Like the title says, my dad just bought a Nexus 10 and when he was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. Is it a defective unit? I know about the Pogo charger, but I'm sure he'd rather not spend $25 on it just to find out it doesn't work.
Any suggestions or ways to fix this?
Thanks.
edit: To make things even sound worse, it only charged 2% in 1 hour and 30 minutes.

All I know is that on mine takes about 9 hours to charge with the original charger. The first time I've charged it from 16% with my Galaxy SIII cable, and it took over 14 hours.
That does seem long. I have the pogo charger and it does charge faster.
Before you buy the pogo, are you using the chargers that came with the N10? When I charge my N10 from a laptop/PC, it does charge slowly. So make sure you're charging with the correct voltage/amps.
Good luck!
I'm having a similar issue since the OTA update to 4.4.2.
I'll try changing USB cables, but I'm not optimistic. I'm tempted to try a factory reset if a different cord doesn't work.

With Wifi on, NFC off, Location set to device only, bluetooth off, screen off, using my Pogo cable I get about 22% charge per hour so from 0% to 85% is 4 hours. Whilst on Pogo if I turn brightness to full and sound full then charge is held roughly flat. I moved to Pogo from the supplied cable as when watching stuff even when connected it was discharging, so now I'm never really out of power unless I stay unplugged a long time (about 6 hours unplugged max on low brightness)

This situation happens when the tablet isn't even on, so certain settings being enabled are not the issue.
And for more info, he is using the charger that came with the tablet, so we've just decided that we'll just send it back and get a new one because the battery is obviously defective.

Have you tried a different cable/charger? AN hour to charge from 20% to 50%? Sounds about right to me. I always switch mine off when charging, I can live without when it' off. :good:

I think clearly a human error in the word chosen explains it.
Instead of "...was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable."
it would make more sense if written "....was charging it from 20%, it's taken more than a day to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. "
.... then the later post of its a dud and its been replaced makes sense....

Ahh, I see. Good call in getting it replaced. I hope you have a better experience.
here are a few points
1) the AC USB come with N10 charge up to 2A.
2) the mini USB limit to about 1A
3) if you use other mini charger, that 1A is even smaller.
4) N10 battery is HUGE comparing to all tablet out there. It will take a long time to charge
Solution: get the pogo charging cable that cost $25 (very expensive and can only use for charging), that will fully charge 2A to your tablet which should reduce the time to less than 4hrs given no other power hog apps running at the same time. It will charge slower if that power hog app running too. You can tell by how warm/hot your tablet gets when running such app.
btw, go look at the disassemble of the N10. That battle makeup most of the tablet. LOL

Agree, BUT once you get >85% the rate of charge intake drops. I can get to 85% in 3.9 hours using Pogo cable, but that last 85%-100% is slower. My battery meter sees one kink 85-90 another 90-95 and a slow crawl 95-100. As the battery is not taking up 2A >85%, all chargers, all cables, will largely take the same 85%-100% but the Pogo cable with 2A input will get you to 85% quicker.
I have moved to a dual 2.1A output PSU.

I know you revised the post but just looked at the link to the PSU you mentioned.
Note that $10 one is dual USB socket but only 2.4A total meaning if it is charging the N10 taking 2A it can only offer 0.4A to something else meaning that other thing can only be something like a phone. More importantly is the opposite if you connect a powerpack USB battery which takes say 1.5A or 2A then your Pogo cable cannot deliver its full capability.
The PSU I mentioned earlier is dual 2.1A both concurrently meaning it can charge the N10 and something else also power-hungry like charging a 2A input or 1.5A input USB battery.
There are PSUs out there which can do 4 lots of 2A concurrent, I didn't get one as they were getting chunky and personally prefer two PSUs, a 2x2A + 1A for total 5A which does my N10, my USB battery (2+2) and my phone (1) concurrently taking two power sockets.
Check the details of specifications of these devices, PSUs and batteries vary wildly.

