[Q] Charge Time

I am a bit surprised at how long my shield tablet takes to charge, around 6-8 hours depending on how much battery is left (usually around 20% before I charge).
Is this normal? Or are my expectations a little too high in thinking it would take 2-3 hours to charge?
Many thanks for for answers!!

What charger are you using? Mine doesn't take that long and I'm using NVIIDIA's retail charger (2.1A).

I am using the wall charger that is supplied with the tablet!!
I have spoken with nvidia support about this issue, however they couldn't confirm the charge time for some reason, hence why I am asking here for peoples experience with charging times. Also I have tried googling the answer and haven't found anything!!
Slightly frustrating!!

43 views so far and no answer?
come on people, all I am asking is your charge times for your shield tablets!
pretty please with cream and a cherry on top?

I havn't any exact number for how long the charging take, but I think the charging time has increased with Lollipop. Most of the time it is fully charged over night (6-8 hours) but sometimes it has just charged a few percent.

I have seen some unfortunate charging times as well, but I haven't recorded them or taken note of exactly how long they take. I also have chargers up to 2.1A and thicker gold plated cables I've tried.
Are there any apps I can use to record battery percentage by the minute?

What are we talking about? Time to go to 100% battery or time to go to green led?
There is a 30-45 min time difference between 100% and green led.

When my shield reaches around 20% i'll charge it over night whilst I'm asleep, 6-7 hours later when i wake up i still see the orange led and am surprised at how slow it takes to get to 100%. This is how I noticed the slow recharge time.
Admittedly this is my first tablet, and as stated I'm just surprised and lead me to think maybe the charger that was provided is a dud and/or the tablet is a dud. And no one likes a dud!!
However I just wanted to hear other peoples experiences as maybe the charge time is this long and I've just got too high of an expectation that a device like this should have a charge time of 2-3 hours.
Many thanks for all the responses so far, most appreciated. Keep 'em coming!! :good:

If you want 2 - 3 hours of charging time starting from 15% or 20, you have to get another charger. The stock one is weak. I got a Samsung Note 3 one and after 2 hours and a half, or even less depending the percentage, it's fully charged.

^^^This.
Also, I have a Quick Charge 2.0 charger that I found on Amazon that shows whether or not a device is capable of using the Quick Charge 2.0 standard. My nVidia Shield does, in fact, seem to support it, and charges pretty quickly on this charger. I can't say I've ever had the tablet get below 50% or so, but I've never seen it take more than an hour or two to get the Shield's charge indicator to go green with that charger.

18W. However, in the normal 5V mode, it's only 10W, like any other 2A charger.
In QuickCharge 2.0, the device being charged decides if/when the charger uses the 5V, 9V, and/or 12V charging modes. If the device is not QC 2.0 compatible, the charger will ALWAYS charge at 5V. This particular charger indicates when the device has allowed it to shift into the 9V or 12V charging modes (but unfortunately doesn't indicate which). In either of those modes, it's 18W (which incidentally is about 4W more than the Moto "Turbo Charger").
I've seen a 30W charger on Amazon (which is the maximum, according to the standard), but it doesn't have the indicator. This is important to me, because QC 2.0 needs a full data cable to communicate with the device. Accidentally use a charge-only cable, and it will stay in 5V mode. It's nice to have that warning that you've done something wrong.
However, in this case... that indicator showed me that my Shield had a fantastic unadvertised feature (at least as far as I knew).

So no more words, i'm getting that charger.
Ps: Negative charge while playing, do you face it? It happens on games like HL2 and Sky Gamblers - Storm Raiders.

Seems you have a problem, mine doesn't take more than 4:30 to go from 15% to green light.

Actually, using the stock charger, it only takes mine about 3 hours to fully charge from being dead.

I don't think so
Correct me if i'm wrong but the shield battery is 6900mAh.Stock charger is 2.1A... So what you are saying is impossible.

Doesn't charging a battery faster degrades it? Like, the faster you charge it the hotter it gets and the fastest it degrades overtime? And the same can be said of the opposite: the slower the better for the battery longevity?

You're wrong, it's a 5197 mAh. Stock charger is 2.1A. Battery charge take 4 hours near to 5%, 3 hours near to 15%.

Yeah, high amperage kill your battery faster, take care about "quick recharge" charger. Try to avoid long charge too. Don't forget : 1 cycle on Lion-ion battery don't mean 1 charge = 1 cycle. 1 cycle = 0% to 100%. So you can charge 20 percents at job, 10 percents in train, 70 percents at home.

