For what it's worth, you've done a great job taking the steps you've already tried . I just have one more suggestion. Can you test the phone in Safe mode to see if it charges faster? Please keep us posted on this.
I can't even get the phone to do safe mode. I push the power and down
volume at the same time and wait for the Samsung logo to pop up and let go
of the power button and still hold the volume down button and it just boots
up like normal. I've tried it 10 times and nothin. This is ridiculous. I've
been refraining from using my phone bease the battery drains faster then it
charges. It takes the majority of the day to charge it fully. Please tell
me there is something else that can be done.
Do you have any 3rd party battery saving apps installed? If so, you could try uninstalling those and testing out the battery life. If there's no physical damage to the phone and you have extended warranty, you may need a replacement phone. At this point, if safe mode isn't working, there's really not anything else you can do to get this resolved. Sorry about that, but you've done everything you can.
