Hi guys!
I have recently bought a Nexus7 tablet which has a 5V/2A charger .
Can i charge the i9305 with the Nexus charger (5V/2A) or it will cause problems..?
Thanks in advance!

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

I'm pretty sure that you are saying the opposite way.
You can use more Amp but not more voltage.
More Amp - charges quickly.
More voltage - could blow your device.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..
The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

Careful. HTC does something funky with the wiring in their chargers and phones such that, when using a non HTC charger, the phone will only charge at 0.5 amp, vs 1 amp with an HTC charger. Net result is that your phone will take twice as long to charge with a non HTC charger. There are several threads on this subject, and I've observed it first hand on my One. The non HTC charger shouldn't hurt your phone though, only your patience...

I've never had an issue.. have had HTC for years now and have gone thru several chargers bought from walgreens and they all seem to work fine. I usually charge overnight anyway so I never time the charge lengths. Ymmv I guess?

I usually charge overnight as well. But I travel a lot, and when I do the GPS - a battery burner - gets a lot of use. What got me started exploring this, was when I saw my HTC ONE battery going in the wrong direction (slowly) while charging in the car while using the GPS. This led me to learning more than I ever wanted to know about HTC chargers and their funky wiring ... Apparently you can get around this by shorting two wires in the USB cable, but I have no intention of trying that!

I don't think the problem is at HTC but the charger you might have. I have successfully charge @ ~800mA (1000mA = 1 Amp)with different chargers ( Asus charger, Samsung charger and a newer palm charger). My new blackberry charger can charge @ ~600mA.
If I use my older palm charger, my Nokia charger, my old blackberry or a dollar store charger, it will only charge @ ~3xxmA.
If you read the spec carefully, you will see most newer *smartphone* charger max @ 1A, and older charger max @ 500mA. (or my BB charger max @ 800mA. )
So it's OK to use non HTC charger, just be sure to read the spec and find one charger =>1A.
Hope this help.
I'm on the lookout for a car charger someone can confirm will charge the One at full 1A speeds. I don't mean one where it claims to on amazon's site, but that you've actually witnessed it. Thanks for any help!

That is correct, usb specification is 5v, with 500mA (0.5A) maximum, hence the modified cable you refer to. The simplest way if you don't wish to modify cables is to buy HTC car charger

You can find HTC chargers on amazon that will give you the full 1 amp. Look for older phone models like treo pro or mytouch 4g and they'll be cheaper but work fine.

What happens if I charge the phone with a 2am charger? Does it damage my battery? Will it charge faster?

The charger *should* only provide 2A if the device (phone) request it.
Just thought I would chime in on some observations here. Long story short, when I bought my HTC One, I left the charger in the box and continued to use my multi-port USB charger with 3x1A ports and 1x2.1A port.
When connected to the 1A port, I found it quite strange that my phone was taking 4 hours or longer to fully charge. Also observed the same thing when connected to the 2.1A port. I was thinking that something was up with my phone somehow limiting the maximum charge current.
Anyway, I read a suggestion to use SystemPanel Lite to check for USB or AC power connected and sure enough it was reporting USB power. I remember the case with my Xperia X10 where you have to short out the two middle (data) pins on the cable or in the charger so that the phone detects that it is being connected to an actual charger. I tested it with my old Xperia charger, another generic USB charger, and the HTC charger and managed to get SystemPanel Lite to report it as AC connected.
But here is the interesting part. I have a car charger rated for 1A. Initially it never worked with the Xperia X10 until I opened it up and shorted out the two data pins. It has worked ever since. However, when I connect this to my HTC One, it still reports it as USB connected.
This has got me thinking that there maybe something more than just shorting out the two data pins for the HTC One to detect that an actual charger is connected. Just some food for thought.
Don't tell me HTC pulled an Apple and we have to buy only HTC chargers to get full speed charging? Does anyone have a confirmed non-HTC car charger that reports "AC" charging in SystemPanel Lite?

