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

I've been doing fine with just plugging it into my computer like I always do with every other phone.

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:

2A vs. 1A charger

In the meantime I got inspired by some threads in which people claimed that 2A (amp) charger will make it faster to charge up my note then original 1A charger. I bought original Samsung 2A charger for Samsung galaxy tab and tried that out and I must say that during the first week or two the charging time decreased from around 2.5 - 3 hours into something around 1h 40-50 min.
Later on everything returned to standard 3 hours though, charging with 2A charger is almost identical to 1A charger so from my experience there is no added value with this approach (unless ICS will make a change, or some custom rom).
For anyone interested I enclosed picture where in the top row you may see charging with 1A charger after 1h50min, 2h40min (both just random pics), then when this app (https://market.android.com/details?id=net.whph.android.battery) said it is 100% and the last picture is when galaxy note (Android) system said it is 100% (green battery icon). In the bottom row there is the same scenario with 2A charger. I am on the stock rom 2.6.35.7-N7000XXKKA.

Im not sure but I think you need a kernel that allows more than 1A charging for the 2A charger to work.

I guess so, what makes me slightly uncertain is that initially, charging time was around 2 hours ...

This is an interesting thread. I'd like to get more information about 2A chargers and whether they really make a difference.
Also I heard that when plugged to a TV (using the MHL cable) the phone may actually consume the battery more, even when plugged to the charger simultaneously. therefore if 2A chargers charge faster, it may also solve this problem.

I actually have both, micro USB to USB and micro USB to MHL cables. Wasn't able to test them for a longer time as they sometimes work and sometimes don't, especially mhl cable shows videos for like 30 seconds and then there is a lost signal message on my TV, then it wakes up, then it is gone again ... I could fiddle wit it, but will rather wait for ICS upgrade and then will return to it again.

I did it, and while not with 2 notes side by side, you can have a look at the pictures at the 1st post, the time and charging rate shows its pretty same on the stock rom whether you use 1A or 2A charger. (Although it was very different first one or two weeks, after that battery get used to 2A charger and charging is as slow as with 1A ...)

SGN stock batt with ipad charger?
Hi, I see some of you are using 2A/ipad charger to charge you SGN. My question is, will there be any side effects on that could harm the stock batt in short or long run?
FYI, atm, I have an ipad charger for home and car and i intend to just use the same charger to charge all devices including my SGN. Im not looking for a fast charging option, but just a hassle free and conveniences.
I appreciate if you could give suggestion on a dual port charger (for home and car) where I can charge my devices simultaneously at one time.

No harm as long as the volatage output from your charger is 5v. This is what pushes the current to ur device. Higher it goes more it pushes.
However the current that the charger provides decides how fast it can charge. This will also depend on the device. If the device is manufactured to charge at 1 amp and u use a 2 amp charger then it will only use 1amp. If however u use a 750mah charger it can only use 750mah and charge slowly.

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 to get more speed charging?

hi guys,
i have two chargers,
1. output 9.0V 1.67A or 5.0V 2.0A
2. output 5.2V 2.4A
and a usb-c cable, in the cable box i find that this cable is supporting for fast charging and support to 2.4A but when i tried it with the two chargers, and test it using 'ampere' app i got max to 1010mA with both chargers adapter ! even with this value i feel it charging my mobile quickly, and in the bottom of the lock screen i see 'charging rapidly' but i want more and why the phone is not charged depending on the values in the chargers (1.67A - 2.0A - 2.4A) and cable (2.4A)

The P2XL charger is 9V, 2A or 5V, 3A. Your amperage values are too low, which may explain why you're not charging as quickly as you should be. The solution: get a charger that equals or exceeds the stock charger ratings.

You realize slow charging is better for the long-term life of the battery, right?

Considering we often get new phones every 2-3 years, you won't see much of a degradation from rapid/fast charging.
Rather, you'll see a degradation from charging from <15% to 100% (which people do often). That will be a more significant reason someones battery will lose much off its lifespan.
I wish Android would have a built in limiter. I'm sure in the next few years, both iOS and Android will.

There's nothing I can help you guys with. All I can tell you is what ratings your charger should have, based upon the information printed on the pair of chargers I received with my device when I purchased it directly from Google. If you have a genuine Google charger and the P2XL is still not charging fast, contact Google.

I thought that charging capped out at roughly 1000 mA when the screen is on to protect the battery from overheating/putting too much strain on it. Which could lead to degradation of the battery. That would explain why you only see 1010 mA on Ampere - because the screen is on. I don't think Ampere measures while the screen is off, so it is difficult to say what value it would be giving you.
That is my experience even using the stock charger that came with the phone.

