Fast Charging Not Always Fast - Samsung Galaxy S7 Questions and Answers

I just picked up a wireless fast charger for use in my car, and found out (via one of those USB power meters) that the S7 isn't actually fast charging even though it says it is. When the screen is off and the device is fully idle, it will charge at 7-12W (power input to the wireless fast charger) but when the screen is on, it drops down to 3-5W which is not even enough to maintain state of charge if I'm doing something like a phone call or GPS navigation. Any ideas why this is? Seems like it might be thermal related. I've got root and various tweaking apps, is there a way to force it to do full 10W charging whenever possible and throttle CPU instead if needed for thermals?

Found the answer to part of my question here: http://androidforums.com/threads/galaxy-s7-wont-fast-charge-if-the-screen-is-on.1002329/
It's by design that if the temperature is too high or the screen is on fast charging is disabled. Question remains if this can be bypassed by root commands/tweaks or not.

It also depends on charger

As long fast charging is switched ON on your phone and the wireless charger does support fast charging, it will say that its fast charging.
However, if your phone while charging got hot or you are charging in a hot ambient temperature, the phone will charge at normal rates even less as the temps of the phone goes up. Thus the fan in the wireless charger
Btw am referring to the official samsung fast charger stand with a gs7, havent tried other brands.
Hope this helps

[Q] Wireless Charging - Daydream

I have a Qi charging stand, and I set up the S6 daydream (screen saver) with news/weather. This is perfect for work to keep it charged wirelessly and keep up with news.
However with wireless charging, it doesn't seem to trickle charge correctly, so the phone keeps oscillating between 99% and 100% every few minutes. More importantly whenever it starts or stops charging, the phone wakes up to tell me so. Sadly we can't install the Xposed app to disable the wake.
When I use a wired charger though, it doesn't seem to have this cycle. Presumably it gets to 100% and trickle charges, and thus the screen does seem to stay off.
Does anyone have this effect, or know of a workaround? Do others use other wireless chargers that are able to trickle charge?

This is an intentional design decision by Samsung, they did it on the S4 as well.
I agree that it is super annoying, and it means that I can't just charge the phone overnight unless I go wired.

[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!).

Question How do you charge your phone?

How do you charge your phone? What type of charging do you have selected?
-fast charging
-super fast charging.
I use a 25W charger and I have super fast chargers selected. I try to charge the phone in the range from 30% to 85%. I also have the battery protection option selected
I always use wireless charging, and I place it on the charger when I go to bed, and pick it up when I get up, as I have for the previous S20 Ultra, and before that the S10+, and the S5 before that. I have never had a battery problem, don't baby it, use it!

I do the same as you. Have wireless charger on my bedside table and one in my car. That's all I use and don't worry about battery dying on me.
I bought an Anker 45W charger, and I have a question.
On my first days, should I use it or use a normal charger? Use health protection or not?
After those few days, I have a meross Smart Power strip , WIFI, that I can schedule each plug individually, even the USB ports. I usually put 2 hours charging for my actual phone and 1 hour for my Galaxy Watch 4. Is this ok? Can I keep the 2 hours for the s22 ultra or reduce the time, since I'll use a 45w?
Thanks for the advice!
I plug it into a 25 watt charger at night. Unplug it when I wake up. Charge as needed throughout the day.
Currently on my 3 year old Note 9, awaiting delivery of my S22U, as with previous phones, I disable fast charging, if the phone has the feature, as it generally isn't good for battery life expectancy. I always plan to keep my phone longer than the one or two years many people do, so battery health/life is important to me. I have a timer-socket adapter, like this, I use for through-the-night charging, whereby, I set a timer duration, depending on the battery level at bedtime. I'll perhaps set the timer to be on and charging the phone between 4 & 5:30am. Apart from the first few charging cycles of a new phone, I don't like to fully charge/discharge the phone often, only occasionally. I top the charge up during the day, if need be, in the car etc but I never use wireless charging even though my car has the ability to. I'll probably start using the wireless charging with my S22U though, as not using it probably doesn't lengthen the expectancy by much. I appreciate battery charging technology has improved greatly recently, I'm just stuck in my ways I guess.
Everybody is talking about charging the phone between 20% and 80% but what about the result? What would the capacity of the phone be in the end of three years of usage if someone charges his phone in that range? and another thing, when you charge your phone, from 20% to 80%, you charge your phone more often than compared to 0-100%. It's said that If you charge your phone more often it's battery will wear off faster, in the other hand you will charge it less with 0-100 but this time your battery will wear of faster because of the known reasons. I'm a bit confused here. Is there any data compares the result of the both cycles after some time?
Baseus 65W GAN charging brick. Bixby Routines set to disable super fast charging at night and enable Battery Protection. I have another automation that reverses that before my wake up alwarm so it's still full when I wake up but stressed the battery less.

