[Q] charging issues, charges extremely long, stops charging randomly

Hey I was wondering if something is wrong with my device.
I am encountering weird things regarding recharging the device in reliability charging up.
So i am using the original charger which came with the phone, the phone is just like 3 month old i didnt notice anything like that earlier.
So when i am charging the device, sometimes it stops charging, Today I encountered it charging to like 56% and afterwards no more charging so when i got up, my phone was 14% left even when plugged in.
I encountered it several times recently that it stuck recharging at around 50-ish or 70-ish %.
charging usually takes up reasonably long. About 10% an hour. In Settings -> Battery it sometimes it displays USB even when it's charging via AC.
I am not running any fancy apps which drain the phone or clock cpu.
I am running 4.1.2 I9305XXBLL3 Rooted.
Anyone have any suggestion?

Samsung charger that come with the box really charge slow because it only supplies 1Amp.
But for your case seems different. Before checking the software side... have you checked if it's the charger or the cable itself has the problem? Try using other charger.

do you think a nexus 7 charger works fine w/o doing any (more) damage?

Many times it's because of dust and dirt collecting inside usb port. Clean it with compressed air or small brush and try again.

i am aware that dirt might be the problem, but i've took my torch and put some light into the dark usb port to see if there's any dirt but everything looked quite clean to me. I don't have compressed air with me atm do you think a manual air blower used to clean dslr sensors can also do the job?
any other suggestions if the charger and usb port ( dirty ) is not the case?

Use toothbrush and tiny bit of alcohol ( can be after shave) on it to clean port. Do it when phone it's switched off. It's worth to try.
Did you try different charger?? This can be main problem. Many faulty chargers this days.....

i have been trying out the nexus 7 charger. it seems to be a bit faster but not as fast as i am used to be on galaxy s2 ... i used the air blower and a tiny bit of dust came out but not quite much, i will see how it performs.

Check the output voltage if same, a bit higher ampere would be fine just not too high, and not voltage.

Samsung charger provides 1000mah because that's the stock charging setting for the SGS3. You'd only need a different charger, like a N7 one if you change the settings to above 1000mah.
OP use current widget to see what current your phone is charging at. It should be 999mah from the wall charger, then you can change chargers and see whether it's the charger or your phone with the problem.

[Q] Plugging in charger has no/almost no effect on current flowing through battery

I'm having a problem charging my _new_ Nexus One. In two words - doesn't charge. Tried two batteries and two wall chargers + USB; same result - it charges VERY slowly when the phone is off - like, 1% per hour, and not-fast-enough-to-stay-alive when the phone is on.
So I've been googling for quite a while today, read several dozen threads and it seems that the issue is rather popular. However, there are a few problems:
a) No solution was advised
b) The ones advised didn't work
I've read that I'd better measure the current that's going through my battery and if it's too small, then I have a problem. I've installed an app - Battery Monitor Widget it's called, I think, and saw what's happening. I didn't know what they meant by "small" current, but my case was easy: the current is NEGATIVE even when "charging". In fact, the app doesn't see the difference between an unplugged current and plugged current. This isn't the problem with the app - reversing mA only helps with the app, but all other applications also show that the batter is draining. Note that the LED is ON, that is, the device does detect that the charger is plugged in, it even heats up like usually (I've had nexus one before).
So I thought that was a software problem with 2.3.6 kernel, so I've sacrificed my warranty (the seller p***ed me off - even if the phone turns out to be defective, I'm not bothering to send it back). I've installed Cyanogenmod 7.1 - kernel 2.3.7, but the problem persists.
So I really have no idea what may be causing this or what the fix might be.
Any ideas?

charging very slow!

help,my note now charges very slow 4-5hrs without using.
it depletes if im using it while charging.
could change rom,kernel be a fix?
thanks

Heading for a new battery me thinks.

Are you using your stock charger? If not, how many A does your charger have?

i just bought an extra battery.lets see how it goes.
i noticed my old battery had a small bump in the middle seems bloated. hmm
i remembered last time i used xperia s charger trice,it has 1.5kA it realy charge fast. i think that caused the problem?
when my sister charge her xperia s, the charger just explode.. and she scolded me why am i using her charger.
im using my old charger which is 700ma but it charge just fine. lately when i use the xperia s charger and went back to my old one,it was acting strange. it charges really slow and if i use the phone,it depletes even when charging.
im going to flash another rom,and see if its rom related or the battery isue.
thanks for replying.

ok,im on with my new battery but still depletes while im using it. im just browsing. on the widget it say im currently charging with 1000ma. wierd, dont know how to solve this.

[SYMPTOMS I HAD] it would charge very slowly, if the screen is on, it would actually discharge. When the phone was off, it would slowly charge (i.e. >5 hours to full charge). and it would discharge very quickly (i.e. 1% per 2~3 mins). When the phone was off, it would charge sometimes and sometimes not. Figured that when the phone was off, you really are negating much of the software influences so this could be a hardware issue, however, wanted to make sure before going down the hardware route.
Did some research, searched the forums and searched some more.
I had tried 5 different chargers, 3 different USB cables and had bought a replacement battery.
Steps taken:
1. Cleaned with thick paper - no change
2. Cleaned with thick paper & rubbing alcohol - no change
3. Cleared with Compressed gas - no change (on first charge, there was a change but then back to normal)
4. Attempted to clean with vacuum (with finer nozzle) - no change
5. Used charging apps from playstore - didn't show charging details - considered the port was faulty
6. Tried to find default references for charging as mentioned in one of the forums - unable to find it
7. Found a replacement USB port charger board and replaced it - working fine
So it could be the actual port is faulty. If you symptoms match, it could be time to take it into the service centre, restoring to stock first of course. The note I am using had slow charging for about 2 months prior to really slow charging.

i had change the usb port and its back to normal. 2hrs at least and its full.

