Slow charging

I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.

Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?

I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.

As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.

Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.

Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.

hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).

the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.

This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.

Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.

Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.

Hermes Charger

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....

Battery -6 hours charging - 49%! What is wrong?

I have another problem with battery. I charge TP for 6 hours. after that time it still showing CHARGING, round light bimkning and when I enter battery, it shows 50-70% and charging! when I make soft reset it show full and stop charging, anyone knows how to fix this?, I'm worring about my battery I have oryginal rom. Thanks for reply.
I know that it is in other tread but I try to find solution

Are you using the supplied charger?
This happened to me when I tried to charge it with a Motorola V3 charger.

yes, the original charger is one amper powered which is very strong, all other chargers I have in my car or whereever output much smaller amount in milliampers (starting from 200 mA even). BUT never forget that slower charging is always better to preserve battery durability

oryginal delivered with TP

How long did you charge it the very first time?

dificult to say, i thing over 8 hours, but battery is really ok, it keeps 2-4 days.

i think i got close to an hour wait for 3/4ths charge
so prob about an hour and a half for max???

I had this same problem yesterday. It was at 30% after 4 or 5 hours of charging, then after I reset it, it was at 100%...

had same prob. Fixed after hard reset

HARD reset help

I had this problem and was hesitant to do a hard resent and have to reload and re-enter all my settings.
Turns out I was charging through USB that was connected to a cheap hub that didn't supply enough power to charge the phone. Connecting my sync-USB cable straight to the computer fixed it all.
Silly oversight but it might help somebody with the same issue.

hmm, mine started doing this a few days ago...i do remember I used to have the usb charge hooked up directly to the computer but i noticed it was now connected to the usb hub. Let's hope hooking it directly to the computer fixes it...i can't rmember when i switched it to the hub ;p
EDIT:
yep, connecting it directly to the computer fixed it
Thanks!

even charging throught eh computer is slower than plugging it into teh wall. the usb charging only sends SOME of the power to the phone and therefore takes much more time than charging through a wall outlet...

Same thing happened to my wife's TP. Using Stock 1.90. When charging it would reach 85% and stop there irregardless of how many hours I charged it after that but after using the TP car charger it would resume the charge and reach 100%. So the TP would be normal for a few days and then the same problem would occur. Don't know why though but I would use the car charger to normalise it as soft resetting doesn't work.
Where as I'm using the Stock 5.05 euro without any probs....

i to have been having problems with battery life, and ive noticed as previously mentioned a significant differance between usb and mains charging. i charge my tp every night and last month i started to leave it on the usb rather than putting it on the mains in the bedroom. it was then i noticed a drastic drop in batterly life, after a full day at work (12hr approx) and average use ( txts/emails/games/vids) i wa left with only 10-15% battery. but when i returned to mains charging the same usage now leaves me with 45-55% battery. so now i just stick to mains charging through the night. just my 2 cents

This is what solved my problems...
Turn off your phone and plug it in to the wall, wait until it is fully charged. Then you can turn your phone on, and use it like you regularly would, but use it until you run out of battery, I mean 0%, it turns off randomly. Don't charge it again till it's fully drained.
Then fully charge it again, this time don't plug the phone back in until it reaches 1 or 2%.
Hope that helps!

yep, that's because the USB does not deliver the full power to teh device. that's why charging it via the supplied charger is much more efficient and powerful and lasts longer. USB should not be used to charge unless necessary for this reason

I had the same problem with I first got my Fuze. I even tried the ritual draining and recharging but nothing worked.
So I called AT&T and they swapped my battery for a new one. Problem solved.

Not Charging whilst on!

Amazed at long battery life, almost 5 hours SOT time and 50 % battery usage. Just plugged in OEM charger and it's not charging. Going to settings/battery, it says, plugged in, can't charge right now. The phone is cool, and has not been used excessively. I powered it off, and now it's immediately charging ok. Powered it back on and now it's charging ok...??? Any ideas folks? Anyone seen this before?

