Alright. This has been bugging me for some time now. My cheapo Kyocera Air refuses to keep a steady charge on my bike. On a full charge, it lasts about 6h plugged in on my bike with GPS going. Less if I have BlueTooth enabled. I now own an S5 so I'm going to compare the two using both the app Ampere and a physical meter showing the charge rate. S5 plugged into the wall charges at about 850mA on the meter. Ampere topped out at 900mA. Kyocera plugged into the wall charges at about 650mA on the meter. Ampere was a little over 820mA. Oddly enough, running GPS and BlueTooth music going, the charge rate barely moved compared to all apps closed. I didn't notice a difference. So we have that both phones charge on the wall just fine. Enough to charge while apps are running. Great. Now onto the bike. S5 charges 1200mA with all apps going. 1880mA with no apps. Thing went up like 2% in a minute. Crazy fast. Kyocera instantly reads 460mA and drops to 80mA. Both Ampere and the meter read 80mA. So the S5 works the balls on the bike. Perfect. Charges at almost double than the wall. Kyocera is a freakin' brick on the bike. It'd take two weeks to charge on the bike from 0% battery. Why is that? I have the phone setup for charge only in the connection options. Can it tell it's D/C power? Here's a video I took of the setup: No idea what the issue is. Any help is appreciated. Thanks.
