Hello i have been a very long time user of xda on all my android phones, in the past i have had this odd problem with my galaxy s2 it would do the mysterious "charging but not charging problem" basically i would leave the phone in charge at like 45% and come back an hour later only to find out the logo says its charging but it actually dropped to 24% which was strange at the end after months of changing the cables it ended up happening only "some times" later on i figured lets just change that usb power adapter and what do you know problem solved. But here is my new problem i just recently got an xperia z1 which i have a lot of usb cables for i started using the original cable and it charged as normal, then i was using my cheap cables and i noticed instead of the problem the galaxy gave me this one gave me a new problem where it would be at 61% when i leave it and 20 minutes later i come and its at 62% i put the original cable back and it worked like normal again so i guessed this is a similar problem like the galaxy except with the cable instead. Now 2 months later i am still using the original cable and i have this different problem it would go from 50% to 80% in 40 minutes and then be stuck like that for an hour an then move along like normal. I dont know what the problem is now because this is original cable and original power adapter. Any ideas?
I know that Xperia S had that, some kind of protection for overcharging.
It would stay at 88% most of the time, because first time it charge to 100 and then stop to charge and let battery drain some power. So maybe z1 have some similar stuff, but I didn't recognize that on mine. For me he stop around 96% mostly.

Use only the original Sony cable.
I had problems also.

You may have a bad reception and live in a hot place.
If your reception is bad then the phone draws tons of power. Quick fix: flight mode.
If your device is really hot when charging then the charging current is limited in order not to damage the phone. Try charging it in a cool place.
If this won't help either then buy a charger with 2A=2000mah output current.
Would always recommend using better cables to charge... Original Sony cable does +1500 ma charge and cheap cables does +300
That's your 20 minutes per % lol

I don't think that using genuine cable does any difference in Sony devices like it does in Samsung. Actually just using shorter, but thicker cable than genuine would improve charging speed.
i use a monitoring app
Battery Monitor Widget/Current Widget
Both can measure how much of +ma are being injected into the system
I've been examining these results for years with Android on HD2,EVO3D,SGS3,Z1
Cables make a difference whether they are
+300 (cheap cables)
+600 (car charger direct)
+300 to 1000 (car charger usb with 2amp)
+800 (original HTC cable)
+800 (orginal Western D cable for SATA ext disk)
+100 (cheap pink market side cable)
this greatly affects charging speed, and im 100% certain of this
your milage might vary depending on the cables you use, and the socket
i've just recently discovered a friends (Xiaomi cable) which does +1300 and it charges a hell of a fast
this also depends on whether you are using wall socket, powerbank, USB laptop, USB desktop but usually the bottleneck is on the cable
I'd like to let you know that the Z1 also limits the current based on the device temperature, just like it limits the cpu and GPU frequencies. If you don't belive me then open up logcat and get the device to warm up. You'll see the current limit going up. I think that it limits up to 500mAh current although it might not be the maximum cap. The best measurement of the current would be on a single hi amp charger in cold environment so the phone would be constantly cooled down.
Yes all devices also checks temperature and also, how many % remaining
Nearer to 100%, charging rates usually slow down

I don't think that ALL devices check the temperature and adjust it's processor speed and charging current. I really doubt it as the heat became a major issue somewhere around S800 chipset. There was no temperature control in xperia play at all.. If I were to speak about Sony then I guess that they implemented this somewhere around xperia s or later on the most powerful chipsets. I might be wrong, although I don't think I am.
I really doubt that the current changes depending on the current charge percentage, may I ask you for some kind of a proof? Regarding the charge and clocks I can give be you the proof without any issue, logcat proof, that's legit, but I've never seen any logcat about the charge percentage except for changing the image in the statusbar.
Can I discover what eating battety of my 2 week old Sony Xperia Z1 ?
Try some battery stats app from Google play.

Your phone is awake a lot of the time when the screen is off. Use an app like Better Battery Stats to find out what's causing the wakelocks. You can use Greenify to prevent apps from running in the background.
I also had problems with non Sony cable. Pluged in, handy is loading. 1 minute later it dont load. Best use original sony cable. With this i dont have problems.
Hi everybody, I have a question. Can I use 2000mA charger for my Xperia V or it will damage hardware? Because my stock charger is 1500mA
Thanks
Yep. Doesnt charge faster, tho. ^^
The only term you should pay attention is the Voltage,should be 5V.
The max input speed depend on the power management chip on your phone.
This is my understanding.

They (Sony) may tell you that you can't use other chargers, only Sony chargers, and that other types may damage your device. Knowing for what you can get sued in the USA I probably would say similar.
Any electric appliance will only take the amperage it can handle as long as the voltage is right.
My experience is that my Xperia V charges a little bit faster on 2A (2000mA) compared to 1,5A from the charger that Sony included.
I have never measured the max output of the Sony charger, but I find it rather small and light for a 1,5 model and it doesn't even heat up a lot so I doubt that it can deliver a steady 1,5A over an entire charge.
There is something you might pay attention to, certain chargers have a circuit that tries to recognise the device that is connected.
These circuits are not very intelligent, mostly it recognises if it is an apple or not.
The apples will get more A....
Simply using a "charge only" USB cable often helps to get the high A available for other devices.
This is often seen on external batteries, I'm not sure about aftermarket chargers, nor if Samsung chargers recognise Samsung phones.

