GPS & bluetooth + charger =no charge

While traveling I was using the gps (coPilot) with my bluetooth on, (just for calls) and was getting low on battery!
So... Naturally I plugged in the charger! Guess what! Battery drained nonetheless!
Has anyone else seen this? I have the screen brightness to the lowest setting... But to no avail!
I apologize if it's been covered before, but just looking to see if anyone else had this issue and any suggestions on making that battery not run down while plugged in!
Thanks everyone! Oh, and yes I have a second battery for these occasions!

Yes. covered before and many people see this. May be worth tying a 1amp or higher charger.

Also, if the phone gets too hot, it will stop charging.

I have the same thing... Its just don't charge however it maintain the battery at whatever level it was.. This is simply fixed by getting a higher amp charger

Thanks everyone will get a higher amp charger...

Are any of you guys with problems using the Samsung Cardock , or
are those chargers "random" chargers of other phones ?

my official samsung charger that came with it has decided to pack in after a month of use, it no longer charges at the rate it used to of about 24% an hour and im lucky to get about 5% an hour now. I've tried my old hd2 charger (same 5v 1a output) and it charges without any issues
samung make crap chargers

That's what I think the issue is, I'm using a generic charger and it's not pushing enough juice!
Gonna pick up another charger soon and report back.

I got a 1A car charger with my mount which works ok (cheapo chinese says 1A). I think any car charger with a USB slot which says 'Ipad' would work better, IIRC the ipad needs ~2.2A so it would have plenty of juice.

I've got various car chargers, one at 850mA, one at 1A and one at 2.1A. None of them charge the Note while using sat nav (Copilot) even using night mode (dark backgrounds to maps) and dimming the backlight in between junctions. I've tried the USB lead that came with the Note and a lead from another phone. No improvement.
The phone shows Charging AC because I have the central pins shorted on the chargers, but even that is not enough. I'm thinking the only solution is to buy a proper Samsung charger, which might have some other trick up its sleeve for getting the Note to draw sufficient current.

I have just switched from using co pilot to another satnav app and the phone now charges faster. I knew co pilot was juice hungry. ...

Using Nexus 7 charger to charge mobile phones?

Hi,
Nexus 7 charger ouputs 2A.
Is it safe and ok to use it to charge Galaxy Nexus, Nexus S, and HTC Desire?
I am thinking more in the long run, if it does not brake the phones.
Thanks

It should not hurt anything.My daughter charges her Droid 4 with my charger every day.

It'll charge it really slow since phone chargers are 1A. Everyone will have their opinion on this but my opinion is I wouldn't use a phone charger on the N7....it could over heat due to it charging slow. But I'm sure you'll hear others saying a slow charge is better so....

Yup, it's fine, because a standard charger is, or used to be, 500 mAh, at 5 volts.
Some chargers are more mAh, like 700, and some are even 1 A.
If a charger is 2A, and your phone only draws 500 mAh, that is perfectly fine, because it's only drawing a quarter of what the charger can produce. In this case, the charger probably won't even get warm.

Neither my Sensation nor my wife's Sensation XL has died yet from using the Nexus charger
What mvmacd says is correct - just because the charger can supply 2A, it is the device that decides how much current it draws from the charger.

I actually find the charger that came with my razr does the job fine and its rated at 850ma. Other lower power chargers i have are slow though.
I doubt a slow charge would lead to overheating or else connecting to a pc would cause this too.
I think for chargers its a case of trying them to see how well they work.

Science proves other than your opinion. A too-low or too high max voltage or amperage charger can and will lead to overheating and severe reduction on battery life and can destroy the adapter as well.

Care to explain why Google says you can charge your device with a 500 mAh charger [standard USB port]? ["with the screen off"]
Won't it severely reduce battery life and burn out the motherboard of the USB? Oh, really? Google just forgot about that part when they were writing the instruction manual?

Modern devices and chargers shouldn't have this problem because of built-in regulators. A smartphone won't try to draw more than it can handle and chargers won't try to supply more than they can handle (unless they're very cheap).

I have been N7 charger on phone with no problem so far. I wonder about the statement about the phone not drawing more than it needs though. I replaced the battery in my TB after 9 months due to low life and swelling. I'm pretty sure the swelling came from leaving the phone on a car charger all day, even after the battery was full. If my phone had the ability to stop taking the charge it didn't need, this wouldn't happen...

My opinion still stands....I don't trust using anything other than the charger that came with the device. 6th post down makes perfect sense to me.

Your battery was likely defective. My phone literally stays on the charger all day when I'm not out.

If the phones also charge at 2A then you should be fine. If the phones charge at lower amps (say 1A or 1.5A) then I wouldn't recommend using it everyday as it may reduce the battery efficiency. If it's an emergency go ahead and use it.

