Can Android OS cause charging malfunctions? - General Questions and Answers

Hi,
My phone suddenly won't charge the battery any longer unless I plug the cable into a Laptop/PC (USB). I bought a new battery, I tried 3 wall chargers, 3 cables and different mains sockets (all tested on different devices and all working).
I wonder if this problem could, in theory, be caused by the Android OS and not by the hardware. Does Android OS regulate the charging (not discharging or use) of the battery? Or is charging only a hardware function?
If the OS were to be involved, what would be the quickest way to fix such an issue?
FYI:
------------------------
Samsung SM-N9005 Note 3
4.4.2
Kernel 3.4.0-340325
Root on stock XXUENA2 ROM
------------------------
When I use wall chargers, while the device is OFF, the phone starts vibrating every 3 seconds until I disconnect the unit (but won't charge).
When I use wall chargers, while the device is ON, the charging red light and he symbol inside the battery icon appear (but won't charge) and will stay on even if I disconnect the unit.

i doubt its a software issue, if you want you could factory reset (remove all your files off your computer, there is a file transfer app in the play store if you cant get usb storage. or if you want you could odin factory reset, pretty much re installs the Stock OS otherwise i would try to get a new one.

I already did FR from device but nothing changed.
I can't do FR from Odin because the PC won't see the device ("USB device is not recognized") and I already deleted and reinstalled all the drivers twice plus, the third time, I installed Kies - nothing! Still can't connect.

Yep... BUT... Samsung won't recognize any warranty as the unit was purchsed online from HK www.imobilephonex.com (beware!)... so, any other idea before I go ahead and get a new one?
--------------------------------------
but... on a happy note, I just discovered that here, in Japan, American Express offers me 3 AMAZING FREE warranties:
1. Warranty plus (extends the original warranty by an extra 2 years regardless of original period);
2. Homeware protection (accidental damage, loss, theft, fire, flood, etc - up to 100% refund or replacement within 6 months, 90% within 1 year, 80% within second year, 70% 3rd year and so on);
3. Shopping protection (total replacement - no questions asked - within 90 days: damage, loss, theft, pretty much anything)!
WOOOOOOOOOOW! So it's my choice if I chose to have it repaired, replaced or refunded. Japan is an honest and amazing country... this would never work in Italy where I'm from!
Only 2 conditions/limitation: not valid for mobile phones (Note 3 considered "tablet" so ok) and I must show damaged unit (unless theft or loss in which case I must prove purchase).

Dead Tornado

So.. here goes my problem..
Got my Qtek 8310 three days ago, and the very same day I got it, decided to upgrade from WM5 to WM6. However, the battery charge meter gave me wrong info about the battery charge percentage, and the phone battery died just after I formatted the BINFS and re-setted the device in TeraTerm.
The device still powered on, after each USB cable re-insert, but died, after 5-10 seconds. After a couple of attempts, the phone didn't turn on at all.
Did some info search on the web and found out, that my battery fell to an critical voltage level. Li-Ion batteries require a certain voltage to even be able to accept a charge.
As I got an non-original battery (Sanyo ST26C) I suppose it is poorly designed and doesn't have good under-voltage protection (I have read about other HTC models (e.g. Wizard) having this problem as well), so the battery dropped below these limits and phone now identifies the battery faulty and doesn't let it charge. This is for consumer safety, because attempting to charge damaged Li-Ion cells can be dangerous, as Lithium is known to be able to catch fire/explode.
So the phone doesn't let to charge the battery in any way (1amp wall charger or USB cable).
Anyways, I tried to jump start the battery (charge with bare wires) to give it initial charge and... it worked. However, there goes my main problem: As soon as I insert the battery which has the initial charge, the phone starts immediately and boots to a bootloader (as there is no OS, formatted BINFS) and the the phone does not charge while in bootloader.
Then, I tried to turn off the phone: Hold down power off button for 5 seconds - phone turned off. But as soon, as I release the button, red light flashes once (as it does everytime, when you try to turn on the phone, it's normal) and then orange LED comes for a second, indicating a charge (as the battery is no longer considered faulty - phone lets it to charge), BUT then phone starts again to the bootloader and it somehow prevents further charge.
So: as soon as I release the power off button, after the phone has shutdown, it starts again, everytime, and soon the battery dies again.
My own thoughts of solving this:
* Get a fully charged battery from a friend, install the windows on the phone, and then charge my own battery (I know noone, who may have HTC Tornado, will be hard to get);
* Buy some standalone dock charger, which can charge batteries directly and charge the battery happily (haven't seen any around yet, so will be really pain in the arse, to get one);
* Charge battery with bare wires for an extended period of time, to give it enough juice to install windows (which I strongly doubt, as battery damage could occur);
Any other ideas? Ideas and comments, from people who know, or had similar experience is more than welcome. Looking forward for answers
Its funny. Reading you I've realized what people tell me about "I make a question and I answer it myself" So... You have the answers my friend. For options 1 and 2, use E-Bay. As a matter of fact, there is an aftermarket charger in ebay that charges your phone and a spare battery and it includes the spare battery when you buy the charger. I believe it runs for under $20.00. For option 3 use some wood cloth pins(those used to hang cloth to dry). I would say with at least 2hrs charge you should get a good 50% charge on your battery, enough to flash your phone.
Edit: Here is an Ebay Search. But, keep searching till you find the one that includes the extra battery. Chances are your battery is no good or won't last you very long.
Good Luck!
Get a new battery man, these li ion batteries, are no joke, especially the fact that they are made in China/Taiwan, I myself had used a tornado battery even till the days when the battery has bloated and cracked the back cover, when a single charge could not even last 4 hours.
Those days, were like having a timebomb in your pocket, ended up I got mysel a new tornado at a price cheaper than a replacement battery.

