Can a non oem car charger kill battery?

i bought this car charger from ebay from my vibrant for 10 bux. when i went to canada this was like 3 weeks ago and since i got back my battery life was never the same it dies pretty quick. what can cause this

I would avoid the cheap generic chargers. Go with the T-Mobile or Samsung OE car chargers. Purchase a new battery if you think it's the source, they're pretty cheap on eBay.

I don't think the charger did that. I have made some Frankenstein chargers that have never affected the battery. I would guess the charge controller in the phone crapped out, but not because of the non OEM charger.
The thing you plug into the wall or cigarette lighter doesn't know or care about what phone or battery you have. it just gives the power. it doesn't tell the phone to give you the "UNPLUG YOUR PHONE" message, the controller in the phone does that.
Go to powerstream.com for info on cells, batteries, and charging.
Think about this...if you have your phone plugged into your car BEFORE you start it, what happens? The charger goes dead, then comes back. That is way more stressful on ANY charger.

Off-topic, but it is bad on the battery to leave the phone plugged in all night, with the phone asleep but not off (i.e., the phone remains plugged in long after it finished recharging)? I do this, as I suspect many others do... I was under the impression that the phone cuts the cycle so there's no "overcharge" issue. Thanks.

chargers shouldn'ty hurt your battery. I've NEVER owned a OEM car charger in my life, and you know now that i think about it I think the crappy $12.00 charger in my car is the same one I bought for my Razor back in 2005, I've used it for my Jasjar, N95, my Gf's chocolate, her Blackberry and now my Vibrant no issues.
as for overcharging, phones like most electronics, should have a built in switch that switches to trickle charge after completion. also batteries no longer use memory Cell technology so again no issues there. I only charge my phones at night and I leave them all night no issues. no dead batteries, no exploding phones, no overheating etc.

Micro usb port/charging issues

Ok so i have been experiencing some odd issues with my micro usb port, started one morning i awoke to find my phone dead(had plenty of battery for the night) and it would not take a charge from any of my chargers wall/usb/car. After messing with it for a hour or so i got it to take a charge from one of my 6 wall chargers, it would not charge from a regular car charger or usb at that point. As the day progressed it finally started charging on usb/wall chargers but not a car charger. It also would say its charging when i would unplug the cable, animation and everything, it would take many reboots to stop that. Since this happened(week ago) i have flashed just about every rom/kernel combo trying to pinpoint the issue to no avail. The issue happened again this morning, wouldnt charge, then when it did i unplugged it and it was still showing it charging, also it said fully charged at 85% and the screen was doing this crazy flicker while plugged in..anyway im pretty sure the micro usb port itself is taco'd, anyone else experience these symptoms or have problems with usb port? from the little info ive found they are pretty bomb proof on the ns....

tuff out there on them streets today

My sons phone started doing the exact same thing yesterday, tho his is not a Nexus S it had the same exact symptoms. Went to Tmo for a warranty replacement and will be here tomorrow. Definitely a messed up USB/charging port.

[Q] Adaptive Fast Charger

Hey guys,
I was charging my note 4 with the adaptive fast charging today, and when I reached about 73% it stopped charging. The brick (plug) was bricked. Did not show any charging, thought it was my cable so i changed the cable around, but no success so I used a different charger (non adaptive fast charger) to charge it, which did work.
Upon discovering this I contacted Samsung and was told that non of my retail stores had any replacements in stock. Now i must wait for them to get a shipment of the order.
My questions are:
1. What could have caused this? My charger is only less than 2 months old.
2. Would using alternative chargers harm the battery or the phone?
Thanks in advance

Firstly, this should have been posted in the Galaxy Note 4 Q&A, Help & Troubleshooting forum.
Answers to your question:
1. Could be anything, from faulty charger out of the box but was working for a bit, to bad power socket, to lightning strike.
2. Using alternative charger won't harm your phone or battery. Maybe just untick Fast Charging when using other chargers.

