Car Chargers and Charging Question...

I was curious about car chargers and I heard back in the day that if you use a car charger its actually bad for the battery because the power from the car isn't a constant "flow" is that true? Second question is it bad if you leave your Fuze/Touch Pro plugged charging for over 8 hours a day because im at work Mon-Fri and I just leave it plugged in so I was just curious if it will lessen the life of the battery..? Sorry if its dumb questions just curious

I personally use car charger as my main charger.
i used it also for the Herald and TyTnII... and i didn't feel any battery problem.
however you should pay attention for the charger brand/make.
i advise to have the original HTC one.

during the start of the engine, the voltage level may drop and the charger may stop charging, but during the time you drive, there's no problem.
The generator produces about 100 A, so the 500 mA or 1 A current of your changer do not matter

So what if you charge you phone for long periods of time even though battery is fully charged? Any neg effects?

It's not good for any battery to do that, but usually you go into trickle mode, which protects the battery (I don't know if the charger or the phone controls that). Over-charging batteries is one of the things that kills them. You can tell on your phone when it's in trickle mode, because the LED around the scroll wheel stops blinking (well, I think that's the notification for trickle mode-could be wrong).

The phone. Otherwise you couldn't charge via USB

I think the "don't charge in your car or you'll damage your battery or phone" is mostly an urban legend. Yes if you buy a crappy USB cig adapter that doesn't provide stable 5v then good luck. That said, even cheap adapters should be able to provide a good 5v source. 5v regulators have been around for ages. I bought them by the dozen 20 years ago when I was a teenager starting to play around with electronics. Even back then, they were less than a buck each if bought in bulk. So stable 5v supplies are not hard to come by. Voltage dips during startup isn't much of a problem either since regulators (even modern switching ones) only requires 10-20% headroom to operate which means as long as you are seeing 6-7v at the cig adapter, you're good. Your car wouldn't even start if it dipped that low. More likely an issue is the voltage spike that might occur right after the engine starts and the alternator kicks in. Most decent regulators will handle those as well. Chances are, you'll blow your adapter before anything damaging goes to your phone.
Recharging batteries requires a "fixed" current source. Modern rechargeable batteries (Li-Ion, Ni-Mh, etc) have charging profiles for optimal charges. That just means they need different currents at different stages of their charge cycle. It became clear pretty quickly that it was better to build the charging circuit into each device which did the best job for the battery it was designed for. That's been the case since the early mid 90s I think. What this means is that pretty much all devices built to be rechargeable (whether the battery is replaceable or not) only requires a simple consistent voltage source. This is why we have the "Universal" chargers today and why they are so cheap. I would still not pay $20 for one though. I'll spend 10 to get the generic brand which is just as good without the brandname on the package. The funny thing is, most of these power supplies come from just a handful of overseas manufacturers so you might be getting exactly the same thing. The only one's I'd avoid are those really cheap ones like the like the ones you might see on ebay. Most of them are actually good but some less reputable sellers might have gotten reject stock form somewhere and is selling them. These units are rejected because they didn't meet voltage/current specs and the person that was supposed to throw them out sells a huge box of them to someone for $50 or some such.

Li-On batteries dont really have a problem with charging them from any state to full, no memory really. However if you have a full charge and leave it plugged in you can burn them out in which case they do not retain that charge for very long. It will over periods of time shorten the life of the battery. It usually wont happen on the first go (depending on how long after full you leave it charging.)
Safest way to keep your battery happy is not to let it drain to complete empty and to take it off the charger when its done.

Interesting info guys.. so it looks like on the safe side that im not going to leave it plugged in for long hours..

most modern battery chemistry has a life of around 1000 recharge cycles. It doesn't matter if they are full charges or half charges so even though there isn't a classic memory affect, it does nibble away at the recharge cycles. To put it another way, a given battery loses 1/1000 of it's capacity every time it's charged to full charge. Not really memory but just steady degration. All charging circuits today either stops charging or does trickle charge once full. BTW, trickle is a term that applies mainly to pb and NiCad betteries.. today's batteries actually use a form pulse charging for maintenance. Now this protects the battery from overcharging but if you leave it plugged in, the charging circuit will basically go into this mode of letting the battery drain a bit and then charging it. This will eat away at a batteries life. A real world example... my wife and I had near identical laptops ant one point. She left hers plugged in most of the time whereas I drained my battery each time before recharging. When her battery started lasting only 10mins on a "full" charge, mine was still at about 1.5hrs. It took her battery only a year to fail where mine didn't go dead (i.e. below 1hr per charge) until over 18months.
My advice is don't leave it plugged in but once it's about 20-30% of full it's ok to recharge. Hell, if you think about, 1000 recharges will last almost 3 years of daily charging. So what if it only lasted 2. Any of us would likely be on to the next phone or be willing to buy a second battery.

