We have come a little bit Closer
So using Modified AndroPlus Kernel v63 and sysmon.cfg edited by Jackos (rev4) the devices charges again faster.
Using the YZX Studio Power Monitor
i can see the QuickCharge2.0 working at 9V (img
) we can also see the charger drawing about 8.8W (img
) the Charger is supported up to 15W, now we're trying to pump these into our Z2
As you can see in the Picture the Charger provides 8.8W in 9.1V and 0.97A, in the phone this will be converted into the charging Voltage (which should be around 4.3 or 4.5V... no idea.... really) Let's assume it's 4.5V so 8.8W would be 1950mA, Ampere saying "charging with 1690mA" would mean the device is currently using 260mA which might very well be true.
The YZX Studios Power Monitor does have a Log feature (firmware 2.5 needed) if you connect it to a Computer via Serial or Bluetooth. I haven't done this yet, will certainly in the near future, therefore all Stats shown in the Excel Graph are made by internal Log via the BatteryLog App
Voltage= Battery Voltage and NOT charging Voltage!
Fully charged, how much can we fill in our Battery?
14.5Wh we need to charge our Battery, theoretical 3200mAh x 3.8V would be 12.16Wh, so we lose about 2.34Wh due to charging inefficiency.
Wall of Text over... let's get to the Results!
130 Minutes for a full load... from 1% as you can see in the graph the battery voltage was dangerously low, below 3.5V
(That's exactly why you should NEVER use your phone under 5% Battery if anyhow possible! Not healthy.... not healthy at all)
You can also see the battery Temperature droping after 75% / 80 Minutes, if i would have the input current, most likely that would also drop right then.
i have absolutly no idea what that crazy spike at 22 Minutes is.... and ideas are welcome ^^ I did not use the phone during charging, but i did see 6 updates were done when i came back.
So yeah... this is nowhere near the Qualcomm's claimed 60% Charged in 30 Minutes (took 60 Minutes) but this is still the fastest charge ever achieved on a Sony Xperia Z2 International.