Well yes, I have some suggestions, but I am also expecting others to have some, too. And by sharing the knowledge, maybe I could prevent myself to spend more money on this issue

The main problem with e-bay is... my country. at least 80% of the items, don't ship to my location.

Thanks for the suggestion. The main reason why I am in serious doubt about this option, is that standard chargers usually have some sort of regulators and monitors the charge, prevents from overcharging, etc. But on the other side, USB charge output is only 100 mA, so it couldn't be that bad if you think about it

Well, the fact, that it is manufactured in China actually says nothing Many companies choose China to manufacture their products because of low costs. And the most of electronics is manufactured in China and other Asian countries.
Anyway, before getting myself an new battery, I would like to try resurrect this one If this won't last long for me - no problem, I will get an new one. But until I'm convinced enough, it's a waste of money, which I don't like doing
And one more thing.. maybe someone knows a way to keep the phone power off?
Because as I said earlier on, it's charging only when it's turned off, and not in the bootloader. And problem is that, as soon as I put the battery, it starts-up the bootloader.
Get a desktop charger perhaps?
Or if you are adventurous enough, mod the USB cable, and charge the battery directly, only if you know what you're doing, and only if it works

Well.. thanks for the answer, but we've already discussed this option and now I am asking whether or not, someone knows a way to turn off the phone and keep it turned off (prevent from self startup) while the phone has no OS (got formatted BINFS).

I've already done that, and yes, it works. But I need someone to confirm, if it is safe enough to charge the battery for an hour or two.
Have anyone tried that?
I don't think that it's very safe. But I was having a similar problem, and I just left the phone connected to the power cable, and even though it seemed like it was not charging, it apparantly was.
Or you could just get a new battery. On expansys I saw a new one for ~$20.

Well..
With a modified USB cable (bare wires), which got power output of 100mA I have charged battery directly for approximately 3 minutes, and the phone turned on, and was operational for 4-5 minutes until the battery died again.
And before that, I've tried leaving it on an mains charger, which got power output of 1A (1000mA, 10 times USB). I left it for a hour or two, although no led was showing up to indicate a charge. The phone didn't event turn on after this 2 hour "charge".
And the reason for this is explained in my first post. Will try to leave it charge over a night, though, expecting for a miracle

But new batteries usually come empty, so it's no use to me. I have also explained why, on my previous posts.
So before buying an cradle charger, I would like to find out if these budget-friendly solutions will work:
1) Find out how to keep the phone powered down (because it's the only moment, when it truly charges);
2) Find out if it is safe enough to charge battery with bare wires for extended period of time (1-2 hours);
Just came up with another idea. Searched the forums and found a very similar problem to mine:
fritzgerald said:
For some odd reason my wizard likes to say the battery is full when its actually dead and that it's dead when it's really full. Well a few days ago I was reflashing to try and take care of the issue and it died during the middle of flashing. It would only goto the bootloader screen and would not charge. Well I decided I'd post a few pictures of my recovery technique utilizing my wife's phone. Cat5 cable striped at the end and twisted to each of the positive and negative battery terminals and the Blackberry's battery put it so I could use it to power the wizard.

