[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

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.

can I use 2A charger?

Yes you can use a 2amp charger I was using my S4's and it charged fast

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.

thanks, I will try to see how much it will be faster or not

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.

Battery full charge takes 5 to 6 hours

Hi all
How much time does it take for you to fully charge your xperia zl from 0 to 100. Mine takes more than 5 hours. This is unusual. Dining send it for replacement.

Are you using the wall charger or just through USB on the computer?

I use the charger+cable which came with the phone, and it takes like 3-4 hours to charge it completely.

I use wall charger I even got a fast charger with 1500mA rating still it takes more than 5 hrs
Sent from my C6502 using Tapatalk

Are you using it while it is charging, or do you leave it with the screen off to charge?

I have left it without using still it takes 5 plus hours. Tried multiple such combinations

After market cable can cause this because it has low amp output, I also faced the same issue if I use 3rd party cable, using original or cable that rated atleast 1amp output will shorten charging time.

Might be value in testing charging while the phone's actually powered off... (might be some significant power drain from a running app...)

Hello everyone
I also noticed that my device takes a while to load
However I noticed my charger shows the model EP-880 1500mA
I believe that may be a firmware issue

I was using another cable that originally came on my Xperia Mini which are both different models (using was to be longer)
So I started to use the original (Cable Model EC801) and now loads faster
I noticed that the cable Xperia Mini has two boxes (which would be a resistor or something?) In the middle of the cable, and ZQ does not have any of them

What are the specifications of the official Xperia ZL charger as I bought my phone without the charger and I had to buy another Sony charger separately and I don't know if it is the official one or not, if any one can post a picture of the charger, that would be very helpful.

ZL charger has 1.5amp output, just search for any charger that has this output or more. You can charge with 1amp charger also but it will take a longer time and ur charger will become too hot once it charge in a longer period. It will shorthen ur charger lifespan.
Other than that, ur cable output capability also play important role, search for atleast 1amp output cable, more amp more good but a bit expensive. Just google the spec of the cable or ask the seller.

Guys I confirm that mine was also because of the cable. I took Samsung cable and put it in my charger head. Now the charging is ok

Wall Adapter [Q]

Could you guys recommend me a wall adapter?
I heard that i should get a 1500 mA one, but the best i found on amazon is Belkin Universal USB Wall Charger EU which is a 1000 mA ( i'm not allowed to post links yet, but if you search it it's impossible not to find it). I have to tell you that i can only buy it from the UK and that it needs to be a standard EU plug.

The one amazon.de sent me charges fine, the only issue is that it turns on my device if i try to charge it when it's off. The charger is a 5v 1A.
My iPhone 5S wall charger is also a 5v 1A but it "behaves better" i guess, because when my moto G is off wheni plug it to the iPhone 5S wall charger it doesn't turn on my phone automaticaly, it charges fine and the moto g only shows the battery image on screen.
Both charge ok (1A 5v), but if i want to charge my phone when it's off i guess some chargers won't be able to do that. Maybe it's an voltage accuracy.

I use adapter from my Nexus 7, otput is 5V 2A and no problems.

Any wallcharger will do as long it is 500-1500mA but i think anything over 1500mA can be used, but the device will limit it to 1500mA.
But i wouldn't recommend anything over 1500mA as it could damage the device.
The higher the mA is the faster it will charge.
Currently im using the Sony Ericsson Live Dock DK10 to charge my Moto G but im looking for a more powerful charger.
Press Thanks if i have Helped!

Additional amperage does not harm the device, only incorrect voltage will. The phone will only draw as much amperage as the charging chip allows.
Having said that, keep in mind that quick charging will wear out the battery faster than a slower charge.

I'm using a 750mA, 5V Blackberry charger for mine - from empty it takes about 2hrs 45mins to fully charge, so a higher amperage should be pretty fast. Doesn't boot the phone if the phone is off.

i bought this one

didn't receive it yet

In case anyone is wondering whether the old Apple wall charger is working or not (the one from circa 2007. I broke my other decent wall adapter...), it's working almost perfectly. It's correctly recognized as wall charger and ~1A is drawn from. That's quite surprising, It had always been wrongly detected by all the phones I tried to charge with it. The only drawback is that the device can't be charged when off, the device will simply boot as soon as it's plugged. This doesn't happen with proper wall chargers (at least on JB, I don't know if something changed with KK).
To know if a wall charger is detected as such, dial *#*#4636#*#* and see if it says "USB" instead of "CA" in the battery informations. Usually USB means lower current (~500mA) and kernel wakelocks (not always this one, it depends on how the charger is detected). That's not good.
You can also get the amount of current flowing though the battery using CurrentWidget (look for it on the Play Store) or reading the files in /sys/class/power_supply/battery/.

nothing happens if the moto g connect a charger that 2.0a galaxy s4

The Asian dual sim version comes with a charger with a hard wired cable, rather than a micro USB cable (and interestingly, its only got 2 wires connected from what I can tell). Its 500mA, and mine uses a UK plug. I've also tried it with a HTC charger (the moto charger has a VERY long, unwieldy cable) thats also 500mA and it works too. There's no real need for a higher amperage, and it does tend to charge pretty fast.

How many amps will the G4 draw when charging at 5V?

I know this phone is Quick Charge 2 capable, but does that apply only to high voltage charging, or also to standard 5V?
I ask because I bought a 3.1A charger, and though the phone was almost dead, it didn't charge any faster than the 1.8A charger that came with the phone. Is the charger defective, or will this phone just not draw 3.1A at 5V?

QC2.0 is 9V at 1.2-1.3A.
Normal 5V is at around 1.7-1.9A only.
It will not draw anything more than what's above. FWIW, IMO, QC2.0 doesn't make a huge difference

Thanks. So QC is only a protocol for changing voltages, it has nothing to do with negotiating or handling a higher current draw?

QC is a protocol for allowing a maximum possible current draw at a predefined voltage. Just because you have a higher possible current supply from a charger it doesn't mean that the G4 will draw more.
E.g. G4 can only draw 1.8A a 5V. If you use a 1A charger, it can only draw 1A but if you use a 2A charger it will only be able to draw 1.8A and not the full 2A.

This phone is **** at charging 1% every 3mins at best. I'm at 44% 23 degrees Celsius and it says 2hour 4min to 100%. Ampere shows its only drawing 480ma on a 2A charger. Three cables.. Note 4 cable, Stock cable and a high quality third-party cable all the same. The cables work fine as they charge to Note 4 quick and a Tab 3.
I give up. I even put this LG poss on ICE to 18 degrees Celsius but still same crap. Night charging for me then. Even Note 4 quick charger can't help it.
Nice phone for sure but I'm going back to Samsung next upgrade, sorry LG.

It does sound defective, unfortunately. Mine charges at up to 1%/minute, and that's without a QC 2.0 charger.

I use LG stock charger and a third party 2.1A charger to charge, Ampere shows that it has around 1000 mah. Apart from the charger, the charging cable quality do affect the result too. Try to swap cable and test again.
IMO﹐stock charger with 5V 1.8A can charge quite fast with 2+ hours to fully charged from 0 to 100%, no need to go for QC2.0.

I have found that my Original Samsung 2.1A charger sucks for the G4. Somehow it knows its a Samsung and doesnt want to provide anything over 1A. That charger charges at 2A my Galaxy S4. It takes like 3-4 hours to full charge from under 15%.
My LG G4 charges fkn fast with the original one and a Tronsmart QC charger. 1% every minute.
