Solved: S22 Exynos Battery Drain on WiFi - Page 6

Members_eT66blW · ‎14-03-2022

Hi, I'm experiencing an issue with WiFi on S22 . When the phone is idle and connected to WiFi it can't switch to "deep sleep" mode and battery drains much faster then when on 4G.

Is this a known bug ? Does Samsung is working on a fix ? I need to keep the WiFi turned off currently to reduce the idle battery drain, which is pretty annoying. According to multiple threads on Reddit and other sources online I'm not the only one with this issue

S901EXXU1AVC9 is for snapdragons

Hi yes you are correct, and sorry I was confident to say that I had exynos because Singapore always gets exynos.. Apparently this time around this country got a snapdragon..didn't mean to mislead.

No change, it doesn't enter deep sleep on WiFi

Disruptor · ‎31-03-2022

Confirmed. Useless update for this. 😞 I didn't want to hate Samsung, they made me.
