Slow Charging Speeds | Phone (3)

So, the spec sheet says 65W fast charging and supports PD3.0. But when plugged in to power bank with PD3.1 that supports a max output of 140W, the Phone 3 only pulls a max of 17W. Actually slower than the Samsung phone its replacing which pulls around 20W. Using the same cable (the one that came with the Phone), my Steam Deck can pull upwards of 45W. I'm actually a little disappointed as I was hoping for faster speeds.

No one has seen more than 30W sustained charging or anywhere close to 65W. I get a burst of 50W once and then it goes back down to 30W. There is an issue with the PPS-handshake and I expect it will go unresolved.

So I'm now up to trying my fourth charger with my NP3, a HP 65W tablet charger, QC3.0 compliant and with PPS; it topped out at 17W. The highest I achieved is with another 65W QC3.0 PPS USB C charger, which got to 36W. My wife's 120W Xiaomi charger achieved 17W too. I suspect the NP3 is not properly communicating the most appropriate voltage (i.e. 20V for 65W), and is preventing the charger from going above 15V.

Something fishy is going on. Based on my real world testing, my NP3 will not charge at the advertised 65W. The ticket I raised with customer support induced the standard recommendation of using a 'CMF charger', and 'ensure you are charging at an ambient temperature of 25°C'. Anyone in the UK will know that 25°C is far from ambient, even in the summer. Regardless, what was advertised is not what was delivered.

jacoballinson I still dont understand why you want 65W if it is full charged in 30 minutes with 35 W.

Do you think 65W would double the speed with a fullcharge in under 15 minutes?

Anonymous1004

jacoballinson Discharge it to 1% and then try. It should only be charging at max speed when it's at low battery

jacoballinson

Anonymous1004 tried that, but still only charges at 35W maximum.

I have a ticket open with the Nothing technical team. They asked me to do the following:

Before You Start

Find Your Device Type: Go to Settings > About Phone to check your device model. This tells you if it’s a Qualcomm device (like Nothing Phone 1) or an MTK device (like Phone 2a).

Watch the Video: If you’re unsure, check the video guide here: Watch here.

Steps:

Dial *#*#569#*#* and select Charging.

Enable Screenshot, Record Screen, and Bug Report.

Choose NOT REBOOT.

Reproduce the charging issue.

When it happens, press Volume Down + Power for a screenshot.

Dial *#*#569#*#* again or tap the notification.

Tap Stop Capture and wait for Log Saved.

Press OK.

In the Log Tool, tap the top-right corner, select Log List, long-press the log file, and choose Copy.

Open File Manager, go to Internal Storage > NtShareLog, upload to Google Drive, and share the link with support.

Log Files You’ll Get:

charging_log_Xxxx-XXX.ZIP (charging data)

bugreport2025-xxxx.ZIP (device overview)

Note: If the log doesn’t save, restart the Log Tool and try again.

Hi Community,

I am using the cmf 65W gan charger with my Np3. I just bought it today and only had a chance to charge the device from 50%-100% and I got a sustained 20W charge till it was about 80% and it kept on decreasing with time.

No one has had 65w charging you can search the whole of the internet, no one. I've got the CMF 100w Gan and it's never been over 35w. So if nothing are saying it's the charger it's not it's the PPS protocol. Just wish they would say it got a maxed out charge rate at 50w or so.

I have submitted a formal ‘enquiry’ (for want of a better term) to the Nothing customer service team. They asked me to submit some log files and screen shots to their technical team, who are reviewing the information. Initially the have suggested:

We understand your concerns regarding the charging speed of the Nothing Phone (3). Based on your report and the logs, it appears that your phone is currently charging at a maximum of 34-37W, which is below the the advertised 65W.

After reviewing internal testing and community reports, we would like to clarify the following:

Device-side charging negotiation: The Nothing Phone (3) adjusts charging voltage and current based on several factors including battery temperature, ambient conditions, and charger compatibility. This is designed to protect battery health and ensure long-term device reliability.

Charger compatibility: While your UGreen 65W GaN charger is QC3.0/PPS capable, some multi-port chargers may not fully negotiate the PPS voltage curve to reach the maximum 65W on Nothing Phone (3).

System firmware optimization: NOS 4.0 includes safety mechanisms that may limit charging speeds under real-world conditions. Future software updates may further optimize PPS negotiation and improve maximum achievable charging speeds with compatible chargers.

Temporary suggestions to try:

Use the original Nothing Phone (3) charger and cable rated for 65W PPS for testing, if available.

Ensure ambient temperature is within 20–30°C range; extreme cold or heat can throttle charging.

Test with a single-port PPS charger rather than a multi-port GaN hub.

We appreciate your patience while our engineering team continues to investigate this. The team is reviewing the PPS negotiation and charging algorithm to see if further improvements can be delivered via software updates.

This solution is absurd.

I am using the CMF charger 65W (Offical charger as per Nothing) with the cable that came in the box.

Currently it is Winters in India and the temp ranges from 10-18°C these days.

With these conditions, I am getting 21W as max wattage while charging while the same charger is charging other devices at around 60W.

Clearly a Nothing issue.

jacoballinson Use the original Nothing Phone (3) charger and cable rated for 65W PPS for testing, if available.

They don’t sell an official cable afaik?

Can someone with the original charger send results for Phone 3(a) here too. I don’t think it’s at max speed even though it is pretty fast

dreddit

Think this answer from nothing is pretty poor. And I really wonder why that sell chargers under CMF brand when none of the CMF phones charge near 65w, never mind 100w. Why not release a charger under the Nothing Brand. Then explain why the phone charges at 36w.

I have a 100W charger, the device has never charged over 35W. In the UK the temperature is rarely above 25 degrees Celsius throughout the year

jacoballinson

georgios1 based on what my AccuBattery app is telling me, my battery is rarely below 20°C, even when idling. The phone will sit generally at 3-5°C above ambient, so indoor ambient should be enough to keep the battery/phone within that magic “20 to 30°C” range.

geoxarg

One can only feel the burden of slower charging if they have ever owned a phone like OP13 that charges lighting fast compared to Nothing Phone 3. Hard to digest but it is ok

code913

geoxarg Friend at school once told me to put his oneplus phone on charge. 60% or so

He took it out few minutes later and it was 80
