Hi this is my first phone that is capable of wireless charging. I have the pixel stand but I only like to charge my phone to 80 not 100. It greatly extends the overall life of the battery. Is there a way to make it trickle charge so I can just put it on my stand and go to sleep? I thought I read somewhere if you use a different wireless charger other than the pixel stand it wont charge at its max 10w. Is that true and can anyone recommend a wireless charger stand that would trickle charge my phone?
The phone mostly decides how charging is done. This is the same for wired charging. The charger has no idea how charged the phone is, so it doesn't know when to stop. Even if it is very slow, it won't stop until 100%.
Your phone would need to be rooted in order to have an application control/stop charging at a certain point. (I use Battery Charge Limit with custom settings)
Alternately without root, there are chargers with Bluetooth that can pair with an app to disable charging at the charger level when the app tells it to stop.

Two methods I've tried without root on my Pixel 4 XL:
Go-to Google Play and search "Chargie". This method requires a Bluetooth connection with a USB adapter inline with your charger. I tried this first but found it unreliable and a battery drain. I emailed the developer a few times and asked for improvements with less liability on battery. I'm not sure where that project has progressed since but updates sound like it had improved.
Second method didn't require any additional expense because I had the resources already. This method uses Tasker (no root required), IFTTT and a smart switch of some kind compatible with Webhooks on IFTTT. This tutorial walked me through my first and still only Tasker task. Wasn't hard but took some dedicated time and just a little patience and persistence and motivation. The tut is mostly doable but I can't recall the particulars but Tasker helps helped me to put it together. Something about a default change where I couldn't find the suggested option? Doubtful anyone familiar with Tasker would have an issue at all.
https://www.reddit.com/r/pixel2/comments/7vnsmo/how_to_prolong_battery_life_by_using_smart/
This is the method I've stuck with since setting it up. It works and isn't a battery liability. I do get a slow command to release power so I adjust the command % cutoff accordingly (2 or 4%). I didn't use wemo but another smart strip that gave me individual control of its outlets. All credit to the original reddit author and Tasker. Props to IFTTT and Webhooks applet for bringing it together.
I figured I could keep the Chargie USB adapter for traveling away from home or in my car. But one solution I found for my car was to setup a smart watch notification for Accubattery. It works; I get a notification vibe on my watch and unplug the car charger. If I used the Chargie, it would charge to a point and stop charging until phone got to another preset discharge and charge back to the preset point, like 80%.
Good to have options right root. I've rooted my previous phones but with adguard, I took inventory of what I really needed and this was the one I really couldn't do without. Still not rooted. But got a working remedy anyway.
I suppose Accubattery notifications is a third option...

Thank you both for the suggestions. I have always used acubattery and would unplug.my phone. Now I do the same only unplug the pixel stand. The thing is.i like.some of the features.of the pixel stand. I don't want to bother with root and I understand that the phone is what controls the charging. I will be trying the Tasker and ifttt method. I do have a few.smart pugs from kasa smart so I will see.ifmthey work if not I'll try a different one.
I did read somewhere when the pixel.stand first came out along I th the pixel 3 that the pixel 3 had to be on the pixel stand to charge rapidly and the 3rd party chargers were just a trickle or just not rapid. But I do not know if they have since fixed that with and update or in the pixel 4 itself so I will be trying the above instructions again thank you

There's still likely a way to also slow the charge with Chargie or swapping the power block that your Pixel stand uses. It's likely using Power Delivery which is quite fast. The slower charge is also better for battery.
Qualcomm Quick Charge 3.0 is slower but a standard block may be 5V 1Amp. Accubattery can help comparing charging blocks for ideal charge.
What Chargie does is allow you to set a profile with max battery temp and limit charge capacity which will slow it down. You would need USB adapters for the Chargie; it uses USB A male and female connectors.

Yeah I felt how hot the battery got and did not like that. I could just use the pixel stand and not plug it in. The battery doesn't seem to get that hot when charging with just the wire. But I'm going to look into charge. I like the idea of limiting the battery temp.

