Charger - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys,
1 short question. Do I have to use original galaxy s4 charger or can I use another model from old galaxy s1 ?
It has 1A loading and loads longer but my point is - can it damage my phone by having too litlle current ? As I know the original charger is 2.1A
On the other hand I also use USB port to load my phone and as far as I know it has 0.5 A and loading takes a lot but I don't mind. The question is - is it safe ?

Too less can never do wrong, too much can though.
Me Gusta!

I read an opinion that too little power of charging isn't able to charge the batter to its full and because of that damaging it, but I don't know if it's true.
How about the memory effect ? When I charge with usb port and use the phone at the same time the battery is discharging even though connected. Isn't it harmful for the battery ?

Anything above 600-700ma should be fine, according to the link below for an 2600mah battery at 0.2c is 520ma so give it a bit more for safety, 1000ma should be fine, though the S4 will charge a lot slower.

EDIT : also the usb port on an notebook is only 500ma, and the S4 charges on that as far as i know, i don't have one to be certain.

Yesy my S4 charges on USB but my questions is : does it do any harm to battery ?
And another point : how about using the phone while charging it with too little current ? I have it when charging on USB, the phone just dicharges while I use it. When I let it alone it continues to charge (% going slowly up) , when I turn it back on it discharges again (the % going slowly down) - does it harm the battery ?

Actually a lower slow charge is better for the battery, as a fast charge causes the battery to heat up and heat causes damage to lithium battery`s
So good information on lithium battery care.

[B]Xperia X1 Recharging time[/B]

hey everyone , i am having a problem my first recharge session for the xperia when the batter was fully drained was about 9 hours? is this normal ? for the first couple of times , i am recharging my phone through the usb cable from my computer directly ?
Please Advise
I've never charged mine through my computer, only synced. I will say it took very long to charge at first. I'd recommend using the wall charger and charging every night instead of letting it drain all the way.
Wall charger is the best choice, unless u have got a battery charger & patience to take off & put on the battery cover every time.
I doubt whether it is necessary to charge x1 every night?
I also find that using a wall charger gives a much quicker charge time and to my eyes a longer lasting charge... I only charge when it gets down to 20-40% so it could last as long as 4 days... (usually 2)
wallcharger takes about 2 hours till its full.
USB however takes far longer. not sure why but i guess the ma/h used for USB is probably far lower then a wallcharger
Yes, USB charging is slower than normal charging as the USB port can provide max 500 mAh, my old K800i on usb charging can arrive max 92% even after 6 hours connected, while on wall charging it is full in less than 2 hours.
And regarding this question, i have another question:
Will usb charging work with any usb wall charger? i leave the wall charger at home, and at work i use USB charging, but a co-worker has a motorola phone with a wall USB charging charger, can i use it safely on my Xperia?

Yes, if you check that Motorola output parameters are the same of our SE wall charger.
Thanks
Guys i did charge it from the wall charger and it took less then an hour to charge the remaining 50% which is great guessing so its going to take around 2 hours to full charge it from zero , , thanks for the help
I've got a split cable (two usb ports into one) that came with a portable USB HDD. It works faster when charging off USB.
also if you want faster charge time then make sure the X1 is switched off completely.
recharging ... Saving the battery
what i understand the the slower you charge the battery the longer the battery life ;it could stay with you for more then a year with good battery life
on the other hand quick charging the battery will decrease the overall age of battery you are going to change it with in a year or two
i am not sure of this info for cellphone batteries but 100% sure regarding the laptop lithium batteries
please correct me if i am wrong

As far as I know, the asnwer is yes for the first part. The slower the charging time, the longer the battery will last (theorically).
But, the time horizon is not 1-2 years. It is actually longer than that, 2-3 years for cellphones and 4-5 for laptop (own an HP from June 2005, still getting 3h of battery life out of it!).
There are lots of conditions that affect the life of a battery, check out at http://www.batteryuniversity.com/ for more info (that's a real useful site, up to me!)

Hmmm... great idea man... but I am wondering if it could affect the battery. Which is the total mah supplied?! is it less than the wall charger one? that info could definitively chamge my mind about the split cable
1) USB charge is way slower
2) Wall is about 2 -3 hrs
3) GSM plus average usage, 1.5 days of use
4) 3G plus average usage 1 days
what my laptop battery care program does to prolong live is that it maintains a max 80% charge. perhaps this is same for all battery?
[email protected] thanks for the update , tell me what your going to do .. fast charge or slow charge?

