Hello everyone. My phone is xperia z1 and it has an original charger. Its output voltage is 5v and amp is 1.5A. While I charge my xperia z1 with the original charger, max 600-800 mA current is delivered to my phone.
Firts question,why is not max output current (1.5 A) delivered to the phone despite the adapter is the original sony adapter?
Second question, may I buy a fast phone charger instead of sony original charger ? And to charge xperia z1 with a fast charger, can be bad for the phone?
Please, answer my all questions clearly who knows about them
Best regards,
Sarkhan
slow charge = good battery life
fast charge = worse battery life
use the original, have you ever heard of the internal resistance of a battery? it's also a fact that we can't charge a battery very fast. battery will get heated and then exploded maybe if the current is higher and the temp becomes too high. go on with the original one
Thank very much friend

From my experience, there is a regulator in the phone that ensures the battery won't heat up or overcharge.
Don't forget that part of that 1.5 A dissipates as heat in the environment.
My original charger when the battery is low, goes to about 1 A and as the battery fills it goes like yours at around 600 to 800 mA.
I have tried charging it with a 2A Samsung tablet charger but again, when battery is low it goes at about 1.1 or 1.2 A and when it fills it is around 900 mA to 1 A. So the gain is very small.
And it is true that with the Samsung charger it heats a bit too much, so hotter battery is less battery life, AFAIK.

I intend make a HD2 battery direct charger by a charger of O2 Xda IIs. The origin charger of HD2 has 1000mA current, IIs - 2000mA. Have any problem when we use a hight current charging?
Who know the answer?
noproblem if the current is not more than 5.5 volt
Is there other charger better? quicker charging..?
hd2 charger is 1000mA on 5.5 volt. SO there should not be any prob..
I'm using Nokia Charger AC-10X I think it was for N97, and it's pumping out 1200mA fast charging...
1+
I would also like to know a direct battery charger for HD2 batteries. I have 3 and it's annoying to charge all three before I travel. This would be a great find.
I've written a nifty little utility, a while ago, originally for my Xperia X1, but it works beautifully on the HD2 I just got. You can use the app to tell you if there is any difference in the charging rate. I do recommend, however that you charge from below 80% as the HD2 will start reducing it's charging rate automatically to make the cycle more delicate at < 90% to reduce the chances of damaging the battery. My HD2 at 50% battery will recharge at a rate of ~700mA on the regular charger.
P.S. I've never submitted this App to anywhere but it is free to use, mostly because there is a link to my Web Page and my web page hasn't been updated since I started the thing. Never seem to find the time since I do nothing but web work and Gran Turismo 5 seems to eat up my spare time lol. Evil game.
P.P.S. I know this won't help you if you create a direct charger for the battery, but if you use a higher mA micro usb charger, you can always test the difference in the phone itself. I have noticed you can also increase the charge rate by using airplane mode. Just a thought...
I've notice many ppl discuss about their aftermarket battery were unable to
reach 100% when using standalone aftermarket charger.
Just to point out that the S3's battery is using 4.35v cell instead of the usual 4.2v cell.
Most standard charger stops at 4.2v thus they'll stop at around 90%.
If you're looking for standalone charger. Best to look for charger rated at 4.35v.
(I rooted and change kernel to undervolt the CPU. the result is excellent, anyone who want longer run time should do it)
Every charger is 5 volts. The phone sets the charge voltage, not the charger, which is 5 volts.
The OP is referring to the voltage of the battery cells, not the USB charger (which is always 5V). The battery on the GS3 is in fact a higher voltage than most other phones (like the GS2). If you use an offline/standalone battery charger that does not charge to the full voltage of the GS3 battery the battery will show about 90% charged when you place it in the phone.
i wrote a review a few days ago on a stand alone charger i bought.
so far no problems with it charging my battery to 100%.

I plan to use this phone for many years, so I'm worried that the fast charging might do damage to the battery in the long term or shorten its lifespan, so I'd rather charge it "slower". Is there a way to turn off the fast charging in the OS? Or is my worry unsubstantiated?

You made my night... Slower charger kills battery not fast charging.. fast charge save battery to be honest. And you dont have to be worry since the batteries now are LI-lon . Go get info in google about the batteries . All i can say you got infos wrong.

Agree with previous post. But if it makes you feel better, just don't use a dash charger...
Very simple.

