Hi!
I had a battery probelm (same one everyone else seemed to get with there 1yr old uni) where it cuts out at 60% due to the voltage from the battery dropping below the threshold really fast.
Anyway I got a new battery .. my old one was 1650ma (or something like that) I got this new one which is 1750ma (or something like that).. definitely different.
Now I plug my original charger (5v 1a) into the pda and the charge light turns on .. I leave it for an hour and the battery hasn't charged any.. in fact its lost charge as you'd expect if it had been left switched on with no supply.
So.. I plug my motorola krzr charger (5v 550ma) into it and go for a shower/sh*t/shave come back and the battery has gained 10%.. great! atleast I can charge it now.
I also have a desktop cradle charger (5v 1a), same problem.. it sits there forever and a day and discharges... no charge.. (I only got it when I got my new battery so could not prove it before hand)
USB charging works with no problems (not from the cradle one though). So my question is ... Why?
Could it be something to do with my new battery?? I got it from PDAAddons and they've always been good in the past so I believe I can rule out it being a fake.
My new battery is a Li-on Poly.. I've got to admit I didn't look at my old one to see if that was a poly too ... was definitely a li-on though.
I can live with using my moto charger on my exec but unfortunately the ac adapter for my cradle is of a different connector type (female pin sleeve thingy like nokia) so before I search the world for a 5v 550ma version I could do with knowing if i'm barking up the wrong tree and about to waste my money..
Any electronics whizzes in the house say ho!
anyone? :''-(
Aahaahaa!
I'm here! Now, what you say sounds very interesting and yet very strange, why?
- Normally more current from the charger should be better, you cannot put in the PDA more current than it's factory maximum (which I don't know how much it is, but that's not a problem), the internal charger (inside the PDA) knows how much it is and how to limit, also takes care of the right charging profile for your battery.
- You don't have to worry about the exact battery type you bought, boths are Lithium, so chargind profiles are mostly the same, these (LiIon and LiPoly) are "exchangeable" usually (I've heard of no problems until now, since several years I mean).
- If your battery is discharging means only one thing, you're not puttin current into the battery, you're taking it out of it! So, either you might have a deffective charger, a deffective charging circuit (the one inside the PDA) or a defective battery.
- You can charge the battery with your Moto's charger, so battery is probably ok, you have used your original charger/craddle until now, so they might be ok, you have charged one battery at least to 10% so PDA should be ok.
What can it be?
Possibilities are:
Slightly deffective PDA's internal charging circuit, the fact that you can charge with a lower rating charger (the one for your Razr, thing that I've done myself two weeks ago), might point to this, because you have already "limited" the maximum current to 550mA (Razr's charger max current).
Slightly different battery, most of the batteries do have some kind of thermal protection circuit inside (chip + temp sensor, etc.), if the behavior of this circuit is not "compatible" somethin strange can happen, however I personally consider this option not to be the best.
One or two of your chargers might also be somehow "deffective", why? Your original battery might be ok and you are just having problems with your chargers or your High capacity chargers (the original one and that from the craddle) have some problem to give enough juice to your batteries.
I surely might proceed as follows:
try to charge both batteries with a stand alone charger, this is not an easy task, because Lithium batteries are the most "delicate" types, charging method is the "strangest" one, I have two stand alone battery chargers that came as gift with some Nokia batteries I bought from an Ebay seller, eventually, I could give you the full schematic so you can construct it (if you want and if you can).
In this way I will not have any more suspects from the batteries.
Second, test each of my chargers, it can be done by connecting a medium -and suitable- load to each charger for some minutes.
A wire wound ceramic resistor should do the trick, ie for the Razr charger (5V, 550mA) I could use a 250mA load, R=V/I, so 5V/.25A equals 20 ohm (1.25W max power, use at least a 2W resistor, 3 or 5W better).
If the internal PDA circuit should be defective, take it to fix or try to fix for yourself.
Hope this helps

Are you absotively, posilutely certain the AMBER charge light comes on fully?
I leave it for an hour and the battery hasn't charged any.. in fact its lost charge as you'd expect if it had been left switched on with no supply.

