    My battery drains too fast, using my phone continually it can discharge in about 3 or 4 hours. I have installed FirstFlight N7 Themed V6 ROM, in the stock lollipop rom this also happened. I installed Ampere app to measure how much current my phone was charging and discharging and when the charger is not plugged in, it discharges at 460mA, is that normal? I bought a Samsung 2A charger and it charges at 600mA or maximum 700mA but I changed the usb cable of the charger and it charges at 860mA or maximum 900mA. I don't understand because it should charge at 1900mA, shouldn't it? how do I reach that? I need to mention that I charge the phone directly in a wall, not in a usb port, and why does my battery drain too fast? I need help. The model of my S4 is I9500

    Thank you! yes, I bought a new battery two months ago and there was a diference but not much, the old one discharged faster than this, I think the battery I bought is not an original one

    Ok -- sorry, but that's probably the most I can contribute to this thread, since I don't know the technicalities of charging rates, especially in the context of a custom ROM. Hopefully someone else has some good insight!

    Hi Ricardo, how fast does your phone charge?;since you say that your phone charges with 700ma and 600ma I think the charger does not charge it accurately. I use to have battery related issues before until I downloaded Ampere and found out that most chargers I bought were actually charging my phone with tiny bits of current. But changing my charger to one that chargers with 1000ma and 2000ma with the help of Ampere I don't suffer Battery related issues anymore.

    I'm not completely sure but it takes 3 or 4 hours approximately using the other usb cable, but charging with the one which charges at 700mA it can take even more. I'm starting to think the Samsung charger I bought is not a real 2 amp charger. Any idea why it discharges at 460mA? it looks to be too much current to be discharging at, or is it normal? really thank you!
