Yes, cases marketed for the N7100/N7105 will fit the SGH-I317 along with other GALAXY Note II models, as the hardware layout is identical. That being said, I'd recommend staying away from cheaper TPU cases or if you're buying in person, ask to try the case on first -- the reason I say this is because some cases aren't cut very well, I've seen a few where the cutouts for the camera and the charging port were too small for example.

As a pretty unknowledgeable semi-active member of XDA who reads every single root/return to factory related post before rooting his phone, who tries to help other members a little bit when I can, who learns some code when he has time, I also mess and play with my phone a lot. Occasionally, I do stuffs with my phone that I don't really understand because of the confidence that I (probably) won't brick my phone and as long as I can boot to the boot loader then I am fine.

But... I still feel that doing stuffs without knowing what is the really idiotic stuffs to avoid is kinda dumb.

So my question is, what kind of actions from the phone/adb would lead to a permanent dysfunction of a Nexus 4?

[Nexus 10 Q&A, Help & Troubleshooting] bits8mybytes:
Hey this is a great tablet, but I noticed a bug and was curious if anyone else had this issue? When my screen is on max brightness and charging I noticed the battery will slowly lose charge. This becomes the most obvious if watching netflix or gaming. I hope someone can point me in the right direction of fixing this, unless of course it is a physical limitation of the device.

Edit: I have this problem when charging to a wall outlet, and when connected by usb. I am using the stock samsung charger. I understand the limitations of usb charging through a computer I am more suprised by the AC adapter connected to a home outlet not supplying enough current.

[Nexus 10 Q&A, Help & Troubleshooting] SlowCobra96:
Search the web I believe I read that this unfortunately is a problem with the device. Maybe it was attack of the show. I know I heard/read it somewhere.
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
The Nexus 10 charges pretty slowly, so if it's using more power than it's getting, it's going to go down (though slower than if you weren't plugged in). Computers generally can't supply that much current, and most USB chargers are 1A. The stock charger is 2A, so use that when possible for faster charging.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
The thing that you plug into a AC outlet is a power supply not a charger. The charger is in the N10. I've measured it with a current clamp meter and the N10 isn't even asking for half of the 2A that the power supply can deliver.
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
Clamp meters generally aren't that accurate for such low amperage (obviously depends on the meter). In any case, the 2A supply can give enough for the battery to charge and for the device to be used concurrently. It may draw an amp just for charging, but that leaves another amp for the device to be used while maintaining peak charging speed.

This is all speculative, as I'm not 100% that the charging and device power usage is parallel.
[Nexus 10 Q&A, Help & Troubleshooting] e.mote:
Here's an easier way to determine N10 charging power that anyone can do. Get a Kill-A-Watt for $18 from Walmart, and plug the AC adapter into that. This doesn't directly tell you how much current the N10 pulls, but does allow you to infer charging current from the wattage pulled from the wall. You can then compare it with iPad 4 charging graph (in wattage) to determine N10 charging power as a percentage of iPad.

Below we see iPad 4 pulling a constant 13.6W for ~4hr before tapering off. iPad 4 uses the new 12W (2.4A) charger w/ Lightning connector. Assuming 80% conversion efficiency, it's about 10W (2A) going to iPad. iPad 4 averages 5-6hr for a full charge.

http://www.anandtech.com/show/6472/ipad-4-late-2012-review/7

iPad 4: Battery size = 42.5Whr, charge current = 2A, charge time = 6hr. N10 has 33.3Whr battery, and also averages 6hr. Assuming similar charging power curve, N10 would need to pull 2A * (33.3/42.5) = ~1.6A to achieve same charging time. So a measurement of less than 1A charging current is likely inaccurate, unless measurement was taken at the (tapered) tail end of the charging process.

Note 1: Per Anandtech, iPad also suffers from net-loss charging under heavy use, so the slow-charging issue stems from USB charging's limitation for high-capacity devices.

Note 2: Charging power may also be limited for thermal reasons. N10 already have a thermal throttling problem as it is, and faster charging would make this worse.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
It's high quality amp meter using its 4000mA range. It's draw less than 1A total, so if the battery is at 80%, it's not charging it as fast as it can. It runs off the battery and the charger replaces the usage. If demand is high, more comes out of the battery than the charger is putting in, not because it can't get it from the PS either.

