I have already fast charging disabled. However there's something I noticed. The drain of the S7 on my 9000mah powerbank is staggering. It drained 28% of the bank to charge up around 13%. That 28% is already nearly 2520mah, converted to 468mah. In comparison, my Galaxy V (1500mah full capacity) goes from 5% to 100% on 20-25% of my bank (1800-2250mah), and my Note 2 (3100mah full capacity) goes from 50-100% with about the same 20-25% from my bank. I wondered if the bank was broke, so I tested it on my Galaxy V and Galaxy Tab (4000mah) to charge, and I'm getting the same projected rate of an additional 500-700mah lost on top of the actual capacity needed for heat or electrical transfer. The 7 Edge is killing the bank. As of typing this though, I realized I was using the power bank supplied cable, and haven't tried the supplied cable on the S7, or my Silvertec cable. So I will be trying both later. and see if there is any difference. I'm starting to not like this fast charge tech.