I have the type c to a converter that came with my pixel 4. I also have type A to type C cables is that all I need or are you talking about something else? It looks like there is a Male type A for input which I guess would go to the charger and I cant see the other side but Im assuming there is a female Type A for output which would go to the phone/wirless charger. Is that correct? If thats the case I can use two usb A to C wires

Hey I got the chargie last night. Trying to set it up. I have the converter that came with my pixel 4 and I have a few a to c cables. It works great. That was a good call my friend thank you. My only issue now is the stupid pixel stand won't charge wirelessly with those a to c cables. But I have the adapters coming for both sides so will.be using the original charger hopefully that works.
Do you know what a safe temp for the battery is? It's set at 140 but that seems too high to me.

Wow, that is high. Maybe that's for discharge? But Chargie should use charge temps- see the table and article below for lithium batteries. I didn't recall what my Chargie was originally set to but when I charge mobile devices, I setup with a charger with multiple cables coming from a multiple output USB charger to my air purifier. The forced air coming out at its top cools my devices so I set it to 86°F
This is the max temperature recommended by battery college for fast charging to better protect the battery. I've not monitored it but Accubattery can- use the charging tab. Seems I could go lower with the circulated air.
https://batteryuniversity.com/learn/article/charging_at_high_and_low_temperatures
Edit: maybe Chargie uses an operating temp because it can be left plugged in to charge when it reaches your preset capacity. This is handy for a laptop or tablet on a plane plugged in to charge; charge to 80%, discharge to 45% and charge back to 80% without having to unplug or monitor battery capacity or temperature. Set accordingly and be worry free. 140 seems high but charging when using increases temperature. Set too low and it may not charge until you standby the screen to take the load off the battery. 140 so is max operating temperature but I don't feel that safe in that range. I'd standby that device rather than charge at that temperature. But the device is likely using that temperature range by default.

I haven't checked what the temp is when charging. I did notice it is hotter when using wireless charging. When chargie is not charging there is no power going to the device because it's basically just a Bluetooth switch. When it reaches it's charge it turns off the power. I have to test to see how long it takes to cool off the battery and that's how I will determine my discharge percentage. Give it enough time to cool off then charge back to 80.

I agree. That's the likely intention for a phone. But can also be modified to remain plugged in while on a plane. But that's likely a tablet or laptop use.
The profile options were a factor in selecting the Chargie. I still use the Tasker method at home though. And I don't know if still necessary but I always force closed Chargie after using to keep the battery liability low.
I'm interested to know how useful and battery minding you find your new Chargie.

Sorry for delays from Amazon. I've had a similar from a third party seller in New Jersey. Order was supposed to arrive just before the stay at home order went out- FedEx didn't pick my order up the day the seller said it had shipped. Still sitting there waiting for FedEx to pickup. Seller says FedEx told him they are doing their level best to complete shipments. I don't know about New Jersey but I see delivery trucks every day in my state.

I have been getting deliveries with no problem for the most part. At least once a week or more sometimes (My wife is furloughed and loves amazon) Im in new york and I do see FedEx and UPS all over. UPS had a problem last week that they are still trying to recover from. I dont know what it was but a bunch of stuff was delayed because of it.
Anyway I have spoken to the owner of chargie about a few things. He got back to me right away. The chargie is not compatible with the pixel stand in fact the pixel stand is not compatible with anything other than USB c to USB c. A USB A to USB C cable will not work on the pixel stand. And as it turns out that a good thing. The heat created by rapid charging is really not good for the battery. I now have my chargie plugged into a USB type A cube that charges at 1.5a The discharge is set at 3 and the charge is set to 80. So it discharges to 77 actually when it hits 76 is when the chargie turns on and turns off when it hits 81. The charging temp seems to stay around 90 F. Thats not bad the regular operating temp is around 85.So its really only going up 5-8 degrees when charging. I use accubattery for all my stats. My current screen on time is 12 hours and 30 minutes! Thats fantastic if you ask me. And currently my batteries health is being reported at 101% So almost no wear on it so far.
I want to thank you for pointing me in the right direction I never would have found this without your help. Its nice to see that there are still some good hearted people on XDA. I was around when it was still relatively new and everything I know about android I learned from the great devs and other enthusiasts. And I like sharing what I have learned and what setups work for me. I feel like I am giving back to the community so I will always share my feedback and what not.
101 % battery health is great. Doesn't appear the heat has effected your battery, not yet at least. I started limiting my charge to 80% capacity when I saw the health stat start dropping. I'm still at 95% battery health; if I recall correctly, I started limiting when health dropped to 97%. I did see 100% early when the phone was new.
Chargie was not reliable early. I also emailed the developer and he compelled me to join beta and send some logs. I let him know what I was expecting: not run continually and only connect when charging. I believe someone had said that Android can no longer uses USB plugging as a trigger? I don't know if he sorted that yet or not or just can't? But it appears in updates, he's made progress. I hope he does. I just keep the app updated and forced closed until needed again. Won't travel for some time now. But Accubattery alarm notification does well with my Fitbit Versa 2 to notify with a vibration on my wrist when wireless charging in the car reaches its set point.
Sometimes I forget and leave my phone plugged in. Tasker still has me covered if plugged in all night.

