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.

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.

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

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

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.

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

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
