Help Galaxy S4 Battery Draining Fast

[MichelleC38]

I'm not sure if I have the right forum. My phone is the S4 Active but I couldn't find the right thread.

Not too long ago I posted about my phone not charging. I dropped it and I would plug it in, but the battery wouldnt charge, it would drain. Even though the charge icon was there. Ended up buying a new battery. Didn't work. Was switching between my old S4 to charge the battery and put it back in this one. All of a sudden, my old S4 stopped charging as well. I thought the Active was done for.. so I bought a different phone, which literally got stolen a few days ago. So instead of throwing out lots of cash, went on ebay and bought a USB Charger Port. I previously took the phone to a repair place to fix and the guy said it wasn't fixable and the new USB charger port wasn't fitting properly. Well, I did it myself yesterday. Charges fine but slow.

Now I'm noticing the battery is draining fast. It was dead for a few weeks. Completely drained. So I let it charge.. no problems, right? I let it charge to 100% last night.. been on my phone for maybe 5 minutes this morning and it's down to 93%. I've lowered all settings, turned off sync, factory reset, tried multiple chargers, Uninstaller unnecessary apps. Nothing is helping. Battery shows a screen is using 51% while the OS is using about 19%. Phone fell pretty hard. Not sure what's going on.. but I'm out of ideas. Possibly get a new battery, or possibly something in the phone that is broke that is causing it to drain??

Everything works perfectly like it's brand new, except the battery drain and slow charge.

Edit - It seems that the battery I bought is a cheap battery. Not the Samsung battery I originally had. I'm not sure if that could be an issue.. but I'm going to try charging the old battery and see if I have the same issue.

It could be a bad battery. I would buy a Samsung battery for it and not a after market one. Hopefully you'll get this figured out.

Here's a good link to help identify FAKE S4 batteries. http://www.************.com/blog/identify-original-fake-cellphone-battery/
Can't get the link to show and work properly - but Google 'Fake S4 batteries' and it's the ETrade site that gives an excellent description.

A good battery would remain at 100% for a while after you disconnected the charger. If the battery loses charge immediately it's time to replace.

Nearly all the batteries I've charged either in phone or external charger will indicate 100% charge, but when put into service will show immediate drop of charge to 97-98% dependent on amount of work you do. If they constantly drop down - there is either a fault or old age catching up with battery.

Might be a defective piece !! Did you try disabling the apps running in the background ? They use a lot of battery power, also the screen saver and 3D wallpaper. There might be many reasons for the battery to drain faster, try following those tips and see if it works.