There is some anomaly about charging with a plug-in charger. You may have to turn the device on so that it can recognize the charger, then close it and let it turn itself off; or perhaps it's turn it off then on, I'm not sure, but I've encountered similar oddities with both 110v, 220v, and 12v chargers, and I've seen discussion about this anomaly on this and/or other fora. Once you get the AMBER light, you're fine (as long as it's putting out at least +5v; +5.5 is better).
I think it has something to do with its looking for a [non-existent] USB signal along with the voltage under some conditions, but not others, but that's just a wild guess. Anyway, I don't think there's necessarily anything wrong with your battery, device, or charger. Hope this helps. Cheers,
Thanks for the reply, I'm 100% that the amber light turns on. Not only that the screen brightens so it definitely knows its connected. I've tried several combinations of turning it off/on etc during the charge/before but nothing seems to make this desktop charger actually put anything in the battery.
Hi you guys, I lost my original charger on a coffee shop and I ordered one on ebay, It came today but Im afraid it is not the same model than the original one (I have the wrap of the original one on my box). Since I cant compare this one with the original one, would you please confirm that this one will work all right on my phone with the following specs:
Input: 100-240v 50/60hz 0.2A
Output: 5.1V, 0.7A
Thank you in advance for your help.

I would be more concerned with whether or not it would transfer files. The only one I have that works is the original.
I use LG chargers I have in the office and at home and they work flawlessly. Same specs as the one you have.
I'm using an old Nokia n86 usb cable and it connects just fine.
OP, charger doesn't make that much of a difference. The phone will only "accept" the current it needs, not more.
Thank you guys, I was worried about damaging its battery and since it is noy removable... I read somewhere that "underated" chargers damage batteries because they not "feed" as much energy as the battery needs.

The general rule of thumb is that a battery will last longer when it's charged slowly.This generates less heat puts less stress on the battery. Batteries are unique in the sense that they can slowly discharge energy, whereas capacitors can rapidly charge and discharge. With that said, I believe you run a greater risk of damaging your battery with a high amperage "rapid charger" vs. a lower amperage charger. It may take longer to charge, but your battery will thank you. I don't believe you run a risk using the lower amperage charger, but you may outpace your usage vs. the charge that is made on your phone.
I received a replacement AT&T Galaxy S4 earlier this week and it came with another power adapter and all accessories.
The power adapter that came with my first phone was made in China, and it doesn't get very warm when charging. It also seems to charge the battery kind of slow.
The power adapter that came with my replacement was made in Vietnam, and it gets pretty warm when charging. It also seems to charge the battery faster.
I checked the specs on both chargers and they're the same. Am I imagining things, or does the new one from Vietnam really charge faster and get warmer because of it?

In theory its possible, but unlikely. If your in the U.S. the max voltage your gonna be pulling is 110 volts (usually a tiny bit less)
More volts = more heat = faster charging time, but it would also be rougher on the battery. You could always bust out a multi-meter and take some readings
Is it white and says Samsung? The stock S4 charger is 1amp. It will charge super fast with the Note IIs 2amp charger.

The chargers were identical on the outside, except for what country they were made in. They are white S4 chargers.

You're thinking about amperage, not voltage. And the AC voltage won't have any effect on the phone anyway, because the charger converts that to 5V DC.
Hi
I got the Samsung S-Pad charger which the shop states it's for S6 and Samsung states it's for S5, but it's charging my S7 just fine. Using the original charger for my S7 for it. Could it damage the battery or are most of the wireless chargers identical?
Thanks in advance
You can't damage the battery. It's a myth. Use any qi charger you want. As long as your phone charges then you're good.
Sent from my Star-Tac
You can use any qi charger you like, it will not hurt your phone.
I'm using my Samsung charger I bought with my S6... It works fine... But takes almost 3 hours from a low battery... Really want the new Samsung fast charge wireless charger
Hi guys, greetings!