See my post just up there. 6-8 hours is too long, maybe battery fail...

Thanks for all the replies guys, most appreciated!!
I have spoken to Nvidia Customer Care and I thought I would share what they advised me to try (which may or may not help others are experiencing the same issue), not sure if this will work or not, but at least it is something to try -
"We would kindly request you to follow the battery calibration producer mentioned in the steps below, observe the device performance and let us know the result.
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the Wifi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup.
For better battery backup and optimization, you may also consider following steps.
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster. "
Fingers crossed this helps.

Your charger is faulty I believe, same as mine which Amazon and Nvidia themselves said was faulty and I got a partial refund due to that. I would suggest you to get some other charger, that charges at like 2.1A as they charge the tablet ridicolously fast (about 2,5 hours from 20%) and I'm finally able to play games while charging too (however, then it charges at a slower rate).
I made a thread about this not so long ago:

[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.

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!).

Battery Estimate declined significantly seemingly after using USB headset adapter.

So I got an adapter to use a wired headset with my phone, it's one of those that allows for both headphone use and charging, though you need to plug in both, but I notice after I tested them out, my estimated battery drain declined all the way down to 9 hours remaining from a charge of 89 percent.
It used to be anywhere from 23 hours to a whole day, did I just break my battery? I'm not in a position where i can replace it if it goes wrong, especially since I just got this a month ago.
Checked it and it doesn't show any apps sucking power, I also disabled various bloatwares to make sure it would run smoothly.
I only had this phone since December and I made sure to charge it when needed, keeping it at around 40-80% charge as much as I could.
Phone is a OnePlus 8 5G, battery drain before was about a whole day before I needed to charge unless I were watching videos, and even with that it still lasted a good while.

It's not a good idea to use and charge the phone as it disrupts the charging curve*. If the screen is off and the device power usage is minimal like listening to music on bt does not interfere with normal charging, at least on my 10+.
Give the phone it's quiet time to charge.
Limit charges to 80% preferable 70% and discharges to 30% preferably 40% to maximize battery life.
Avoid going under 20% or full charges to 100% as it needlessly stresses the battery.
Li's love short, frequent midrange usage like from 40-65%
Li's hate high heat (>100°F) and high cell voltages ie >90% charge.
Avoid charging below 72°F as it can cause Li plating which will permanently degrade it.
Never attempt to charge if below 32°F.
*if you're drawing power whilst charging the device you can not gauge its actual battery capacity. It will charge much slower or maybe not at all.
Stop that you!
Take a 10 or 15 minute break and let get it take a charge.

It's not a good idea to use and charge the phone as it disrupts the charging curve. If the screen is off and the device power usage is minimal like listening to music on bt does not interfere with normal charging, at least on my 10+.
Give the phone it's quiet time to charge.
Limit charges to 80% preferable 70% and discharges to 30% preferably 40% to maximize battery life.
Avoid going under 20% or full charges to 100% as it needlessly stresses the battery.
Li's love short, frequent midrange usage like from 40-65%
Li's hate high heat (>100°F) and high cell voltages ie >90% charge.
Avoid charging below 72°F as it can cause Li plating which will permanently degrade it.
Never attempt to charge if below 32°F.

I don't use it when it's charging, it's a OnePlus with warp charging so I let it sit until it's either full or usually at around the 80 range.
It seemed fine until I tried using this headset adapter, I don't know if these can break the battery in any way so i don't know if just using this messed something up.

If you have fast charging just use the standard fast charging cable to charge it not the daul use one.
The latter may not be recognized by the phone for fast charging, if so it will default to slow charging.

Warp Charging works yeah, I'm returning the headset cable and replacing it, since i don't know if it messed my system up, and aside from that it's clunky to use.

It was this thing.
do you think my battery is just messed up at this point or is it fine? Battery estimates used to show 23 hours to a whole day, but now it's down to 9 hours so I don't know if that messed up my battery somehow.

I doubt it messed up the battery especially if it's been only a week or whatever.
More than likely it's a misbehaving apk(s) causing the drain.
If your battery's rated capacity is 1000 mAh and you're only getting 400 mAh out of it, then you have a battery issue. How long it can run doesn't reflect battery condition unless the load is the same as before. So you need to scrutinize it further before making the assumption the battery has deteriorated.
I use two overlay apks (Accubattery is one) that let me see total current draw in near real time. I'm running Pie and doubt these will run in Q.
At idle my draw is an average of 150 ma or so with lows going down to 79 ma. If I see it averaging 300 ma with spikes going to 800 ma at idle I go looking for the cause.