There's no harm in using a higher current charger with a lower current phone because the charger is not what's actually charging the battery, it's the phone, and the phone will limit the charging current. You can confirm this with a multimeter. The charger can't force the phone to draw more current than it was designed for. This would be different if you were charging the battery directly with a dedicated charger because then the charger itself is directly controlling the charging current.

[Q] Is it safe to charge with Nexus 7 charger?

I have a Nexus 7 factory-included charger and I was wondering if I could safely charge my Nexus 4 with it. Reading from the specs printed on the chargers, the N7 charger outputs 2.0A at 5.0V, while the N4 charger outputs 1.2A at 5.0V. If it's safe, would it affect the N4's battery longevity in the long term? Considering it would be charged with a higher current.

Yes the battery life will reduce more quickly if you use more current to frequently charge it.
Sent from my Nexus 4

It won't be charged with a higher current. The charging circuit will only draw what it needs regardless of what the supply can output.

Yes, you can. The charge controller is in the phone. This is perfectly acceptable and will not harm your device in the long run.
I've been using my Nexus 10 charger to charge my Nexus 4, which has the same output as the charger you just described.

Higher amperage will generate more heat, which in turn can damage circuitry and the battery. At the end of the day, it's your call.

I don't suggest you charge it with the nexus 7 charger all the time use it only when you really need to get a quick charge.

Yes, higher amperage will generate more heat, but the battery management system (BMS) is sized for the battery. The BMS will not allow more current into the battery than it can handle. This is independent of how much current the power supply can provide.

Using the Nexus 7 charger (or any other higher amperage charger) WILL NOT

Damage your battery
Cause your phone to draw unsafe amount of amperage
Cause your phone to get hotter than normal
Make your battery charge faster
This is 2012, not 1831. We have industry standards and the microUSB standard was designed with the idea in mind that users may have both chargers with varying amperage outputs and devices with varying amperage inputs. People much smarter than us designed the standard to be compatible, a novel idea right?

It does work fine like the iPhone/iPad charger dilemma. The BMS protects the battery from any damage, so there is no need to worry about abnormal decrease in battery life.

I wish I could find my post I did about this in another thread.
Yes it is perfectly safe, if not safer, to use a higher amp charger.
It is not safer to use a higher VOLTAGE charger.
Why? Ohms law.
The phone has 2 resistance settings triggered by the data lines of the port. If they are open (computer USB port) it sets itself to 10 ohms. Thus drawing 0.5A (500mA) @ 5V.
If the data lines are closed (wall or car charger) the phone sets itself to 5 ohms. Thus drawing 1A @ 5V.
Amperage is determined by the resistance of the phone.
The rating of the chargers are the MAX amps you can draw from them before they melt down or break. NOT what they push out to your phone. Amps are pulled/drawn out. Voltage is pushed out.
Don't believe me? Get a 5 Ohm resistor. Attach it in series with a multimeter on amps to the outputs of each charger. Then check the Amps of both chargers. It will be nearly equal (about 1A). NOT 1.2A and 2A!
I should make a video demonstration about this, because I see this question a lot!

Sorry, but there are a number of folks here who do not understand basic electricity, yet feel qualified to post advice about it.
A typical electrical outlet in your home is capable of delivering 15 to 20 amps. If you plug a device into one that can only handle one amp, does it explode or is it damaged in any way?
Electrical circuits present a "load" to the supply they are connected to. This load determines how much current it will draw.
This is middle school electric shop folks.

Umm, Not really sure if this helps..
But I've been charging my N4 from my N7 charger since I got it. The N4 charger/cable are still in the box.
I have not seen any side effects as of yet, but no clue if there could be months from now...
Would this be the same "questioning" between charging the phone from the provided outlet adapter vs a computer USB port?

A USB port is only capable of supplying 500mA, and that is what the n4 will charge at when plugged into one. This is actually handled by the phone as it knows it is a computer based on terminations on pins 2 and 3 (data signal). Power is delivered via pins 1 and 4.

Charge using different charger

Hey i just want to know it is safe to charge this phone using 5 V 0.7 A?
Because i see in the normal charger, the output rating is 5 V 1,2A.
I am currently using my previous samsung charger (5 V 0.7 A) to charge my nexus 4. It is safe or not to do this?
I dont mind for if the charger take more time to get my battery full anyway.
Thank you very much

A piece of electronic equipment only uses what it needs as far as electrical current is concerned. I am using a 2.5 Amp cigarette lighter charger with my Nexus 4. I could have used a 5V 100 Amp charger if I wanted, although it would have been tough trying to fit that giant connector into the micro usb port.

^ +1 You should have no problem using any charger that adheres to the USB spec and provides 5V reliably.

Even that is unlikely because the phone regulates how many amps to draw. The current allowed is regulated based on multiple factors including the battery temperature and the charge present in the battery.

