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.
I've looked in the manual and searched on Google but no information found about preventing overcharging if you leave your phone charging overnight. My S4's battery was pretty bad near the end of its run so I'm trying to avoid that with the S6.

I would assume so as most modern chargers do, especially the ones that come with the phone.
My question is, does the wireless charging protect against overcharging?
Unless Samsung wants every phone to explode YES THEY DO HAVE OVERCHARGE PROTECTION LOLOLOLOL what a dumb question..
The phone does indeed stop charging once it hits 100% so definitely no overcharging. I use an Anker 40w mutiport USB charger for all my devices and the S6 definitely has no issues as far as overcharging is concerned. Have tested the stock adaptive fast charger too. Same results. Nothing to worry about.

Actually cheetah2k, your answer is pretty dumb. It's a great question. It depends on the charger. For example, some advertise as having overcharge protection while some, such as Samsung's own charging stand, say to remove from charger once charged. Otherwise the battery can overheat and shorten the life of the battery. Read the product description carefully if leaving the phone in the charger for longer periods is anticipated.
My S6 is generally plugged in most of the time when I'm home just like a desktop PC is. I use the original Samsung Fast Charger with an Anker PowerLine MicroUSB cable plus disabled Fast Charging feature on my phone.
I experience no heat issues, no battery degradation and I've been using it this way since July 2015.
The exploding Note 7 though, kind of strange that the S6 is way safer.
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.

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!).
Hi all,
I'm new to Samsung, with S8+ EMEA version (non-Qualcomm CPU) for ~3 months now.
This is after ~10 year with HTC while the last unit (up until 3 months ago) was the M9.
Using the same good quick car charger (compatible QC2.0) and different (original) cable I gets much slower charging with the S8+ vs. the HTC.
The scenario is the same in terms of applications and usage and both units confirm this is a "Quick charge" but the S8+ is raising in ~1% per 10 minutes while HTC did ~1% per 2 minutes.
Both were in the same light conditions, same battery temperature and such so I really wonder what the source is.
The S8+ will be fast charging indeed if stays unused in the same charger...
Thanks,
Oren
Just a guess, I believe it's heat management. Quick Change will slow down if the phone/battery is getting too hot to protect the battery. Mine behaves the same, it does not charge quick at all when I have Waze running.

Battery is in the level of 30c and less.

Got the same problem . In my case was the cable and the charger I use before aukey quick charge 2.0 .it was a faulty cable solved. Go on playstore and search for ampere application check there how much you have and report back here we can compare to see if you got a faulty charger or USB cable

I'm also with Aukey quick charge 2 and the original Samsung USB cable but.
The fact is that it does indicate it's fast charging on the notifications bar.
Also, if it's closed, it does charge fast so cable and charger are fine.
The problem is somehow with the charging control while it's being used with Waze, for example, then the HTC was progressing in the charge while Samsung doesn't much proceed...

I done this yesterday . I bought also the bk disabler package for 1.99£ from app store and I can ensure you that the charging is so fast now
I am not make advertising or sell something I just wanted to help you. Yesterday got 6.30 hours screen on time and the charging time decreased

My conclusion is that probably the large screen with the high brightness in daylight is the reason for the slow charge.
Usually, during night time, the same charger, cable and applications will result in much better charging progress.
Again, temperature is not a factor as I do cool it if needed and check the battery temporary to assure it is cool.

