Xiaomi launched the Redmi Note 9S as a rebranded Redmi Note 9 Pro Indian variant. It is one of the best budget smartphones in its price segment continuing the legacy of Redmi Note series. But lots of users are reporting a weird WiFi issue on this handset.
Multiple Redmi Note 9S users have shared a common WiFi bug on forums like Mi Community and XDA. According to them, the phone randomly disconnects from the internet on WiFi after 10-15 minutes from locking the screen.
Also, the data transmission won’t resume on WiFi even after unlocking the phone. The issue seems to be limited to the European variant of the handset as there are no reports from Indian users.
Some users claim the latest MIUI 220.127.116.11 Global Stable build partially fixes the bug as per Android Authority. The fix in question involves the phone logging out of the network every 10 minutes, followed by a login within a few seconds but this is not a perfect solution.
On a regular basis, all Android devices reconnect to a WiFi network every few hours to renew the IP address. But the Redmi Note 9S is doing the same procedure for every few minutes. This is absurd even when we think of it.
We hope Xiaomi fixes it properly via future OTA update as it seems like a software issue rather hardware as units running MIUI India build does not have the same problem.
