I am completely at a loss as to why a software driver that simply points the OS at the cable should have anything to do with the power sent to that port?

Greetings everyone...

My K750i (R1A044) is recharging its battery on USB cable, but not fully... around 80%.

My past MPx200's battery can be fully recharged on USB cable (100%), on the same USB port on my PC.

So, I guess problem is not on the USB port but rather to K750i's hardware / firmware... or else the problem of the K750i's USB cable.

Regards,

I am using the USB lead supplied with the K750i at work and it is draining my phone instead of charging, it says charging when I first plug it in but after checking the power level keeps reducing, tested on all 3 of my work PCs

My phone charges ok on my home PC which is a USB hub built into my Monitor base.

This could be a problem if some USB ports don't work as I am getting an extendable USB lead for travelling, guess I will have to get a small travel charger too!


Mmmmm.........THAT I SURPRISE

my only concern with usb charging is that it doesn't overcharge the battery - that could actually reduce the batteries lifecycle. Lithium battery chargers never overcharge or trickle charge the battery since that shortens the life cycle of lithium batteries. The cable doesn't have any charging circuit built in.

I guess if the phone is capable of stopping the battery from being charged once it is topped up, then it should be okay, otherwise in the absence of more info, I am only leaving mine on the lead when I'm actually using it (that way it discharges as fast or faster than it charges - hence not overcharging the battery)

Hopefully I am wrong and the battery won't be overcharged no matter how long it is left on the cable. I also remember the dss-25 (old style port) - which is designed not to charge the phone when cradled - so if SE have designed the cable for the K750 to allow charging, then there is a good chance it's okay. I'm still playing it safe for now.

I'll try it again with the new firmware R1N035 and see if they have fixed it. Gotta wait till I get home though. I am carrying a retractable 3rd party USB cable in the office and apparently the SEUS program does not detect that as the original USB cable for the update.

Anyone else tried USB charging with the new firmware yet?

OK, I got R1N035 installed.
Plugged my phone into the USB cable.
Battery was at initally at 69%. Left it charging. Didn't keep track of how long (probably 1/2 hour later) when I checked again, battery level is now at 90%.

So, I think the new firmware fixes the issue of USB cable not charging the phone properly.

Anyone else can confirm this?

it seems at first that with new fw phone charge to 90% but after a while it starts to drop again, have anyone tried to charge it from 0% via usb?

Will try now for you, updated mine to R1N035 couple of night ago, the phone is on 76% now. Will reply when it has stopped



Im charging mine up now, with the battery at 66% now, will tell you how far it goes
