In my S23 FE, when I turn on the hotspot tethering, the battery goes down like a bullet train. If I plug in the charger, even though it's showing super fast charging, in reality, it's charging like a tortoise. If I turn off the hotspot, then it charges fast. Also, network sharing is too slow, even though it's 5G.
Another pinpoint: if the battery goes down to 10%, within the next 3-5 minutes of normal usage (just the screen on), it goes to 0%. I mean, 10% is equal to 0% in usage.
