I have tried with my Samsung's phone charger (it is also 5V 2A), but charge rate remains same. Maybe my phone's battery going weak. But it's not even 2 year. It will in Nov.

And one thing more, actually it get fixed today after updating device. It charged at normal speed (an app showed 45% per hour), I usually don't use that app but I use it now to check charging status.
But now, it became again that slow. (App showing 12% per hour. 7hrs to full charge)

i don't think is a battery issue. also my battery is two years hold. i suggest you the original xiaomi cherger with a new cable. a more power charger is not compatible with mia3 tecnolgy. maybe the result can be a slow charging. are you on stock or custom rom? if you are on a costum rom probably is a software problem.

i'm agree with you

same problem here, but seem resolved with last update. I think it was a loading kernel module problem. the charger is good and the battery too. this is a kernel bug

i9100 starts charging even when disconnected, random reboots

Well, as the title says I have a Galaxy S II i9100 (Int'l Exynos Version) that thinks that it's charging even when its disconnected from the charger. It also heats up sometimes. When I connect it to the charger I never know if it's actually charging or not. the battery level indicator itself is problematic. For example, if it shows 90% battery level, when i reboot the phone it'll be at 70%.
Phone: GT-i9100 Exynos
Battery: Stock 3.7 V li-ion 6.11 Wh
OS: Android 4.2.2
Root: Yes
CM version: 10.1 Nightly (2013-04-23)
Kernel: 3.0.31 CM [email protected] #1
Thanks in advance!
Try dif nightly or clean usb port. Battery drop after reboot...dose it go Bk to right% after a while or drops and stays dropped?

Tried diff nightlies, no idea how to clean usb port(it connects to pc/probably charges, so i think the port's ok)
As far as the batt level goes, it sometimes begins to rise without charging
With 100% alcohol and ear bud. Be. Careful and make sure its powered off. Better still take battery out before you do it. If its rising after its ok. Reboot will cause battery to drop them go Bk up. Have you tried a different battery to see if yours is faulty?
Earbuds won't fit. Too big, port too small
Something sim would do. You get the idea
i cleaned it with a dry mini-brush thing, still problematic. Also, i found out that if i connect the charger without the battery inserted, phone shows charging animation.
Pass mate sorry
Happened to me to. I got a new USB port on ebay real cheap.

Easy to change.
flashed Samsung stock ROM(I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar) now. No difference. Hoping it isnt a hardware issue because I'm out of warranty and probably will sell this later for something newer so trying to avoid spending much to repair this.

[Q] My battery drains in 1-2 hours, takes longer to charge...

I have the stock CM10 rom installed, and it usually does something like this that only lasts for a few days and goes back to normal. But this has lasted for almost a month now. As you can see in the pic, sometimes its says charging but doesn't "gain" energy, and when it does in drains extremely quickly. When it is asleep or turned off it still drains. I tried charging it with a different cord, then with my computer. Then I tried using a GS3 cord & adapter, it charged faster, but I couldn't tell how fast it drained since I wasn't using it.
Do I need to replace the battery? If I do, will it cost a lot, because if it does I'm just going to get a Note or DNA....
Try using a battery calibration app, people say to use it when you flash a new rom. Also, it might be an actual problem with the battery itself. Try getting a replacement battery if so. But then again, before you do that try going to stock and see if the problem is still present.

once it charges I'm going to see if that will help. and my son deleted my stock rom (long story), so I'm stuck on jb/ics.
Also its recommended after you calibrate to drain the battery to 0% and then recharge to 100% afterwards. And as far as the stock rom goes, you can restore using Odin and download mode

wow it worked, the battery lasted from 5:30 to 7:10, a new record since I ever brought the device

How much screen on time did you get?

OPX Rapid Charging

This may or may not be new, if not then delete this thread.
From everything I've read, the OPX doesn't support quick charge/rapid charging. But my OnePlus X says it is charging rapidly when I plug it into my wife's GS6 adaptive fast charger.
This just happened so I need to give it an hour to see how "Rapid" it is. I'll report back the results.
If anybody has any info on whether or not this is legit please share. I'm confused ?
Currently running latest official CM13 nightly.

We have 2A charger, so when charging with this input current, it shows charging rapidly. This is not a fast charging. If you charge with 1A or usb, it wouldn't show.
It's a new feature in MM. It shows how fast the phone is charging. If you plug it in USB it will show it charge slowly. Currently blu_spark and boeffla kernels have option to enable fast charging (manually configure V and mA).

Isn't it quite dangerous just to manually increase voltage and ampere? You can't rely on that imo since you don't know the long term effects, or am I missing something?
I mean, the CPU probably supports it until some kind of level but since fast charge isn't activated.... (possible anyhow?)

Dangerous, yes. How much, I don't know.

IMHO, the dev knows what he should or should not implement for our device features. If they implement something that is means it compatible with our devices's hardware. But, use at your own risk.

Problems with the Quick Charge :(

i've been facing problem with the QC. I read that probably is the cable but i tried with S8 Cable and i had the same results...
I changed the rom (Aurel v12 / Cuoco v91) and didnt help me!
usually when i restart the phone th QC works but just for couple minutes after that goes down again!
i dont know whats happening! before it used to go under de 4000 MAh now is under 1600 MAh. :crying::crying:

Try to calibrate your battery

That's not the problem whatsoever, as he have a low battery percentage and that's how batteries work. When charged it's 4.3-4.4V and when they are put to use, voltage slowly falls to the cut-off point which is 3.7V on most Lithium-ion batteries.
The issue that OP have may be related either to an insufficient cable or software issue. I would recommend to charge while phone is turned off to see if QC works and if so, factory reset the device or change the rom.

It is possible to corrupt the motherboard?
Or it's just from the battery?
Means charge more before turning on
Press and hold the Volume Down button and the Power button with phone connected to charger. If it doesnt work try to connect it to PC, and try power it up with holding volume down button. When it turns on (booted in safe mode!) don't tuch anything just leave it for 5-10 minutes so battery charges to a couple of %.
It is probably bad battery. If you have charger supporting Quick charge 3 it shouldn't be a problem to start charging.
i had same problem i charged with turbo charger(motorola) and now its working
I just left my G5 charging for most of the day, using the POS turbo charger that came in the box, came back to a phone showing exactly the same as your photo.
Then I tried charging with my LG G3 (non-turbo) charger. Took about 3 and half hours but charged fine.
Last time I tried to charge my G5 using the turbo charger, it worked fine. And then randomly, it doesn't work at all. But the turbo charger allows works fine when charging my spare battery in its little LG charging case.
I hate this phone. G5 sucks. Worst phone I have ever owned.
This can happen on a variety of phones if the battery voltage gets low enough. The internal charging controller won't initiate charging because the voltageis below a certain
threshold. When it has happened to me I've connected the battery directly to a power source with voltage somewhere around 4 to 9 volts. It only need a brief boost, the higher
volt source needs shorter time obviously. For ~9v only probably need few seconds. I guess you could use 12v as well, but keep it short.
Then put back and try charging.