Fingers crossed, thats all you need.

[Q] Battery drain while using the phone connected to wall charger

Hi all, I have never experienced this kind of wierd issue with any of my past phones. When i would play games or say watch a movie on phone,( my last one was Htc One X), i would usually connect it to a charger so that the battery keeps charging slowly, and it worked with each of my past and even my gf's galaxy s4. But with XZ, the battery keeps continuously discharging. Anyone got any fix for this? With the kind of weak battery XZ has, it is a highly needed basic feature. I even tried with a 2A S4 charger, but to no effect. I even tried the modding of usb cable by shorting the data wires (the green and the white wire cut and insulated), still no improvement.
I have been using existenz v1.5.5 kk, and i can see that there is an option of fast charge in performance control. But turning it on doesnt make any change. Does the kernel not support fast-charge?Can anyone share any insights? It feels stupid to have to lay the phone down letting it to charge by itself olny to get all discharged within 3 hours.

Charging is really a problem for XZ. Anyways, shorting the data wires won't help, try switch to a stronger cable that's capable of transferring larger amount of electricity when you're using the 2A charger (many of those cables aren't able to transfer enough amount of electricity).
Also, when your phone is really fully loaded and became very hot, just as when you use it for navigation in your car under the sun, the charging speed will decrease (I don't even know why). The charging speed decreases either when you're touching the screen or when it's hot.
Anyways, try better cables first and see if it helps. The docking system is also likely to charge faster.

I used a whole bunch of cables. The HTC one actually works as an anti-charge cable lol, it eats up battery even when the phone is left on charge unused. I had high hopes with the S4 cable, which turned out to perform same as the stock Sony one. Guess I have to live like this..

Sorry to hear that the cables you tried all failed. Did you try using the docking system? They should perform better though.
I mentioned switching cables because I had a "anti-charge" cable before, lol. I did some research afterwards and finally got some 22AWG cables and they really made a difference. It's said that they're capable of transferring 3A electricity and it's really different from all other cables I've used. They're just about $2 each because they're handmade, I can give you one if you wanna have a try.
Also, charging by AC power should be better than using the power of cars' lighter. I'm using my docking system with the SONY stock charger w/ ac power. Never disappointed me.

Dude you might not be able to give me even if you wanted to.. I am in india and the shipment cost will be excessive. Thanks a lot btw.
I flashed Carbon KK rom and the charging is comparatively better. Atleast it doesnt drain while i use the phone for browsing etc, connected to a wall charger. But if I play games or watch videos on speaker, it does to some extent. I bought one more charger, a Nokia made 750 maH charger (AC 20N) which again is wierdly same in performance compared to both the 1.5A Sony and 2A Samsung. What I think is as you said, the wire makes all the difference. A 2A non detachable is the need of the moment for XZ it seems..

Anti-charge cable?
Xperia™ Z (C6602) with Tapatalk

From my experience usually Google Play Services is the culprit for hot phones and battery drain. What I did when on stock 4.4.2 was i uninstalled updates for the services and my battery life improved by a lot. Although it does come with the downside that some apps like youtube won't work with the older version (easy work-around by using chrome to go to youtube instead =P)

Since I own that phone, I've been facing the same problem of slow charging speed (actually discharging when using some applications)
The more problematic case in when I'm using the phone in car when driving even if I'm using a powerful car charger (Anker).
In the past I also have tested number of diffferent charger and cables (including original Sony car charger) without seeing *any* improvement.
Recently I've decided to took time to make a comparison test with a colleague Nexus 5. We have connected it in my car to the same charger and used in the exact same configuration (Waze navigation app running) for a one hour drive on the same work->home daily path where I use usually my Xperia.
The measured results have shown for the Nexus a 30%/hour increase of battery level opposed to the Xperia 10%/hour decrease I'm facing every other day.
Later, using "Android tuner" application battery monitoring tools, I've been able to measure that, even when using a 2.2 Amp capable charger, the Xperia isn't able to "suck" more that 700/800mAmp input current most of the time.
To go further I've asked in the french forum where I've posted those figures if any people had been successful to have the Xperia battery level increasing in the same configuration. I have got only answers of other people acknowledging having the same problem as myself.
Then I've also asked people in the "accessories" section of a car owners (Toyota) vehicle forum: found people having the same issue are also owning Sony models.
Also asked another colleague who who owns a Xperia model Z1: ditto.
I definitively start to think that there is a defect is a in the battery charging regulation system of the whole Xperia range.
BTW: I will be very interested if anyone using an Xperia Z in car with navigation application running without those issues could post details about his charger brand and model, and how much battery percent/hour increase he his actually getting with that setup.
Sorry for the long message and thanks for your attention

Battery 100% On, 80% Off

phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted

l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery

Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

I tried - original cable with original charger 6hr
- original cable with apple charger 2hr
- different cable with original charger 1.30hr
- different cable with apple charger 2hr
(Used different fast chargers too, same results)
I tried a smart switch recovery. Same conclusion which makes me think its a hardware issue

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped

Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.

I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)

I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?

So... any solutions?