Whenver I'm charging via wall charger or USB my captivate is super duper SLOOOWWW. It takes forever to switch screens, the keyboard doesn't function correctly, and my bluetooth won't sync. As soon as I disconnect the charge everything is back to normal.
Any ideas?
No replies? Sooo...Am I the ONLY one?
be patient for answers here
Ive noticed it charges slowly but I have not noticed it being slow while charging.
The theoretical output of the charger is .7 amps, and thats not very much in the smartphone world these days. When I am using it and it is plugged in, it charges roughly a percent every eight minutes. The .7 amps must be just enough to cover the phone being on and in use.
I am currently looking around for chargers in the 1 amp range. My old tilt 2 charger works great for that and i definitely saw a charge time improvement. I would love to have one with a greater than 1amp output but I dont think you can find them anywhere
Are you running SetCPU with set profiles ?
If Yes : that is the problem , adjust profile.
If Not : must be something else, not a common behavior.
I read this on another forum but someone mentioned changing the default usb setting from Kies to something something else may help.

As long as the output is 5 volts, you're o.k.
My captivate runs the same while charging but the actual process of charging the phone takes forever it seems. I've only had it a couple days now and I have to get used to killing some tasks while charging because I actually think the battery life was decreasing as it charged.
Incidentally, the display is the real killer on the battery...most tasks don't really eat as much battery life in comparison.
Recent Nokia chargers will work with a slight mod to the plug where it fits the phone,
After Pimping out my phone it works fine while charging now. Yea screen eats up like 82% of batteries resources...OUCH!
Just search for Motorola P513 on Amazon. Rapid rate car charger! And, belive me, it's perfect fit! Now on sale for $5.85 (was $29.99).

for those of you who have a old iphone/ipod touch charger block, use that instead.
its rated for 5V/1A output, higher than the 5V/.7A output on the default samsung charging block.
that should charge the phone much faster
I have the same issue with charging, no matter what charger I use (iPhone, Tilt, USB), it's all VERY painfully slow. I've been as high as 1% per 6 minutes (rare - when using Nokia charger (1.2A I believe) to 1% per 13 minutes via USB.
I'm thinking it might be something internal to the actual phone. The iPhone didn't take this long even with USB charging through a computer or LCD monitor. Heck, the iPhone on average was 90 seconds per 1% of battery. I could have a nearly dead phone and be fully charged and ready in less than an hour and a half.
Anyone else think the same?
yea i think it might be something related to the phone indeed. this is, in my opinion, the biggest problem. i'm always on the go and i depend on my phone so much that if it doesn't charge fast enough i'm screwed.
let me make a post in the galaxy s forum and see if there's battery charging problems

which thread is that? I'm curious to track that one as well. I have gotten 4 other people to purchase the Captivate from the iPhone and we are all on the same boat..even with a 1.2A charger from my N97 (which only lasted 3 weeks with me...but can't wait for the N8), it takes about 4 hours to charge the battery...something's wrong there. It shouldn't take less to drain the battery than to charge it!
I've had the Droid 3 for about 10 days now, and I've been encountering an intermittent problem with charging the phone.
Last night, I plugged in my phone so that it would charge overnight. I made sure that the connections to both the phone and the outlet were firm, and upon plugging it in, my phone's battery icon and lock screen both indicated that it was charging. However, when I woke up this morning, I discovered that the battery had actually continued to discharge overnight. Despite this, the battery icon and lock screen both continued to say that the battery was charging.
I've run into this problem three times this past week. It's entirely possible that I just have a defective device, but I wanted to check and make sure that nobody else was experiencing this issue before taking it back to Verizon.
Check the task manager for programs using lots of cpu. I've found that using google maps nav in the car dock while charging still in fact uses more power than it could charge. Your issue is with the screen off though so check for background apps.

