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....

I was asking the other way around.
To use Nexus 7 to charge my phones. But the previous user just answered, thanks James.
When traveling, I want to carry just one charger for all my devices.

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.

soo currently the Newtrent battery packs are on sale and i would like some opinions about the packs. :highfive:
Not needed for 95% of people who can find a power outlet of some kind once every 24 hours.
If you're going camping for a week I guess it could work. Or if you game on your phone 12 hours a day.
Not needed for me.

I have two battery packs. One slimline Anker battery that is great for emergencies. That one has a cord built in to charge. That one is like 3200mAh
I also have a new trent 10000mah one as well. That one travels with me. Has two usb ports to charge up my N4 and N7. Pretty fast too. However doesn't hold it's charge as well as the Anker IMO, but works.

If I'm going to rely on a battery pack, I'd rather get the biggest capacity of ~13000 mah.
I've had a New Trent 11,000mAh external battery pack for well over a year now and it's been pretty solid overall. My biggest complaint is that charging the battery pack itself is a little bit of a pain in the ass because it's really picky about the connection to the wall wart, you have to turn the piece that plugs into the battery pack until it connects just right to get a good charge. I assume this could just be a minor defect in my unit. I would say check out some of the other options out there as well, I picked up a 5,000mAh external battery for $20 on Amazon as a stocking stuffer for my wife this last year.

Recently,i have tried charging off my Nexus 4 using the ipad charger as the original charger was not readily available.
I have observed the phone charging time has decreased considerably.
Checking for the technical reasons,ipad Charger serves 2.1A at 5V vs 1.2A at 5V by default charger.
My question how does this impact my battery on Long run?

Fast-charging a battery negatively affects battery longevity somewhat. Ideally, if you want to preserve your battery, you'd charge it at the slowest rate possible (i.e., USB port at .5 A).
Given that the Nexus 4 has an improved battery that lasts 800 full cycles as opposed to the industry standard of 500 full cycles, I may not worry too much about it. It is more likely that you'll change your phone first.

Your battery isn't going to "die" per se. It just means that after 800 full charge cycles, the battery will hold less than the original capacity, typically about 80-90%, then 70%, and so on.
I think the higher voltage charger creates more heat which in turn will degrade batteries or electronics in general, making them not last as long. But who really cares anyway because a battery shouldn't be that hard to change out anyways.

I'm just wondering if using a different charger would affect the Z1's battery life?
I've seen the description on the original charger, and it's charge rate is 1.5mAh and with the phone's 3mAh battery almost 2 hours for it to charge. Now, my sister and dad have tablets and their chargers' charge rates are 2mAh.
Again the question is, would using these charges affect the life of the Z1's battery? Again, I'm very concerned because as you know, Z1's cannot be replaced conventionally.
Thanks for your feedbacks. Appreciate it.

Hi guys! You're totaly wrong. If you are use high-ampers chargers for your phones, you can destroy your battery or, at least, significantly reduce the battery life. I have some bad experience with motorola radio stations wich we use in some airport service groups. When we buy hi-ampers chargers for it we was happy by time of chargeing, but after half of year useing it we just throw out all accums, because it began to hold charge about hour or two only
After consulting with with motorolla support we have found that its strongly not reccomended to use charger with higher amperage then recomended by manufacturer.
As a result:
Positive - we have quick charging time
Negative - disastrous decline in the lifetime of the battery

Thank you for your insight.
I have several questions though:
1) how long have you been using this 2amp charger? Was it continuous usage?
2) do you have any idea, or any exact figure on what "too high" means in numbers? That way we can all benefit if Sony phones could handle the extra "uhmp". And anyone who has a Z1 who can attest to this?

2amp isn't problem.
I'm using that charger (from my N7) and only thing I changed is cable - I'm using magnetic-microusb cable and that's great combo.
I'm charging Z1 from the day 1 (I bought Z1 in October 2013) and my battery is still perfect.
25-30hours with.5.5-6.5 h of screen time.

