s4 lose battery when unplugging.

Hi!
My galaxy s4 drops about 6-8% battery when i unplug it from the charger. The first 10-20% of battery drops pretty fast aswell.

Perhaps the battery is failing, or perhaps the battery charge meter is inaccurate.

You can't judge much about battery usage after such a short time as in your second screenshot. There would in fact be something wrong if the reading for Screen were not high after such a short time. But even with normal use after several hours, Screen will almost always show the highest battery drain.

If the screen is on a lot, it's going to use a lot of battery.

Press the graph at the top of that screen (Battery) and screenshot the next screen. The Awake line at the bottom (and the signal lines) will tell us a few things.

Also, when the phone is fully charged, unplug it and let it sit for 5 minutes. Then charge it again until it's fully charged.

If you keep using the battery until it's almost fully discharged, before rcharging it, it could be pretty well shot by now. You shouldn't let it get below 40% before charging it.

I often use the battery until it's almost fully drained, so if i get a new battery i will try to have that in my mind. I took two new screenshots, the screen have dropped a lot trought the day.

As I said, if you've been doing that long enough, the battery may have taken a long walk of a short pier already. Discharging to 0 can give you 300 charge cycles, which, if done only once a day, is less than a year. (A properly cared for battery lasts for years. I still use some 10 year old lithiums.)

There is nothing wrong with your system nor your phone.
The battery is getting old and tired bro.