When I exchanged my Fuze for a new one at AT&T, the service person said my battery was bad, due to overcharging.(Battery had a slight bulge). She said leaving my Fuze plugged into my car charger and my computer(with charging turned on) degraded the battery. Phone was about 7 months old.
There is an option to NOT charge the battery when connected by USB to the computer.(kind of indicates no automatic charging control)
Well, I use my Fuze as a computer 12-14 hours a day. I want to see the screen, which means I need it plugged in either to the computer or car charger.
If I turn off recharging when connected to my computer, I end up with a dead battery pretty quickly, since I use it a lot as my business phone with a Bluetooth speakerphone.
The AT&T person said this information was given to them by HTC.

bigger capacity battery or get another device(netbook) that can sustain the 'abuse'?

bigger capacity battery won't solve it
Without it being plugged in, the screen turns off. Even a large battery wouldn't last with the screen on all the time, if even you could figure out how to make it stay on.
I had to plug in the earphone dongle and plug the car charger in to that, to get the screen to stay on in my car. Plugging the car charger directly into the phone, the screen would turn off no matter what I tried.
I guess I need to replace the battery every 8-12 months.

Yikes, there's so much misinformation about batteries in this thread, it's frightening.

so point us to better info
All I know was that my battery was bulging a bit after 7 months of use, and it was holding a charge less and less.
And I reported what AT&T told me..

I'm not saying your battery isn't broken, and I'm not saying your charger (part of the phone nowdays) didn't go haywire and break it. I AM saying, however, that leaving the phone plugged in didn't do it (unless, of course, your charging hardware was faulty, in which case you're screwed anyway).
Lithium-Ion batteries don't get overcharged, because they tend to explode. That's generally considered a no-no for batteries, especially in consumer devices, so the charging hardware is designed to stop charging when the battery is full. An occasional "topping charge" is applied (by some chargers) because of the self-discharge of the cells. I kinda doubt that our phones do that, though, because it's only something like 1h of topping charge once every 20 days.
Let me repeat this again for absolute clarity: lithium-ion chargers STOP CHARGING when the battery is full. Leave it plugged in as long as you want, and (assuming the charging hardware isn't broken) it'll be fine.

So you're saying what AT&T told me was bullsh**t
Not that I believe what AT&T says or the given reasons, which didn't make sense from a technical standpoint.
But then you wonder why there is an option in the Fuze to NOT CHARGE the phone when connected to a computer using USB.
And I did see the bulge, and AT&T did replace the battery under warranty.

But then you wonder why there is an option in the Fuze to NOT CHARGE the phone when connected to a computer using USB.

Perhaps that option is available so when your laptop is not plugged into AC power, you can connect your phone without worrying about draining the laptop battery.

laptop
Seriously doubt that option was designed for laptops.
The phone would take very little from a laptop battery.
And would probably be labeled for laptop use.
I think that the phone drops a few % in power, then recharges, and does that constantly while plugged into a computer, causing the battery to waste the 800-1000 recharge cycles that it has.
Be nice if you could set the phone to not recharge when connected to a computer unless the power dropped 25% --or make it configurable.
Manually turning the charging off/on is impracticable.
Maybe a program can/has been written to cycle the charging off/on properly.

[BATTERY] Cradle Chargers // Voltages, mAh

I'm interested in buying an external battery charger, or a cradle charger, so I can have two batteries going—one always charging outside of the phone—and thus never having to plug my phone in to charge. After a brief eBay search, all of the cheapest ones appear to be the same: you can find the model I'm referring to here.
My concern, however, is with the specifications listed, which read:
Input: AC 100-240V~50/60Hz 0.15A
Output: DC 4.2V~350mA~±50mA
USB: 5.2Vd.c.800mA
The output appears to be 300-400mA, which is slightly lower than a stock charger. As far as I know, this tells me how fast it will charge the battery. Since it will be plugged into the battery charger when I swap batteries (for the full discharge of the other battery), I don't care if it charges slower. However, the voltage appears to be quite low at 4.2V—and I'm entirely unsure how this will affect things. Will it still charge? Can it do damage to the battery? Should I not purchase this unit? What exactly does a lower/higher voltage mean?

