On the stock batter it shows you 3.7vdc and 5.18Whr...
Under battery calibration tool it shows me that I am currently at 4119mV at 100% charge.
I am not to well informed on volt and watt conversions, but shouldn't 4119mV be closer to 5180?
I=current (Amps)
E=Volts
P=power (Watts)
I x E = P
P / E = I
etc.
5.18 W-Hr / 3.7 V = 1.4 A-Hr (= 1400 mAh, the rating for the stock battery)
3.7 V is the nominal voltage for a LiIon cell. 4200 mV is the voltage for a fully charged one. To prolong battery life, the charging is cycled, it will charge to 4200 mV, then stop charging and drain to just under 4100 mV, then the cycle will repeat. It will show 100% charge while it's going through these cycles, even though it's really bouncing between about 93% and 100%. That's because people would get confused to see the level drop below 100% after it's charged, but still connected to the charger.
hmmm soo if my phone battery indicator says 4011mV.... but also says it has only 50% left....that is not right than ?
Nope, completely ****ed up. But I guess you managed to get it through those 4 years ??
Is charging time really slow for the Xperia Ultra?
Mine charges about 35% per hour.
It takes 3 hours to fully charge my phone. Coming from a Samsung Note 2 which charges completely in 1.5 hours, I find this really slow.
Charge current 1Ah is normal.

Try charging in Airplane Mode.
Well, there's two sides of fast charging.
One side, you need little time to charge (of course lol)
On the other side, the faster the charge (1,5 hour of full charge on lithiums is VERY fast) the more strains the battery experience in a charge cycle, hence shorter battery life. Since XZU battery is non removable, let's assume that sony play it safe..
Oh and CMIIW the charger for note 2 is rated at 2A DC output right (or was it the S4? I forgot)? That's higher than XZU's 1.5A DC output charger (CMIIW, haven't received my XZU yet).. So 1.5A DC to fill a 3Ah battery is about 2.5 hour, depending on the charge controller of the handset.
- Battery is 3050 mAh
- Charge current is 1 or 1.5 A(h), AKA 1000/1500 mAh
- Charging time for a 3000 mAh battery = (1000 mAh (1 A(h)) x 3 = 3000 mAh), or (1500 mAh (1.5 A(h)) x 2 = 3000 mAh)
TL;DR: It's normal. The bigger the battery, the longer it takes to charge.
You can use a 2 A charger, but it might damage the battery, or worse. Charging through a USB is also much slower (around 500 mAh)

That is incredibly fast already for a battery of our size.

Actually, charging lithium requires specific algortihm to maximize the battery's lifespan and capacity (CC-CV algorithm).
That's why phones manufacturers use "fast charge" marketing gimmick to charge your smartphone up to 80% capacity in just x hour. It is not actually "fast charge". It's just the CC phase, where the charging controller makes full use of the adaptor's output current. After that comes the CV phase, where every lithium batteries, no matter how big their capacity is, are in the mercy of current-voltage law... That said, charging a 3000mAh battery with a 1.5A adaptor will take more than 2 hours.
Technical things aside, charging (most of currently used) phone's batteries from "zero" to full capacity (which, to a certain extent, doesn't matter how big the battery's capacity is) in just 1.5 hours is near the limit of fast charging.
Thanks for the info. Takes me more or less 2.5 - 3 hours.
Now I know it is normal, thanks to your explanations. I was used to the Samsung Note 2's battery (3100 mAh) and it took just 1.5 hours to fully charge. I remember it being 1% increase per minute. Didn't know that the Samsung charger was 2A DC. Yikes, I sometimes use that to charge other devices.

Interesting! We learn something new every day! Thanks
My device charges to 60% fast but after that is takes forever to get to 100 % whats app with that ?

