OK, here is a small snippet of code as an example.
Source code
public PowerSaveSettings ReadPowerSaveSettings()
{
    if (this.powerSaveSettings == null)
    {
        ELMPowerSaveSettings elmSettings = null;
        STNPowerSaveSettings stnSettings = null;
        
        // Do something...
    }
    // Do Something
}
Decompiled code that was obfuscated
public PowerSaveSettings ReadPowerSaveSettings()
{
    if (this. == null)
    {
        ELMPowerSaveSettings elmSettings = null;
        STNPowerSaveSettings stnSettings = null;
        
        // Do something...
    }
    // Do Something
}
The elmSettings and stnSettings are local variables that are used in this method. I cannot show the implementation the rest of this method, but the idea is that the variable names are not obfuscated.
