A Pixel 10 that will not charge is far more often a cable, adaptor or port fault than a dead phone. Work the chain in order — charger, cable, port, battery — because each check rules out the cheap failure before you pay for the expensive one. If the phone still shows nothing after 30 minutes on a charger you know works, stop guessing and bring it to our bench inside Piccadilly Circus Underground Station for a free diagnostic.
Start with the charger, not the phone
Test the power chain before you blame the handset. Google's own first step is to try charging another device with your power adaptor and cable, check that the cable is securely connected at both ends, and check that there is nothing in the port of your phone, like dust or lint [1].
Swap one thing at a time, or you will not know what fixed it:
- Put your adaptor and cable on another device. If that device charges, both are alive and the fault is in the phone.
- Keep the adaptor, change the cable. USB-C cables fail at the moulding where they bend, and a cable that still passes data can have a broken power conductor.
- Keep the cable, change the adaptor.
- Change the socket. A switched extension lead with a dead switch has cost more than one customer an afternoon.
If your Pixel throws a Check charging accessory notification, take it literally: that message means the cable or USB power adaptor may be damaged or not supported by the phone, and it can make the phone charge very slowly or not at all [1]. Replace the accessory before you book any repair.
Read the USB-C port before you read the phone
Pocket lint does not blow out of a USB-C port — it compacts into a felt pad at the bottom, and the plug then stops about a millimetre short of the contacts. The phone reports nothing because nothing is touching. Google lists a clear port as one of the first checks for exactly this reason [1].
Use these signs to tell a blocked port from a broken one:
- The plug does not click in fully, or sits proud of the frame. That is debris, not damage.
- It charges only at one angle, or when you press the cable down. That is mechanical — a worn connector or failed solder joints on the port, and it needs a port replacement rather than a battery.
- It charges wirelessly but never over the cable. The battery and charging circuit are working; the port or its data lines are not.
- The port looks dark, green or crusted. That is corrosion from liquid, and it wants a bench, not a cotton bud.
Do not dig it out with a paperclip or a pin. The contacts sit in a single row at the bottom of the connector, and bending one turns a clean into a port replacement. We inspect and clean ports under magnification as part of the free diagnostic, and we tell you which of the four cases above you are in before any work starts.
Separate a flat battery from a dead phone
A phone with nothing on the screen is not necessarily a phone with nothing wrong with the battery. Plug it into a cable, charger and socket you have proved work, wait a minute, then read what it gives you. A battery icon means the phone is powered off and charging. A steady red light means the battery is fully discharged. A flashing red light means there is not enough power to turn on, and the phone needs charging for at least 30 minutes before you try restarting it [1].
Hold the power button for five to seven seconds first, which restarts most phones [1]. If you get no icon and no light at all, the problem may be the screen rather than the charging circuit. Reboot by pressing and holding the power button for about 35 seconds, wait about two minutes, then make the phone ring from another phone or the Find Hub app — if it rings with a blank screen, the phone is alive and you need a screen replacement, not a charging repair [1].
When it really is the battery
Two patterns point at the cell rather than the port. The first: it charges, but the percentage climbs slowly and falls fast, and the phone shuts down while it still claims charge in hand. The second: it only charges when it is switched off, and drops as soon as it is woken. Both are a battery replacement, and both are same-day work in the shop.
One symptom overrides everything else. If the back glass or the display is lifting away from the frame, or the phone has developed a rock on a flat table, take it off charge and bring it in that day. We do not put a deformed cell back on a charger, and neither should you.
Heat and the wrong charger are what get most batteries to that point. Google is blunt about both: other power adaptors and chargers can charge slowly or not at all, and can also damage your phone or battery, and overheating drains the battery much faster and that drain can damage it [2]. A phone that charges on a car vent mount in summer traffic, in a case, is being cooked every commute. The same failure pattern shows up across brands — we walked through it for Apple hardware in our guide to an iPhone 15 battery draining fast.
Back up before you hand it over
If the phone still powers on, back it up before you set out. Content, data and settings go from the phone to your Google Account, and a Google One backup can take up to 24 hours to complete, so start it the night before rather than in the queue [3].
If it will not power on at all, do not write the data off. Bring it in as it is — a phone that cannot charge usually still has an intact storage chip, and data recovery is a separate job from getting it running again. Tell us at the counter that the data matters, because it changes the order we do things in.
Bring it to the bench
Bring the phone, the cable and the adaptor. Testing the whole chain takes minutes with the phone in front of us and is guesswork over the phone.
