You plug your Nothing Phone (2) into the wall expecting it to race from low battery to full in under an hour, and instead the percentage barely crawls upward. A phone that should reach a full charge in about 55 minutes can suddenly feel like it is sipping power for hours, especially if you grabbed whatever cable and brick were closest. The good news is that on this model, slow charging is usually a setup, environment, or software issue rather than a dead battery, and most of the fixes below take seconds.
Work through them in order. The early steps are the safest and most likely to restore full speed, and the final two (a factory reset and contacting support) are reserved for when nothing else helps.
What Fast Charging Should Look Like on Phone (2)
Phone (2) genuinely supports fast charging, and it leans on the PPS protocol to do it. It carries a 4700 mAh battery and, with a compatible adapter, charges fully in roughly 55 minutes over the wire. Nothing's matching wired charger is its 45W PPS adapter.
This same model also supports 15W Qi wireless charging and works as a 5W reverse wireless charger, so you can top up earbuds such as the Ear set by resting them on the back. If your wired charging is dragging, the steps below are aimed squarely at getting the cabled speed back to where it should be.
Start With Nothing's PPS Charger and Cable
Fast charging on Phone (2) depends on the PPS protocol, and the phone is selective about what it accepts. If you plug in a charger that is not a Nothing PPS charger, the phone may not negotiate fast charging and will top up at a reduced speed instead.
For full-speed charging, switch to a Nothing official PPS-protocol charger paired with a Nothing data cable. Nothing's own optimum-charging recommendation sums it up, which is to use a Nothing PPS protocol charger, turn off the screen, and charge at room temperature (25C plus/minus 3C). If you have only ever used a hand-me-down brick, this single change often solves the whole problem.
Turn the Screen Off So It Can Pull Full Power
Even with the right charger, a bright, active display competes with the battery for power. Nothing's official optimum-charging guidance for Phone (2) is to use a PPS charger, turn off the screen, and charge at room temperature.
Leaving the display on, and especially leaving apps running, draws power and reduces the charging rate. Lock the screen once you plug in and you give the phone room to hit its fastest speed.
Keep Games, Video, and the Camera Off the Charger
Heavy apps are the enemy of a quick top-up. Avoid power-hungry applications, especially games, video, and the camera, while the phone is charging.
Running these while plugged in slows charging and heats the phone, which throttles the charge rate even further. If you need to use it, stick to light tasks and let the demanding stuff wait until the battery is full.
Charge Inside the 15C to 35C Sweet Spot
Charging speed on Phone (2) is sensitive to temperature, and both hot and cold environments slow it down. Nothing recommends charging in a 15C to 35C environment for normal speed.
If the phone has already heated up, restart it and let it cool before you try again. As a built-in safeguard, charging stops entirely when the device exceeds 47C, a high-temperature protection feature, so a warm phone left in the sun or under a pillow can refuse to charge at all until it cools.
Clear Lint and Debris From the USB-C Port
Pocket lint packed into the Type-C port is a surprisingly common cause of slow or stalled charging, because it stops the connector from seating fully. Check whether there is any foreign matter lodged in the charging port.
If you find any, clean it out with a dry brush or another small tool, then try charging again. Keep it gentle and dry; the goal is simply to clear the obstruction so the cable can make solid contact.
Swap the Cable and Adapter to Find the Weak Link
A frayed cable or a tired adapter can quietly cap your charging speed. Swap in a different cable and adapter to see whether one of them is at fault, and reseat the Type-C connector while you are at it.
It also helps to connect your charger to another device to confirm the charger itself works. If it will not charge that device either, the charger is defective and needs replacing. Where possible, test with a genuine Nothing PPS charger and cable to rule out a compatibility issue at the same time.
Restart the Phone and Re-Plug the Cable
A quick restart clears temporary glitches that can interfere with charging. If the phone is unresponsive while charging, disconnect the adapter and cable, restart the phone, then plug it back in and charge again.
If the screen is frozen and will not respond, you can force restart Phone (2) with the official sequence below.
- 1.Hold the Power and Volume up buttons simultaneously until the Nothing logo appears on the display.
- 2.Let the phone boot fully, then reconnect the adapter and cable.
- 3.Confirm the charging indicator shows the phone is taking a charge.
Update Nothing OS to Squash Charging Bugs
Software bugs can hold back charging, and keeping Nothing OS current is an easy fix. Phone (2) shipped on Nothing OS 2.0 (based on Android 13) and is officially updatable to Nothing OS 3.0 (based on Android 15), which Nothing confirms is available for this model.
To install the latest version, follow these steps.
- 1.Open Settings > System > System update (or System updates).
- 2.Download and install any available Nothing OS version, preferably over Wi-Fi.
- 3.Make sure the battery is at 40% or higher first, because the OTA upgrade is blocked below that level.
- 4.Avoid interrupting the phone while it upgrades.
You can also confirm an update is waiting by going to Settings > About phone > Software info; a red icon appears next to the Nothing OS label when a new update is available.
Back Up and Erase All Data as a Final Software Step
If charging still misbehaves after everything above, a factory reset is the last software measure before you treat it as a hardware fault. This is destructive, so read the warning carefully. Erasing wipes all apps, contacts, text messages, and other data, and that data cannot be restored.
Back up everything first, including third-party chat records such as WhatsApp. You will also need to verify your screen-lock password or Google account if one is set. When you are ready, follow these steps.
- 1.Go to Settings > System > Reset options > Erase all Data.
- 2.Confirm your screen-lock password or Google account if prompted.
- 3.Let the phone wipe and reboot, then set it up and test charging again.
When to Hand It to Nothing Customer Support
If none of the above restores fast charging, the cause may be hardware, such as the battery, the charging port, or the charger itself. At that point the right move is to stop experimenting and get it looked at.
Contact Nothing Customer Support through the official Nothing support channels for further assistance, including a possible repair. Have your model and a description of what you have already tried ready so the team can move straight to a solution.
Frequently Asked Questions
Why does my Phone (2) charge slowly with a charger that worked on another phone?
Phone (2) relies on the PPS protocol for fast charging. A brick from another phone may not support PPS, so the phone tops up at a reduced speed. Switching to a Nothing official PPS charger and Nothing data cable usually restores full speed.
How long should a full charge take on Phone (2)?
With a compatible adapter, Phone (2) charges fully in about 55 minutes over the wire, drawing on its 4700 mAh battery. If you are seeing far longer times, work through the charger, screen, temperature, and port steps above before assuming a hardware fault.
Does Phone (2) support wireless charging?
Yes. Phone (2) supports 15W Qi wireless charging and also works as a 5W reverse wireless charger, so it can top up accessories such as the Ear earbuds placed on its back.
Why does charging stop completely when my phone gets hot?
Phone (2) has high-temperature protection that stops charging when the device exceeds 47C. Charge in a 15C to 35C environment, keep heavy apps closed, and if the phone is already warm, restart it and let it cool before plugging back in.
Will a factory reset fix slow charging?
It can, if a software problem is the cause, which is why it sits near the end of the list. Because erasing all data cannot be undone, back up everything first, including third-party chat records, and verify your screen-lock password or Google account when prompted. If charging is still slow afterward, contact Nothing Customer Support.
