Charger Concerns

I see that the wall charger for the Galaxy Nexus outputs 5V and 1A. Unfortunately, none of the extra chargers I'd like to use as additional chargers have this output. Some of them are 5.1V, and some of them all put out under 1A.
From what I understand, using a charger w/ a higher voltage could potentially damage the phone. I know that this unlikely considering it's only an extra .1V in my case, but I don't want to risk it.
As for the amps, I believe that using lower amps isn't dangerous, but may result in charging taking longer than normal.
Are these two assumptions correct? Also, does anyone know of any cheap chargers that put out 5V/1A? If you put in "phone charger" in Amazon, the second hit is a Samsung OEM charger that puts out 5V/0.7A, but I'd rather get one that is going to be an exact match.

700-800mah are fine and acceptable for charging. But if wanting to play games on a charger and still get some kind of charge, go with a 1000 mah charger. 1000 mah charger is also best to use while using mhl so you can hopefully not lose battery charge while streaming video over hdmi.

Speaking of the charger... anyone found a cheap charger adapter for the Nexus? I don't like the massive brick of a "international adapter" Handtec packaged with the phone >.>

I'm using a Griffin charger for the iPhone (1 amp)... it's very small and the plug blades fold up, making it very pocketable. Give the included iPhone cable to a friend.

Haha, it's a nice charger.
If you don't get that one, do get a charger that does at least 700mA... or ideally 1A. Some of the cheaper chargers don't put out a lot of power and it will take a long time to charge your phone.

edit: some people are reporting that the charger only charges at 0.5A instead of the full 1A on [some] android devices. if you have the charger, can you confirm your nexus charges at the full 1A watts

Same one.
Good question on whether it's putting out a full 1A. I guess what I do is check the charge times tomorrow with a few different 1A chargers to see if it measures up.

I use this for home:
http://www.amazon.com/Cellet-Charger-Retractable-Cable-myTouch/dp/B004XVM1T0
And this for the car:
http://www.amazon.com/Griffin-Powerjolt-Dual-Universal-Micro/dp/B0042B9U8Q
Both are dual-USB and put out 1amp. Charges my GNEX and iPhone 4 (work) at the same time without issues.

Just feel like to chime in here for another question.
I know typical USB port from a PC outputs 0.5A while the wall charger outputs 1A, so besides charging time, is there any particular advantages to use wall charger over USB from PC?
I've read somewhere else states that despite the longer charging time using a USB port from a PC, it provides more thorough charges hence is better for the battery than using a wall charger, is this true?
Thanks!

I've read that the wall charger drops the battery down to 90ish % after it hits 100% and just goes between the two levels until you unplug your charger
While a USB charge is slower and charges your device up to a "fuller" charge
...I may be unfathomably wrong though

man that little Apple charger is so damn cute ... lol , ill probably end up buying it once the 1A volt charge is confirmed

I'm not an expert on the subject but I was under the impression that cycles (charge + discharge) were a bigger factor on battery life than something like this. The longer a current is running through the battery (charge or discharge) is detrimental to it's life span.
Leaving a laptop plugged in all the time ruins its battery is my source on this one. I would say it's because it has a constant charge running through the battery.

500mA is the max before the PC will disable the port. So your actually get less current.
There are some ports, depending on the motherboard that have a option of outputting more power for charging devices, and also have the port powered when the computer is off. But a normal usb 2.0 port is limited to 500mA max per spec... so a normal usb 2.0 port charging a phone is drawing less then 500mA, or it would get and over current condition and disable the port.