Anyone?
Does it work? Is it safe? Does the lower voltage matter?

I've been using this same battery charger for over a year now. It charges my stock and extended battery (3500mAh) without any problem. Yes it does take longer compared to the normal charger to charge your battery because of the low mA but I don't think it has had any affect on my batteries. So the only downside is it takes comparatively longer to charge.

Full power charging dock?

I want a charging dock for my S4 that will feed the phone the full amount of power that it can take, for quickest charging. I believe the stock charger that came with it supplies 2 amps.
I also would like said charger to have a slot for charging a spare battery at the same time.
All the charging docks I've found so far only claim to supply 1 amp to the phone, or less. Except one dock I found that did say it outputs 1.6 amps.
Does anybody know of a charging dock that will supply the full 2 amps? How about one that also has a slot for charging a spare battery?
Thanks.

Would you like it to serve you eggs and ham as well?
Damn.. you are really asking for so much and not nearly searching for it yourself enough if that makes sense.
There are charging docks that have a battery charger slot as well. They have a microusb port for power input. You can use a 2A charger with it and I believe it should be charging the phone at 2A but only when you're not charging the spare battery. I do not have the link as I saw it while randomly browsing through S4 docks on eBay. It's easy enough to find.

No, thanks. If it could cook my eggs and ham, it would be too bulky. LOL!
I looked through roughly 150 listing on eBay. I saw a whole bunch that said 1A output. And a few that were 700 mA, and at least one that was 500 mA. And exactly one model, available from a few different vendors, that said 1.6A output.
I did not see any that said 2A output. Just because the wall wart can supply as much as 2 amps, doesn't mean the charger will actually output that much to the phone.

My advice, is you should risk it.
If you're looking a product with such precise specs, I'm afraid you're not going to find it.

I messaged several different ebay sellers last night to ask if their charger is really only 1A and if they'll be having a 2A model. So far, I've gotten responses from 3 or 4. All of them have said sorry, we only have 1A. Please note, it will charge more slowly.

Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.
So, my quest is now much easier. Apparently, the docks I looked at on eBay that say 1A charging output must say so because the supplied wall adapter only provides 1A. And ones that say that but don't include the AC adapter are just making an assumption about that AC adapter you'll use.
BUT, though the phone charging port may be a passthrough, the slot for charging a second battery (on docks that offer that) would have the charging logic/circuitry built into the dock, so that could still be limited to 1A or less. At least, that's what I think. Could be wrong.
Regardless, i ordered a cheap dual charging dock off eBay that should be here by Friday. Using Galaxy Charging Current (a free app in the Play store), my phone shows 1900 mA charging current when plugged into the OEM charger directly. After I get the dock I ordered, I'll test that and report back.
If the dock will charge the phone at full speed, I can live with the spare battery being charged more slowly.

It's NOT a dock but a charger and it does come with an OEM spare battery. It charges a battery from 0 to 100% in about 4 hours, which is faster than your phone would deplete a battery, even when gaming. Paid $47, no shipping from Amazon
I see the price have changed a bit meanwhile but it's worth it if they still don't charge any shipping. Ships directly from Korea (made in Korea - both, charger and battery)

Hope it works out. The dock i ordered from seidio for my evo 3d did not charge at full power with the supplied adapter. I used a diff cable and power source and the results were better, but still not very good. Most nights I simply removed the cable and plugged the phone directly to it bypassing the dock, kind of defeated the purpose. I hope to find one that keeps the S4 charged.

Well, I received my eBay dock today, 2 days early. It is this one:
http://www.ebay.com/itm/111066155507?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
And when I plug it in and put the phone in it, I get a message that the connected charger is not compatible with this phone. And the phone shows a red X over the battery icon in the notification bar, and doesn't charge at all.
I tried it using the OEM charger and cable, the cable that came with the dock, and I also tried both cables using my OEM charger that came with my Note 10.1 tablet.
Exactly one time, when I put the phone into the dock, it didn't display a message and Galaxy Charging Current (app in Play) showed that it was charging at 1900 mA. But, several times before, and every time after that, it just displayed the message and wouldn't charge at all.