It could charge twice as fast but the N10's internal charger is slow.
[Nexus 10 Q&A, Help & Troubleshooting] bits8mybytes:
Arg consensus says it's related to an internal charger limitation, no hope of a software fix? Well thanks for the responses.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
The AC current drawn by the charger doesn't infer the DC current. I have "AA" charger that charges at 7.5A(not a typo) and it doesn't draw 7.5A AC. I have a car battery charges at 2, 4, 10, 40A and car start at 100A and of course, a normal wall socket is limited to 20A max.

I'll have to check that again at a lower battery level to make it wasn't in the constant voltage part of the charging process.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
I measured over 1800mA current draw with the screen on full and 2400mA with full brightness playing asphalt 7

I measured my tablet going from empty to full in 5.5 hours which makes current from the PSU around 1600mA

Looks to be that USB2 can't keep up with the power this tablet can consume when working flat out. Maybe they should have gone with USB3 as that can supply up to 5A
[Nexus 10 Q&A, Help & Troubleshooting] e.mote:
>The AC current drawn by the charger doesn't infer the DC current.

AC current isn't considered; I'm looking only at the wattage and assuming 80% conversion efficiency. We know that USB = 5V, so from there we can infer DC amperage. It doesn't make sense to use a 2+A adapter at less than 50% of its rated output, especially when the charging time is already a long ~6hr. Using iPad as a baseline provides another point of reference, which says that 6hr charging time is probably considered "normal" for this high-capacity category.

>Maybe they should have gone with USB3 as that can supply up to 5A

As said, higher thermal would be a problem for faster charging. The underlying issue is N10's high-res screen, which only the Exy 5 can drive at the time of design, and why the latter was selected (Duarte dude said as much in N10 promo clip). The screen+SoC combo requires more power than can be compensated for, in both its thermal envelope and its charging capacity.

OK what others are saying is that the issue is from the limitations of USB in general unable to exceed 1.8 amps. I guess we have to wait until a decent pogo charger comes out which is rumored to have 2amps. There are 3rd party ones being sold for around 24 bucks on ebay.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
I calculated these numbers from usage data.

battery capacity / hours of use

screen on full brightness

9Ah / 5 hours = 1.8A

Playing Asphalt

9Ah / 3h 40 min = 2.4A

These numbers actually close to double with the screen on around 20% brightness

There are alternatives. Microsoft managed just fine with a 24w Charger. I suspect it runs at 12V 2A, but can't find any specs

http://www.anandtech.com/show/6385/microsoft-surface-review/9

ASUS also do something similar, using 15 Volts to lower the current and reduce energy lost in heat.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
How can you get 2.4A from a 2.0Ah PS?

I retested making sure my battery was low enough, at 80% with it OFF, I got around 800ma. It isn't my meter but there is one posible flaw in my setup though. I'm using a USB extension cord and it may be causing a voltage drop because of the added lenght and skewing the reading.
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
The voltage drop should be negligible for a USB cable, and any minor deviations should be corrected via regulator in the Nexus 10.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
Then my max 800ma charging rate is correct and skally's calculations are incorrect??
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
Alright, I just spliced a cable, and measured the current draw via regulated power supply (constant voltage). It seems to draw around 747 milliamps no matter the load on the tablet. My battery is 60% right now, so it probably varies with charge, but I don't think it goes as high as 2 amps.
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
Ah, I'm not alone!:) That's why the POGO charger "might" not be any better.

If you want play more, start full charged while still on AC. Run a bit and put it to sleep. Most often(at least for me), when wakened, it will show not charging by the device but it really still is at a reduced rate. You can easily see this using the Battery Monitor widget because when you unplug it the discharge rate will increase or on your current meter, of course.
[Nexus 10 Q&A, Help & Troubleshooting] bits8mybytes:
My personal experience has shown that certain cheaper usb extension cables can significantly affect power. To the point that a web Cam can not turn on. Just so you know.

Does anyone know for certain it is the internal regulator of the Nexus that is unable to hit this fabled 2.4 amp charge on max brightness, or is it in fact related to the USB specs and we shall get the correct amperes from this magnetic dock charging cable that others have been peddling in the accessories thread.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
You misunderstand. 2.4A is how much current the N10 I was consuming from the battery without the PSU connected. This thread is about battery life.