OK. I didn't know.
I was speaking from my past experience with Samsung Galaxy Note 4. I bought couple of original Samsung batteries and rotate them throughout daily usage. I noticed a significant difference in battery life comparing the ones that I used fast charge on vs the ones I didn't. After that I stick to NOT using fast charge.
Of course, that's nothing scientific. And Samsung uses a different fast charge mechanism (higher voltage) than OnePlus (higher current), so there could be difference there too.
Because Dash Charge seems to be re-labeled Vooc charging from OPPO, I can tell you, that the last two years with charging minimum one times every day, there is no bad effect on the battery (still the first one).

Samsung devices are notorious for killing batteries and its more likely hardware than it is the battery itself, u will be fine
I have a similar question: does it make any problem if I leave the phone in (dash) charge for the whole night? I mean, if I sleep for 7hrs I'll have 1h of fast charging and 6hrs of nothing-but-charger-heating. Will this habit hurt the phone's battery or the charger itself?

I use Samsung 1.5 Amp charger and keep my battery between 40% to 80%
I think these are best for long term usage.

that's the problem of the charger or the phone itself. thecharger is designed not to charge when the battery is full. What I want to say is you experienced an accident and sorry for you.
The most serious threat to the battery is high temperature. OnePlus 3 reduce the charging heat by its dash charge. The dash charge pushes low voltage directly to the phone, which mitigates the heating problem by pushing high electric current and making the voltage transition process in dash charger. Most of other phones still use high voltage because they fail to create high current. recalling the physics in high school, the power is current multiplied by voltage and energy equals to power multiplied by time. than you would understand the powerful feature of dash charge

The power is current multiplied by voltage so what's the difference between high current mutiplied by low voltage versus low current multiplied by high voltage ?
2V x A = V x 2A

qc3.0 uses low current and high voltage. Dash uses high current and low voltage. As a result, they have similar power and both charge quickly. However, the heating problem is more serious for qc 3.0. The difference of the battery voltage and charger voltage is the leading factor that determines the transition efficiency. The bigger the difference is, the more heat charging process generates.
So~ you could look up for qc3.0. for mi 5, it has three adaptive mode: 5V2.5A、9V2A、12V1.5A. for dash, we have 5V4A

There is no problem with leaving your phone on the charger. I do this with every phone since years.
If people experience something bad with it, their phone or battery are broken. The current tech just keeps the battery at full capacity once it's full. Never had any problem.
So many "opinions" but mostly incorrect. The answer to the OPs question is that you don't have to worry about quick charge destroying your battery. It will not have significant impact on your battery capacity. I would have been more worried about breaking the usb type-c port(see point 2 below). All things considered, after 2-3 years you will probably buy a new phone anyway and also you can always buy a replacement battery cheap. But you can simply use a normal charger which delivers <3A with 5V so you don't have to worry about anything.
1- Slow charge does not damage lithium-ion chemistry batteries. You can read about lithium-ion charging here. But neither fast charge will damage lithium-ion as long as the battery temperature is not extremely high. Also temperature at different charge stages effect the capacity decrease (source) But you will be fine as long as the battery temperature is less than 45C. The charging IC should stop the charging process if it exceeds it anyway.
2- Qualcomm's quick charge is much better than voop/dash charge from an engineering standpoint. This is why also USB organization's power delivery (PD) standard uses similar scheme. The problem is the cable and the connector. The maximum allowed current at 5V is 3A with usb type-c connector (source). If you provide more current, you need to use a thicker cable(dash/vooc cables). But you can't change the connector, and it may damage your connector in the long run to use 3+A currents to charge. Because there is a contact resistance (R) and the power lost in the connector is square of current (I) times R. Meaning R*I^2, it will wear off the connector faster. This is why some companies with some engineering skills opt in to use higher voltages instead of higher currents.
3- You can't push more current to lithium-ion battery than it accepts. The maximum current is voltage delta (between charging voltage and battery voltage) divided by internal resistance. This is why you can charge empty battery much faster. If you use an app like Ampere from play store, you can see the voltage of your battery before and after you plug in your charger. If you plug in a normal charger, you will see that it goes up a little bit. If you plug a quick charger it goes up to ~4.35V
4- Yes, there is conversion inefficiencies for quick charge inside the phone, and it will warm up the "phone" and battery only indirectly. The conversion IC are normally >90% efficient (source). This does not mean that your battery will be destroyed. It is perfectly fine to charge lithium-batteries with up to 45C temperatures (source).
4- If overnight charging killed your battery, your battery was faulty (or you had 3rd party battery?). The battery should be capable of holding 4.35v charge. You would need to store battery at 4.35V full charge for over 3 months to loose 20% capacity (http://batteryuniversity.com/learn/article/how_to_store_batteries). Having full charge few hours overnight won't destroy it unless your battery or device is faulty.
With all this information, I would rather opt in for USB-PD/Qualcomm Quick Charge solutions than VOOC/DASH solutions. I think eventually only USB-PD will remain and everybody will use it as a standard only.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Sony Xperia XA1 Ultra can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Charging speed if you look at it in how much time it takes
It is terrible..
Before I bought the phone I saw it takes from 2hours and 15minutes for some
And some reported about 2hours and 45minutes
For me with the original charger and the sony cable it took 3hours and 5minutes
Horrible
But if you dont look at the time..it is charging slow but it is not getting hot while charging...not even warm
ITS COLD
So this will be long term good for the battery lifespan..
Can not have it all can you LoOoL
The phone charges from dead in about 2 hours 15 minutes for me using a 2.1A USB outlet. I don't know if it's actually charging at 2.1A or not, but that's nothing for how long the battery lasts in the first place. It's also a high capacity battery, don't compare the charge time to something like an Alcatel One which has a 1300mAh battery. The XA1 Ultra has something like a 3600mAh battery.
The wall charging adapter they give you with the XA1 Ultra only charges at 1.5A. IMO they should have given us a 2.1A wall adapter instead. But faster charge times = less battery life so it's a trade-off. Most people won't keep the phone longer than a couple years anyways, so what does it really matter?

