Had massive issues with my 6s during the last weeks. Upgrading to 11.2 significantly improved the laggy behaviour issue. However the Geekbench 4 results are interesting. Benchmark numbers for my iPhone 6S: Compute: 5551 / Multi-Core: 1732 / Single Core: 1045 versus "normal" 6S Benchmark numbers (taken from the app): Compute 10143 / Multi-Core: 3994 / Single Core: 2376. In summary my iPhone 6s is SIGNIFICANTLY (~2x) underperforming in this benchmark to where a "normal" 6s should be. How trustworthy are the benchmark figures in the app? Any other ideas? For the time being this seems to justify the suspicions.
