I ordered 3 microUSB cables over ebay. My phone was at about 50% battery and I wanted to use it as a hot spot for some browsing on my laptop, so I plugged it in, a charging icon appeared on the phone, my laptop showed it as a connected usb device and so I went about my business.
About 30 minutes later I checked the phone and to my dismay saw 45% battery. But ahh, I thought, I have been putting the poor little thing under too much pressure, acting as a WiFi hotspot must drain the battery quicker than it can charge via usb, perhaps even using my laptops usb port wouldn't output enough power. Unscathed I continued on and when I was going to bed I plugged the usb cable into a mains adapter and switched everything battery consuming off and content, went to sleep.
The next morning I was awoken by my phones alarm which got cut off unexpectedly. I attempted to unlock my phone which showed no more signs of life.
Why isn't my phone charging with these new USB cables?
For clarity:
- They transfer data with no problems
- The phone appears to be charging, showing all the signs and lights it normally would,
the cable that came with the phone works as you would expect, so its not a fault with the phone, - I think they slow the discharging of the phone, but I could be wrong.
Are these just bad quality cables? Is there a way to fix this issue?
4Do all cables in question have all connectors available? Look at the connectors - some cables only use two. Perhaps the phone is expecting one or the other. – Daniel Andersson – 2012-05-08T16:11:09.640
I have the same thing going on with my Nokia Lumia 800. If I use any other micro-USB cable than the one supplied it, it only charges with a tenth of the current. Anyway, this is off-topic for this site. – paradroid – 2012-05-08T16:11:54.313
@paradroid is it? sorry i only use stack overflow (as you can probably tell from my rep score) i thought this was the stack for this kind of question – Jacxel – 2012-05-08T16:13:42.423
WiFi hotspot like Netflix will drain the device battery faster the 500 ma usb port can charge it. This is very common, thats why you want a USB charger that can provide at lease 750 -1000ma of Current. – TheSavo – 2012-05-08T16:15:22.897
@DanielAndersson as far as my human eyes can tell the connectors are identical, i have no idea further than that. the cable that came with it is a lot thicker and has an angled head on one end, but those are the only differences i can see – Jacxel – 2012-05-08T16:16:28.427
@TheSavo perhaps you should read more of my question – Jacxel – 2012-05-08T16:17:46.333
@Breakthrough: I doubt it will. I have tried with various micro-USB cables along with different computers, wall chargers and car cigar-lighter port chargers. Any other cable than the supplied one charges at one tenth the current. Through testing I also discovered that car cigar-lighter ports work a lot faster than anything else (with the supplied cable). – paradroid – 2012-05-09T04:03:27.440
@paradroid alright, then the only way for the OP to determine the problem is to get a multimeter, and compare the cable's resistance (yes, each of the five conductors) to the stock one. If it's too high, then the problem is low-quality wires (i.e. poor conducting material, or lack of material to begin with). – Breakthrough – 2012-05-09T04:05:23.043
2@Breakthrough: But the same cable can still charge my brother's HTC phone fast. From what I can remember from a conversation with an electronics guy, it is the way the pins are connected as well as the phone's microcontroller which makes certain cables compatible, leading to an increased charge current. However, I cannot find the conversation in order to make an accurate answer. There are a lot of discussions on the web about this, for different makes of phone. It seems that the phone charger micro-USB 'standard', which Nokia was one of the main promoters, is not really a standard at all. – paradroid – 2012-05-09T04:25:43.000
Perhaps the difference is pin 4, ID. – fstx – 2012-05-09T07:00:23.577
So, if I turn the phone off and plug it in, it says its charging, but it still doesn't. infact it slowly looses charge – Jacxel – 2012-05-09T08:33:38.030