Same issue

I had the same issue..the fast charger just wont charge my Note 4. Got the adapter and cable replaced. They didnt hve it in stock, had to wait a week. ..used the normal charger till them. Normal charger did its job, but took bit longer compared to the fast charger.

burning car charger, Note 4
I just purchased my Note 4, swapped out my sim and then connected it to my Belkin cigarette lighter/USB car charger.
5 minutes later travelling down a freeway ,when smoke started to pour out. I yanked out the chord and
still managed to burn myself with it. 2 weeks later I really needed to charge my phone while camping
thinking/hoping it was my old chargers fault. I also turned off fast charge and it blew my car's fuses and it got
super hot again within seconds. Is this normal. Do I need to know which USB's I can use and where?
Or is my phone busted?

just use a wireless qi charger. it avoids all these issues and no wires to worry about.
fast charging is bad for your phone and battery anyway.

So I cant charge my phone while I drive?

just get a wireless qi car charger cradle.

Has anybody used one of these?
Before I buy one I was wandering if anyone has used one and if its any good?

Wireless charging can't get to 100%

I have the Samsung official wireless charger that I got with my S7 Edge. Was using it on the S8 fine for a couple days when all of a sudden it won't charge to 100%. Day one it stopped at 84% and this morning it wouldn't go past 76%. The phone is pretty hot when I pick it up and the LED is lit yellow the whole time indicating it's being charged. Did a search on here and it seems like some people are having some problems with wireless charging but not exactly the same as me. Anyone else have this issue?

are you using the original samsung charger plug that came with the phone?

No, it's the original micro USB fast charge plug and wire that came with the S7 wireless charger.
This one
http://www.samsung.com/us/mobile/mo...charging-stand-black-sapphire-ep-ng930tbugus/

Im using a QI dock myself. Works fine here. 100%
Now I do remember some of the Samsung ones from the S7 were able to support the "Quick Charging" function. Which was designed to get it super fast to "x" % then switch to normal charging. So its possible your issue is something related to this.

It's weird because it would just stop at a random number. Even taking it off and rebooting then recharging doesn't help.

I remember reading on the Chip Binning thread about some people talking about bad chip bins causing battery problems and you may wish to consider getting that exchanged.

Well last night it stopped at 87% so in half sleep rage I took off my case and had the bare phone on the charger. Later on it was at 100%. I also have my work keycard in the back of the case which I'm not sure if that makes a difference because I had it in the case of my V10 and S7 Edge and they were able to charge to 100% with the card and case between the phone no problem. The case is just a regular thin case from eBay. Also pretty strange that it would stop at a random number. Gonna do some more testing tonight.

I use a thin gell tpu case on mine, I have a Mikobox QI dock as well.
Now stuff behind the case, that "could" maybe mess with wireless charging. Never tried with stuff inside my case.

I have had this problem too. Wireless charging stopping at a certain percentage.
Worst this morning as I woke up to 8 hours on charge and it was only at 56% still saying it was wireless charging!
Thinking about trying the official Galaxy S8 wireless charger

I'm using the samsung fast wireless charger that i bought from when i had my s6 edge+
I'm using a tpu case on the phone, works perfectly fine
fast charge doesn't work without the genuine samsung charger plug however

Had my regular rubber thin case on with the card inside last night and it charged to 100%. Really don't know what's going on here anymore. ¯\_(ツ)_/¯

Try an old lower amp wall wart with the non Samsung wireless charging platform. You will not have fast charge, but it will go to 100 percent.

Same issue here. It used to work absolutely fine and got to 100% every evening. Now it stops around the same amount every night. 80% ish
I have only noticed this since the last OTA update and its a nightmare. The phone is super hot and showing as charging wirelessly but it isnt. One thing I did try was to let the phone cool down and turned off "fast" charging wireless. Only when the phone had cooled down did it start to tot up again.
I have also had the odd warning saying that it wont charge any further until the battery cools down, which makes me think this is a "safety feature" that was implemented with the latest OTA rather than a fault, but not all of the time. It seems the message will pop up and then go away quite quickly (probably as to read the message I am knocking the phone off the "sweet spot" that charges it, so it doesn't feel the need to show me the message anymore)
Try letting the phone cool and then put it back on and see if the numbers rise everyone and maybe we can workout together what the problem is. That's my thoughts so far s that the phone is charging fine, heats up too much, stops charging, cools down, starts charging again, heats up etc etc.

