Hello Guys!
I got today a new P3110 and I discacharged it to 2% and I plugged it now to load.
I have seen the charger pushes 2A @ 5V , this is pretty much for a battery of 4Ah, I know from my batteries ( AA AAA and others) that the charging current should be max. 1/3 of the capacity of battery.
So my question is: IS it better to charge it with the Samsung Galaxy S2 charger which provides only 0,[email protected],1V ?
It would last app. 6h to charge it till its full ( can be done over night, hopefully the charger wont melt)....
What do you think about that? Woul it harm to battery(li poly) to do it with small current?
cheers
If the charger seems much then tell me why Samsung made it.

to destroy the battery faster, through much more currency than actually needed, so you have to buy a new one....

You have got to be kidding me. ITS SO THE TAB CHARGES FASTER. IT WON'T KILL THE BATTERY!!!!
Its because the tab has a much bigger battery 4000mah vs 16xxmah.
It charges it faster

Of couse it charges faster, but for long therm it will kill the battery faster. Its usual, like every battery. Every fast charger is not good for battery, I just wanted to know if somebody have a expieriance...

Battery life span is a matter of charge cycles 0%-100%-0%. That is 1 cycle and surely batteries don't discharge to 0% not charge fully to 100%
-AFAIK- Even with lithium, Its the heat build up when "fast" charging that shortens any battery life - (same with fast discharging- I would never use those apps that do so) , so I agree with shOne. I have the same model & have noticed the battery does get quite hot when mains charging,( though have never thought to check charging AH).
I would imagine that the only damage you would do with using phone charger would be to the charger, by sucking out more than it can handle, not the battery ! -
-- But why not charge it via a pc usb port - this take a lot longer (so presume much lower AH) than the mains plug in charger - Most usb pc ports are nowadays - permanently live, even when pc off - same with the usb on a modern sky/virgin box. My battery does not get hot, charging this way. I dont know what the charge rate is charging this way ,because both the inbuilt notification & my battery app say "discharging" - (although actually charging)
(I agree that Samsung have provided a quick mains charger, and wouldnt be averse to selling replacement batteries earlier than would otherwise be neccessary, !! (I wouldnt use cheap replacement batteries in any I.T. stuff - I "blew up " a laptop once as a result!!)
I believe that the 2 amp charge is reasonable with the out put of most lithium batteries for this type of device. Since it is a lithium it will not be overcharging or over heating due to sensing, it would be a serious fire hazard... fyi I use a2 amp charger from Wal-Mart and I do not notice my device really heating up...

Agreed. The worst I got was a cheap replacement off a street without a packaging for a dollar. When I plugged it in for a few minutes the battery turned extremely hit and the battery expanded as if it was a puffer fish that took an electric shock

LOL.........mine was a supposed "genuine" DELL replacement battery I got on EB from HK. On the first charge (in the bedroom) heard a strange hissing then a loud "pop". Some of the underside casing was actually melted and there was battery gunge all over the internals!

A lot of things I bought from Hong Kong off Ebay actually came from mainland China pfff.....
It's those low quality defects they send you. Mass market goods in china doesn't require quality passes unlike Hong Kong where it's illegal once they get pass customs.

OK, electronics 101, chargers DO NOT PUSH power to a a battery, 2 AMPS is the chargers MAXIMUM OUTPUT, the device plugged to the charger PULLS what it wants (up to a maximum of 2A of current) so it can charge in a reasonable amount of time, you may be able to charge your tablet with a lower output charger but all it would do is take longer to charge (if the charger even had the power output greater then the static draw of the device), which is why most tablets simply CANNOT be charged by the USB 2.0 port on a computer or other small .5 A output chargers. You may very well charge while generating less heat, because of the slower charge cycle using the .7A S2 charger, but at the same time if you try to use the tablet while it's charging on the smaller charger it may very well drop in battery percentage as the smaller charger may not be enough to maintain the current requirements to charge the battery and run the device.
So in short, would charging with the smaller charger harm the battery, NO, but if it is enough to actually charge the device it will take atleast DOUBLE the amount of time to recharge as it would with the regular 2A charger.
I just got myself a Nokia DT-900 Wireless charger (Got it at a clearance at the Nokia store) for use with my Nexus 5 and my Nexus 7.
I charged the nexus 5 with it now. While it charges perfectly, even with a case on, the back of the phone gets a little warm. Not hot, just warm. I was wondering if this is any cause for concern, or if this is normal. Have not tried with my nexus 7 though.
Does the nexus 5/7 work perfectly with the Nokia wireless charger, or is it Incompatibility that is causing the phone to warm up a little?