Well the second scenario was if said bits failed

amps / volts
Think of volts as pressure, and amps as volume of flow.
Think of a conductor as the empty space of a pipe, the insulation as the pipe wall.
Higher volts needs stronger pipe (conductor insulation). The limited insulation in most modern electronics will burst if to much pressure (volts) is applied, causing a short and a fried device.
Higher amps requires a larger pipe (conductor) and will most always be limited by the size of the pipe, or the amount of volume consumed downstream.
If a charger puts out 100 amps and only .75 can fit through the pipe under a giving pressure (5 volts), then only .75 amps will be able to come out of the charger, without damaging anything.

No fast charge ?

Disappointed that the xperia z5 charger only has an output of 1500mA. I've read on forums where some xperia z5 owners were given the 1800mA (I think) out of the box. My previous Samsung Galaxy S4 had an output of 2100mA so I'm wondering if I used that charger can the xperia z5 take advantage of the extra mA?

Nope I had to use another charger to get the fast charge up and running

Still with any fast charger i get 1600ma to the z5, while my s5 juiced 1800ma

Ampere from play store.

I use that also I think to make a claim like that you need to take all scenario like the phone will drop rate the more it's charged. Mine currently says 1560mah but max is 1610mah that's starting at 77% it would slow down again at 80% I also think that software tests will never be 100% accurate just like all these software benchmark tests that are available.
I think what I'm trying to say without offending anyone is the stock sony charger would be able to achieve 1800ma
Also things to take into consideration is things like if the phone is on and what apps are also using battery

Can you tell me what the specified output is on your charger? Mine has 1500mA so I doubt you can pull 1800 if it's not designed to do it. My question is that can the Z5 take advantage of a 2000mA charger from Samsung or any other manufacturer.

Ah I apologise I don't actually have a new charger only an older charger I'll have a look at the rating later. It would however accept the Samsung charger I'll have a dig around for the ratings in the data sheets

I'm going to use my old samsung galaxy s4 charger in that case. I have no idea why Sony is supplying a mediocre 1.5A charger. Even the 1.8A is still too slow for the current size of batteries in smartphones

I didn't even get a charger with mine as O2 are too cheap to provide one.
I'm using Samsung S6 fast charger and LG G4 normal charger.
Fast charging works very well.

I actually use a Blackberry 2.0 Amp charger, and it definitely charges all my phones (Z5,Z3,Z1) faster than the stock Sony charger. My Sony charger says 1.5 Amp and it's ok, just not as quick.
The Blackberry charger has the added advantage of having a nice long lead, as opposed to the short lead which Sony provides. It is a dedicated charger only though, so you can't use it for file transfers.

Its kind of weird that other users are reaching 2.0A of juice from their chargers, while some are not.
Unfortunately for me, QC does not work. I recently bought a Tronsmart TS-QC1W usb wall charger. it is Qualcomm QC 2.0 certified, and it did not make any difference because the Max Ampere I was only getting is 1540 amp. I also happen to have a power watt meter where I can measure the watts this charger is pulling in from the wall, and it is just getting ~8 watts (meaning 5V x 1.5A = ~8 watts). I only thing I like and is useful with my tronsmart is, I love the long thick usb cable that came with it.
Just incase a dev or anyone is working or curious in this issue, I am using:
Sony Xperia Z5 dual (E6683)
firmware 32.0.A.6.66 (stock, havent updated to the most recent)
Sony UCH20 stock charger
Tronsmart TS-QC1W Qualcomm QC 2.0 certified
Charging Time from 0%-100% = 2rs 15mins
next thing I would try and do is, update my firmware, and hoping that would enable QC for my Z5. Or if that fails, I hope Sony is currently aware of this and that its upcoming marshmallow update will enable QC 2.0.
(BTW, I can confirm that ALL Z5 Premium can reach and pass 2 AMP of juice from a fast charger. I dont have any data from Z5 compact though).

The Z3 Compact series has gone through these same discoveries. Sony (for some reason) doesn't FULLY support QC 2.0 charging speeds. You'll only see about 1.5 amps when charging with the phone on, and maybe a bump to 1.8 when the phone is powered off (not just screen off). Because of this, 2 amp tablet chargers are effectively just as capable as the expensive quick chargers.

To all of you who are using charger other than stock for some extra amps are ruining the battery ? life of your device.

Because phone can't draw more current than set by manufacturer, doesn't matter whatever the charger you use. But using a higher rating charger can cause more heating, which actually degrade the battery life as it accelerate the reaction inside the battery because of rise in temperature.

There is still no proof that it will cause heating and degrade the battery life though. The phone will only ask for so much draw that it can handle from the charger I'm all good for people correcting something however you need to provide proper proof to show it is a fact

It is well known and has been proven many times that the faster you charge a battery the hotter it gets and less charge cycles it lasts.
Sometimes it might be necessary to do a quick charge, but i don't think it is a good idea to QC your batteries every day.