I have had this problem 2 times and I have had the phone for about the same time. I plugged it in at like 40% watched a movie screen never came on till the movie was over I looked at my screen and the battery was at 11%. I was thinking maybe just a bad connection untill I looked at the notification bar and it said it was charging!
I just got my Droid 3 yesterday and last night, the first night of use, it did the same thing. Even if I go into battery usage and look at the graph it'll say charging but the power level will be going down. Very frustrating.
A Verizon rep I spoke with recommended trying a different charger. Sounds reasonable enough, so I'll give that a shot and post back after a few nights of use.
What is the current rating of the chargers you guys are using? (i.e. 850 mA, 1 A, etc). A good rule of thumb is not use anything less than 1 A (1000 mA).
The Motorola-supplied charger is 850mA.

This sounds logical. I had this same problem two phones that happened to have a slide-out keyboard (Shift, G2) and the problem vanished when I used a different charger. I just read today that 100s of people were having this problem today in a news feed.
I was having the issue too, so I used a 2A charger that came with my Huawei tablet...no more issues! (Charge time is about 1.5 hours too!)

I'd be careful about using higher amperage chargers. Don't want to be burning out the charging circuitry. Not saying you will.. just be careful using a charger not designed specifically for the device.
Apparently the new Moto LiPo batteries have another level of overcharge protection. To be safe, I'm going to use an ohm-meter about once a week or so to check the internal contacts (a higher ohm rating would suggest damage).

That's not the one I have, I'm using the USB-output charger from the S7 SLIM, then the Moto supplied USB cable.
Well, it's been a few days, and I haven't experienced the problem since switching to a different charger. Granted, the problem was intermittent, so it's difficult to know for certain if the charger was in fact the issue, but I'm content with this solution.
I've been using my iPad's 5.1V 2.1A charger without issues for a few days. It charges the extended battery from 10% to full in a little over an hour.
That's the dual-core proc for ya. Wonder why the Xoom uses a proprietary charger? dual-core devices nom battery.

No? Dual core is more efficient, it shuts down one of the processors when it's not in use. Dual core means nothing about power efficiency. As a matter of fact, it can have an advantage. Each core uses less power, and combined, they can use less power than a similarly powerful chipset.
I've also run into some issues on my 5 day old Droid 3. It seems to be when disconnected from the charger. I have two regular Moto chargers for this, and tried a 1A HTC charger, which this thing will not charge from.
I tried using different micro USB cables, which didn't help, either. I was trying to move the phone around while charging, and seemed to encounter the issue. Either it's a connector issue for the mUSB, or the (especially short and stiff) charging cables have broken conductors inside, and we're getting a bad batch of cords.
Possibly the D3 has its own issue with charging, but I didn't have a problem until this morning. regular mUSB cords won't work for me at all, as I've tried all I have.
Given this issue, I'm wondering how widespread this is, and if it's something to take the phone back for. I took me a few hours (over 3) of waiting and fiddling with it, but it's at least charging now.
I had this issue to. I used a different charger and cord to charge my phone at night woke up the next day no charge. I went to work pluged in to my wall charger and still no charge. I did a factory reset thinking that might work but it did not. I was going to take it to a verizon store after work so on the way there I pluged in to my car charger an it started to charge so I skipped the store. When I got home I used a different cord and wall charger and it also worked. I did notice that when I plugged in the night before that a small little white light was lit up for a second in between the charging port and hdmi. I know there is a light there but never seen it light up before. So maybe that was behind all of this. Not had a problem sense.