As it's an LG, I doubt it's any different from the Nexus one. Both have the same specs. Have emailed Google regarding this, their reply was the standard 'We do not recommend using Non-Nexus chargers for Nexus devices'. I told them all QI chargers were actually supposed to work, and am awaiting their reply. Will follow up on this.

I bought a QI wireless charger when I purchased the phone based on excellent reviews on Amazon. I've since stopped using it just because of random overheating and generally the phone was warmer than when charging via USB. It was a feeling that overtime my phone would suffer.

my thoughts exactly
Wireless charging, by its very nature, generates a small amount of heat. It is perfectly normal for your phone to get a bit warm whenever you're charging via any means, but especially when wireless charging. The key is the phrase "a bit warm." It should never be hot to the touch, just warm. The phone was designed to handle this, and there will be no adverse effects. In fact, the heat generated is much less than is generated by the CPU during heavy use (such as during a graphic intensive game).
I regularly use my phone with the official nexus charger (in my car), the Nokia DT-910 (the stand-up version of the DT-900 -- my main overnight charger), and the Samsung S-Charger Pad (at work). All are perfectly compatible with the N5. In fact, the only name-brand charger I'd steer clear of is the Tylt Vu, because there have been numerous incidents of overheating with that charger (i.e., the phone gets very hot to the touch).

Yep, I read online that the Tylt Vu has some issues.
I spoke to Google about the Nokia charger, and they said the temp of the phone is normal. They did warn me that the Nokia does not cut charging automatically when it gets to 100%, and that I should Take it off manually
Using a case increases the distance between the phone and coil which can cause the phone to heat up even more. Even wired charging heats the battery so some extra warmth from the 25% lost energy seems normal.

Lots of people who use wireless chargers say this but I am still skeptical. I would like to see battery capacity tests from two of the same devices. One that was only charged with wireless charging and the other only charged via USB.
My money says the wireless charged device will have significantly less battery capacity than the usb charged device after 1-2 years of use.

Yes, But seeing as most of us use the phone for only 1-2 years, I personally don't see a difference. Maybe the battery will lose capacity over time, but that's going to happen anyway. This will maybe speed up the process by about 20%.

That may be true, but that argument lies on shaky ground, since there are a lot of other ways you can (theoretically) reduce battery life as well. In theory, not allowing the battery to drain completely during each charge cycle, or not removing the phone from the charger the instant it's fully charged can reduce battery life, yet nobody charges their phone that way. There's also the counter-argument that plugging the charging cable in every single day can prematurely wear out, or break, the (very fragile) USB connector on the phone, which would result in the inability to charge at all. (I went through SOOO many Galaxy Nexuses... Nexes? Nexii? Whatever... because of that issue.)
The point is that sometimes, convenience takes priority over the possibility of slightly reduced battery life, and it's hard to argue against the convenience of wireless charging.
Plus, as Srivas95 stated, most of us will move on to the next device long before any such battery degradation becomes an issue.

What you say is right, my Nexus 5 has been with me for just 4 months and I can already see that the jack is kind of loose. That is one of the reasons I got a wireless charger in the first place.
Gear S2 classic comes with 0.7A charger. Wondering I can use iPhone charger which has output 5V 1A?
I used my Note5 Samsung faster charger without issue.
Throwing juice at the battery faster than it was intended to will shorten its life. Not a big deal for a device with a removable battery but I wouldn't want to do it with my S2. Especially since it already charges in about an hour.
Oops I tend to use my S6 fast charger

No. Your probably right in this case and it wouldn't. I'm guessing that the charging dock would only draw what it needs. Wireless charging might be a different story. I'd have to read up on it. My comment centered mostly around heat and excess heat created during a faster than normal charge and the long term affects.