@gsw5700 Did you ever get this sorted?
I'm having the same issue, have sent full repro dumps to OP (in response to my filing a bug), but I haven't figured out why we're "the few", although the reports are growing, in the OP (manuf.) forum.
I can charge with my Dash charger, most times, but almost never with a regular cable, even a 2.4A source, but mostly my Qi receiver, which is good for about 550-700ma. This setup had worked on my 5T (my wife continues to use it to charge, it's just "part of the phone" for her).
Frustrating, REALLY frustrating, for a new, flagship device. I might exchange it, but I suspect it's s/w, because if I reboot, it'll charge low-current, one-time, until I stop charging, then a reboot is the only thing that allows it to work again.
"Reboot to charge", it's almost a feature, NOT ;-]
I too have really awesome battery life, once it's charged, it's really solid all-day, easily, that part is great, once I can get it charged (non-Dash) ;-]

Hi, this only ever happened once, on the first day or so that I got the phone. It's fine now, charges really fast and cool on the dash charger. Also charges fine on standard chargers, just slower

Hmm, okay, well thanks for the update.
I'm sending mine back, something "weird" is up here, and even if it "feels" like s/w (the reboot "fixing it once", rinse/repeat, for example), I'm not taking any chances.

Fast charging using normal adapter?

As we all know, the charger xiaomi provided in the box does not support fast charging, although it is quite good. For fast charging we have to use different adapters or powerbanks that support it.
Yesterday when I was using my normal charger, it suddenly showed quick charge and two lightning symbols in the top right corner, which indicates fast charging, that I usually get when using my mi powerbank.
First I thought it was a software flaw but sure enough, my phone was charging at a much faster rate and was heating up similar to when I charge using powerbank.
Unfortunately when I removed the charger and reinserted it, the phone charges at it's normal rate, and I've been unsuccessfully trying to repeat it but it's not happening.
My device is completely unmodified, stock unrooted rom and bootloader locked.
I think this means that the normal adapter might be capable of fast charging but xiaomi has disabled it, something worth looking into.
Also I know the phone charges quite fast below 50%, I saw this effect while phone was at 69% and reached 72% in barely 3 minutes or something.
Unfortunately I did not have the presence of mind to take photos as proof.

first of all if you are using charger which comes in box with the phone, its not a fast charger its only 5V2A.
2nd it can't charge at pace compared to fast chargers as it can only provide 2A at max or it may be faulty
3rd it may be software bug just showing quick charge
and in the end you said it charged from 69 to 72 in 3 min. i can say its not fast charging because my charger 5V2A which came in box also charges at same speed you are saying. it normally takes around 1 min for 1% increase but depends on various factors like load being used currently by the phone.
sometimes when data is off or battery saver os on it charges more quickly as consumption is also less so it charges fast.

It was 2% in one minute, I've attached a ss from telegram group of violet where I reported this for proof. My data and wifi were on, and I've enabled always switch on data for faster switching in developer settings.
Even now it's currently happening, but the rate is very slow, I think it's probably a software bug like you say, any idea why this is happening?
Edit 1: That Telegram ss is from the day where I first created this thread, not today.

i know the time is different but why didn't it increased in screenshots you uploaded the time already changed in both of them but battery remains same 69%. its showing fast charging but its not working I guess
plus maybe your battery health is not good.

Quick Charge 3.0 issue

Hi all,
The last couple of weeks I am having issues charging my phone (HTC U12+), at first I thought it was the charge or the wire, today I got the Mrs phone, which is the same as mine, brought on the same day directly from HTC, running the same firmware, then I got a few different charges, some Quick Charge 2.0 Samsung Genuine, and some Quick Charge 3.0, HTC genuine, and a variaty of good quality wires, and they all work as expected on her phone, Quick Charge 3.0 charged fine up to about 3000mA, I plugged in my phone, at first it shows about 2500mA, that's with the Quick Charge 3.0 chargers, then withing less then a minute I goes down to about 1000mA, and it shows high mV and high temp, please see attached screenshot, the app I have used and always use to test it all is AccuBattery Pro, and by the way do do know that tge battery charges slow for the last 20% or so, but as you can see in the screenshot the battery is bellow that, and when I started the test the battery was at about 25%...
Is the battery on the way out or what?
Thanks

Well, charge speed depends on several parameters.
If your battery is pretty full it's going to slow down charging.
The fastest charge I seem to get is when it's really low on juice.