The amperage you see stated PS units has no effect on your phone. That's not how many amps leaves the unit to charge your battery. That's how much the PS unit can handle as a draw. In reality the reason the stock ones are only 850 only means that the manufacture used spec parts for the PS unit. i would think that Motorola's minimum spec was 850 and so that's what the PS units manufacture used.
The higher the number means nothing other than you can bet the 1AMP one is going to out last the 850.
Of course the last statement is highly speculative because i have no idea what the amp rating for the phone is. But what i do know is that all the parts are made in china and you can bet they are not going to overbuild anything.
If the amp range is 675-832, which is the number I would expect then if the phone draws more than 850 for an extended period of time the units internal fuse could blow. Unless of course you purchased a third party unit that has an external fuse. Then you can jsut replace the fuse and not have to worry about going out to buy Chinese garbage. lolz
but then again i bet this Droid 3 is made in china, oh well. I like it anyway
For cryin' out loud, I'm tired of watching my battery drain while plugged into the supplied USB charger. It's ridiculous. I've never owned a portable device that discharged under normal use when plugged into its supplied AC adapter. If I want to spend 15 hours a day playing Angry Birds, it should be possible when I have a power source which is virtually unlimited. Twice, I've started the day with a full battery, had the device plugged in to the supplied 2 amp charger all day, and had <10% left on the battery when I went to bed. (No, I don't actually play Angry Birds for more than a few minutes at a time but I do use the device a lot.)

Twice, I've started the day with a full battery, had the device plugged in to the supplied 2 amp charger all day, and had <10% left on the battery when I went to bed. (No, I don't actually play Angry Birds for more than a few minutes at a time but I do use the device a lot.)

I don't have that problem. You do know that your device will wait till it drops some percentage before it starts charging again. It won't keep it at 100% the whole time... Is meant to conserve your battery life

Let's pretend I've got just a little experience with portable devices. The standard is to float between 95 and 100% charge and just call it "charged" once it's bounced off 100% the first time.
Here's a test you can do that requires no time on your part. Set it up to play a long movie while it's plugged in. Look at the charge level after it's been going for a couple of hours. And you don't have to take my word for it. I'm hardly the only person complaining that the supplied charger is not capable of keeping up with the device's power requirements.
If you are seeing power drop during normal use while plugged in I'd talk to Google. You may have a defective unit. Mine doesn't do that and I regularly see 20+ hour days with normal use unplugged and usually with some video, browsing, games etc.
Take note off when you see the drop, how much you lose over a given amount off time and call Google and see if this is expected. I'm sure they will help. They have been very responsive when I've called.

I will watch like 1 hour of Streaming Vid's and loose like 4-5% while plugged in.
100% brightness causes my device to use more power then what's being supplied from the wall charger, and a few other people have confirmed similar incidents as well.
Max your brightness, and then go play a 3D game, while being plugged into the wall charger, and watch the percentage drop still
My tablet lasts a few days at least before needing a charge. I plug it in over night and it charges to full. I couldn't be more happier with it considering it is not self-sufficient.
Mine drops a few % per hour in use with the stock charger connected. Brightness at 50%, WiFi on, BT off. I'm not going to whine about it, but its the only thing that's not great with this tab.

Why do everyone seems to think that the POGO-charger would be able to charge the Nexus faster?
I've read on an Ipad forum that about 10-15 hours charging are normal (the Ipad 4 has a 42,5Wh battery), and their chargers give as much Watt as our Nexus chargers.
One thing is clear, you can't increase the voltage. That would kill your Nexus right away.
My Samsung charger I recieved with my Nexus 10 says 5V out and 2A.
5*2= 10W.
Isn't that the same rates that other tabs have, even if they got special chargers?
So, the only thing the POGO-charger could raise, is the amount of current.
Even if you had a 10A charger, if the Nexus cant use more than 2A, it wouldn't get anymore amps than 2.
If the kernel on the Nexus doesn't support any higher charger rates, then you cant change anything.
There is a reason why the manufacturers have set 5V as standard - to make it work together with USB.
Battery Specs: Samsung Li-Ion 3.75V 22.75Wh 9000 mah.
So, it's easy. If you had a 1W charger, it would take 22,75 hours to get a fully charged battery.
In theory, it should take 2,75 hours to fully charge the Nexus 10 battery, but we don't turn it off, we use it while charging, it uses background sync and I dont know what the efficiency rating is on the charger or the Nexus.
You know you could feel some heat on the back of the Nexus 10 after some usage?
That's some of the battery's energy that spoils into heat, meaning that there are power losses.
It's normal though, we don't have anything yet on earth that could convert 100% energy from one form to another.
You could compare it to a car, you need a cooler-system to remove the excessive heat from the engine.
Even if your Nexus is far more efficient.

