Hello,
How can I tell if my HTC One Max is actually charging at 1.5 A? I've had the phone for about 4 days now, and it charges soooooo slowly. One night/morning it took almost 6 hours to fully charge from around 15%. This can't be right. There are times I've just sat in bed (Thanksgiving Day, for example) doing some light texting and light web browsing...all with the official 1.5 A charger connected, and at times the battery level DECREASED, even while connected to the charger. I have the brightness set to auto, and the screen timeout set to auto. This can't be right...
I downloaded a couple of apps from the play store that try to estimate the charging speed. Battery Indicator estimates that my phone is charging at a rate of about 14.3% per hour. It's also telling me my phone will take 47 minutes to get from 88% to 100%. WHAT!? Another app, just called "Battery" says my phone was charging at 684400 mA...then it changed to 219900 mA. (Of course, neither of these numbers make sense, either. That would be 684 amps or 219 amps...enough to blow something up.)
Again, I'm using the official charger that came with the HTC One Max saying it supports 5 V, 1.5A. I have other chargers lying around different rooms of the house...there's a chance that I'm not using the actual USB cable part that came in the box (it could be mixed up with an older one I had lying around), but would that affect charging speed?
Thanks for any help you can give me. I'm about to call HTC now.
you should really try it first with the OEM cable and charger, but it should not take 6 hours..if it does with the HTC cable/charger, take it back, its defective
assuming you are on stock, and not rooted/tweaked

1.5A charger charge 1500 mAh per hour so it should charge in about 2 hours and a half..
You have one problem of two ether your charge isn't good or your
battery.. if your phone run out of battery very fast then it's your battery else it'sthe charger

I had a friend of mine get a new HTC One and it tooks hours to charge.. it was the charger which was at fault. as said in the previous post. if it also discharges fast then the battery is at fault, if it only takes time for charging it is definitely the charger. i am guessing you have found the solution already lol

I think I figured out the solution: In any scenario, I was using the charging adapter that came in the box. The variable that changed was the USB cable...since I have several lying around in about every room of my house. It seems only that the USB cable that came in the box will charge the phone quickly...around 3 hours and 20 minutes from completely dead to 100%. Any other USB cables seem to charge at about half that speed. (And of course, charge time suffers when the screen is on and you're using the device.)
But I still find this really odd. I assumed all micro USB cables were created equal. Perhaps not. Am I missing something here?
That's odd. This phone has the quick charge component/feature from Qualcomm, but that should not make any difference based on the cable.
well may be the other cable were not plugged in properly and did not reach the charging pins in the correct place? Do you notice a difference in attaching and detaching the cables?
for whatever reason, factory cables ALWAYS work best with the device they came with..
sometimes aftermarket cables are ok, but you can never be sure...
If you can, use the cable and charger that your device came with; that will always be best.

I had the same issue. I was going to use my old S4 cable cause it is longer. It gave me a notification telling me to only use the charger that came with it. Was the cables fault. My guess is it is using an extra pin to tell the phone it is the correct cable sort of like how OTG cables work.
Hello,
when the tablet was in the charger with 1000 mAh and my GF was playing plant vs zombies 2, it was not enough and was dead in 2 hours. So I put there the official charger 1500 mAh but then still it was not enough and was dead again.
Right now I tried to turn off the Location, Wi-Fi and she is playing. But is this normal??? Jesus you should be able to play with all the functions turned on and in the charger, not???
Edit: so it was emptied again even with everything off...
Edit2: i will try the origin cable because I used a different one

Did it show the charging icon while she was playing the game? I'm curious if it might be plugged but not recognizing that it should be drawing power from the charger...
Because charging cables are differently wired, you MUST either use the original cable or a cable which is definitely known to have the same wiring as the original one.

