A room can have heavy curtains and still glow around the edges. Light may come from the hallway, a streetlamp beside the window or the charging indicator directly opposite the bed. Buying another layer of fabric will not solve all three problems.
Look around from pillow height after the room is set up for the night. You are checking the view you actually have, not how dark the bedroom looks from its doorway. Note the brightest patch, then deal with that one source first. This keeps a small adjustment from turning into an unnecessary curtain replacement.
Work around the window
If light slips down the sides, check whether the curtain rod extends far enough beyond the frame. A wider curtain may cover the gap better than a thicker one that ends in the same place. If light comes through the fabric itself, a compatible lining or a removable shade could be worth considering. Measure the window and the mounting space before ordering anything.
Renters can look for removable options, but read the mounting instructions and check the surface. An adhesive that works on smooth tile may fail on textured paint. Keep window coverings clear of heaters and avoid loose cords where children could reach them. Do not block an opening needed for emergency escape.
Keep a usable route
Total darkness is not more important than moving safely. A small, shielded light near the floor may make a bathroom trip easier without shining toward the bed. Try its position while you are awake. You should be able to identify furniture edges and the doorway without hunting for a switch.
For device lights, use the device's settings where available. Do not cover ventilation slots or safety indicators to hide a glow. Moving an unnecessary charger out of the room may be simpler than modifying it.
Finally, ask anyone who shares the bedroom what they need. A hall light might be helping someone find the bathroom or check on a child. Redirecting that light can be a better compromise than switching it off. Once the main bright patch is gone, live with the arrangement for a few nights before adding another product. A room that works comfortably is the goal; a perfectly black photograph is not.
