    I will point out that this is not a WP issue. I have a Nexus 5 as my daily driver and this phone charges much slower with the LG data cable it came with compared to a charge-only cable I got with my TYTL power pack.

    I have had several Garmin handheld GPS units starting maybe 15 years ago. Small B&W screen, a whopping 1.44mb - yes, mb - of memory to download a few maps into. Via some Garmin SW I could do turn to turn and real time on a big color display...........on my laptop on the passenger seat! Now all this and so much more in the palm of my hand. My point: a set of 4 AA's will run the thing, screen on, for about 35 hours!

    So, why can't our cell phones do that? I have NO idea, and I've been "into" electronics all of my long life. My Android also heated up and gobbled up battery life.

    I took a 35 minute walk the other day using Hike and Bike, a real nice app. My Battery Sense app shows that I was sucking 33% per hour! This is compared to about 3% when on standby, Wifi, Cortana, 4G, Glance always on.

    Tis a mystery.

    I promised I'd post back after I got the cable. It didn't arrive until yesterday, and in testing today on my (previously mentioned Griffin) charger, I was finally able to successfully charge my 920 while navigating. Looks like most phones need more than 500mA (I saw lots of Galaxy S 3/4 complaints online), but my old GNex was fine, so I didn't notice this until I got my 920. Yay PortaPow cable.

    So I got a new 925 - see another post - and I plugged the USB/micro plug into a front USB port on my PC. Started charging, no surprise. After awhile, I noticed it wasn't. The phone charges fine from either the micro USB data type connection or the wall charger.

    Apparently is was some kind of safety built into the circuit, it works fine again today.

    Here's something indicating this thread is on the right track. My Battery Sense app shows that when last plugged in, it was the wall charger, it started at 48%, was at 100% in 59 minutes! This is a 2000mah battery, ergo, charged 1000mah (1 amp/hour) in one hour. The wall charger is rated at 5V, 1.3A out. Since charging involves losses, i.e., you waste some electricity due to inefficiencies, I'd say this all makes sense.

    I remain skeptical that a micro USB is good for having 2 amps pushed through it, but I guess Nokia is certainly OK with 1.3.