Differently wired how? I didn't realize there were wiring differences, please elaborate if you can, feel free to get technical.
I tried plugging my Z2 Tablet into a USB cable from a powered hub (computer off though), which I've used to charge my phone and my Kindle, and I know it wouldn't have much power, but it wouldn't charge at all, no charging icon, nothing. I've had no trouble charging it with a dedicated charger though.
~Troop
So yes,
1. the charging icon is there
2. I even logged the history and during playing the plant vs zombies 2, the power is oscilating around +- the same level but still going down slowly as a trend
3. I tried today to get the power back to 25% and now I am charging it. I have the battery widget where it shows getting mA about 390 to 890 maximum. But even it is the original charger, original cable and the charger is 1500 mA it seems that the maximum level is 890???
Can someone else try Batter monitor widget what they get from it???
Edit:
It sucks. It announced even today DURING charging from the original charger and cable that the charging is not strong enough. Wtf?
Edit2:
Here they say it is charged under 3 hours. Not my case :-/ http://www.digitalversus.com/tablet/sony-xperia-z2-tablet-p19609/test.html
Ha, that is really funny. I am from the Czech Republic and called the Sony support. They forwarded me to Xperia support. At Xperia support the girl said that she cannot provide me exact information because official release date here is 8th of April so she doesnt have the manuals etc.
Then my type is 511E3 which she again was absolutely no aware what is the type because I should have 621 or maybe 521 but not 511.
So I can try the support line next week with the question how many mA should go to the tablet during charging.
But what she said was also that the charging time could be up to 6:20. But more than 6 hours? Maybe it was about the Z1 model? And also told me that playing games with the charger will still result in draining the battery.
I need some other guys here who can test it with playing some games and check the mA during charging...
I don't have a Z2, but just wanted to mention that cnet saw the same (no charge while playing) in their review: "[..] the tablet lost power even when it was plugged in to the mains" http://www.cnet.com/products/sony-xperia-z2-tablet/2/.
I never experienced any of this. There's probably a problem with your unit.

And have you tried to charge it during heavy playing of some game? Which game, how long?
Can you test how much mA are you getting from the charger inside the tablet (battery monitor widget can do this)
I tried it yesterday playing "The Cave" for about 1 hour. Tablet was charging using a four port no name charger and a different cable the that the one provided.
I did not really check for anything , I just noticed the tablet got mildly hot.
I did not measure the current while playing, but I did earlier this week-end though.
I tested 3 chargers plus the provided one. A Galaxy S III charger, An ASUS TF300 and the 4-port no-name I used yesterday.
If I recall correctly I got around 0.9A from the GS3 and original charger and around 1.2A from the TF300 and 4-port ones.
I do some more thorough testing and let you know. I use a device on the charger output to measure how much current is coming through.
How long do you guys charge the tablet? I started with about 19% and to full 100% it was like 7-8 hours. It was turned on without wifi (stamina mode). I will try to charge it while turned off but still it is strange...
I dont know. Battery life is ok but the charging sucks for me. Any ideas if it is just me?

Yawn... Please use the charger and the cable which come with the device (which I bet my grandma on you didn't)! Other chargers or cable have either too low current or wrong wiring (which disables fast charging) or both.
The charging time over USB is 4-5 hours, like the first generation Tablet Z.
Yawn, yawn, if you took a look then you would read from this topic that I use original cable and original charger.
If the battery is 6600 mA and charger 1500 mA then the minimum for charging is 4,3 hours approximately. And as I said my maximum charging is 890 mA. So either something is taking 600 mA during the charging or the charger is bad or the cable is bad or I dont know.
But if it is in the stamina mode and still the maximum charging is 890 mA then something is weird.
I am asking now for about 5 times. Could somebody test during charging how many mA is going into the tablet? (You can use Battery Monitor Widget from google play).
Neither Xperia support is able to give me clear answer because the Tablet was not officially released here (which is funny, I have it).
Thank you.

Dude, then simply go and exchange the charger if it is faulty. No need to make long XDA threads out of that.

Its not about charger. Or maybe it is. I want to know exactly how many mA are going to the tablet during charging. Nobody was able to give me the answer.It could be faulty charger, faulty cable, messy apps in the tablet (which I doubt) or whatever.
And Sony support, Xperia support is not able to give me clear answer to this. And also another guy in a review had similar problem. If we are in a Z2 Tablet topic then I supose that this is the right place to ask such questions... Not?
You can't just do 6600 divided by 1500. You are losing current all over the place when charging. It will probably be at least 50% wastage in heat, resistance in the wires etc etc. Also, the charger may say it does 1500, but that is peak when it's brand new under perfect conditions and the internal components will age and become less efficient over time too.
If you are using the tablet for a game, it will be running the processor at max power and drawing lots of current and all the heat it generates from the cpu and the battery during this time is wasted energy don't forget. If you want to battery to charge, you will need a charger that provides enough current to power the tablet and another 1000ma or so on top of that to charge your battery.
I bet Sony will state somewhere that you can only use it for low power activities like watching videos while on the dock if you want the battery to charge.