I think it would make the most sense that wireless charging has at least, all the current regulator circuits wired charging has.
I'm using my old Note 2's charger (2.1A) without any issues. Charging circuit inside watch probably limits it to 0.5A anyway.

I was also wondering about taking the chargerfrommy Note 4 to charge the watch. It would be more comfortable to not always take everything with you and to decimize it to a minimum.
In general you can provide a 5 amps charger for a device that will take 1 amp without a problem because as already explained, the device will draw that amount of current, that it can take. Also with inductive charging there shouldn't be any difference.
You can test how your watch will react to another charger and if you find it getting very hot compared to the genuine charger and find any other incompatibilities, you should stop the charging process but otherwise i can't see any problems.
Hey guys,
I was looking for some clarification on this topic.
So I heard on a youtube video (can't remember which, for the life of me, I just know it was an S8 video) that Wireless Charging has a better impact on battery in the long run.
They had stated that the battery would continue to hold a better charge over time, where as, if you used wired charging, the amount of charge the battery can hold over time would be much less to when you first got it.
Now I do know that battery gets worse over time, however, I have never heard anything about how wireless charging can increase the longitivtiy of the battery.
Maybe someone on here might have more information on this?
I will try to find that youtube video but if this is the case, then I will definitely need to get a wireless charger.
Regards
Unless this youtuber tested 2 phones for a year, charging one with a cable and another with wireless charging i wouldn't listen to what they're saying.

Yeah I agree. A believe a charge cycle is the same regardless of how it is being charged.
Would never think wired charging puts more stress on battery life.
I think though that with wireless charging once the phone is fully charged the pad cuts out so it won't over charge
With a wired connection when the phone is charged its still consistently trying to charge which can end up damage battering the long term

This is also what I have been wondering. If this is true then I may get a nice wireless pad for charging overnight (maybe the new official samsung "convertible" one but its damn expensive). I would have thought that the phone itself knows when a battery is charged and stops drawing the current from the cable though, so it would make no difference either way if that is true (but perhaps its not?).
But I did hear the exact opposite to op, that wireless charging was worse for the batteries, possibly due to the heat generated. But I don't know how true that is.
True
It's better for the battery because it charges it more slowly than a direct wired connection. There is no more heat buildup than using a wired charger, in fact likely less since the charging rate is lower.
As for the other comment that a wired charger doesn't shut off but keeps charging once the battery is full is patently false. The charging circuits whether wired or wireless are quite intelligent and gradually ramp down the charging current as the battery approaches capacity, ultimately delivering just enough current to keep the phone running. In a closed system the energy has to go somewhere and if the charger didn't do this you'd have 18W of power being dissipated as heat and a serious problem on your hands.

For wireless I believe the heat generated is more, it is about the method of delivering the power, not the speed. The induction used to transfer power wirelessly is obviously going to be far less efficient and will generate more heat to get even a slower transfer rate then getting the power straight down a cable (but if someone knows otherwise then feel free to correct me). But then I guess the slower charging rate might also put less stress on the battery which is probably good.
For the wired, what you are basically saying is that leaving a phone plugged in to a wired charger will not harm it since the current will have been reduced in the same way a car battery charger might reduce it to a "maintenance" mode once it is fully charged. So people are believing the old myths that you can overcharge a phone, which would seem to be impossible (although I do wonder why they keep slapping up notifications saying things like "FULLY CHARGED! UNPLUG CABLE!" as if leaving it plugged in would in some way damage it!).
Just saw this which explains the overcharging possibility (or lack of)

The coils themselves don't generate a significant amount of heat, it's the battery itself that causes the phone to get hot. Slower charging means less heat, which is better for your battery so wireless charging will increase your battery life. As the article notes it is also best to keep your phone above 40% charge, partly because fast chargers slow down significantly after 50% to save the battery. That initial burst from 0-50% is done to save you from a dying battery but it takes its toll.
Also note that the S8/S8+ have new battery technology that provides much improved battery life. They're saying 5% loss of capacity after two years compared to 20% for previous generations.
As a bonus not continuously plugging/unplugging a cable from your USB port will make that last longer too. I hardly ever plug my S7 Edge into a physical cable, and I know quite a few people who have killed their USB ports and can no longer charge and or transfer data from them.

