Android phone won't charge
The phone is not taking charge or showing a charging indication. Check the cable, adapter and connection before assuming battery failure.

There is no charging indicator
Rule out damage and check power first; then interpret the waiting period.
It charges very slowly or only while off
Compare usage, temperature and power source before blaming the battery.
It only charges with a particular cable or position
Substitutions separate accessories from a port needing inspection.
There is abnormal heat or moisture
Safety interrupts diagnosis: do not force another charging session.
Only wireless charging fails
Confirm support and alignment; compare cable without treating it as a workaround for a damaged phone.
Diagnostic signals
- ObservationIt rings while the screen is black
- The phone is on: follow the black-screen guide rather than continuing to charge to turn it on.
- ObservationAnother cable changes the result
- With the same outlet and adapter, the cable or its contact becomes more likely; it does not prove the whole battery is healthy.
Step-by-step solutions
Check whether continuing is safe
Stop for damage or abnormal heat; if safe, identify the failure type.
Before connecting, look for swelling, unusual smell, physical damage or excessive heat without pressing or opening the phone. With any of these signs, stop charging and do not try another charger: seek authorized inspection. If too hot, stop using it and disconnect power if safe.
If there are no danger signs, note whether it shows an indicator, a rising percentage, an accessory warning or a black screen. That observation chooses the next branch; there is no need to try everything.
Isolate outlet, cable and adapter
Use undamaged accessories compatible with the model. With the same cable and adapter, try another known safe outlet. If the result changes, investigate the previous outlet/power strip; do not dismantle it. Otherwise keep the good outlet for the following comparisons.
Try a known compatible cable with the same adapter. If it charges, the previous cable or its contact is suspect. If unchanged, keep that cable and try a known compatible adapter. If it now charges, investigate the previous adapter or compatibility. Changing both together cannot distinguish them.
Only if accessories are intact and compatible, try that set with another device. If it also fails, focus on power/accessories. If it works, this does not prove compatibility with your phone: check its requirements. If a verified compatible set produces no response, follow the state-based wait and then service rather than buying blindly.
Interpret the wait and the screen
With verified compatible power, observe after one minute. In Google’s Android guide, a battery icon means off and charging; on models with a red light, it can indicate deep discharge and at least 30 minutes is advised before trying to turn on. Not all have that light: follow your model’s manual for timing and power button rather than random button combinations.
If an indicator appears, complete that wait without constant power attempts. If it can receive a call but shows no image, follow the related black-screen guide. If unresponsive after the specified time and safe substitutions, give those results to the manufacturer; repeating hours or cycles adds no new comparison.
Compare idle charging and a suitable source
If the percentage rises slowly, stop games/camera/hotspot and leave the screen off for a brief comparison with the same charger. Record percentage and time. If it improves while idle or off, usage or temperature contributes; this does not prove an Android fault or justify resetting it.
Compare with a compatible wall adapter: a computer port can charge more slowly or stop supplying power while asleep. If wall power works but the computer does not, investigate port power before the battery. On Pixel, check the model’s official USB-C/PD compatibility; connector shape and advertised high wattage do not guarantee the expected speed.
If it shows charging paused, a charging limit or a temperature warning, read that state before changing accessories: a configured limit is not no charging. If it only charges while off even when cool with verified power, take the record to the manufacturer to check usage and hardware; do not force tests under load.
Interpret intermittent contact without forcing it
With power disconnected, inspect the port with a light without inserting objects. If a known cable fits and charges steadily but another does not, stop using the suspect cable. If several only charge when bent or pressed, stop: holding tension can worsen connector damage.
For stuck debris, moisture, corrosion or looseness, use only manufacturer-specified cleaning/service. Do not use needles, metal, scraping, liquids or hot air. Wireless charging does not make a wet or damaged phone safe.
Stop testing for heat or moisture
If an unplug warning appears or the device is too hot, stop using it and disconnect it if safe. Let it cool naturally in a ventilated place out of sunlight; do not use ice, a refrigerator or heat to dry it. With swelling, smell or damage, do not resume charging once cool: inspection is required.
If there was only thermal protection without damage, follow the model’s instructions before resuming. On Pixel heat can limit charging; if it recurs while idle with appropriate accessories, stop further comparisons and contact support. With moisture, do not connect until the manufacturer says it is safe.
Compare wireless charging only if supported
Confirm that the model and pad support compatible wireless charging; not all Android phones or Pixels support it. Align as the manual describes and remove only a potentially interfering case, without placing metal objects between pad and phone. Use the power supply required by the pad.
If cable charging works but the pad does not, check pad, alignment and compatibility. If the reverse happens, prioritize port/cable checks; it does not prove the port is broken. If both fail with verified accessories or abnormal heat appears, stop and seek inspection.
Still not working?
Provide the model, observed indicator, waiting time and working/failing cable/adapter/outlet combinations. Do not open the battery or buy parts just because there was no image. Stop when a comparison resolves the failure or continuing is unsafe.