There is one other thing that you must also have. The Pixel does NOT support Qualcomm Fast Charging. It uses Power Delivery, not Quickcharge Technology. So if you have a charger that is labeled QuickCharge or a Moto Turbo Charger you will NOT get fast charging from these units. It has to be a Power Delivery charger with a USB C port and the cable must be USB-IF certified. If you don't have all of that then you don't get a fast charge.

That makes sense then, it seems like everything gets more complicated every year.

I just purchased one of these from Amazon. Note that it supports Power Delivery 3.0. This unit quick charges my phone. The Moto Charger I have for my old Moto G5+ which is a Qualcomm charger will charge the phone but only at slow speeds.

what do you think ?

If it is really the OEM parts that will work. The pictures look like mine, but ya know eBay....

The original charger can charge faster than the 45W charger with the right cable?

I have information regarding the Note 10+'s 45W charging ability. I just completed my own charging speed comparison. I depleted two Note 10+'s and am charging them from 0 with the phones powered off. One is on the 45W charger and the cable it comes with. The other is on the original Note 10+ charger, BUT is using an aftermarket USB 3.1 Gen 2 C to C cable. The results are VERY surprising!
At around 7 minutes, the 45W charger jumped out ahead at about 23% while the original charger was around 15%. Somewhere between that 7 minute timeframe and 15 minutes though, the original charger caught up. At 15 minutes both phones were at 36%.
Here's where it gets interesting though. At 30 minutes, the original charger actually pulled ahead of the 45W charger! The 45W was at 65%, while the original charger was at 69%.
At 45 minutes, the 45W charger closed the gap ever so slightly, with it being at 83% while the original charger was at 86%.
At 60 minutes, the gap closed a bit more. The 45W charger turned in a charging percentage of 95% , while the original charger had a percentage of 96%
At 67 minutes, the original charger reached 100%, while the 45W charger was a little behind at 97%. The 45W charger would then finally reach 100% 2 minutes later ( a total of 69 minutes).
In summary, I found that with a USB 3.1 Gen 2 cable, the original Note 10+ charger is capable of the same charging speeds (actually slightly faster) as the 45W charger.

Cool test, you have a link to the specific cable you used??

Sounds more like a faulty battery for me

Interesting! Would you have a link to the type of cable?

Have you tried this same test using that cable with the 45w charger?

And could you repeat the test but swap the carger for the device (the one with orig charger gets 45w), just to make sure it isn't a phone "problem"

That's actually what I intend to do when I finish depleting the battery. I'm hypothesizing that the charge time will likely not be any different than with the cable the 45W comes with, as I'm guessing that cable is likely a USB 3.1 gen 2 cable. I'm guessing the cable that comes with the original charger is probably a gen 1 cable (just a theory).

I just completed it with the other cable in the 45W charger, and the results were almost the same (it reached 100% at 64 minutes) as they were with the cable that comes with it (pictures attached). Looks like the charger that comes with the Note 10+ is capable of more than we gave it credit for. We just have to make sure we're using a USB 3.1 Gen 2 cable with it.

I wonder why there's so much variation in people's charging results.
For example, with the video put out by Flossy Carter, he got 50mins from 0% to 100% with the 45w charger and a little over an hour with the 25w charger.
He charged 2 Note10+ phones at the same time, with the above chargers.

Edit:
Possibly stupid question, but you do have fast wired charging enabled, right?

It's not a stupid question lol. But yes, I have it enabled. Most of the other 45W tests I've seen have had results comparable to my 45W test. There seems to be a pronounced slow down towards the end. I don't know why Floss' test came out the way it did, but I can't replicate that on my two devices, and I haven't seen 50 minutes elsewhere either.

I didn't see any significant improvement with the gen 2 cable . it's taking same charging time as stock cable which came with the box.

The generation version only increase the bandwidth capability of the cable and should not have anything to do with charging.
If I'm not wrong, there should be something with the stock 45W cable to enable faster charge since it must goes beyond official USB-C specs.

The other thing to take in consideration with newly discovery made here is that the official battery capacity can be between 4170 and 4300 mAh.

The cable also has to be 5A and yours might not be. And use the cable that came with each charger (or 5A).
It's harder to find longer cables that meet all the specs but I bought several of these and they've been terrific...

Are you doing this with the the device off? Try leaving the devices on and see what happens. I know between 1-80% it goes a lot faster with the 45W charger over the 25W charger. The ET I don't bother following them because it's an estimate not a constant.

Flossy results are about the same as mine. Right under an hour from 0-100% and roughly 50 mins from like 10-15% to full. I am happy with that. Using a 10 ft cable as well not the factory Samsung charger

Man your chargers are both charging at 25W, 45W charging should last from 0% to 100% about 60 minutes, many finish in 58/59 minutes
