My Phone Won’t Turn On — Here’s What to Try First

4 min read By Ash · Clapham Junction

You press the power button and nothing happens. No screen, no vibration, no charging light — just silence. It’s one of the most alarming things a phone can do, but in most cases there’s a straightforward explanation. Work through these steps before assuming the worst.

Step 1: Charge It First

The most common reason a phone won’t turn on is simply that the battery is completely flat — so flat that the phone can’t show a low battery screen. Plug it into a charger (use a wall socket, not a laptop USB port, which delivers less power) and leave it for at least 15–20 minutes before trying the power button again. If the battery was truly depleted, you may see nothing for the first few minutes — that’s normal.

If there’s still nothing after 20 minutes, try a different cable and a different charger. A faulty cable is a surprisingly common culprit.

A completely flat battery can look identical to a dead phone. If the phone has been left uncharged for days or weeks, give it a solid 30 minutes on the charger before deciding something is wrong.

Step 2: Force Restart

Sometimes a phone freezes or crashes mid-boot and gets stuck in a state where it won’t respond to the power button at all. A force restart clears this without losing any data — it’s the equivalent of pulling the battery out.

iPhone 8 and later

Quickly press and release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.

Samsung / Android

Hold the Power button and Volume Down together for 10–15 seconds until the screen flashes or the manufacturer logo appears.

If the phone responds to a force restart, the hardware is fine — it was a software crash. Let it boot normally and keep an eye on whether it happens again. Repeated crashes can point to a deeper software issue or a failing battery.

Step 3: Look for Any Signs of Life

With the phone plugged in, look carefully at the screen. Is there any faint glow, even if the image is very dim? Can you feel the phone vibrate when you plug in the charger? Can you hear any startup sounds? These subtle signs matter:

Has the Phone Been Dropped or Got Wet?

If the phone stopped working after a drop, it’s possible the impact has dislodged an internal connector or cracked a component that isn’t visible from the outside. A phone can look physically fine but have internal damage that stops it booting.

If it’s been in contact with water, do not try to charge it. Water and electricity don’t mix — charging a wet phone can cause short circuits that permanently damage the board. Leave it to dry in open air (not in rice — that doesn’t work), and bring it in as soon as possible. The sooner water damage is treated, the better the chances of recovery.

Don’t charge a wet phone. If water got in, leave it unplugged and bring it to us. Charging while wet is one of the most common causes of permanent water damage.

What If Nothing Works?

If the phone shows absolutely no response to charging, force restart, or different cables — and there’s no obvious drop or water damage — the most common causes are:

The Short Version

Charge it for 20 minutes, try a force restart, and check for any faint signs of life. Most of the time one of those three steps gets it going. If not — especially after a drop or water exposure — bring it in and we’ll diagnose it on the spot for free.