It's been a month I'm using 2A Samsung Charger without any problem,just sometimes touch screen goes crazy when I'm using phone with connected charger
The buggy screen when charging problem I have it on my Archos g9 too.
Very frustrating as it happens all the time, not just sometimes.
I have never had this on my V though.
I think it happens because of leaking current on the Archos, as it has terrible build quality.
The V is a tank, and very well built imo, and shouldn't suffer from this.
Maybe your charger or cable has a problem?
I find it a little bit worrying because there are a lot of elements in there that would not appreciate the full 5v running through them.

Hi I have a xperia arc s charger that has been going strong for a number of years. Model ep 800 with a Sony ec801 data cable (xperia z).
Output is 5v and 850 ma. I usually charge at night so the extra time won't matter to me I've got the original charger in the work bag in case I need it.
The old charger won't damage my new nexus 6 will it?

It's no problem. I regularly use an old Samsung Note 2 charger on my N6.
Cool now just wondering whether to use ambient display or not, some say it's a battery hog some say it's fine. Oh well trial and error here we come.
Which charger to use? (no quickcharge)
I bought a Samsung charger for my upcoming Nexus 6, i don't want to use the quick charger that comes with the phone. I am starting to suspect that this one is also a quick charger, can anyone look at the attached pictures and tell me? Also if it isn't a quick charger i would like to use it for the long run so my second question is would my battery be affected because of what says on the back of the box that i highlighted? In the highlight are also the specs of the charger, can someone clear this up for me?
EDIT: I cannot post pictures on the forum just yet, so here are the specs
10W Samsung travel adapter, Input 100-240VAC 50-60Hz, Output 5.0VDC 2A
Use only with compatible Samsung devices

I want to use the phone for a couple of years and don't want to shorten the battery life and also have the risk of inflating battery and everything that comes with it. What kind of charger should i buy to charge it in some "normal" time? The salesman in Samsung store told me this one charges Note 4, Galaxy S5 - which is why i bought it - the S5 doesn't have the quickcharge tech so i instantly thought it was an ordinary charger. On the other hand, my Galaxy Nexus official charger is rated for 1.0 A which surely isn't strong enough to charge the 6 properly so i am confused with what kind of a charger and with what ratings should i get? Thank you in advance.

2amps isn't going to shorten the life below 2 years. Higher amps only shorten life if they are above battery tolerances, which 2 amps is not.
Anyway, you'll want a 1 or 1.2 amp charger for slow charging

Can i use this charger safely with the Nexus 6? After some researching this one is actually quickcharge 1.0 by the specs so i it should not be so "harsh" with the temperature on the phone.

Yes.
If I were you, I would use the charger that comes with the Nexus 6. Which is tested by Motorola to work properly. I've had my Nexus 6 since December 2014 and no problems. I charge through my laptop will at work though.

He wants slow charging. So charging through laptop / pc will be fine.
Charge cspacity of usb ports is 500 mA (900 mA for USB 3.0), that's good for slow charging.
Also 1-dollar charger from eBay will be fine.

Nope. So the only thing that will change is his phone will take longer to charge.
That said for me, turbo charge stopped working and I'm very annoyed.
Google have first sent me a new charger which still hasn't arrived. Though I think the issue is the phone. But I wanted to avoid a refurb as long as possible. Can't live without turbo charge now.
I have this charger, http://www.walmart.com/ip/Belkin-F8J031TT04-BLK-Micro-Wall-car-Chrg-Kit-2.1a-10w-W-4ft/40457559, but i got just the charger for $20. It most definitely doesnt turbo charge, it takes atleast 2 hours, so id say its a "normal" charge for this phone and i think its better than the turbo charger, because it doesnt get hot and its still decently fast

The turbo output is only supplied on turbo enabled devices. So there is something wrong with switching to turbo modes 9 V and/or 12 V
I am curious what is the cause of this issue.
Did you try an 'charge app' like Ultra Fast Charger.?

There are some apps in the play store claiming to boost the battery charge.
When wireless charging is also slow, than it could be indeed the battery.
Maybe a complete discharging ?
BTW
Turbo mode is only active when the battery is less than 75% charged.

You should use a 5 Volt 2 Amp charger, those chargers are the one's that most phones use. Most new phones are using Qualcomm's Quick Charge 2.0, which you should use but if you are not comftorable then the 5 Volt 2 Amp will work good.
Errr, QuickCharge will in fact degrade a battery faster, it's still used because most phones only have a 2 year lifespan.
A non QuickCharger will also make it run less hot while charging and also be less likely to cause cell expansion. Not sure why there's so many people denying this.
EDIT:
Including some sources:
http://www.sciencedaily.com/releases/2015/04/150414094117.htm
Please don't tell him that it won't degrade his battery when it definitely will. It's basic chemistry.
To OP:
Any regular non Quick USB charger of reputable make will do fine. I use an older HTC charger. Don't get a super cheap offbrand one as it probably has fluctuating voltage which will also damage your battery.