Thanks a lot!
So it just means that in general with the original charger you are able to get to 10-13% per hour. So in average usage 9 hours of charging, heh. I saw yesterday (have to check it at home) that I had also around 20% per hour.
But in general these figures are normal and the usage of a battery with a little bit more heavy tasks is not very good. And charging can take a LONG time. I tried to charge it while turned off and I think you can get there below 6 hours.

mm.after read all of reply above, it is quite weird that only get 800mah while using 1500mah support charging cable? Maybe can try better quality of cable and also the power source, it is very crucial to get that. I have try some trial and error with different cables and charging with my galaxy s3, i find that with good quality of cable, i managed to get 1000mah max , but if using with cheap cable or power bank, i only managed to get 400-800mah. even after a long time using the original s3 cable, it will reduce to only 600mah. So my advice is try charging with different cable and find the best cable to charge ur device, if it is 1500mah supported, so i think it should be support to 1500mah. Thank you.

No, it is not weird at all since the tests were done with the screen turned ON, draining half the power.
The first line, battery only, tells you how much the screen and semi idle state is draining, with brightness at minimum. Cranking brightness up to maximum increased an extra 2.5% per hour drain if I recall correctly.
Charging with screen off would be about 20% per hour, or 5 hours to fully recharge. More or less in line with what people is reporting.
Code:
Battery only: -721 mA (-10.79%/h)
Official charger (1500mAh): +719 mA (+10.76%/h)
So, 721+719= 1440 (+21%/h), pretty close to the rated 1500 for the charger.
I received my RN3SD 3gb yesterday. I was testing the charging rate today because I felt that it was charging slower today than yesterday. I used the program Ampere to check the charging rate. Market link is:
https://play.google.com/store/apps/...lay&pcampaignid=APPU_1_aYcvV5ziJMG0uATH1YSoBw
Well, in getting around 1000 mAh on an average with a max of 1300 mAh and lowest of 230 mAh.
I read somewhere that the charging rate should be around 1900 mAh. I would appreciate if I got feedback as to what the normal charging rate is for you guys (ideally, checked in the same app). And please let me know if I should be using a different app. Thanks.
info:
Unrooted ROM MIUI Global 7.2.2.0
Yes u r right, i m getting 1900 mah with 16 gb model ,ampere app is ok. Maybe try factory reset
Ampere showing 1.9k mA to 2k mA here.try check your cable and charger.
How that matter and what doest it affect ? Its about charging time or battery life ?
I'm gettgin 1550mAh
What was the battery percentage when you opened Ampere? When it's getting up to like 90 % the current goes down.

When I opened Ampere the reading always varies. Sometimes is 490 sometimes 1150, the highest I've got is 1650. The charging cable and the charger are brand new. Even tried charging from a USB power bank, got about 500mah. What can be the reason for this slow charging. These are all values foe when charge is less than 90%. What can be the reason?
Depends on what powerbank you have. Most don't support high charging rates, (although there are some more powerful ones from xiaomi and lenovo on the low end market).
On another note,
I am wondering about the maximum Voltage and Amp we can charge with safely? i tried 3 differennt ones; 5v 0.3A, 5v 1.2A and 5.2V 2A. All seem to work fine, with the last one i got about 10% per 10 min with a value of around 2100 Mahor higher , but i am not sure if this is a safe way to charge the device?
Does anyone know what is the maximum safe charging value?