Yeah I am torn at the moment between using cable and getting a wireless charger. I like my stuff charged asap but that's partly because i never leave it plugged in overnight and want it charged before bed (which I now know is not a problem anyway) and partly because i want to be able to unplug it to use it if i get a message or email, which isn't an issue with wireless as I can just pick it up and put it back on there after. I assume taking it off the charging pad and putting it back on will not have any detrimental effects to the battery. I am just trying to weigh up the pros and cons of each. All things considered I am leaning towards wireless, particularly if it isn't worse for the battery (although lets face it the difference in degradation between wireless and wired, is going to be so small it's probably not even noticeable after a couple of years by which time I would have a new phone anyway). I wonder if there is a better wireless charger which will be more future proof than the new convertible samsung one (in case I ditch samsung in future) and still give max speed, I would like one that is tilted so I can see the screen though.
My s5 is 3 years old and has only ever been charged by the massive double width "micro USB" cable which takes some force to get in and out of the socket. Still works perfectly though. Never had any usb port of any kind on any device fail, no idea what these other people are doing to kill them!

Having the dock by my bed is very convenient. Just place it on at night and pick it up during the morning. If I need to grab it for anything I can without getting tangled up in wires and it even sits at the right angle so that the always on display becomes my nightstand clock/alarm clock. Once you've gone wireless you won't go back.

I always turn my phone off at night anyway so I don't get disturbed by some spam message or something (I know I can probably set it up to be silent at certain times, but then why leave it on at all, using the battery for nothing). £70 for that Samsung charger though!! I know there are much cheaper ones but I am not sure they will charge at the same rate, the new samsung one charges faster than any previous wireless charger AFAIK and I would want one where the phone can sit up, and most are just flat. Hmmmm although the do have it for £50 on amazon sold by "fonejoy", still steep though.
This one looks good https://www.amazon.co.uk/CHOETECH-W...=UTF8&qid=1492192247&sr=1-9&keywords=choetech but not sure if itll charge at the same speed as the new samsung one and doesnt use a USB-C connector which probably rules it out. May as well just get the samsung one.
I use the US version of this and it works fine. https://www.amazon.co.uk/d/Mobile-P...d=1492192742&sr=1-5&keywords=rav+power+qc+2.0. The Fast Charging Dock comes with a cable so that should be all you need.
And yes, I have my Do Not Disturb settings to suppress notifications 10:30PM to 6:30AM. Wife complained she couldn't sleep with all that noise going on

Thats a wall charger? I'm talking about the charging pad itself. I believe the new Samsung one outputs 15w so is faster than any previous ones which are all 10w I think.

There are only two types of charging dock, standard and fast-charge. None of them output 15W to the phone. The expensive Samsung is just a fancy fast-charge dock so it will charge at the same rate as the Seneo and others that support fast-charge. The Samsung fast-charge adapter only provides a maximum output power of 15W (9V @ 1.67A) so it would require 100% transfer efficiency to charge the phone at that power, and in reality it's only about 65% so at most you'll see 10W versus standard Qi charging at around 7W.
All of the Seneo chargers I have coupled with RavPower or Samsung Fast-Charge adapters charge at the same rate (10W to begin with tapering off to 7W above 50% charge).

Ahh ok, I will have to check out a few seneo pads.
If your using fast charging AKA Adaptive charging it shouldn't matter either way. The Fast charging port on the phone, and the wireless charging should go through the phone and the phone should automatically stop all charging going to the battery. This is the reason why if you were to leave your fast charger on all night whether it be Wireless or wired, you can pick your phone up at 99% or 98% instead of 100%. The phone stopped charging, then when it drops to a certain % it starts to charge up again.
As far as which is actually best for strain, it shouldnt matter because afaik to the battery its the all the same. Wireless charging just has some coils almost that send the charge wirelessly, but it still goes to the same place.
This is what I have read from google, so I am no expert on the subject, but it seemed pretty legit, and makes sense to me, a person with a Tech background. If anyone knows better please be my guest.
I'm going with wireless charging pads at home but a magnetic cable for in the car.
Not found a good car holder that has the wireless pad built in so I will stick with my ibolt for a bit longer

