Hey guys just got my ipv4s and noticed something weird and hopefully it's normal... If I press the up/down button the display will only stay on for like 5-10 seconds... But if I press the fire button it will stay on much longer maybe a minute least... So I've been taking a pull and then immediately pressing the wattage up for my display to turn off... Maybe this is causing some battery drain... So I was wondering if anyone had this issue or if it's normal.... Take a pull set down your mod and see how long it takes for display to turn off.... After the screen is off press up/ or down button and see that it only stays on for a few seconds... Very annoying to me... Let me know if it's just my device