Apparently, I had issue with fast charging problem. Basically what I did was changing cable and charger over and over again. I had to change my cable to which can hold up to 2.1A and a charger that has same output with stock charger which is 5V at 2A and 9V at 1.67A. I even bought enough cables just to see whether it is working or not, yet it doesn't fix my problem. I haven't changed my battery since this issue, I assume that this issue don't came in the battery rather it is from cable or charger. So I changed my flexy charge, but still can't do such a thing.
I had to reset my phone and factory settings, and yet it doesn't fix my problem
For some reason I'm frustrated with normal charge because I had to wait my phone fully charge like around 6 hours. And it drain also around 6 hours on use continuosly.
But it's crazy that this phone can hold it reliable for 6 years without any issue. It still in better shape. My only issue that came up was camera focus, can't read my sim card, and fast charging issue. And a missing S Pen lol. The camera focus and sim card aren't a big issue, since I can use alternative phone. And I can wait longer for my camera to focus to one object.
My questions are :
1) Does the battery affect fast charging too? I have my stock battery here which is 3220 mAh. If it's true, then maybe I'm going to change my battery with a newer one.
2) Is it possible that the processor in it some tiny part (which it controls the fast charging) is broken and that's why fast charging is stopped working?
3) I need to upgrade my phone to a same note series, but it's hard to pick. I kinda like galaxy note 9 than a newer one. But I want you guys to give me opinion. I need a longer battery life and it said note 9 is a beast battery. And a compatible software updates in future.
4) Does the battery that comes up with custom battery capacity is safe? Like does it fast charging? (like a ZeroLemon 11000 mAh and some chinese product that doubles the capacity stock battery)
5) Does the OS affects too? (This is the reason I did factory settings so I can see if it's work or not)
Thank you guys!

Check your microUSB port and make sure the little flap in the port isn't bent and if it's dirty carefully clean the port. If you still have the original battery that came with your phone it will definitely need replaced with a new one. Lithium-ion battery degrade over time and have limited life span.

Yes! I did that before I changed my flexy charger. It didn't fix my problem. It seems like there's some tiny part in processor is broken for some reason (like I told in this thread) or maybe some part an IC in the motherboard who controls it also damaged. I really don't understand how fast charging works.
I came up with a solution that I bought two new stock batteries and a desktop charger. So if my phone's battery is run out, I could change with my alternative battery. But I'm still frustrated for how it can't fast charging again.
1- Try cleaning the charging port with izoprophilic alcohol and some small brush (let dray the port 1-2 hours after, DON'T START the phone)
2- Make sure you have a quality charging cable (the 5$ from gas station or chinese cheap crap there are no good)
3-Same thing like at point 2 but with charger
I have like 3-4 charging flex with ports for note 4 and all are faulty so maybe this if you buy from china or ebay and its not from broken phones original.
If you have all good quality charger and cable and good charging port maybe IC power managament on motherboard is faulty, not CPU.
You can fix it but depends where you live will be more expensive than buying a second hand motherboard from aliexpress, its like 30$ I buy recently for a N910C
Me I don't use fast charging becouse its get too hot and is a secondary device
I want to buy and me a bigger battery I found on batteryUpgrade a 6900mAh but I don't know the quality and its almost 50$

Yes, I also did that way before I change my flexy charger. I brushed it with izoprophilic alcohol on charging port.
I'm pretty sure all I have is a high quality charger and cable. I still have my stock charger. I think there's no issue with charger, I couldn't really tell, since I tried all possible different charger. But with the cable, yes, I tested it one by one, because the issue might come from cable.
I think after all I did what's possible, there's something wrong with my IC charging or processor. I couldn't understand it but, does it guarantee if I changed like I pull the broken IC and put it back a new one, will do the fast charging?
But really though, how does fast charging works? Is it include in processor by some tiny part transistor? or is it an independent IC in the motherboard?
100% is another chip on motherboard that do the charging
I have a similar problem with a samsung tab s t800 that charging very slow becouse of faulty IC power manageament
I'm opened my note 4 for many times until now and repairing it
I've been watching many board repairs I have some skills but no tools to repairs bords for now
Its not the CPU
I watch a similar board fix on note 9 and was a diferent chip on board that manage the charging
Go to a service if you want to repair, don't try to do something at home becouse you have hight chances to destroy much more the phone
Repairing you phone at a repair shop will be more than 30$ so better buy a "new" motherboard from aliexpress
