Not Fast Charging

[tony.wheeler]

I find that my U11 is now frequently not fast-charging even when using the supplied charger. In some cases I found that pushing in the USB C connector (firmly) fixed the problem.

I'm using fast chargers and leads that worked fine with my HTC 10. Any ideas? Are others experiencing problems?

I hope I've not got a faulty device.

this is one thing I was afraid of, what to do when the USB port gets damaged

how to keep it charged.

if we had the option for wireless charging, then at least even if the USB is damaged, we can still wireless charge, but unfortunately this beautiful phone did not come with the wireless charge feature.

Have you checked the USB C port on your device for dust or something of that sort that could be preventing proper connection?

Are you using the OEM usb cable with it too? I only had problems with aftermarket cables on my U Ultra.

At work I have this pre-historic (10+yo at least) thin white generic mini USB cable with mini to micro and micro to C adapters, supplying power from Samsung fast charger (unofficial qc 2.0) and still "Quick Charger connected"

Will try if better cable charges faster though - with backlight all the way up and Pokemon go running (inside building, GPS roams a lot) it just keeps the charge level, with low backlight it charges.

Huge improvement over Xperia Z3+ (Snapdragon 810) though - that power hungry menace lagged pretty much everywhere where graphics were involved and discharged on QC 2.0 charger even when e.g. media scanning or playing Hill Climb Racing that worked fine on Moto Droid 4

I agree quick charge 3.0 is not that quick.

Things will be a lot better if the screen is off. I mean....DRASTICALLY .

Using a newer cable (had it for about a year, good condition, premium quality), it charges even with 100% backlight and power-hungry apps running. Not sure how fast though, it doesn't really matter to me while at work. It's not even QC 3.0, it's a year old Samsung Adaptive Fast Charger that's unofficially compatible with QC 2.0. Using the stock QC 3.0 charger with display off, the phone charges under 2 hrs.

Mind that the more the battery is charged the slower it's charging - advantage of QC is mainly in reviving a dead phone into a usable state. Otherwise it would cripple the battery capacity fast.

So, I am satisfied with my U11 and its charging performance

It's annoying they didn't implement QC 4.0 in the U11 for whatever reason but I have experienced the "check cable" message like twice. The HTC 10 did it too though unless I had a custom kernel and then it consistently worked. It's probably a kernel coding issue. It takes about 2 hours for my U11 to go from 1-100 and the battery temperature is much lower than the M7, M8, and 10 which all hit around 115-120F while charging. The U11 maxes out at 109F. I've yet to see it any higher.

So far the only device to have QC 4.0 is the Nubia Z17 (and its actually got the new QC 4+, not straight 4.0) - Qualcomm hasn't explained why there are no QC 4.0 devices on the market.

U11 has hard coded charge rate of 1A when the screen is on. Not sure why, temperature maybe? You'll see charge rates about 3x that with the screen off. 0-90% in ~1 hour.

Yeah...what he said! ??

Has anyone got a fix??.

Since October OTA update, which says August update. Fast charging is doing what the pixels did. Only fast charges with supplied charger. Any other fast charger does not work.