I've seen that and that's a big "no way". My normal deal is, if I run out of battery, it's because I'm out and about. Traveling on a plane. Riding my motorcycle. Whatever. Situations where I don't have the option to plug in. So, I swap batteries on the go and the charge when I get to where I'm going.
This charger on Amazon would require me to carry it, plus my phone charger, plus an additional phone charger to run the separate battery charger. If I were just going to share my phone charger between the phone and the separate charger, I would rather just have the phone on the charger and, when it's fully charged, swap batteries, to charge the next one - not swap the charger cable over to the separate battery charger.
if I were going to go the route of a separate battery charger, I would spend $7 or so on eBay on one of the ones that has a flip-out plug built in and plugs right into the wall. That is the kind I have been using for a while to charge my Rezound batteries when traveling.
The biggest problem with those is that they charge the battery at something like 350mA. Ridiculously slow!

...buddy, that's EXACTLY what this is. It simply gives you the option of charging another OEM battery (in the charger NOT in the phone) BEFORE you go out and about and then swap them as you need.
NO, it's NOT charging as slow as you suggest. They use a technology called direct charge which means that it draws as much (or as little) as your wall plug allows it. In other words if you plug it in the PC USB, then yes, you'll have to wait until you grow a nice thick beard, but if you plug it in your original 2A charger, it'll charge the battery from 0-100% in about 4 hours or less.

Absolutely NOT true:
1. You ONLY need to carry the charger if you plan on recharging the depleted battery BEFORE doing another swap - that's at least 12-15 hours on EXTENSIVELY using BOTH batteries - that's 12-15 hours screen on!!!
2. ONE phone charger can be used on either/or - you'll never have to charge them both in the same time (that's the idea with swapping the batteries, right?)

Up to you buddy, but usually you get what you pay for. The one I suggested comes with an OEM battery. I always suggest using this method over any battery pack as an OEM battery will ALWAYS give you just as much "juice" (this translates into running time) as the...yeah, you guessed it, the Original Equipment Manufacturer's battery. Although the battery packs manufacturers, they all claim huge capacities and running times, this mostly never holds true to the advertised specifications. It's called marketing

I don't think you're getting me. The point is, I get to the end of the day and I need to charge my phone AND the battery I used up. In order to charge both at the same time, using this Samsung separate battery case/charger, I would have to have 2 actual chargers. One to attach to my phone, to charge that battery, and one to attach to the separate case/charger.
Get it now?
More detailed:
- I start the day with 2 fully charged batteries. One is in the phone.
- I ride my motorcycle all day, streaming music via Bluetooth to my helmet, and talking on the phone while I'm riding.
- Before I'm done riding for the day, my battery dies, so I swap it.
- I continue riding, etc.
- I get where I'm going and I'm ready to go to bed.
- I now have a dead battery in one hand and phone with a partly depleted battery in the other hand. I want them to both charge while I'm sleeping.
This separate case/charger does not help me.

No offense, but I believe you don't get it. You say: "I need to charge my phone AND the battery". I should ask you then, do you still need to charge your phone and the BATTERIES (this is the plural, meaning two or more) should you go by my suggestion?
Either, or, if you're such a heavy user and you find yourself at the end of the day with 2 or more depleted batteries on a regular basis, then this becomes even more handy - admittedly, yes, using a second wall plug...or, again, if you're such a heavy user, then buy a 3rd OEM battery - case solved. (1 charger, 2 extra batteries, 1 USB cable, 1 wall plug)

You obviously didn't read my whole last post. Otherwise, you would understand that saying "I need to charge my phone AND the battery" is a short way of saying "I need to charge the battery that's in my phone (but not totally dead yet) AND the battery that I depleted earlier in the day."
And if I added a 3rd OEM battery (which you would also see that there is no need for, if you read my whole previous post), it still would not change the fact that, at the end of the day, I have 2 batteries I need to charge and only 1 wall charger to use. So, the separate case/charger still does not help.
If I charge the battery in my phone and then want to use my one and only wall charger to charge the battery that's in the case/charger, I may as well just swap the batteries and charge the second battery in my phone. Thus, I would save running down the battery that's in my phone while the other battery is charging in the case/charger AND I would save spending $50 on the case/charger when I just used my coupon last night and got an OEM battery straight from Samsung for only $20.

