Hi all,
I have a Samsung s4 GT i9505 and when i leave it for charge the charger gets very very hot and im not sure on what to do. I only bought the phone yesterday ( 22/07/14) so it was only my first night with it. I decided to switch off the phone and leave it on charge, but that made no difference. I installed all the OTA updates yesterday as well.
Any help would be appreciated. Many thanks

I have the same problem with my s4. I guess it is normal for a samsung devices, because I heard from other people having this problem on a s3 or s2
Same here, as long as it doesnt shut down its np, the charger for s4 provides 2A which makes it warm while charging

It is not a problem. The battery gets warmer because samsung charger gives more "juice" than most other chargers. The battery needs more power to charge because the phone uses it more, so the battery heats up more. Also, it charges faster...
The higher the charger current (2A), the faster the charge rate, but also, more heat!
Guys my charger isnt a 2A charger, I got a 1A travel adaptor.
Input 100-240V 50-60Hz 0.15A
Output 5.0V 1.0A
But it runs incredibly hot when i leave it for a charge.

If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Are you using the OEM charger?

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)
I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

Yeah I was charging my phone earlier using a car was adapter with the oem micro usb cable and they phone got very hot.
What do you guys think? Is this a cause for concern? Do I need to buy a manufacturer approved adapter?
Is it safe to leave the phone plugged in overnight? I usually charge the phone when I go to bed, but I've the this might damage some batteries.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..
It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)
I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.
I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:

My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
Hello all!
I recently bought an i337m S4, and I've got a few chargers around from older phones. I have two that are 0.7A. I'm wondering if it will do any harm to the battery to be charging it at a slower rate? I usually plug my phone in at night, so I was thinking it would be fine to use the 0.7A charger overnight and use the faster 2A charger that came with the phone when I'm on the go and need to charge faster.
So, is it OK to use the slower charger and not harm my battery?
Thanks a lot!
I always use charger that came with the phone. If you want it to charge slower just plug it into a usb port.

No it won't hurt. I use a .7A at work all the time. However it doesn't charge while using the phone so I let it sit and it charges fine.

Alright, thanks a lot! I'll go ahead and use it to charge overnight.
Hi, so.. I forgot my charger at work.. and everyone around me use iphones and I have to charge my phone
I found an old samsung galaxy 1 charger, and so far it's charging pretty good..
but I want to make sure that it's safe. do you guys know if using a samsung charger can do any damage to my battery?
I also have dorimanx kernel forcing fast charge mode.
thanks in advance.

Nope, it's fine. It might charge slower, but the voltage will be the same. A non-android compatible charger will only charge at 500mAh due to the way Android determines USB vs AC charging, that's really the only difference you'll ever see on such a charger beyond the capacity of the charger itself, which would just manifest itself as slower charging.
Hi all been searching but no real answer can you use a s7 fast charger plug on a Samsung s8?
Of course. Why would would you think you couldn't?
Voltage but was not 100% sure that's why I thought i would ask.

Pretty sure it wouldn't be an issue! I actually used the samsung charger from my S8 to charge my HTC 10 last night and it took surprisingly long to charge! Out of interest i then decided to charge my S8 using my HTC charger and the HTC charger charges it faster then the one supplied by Samsung! Maybe Samsung are being cautious with the fast charging capabilities since the Note 7 dilemma! Who knows. . . . . . . . . I just found it interesting that the Samsung fast charger (whilst it is pretty quick i guess) but doesn't compare to my HTC fast charger!
Samsung fast charger charges 3000mah battery from 0 - 100 in 1hr40mins
HTC fast charger charges 3200mah battery from 0 - 100 in 1hr 20mins
I was using my old S6 charger all week, no issues.
I believe they're all using the same 15W charger. Samsung has not revised the charging power since S6.
Using s8 fast charger it is rated as 5v , 2a im worried as is dont have lg original charger which supports 1.8a(fastcharge). My phone also got hot on samsung adapter . Should i buy original or its nothing to worry about. Kindly need advice.
AFAIK, there will be no difference. The chip controls how much energy is delivered to the battery, and even if you use a 3a charger, the phone itself will limit the maximum energy delivered so it doesn't affect battery.
It's normal that the battery gets hot on fast charge (even in normal charge) Just try to avoid using the phone or charging in a hot environment so the battery doesn't go further than ~40°C more or less.

The original one is 9V 1.8A so there won't be any problems with the Samsung one.