Please do not speculate about how much current can go through the pogo connection. Speculation is worthless and helps nobody. The fact that the included charger only puts out 2 amps probably has to do with limitations of the USB connection. But I'm speculating. See how pointless that is? The fact that one connection is limited to 2 amps doesn't mean all power connections are limited to 2 amps.
And where did I say anything about increasing the voltage? I'm not an idiot and didn't suggest such a stupid thing.
As for temperature, that can easily be monitored during charging and the current can be reduced if it gets too high. You are aware that there is a temperature sensor for the battery, right?
None of which has a darn thing to do with my opinion that it's unacceptable to produce a device that uses more power than it can get from its AC adapter. If there really is no way to run the Nexus 10 at full tilt without supplementing the AC adapter with battery power, Samsung should have addressed that problem before going into production with this unit. This isn't a $150 entry level device. It's the Android flagship.

Please, you started speculating about a high-current POGO-charger that doesn't exist.
Sure, you didn't mention the voltage, but I ve seen comments about it before, so I just wanted to make it clear.
And I didn't say the temperature was a problem either, just that it lowers the efficiency of the charger and the device.
Samsung maybe didn't know there was a charging problem.
We've seen examples before that manufacturers don't test their products enough.
(ASUS Transformer with encased aluminum body, anyone?)
And I know, this is supposed to be a flagship, but what everyone forgets is that it's much cheaper than other brands.
I was looking forward to buy a ASUS TF700 with keyboard at almost twice the price as the Nexus 10 before I read about the Nexus.
Even if it doesn't justify the charging problem, you could try to adapt to the circumstances until there's a solution.
When I'm low on battery, I let the device charge and do something else for a change.

Edit: If you look at the pictures of the POGO-charger that's across the internet, the charger is still only 5V, 2A.

I have a nexus 10, nexus7, and a Tf700. I am noticing slightly faster charging on the n10 using the Tf700 ac adapter. The same is true when trying to charge my tf700. The stock samsung n10 ac adapter charges it slower than the asus transformer adapter. The same is true with my nexus 7 adapter. Ive used the n7 adapter to charge my tf700 and it was not as quick a charge. Meanwhile all 3 units are rated for 5v 2amp.

Could be possible the N10 charger isn't actually putting out 2A? Might need a multimeter or something to verify for sure though...
I am currently out of town so keep in mind I didn't have a chance to dig too deep but I've given the kernel a quick look through.
There is no such thing as the "high current pogo charger." The pogo pins accept 2A max and appears to be ~5V. The USB connector has the same limits.
I also took a look at the current at the battery to make sure the charger was being detected correctly. My 1A Samsung non-Nexus 10 charger seems to supply ~900ma to the battery which is as much as you should expect out of a 1A charger. My Nexus 10 charger supplies ~1600ma to the battery. This number seems slightly low but at least indicates the charger is detected correctly.
*If* the pogo charger does indeed charge faster, it will likely be because the pogo charger is able to supply some current that is asymptotically closer to 2A. In other words, it will not charger much faster than the USB charger.
On the other hand, the pogo charger will still be nice to have as it will allow simultaneous usage of USB OTG and charging.
Like I said before, I was unable to dig very deep because I'm out of town and browsing sysfs and kernel source on a tablet isn't the best experience. So, the info I found might not be 100% correct.