Question S22 Ultra Android Auto Battery Drain

I'm wondering if anyone has run into the S22 Ultra problem where the battery drains faster than it can be charged. I'm using Android Auto on my car's screen, so AA is active while I am driving and navigating. The S22U's screen is off. It doesn't matter if I am using wireless AA with a phone holder with built in 15W wireless charging, or wireless AA and the phone plugged into an AC fast charger, or wired AA with my phone plugged into my car's USB C port, the battery on the phone will actually drain faster than it can be charged. I did not have this problem with my S21U. With that phone, after a 3 or 4 hour drive, the battery would be at 100%. With the S22U, it would never reach 100%, but be at 75% or 80% at my destination. Is Android Auto that much of a battery hog on the S22U?

Using my S22 Ultra U1 with wired AA always charges my phone to 100% long before reaching my destination. Using wireless is another story. Did you make sure your fast charging settings are on?

Yep, fast charging is on. And I'm using an AC charger that says "Super Fast Charging 2.0" when on my house current. Could be limited by the AC power plug in my car, but it should still charge faster than it drains I think.
Make sure the charger is good and it's power source as well. Use the correct Samsung cable, limit length to 3 feet.
If the device is drawing too much current the power controller will ramp down the charge current to protect the battery.
Some apps can run with the display off without skewing the charge curve if they don't draw too much current. High battery temperature can also cause this.
It could be a glitch or error in the firmware if the current draw is actually low. Or maybe it part of Samsung's new thermal paranoia. Sammy's just full of rude surprises lately...

Charging issues can be hard to troubleshoot.
In general these devices shouldn't be charged while in use. The most I'll do is sometimes listening with the Buds+ using Poweramp. The N10+ will tolerate this.
Google Services and such tend to use a fair amount of power as may the modem especially if switching between cell towers.
Once fast charging disengages it likely won't reengage unless the charging power is cycled.
So one high current usage spike is all it takes.

Agreed, I've used 65 watt A/C chargers in the car outlet before and work pretty much the same as in the house. Strange that your phone is behaving this way. I have a 2021 Bronco Sport and the wired (usb-c) is plenty strong enough to charge the phone while on AA. The previous Subaru was questionable at times but usually pulled it off on my S21 Ultra. Any way you can check the charging voltage /amperage while using you phone in the car?

The same it's for me, but I noticed that if I rotate the cable the phone will not drain anymore, I know that's weird, but this is the behaviour...Sometimes it's working, sometimes it's not... It depends also if I'm using Waze+Youtube, or only Waze

I've encountered this too. If I plug in a cable one way, charges slowly. If I flip the cable 180°, it charges normally. This also happened on my Note 10+ 5G, and I've seen it happen on my daughter's S22 and S10. I think it is a cable problem, because with some cables I have this issue, but not with other cables. Not all USB-C cables are created equal. Also not all car USB ports or chargers are created equal.
I normally use wireless charging and connect to my car via BT though. I have an iOttie wireless charger in my car and haven't run into this problem. I have it mounted so that an A/C vent blows on the phone to prevent overheating from sunlight. I use Waze and Samsung Music regularly.
I have purchased 3 Port 65W charger for s22 Ultra & its charge Super Fast but there is didn't mention anything about GaN, If it won't have GaN then does my charger is useless?
I have a 2020 Honda CR-V and plug it in wired to the USB port and it charges fine. Doesn't drain or anything. I also have a Weather tech phone cup holder where the Cup is sitting about 8 inches in front of the charge port. So I got the shortest braided cable I could find for neatness which is 18 inches in length.
This should not happen unless there's a problem on your phone coz my phone always charges faster than drain and stays at 100% with power bank only(no fast charge), using navigation map and spotify.