So.. I've got a Sony Ericsson w810i, would this technique work? The w810's battery is Li-Polymer, 900mAh 3.6V (although some sources say, that this exact battery is 3.7V..), compared to Li-Ion 1150mAh 3.7V Tornado's battery.
Voltage seems suitable..
Haven't got any answers to my previous posts, so I tried.
The trick worked, Sony ericsson's battery can feed HTC Tornado perfectly. However... got another problem..
Here's how I wired it up. The positive wire takes two contacts and the negative takes another two aswell. The ends of the wires are then connected to the sony ericsson's battery. Phone starts, and boots to a bootloader. Everything's seem to be perfect.
Then I plug in the USB cable into the computer, the other end to the phone. Phone recognizes the cable and puts label "USB" at the bottom of the screen.
However, there's something wrong with the connection.. TeraTerm fails to connect and Update ROM utility fails, too, with an "cannot connect" error..
After that, I have tried using the original battery, with no wires attached, just plugged it in (gave it an initial charge again) and the USB worked without any problems: TeraTerm can connect.
So the problem seems to be in wiring.
I have tried to connect the wires in different random ways (crazy, I know), but only one alternate way did worked. Although, phone did heat-up rapidly at the area, where it says "HTC Innovation" and phone's display showed "USB" even if no USB cable was connected.
So.. looking forward to some thoughts or any knowledge, of why is this happening, wiring schemes, or any other suggestions..
FINALLY! SUCCESS!! I've connected the wires from the sony ericsson's battery to touch only one pin on the phone, instead of two, as shown in the picture. The phone didn't turn on, as I've tried this before.
But then remembered that the same pins charge the original battery, so inserted the battery and VOILA! Phone turned on to the bootloader and the USB circuit wasn't blocked no more! Flashed the phone to WM6.5 now successfully and the original battery is charging, as I write this post )
So, if anyone got HTC smartphone dead, while flashing, let me know, will try to help you out, since I've walked through this hell myself

1A Wall Charger Works!!
I've had the same problem discussed above. I was trying some of my own 6.5 ROMs, which by the way were getting stuck at the initial boot screen itself. Due to some unavoidable reasons and circumstances, the phone freely was left to itself at this exact state, untethered to any power source, for extended periods of time, during which it slept and refused to wake up again, all my pleadings going in vain. And when it did boot, it went into the tricolor screen conveniently and switched off in ten seconds. I turned to the net for help and found that any charger with rating above 1A would help in giving it the required juice. I didn't want to waste any of the 6 USB cables I have.
I got the original charger, which is an 1A charger, after 2-3 hours of searching my room (Hey, Don't be too hard on me! In the end, I got it, right? Actually, I use the PC for charging, and a smaller 550mA one sometimes-- both didn't work this time) and then, when I connected it showed the screen again. But this time, I found that it was capable of running it without the battery being present.
So, all I did was I kept the charger connected to it with the phone switched on in the tricolor mode and with the battery inside. After half an hour, I tethered it to the PC and flashed a proper ROM. And Voila!!! IT WORKED!! It was 2.45 in the morning!!
I guess the power from the 1A charger is enough for the phone to run and charge it too which is not the case in the 550mA one and the USB cable.

Glad to hear that it worked for you Unfortunately, it didn't for me (as I only have an after-market charget, not the OEM one, although it is 1A), so I had to search for alternative methods.

