Infinite charging under Windows

[Hans Sprungfeld]

I think the problem is, that this stupid tablet just uses 0.5A regardless of the cable or charger you use. That would also explain why it charges so damn slow. The power then wouldn’t be enough to power it, and it always drains a bit more from the batteries too, then it goes to 98-95% and it starts charging it again.

I suspect you are right.  I’ve actually never been able to keep mine charged while I’m using it on heavy load.  Even plugged in it drains.  The only way for me to get a full charge is to leave it on over night while the tablet is off.

The charger you guys are using are probably not able to push enough juice to the iWork 10. Mine can take in up to 5.14V 2.39A(around 2.2A-2.39A) with my Anker 60W Multiport USB charger which is the limit of the charger(5V 2.4A). On a side note, my tablet is powered off. When it’s on, it charges around 1.8A-2.1A.

Twice, you’re joking right. Or you cant read properly. I said, I tested several (good) chargers, including my original charger of my Dell Venue 8 Pro (2A), my original charger of my other 8″ tablet (2A) and my 40W multi 2.4A charger. None charges this tablet, the USB-c rev2, fast, and none can give enough power to power it while it is ON. Friend of mine who has also the rev2 (usb-c) has the same result. But I am using the cable which came with the tablet, so I don’t know if it’s a bad one and maybe the reason for it. You’re using it too though I guess.

I believe you didn’t specify the type/brand of charger you used, which was why I assumed that the charger that you’ve used was not outputting enough power to charge your tablet since you claimed that it charges only at 0.5A.

Quoted from your post “I think the problem is, that this stupid tablet just uses 0.5A regardless of the cable or charger you use. That would also explain why it charges so damn slow.” which is not the case for me, so I recommended you guys to try different charger but since the charger is not at fault here, have you tried other Type C cable? I tried the XiaoMi USB Type A to C cable and it is charging at the same speed as the stock cable at 2.2A-2.4A. My other iWork 10 Ultimate with the microUSB 3.0 port charges more slowly at only 1.8A even when it is turned off. I have another iWork 10 Ultimate Type C arriving next week from a different supplier. I will test that one out and see if there is any difference in charging speed.

You still don’t get it… the problem is not the “slow” charging. I am talking about the fact, when the tablet us turned on, the charging port cant keep it “on power”. Charge yours to 100% and then let it connect with your charger, turn it on, and play some hd video fullscreen or use some cpu intensive programs, like prime95 for example, then wait about 5 minutes. Youll notice that the battery begins to drain to about 95% and then it will charge and trigger an infinite charge, stop, charge, stop, charge, stop. It seems to be the charge logic is “bad programmed” or broken, because [email protected] should be enough to keep the tablet powered through A/C.

I get what you mean. I did a search in google and it seems more of a problem from windows side.  Seems like its pretty common

… I was glad if it wasn’t charging, you don’t get it, it is working normally. I also could reproduce it now too under Android, mostly a bit harder because Android draining less power I guess. Do what I told you, and do a stress test like prime95 or a similar app under Android, and youll see the power cant keep the drain. The battery will slowly fall to 95% and start charging stop charging stop.

The supplied cable is shit – mine fell apart pretty much straight out of the box.  Changing charger and not changing the cable limits your experimentation to one variable that you’re keeping constant.