Like many of you guys, I have custom built my own PC. Yeah, it's a little outdated with a Q6600 but it will do for a good year or two more. Good thing I bought a Quad Core. But anyways, getting back to topic, you guys should realize that the Power Output of the front two USB ports are not the same as the USB ports that are in the back. This is a fact as far as my system is concerned. I know because I use a Lacie External drive which will only power on with the rear USB ports.
If you charge the SGS with the included wall charger, it will charge up in about 4 hours. When I leave it on my front USB port, I would wake up in the morning only to find it 60-70 percent full.
PS - I am amazed by the battery of this thing. Here is the break down. I fully charged by 1am. Took it off... then started using it quite a bit till around 3am ish. When I went to bed, the charge was at 72 percent. I work up 6 hours later and guess what, it was at 69 percent. Pretty neat.
The USB 2.0 only requires that a motherboard provides 150mA to a single port (& 500mA to 5 ports). Where as a chargers don't conform to this standard and provides a much higher charge, which charges your battery much quicker.
Only use USB if you have nothing esle.
The wall charger that came with the SGS is a 700mA. I just ordered a 1000mA wall and car charger.
The more I use this phone the more I am amazed by it. The Battery life on this thing is really great. It's already been close to 12 hours (11:30) and the battery is now finally at 49%
I've used this phone quite a bit and the battery held up really well. I used Let's Golf, Navigation, Armored Strike, Calls, Texts, Gmail... Good stuff.
So your telling me if i get a charger with more mA it will charge faster? Where can i get a bigger mA charger.
I don't know, but my battery charges fast as hell. It goes up about 5% in 20 minutes.

It will do neither.
read this. Gives some basics on Li-ion batteries. link
Essentially these batts can and should be charged at 1C c=capacity. Our batts are 1500mA so we could and should charge at 1500mA.
Slower charging is fine but these batteries rely on circuitry recognizing a drop in voltage to turn the charge off, or down to a lower current as to not damage the battery. If you charge at a higher rate the drop in voltage is more obvious than with a lower voltage and harder to miss thus less chance of an overcharge and battery damage. Added bonus is the battery charges quicker
Over charging is the killer of batteries. Overcharge occurs more from circuitry missing a change in voltage and failing to terminate.
Hope this helps.

How...? I am on my third Vibrant and i last 6-7 hours...
Well... I completely stopped charging my phone with the wall charger and I am now just using either my car charger or USB and i've noticed my phone over the last two days has probably doubled in being able to hold a charge. Today I made approximately 2 or 3 30 minute - 1 hour calls, used the internet approximately 20 times for about 5 minutes each time and used SNESnoid for approximately 1 hour straight and my battery was at 40% after a 10 hour work day, not too shabby. Not to mention I also don't get that annoying 10% drop within 10 minutes of unplugging the phone anymore
I've seen a ton of other battery tip's but I've yet to see any actually say stop using a wall charger all together. Here's to hoping this helps someone
Lol thanks for the tip. I highly doubt this is anymore then a placebo but good luck to whoever tries it. Not calling you OP I am just finding it hard to believe.
Furthermore, have you tried reseting your battery stats. I mean the initial 100-90 percent drop you are calling to quick sounds like its the fault of bad battery stats. If you need a link to how to reset your battery PM me only because I might not check back to this post lol.

Hmmm... I don't think that USB/Wall would actually make a overall difference in battery life but it could be that it doesn't "idle the charging" when you hit close to a full charge. So you're probably just getting the extra 5-10% that you mentioned.

I know for a fact im getting the initial 10% but I looked at my battery today at 12:40 tonight before leaving work thinking "ahh crap I haven't charged it it's got to be at, at least 5-15% and nope, it was exactly 39%, I was amazed. Talked to a girl for about 40 minutes on my drive home, talked to another friend for 5 and battery dropped to 35%
I've noticed this as well. Days that I've only used my moto car charger, the battery (even the cheap ebay ones) seem to hold the charge better, which I thought was strange, because you would think it would be a worse -maybe equal- change.
Charges more slowly and fills up more?

That's my theory
This is the case with most batteries, and I thought it was common knowledge with Li-ion. The lower the current you charge with, the better the charge.
Using the higher amperage wall charger lets you hit the voltage peak quicker but, the topping charge will take longer. A lot of car chargers are just as high amperage as wall chargers.
Other things you can do to try maintain the capacity of the battery over the course of its life:
-NEVER let it get hot (whether from heavy usage or keeping it in a hot car or the sun)
-never deep cycle (totally kill the battery)
-try to keep it between 40 - 60% charge for most of its life (Li-ion batteries do not like being at full charge or no charge)
Doing any of these things once will not destroy the battery, but by the 500th charge cycle, you can bet your ass it will.