Guess the end result of the story is. The S8 doesnt like to be "Quick Charged" via QI pads with the higher volts.

but it isn't, because a lot of people have fast wireless charging working just fine?

Update on my last post. I have fast charging off and last night I popped it on the charger when going to bed. Woke up about 4am to use the little bits room and there it was stuck on 81% as usual and very warm. Took it off the charger and went back to sleep. Woke up again about 7:30 and the phone had cooled down so put it back on the charger. By 9:45 the phone was at 100%. Looks to me like it is a heating up issue on mine anyway.

I get the problem too, the wireless charge of the original s8 package and use the skin case, when the first charge only up to 84%, after being released and cooled for a while then in charge again can finally be 100%, the possibility of problems in excess heat due to wearing a skin case or indeed a problem from Wireless charger, I do not know yet

Got the same problem here!
until now (about 2 months) im using allmost only Wireless charging (original samsung charger and cable)
untill today the Phone stop at 80% and its says that it still charging.. i took the phone of from the charger for about 30 second and put it back on charge and it charging ok...

Same problem. S8+ Exynos.
I'm using the wireless charger from the starter kit. Wired charging is fine and takes about 1.5+ hours from 5% to 100%. With wireless charging, the estimate is usually 2.5 hours but it stops at 80+% after about that time. Charging continues if I remove the phone and place it back on the charging dock after a few seconds. Having a case doesn't seem to matter.
Just now, it finished charging wirelessly with the phone off. It went to 100% but took 3 hours. I did check after 2.5 hours and it was at 83%. I didn't remove the phone from the dock.

ok so i've had this phone since 20/04/17
it's been perfect charging, until this morning
was quite warm, and stuck at 83% - had been at that level for a couple of hours....
weird
i had fast wireless charging disabled in settings>advanced>accessories - yet when i put the phone back onto the charger it said 'fast wireless charging'
i enabled it, put it back on charger. fast wireless charging again..
disabled it again, put it back on charger.. still said fast wireless charging !!!
so i enabled it again, put it back on the charger, went back to sleep for an hour and then it was at 100%
will keep an eye on how it goes the next few days

did you disable fast wirelss charging in your settings menu?
my theory being that if that were disabled, but still somehow fast wireless charging, maybe the fan wasn't on but it was still fast charging = excess heat?

normal charge OK, fast charge won't work

Got a new H918, however when I use the fast charger it was supplied with the phone only charges for a short amount of time (5-10 minutes) then stops. After that, it slowly begins discharging all the while the charging icon on the battery symbol is displayed.
I had it plugged in overnight, checked cables... even bought a brand new genuine charger and cable and that made no difference either.
However when I use my four year old charger for the LG G Pad (still 1.8A but only 5V, no 9V support) it slowly charges to 100% as normal.
Tried a couple of other chargers, they all charge the battery slowly up to 100% as you'd expect. Fast chargers (Samsung or LG) on the other hand stop after 5-10 minutes as I said above.

Thank you for the quick reply. I'd like to be sure if it's the battery, the phone's hardware or its software.
I find it strange how the battery is fine when plugged into an old charger, but won't work with fast chargers at all.
Have you had the very same experience, or was your battery dead irrespective of the charging unit?

Mine would show charged, then pop up a msg saying invalid battery and shut down the phone. Battery suggestion was the easiest and least expensive option to troubleshoot your problem. Of course if the phone is under warranty I'd send it in.

I'd like to report back, in case someone else happens to stumble upon the very same problem.
Got a new genuine battery off ebay and replaced the one I got with the phone. It worked straight away - managed to (fast) charge it using the original charger from 0% all the way up to max.
What a relief! Thank you again for pointing me in the right direction @cnjax.