I design electronics and work with USB and batteries often, so let me clear some stuff up in no particular order:
- PC ports are limited to 500mA so will only ever output a max of 500mA
- You can use a wall charger that outputs 1000mA but on most devices the data pins on the micro USB need to be shorted to tell the phone it can try to draw more than 500mA. This is true for HTC devices for example. That means if you get a cheap charger that doesn't short the data pins, when you plug your standard micro-usb cable into it, it will still only charge your phone at 500mA.
- The charging controller is actually in the phone. It decides based on temperature (there's a sensor in the battery), current, voltage across the battery (current charge) and characteristics of the type of battery to figure out how much current to allow into the battery. Although its true that a 500mA charger may have different affects than 1000mA chargers, there usually is very little perceivable difference. Which is (slightly) better really depends on the charging controller and how it decides when to stop charging.
- When the battery is full, the phone continues to 'trickle charge' for a period of time. This isn't a bad thing. Overcharging a Lithium battery can be extremely dangerous, so normal charging occurs at a high speed and then slows down at a safe limit below the 'true' 100%. After that the phone continues to trickle charge to top up the battery. This is the reason you read in phone manuals you should charge the phone for 8 hours or overnight for its first charge.
- When charging at 500mA, the battery does not get as hot. This usually means you get closer to the true 100% before 'trickle charging' starts. With a 1000mA charge the battery heats up a lot more so charging may switch to trickle much sooner. Here's an example with made up figures.
Lets say you charge your battery with a 500mA charger, and it takes 2 hours. When the phone shows 100% it may actually be at 99%, and trickle charging. Leaving it for another 30 mins may take it to its full capacity.
Now, lets say you charge your battery with a 1000mA charger, and it takes 1 hour. When the phone shows 100% it may actually be at 98%, and trickle charging - It stopped sooner because the battery was hotter. Leaving it for another 30 mins may take it to full capacity.
Conclusion.. the 500mA charger took 2.5 hours, while the 1000mA charger took 1.5 hours. However if you unplugged both when the phone showed 100%, the 500mA charged battery may last longer, and so you think the 500mA somehow resulted in a more thorough charge!
At the end of the day, it doesn't matter which you use. the absolute charge cycles is what counts. Charge to 100%, then dont charge till its 0 for best battery care. Constantly plugging into a charger or dock all day on and off is bad. But having said that, your phone is there to be used, so a sensible balance of the two is the best bet.

Thank you so much for the detailed response, kam187. Would you recommend avoiding using a 5.1V charger, considering the phone came with a 5V charger?
Sent from my Galaxy Nexus using Tapatalk

I wouldn't use it. The 0.1v probably won't make any difference, but it may not be regulated. Chargers with these odd values sometimes don't have any regulator inside them. That could damage your phone as the voltage could shoot up and down as the current draw changes.
Just search amazon/ebay for any MicroUSB charger, and pick one from a reputable manufacturer like Motorola, HTC, Samsung etc. Since all phones now use MicroUSB, there's loads of these chargers around from previous phone models etc.
Here's just one I saw on amazon.com:

It's safe, but it won't speed it up.

so 4 hours charge is normal? (With the stock charger)

I dunno, never timed it, but charging a LiPoly battery faster than that can shorten its life, and since its not removable, that would be a pain.

One additional thing. Learned that the hard way.
Bought a HTC car charger. HTC supplied cable to that HTC car charger. Original HTC car charger on this charger sucked... despite showing AC charging
So look first when you charge if it says USB charging or AC. And then check how long it does to charger. Change the cable to the original one supplied with the phone if it's more as on that original stock charger

Well charging doesn't have 100% efficiency so a 1a charger won't charge at 1a, so a higher charger means you should get to the 1a limit but it's not going to reduce charging times enough to notice.

A charger rated at output of 1A should be capable of outputting at 1A. Of course, it will draw a little more power from the input than it provides to the output.
When charging, during the first phase (constant current) the maximum current draw is typically around 1A, for up to about an hour, then it drops off quite quickly when it moves to the second phase of constant voltage.

how long does it take to charge the nexus 7 FHD?

mine seems to charge to slow, or maybe cuz im not using the stock cable and im using my usb ports on computer
but if i have stock charger on wall outlet, how long is the charge top up take from 10% to 100%, thanks

yea mine is charging slow through the computer but I dont know if its because of the nexus 4 usb cable im using.

Obviously charging through a 500mAh USB 2.0 port would be slower then through a 1.35A wall charger.