The rated output of a charger is the maximum output, however it will only output what the phone takes in - in other words, if the phone only takes 1.5A, the charger will only output 1.5A even if it's capable of 2.1A. Using a higher ampere charger would only work if, say, the phone can take in 1.5A but the charger only outputs 1A, then using a 1.5A charger would boost charging times

Yeah, that's what I also believe. But hey, then why do most gadgets heat up a little bit more when using a stronger charger? I'm not doubting the principles that you mentioned, but I need something tangible to look at: like an article from Sony for Z1 itself.

Gadgets heat up more when using a stronger charger because of my second premise - that the phone is capable of taking in a higher amperage than the charger that it came with. I think such a scenario is more likely since manufacturers would find a balance between charging times and heat, since too much heat would permanently damage the phone's charging circuitry as well as shortening battery life, so they provide a charger that outputs a lower maximum than what the phone can take in.
I do not know of any documentation Sony might have on this, but this is more or less physics in action. I did find a couple of readings here and here, and the main snippets are as follows:

I just got myself a new V20 yesterday. I tried charging it with my own Quick Charge 3.0 wall charger but I'm not too sure about the charge time.
So I'm going to try again. But before I begin, I need some advice.
How do I check if it's really charging with Quick Charge 3.0? Also, the phone now is currently about 66%, how much more do I have to drain before I commence?

As much as you want. Thing to remember...QC is variable rate, the more charged you are the less fast it is. Also, official posted charge times from OEMs refer to a phone powered off typically.
Right. Powered off. Good point.
And I supposed using an app like "Ampere" is not going to work because of QC3.0's variable voltage and amps, am I correct?
Sent from my LG-H990 using Tapatalk
Okay. Just did a little test.
Started at 5pm with 25% battery left and using my own QC3 wall charger.
Ended at 5.50pm with 91%.
That's pretty fast! And the best part, the battery stays cool despite Quick Charge.
I'm going to try charging from 0% tonight.
Edit - Oh and my phone was turned off while charging.

Just an FYI, it's not good to drain your battery to zero. It'll shorten it's life. Keeping it between 40-80% is optimal from what I've read.
Sent from my SM-T810 using Tapatalk
Ampere app on Play Store, check it's charge current values specially when screen is off. I think it should be like between 2400 mA to 3200 mA. When screen is on , the charge current values decreases. Also with the app, you can compare the current values of QC 2.0 versus QC 3.0. Cable should't be faulty.

Ampere might not be the best way to measure current values because of the way Quick Charge 3.0 charges with variable voltage.
The few times I measured all fall below 1000mAh.

Hey fellas, not to take over the subject matter but feel like you all know batteries well. What if a 1am charger is used overnight for charging. Going with the idea that a slower charge charges the battery better and maintains a better charge all day, or is that not the case. Also is any harm done with charging with a slower charger. Thanks
I never use quick charge at work or at home, slow charging will prolong the battery life. I always start to charge at about 8-15% where possible, and disconnect the charger around 90-95%, this is the proper way to prolong litium battery.
The only time I use QC is when i'm traveling.

It is better to use a slower to prolong the longevity of the battery. You won't get more 'charge' from using a slower charge. I try to use slower chargers when I can. I usually use my Samsung 2A chargers and use my adaptive fast charging when I need quickness. The LG QC 3.0 does pretty well though. Battery doesn't get that hot but I'm quite sure it still isn't good for the longevity. Nonetheless, we have swappable batteries so I can use my AFC and LG QC 3 more often lime I do my note 4. My HTC m8 and moto x pure usually were used with 1A chargers most of the time unless I needed a super fast charge. Also, LG makes quality batteries. Probably why Samsung is switching to them until they figure out what the hell they did. Also, notice apple doesn't use quick charging technology. iPhone's battery tend to hold charges better until a out 18 Mo th period before user starts noticing appreciable decline. The peeps that put iPad chargers on iPhone's will see less longevity from their battery.
So I thought that QC3.0 was supposed to get you closer to 80% in 35 minutes, vs the 50-55 from qc2.0. So I also read that the factory charger that LG sent is a QC2.0 and not 3. So I bought a 3.0 brick and also a new usb c that is certified compliant with QC3.0. Still only got to about 40% in 30 minutes. Not sure what's going on with that. I understand longevity and all of that. However I got this phone because once my battery is shot I can just swap it. So I don't mind getting that faster time and buying a newer battery a bit early.
