From full discharge to full recharge, my line never skips a beat.
Full discharge is how I reset my battery. I "forced" my battery to remain active until my phone no longer turned on. From that point, I decided to test another bit of knowledge that I know from my r/c car days...
When I prepped my r/c car for race day, the lap events lasted a total of 3 mins. With my ni-cads, I would quick charge them for a timed 7 mins. This cycle is known as a quick charge/quick dump event. I need the maximum amount of electrons for a full 3 mins worth of work. BUT for practice, I had a separate cell set that I charged for an hour, that gave me roughly 14 mins of electrons.
I said all that to say this: A wall charge has a recharge voltage of roughly 5 volts dc. Let this forever be known in our device lexicon as a fast charge. Wall charge = fast charge/fast dump. In this state, most of us leave our phones "on".
For this test, because my battery dumped and my phone wouldn't turn on, I left it off while recharging on my laptops usb output. This source of electrons has an output of roughly 2.5 volts. HALF of the wall chargers stepdown transformer output voltage. It took maybe 3hrs to recharge at this rate, but once that green "fully charged" light appeared, I disconnected my phone and turned it "on".
Look at the series of images for results...
With my stardard apps running, wifi on, basically the way I've always used my phone. I've neared the 12hr mark at 72% battery reserved :D