So I try sorted this about 4 months.
Original cable and adapter and another 2 non original and all time same results. Nowhere it's say nothing about charging. Samsung block proper charging when is display on. I was ask them in chat they told me advice " turn off display when is charging" that is great advice when you need Nav and charging phone.
So I went to Samsung repair centre and they check phone and say all is fine so I told them my problem and they say unofficialy Samsung got some security advise when is charging and display isn't off that charging didn't work not like fast either slow charging is just keep alive.
Google new pixel have temperature block and LG have same thing like Samsung.
I know fast charging will problem with that big display and when will on. Ok but why didn't charge like slow charging. I not need phone charge in 1.5 hours but when I charging 5 hours and got +20% that is Bull****. Then come message " charging was stop then will cool down."
That is full of the Internet now. Many people has same problem.
I'm just interest if another companys Nokia one+ or HTC huawei xiaomi etc has same problem

I still believe it's related to the Note 7 issues, they are more aggressive about keeping the phone battery cool when charging. Just speculation on my part but it kinda makes sense.
As I mentioned before, with htc m9 charging was faster, it is also QC2 qualified phone.
And again, my battery temperature is low, it's against the air conditioning specifically for that purpose.

I think that what you will find is that the phone doesn't go above about 1.5A when the screen is on to keep the phone cool and protect against note 7 issues. I find my phone charges fast enough on Waze with a qc2.0 charger
Is there any solution for this issue? Can root app do something about it?
S22 Ultra 45W vs S22 Ultra 25W vs S21 Ultra 25W charging test
wouldve expected it to charge much faster, especially when you consider the smaller battery.
Totally expected, 45W works just at lower temperatures and under 50% charge as it was back in the Note 10+ days. It's useful only when you are topping up on the go, for 0-100% it's almost the same

Why expected? That was for previous models. Battery charging could have been improved on this phone too.

Well it is improved, it was downgraded 2 years ago to be fair and now is back to that state. It charges faster from 0% to 50% which is exactly how it used to work before. If you expected something different your expectations were wrong, don't know what to say. Even devices with very fast charge charge faster for the first half then slow down considerably. Samsung has always had a more conservative approach on charging after the Note 7 debacle, that's why I expected it to be managed like it was before.

I've traded my Oneplus 7 pro. A 3 year old phone and It still charges much faster than S22 Ultra. Considering to I'm paying for a flagship phone which is over £1000 and it's charging technology called "Super fast" charging. Yeah I'm a bit disappointed.

The N10+ with the 25w brick will fast charge from 5-70% at the rate of 2%@min on its 4300mAh battery. Between 70-82% it may ramp down slightly, at 90% fast charging disengages.
This is dependent on battery start charging temperature, if too low or high fast charging will not engage, and battery condition. A 20% charge in 10 minutes isn't bad...
Fast charging is limited by heat buildup in the battery caused by internal resistance. The Li cell charging process is actually an endothermic reaction but is outweighed by the internal resistance generated heat.
I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.
Looks like they're using an older 45 watter. The new ones are the real 45 watts.

I heard that was the case. The old 45W charger throttled, making it act like a 25W charger. The new one has PPS and is PD 3.0?

The old 45 Watt averaged about 28 watts of power iirc. The new one will supposedly give the full advertised wattage. I'm just shocked sammobile out of all sites did not know this...

That is shocking. Do you think the new charger will output less heat to the S22 Ultra because of better efficiency thanks to PPS?

I doubt it. QC boosts the charge wattage by increasing the voltage; more volts less amps means less parasitic waste heat.
What's left to improve on the charging protocol side? They to improve the battery itself now for any meaningful performance improvements.
These manufacturers push the hype, the reviewers do too, then long after the release the truth finally comes out.
If you can wait a few months for the dust to settle you'll get a better idea of what to expect.
There is a new 45w charger, model EP-T4510XBEGGB. This one seems to work fine and not overheat.

Curious as to what your thoughts are regarding the Chargie since Samsung has now added the same charge up to 80% feature in Android 12 under device care. Is it now redundant?

And of course that one is sold out everywhere lol, this happens everytime sammy launches a new device. All the accessories are never available, pretty bad they cant get this right its so annoying for us early adopters.

i have those USB-C cable with watt LED display. it only showing 31w on my home 65w aftermarket charger,
also showing only 31w on my 65w aftermarket car charger.
I'm using my OP9P charger lol it works really fast so...I didn't need to buy a separate charger. Thank God since it's sold out
