I bought a charging cable for my phone and it is noticeably slower than other cables. Anybody know what could cause this, is length a factor? The new slow one is 9 feet and my others are in the 3 feet range.
Phone charging cable?

Length is probably not a factor. Is it a USB cord that plugs into a little wall wart or is it a wall wart and wire all in one?
It's probably just a low amperage charger. There's "standard" chargers which are usually around 1.1 amps and then there are "superchargers" (what they call it depends on the manufacturer) that are around twice that. The phone will usually tell you that it's plugged into a supercharger, though.

Length is a factor also cables are rated for different wattages as well. If you look at the USB C spec there are cable ratings of everything from 15W to 100W and even a future spec that can output 240W. The best way to tell is by the cable amp/voltage rating. take the Amps*Volts and you'll get watts. The bigger the number the more power it can supply. However, there are also other factors like length and what sort of fast charging tech your phone uses. Here is a quick video that explains that mess:

charging from 'what' ?
A plug in the wall charger/adapter or a PC ??
There is a HUGE difference.
If talking about a USB port on a PC, it can easily be that the USB port setup has changed and will NOT allow 'fast' charging ? if the cable is 'smart' , what is it set for ??
Then there's which USB ? USB1,1.1,2.0,3.2,4.1,???
Oh yeah..which phone and HOW is it setup to charge ? How many aps are installed and running ? ALL running aps consume power and will slow down the recharge rate/time.
Easily 101+ reasons for 'slower' recharge time...

Thanks for the replies. It is probably the USB or length because I used the same charger with all the cables. I got the 9 footer on sale so it very well could be an inferior older USB. I'll just keep it for emergencies, it does work just very very slow.
The charger is a wall plug unit and it works great with the other cables.

Cables do matter.
Some are not designed to carry power on BOTH sides of the USB plug that goes into the phone. Because of this, only 1/2 of the total amperage is conducted. Only cables made for 'fast charging' carry power on both sides. Be aware that they are for charging only and often do not work for data transport. Length rarely is the issue.

With cheap no-name cables (Amazon, I'm looking at YOU!), length is an issue. They use smaller conductors. Many are not compliant with the USB specification. (For a few years I did device testing for one of the Big 3 cellular carriers. This is my bread and butter. I still have about a gazillion wall warts around.)