Yes you can use a 2amp charger I was using my S4's and it charged fast
Sent from my totally stock Nexus 7 FHD

Interesting, I've only charged mine twice since getting it last sunday, and I've not paid any attention as to how long it's actually taking, one was through a proper charger, and finally today plugged into my computer

The New N7 ships with a 1.3 amp charger, and it's definitely slower to charge than the old N7 (which shipped with a 2.1 amp supply).
But I have yet to determine if putting a higher current supply on the new N7 will result in more current being delivered than the stock charger.

It takes about 3 hours to charge from 0% to 100% with the charger it came with. Using a 2 amp charger doesn't decrease the time, as the device will charge at a maximum of about 1100-1200 mAh.

Android Tuner battery history.

Can anyone tell me what the power draw should be using the stock charger and cable?
Battery monitor is telling me that it is +237ma, it is taking 12 hours to charge. I have sent back to Asus via PC world (what possessed me to buy from there I dont know) and they have told me there is nothing wrong with the device. I have flashed the stock image and still getting notoriously slow charge times.

With the stock charger and cable, the battery should be charging with close to 1200mA; the charger draws 7.4W from the outlet (at 230V).
There is current limiting based on the voltage the tablet sees, a USB cable with thin wires can drastically limit the charge current.

Galaxy S4 takes 5-6 hours to charge. What's wrong with my phone?

I purchased a lightly used Galaxy S4 this week, and my phone seems to be working pretty well and my phone typically lasts me about 1 day with about 2-3 hours of screen time. The seller included the stock wall charger and battery with the phone, but for some reason, my phone charges really slow at night when I'm sleeping. It would take about 5 to 6 hours to reach full charge and this has been happening ever since i got the phone. I have read numerous reviews that state the average charging time is 2 hours, so I am assuming there is definitely something wrong with my used phone. What could be causing this problem?

Check the specs of the home charger. Since it's a used phone it's possible that the charger is not
the stock 2.0A which comes with new galaxy s4's but instead a 1.0A which is a common charger
for galaxy s2 and s3 phones.
Read the fine print on the wall charger to find out.

There are two kinds of cables, one of the cables will only charge, the stock cable which comes with
the phone will charge and transfer data between the computer and the phone.
But for charging purposes, both cables will charge the same speed when connected to the wall charger.
So you can charge with either cable with the same charging speed.
The main thing is the actual AC Wall Charger, to me it looks like the reason it takes you
5-6 hrs to charge is because the charger you use is 1.0A instead of 2.0A...
It should take 2-3 hours for full charge.
Good luck!

Make sure you don't have "Fast Charge" toggled in whatever ROM you're using. It noticeably increases power when connected to a computer or whatever DC source, but even when connected to AC power, Fast Charge will considerably lower the power output of the stock charger.

I'm running stock and didn't apply any roms. I hope it's just the charger, but is there anyway to test if it maybe a faulty usb port on the device without spending 20 dollars for a new charger to find out?

I can't say, but I will add that I've used numerous chargers and the absolute lowest I've seen was right around 420mA. That's obviously nothing more than my observation from using 8-10 different chargers, but still...

Try a different cable first. The stock cable should be the best but maybe u have a bad one. Its cheaper to replace than a charger.
Also try charging from a computer to see if ur phone takes more than 300ma. Try different chargers too. Most are 1000ma.
You should be able to narrow down the faulty component. If its not the charger or the cable, then it might be the battery or lastly the phone itself.
Walk into any cell phone store if u need to test with spare cables or chargers or even batteries. There should be some cool guys there

Chargers range from 1A-2A output. The cable will also affect the charge speed. I tried replacing the cable on my Samsung charger with a cheapo $1 one, and it wouldn't charge for crap. Swapped it out for a higher quality one, and it worked great.

I might keep my note 3 charger for this. Usually charge quickly.

Tmo variant ships with a 1.8A as well. Not sure what you've got that came with a 1.5A. Charges in about an hour and a half with my longer cable I've got at home and 2A samsung charger I have at home. I don't use the LG one it came with because it's too tall. It's about double the depth of the charger that I currently use and I've got it crammed behind a file cabinet. Also the cable coming off the end of the charger instead of the side is a poor design considering that the charger is already so deep to start with. The charger it came with definitely wouldn't fit back there.