As per my post, I tested a generic USB 1A charger (it's at home, but it was one that was supplied with a Netcomm MyZone) and with my stock Sony Ericsson USB 700mA charger, both of which reported as AC connected. There has to be another way that these can be detected as chargers other than a simple short of the data pins.
Tested not to work so far has been an iPhone charger, Amacrox AX025-TACH1, Philips Power Bug, and two generic USB car chargers both with the data pins open then shorted.
Non HTC charger plugged into wall reports ac power. Proof

Good point. My apologies. The work "car" managed to be skipped as I read it.
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.
Sent from my One using xda premium
Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.
OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.
Is it safe to use wall adapter with more current than the standard 5VDC/0.7A rating for the i9000?
I have in mind 5VDC/1A or even 5VDC/2A. I have seen that several high current product vendors/suppliers do say they are compatible
As I undersatand, the technology of the batteries has the intelegence to request the current from the wall charger, therfore if more is desired than more will be supplied...
If there are any technical or experienced person than please help us understand.
Thanks'
Hi,
I use a 1A charger occasionally without any side effects, but I think as a replacement charger, it might shorten the life of your battery.
Mine is about 4 years old and still holds a full days charge.

Since I assume that the phone Battery has a charger circuit that regulates the current needed then having a high current reserve on the AC charger should not be an issue. The AC charger should even run cooler.

I've googled it and I'm getting very mixed opinions. Most say 2.1 of course is faster for charging. I am led to believe that because even the box to there car chargers say the same.
I would like to disagree but need help understanding why. Maybe I'm wrong and I have a faulty charger.
My charger has two ports. One is 1amp and the other is 2.1amp. My 1amp side seems to actually charge my phone faster than the 2.1amp side. Also with 2.1amp while in listening to music through Bluetooth using GPS and navigation all at the same time, it tells me my phone is dying faster than it's able to charge. With the 1amp side I'm able to hold a steady charge sometimes going up at least 2 percent during a 30 minute drive.
What's your opinions? This isn't the iPhone or Samsung threads so I'm sure we have some of the smartest guys/girls here on xda

It should be a no brainer that a 2 amp charger will charge your phone faster as opposed to a 1 amp simply because one has more output than the other. But I believe that because of the smaller battery the phones have, they need a smaller amp per second of charge. If not then it may destabilize your battery.
Thats just my two cents though. Dont quote me

HTC put a limit on how fast the phone can charge. The chipset supports rapid charging but at what cost (of the battery)? So to be safe HTC disabled that feature of the chipset. So even if you plugged it into a 4 amp USB connector, you are not going charge any faster than say 1 amp. Don't know what the specifications are on the optimal amperage...

Using a higher amp charger cannot damage the battery. The phone will only pull as many amps from the charger as it needs (probably 1.5 amps max).

Htc one battery originally is charged by 5V and 1A charger; Can 5v. and 1.3 A damage the phone?
One thing that nobody here has mentioned is the possibility that your charger might have been wired wrong and the side that charges faster is actually the 2.1mah connection instead of 1mah.
With all of the chargers from everywhere in the world that we get them from and they are supplied from, anything can happen that We don't expect.
Maybe you might want to get it tested with an OHM Meter to verify which connector is the Higher and which is the Lower.

The only thing that is different (as far as the phone is concerned) is whether it sees an AC style charger or DC style. No matter what, the phone will only pull what the charging circuit "says" to pull.

For some chargers, sometimes the 2 Amp port appears to be using the Apple protocol for USB power, so that port will only provide 0.5 Amps to most other devices. And when the1 Amp port somewhat over delivers, and can source 2 Amps if nothing else is connected and 1.5 Amps if the 2 Amp port is sourcing 0.5 Amps for a non-Apple device. Thus some chargers can support one high power non-Apple device (in the 1 Amp port) and one lower power device (in the 2 Amp port). FYI I use this charger bought on Amazon---Avantek. Worked really well, versatile and low profile.