Actually you've misread (or not read fully). No one disputes the science. That article isn't accurate. All it says is "too quickly" and if you read what I have said, is that the turbo charger is within acceptable tolerances. I.E. It is not "too quickly"

I think you're not understanding the basic chemistry. More heat = more degradation of the Li-ion battery, regardless of tolerances. A lower power charge will always degrade the battery slower. This isn't about tolerances.
Hey Peeps
Anyone else getting slow charging on SM-T810?
Using the bundled charger, I am getting average of only 680mA .... Definitely nothing over 950mA and that is even when screen is off...
Using the same charger and cable on my sony xperia Z3 easily achieve 1400mA ...
Same sort of numbers with other chargers etc... So pretty sure it is device not charger...

I just tested and am getting around 1500 mA. That is with my nexus 6 charger.
Bundled charger gives me around 1460 mA.
Are you certain it`s not the app that is wrong as the S2 is new and the app might not have been updated yet, Try the Samsung charging app below, you have to keep pressing the refresh button on the free version.

The charging rate can be anything from 300mAh to the maximum the power adapter can output, the tablet will determine the amount of power it will accept, and will jump from fast to slow charge depending on how much more power is needed until it reach 100%.
Thanks guys - obviously does not seen to be wide issue.
I tried the Samsung app above ... Sort of showed similar values ....
I did a charge from 69% to full and it took about 1.5 hours... So would be maybe 5 hours to charge fully?? Unless the device does much quicker charging at very low battery??
I will do a full discharge down to say 5% and then charge from there and see how I go.
Thanks again

Normally it will trickle charge slow once it reach approximate 80%, and is normally fast if the unit is almost power empty.
It's annoying. I've tried both ipad chargers and a 2.4A charger, but it will go to slow charging mode with anything else than the bundled charger.

Yeah i have found exactly the same!! Must be some sort of Samsung handshake protocol...
There is another thread on this that I have mentions about this, just use a good quality charger, or just go for a Qualcomm QC 2.0 charger from any known brand like htc, aukey, xpower, lots to name, just searh Qualcomm site for a full list.
It won't used the QC2.0, but all should work just like the OEM Samsung one
the ipad charger should be pretty high quality though, so I don't get why it's being so picky.

If you also followed the tab S thread, it's also been mentioned, Samsung tabs S are also picky, and yes all apple stuff don't work.
Should I rephrase it and say some good quality charger will work, even branded ones like sony may not even work, but my intital testing, most QC 2.0 charger will work.
The issue is that I'm trying to find one charger that will charge both my tab s2 and my iphone 6+ quickly. Any idea how qc chargers fare with iphones? The bundled tab s2 charger only gave my iphone 0.4A (it charges the tablet at 1.5A)
I have both sony and asus chargers with included cables work perfectly with iphones and sony xperia z3 and nexus 7... Hopeless with S2.... But s2 charger works fine with them..

Odd, my old Nexus 7 2012 charger fast-charges my S2 710 without any issue at all. I had it spare as the N7 died on me (the S2 is its replacement) and was initially wondering myself as I had a few supposedly 2A chargers at home which only slow-charged the S2 (or indeed under Android 5.0.2 said it wasn't charging at all, even though it evidently was, but 5.1.1 has fixed that).
That said this is a charger without fixed cable (but with a decent USB cable) and I know from Raspberry Pi experience that the cable is almost as important as the charger for getting decent charging (ie enough current) to the device on the far end.
I would make sure the USB cable is a decent one intended for charging.
Proper charging USB cables have the shield connected at both ends for use as ground which is why they are notably thicker.

I agree, a good quality cable is required, as well as the charger itself, I'm using a magnetic cable and a reversible micro USB cable with a OEM Samsung, Aukey and Xpower charger, I don't get the speed of the QC 2.0, but it isn't suppose to as the S2 is not QC 2.0 compatible, but it does charge pretty quick, it also charges my ipod 4, and my nw-ZX2 work without any problems.
I get the "slow charging" message when using the Galaxy Tab S2 bundled charger.
If I use the charger from my Note 4 (Exynos) I get faster charging and no "slow" warning.
Did Samsung bundle it with the slow charger??
I can confirm that samsung did in fact bundle the tab s2 WITHOUT a quick charge usb charger.
I also thought the tab s2 didnt come with quick charge. I have extremely slow charge times but my battery lasts for DAYS... I can fully charge it, put it in airplane mode and check on it after 2 days and be at 98-99% battery.
I also use the quick charge cable AND the quick charge usb adapter that came with my note 5 and the tab still slow charges..
Here the same problem use Samsung charger and cable charge from 20% to 100% in 6 hrs and when use HUAWEI cable with Samsung charger It charged in 2 hrs
I guess Samsung have poor quality cable *-*