Sincerely, it doesn't matter for me. 4 year is way too long and I never had a phone for that period, so I really do not care about it. The only thing I pay attention is to always fully charge and discharge the battery, every time.
Consider that the first bound to a battery life is its recharge cycles. Probably 90% of batteries dies/loose power because of too many charge/discharge cycles, the 10% left for other reasons (fast charge, totally drained power, heat, etc.)

the website doesn't say much about Lithium-Polymer batteries as opposed to Lithium-Ion which is all over the site. Li-Poly is what Xperia is using. I think you shouldn't overheat the battery when charging because heat will drasticaly degrade the battery life.
Yeh
Yeh, as a note to some former replied.
Li-Po (Lithium Polymer) batteries need to be kept in check, overheating can make them dangerous and explosive as well as reducing their life cycle.
Which point you charge the battery from with Li-Po does not mattery as long as the correct "conditioning" cycles are completed when new.
Also, as a note, I have once or twice attempted to charge my Xperia from the USB port on my laptop(plugged in) over night, only to find the battery of the Xperia was totally dead the next morning.
The USB ports of my laptop provide 500mA (standard) and the charger for the Xperia is 700mA so not a significant difference, but I guess other things affect the the USB ports on laptop (including Windows 7 having the ability to disable US ports to "save power").
It most probably assume the "device" connected is wasting power and so disables it. Although we want it to charge. Same goes for Windows Vista. This option can be disabled though.

Yes, but wall charging while using connected wifi does heat the battery relatively quickly (my Polaris, Li ion, gets vaguely warm, not as obviously heated as the X1 battery)
I've tested this with a new replacement battery - careful overnight charging when new - and similar behaviour still results
This has convinced me that the X1 has a serious weakness, as charging while wifi connected is a long-standing work habit. If the wifi is connected without charging, a usable time of 2-3 hours is all you get (no good )

Warm Battery when charging with AC adapter

If this was mentioned before I'm sorry about bringing it up again but with my lack of knowledge on li-ion batteries I figured I'd check with you guys to make sure nothing is amiss here. When I was charging my n1 I noticed the back getting quite warm so I installed spare parts and saw that my battery temp was nearly 38 degrees Celsius.
Is this a bad thing or is it completely normal and I shouldn't think to much of it?
Again I'm sorry for the noob question.
Completely normal.
its normal, the wall charger charges at 1A, while USB charges at 500mA. If you want a faster charge wall charging is the way to go. I use USB because im not in a hurry and high temps are not good for any device (although im not saying you shouldnt use a wall charger, its just my personal preference).
It's normal, mine behaves the same way...

Actually, the battery is designed to be charged optimally at .98 amps. I recall someone saying that charging with the adapter is better for battery life, and charging with the USB cable should be done sparingly.
Cool that's good to hear, I just wanted to be a bit on the cautious side.
uansari1: so it's better for the battery to charge it with the power adapter? Offhand do you know what kind of drawbacks would occur if we were to use the usb cable instead? I'll try to do some research on it a bit later, if using the adapter means keeping the battery healthier I'd be all for it.

What we were told, and this was in the G1 forum, was that the battery life and capacity is maximized when using the charger, and over time if you only charge with the USB cable, the capacity can go down...meaning it loses calibration over time.
Don't worry about the battery getting warm... the phone is designed for it, and so is the battery.

T-Mobile HD2 takes too long to recharge the battery

Hello folks, I am very concerned with my HTC HD2 as it takes like over 4 hours to fully recharge the battery. I have got this HD2 from the market here on XDA and it works very good overall, except for this problem when recharging it. I thought it was the charger and I have tried many usb to wall chargers even the the iPhone's 4 one, but nothing has changed.
I have also tried several roms and kernels but nothing has changed on this side as well. I wiped everything and put back win mobile 6.5 T-mobile stock rom, but hey, no difference here too..
I am wondering if there might be something wrong with the phone itself or can it be the battery going in holiday???....
How can I figure this out???
I have downloaded Battery Doctor from the market and it says the battery is in good health, and I get up to 14 hours with a full charge with mytouch 4G rom and kernel rafpigna 1.7 cpu 1.3Ghz OC.
Is anyone else experiencing the same problem ??? do you guys have any suggests ???
This problem is driving me really crazy...

How many hours does your battery last???
Are you using the original HD2 charger? I have tried many different chargers and they always charge at a different rate. It has to be that, not the battery.

Unfortunately it came with its original charger broken and I have never had the pleasure to try with it.. Anyways I am using a charger that has the same specs of the original one, which is the usb charger of the iPhone 4, and yea same result ...
I have downloaded currentwidget from the market and it gets less than 200mA of current in, when it usually should get around 400mA, sometimes the value goes down to 200mA as well, which makes me really wonder the problem might be the usb port of the phone .
Does a broken battery does that as well??

I think it has to do with the charger you're using . When I charge mine I usually see anything from 500+mA to 700+mA on my battery monitor widget depending on how much charge the battery has, and like Segnale007 said it usually takes about 2 hrs to fully charge.

I can't say it's the battery cause you say it lasts you 14 hours, usb port? maybe. Your battery is good for it to last that much (on averge usage of course). It's the different charger that you're using.

That's your issue there, 0.2A (aka 200mA).
The UK HD2 charger for example, is 1A (aka 1000mA).
To work out the maximum time it should take to charge the battery:
(capacity x inefficiency factor) / charging current
(1230 x 1.15)/200 = 7 hours
(1230 x 1.15)/1000 = 1.4 hours

That charger only delievers 0.2 A which is 200ma , you need at least a 500ma charger, mine is a 1 A ( 1000 ma ) and its quite normal to see a 700 ma rate while charging..

