capacity nearly doubles at 5400 mAh with 90W charging compared to 2800 mAh and 18W wired. Camera systems both impress but differ in approach: Xiaomi offers quad cameras including 50 MP main with Light Fusion sensor and 8K video, while Pixel 4 excels at computational photography with its proven 12.2 MP system. Xiaomi includes 12 GB RAM and 5G connectivity; Pixel offers 6 GB without 5G. The only Pixel advantages are weight (162g vs 191g) and proven software optimization. Xiaomi 15 is the obvious choice for value-conscious buyers prioritizing specs, display quality, and modern connectivity. Pixel 4 only appeals to those prioritizing camera tuning legacy and lighter form factor despite severe hardware deficiencies.