There are many indicators throughout the kernel but for brevity I'll post what I think is the most concise.
https://github.com/CyanogenMod/andr...ng/arch/arm/mach-exynos/board-manta-battery.c
Line 773-776
Sets the current to 500ma if USB is detected on the pogo or 2A if AC is detected.
Well if you're reading 1600ma using the standard ac adapter that comes with the N10 and possibly closer to 2000ma (say 1900ma) using the pogo, then that is 1/5 faster charging. In terms of time that is quite a saving.
Of course, that is all speculation
USB current limits
I thought I'd post this as information I found while doing a spot of light reading
The current specification of a USB 2.0 port can be a maximum of 1.8A. Within Constraints.
"Battery Charging Specification 1.1: Released in March 2007.
A usb charging port places a termination resistance between D+ and D- to allow the maximum 1.8A", meaning that at this current, there can be no data transmission.
This appears to be increased for USB 3.0 standard.
"Battery Charging Specification 1.2: Released in December 2010.
Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A."
citations come from documents here:
http://www.usb.org/developers/devclass_docs
As POGO pins do not have to follow any specification the only limit is the current the board & charging circuit can handle.
Look at the specs on the wall plug in unit. It's not a charger it's a 5V power supply and the charger is inside the N10. However the charger is setup determines the charging rate. Like mentioned above, it may not matter if you "could" use a 10A at 5V power supply.
Hey guys so lately there's been a lot of discussion about the pogo charger.
I've checked all the threads and more than the value of the charger, the forums are filled with shipping complaints.
I can't seem to sort out the opinions and real comments on the pogo.
As such, for those really on the fence about getting a charger (like me) I made this poll, since there was one on screen protectors to help people choose.
Any comments made, please make constructive opinions on if you have a pogo charger, if it's worth it, etc. (not on your shipping problems please)
Thanks!
I only bought it because I thought it would be able to charge my tablet while under heavy usage (1.7GHz performance gov + full brightness), and sadly it doesn't even seem capable of doing this.

I seem to remember somebody stating that under heavy usage they've saw a current drain over 3A. If your situation is the same, nothing is going to keep up with that which is over the max of the charging circuit. It's simple to test for that.
The POGO cord charges faster but stops during OTG usage, no ROM/kernel Dev's have tried to solve this issue so far. There may be another issue with cigarette lighter type power supply also.
Shipping just took time from Korea, now they have a US shipping source through Amazon.
I really like it, saves wear and tear on the USB. I charge at night, and never have enough time to use it that I run the battery in a day. The OTG complication is annoying, but liveable, and hopefully likely to be solved.
I like the reduced wear on the micro usb connection and additional safety of quicker disconnect if cord is yanked from tripping. I charge the tablet at night, so not too concerned whether charging is quicker. I would love to see some ideas on how to improvise a charging dock using this cable!
I think whether it's worth it totally depends on the reason you want it. If you want to use OTG while charging or to do data transfer, it's obviously a bust.
These are the reasons I'm very happy with it, in order of priority:
1) Saves stress on the USB jack, especially if dropped or banged against something.
2) Easy to click onto the N10 when I'm done reading an ebook in bed at night and I'm sleepy.
3) Charges a bit faster than USB.
If you're looking for a miraculously shorter charge time then it's not worth getting.
Definitely worthwhile ... it is one of the nicest accessories I've purchased in a while. I purchased it only for the convenience of not having to mess with the mUSB charging. It delivered. My charging graphs indicate that it charges at a faster rate than the mUSB ... just a small extra bonus.

^^ this.
I bought it because I've had occasions where others in the house have messed up micro-usb connections on phones due to using them while still plugged in - with this, there's no way of easily damaging it
And so far, so good! Would really recommend it.

Wow, max brightness ? I find the lowest setting really bright.
I did general usage on lowest brightness and it charged pretty good, IMO.
It was worth every penny and when they come back in stock at Amazon I will order another.
I use my tablet heavily throughout the day and found myself unable to charge it completely while I slept. Now using the stock wall wart and pogo it charges in a fraction of the time. Like I said, worth every penny.
Charges faster, but was it worth it for me? Still undecided. The main reason for me getting it was to plug a HD into an OTG cable and still get power to the device via the POGO. Unfortunately that will not work. The POGO will not charge when running OTG. Shame.
Back in stock on Amazon... Just ordered one tonight. I'm interested for two reasons. Slightly faster charging (not a big deal for me, as I generally plug it in at night, and use it much of the day), and I also like the idea of the pogo connector instead of using the USB socket every day. Should have it in 3 to 5 business days.
... beamed from my Nexus 10 to your planet
Just ordered one off eBay, should have it by the 20th at the latest. I spend a lot of time driving so carry the Nexus 10 around with me in the car and I've bent the USB plug on the cable so though I'm better off getting the pogo charger incase I damage the USB port on the tablet
Answer- Yes it is but...
Just got the pogo cable on Friday and did some testing over the weekend and have some results and observations.
I ran my N10 down to 10% Saturday and plugged in via the pogo cable at about 11:30pm. . When I checked Battery Monitor Widget the following morning it showed fully charged at 4am. Total time 4.5 hours. Max charging rate was at 1916mA and tapered to 415mA.
Sunday I did the same, (11% and 11:30pm) and used the USB cable. A check of BMW showed the N10 fully charged by 5am. Total time 5.5 hours. Max rate was 1559mA and a taper to 420mA.
So, an hour faster. Not huge, but significant. Overall I think the important thing with the pogo cable is that it will charge as you use it. When I plugged in with it before I turned the screen off I was showing a net charge, while with USB it continued to discharge, albeit slower.
Both of these (admittedly unscientific) tests were done with the OEM charger and USB cable.
The pogo charger is a great way to save the USB port of the Nexus 10 if you have young kids. Since the pogo charger is magnetic, there no way to damage the tablet when a toddler yanks it off a desk while its charging. I am very happy with my pogo cable. Bought it off amazon and got it in 2 days.