Sounds like my kind of job! Seriously, I use USB (through a laptop) and car chargers almost exclusively and I have no real complaints about battery life. And by that I mean it gets me through the day, which is all I've come to expect from phones for the past few years. But I did happen to use a wall charger last night, and I have JuicePlotter active, so I did some checking.
Comparing my last overnight charge using my laptop's USB to last night's charge through a wall adapter, I found that the charging was actually faster through the laptop. I see that the charge tends to drop off as it approaches 100%, so I took pairs of points from uniform sections of each plot for my comparison:
Laptop USB:
44% to 82% in 41 minutes = 0.927% / min
Wall:
63% to 91% in 37 minutes = 0.757% / min

As far as for droiddev... this is my first phone where charging it from different devices gives me different results. I don't see where it would be common sense, Li-ion batteries are not supposed to not have these memory leak/hold issues like past batteries. A charge is a charge to li-ion batteries, but not in this case.

Not sure what you mean, but you will get the most life out of your battery by charging it short spurts at a time over USB. Read the article I linked to and you will see what I mean, but you can get the best charge into your battery by slowly ramping up in steps with a low current charger.
If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)
I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..
It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)
I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.
I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:
http://www.monoprice.com/products/p...=10826&cs_id=1082602&p_id=6766&seq=1&format=2
My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
Just wondering, how long does it take you guys to fully charge (From anything below 20% to 100%) your nexus 7? Because I've seen a few posts about battery related problems, and personally I think mine chargers slower than it should.
Also, when I use a wire to extend the charger, it's as if it wont charge, for it to fully charge i'd have to leave it on for hours without use, Since they're aren't any plugs where I'd usually sit to use it, I need to move somewhere else cause the wire is quite small.
For example, I've had it on charge since 2PM today, when I plugged it in it was at 14% battery, now (4:20 PM) it's at 63%. This has been without use, just sitting there charging. Plugged in via the charger and wire that come with it, to an extension with 3 other plugs in it.
I received my N7 with about 40% charge and it seemed like it took a really long time on that first full charge. It has been better since. I have heard if you are not using the original cable for the N7, it will dramatically increase the time it takes to charge and it won't show the charging icon. The supplied cable is USB 3 and your other cables are most likely USB 2. You might want to buy a 6 foot or 2 meter USB 3 cable for convenience. Also, use the original 2 amp charger it came with.

Well, that explains why the extender doesn't work, but I haven't been using that to charge it since I noticed it slowed it down allot. I've only been using the stuff it comes with ever since I noticed that. Still VERY slow though, it's only just reached 96% since starting charging it at 2am. so it's taken 5 hours to get from 14% to 96%, pretty sure this isn't right.
I've collected some data on N7 charging and cables issues here.

My completely drained N7 (<1%) takes approximately 3 hours and 49 minutes to completely charge it (N7 powered off during charging).

Which charger do you use?
And good to know it isn't a problem with my nexus I suppose.

OEM charger and OEM cable.
Like a lot of people I charge my phone over night, but with the 6p I wake up in the morning (after a good 8hrs) and its sat on 96-98%. Even though it still says charging.
It's no big deal but when I unplug and plug back in it charges to 100% relatively quickly.
Anyone else see this? I'm using an older charger (from my nexus 4) so may try the proper one tonight.

Isn't this normal behaviour? Most phones stop topping up the battery even when connected on the charger to avoid wearing off the battery.
I used to have my HTC m7 connected overnight to the charger and even though it showed 100℅ in the morning, as soon as I disconnected it from the main the indictor would drop rapidly to ~95℅ which indicated the above behaviour.

I've not seen it before. My galaxy s6 always came off charge at 100% as did my nexus4 and the 5x I owned briefly.
If this is normal and happens to other 6p owners I'm happy with that

Mine is doing this as well. It seems to charge to 100%, stop charging, and not run off power at all. Since I use sleep tracking, in my case, I usually wake up to about a 90% charge. This is the first phone I have seen do this -- they usually charge to 100% and keep running off the charger. I haven't tried the stock 3A charger yet, as there really is no need for a quick charge overnight.

How in the world are you using an old charger on a Type-C Connection? (or are you using a converter?... if so, that may be the reason)
Just using a USB A to USB C cable into the power brick from my old phone.
Pretty straightforward really.
I'll try with the proper charger at some point. It's not a big deal.
Mine hasn't done that. Got it Thursday and it's had a full charge each morning. Using the supplied charger
normal behavior. it does that to protect the battery.
Every phone I've ever had charges to 100% and stays running off the charger to stay at 100%. Last night (my first night with the phone) I plugged it in with 31% and woke up with it at 81%. It clearly charged....and then stopped charging only to run off the battery while still plugged in. Not normal for any other device I've owned. I would prefer it to stay at 100% until I'm ready to unplug it. Maybe using the supplied charger will do this. I used a USB A to C cable plugged into USB wall port. I have replaced several outlets in my house to ones with built in 2.1A USB chargers.