How's your battery capacity holding up after some use with the 65w charging?

Looking at buying this phone but I'd like to know how the battery life holds up over time with the fast charging. What kind of screen off time do you get after 6 months or a year of using the phone?

I've had it for a year and I have charged it with a slow 1 Amp charger every night. I only use the 65w charger maybe once a month. I haven't had any issues.

I've had the phone for almost a year and I charge it with the 65w charger every day. No issues, battery lasts for as long as it did when it was new.

@baxtex
Yeah I just got my 8T today. I did more research and found out they use multiple temperature sensors that will trigger the device to charge slower if it's overheating. They also use 2 batteries in the phone to prevent this heat from happening under normal charging conditions. If it was in the sun or in a very warm room or something I'm pretty sure it would throttle itself based on some of the reviews I found on it. You might have to have adaptive charging on for this but I would assume it's just more aggressive than the regular protections. Pretty sure you could explode your battery with 65w charging in direct sunlight on a hot day. Anyways I think 1A charging is overkill for protecting it. 1A is also not actually not a measurement of current unless you have the volts also. If it's 5V which I think all usb is but I haven't checked since usb-c came out that would be 5 watts. I guess if you leave it on that overnight it doesn't matter though not like it'll hurt anything.

Question Help with the charger - Problem

Hello!
It's been a while since I don't have an Android device (Iphone user lately) and I'm buying this beauty these days.
I have two questions: First, right now the 45w charger is out of stock so should I buy the 25W instead just until I find the best one (expend money).
Two: How shall we charge this device? All night? Just 2 hous like Iphone? Please help me out on this.

25W vs 45W is really just a matter of the time it takes to charge the phone. And right now, available evidence suggests that its not worth it. As for how to charge it? All night is fine, as the phone will stop charging the battery when it is fully charged.

does the phone will stop charging the battery when it is fully charged?

Yes, that is always the case.
I would recommend buying a 45W (or higher) USB PD PPS power supply. That will work on Samsung devices. But keep in mind: it has to support PPS to allow voltages between something like 5V, 9V, 15V etc. If it is only USB PD, it will only charge at 15W.
I have the Anker Nano II 65W that has PPS, but there is also a 45W version. But that is just one option, there are plenty of other products out there that support 45W USB PD PPS

LAtest equipment come with a battery health function it basically charges fast up to 80% and then slowly charges the remaining 20% to extend battery life. Once at 100% it won't charge at the same level, reducint the current/voltage.

I really don’t want to damage the battery like it happened with my iPhone (1 year and 89%).
That’s why I’m asking!
Please post your own experiences.

The worst thing for mobile phone batteries is heat. So running the display all the time and gaming are probably the things to avoid. Which unfortunately...Is what most phones are being designed for these days. So don't let the phone get hot, and try to keep the charge level under 80% if you want the battery to really last. But batteries WILL degrade. There is no way around that. The best you can do is try to limit the damage.

Two things kill the battery: heat and high/low voltages
In an ideal world, the Li-ion battery is at around 20°C and stays at around 3.8V.
Use the slowest possible charger whenever you can (5W e. g.)
Avoid fast charging as often as possible
Don't charge past 80% and don't let it drop below 20%
Don't let your phone stay at 100% for too long. Nothing will happen but the high voltage will degrade the battery (like if you leave your device plugged in every night).
In theory you shouldn't charge your device when it's hot and so on but I mean if you live in Spain for example and it is summer. What else are you going to do? So avoiding charging the ambient temperature is too high, is something you can't really do. (Yeah, in Spain most homes to have AC but you get the point )
I have taken care of my OnePlus 7T Pro's battery since I have received it 2 years ago. According to OnePlus Diagnostic it started at around 97% health (new device) and is now at 93%. I almost never charge above 80% and have a Tasker routine to only let it stay at 60% over night and charge to 80% right before my alarm rings. I use ACC (Advanced Charging Controller) for that. But it requires Magisk.
That might be a bit extreme but I have only lost 4% after 2 years and countless battery cycles. Keep in mind that every now and then you should go from 0% to 100% to let the system calibrate the battery so that it accurately reports its charge. This is the only reason why you should do this so that the system knows how much capacity the battery has. And if you mostly stay between 20–80% all the time, it might think that 80% is its max charge and start misreporting the percentage.

Thanks for all that great tips. I think I won't ever buy an extra fast power charger, I'll use a normal one...

yes, enable fast charging and limit to 85%