Take a look on ebay or any local phone shop/online phone accessory shop.
You want a micro usb charger that has an output current of at least 500mA/0.5A
The original HTC ones are 1000mA.
Blackberry ones I've seen are 700mA so they're good enough.
200mA isn't a problem, it won't damage your battery, in fact it will live slightly longer as it's being put under less stress when charging, but don't use your phone while you're charging with it as you'll be drawing more current than the charger can supply.
So for instance, if you wanted a car charger so you could use the phone as a satnav and talk via bluetooth, you'd need a 1A charger to cope with the drain on the battery.

With very, very light use about 55 hrs. That's not extended.
Alright, my dad has managed to temporary fix its original charger and I can confirm there's nothing wrong with the battery and the phone itself. It gets beyond 800mA with the original charger and fully recharge the batter within an hour and half, which is great..
Ok now I have to find a compatible USB to wall charger with the same frequency.
Since its a T-Mobile US HD2 its original charger is american, and since I am in Italy I'd get an Italian standard wall charger. Does the Italian HD2 original wall charger has the same frequency of the american one??
Thanks

Galaxy S2 + iPhone charger = Nuclear rocket charger

I don't know what drug Apple put in their chargers, but i've always noticed my iPhone charging waaaay faster than my S2.
I even tried draining them both to 0%, and charging them with their original chargers. As soon as the iPhone was full of juice, the S2 was just about 50 or 60%
So i did some research about the safety of using the Apple charger, and it appeared to be all OK.
I'm going to end up buying a new battery anyways because i feel like mine has worn out, so i thought it was a good idea to plug the S2 in the fruitplug.
After i plugged the USB cable into the Apple charger, i immediately noticed the phone charging way faster. Waaay faster.
The phone does get a little warmer, but not too warm. I charged the phone from 8% to 100% in less than a hour!
I'm still experimenting the safety of this, by constantly keeping a look at the temperatures, and how hot the thing feels, and it appears to stay safe.
I recommend to remove your case and battery cover and keep an eye on your phone if you consider trying this, but for now i can say one thing:
If you have an iDevice in your house, charge your phone with the fruitplug
on the other side... what do you think about it? Would you try it?

According to the information on the charger, it outputs 1A. My samsung charger also outputs 1A, yet it charges faster with the iPhone charger.
I did some quick research and found that the iPhone charger would have a special sort of **** inside of it that charges the phone in a different way. Not sure if bull**** or actually true, but they did put some sort of magic or drug in that thing to make it hypercharge anything i charge in it
They couldn't have put anything inside, it all depends of voltage and amperage.
You can use charger with higher amperage than your device need though.
And, yea, you can use charger with more amps, but you cannot use charger with higher voltage than 5V.
iPad charger gives [email protected], but last time I tried it with a Samsung phone, it wouldn't charge.
Nightshadow931 said:

The higher the amperage, the faster your phone will charge.
You can use charger with higher amperage than your device need, your phone would charge just fine, only faster. But it would cause heating your device, thus reducing the life of your battery.

tablet/smartphone 5V | 2A,Micro USB
I buy charger for tablet/smartphone [email protected] It charges 3x faster.
I check all the chargers i have with current widget, a nice little app tell how much mv your battery have left and how much your charger putting in. I plug in a 600mah charger and i get around 500-550mah input. With a 2a charger i get 641mah consistantly, so i guess that's thr limit of our device
So 650mah, and a 1650mah battery, that means 2 and a half hour for full cycle. And that also means something is happening to that apple juicer

This.
S2's hardware doesn't allow it to charge more than 650mAh from an external charger. So it doesn't matter if you're using 1Ah or 2Ah charger, it will be the same.
Now, that's for the international i9100, who knows if there's something different with other versions or if the phone has a faulty hardware. I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.

Now, that's for the international i9100, who knows if there's something different with other versions or if the phone has a faulty hardware. I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.

I got European s2, would that make any difference?
What I know is that the s2 never will charge over 650mA per hour. I use a 700mA charger and incoming at ~640mA on my s2.
Maybe a battery charger will do better than charging through phone?

I check all the chargers i have with current widget, a nice little app tell how much mv your battery have left and how much your charger putting in. I plug in a 600mah charger and i get around 500-550mah input. With a 2a charger i get 641mah consistantly, so i guess that's thr limit of our device
So 650mah, and a 1650mah battery, that means 2 and a half hour for full cycle. And that also means something is happening to that apple juicer

How did u make it work ? For me it shows 0mA always. I tried with v0.38 though, could you send me an apk for the latest version (0.40) from play store, cause it keeps telling me that the app is not compatible with my device.
Also, are u on jb or kk ?

I install it from gg play and it works, no trouble there. Im using cm10.1, and i have tp resize the widget to have full vision of it. Anw, just got a ipad mini charger, 1A, plug in and it show around 640mah. 2.5h for a full cycle, that means op's charger have some problem. Too good to br true

A charging dock for the battery only, maybe. But be careful of those, they can make battery "fat" then eventually broke

I dont have a proper charging dock though, i can only guess when it's finish, and that's dangerous. Im using an ipad mini charger now and it's fine, just can do the 1hour-to-full like op's

Question about not original charger

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.

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.