There is no correct answer to this question. Battery life is function of many things -
1. Every battery has specified charge cycle. One full charge from min to max is 1 cycle. Two full charge from mid to max is also 1 cycle. So the more you use your device, charge cycles will come to an end more quickly. For example if you use two similar spec phones; first one you use heavily requiring full cycle charge everyday vs second which you use less and requires full charge every alternate day (or to phrase in other way, first is almost completely discharged by evening, second is half discharged). So the theory goes that second phone battery will last double the time than first.
2. Every battery articles you read, you will find recommendation to charge battery in specified current or usually slow charging. Today's battery technology should be immune to this but I still turn fast charging off. It is likely that not all the batteries are immune.
3. Heat is bad for battery. Some wireless chargers heat up. The TYLT VU that I use get uncomfortably warm when I place phone vertically (possibly coils do not align and multiple of them gets activated). Heat build up is there during fast charging too. If you play CPU intensive games and charge at the same time, phone gets warm. All this heat is working negative to the life span of battery.
4. Lithium ion batteries have less chemical stress when they are not fully charged or fully discharged. If you research you will find articles telling one to keep battery between 40% to 90%. Hence I usually do not charge to 100% and if I do, I watch or play games to bring battery level down. Search for best charge level to store lithium ion batteries, I think it is from 45% to 50%. This I guess keeps batteries at the least chemical stress state. So do your maths if you are type who likes to keep battery at 100% charge at all the times.
As you can see there is no straight answer to this question. Battery life is function of all these factors.
Added: I didn't read full article but you can check this link which speaks about impact of heat and leaving battery to full charge state.

Thanks for everyones input on this!
By the way, not sure if it has been mentioned, but this is a pretty cool read:
http://www.androidpolice.com/2017/0...ill-degrade-less-quickly-than-the-galaxy-s7s/
So looks like the S8 won't deteriorate as much over time!
I got the OEM samsung convertible fast charging pad but it doesn't come with a wall plug as I read somewhere (I guess thats just us in the UK getting screwed over yet again). The manual says "Use only Samsung-approved chargers that support fast charging (9v/1.67A, 9v/2A, 12v/2.1A).". So I need a wall plug that will be able to provide the fastest charging speeds from it (which I am guessing is one that does 12v/2.1A??). I dont think all the standard plugs with 2.4a sockets are going to do it right? The "30w" RAVpower one that craigdamey linked says it can do 12v/2A but only for QC3.0 (which I obviously wont get since its just being plugged straight into the charging pad), otherwise its 5v/2.4a. Not sure what one to get now. Theres an Anker 24w one but that says 2.4a per port (I know little about electrics and how these things work!).
In this video I test out both dash charging on the Oneplus 6, and adaptive faster charging on the Samsung Galaxy Note 8 to see which one is faster.
Both devices have a 3300mah battery.
mod edit - link removed
And i can say without watching and without click-baiting that dash charger is much faster! You can calculate it for yourself too. Samsung adaptive fast charging is based old Qualcomm Quick Charge 2.0 and output power is ~15W. Dash charger is 20W.
But nice video still!
Does it really matter?

Yea everyone will just try to find a way or to prove that the phone they bought is best so they do useless comparison all going to change phone within a year it doeent matter stop speaking for thr company just use the phone no offence for the post
I've not watched the video but something else to consider.
Dash charge does hot heat up the phone whilst charging. As such, it's not only quicker but it also does it in a way that is better for battery longevity.
You can use this charging solution whilst driving in the car with GPS and Bluetooth for example without hearing issues which you really can't do on Samsung adaptive charge or other battery charging technologies.

My phone gets warm/hot aka nothing alarming. But the same way op6 charges with dash is no different than the note 8 I used for 6+ months.
It's quicker but not night and day. It's not 2013 anymore. Fast charger with my mate 8/9 was just as fast and battery lasted just as long with all the bells and whistles.
But I personally don't live in a 3rd world country where chargers/outlets arent available.
I thought it was the company I avoided but the community (mostly op forums) are reaching for anything. Battery life and maybe dev community are the only positives.
Never personally had a issue with any other battery technologies.
