[Q] Does USB charging harm the battery ?

I mean compare to wall AC charger, that is.
question.................................

no
charging a battery is always very "difficult" for the battery. if you charge not so fast, the battery wont get hot anymore and it's better for battery life. but it takes 2h 30 minutes and with a/c you need 1h

nope..not at all..usb charging gives very less amount of energy compared to AC charging..thats why it takes more time to charge and it is completely safe

True. I prefer charging my phone by USB. This way my phone never gets hot. If your don't have time then use AC charging.

but whatever happens just avoid car charging!! its can do more damage than we can imagine

Becoz car battery does not give stable electricity and output with variance electricity that may damage your battery.

I've got no idea if its safe for the battery, I prefer AC, I never charge my arc over the computer. What about the difference between USB and AC is that AC gives you 850mA an the computer USB(2.0) only 500mA!

Car chargers are safe as long as they are decently made (Fully Regulated). A good regulated Car charger is just as safe as any other charger.
Lithium Batteries are pretty hardy as far as charging goes. (just dont over charge or fully discharge)
as far as USB is concerned, some USB2 ports will supply up to 900ma,
I charge my phone on my Tablet charger all the time (2000ma or 2Amp) simply because it is FAST. sure the phone gets warm but the phone/charger will regulate the charge as it needs to.
it is also good to note that the quality of the charger is very important.
cheep charger = more likely to damage battery as well as cause funny issues with the phone when plugged in.
Pvy.

Exactly. Your battery will prevent it from getting over charged. It's safe.
Personally, I use Nokia chargers as they deliver a higher output.
Nokia AC-10N gives an output of 1,200mA. [Home - AC wall charger with a long cable]
Nokia DC-20 gives an output of 1,000mA. [Car charger with dual USB ports; both ports output 1A each].
Been using both for a long time now without any issues. Didn't go for the SE chargers because of the lower output, which takes longer to charge the phone.
And to the OP, USB charging is safe.

hox & fast chargers

Is it safe to use a 2.1a 5v usb charger with the hox?
Will it speed the charging? (Stock charger takes 4 hours to charge!!)

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.

As Ben
said should be safe but won't speed up

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.

[q] long battery charging

Hi
Is it normal that my xperia arc s takes over 4 to 5 hours to complete a full charge?
I mean, I`ve read here that some people said that they have a full charge in around 2 and a half hours.
Does the fact that my arc is international and im on America? Here the voltage is around 110-120 V
Or is the charger itself? It saids something like ECO FRIENDLY, and if i charge throught my computer i dont see any difference in the charging time... and its suppose to take longer this way.
Could be my charger? Need to buy a new one? And it is safe to buy a generic one?
Thanks

It's not normal for me, as it takes up to an hour and a half to fully charge. However it may the regional differences in voltage that may be the cause. The voltage we have in Astralia is double yours, at 240 V.
As for the generic charger, it'll be fine

Thanks
But the voltage zone only affects the charger or the phone and battery too?
I mean, sony made them different for each region or just the charger?

Check electric current on your charger also.
My charger has output 850mA and I also have fake charger with output 500mA. Charging using fake one makes my phone touchscreen crazy and charging takes ages.
USB also has current 500mA.

lol, my charger has 1500mA output . I have 220 V in my house, and the phone charges in ~1 hr 45 min

Check the o/p value of charger mine is 5.0vdc takes 2 hours for full charge.. Input value differs from country to country.. That's 100v to 240v ac.. Here in India 230v

Looking for good charger

Hello,
The charger i've received with the phone seems to be cheap and not good enough, someone can recommend a good one?
Thanks

I'm using a blackberry original charger with 5v and 800mAh and this gives me ~3 hours of screen on during in ~ 40hours of usage.
In this time I make phone calls for ~1h ,I keep data on only in needed.screen brightness is set to auto75℅.I don't play games too often.WiFi stays on for about 20h.
I observed that using a lower amperage for charging,battery drains slower.original charger has 1.2Ah and charge the battery in about 2 h.this 800mAh blackberry charger does it in ~3.5-4h.
Try to charge your phone from a USB 2.0 port.it will take longer,but you'll notice some increase in battery lasting.

I use about 4 different chargers and they all do the same job for me. I generally look for USB chargers that can do more than 1Amp and that seems to work fine for my Optimus G.

i tried a cheap 2amp Charger (Russian copy or something of a Samsung Charger) and it worked oki for like 2weeks, but what i noticed was that it didn't charged my phone faster then the original LG charger (I am running CM11/Android 4.4.2)

Can someone suggest a decent car charger?
I have tried several types but they barely keeps the phone from discharging when screen and GPS are active.

Use a charger which has 4.8-5.0V output with 1-1.2A or 1000-1200mA rating. My phone charges up in about 2.5hours and lasts more than a day considering I use little amount of wifi, more of texting and less of phone calls.

Up

I was using amb charger of 1 ah and it was good . Yesterday i bought hama twin port charger with original Nokia cable . Thats also a good combo . What matters most is keep phone temperature to minimum during charge . I ve noticed one battery temprature reaches 35 degree celsius or + , it would not charge and just drain .

im using this samsung note 2 charger.
5V 2A
its so fast

sometimes I plug in and I see slow charging. When I check battery status it's written Charging (USB) there. I unplug then plug in again and : charging (AC). What's the reason for that?
I'm using stock ROM and stock charger.

Does G pro port differ from G? I once charged a g pro with my charger. Can it be the reason?

great post, i want to buy a new one.

I use a anker 4 port charger with 2.4a. Device is fully charged in 1,5h!

1.5h with lg g3 charger and cable also.
~2h with original charger but with g3 cable.

Compatible charger for xperia t2 ultra

Hello, and thank you for using XDA Assist!
As this phone has a microUSB v2.0 connector, any standard charger will work. It's not recommended by the company (standard line), but all MicroUSB chargers (that I've come across) are compatible.
Hard to know which amps to select (USB standard is 5 volts), so I would match what the genuine was, which was probably 5V, 2A. If you had quick charging before, your replacement charger will probably only have standard charging.
At any rate, I am connecting this thread to the forum your device experts are found:
> Sony Xperia T2 Ultra > Xperia T2 Ultra Accessories
They should be able to shed some light on what the genuine charger specs are.
Hope this helps, and good luck!

The original charger which comes in the box is just 850 mA and to say it straight it sucks .. dont get charger below 1000 mA coz the stock 850 mA charger take more than 4.5 hours to full charge
so as @OfficerJimLahey said i recommend a 2.0 A charger .

I oppose it
I've used 5v 2.0A output charger
And it does charge to 100 percent faster than 1.0A
But your battery drains faster, and also while charging your mobile sometimes reaches very high temperature which i think would damage the phone on continuous usage.
It's my personal experience..
Soo..i just recommend any charger with 5v and 1.0 to 1.5 Amps output
2.0 Ampere is just too high.

Here is the info you need:
Re: Sony Xperia T2 Ultra Dual compatible charger Current Output 2.1A
What's important is the voltage. The charger must be 5.0V.
The amperage is how much power the charger can deliver.