Can't charge after updating to JB

Hello,
This is the first time I am using Android so please understand that I know basically nothing about it.
So I received a refurbished note 10.1 (software 4.0.4) with about 50% of battery left. I played with it like 3 hours and then updated to 4.1.1 (or 4.1.2), battery went down to like 10% so I plugged the charger in and kept playing. After further 30mins I realised my battery still goes down (8%). I had a quick look in Google and many people are saying that after updating to JB tablet takes very long time to charge or doesn't charge at all. I thought mine will charge slowly so I left it overnight plugged in. I woke up with 7%...
I tried charging it with a USB cable connected to a TV, in the first hour it charged to 8 and after that (about 3h) it stayed the same.
So the question is: Is it the charger, software or is it just a faulty tablet?
What I would like to try is to downgrade it back to 4.0.4 but I am not sure how to do that (or if it is safe) with such low battery level. Is it possible to downgrade when tablet is off?
Thank you

Factory reset or reflash the firmware JB you flashed .
But i would return to the seller has you have no evidence JB is the problem as you only had the tablet 3 hours .
Flash any firmware via Odin min requirements 30% battery to be safe .

Have you tried charging from an actual power outlet I don't believe that you can charge them via tv, pc or any other device only via an actual power outlet.
As far as roling it back to ics I believe you would have to flash it but don't take my advice on that one, maybe someone else could advise?
Also no I would upgrade or down grade firmware without a fully charged battery.
I found that mine was charging worse after jb update I actually factory reset it and its a tiny bit better, I still find though that if I want to charge it fast its best to turn it off and let it charge, I also noticed that the biggest culprit for draining the battery atleast on my device is Skype just having it running in the background drains it heaps.

I left it charging the whole night using the included charger (It looks like an original one) and as I said it only dropped by 1% (tablet was off the whole process)
From what I know it does charge through TV's and stuff but it just is a lot slower.
And I have no apps running, wifi off, gps off - everything off. RAM cleared
// After about 3 hours of charging through a TV it went up by 1%...
I left it charging through a TV because if a normal AC didn't help I thought it may be something to do with the charger.

Factory reset is in settings under personal heading its the backup/reset tab obviously make sure you back up your stuff first or you will loose it, this won't role it back to ics but might help. Also I have never found that any of my android devices charge via another Device only wall outlet they do maintain the power level there at but don't really charge.
Do you have another ac adapter I youncould use to test with try a different ac adapter if possible.
charging cable likely cause
I have had very bad luck with factor Samsung cables.. I would Use a different usb cable and wall plug usb brick.. make sure its output is equal to or above the original Samsung charger .
This is likely why the device was returned to begin with. As most of us know refurb devices are usually just open box customer returns. Often are just factory reset and resold .

It might work check the voltage to see if its the same and use your usb cable, they use mini usb I believe. Thats the other thing the usb cable that you using might be stuffed. The cable on galaxy tab 7 looks 100% but it doesnt work at all, as erica_renee said samsung chargers aren't the greatest.
I use a Belkin charger much stronger than samsung original
From what I've read, one review says that there is no way to use a S3 charger. + it has 1A
Apparently note uses different pin configurations..
I have no idea what to do now... :<
What about finding a galaxy tab charger?

Right, before I get one, at the moment Im trying to use iPhone charger with the standard samsung cable. I showed a red cross (what I would expect it to show). I then tried to hold the volume up while plugging it in (Ive read on one forum that it helps, not sure what it does but worth trying) and it jumped up by 1% - no red cross now... I have no idea what Im doing or why no red cross is visible.. ehh
//edit:
Guys.. this is working!
Another 1% in 15 mins.. It may not be much but believe me, Ive been waiting for that 1% for a long time
I'll give an update soon
//
Further 15-20 mins and it increased by 2%. Well, yay! I guess

Hi all,
last night my n8000 stop charging. ..
I even tried the different chargers and also tried to charge thru pc...
When I connect with charger the beep sound come but nothing more and cross sign appears on battery icon.. and worst of all my n8000 not even recognized by pc even...
Any idea ?
EDIT : changed the cable and everything returns to normal
Yes, return under warranty... This is not right. It sounds like the usb connector might have a problem...

Charging problem on stock ROM?