It would be nice. I have an N7 but haven't bought a charging pad yet because I didn't feel I'd get enough use from it. My N7 battery easily lasts me a full day and I just throw it on the charger at night. No big deal.
I use a Moto X right now and tether my N7 to it on my daily bus commute (~2 hours each day) and I usually need to give the battery some juice before I leave work to have enough for tether on the ride home and the remainder of the evening.
When I get the Turbo, it will easily last a full day. I don't think I'd ever really need the full two days of battery life, but it would be great for long days. My Moto X right now can't make it through an entire day with my usage. I know I'm probably above the bar in SoT (usually 3.5-4h), but I average about 13h, according to GSAM over the last 8 months. Could use a nice big battery to keep me going for 18-20 hours.
I guess it does have wireless charging...
The new DROID comes with a turbo charging feature so when you’re low on battery, a 15 minute charge can get you up to 8 hours of use. DROID Turbo comes with the Motorola turbo power charger in the box at no additional cost. And for added convenience, the new DROID is wireless charging capable.

Awesome..thanks for that
Semi-related.. Can anyone suggest a nice charging pad? I've looked at them for my N7 before and the prices seem to range pretty widely. I understand they charge pretty slowly.. but are they all the same for speed? Does the device need to be perfectly aligned in order to charge? Can I charge two devices at once (N7 and Turbo)?
I'm thinking I'll throw a pad on my desk and one at home, either in the living room (coffee table/end table) or bedside table.
There are some features of a phone that you appreciate more when you have them than you do when you read about them. An example might be high speed charging, their are a few technologies out there for this but the bottom line is when you have it you really come to like it. Its very nice when you have forgotten to charge your phone and you suddenly decide to go out to be able to get a charge on it that will see you through in the time it takes for a quick shower. When it was new and I first read about this it sounded good but no big deal, I usually make it through the day fine and charge over night. Now that I've had it though I really like it.
This is kind of a long way to get around to it but wireless charging is the same way. Its very nice to simply have the pad on the night stand or wherever you may put it and drop your phone on it without having to plug it in. It seems like nothing much but once you get used to it having to plug in seems like a bit of a hoop jump. One benefit of wireless charging that often gets missed is port damage, I have had more than one phone in the household that met its demise by tweaking the micro usb slot so that it either wouldn't charge or couldn't transfer data or both. My understanding is we will still have to plug in to get high speed charging but the ability to do both if we want is a very good thing in my mind.

Good points. I held off on a pad for my N7 because the battery easily lasts me through the day, two if needed (I usually charge it every night, though). Even though the Turbo probably wouldn't need to be topped off during the day like my Moto X would benefit from, it would be nice to have the option. I agree on the Turbo charger too. Great in a pinch if you are at an airport or something and just need some quick juice for a flight or something.
3.9Ah batt's gonna take a long time to charge with a 700mA limit though.
Should be OK overnight. Then again if it's only discharged to 60% when you start it shouldn't be hateful.
Yeah, wireless charging works best where/when you are going to set it down for a while such as over night or when you place the charger where you set your phone in the evening. I used both, one on the nightstand and one on the end table by my chair. In the latter case it is quite convenient since you can answer a text or what have you and simply set it right back down and its charging again. This is why I think its a great feature to have both wireless and high speed by whatever name, they should complement each other well. I say should because I've had both but not on the same phone, I'm really fairly stoked about this handset for this and other reasons.
