Using a New Trent External charger I noticed that the phone was still losing power, just at a way slower rate than without it charging. Phone showed charging. I was using netflix via 3g at the time. Would this be expected? Not super worried as the battery charges just fine when screen is off and not in use.

How many amp output is that charger??

My phone can't keep up with the charge if I'm veiwing a movie using HDMI unless I run incredible kernel with fastcharge enabled.

7000mAh. Think 1V output?

IIRC, the stock A/C charger is 1 amp.

A lot of aftermarket chargers do not have the balls to charge the Rezound.

you may need to modify a usb cable to short the Data wires to get the full charging potential out of it.

or try one of these cables from amazon:

Does this cable work for sure with the rezound??

I don't need it right now with the incredicontrol running, but I ordered it just as a handy thing to have.

My new Trent works pretty well, but I wouldn't expect it to keep up with streaming vids. I found that it gives a charge to the idle phone at about 800mA, which is about the same as the stock wall charger.

Pick up battery monitor widget and you can track your plus and minus usage pretty well to decide if everything seems OK.

Well, I'll answer my own question. The cable definitely DOES NOT force higher charging at least when using an HDMI adaptor.

If I use Incredikernel with fast charging enabled with Incredicontrol, it will actually GAIN charge while playing a full length movie through HDMI.

This morning, I flashed back to dsb 1.3 with no frills cpu control & hooked up the new cable for charging. I started with a 100% charged battery & after playing a 1 hour DVD RIP from my card, it was down to 89% charged. Using Incredicontrol, during the exact same test the battery still read 100% at the end.

Thanks for your results jmorton10. Good to know. I wonder if it's the connections inside the HDMI adapter messing with it.


Not sure why HTC can't just get this right to always pull the max possible from whatever it's hooked into!

My understanding is because the MHL adapter needs the USB data pins to work properly and they can't be shorted out as mentioned above, the phone thinks it's on a USB connection and limits it's current draw to 500mA.

That is definitely the problem, the battery monitor widget claims it is charging from USB even though it is plugged directly into an A/C charger.

I guess I will be flashing back to Incredikernel/Incredicontrol tonight. I do like dsb kernel slightly better as it never freezes/bootloops etc. ever on that kernel. It does stop responding occasionally on IC (requiring a battery pull) although it doesn't happen very often.
