Solved Need explanation regarding Android charging

Specs: Windows 10, 8GB
I've got several Android smartphones. Recently, I bought a charging cable online for my Lollipop device. I faced a bit different issue. I'd be grateful if someone could explain this situation.

When I charge my device using the newly bought cable, it takes nearly 2 hours to charging cycle to be completed and I can use the device for about 2 days. But, the previous charging cable took 1.30 hour and battery power decreases within a day. Can a charging cable affect the battery like this?

Not an android user... but... I’ve seen more than a few reviews commenting about assorted charging cables (usb to Apple and/or other devices) having adverse effects when in use. Poor quality cables having very poor charging times.

Is this a cheap cable, and are there any user reviews for it around?

It seems to me very unlikely that the cable would make
any difference, but the charger certainly would. When you
say you bought a new charging cable, does that include a
new charger? It sounds like the new charger gives a more
complete charge.

✔ Best Answer
There are reviews on Amazon which report problems with some cheap cables. Most that I’ve come across were more iPhone related, but there are others too.

Most chargers (with usb output) are 1amp at least, whereas dedicated phone chargers (these days) are likely 2.2amp; and more recent usb chargers similar.

If a 1amp charger is not up to par and thus not delivering that 1 amp, then the device being charged will certainly take a longer time to charge up,

If a 2.2amp charger was below par it might still deliver at least 1amp.

Have you tried another charger? And any chance to try another cable. Test, try each item separately of course.

Since the new "cable" takes longer but gives a bigger charge, my
guess is that the electronics in the charger which determine when
charging is complete are what is different, not the current capacity.
If it was primarily the current capacity that was different, I'd expect
it to give a bigger charge, yes, but to do so faster as well.

Of course, it is all limited by what the battery can withstand. For
charging to take longer but result in a bigger charge suggests to me
that the new charger is probably safe for the battery, and may be
"smarter", with more advanced electronics.

I'm not an expert. Please correct me if I'm wrong!

No it's only the charging cable..But the cable is shorter (0.25m) than regular cable. To be honest, it's a cheap cable and I use various charger occasionally to charge the device including original charger.. Charging cable said to be 2A fast charging cable. BTW, I truly need to get know if a USB cable could affect the charging duration.As it seems cable cannot affect.Only charger can do.

Charging cables aren't just wires running from one end to the other. There are chips in there that perform several funtions such as sending signal to the charger as to what type of fast charge can be utilized, measuring current draw, etc. The cheap cables have crappy chips in them and can cause all sorts of issues such as what you are seeing.

It's really a bad idea to use cheap cables, not just because of wire guage but poorly programed chips.
