GoKawiilPhone slowdowns after iOS and Android updates traced to background reindexing
After installing an iOS or Android update, phones run background processes such as Spotlight reindexing on iPhones, which can take hours or even days to complete. During this period, CPU and GPU usage spikes, leaving fewer resources for apps and animations, though performance typically returns to normal once indexing finishes.
GoKawiil's interpretation of the reporting above, not reported fact.
Older devices may struggle more with these temporary slowdowns since their chips are less powerful, and major software updates are generally designed around newer hardware, meaning aging phones may permanently run slower after certain updates. This suggests users with older phones should expect performance dips after big OS updates, with little they can do beyond waiting or upgrading hardware.
- Software updates trigger background reindexing that spikes CPU and GPU usage temporarily.
- Older phones with less powerful chips tend to be more noticeably affected by these slowdowns.
- Major updates are built for newer hardware, so some performance loss on old devices may be permanent.