Sorry, but what meter are you using? By your numbers, you are saying it takes 11+ hours to charge your Nexus? Mine is empty to full within 6 hours. The calculations are simple.

Battery capacity in Amp hours / Charging current in Amps = Time to charge in hours. The 800mA you suggest therefore becomes:

9Ah / 0.8A = 11.25h

We've already covered this on other threads, but here it is again.

The Nexus 10 draws around 1.6 Amps from the PSU. This can easily be inferred from the time it takes to charge from empty

9Ah / 1.6A = 6 hours

The POGO connector is expected to increase the charging speed by 25%

1.6A * 1.25 = 2.0A

BTW, if you are not sure about how much Volt drop is in your cable, here's a quick rule of thumb: If the cable is less than One hundred feet long, your Volt drop is likely to be less than One Volt;)
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
Maybe for a period of time, but charging isn't ever linear. I directly measured the current draw at 60%, and it was drawing only 750ma.

I just measured again (my tablet battery is at 46%), and it was draing 430ma.
[Nexus 10 Q&A, Help & Troubleshooting] bits8mybytes:
Thanks for your wise words. I will wait for the POGO.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
I don't understand what that means? the output from a Switch Mode PSU is as linear as they come. Do you mean it is not constant? I am aware that a LiPo charge cycle is a multi stage process.

So which is the more likely?

1. Your multimeter is giving you erroneous values,

2. Google have lied about the battery capacity.

3. 2+2 no longer equals 4

For a 9Ah battery to charge in 6 hours, then it would have to average 1.6 Amps. If it averaged less, it would simply take longer to charge. I don't see how this value is not set in stone.
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
I meant the current draw isn't linear, and is higher in some stages of charging. The value I'm giving is an instantaneous value. That's why your simple calculations aren't giving reasonable results (although it might be correct in some other charging phase). I'm not actually using a multimeter, but a heavily regulated power supply, with a readout for current. It's definitely not wrong - I use it for much more sensitive system development.

When my battery is close to dead, I'll start charging it and keep track of the current every hour or so, so we can see more of the temporal characteristics.
[Nexus 10 Q&A, Help & Troubleshooting] skally:
My calculations are perfectly reasonable. It's your current measurements that don't add up. Current draw for LiPo charging IS Linear. That's how it works.

The temporal characteristics of a LiPo charge cycle are well documented. There are 2 stages.

Stage one is Constant Current. This stage is complete when the Voltage in the battery pack exceeds 4 Volts. This is usually at 80% battery capacity.

Stage two is Constant Voltage. This stage then gradually lowers the current until the pack voltage gets almost to 4.2 Volts. The battery is then considered fully charged.

I have no idea why you are seeing lower values, but the simple fact is that, If it spends any significant amount of time at a lower current, It will take longer to charge
[Nexus 10 Q&A, Help & Troubleshooting] wptski:
I'm using an Extech 98042 current clamp meter which lists for $380. There are two us measuring lower than what you are calculating from battery size and time.

I'm not really sure what/why but my battery was at 78%, OFF and about one hour later it was at 95% which calculates to 1530ma. It would seem that there has to be a current amplifier circuit in the internal charger to boost the current to the battery.

---------- Post added at 05:39 PM ---------- Previous post was at 05:36 PM ----------

The Battery Monitor widget has shown fully charged at over 4.3V.
[Nexus 10 Q&A, Help & Troubleshooting] rp181:
Keep in mind that .8 amps at 5v is around 1 amp at 4 volts. And I don't think the cells will be above 4.2 volts. I measured again at 33%, still drawing 750ma
[Nexus 10 Q&A, Help & Troubleshooting] skally:
I can see there are two people getting similar results, I cannot explain why you both get these values using different equipment. But you can also see the maths is correct.

There must be a logical reason. Maybe Google invented a way of harnessing Zero Point Energy;)

4.2 Volts is a safe voltage, and while they can go higher, sending them too high WILL cause them to get hot, and eventually explode. The 4.3V could simply be a rounding error in the Widget. Similarly, it could be that 4.3 is safe for newer batteries
