Problem about strange battery behaviour

[Android Central Question]

Hi, everyone.. My story begins like this:
My previous battery on SG G850f was weak (original battery has 1860 mAh), but I could use it with no problem. I notice in July that when battery goes down to 3,4 %, signal (or network service.. I dont know how to tell that on English.. I mean straight lines that provide us ability to call someone ) dissapears suddenly and after few secunds my phone turned off. After few days, my phone suddenly shut down at maybe 10 % and became very hot. i opened it, and MY BATTERY BECAME BULGED as it want to explode...
I bought a new BATTERY, and I have similar problem... It shut down on even 60% (sometimes, it turn off at 30%, 40%)... Also, battery charge period is very SHORT (one hour is needed for charging to 100% - that is IMPOSIBLE!!! HOW!!) Also, drainig of battery is very fast (it`s empty after less then a hour)... Please help me. What should I do? I forget to tell that I have problem with lamp on my phone.Shortly before my first battery die, I noticed that lamp sometimes doesnt want to light. It needs to restart.

First, go to settings and battery and see what is using your battery so much. Post a screenshot. Then clear the cache partition and reboot. Check all your settings, paying attention to your unneeded bt, wifi and GPS being on unnecessarily. Good luck.

Okay. Now you'll need to wait and see until the battery stats starts putting out the data

Applications are not the problem. My previous battery could stay all day nearly with same apps.. Today, I noticed my phone began to shut down even at 90 and more %.. I am very nervous
