Galaxy s4 battery problems

[hat]

I've had a galaxy s4 for a little while now and it has serious battery issues. It worked fine for a while (battery drained a little fast but whatever), until it stated randomly shutting down even though I still had like 40% battery left. So I ordered another battery on eBay, and all was fine for a while, but now it's shutting down a lot again. It'll shut down on me even though the phone reports like 75% battery. I've even tried flashing another ROM (cyanogen) to no avail. What's going on with this phone?

My dad has my old S4, still working fine with the first battery (although he still has a never used spare).
I never rooted the device and still works perfectly.
I'm no mobile phone expert but this is very annoying, would you be able to restore it to exactly as you got it from the shop or your provider?

Bad battery -- one of my Oppo Find 7 batteries does the same thing so i marked it with permanent marker and tossed it somewhere

Try original Samsung S4 battery?

 

[Komshija]

It might have bad or loose connection or something might be short-circuiting. That's my first opinion on that problem. Open and inspect the device. Clean battery connectors with alcohol, either isopropyl or standard "70%" alcohol.

I'd get a Hyperion extended battery and run another ROM, stock with touchjizz is a drain

Is it an original battery? Had the same problem with my 3 mos. old S4 battery that I bought online. Instantly shuts down at 30%. Still looking now for an original S4 battery, but finding it here in my country is such a headache. All I see are "oem" china branded replacement batteries.

ebay battery's are generally garbage actual OEM-Samsung battery's are nearly impossible to find in new condition you are better off with a reputable aftermarket most of the replacements on ebay are fakes

I have one of those in my spare s4 i use as a media device

I gave up on the s4 unless you have one that was LOKI'd they are effectively worthless as a daily

Not sure how I would be able to tell if it's an "original" battery or not. If it's a fake, someone did a decent job making it. Looks just like this one:

The battery I had in the first place works better than the replacement I bought. It doesn't last a whole day but at least I can use it for 30 minutes without it dying. My other battery looks a little swollen now... I know that's not a good sign. It was also a tight fit (even when I first got it) when the other battery I had fit just fine, but it didn't look swollen or anything... /shrug

Looks like I'll try an aftermarket battery this time.

It seems in my country it's all better regulated, less chance of buying a "fake" one.

This is the first thing I would check too. A loose connector can definitely causing the issues that you are having. The same happened to a friend of mine a couple of days ago, it was with a 1+1 tho.

I had an old S5230 from Samsung that had a similar problem, apparently the battery contacts weren't touching the battery firmly, so I had to stick a piece of paper between the battery and the casing, and that fixed the issue.

Same thing happened to both my parents S4 I just replaced there batteries with new OEM batteries and they are working fine again.

As stated, the battery is probably bad. My old Note II does the same because the battery is extremely swelled and completely toast. (Can't even fit the back cover on)

 

[cdawall]

I can't believe people still have working s4's. My wife's croaked on her 2 years ago and she actually does quite well with phones.

Go to a service location and buy one. They are still maintained made new.

anything that says samsung on it is fake samsung stopped making s4 batterys years ago the NOS is depleted

I've seen 2x S4s with a power button issue, where the button seems to get stuck in the depressed position and the phone refuses to stay on for long. Sometimes it looks like a boot loop, others it will work for 5 or 10 minutes then go off. I know one of these (the first I saw) the owner had gone through 2 aftermarket battery replacements and couldn't figure out why, turned out to be the button.

Back in the days when I had my S4 I used an Anker 2600mah battery. The quality was really good.

I can't believe people still have working s4's. My wife's croaked on her 2 years ago and she actually does quite well with phones.

I had mine until last year. It was actually pretty decent. Load up some custom ROMs and the phone felt really snappy. I had the international variant with the Exyon processor. When the wife decide to grab an iPhone7 upgrade I got her old iPhone6 to replace the S4.

The s4 works just fine for me as a phone, notwithstanding the battery issues...

what about flashing it with stock basic rom then test it again

The battery already sucked with the stock ROM, and there appeared to be a slight improvement with Cyanogen, probably due to less junk running in the background.