Yes, I do know that it reduces the lifetime of the battery
But the thing is.. it is in the spec of the phone written that it can be fastcharged
Not with the charger wich comes out of the box
But you need to buy fast charger
So I did that..
And it is not fast charging at all..
That is what is bothering me..
Why do you write something in the spec wich is not working
Or if it is only for china or taiwaniese devices thay MUST write that down
So that you do know your lets say europe device will not fast charge..
I could try it with and charger with higher output.. maybe that would work..
But just bought original from sony wich is not working..or the ability to fast charger
is not working
I googled a lot and I am not the only one..you could see everywhere even on
Sony forum people complain like me buying something that is not working
The best sony answer is...
''Do you use the right cable''
And yes we all use the cable wich is needed to use to fast charge..
But yeah.. paid for nothing
Hello guys,
To offert at my battery the best treatment I'm looking for a lower amperage wall charger for my Pixel 2XL.
Between 1 and 1.5 Amp it will be excellent. I read some interesting suties about battery life and how manage it and fast charge is part of that.
Thank you all anf have good evening.
I am sure it will charge on either one, but how fast who knows? If you are rooted and have Magisk, download the ACC module and you can control your charging that way instead.

I am an electrical engineer, and have some knowledge about how Li batteries function.
I have always wondered this, I always see people mentioning that slower charging is better for the longevity of Li-ion batteries. There is always a trade-off here. Slower charging also means the battery takes much longer to charge, and the battery stays hotter for longer period of time, which should affect it's lifetime. Fast charging also does the same thing, but the temperature is much hotter but is exposed for shorter period of time.
Now these is merely a speculation on my part, I don't have any theoretical or experimental evidence to back this up - I think regular 5V 2A charging is a balance between those two scenarios.
Also, I recall that the peak charging current is limited in P2XL, so using the stock charger shouldn't harm that much either.
Pixel 2XL is my first smartphone who do not Come hot when it charge so...
But I know that high temperature are not the best things for battery in general.
And about the level of charge ? Some people said they stop at 80% to manage battery

I use a 5 watts charger and the phone stay completely cold during the charge process.
Also there was a recent 2017 scientific paper that tested what degraded the battery. It's a really interesting read with many tested model.
https://www.researchgate.net/profil...e-model-under-different-charging-stresses.pdf
Number 1 cause is high battery voltage at the end, second one is battery charging speed. Any speed faster than 1c will degrade the battery much faster.
This is why i charge at 5w plus stop charging at 80% (unless i know I'll need 100% that day, where i fully charge, but for my usage 80% is more than enough for the usual day).

You have to wait for about 10 cycles. It says in the application something like that.