I'm not understanding why anyone would not use the supplied charger and cable.

Why should it matter? wattage is wattage. Does the phone charge differently with the stock charger? Do you always carry it in your back pocket? Do you ever use a car charger?

Carry the phone in my back pocket? No, I don't but what does that have to do with the price of tea in China? I do not use a car charger either. As for wattage, I believe that the type C 3.1 chargers output at 100W and possibly 200W whereas the one you are using might deliver 18W. There might also be damage due to wiring with some of the 2.0 - 3.1 adapters but I'm still researching that.
So why wouldn't you use the type C charger? Besides, you can't plug it in backwards or upside down. And once you get a computer that supports type C the data transfer rates will be astonishing from what I've read.

Do you carry STOCK charger in your back pocket.
Point is, sometimes I need to charge it at work, or elsewhere as I may use it heavily. That's why I would use another charger. Point is, why does it stop charging on the charger and not draw from the charger once it's full. Like I said, mine charged fully then stopped using the charger drawing from the battery. Kind of pointless if I leave it on the charger to be full when I leave in the morning if it's not going to be full.
I'm glad its not just me who finds this a bit odd.
I used the same charger with my nexus 5x, galaxy s6 and nexus 4 and always found the phone at 100% in the morning.
The 6p obviously works differently.

I see what you mean. For a quick boost charge I can see you carrying a cord in your back pocket. I'm really trying to get a full 14-18 hours with this device no matter my usage. If I can't I really cannot justify this expense. I have 4 phones on my plan, a Samsung 5S, two iPhones 6s, and up until yesterday my N5. All other 3 got a full day plus even watching video and listening to music constantly. So no, I'm not carrying a charger, a cord or buying a car charger.
As for your problem of charging, have you tried the stock charger to see if you can get to 100%. I have already twice with no problem. Last night I wanted to unplug it once charged to see how much it drained overnight but I fell asleep at 93% and unplugged a few hours later. 6 hours off the charger it was still at 99% so I'm assuming it charged to 100 or close to it. Perhaps you can do a full charge overnight and then a spot charge during the day if you need. I'm thinking you might not.
I am also having this problem. I am using the included c to a cable to charge with. The phone stops charging around 95% and doesn't charge ever again until I unplug it and plug it back in.
These are the problems with this:
1. Cases where i do not have the included charger with me.
2. On long trips where my phone is plugged in all the time to prevent it from dying. (Streaming music, navigating, etc)
3. Sleep tracking
I'm using the Anker 5 port charging hub at 2A each port.
once your battery gets fully charged 100% - the charging stops to prevent your battery from overcharging. since your battery is not charging - your battery will drop down. once it gets down to 95% - charging resumes until it gets back to 100%.
in other words - that is normal.

Every other phone I have ever had did not do this and instead trickle charged at 100% and ran everything off of the charging port, never had a phone that constantly drops to 95% then back to 100%, that would be a roller coaster during car trips. The problem I'm experiencing is not that situation either; the phone will stop charging and never get charged again, so it could drop to 80% while connected to the charger. It knows it's connected to a charger, but doesn't draw current from it. Doesn't show the charging icon or charging AC, but the lock screen shows the percentage of battery.
I do have possibly some positive observations however. Last night I decided to try it without my USB 3.0 extension cable, and only the measly 1 foot c to a cable Google provided. Without the extension cable my phone charged as it should, went to 100% and stayed there with the charging symbol still on the battery icon. Upon removal of the charger, the battery stats showed only 3 seconds of use, whereas before it would just show everything since last 100% (which was sometimes 50 hours even though i charge my phone every night). I'd have to keep observing this to see if it was indeed the extension cable.
That's interesting wrt the extension cable. I have a extension as well. Will get rid and see what happens. I keep meaning to try stock charger and stock cable but can't be bothered.
It's not normal behaviour or else it'd happen on other phones. I've had nexus 4 iPhone 4s htc one m8 Samsung galaxy s6 iPhone 5s and nexus 5x all using the same charger / extension all have charged to 100% and stayed there.. Except the 6p.
It's not a massive deal, typically it'll loose 1 or 2 percent over night once it's been to 100.
Just an update, it was the extension cable. Phone charges to 100 at stays there until unplugged as is expected behavior. Just don't use USB extension cables to charge devices