There are regulators inside the phone that step down the voltage to charge the battery, i think it's a 4.35v cell but the phone will regulate the charge. So long as the USB voltage is within spec it's fine, many chargers have 5.1 or 5.2 volts to combat voltage drop with higher current over long leads or leads with small conductors.
mine about 1.900 mA
I am using the latest LineagOS. I thought Le Max 2 has QC3.0 support which should let it run at 12v charge voltage, but it does not.
The best it does is 9V and 1.6A (measured using usb meter) totaling to 14.4W. I tried the phone at room temperature, also cooled it down in fridge and tried again. Results are same. The battery was 1% - 3% at start.
Is this normal? I calculated and 14.4W if batteryt was charged to 4.35V makes roughly 3300mA which sounds rather low. I expected phone to go around 4100mA at least while charging.
More importantly, it never switches to 12V charging voltage. Is that normal?
my phone is going up to 4100mA while charging. On some roms you have to enable quick charge in your phones settings.
@LivingLing did you test with a program like Ampere or using a USB meter device? Because your ROM may be giving you incorrect values and it can't be trusted.
There is no quick charge option in LineageOS but I can see that phone is using quick charge because charger increase voltage to 9V. I am trying to understand why it wouldn't go to 12V

No i didnt used anything like that, just mentioned the values given by the Rom. But my phone charges Form 10% to 100% in like 15 minutes. So thats actually pretty fast in my opinion.
That sounds impossible, make a screenshot from the charging graph please. That would be something about 10A charging current...
I get about 4,5A when I activate QC on the EUI
@LivingLing Your phone must be broken if you can charge 0 to 100% in 15 minutes. You can't really charge a lithium battery very fast after about 80% and thats why quick charge implementations never talk about 0 to 100% charge time.
With lithium battery, most implementations set the input voltage to about 4.35V and battery charges as fast as it can pull power. This slows down when battery is near full.
I recommend you to get a USB meter, they cost few dollars anyway and quite cool devices.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Realme X2 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Quick isn't the word. It's amazing seeing how fast it charges.
Can it be charged with a 5 volt charger?
I think I have a problem with fast charging.
Yesterday while the phone was charging, electricity in my house was shutted down. When it came back, I can see than now, I charge 1 % on 35 seconds, instead of 20 sec before.
Could it have the battery damaged ? I doubt so, buty it's strange.
I tried when battery was 82%
Maybe it's quicker when battery is low ?
What's your thoughts about this situation ?
Thanks !
Edit : Okay, after 85% it slows down, but before it's okay

Yeah it slows down towards the end I'll go from 0-99 in 28-30 min then takes some time sometimes to get the last 1%. Battery life is also incredibly good.

Yeah battery life is outstanding..
Anyway, I have a little weird thing :
This battery monitor stats shows me different SOT than GSAMBatteryMonitor.
GSAM shows 2 hours more (wich I think wrong), and this delay grows while battery dercreases.
Do you have this app showing the same stats than colorOS battery monitor ?

I got my X2 Pro about 2 days ago. Charging speed is even better than advertised, as it takes less than 30 minutes to reach full charge. But phone usually gets too hot when fast charging. Do I experience this problem alone or do you guys too? Kinda worried about battery health in the long run if it gets too hot everytime I charge it.
Thanks before

Same thing here, so I don't charge more than 40 - 45% at a time.
If my battery is below 50%, I charge in 2 times with a 10 min pause.
Doing sop, you don't reach hoptter than 33 degrees instead of 38+
I can't seem to get a decent standard charging from 5V 2A chargers or Powerbanks, even a QC3 Powerbank only delivers 0,9-1A.
I only get about 900mA according to the Ampere-App. {On the contrary, I even get 1,8A from the original wall plug at 80% SoC).
Do you also struggle?

Can you disable fast charge (like in samsung galaxy note 9)?

I tried to use a 5 watt charger, and it works. Been searching in settings for an option to disable fast charging, but I can't find one.

Same here. I used a 9V 2A charger, and it won't go more than 1100mA.
I wonder if this is a detection error from the apps. I think they don't consider the dual battery layout and only display half of the true value.
The error that the app "charger tester" shows let's me think this or does support my theory.
All apps seem to not be able to show the correct current flow because of the dual-batteries.
I found the engingeering mode and can confirm that the phone charges with 5V 2A on dumb chargers.
And also supports QC 18W with 9V 2A
As well as the Oneplus 20W Dash charger with 5V 4A.

Super VOOC (and also VOOC) have their own protocol of charging mechanism. It's not the same with other quick charge method like Quick Charge 3.0.
You will not have VOOC charging if you are not using right adapter and right cable. You try use Super VOOC charge with other USB cable, VOOC charging will not work.
So when you using other adapter or cable, you'll got standard 5V charging max 2A.