OK, now I did get what you were saying (admittedly, I didn't read the whole post initially) but I still believe that carrying a second set (wall charger + USB cable) would render a better overall usage time without compromising on convenience or quality (again, due to using a certified OEM battery). Think about it, the only "compromise" you're making is carrying another set - which is nothing, both in terms of money and used space/volume.
So, your on-the-go package would consist of: 1 Samsung charger, 1 extra battery and 2 sets of wall chargers/USB cables.

Now, we're getting somewhere!
Your alternative would cost me something like $70 for the case/charger (w/battery) plus a second AC adapter.
My alternative will cost me less than $30. $20 that I already spent on a second OEM battery, plus less than $10 for a wall charger like this:
http://www.ebay.com/itm/Charging-Cr...l_Phone_PDA_Chargers&var=&hash=item27d35082af
And I have less "pieces" to carry around.
Of course, the cheap wall charger won't charge the battery as quickly. But, I have been using a charger just like that for my Rezound batteries for a while now and it always seems to manage to get the job done overnight.
However, the PREFERRED solution is what I asked about in my OP in this thread. I want a dock that will supply full power to the phone and a spare battery at the same time. As I posted later in this thread, it now seems that most any charging dock should supply full power to the phone (as long as the AC adapter is providing 2A). Those docks still won't probably give full power to charge the spare battery, but I can live with that. So, with a dock like that, I would carry the same number of "pieces", but I'd have the advantage of having a dock to prop my phone up next to the bed, so I can see it.

Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.

I can 100% attest to this NOT being true. I have my OEM Samsung S4 2A charger hooked up to my Seidio Innodock Jr. at it receives a MAX of 1020mA. Yes, I realize it isn't the exact charger you are looking for since it doesn't have the spare battery compartment, but Seidio is NOT being truthful to you when they say that it is "a passthrough" dock. Just a heads up!

What are you using to determine your max of 1020A? Galaxy Charging Current? Battery Monitor Widget?

I have both and they do not display the same data. As far as I can tell, GCC shows the actual full incoming current. OTOH, BMW shows the current being used to charge the battery.
When I plug in my OEM charger, GCC shows 1900. But, if the screen is using 100 and other stuff running is using another 100, the BMW would only show 1700.
So, as far as your post about the Innodock, if GCC shows 1020, then that's what I would believe. But, if it's BMW that's telling you 1020, then that could simply be because there is other stuff using almost 900 mA of current.
For the record, I looked through my BMW Usage log from last night when my phone was on the charger. The log shows every 5 minutes, I think. It only had one log entry where it showed 1992. All the rest were in the 1500 - 1600 range or less. And the phone screen was off that whole time.

[q] Wireless Charging Vs Wired Charging - Impact on Battery

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.

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!).

S7e 'original' vs s6 'boosted' batteries.

I'm looking to replace the old battery of my s6 that drains (and heats up?) quickly.
A supposedly original Samsung s7e battery is sold at many websites for ~$20 such as walmart. Even if it is indeed an original (quality) Samsung battery it's still 4~5 years old? On top of that I don't have a case so I'm not too keen on the battery being 1mm thicker.
https://www.walmart.ca/en/ip/Samsung-Galaxy-S7-Edge-G935W8-Battery-Replacement/PRD441YFPLP0QVC
Meanwhile on Amazon a 3800 mah li-polymer battery is sold by 'SHENMZ' with a number of reviews suggesting it has better capacity (at least 3000 mah according to accubattery) than the original S6 battery: https://www.amazon.ca/Upgraded-Rechargeable-Portable-Charging-Protective/dp/B07RN3LDVV/
This 'SPWOMYGD' one is significantly cheaper but the reviews don't look promissing: https://www.amazon.ca/SPWOMYGD-Galaxy-S6-Replacement-EB-BG920ABE/dp/B088M8FZYR/
I'm pretty undecided at this point .

I haven't used the phone for the past 2 weeks or so due to the poor battery battery life, so I guess I'll plug it for 72 hours non-stop or a week or whatever and see, but I'd be really surprised if it will be as good as new .

Yeah, just dont turn it on for 24 hours, try powering on anytime after that, the good thing is if it's that flat, you dont need the capacitor, you just need to slow flash lol, but remember when your (new style) battery is run down to say 10%, it's be best to drain it completely before next charge
