Recently, netizens have observed that the WeChat installation package for HarmonyOS 5 (428.9MB) surpasses the size of its Android counterpart (245MB), seemingly at odds with Huawei's claims of smaller software footprints and quicker performance. However, this discrepancy stems from fundamental differences in the underlying logic of the two operating systems. Android apps arrive as compressed packages that expand upon installation, whereas HarmonyOS and iOS apps do not require decompression, with the size listed in the app store reflecting their actual space usage. Android APK files, which rely on virtual machine decoding, tend to be larger. In contrast, HarmonyOS HAP files are compiled using the Ark Compiler, contributing to higher operational efficiency.