Not a desirable configuration...
The higher the cell voltage and temperature, the faster an Li degrades.
Li's prefer frequent midrange power cycling as opposed to complete charge cycles or the worst staying at or near a full charge state.
If the display is on it's typical behavior for charging to ramp down even stop in order to protect the battery.

General Wireless charging

Wireless charging is awful on this device. No matter what case (or even no case), my phone must often does not charge wirelessly. I've tried multiple chargers. I get the "connected; not charging" message. Sometimes it works, but seems to need to be in the exact spot. Even then, it often stops charging after a while or drains faster than it charges.
Any insight or solution to this?
This is a stock pixel 7 pro, bootloader still locked. Bought from Google store and activated on T-mobile.
What wireless charging pad are you using?
I was having all the same thoughts as you. Had a couple Samsung "fast" wireless chargers. However, bought a new one Costco that's not Samsung and it works as expected. Never have to realign or wake up to a dead phone anymore.
my rooted p7p with tq1a.230205.002
is charging well with wireless pads and wireless powerbanks.
always heating up p7p tho
I don't know why people like using Samsung but I prefer other brands
the backrooms​
My Pixel 7 Pro works fine using this 30w Wireless Charger from Amazon - Nanami 30W Max Wireless Charger
This is the only thing missing from the OnePlus 11 - but I don't care...

A variety that all worked great with my Samsung s20. Ankers, Samsung, and a few generics that worked better. None work well with the pixel 7 pro
I'm using the Belkin 15w charger and it seems to be working well.
I use the wireless charging dock I bought for my OnePlus9 Pro. Never had an issue with charging

In my case, I figured out my wireless charging is unstable if my phone is in any condition where it might get at all warm. The Pixel 7s are just lousy at staying cool, and once the temperature rises to high 30/low 40C (which doesn't take much at all), wireless charging is severely throttled if not completely stopped. So if it's sunny out, I understand my phone won't charge in my car mount. The sun just makes it too hot, and it won't bother (no matter how cool I keep it in my car, direct sunlight on the phone is too much). If it's sitting on my wireless charger and I decide to try and use my phone while it charges, I understand odds are VERY high it will get too hot and stop charging. And if it stops charging because it has overheated, I know now to give up rather than keep readjusting it on the wireless charger, because even if it's not charging, if it's trying, it's still making the phone hotter, which is making it take even longer to cool down and resume charging. So I just take it off and don't bother putting it back on until it's gotten a chance to settle first.
It's finicky and irritating that their flagship has such lousy thermal control, but knowing that my wireless charging issues are linked to my phone's temperature has helped me understand how to keep my phone charged. Those who only charge wirelessly without ever trying to use the phone and only in particularly cool environments may never observe any wireless charging issues at all.

I noticed this too
I find Power saver with less brightness helps, but if it gets hot it's not charging at all
No problems with 2 different wireless chargers with a transparent case.
I measured the power usage with an external device and its mostly the charger uses 14 watts power between 0 and 80%. (don't forget the energy loss with this technology!)
No real overheating. But placing the device correctly affects the power draw a lot.
I agree. It's terrible, no matter what charging pad i use, it always glitchy.
Not to mention, the reverse charging won't work properly either. Plenty of time i need to recharge my buds while travelling to no avail.
I struggled with wireless chargers for P7P too, I tried at least 4 with varying degrees of success but ultimately I just ended up using some of the store credit I got for buying to the phone to get a Pixel Stand 2 and it works great.
I can happily say : MARCH RELEASE FIXED MY WIRELESS CHARGING ISSUE.