Well for one thing, when you charge the battery, what you're doing is increasing its internal voltage. To charge the battery, you have to supply a higher voltage than the battery currently has, and so the higher the battery's charge, the slower it charges, all else being equal.
However, all is not equal, because at a certain point, the charger slows down the current it is delivering for safety reasons. These two things combine and the result is much slower charging after a certain point.

i used the charger from galaxy s4 ( 2A) to charge my xperia z ultra but it didn't charge it faster than the sony stock charger ( 1.5A). Weird. it seems that the phone doesn't allow more amps to be transfered. thats ashame cause if you use the phone while charging it doesn't charge almost at all. the consumption is higher than the charge rate
I just compared samsung 2A charger and Sony 1.5A on stock KK 4.4.4 (108). Samsung charger is better if you have limited time.
Is it real that charging with a higher current is bad for battery ?
Samsung 00:00>1%
Samsung 01:00>53%
Samsung 02:00>93%
Samsung 02:26>100%
Sony 00:00>5%
Sony 01:00>45%
Sony 02:00>80%
Sony 03:00>100%

Debatable, but I don't know that much about battery tech, so i'm not going to speculate. I'll keep using the stock charger though, since the Ultra has an internal battery after all, and I won't risk damaging the battery by using a different charger.
I'm using the DK30 dock btw, and it takes 2 hours from 0-100%. Do you have the dock, or are you using a regular cable?

Using regular cable. Today I'll visit local Sony store for DK30 and I can repeat the test with the dock.
1 hour difference is great,
Anyone idea why my mobile is charging slow?
I have bought Moto E I the middle of the summer, I was using 1A charger and normal charging time was 10 minutes =10%
Like week or two I read about Qickcharge 2.0 and I saw there, Snapdragon 200 is supporting this technology. But then I opened official site with list of supported devices and Moto E was not there... So I didn't bought Qickcharger but I started using 2A charger and results were pretty good, 10 minutes =20% of the battery. But today I noticed significant decrease of % per minute. I am still using same Samsung 2A charger (from nexus 10) but in 10 minutes =6%. I don't know what happened... Isn't Moto E supports 2A charging?
I tried also old 1A charger which I used to use before. Before I charged Moto 10min = 10% but now with same charger I charge 10min = about 5% :/
And I also tried 1.35A Asus charger and in 15min I charged 13% which is the best result but still worsted than result with 1A charger before :/
Could anyone help me? :/
Hi guys! The phone is taking over 2hrs 30 mins to charge from 0 to 100% with the supplied 5V 2A charger. Is there any way to improve the charging time, considering this is very slow?
Not really as it doesn't support fast charge

yes that was a disappointment to me too... Previous phone was a Motorola Nexus 6 with fast charge, it was charging from 0 to 80% in like 30mn :-/
Will miss that. This said 8X battery really hold for 2 days, so just not forgetting to put it in charge one night every two and problem solved.
Well will using a 2.4A fast charger destroy the battery ?
For me charging:
- from 10% to 80% - 1h 5min..
- from 10% to 100% - 1h 59m..
Checked it by AccuBattery app.
I use 5V 2A/9V 2A oryginal charger. Only that my phone has 5000 mAh of capacity, not 3750 mAh. My phone Honor 8X Max support fast charge, Honor 8X does not support fast charge.

I connect my phone to charger every about 10 days, but I use my phone only a little...
I didn't know the 8x does not have fast charging... I have the 8x max and it has fast charging at 9v 2A
Hi Guys
Got the S22 Plus in Snapdragon variant and the phone doesnt charge nearly as quick as reviews online taking 1 Hour 30 mins for me, and yes I have fast charging enabled on the battery settings
I have read couple of articles and seen few videos about it. It does take 1 hr 30 mins to get fully charge.
I'm using Charger came with my S20plus along with the cable came with S20plus.
My phone charges up in 1Hr 10min max.
It depends on the room temperature and the phone temperature also I think.
However buying a 45W charger for S22plus is a waste of money.
Nvm
Usually, those charging times they advertise are from 0-80%. The way lithium ion batteries charge, they all slow way down after 80% . After that you may as well be using a 5w charger.
Get 45w charger I usually getting around 40minutes to 90%+. you will see Super Fast Charging 2.0.. but since android 13 update I only see Super Fast Charging although it charge as fast
Honestly, I am using my laptop type C charger. It shows as fast charging and max it takes is 1 hr 15-20 mins for full charge. So I think you are good.