Hello,
My wife and I both have a Nexus S, which are both almost 2 years old now. She has always been running stock ROMs and only updated when there was an OTA update available. No rooting, no nothing I however tried as much as possible and currently running SlimBean 4.2.2 Build 5 :good:
Since 3 days now, the battery in my wife’s phone isn’t charging anymore. I tried the following:
- Use my charger and an old Nokia charger: doesn’t work
- Put my battery in her phone: doesn’t work
- Put her battery in my phone and charge mine: works like a charm
The last one’s the solution for now: at night I charge one of the batteries in my phone and put it in hers, while at work I charge the other battery from my PC via USB.
Based on my ideas I’d say that something in the USB-port on my wife’s phone might be broken. However, there are 2 phenomena that I find rather strange:
- When her phone says it’s time to connect the charger, I take out the battery and put it in my own phone. I power up and the battery level reads somewhere between 60 and 80 percent
- When I power off her phone and connect the charger, I’d expect to see either the charging symbol or nothing. But none of these: it powers up as soon as I connect the charger
I don’t know about the first issue, but could it be the battery stats might be corrupted? The last issue makes me believe that the USB-port is at least not completely disconnected/broken.
Has anyone got an idea what the issue could be? I wouldn’t want to work on her phone rooting it if it isn’t necessary, but on the other hand she might be better off in various other ways as well
Thanks in advance,
Pieter

Being completely stock and never modified, I'd say it's the usb.. Have you tried the OEM connector for the computer?..
1. I would take it to a shop
2. You could also try cleaning the contacts
3. May do nothing but if you take the battery/sim out and hold the power button for a minute, this is supposed to completely power down the phone, and then reinstall sim/battery and reboot..
4. Use this as an excuse to modify her phone (telling her that you can put it back to stock if she doesn't like it)..
This happens a lot on my phone, .. Be careful with my solution, I hope it works for you..
Basically inside the usb port on the phone, there is a flat pin. On my phone, this pin ends up bending downwards towards the bottom of the phone.. What you could do is get a very thin knife or a swiss army blade and just try and lift the flat pin in order to make it locate in the center of the usb port (hole) .. The issue being the pin doesnt connect with the charger ..
I hope you understood this
PS: Don't snap it !

New problem with Note 5?

Back story: Immaculantly cared for Note 5, in case since purchase, no liquid damage or premature USB port ware. I use the wireless charging pad exclusively. Charging cable is in mint condition and even tried additional spare Samsung cords/blocks to troubleshoot with same result.
Problem: Note 5 having seizures when it's plugged in or charging wirelessly. Every time.
Witnessed activity: Constant cycling through charge/not charging states, red icon over battery, power sharing activated, Gear VR being activated without my input. Constant cycling vibrations, lag, and loss of touch input (maybe due to lag).
Troubleshooting: Multiple cords/Blocks (Factory OEM), battery diagnostic shows ok, able to transfer data without issue via cord as long as its not charging, Hard reboots and a cache wipe (4 seems to kill the activity), Verizon Tech Coach can't figure it out and then promptly hung up on me bc it was closing time.
After workaround phone performs at optimal until charge is required.
This will be my 3 warranted phone in 3 months if I cant figure this out.
Solution: ?????????????????? Help. Please
Sincerely,
One unhappy Note 5 customer

You might have to warranty the phone again. I was going to mention start over from scratch and wipe your phone. Which firmware version are you? Im on the default 5.1.1 OGJ firmware.

Samsung Galaxy S6 is telling me it is overheating, it is cold. How Backup?

Dear Androidpeople,
Since November, I am the glad owner of the Samsung Galaxy S6. I am a really Samsung fan, I have had the S2, S3, S4 and now the S6. The previous two weeks I had some charging issues. In particular, sometimes I had to plug in the cable three times before it really 'connected' and started charging. I tried it after that with another Samsung cable and this problem was solved. The day before yesterday I was planning to charge my phone and when I attached the cable to the phone it only started to charge after the phone was already 10 minutes connected.
Till this issues I didn't see that much problems. Every morning my phone was with al my problems, fully charged. Since yesterday, the big problem started. My phone was complete dead/0% battery. I wanted to charge my phone and I got this error: (I got the error in Dutch and tried to translate it, as best as I could)
Cannot charge phone
"The device is stopped charging. De battery temperature is too high. Be careful with disconnecting your charger. It could be very hot."
"When you disconnect the charger and reconnect is afterwards, you could possibly proceed charging your phone. If this overheating issue keeps existing, please contact our customer service because of risk of fire and injuries."

I have never had a problem of this kind. My phone and charger were both fully cold. I spoke with a guy at Vodafone and he told me this should be a case of warranty of Samsung/Vodafone. The problem now is, back-up.
The device is 0% charged, I could not charge it anymore and when I turned my phone on, it directly turned off. Now did I try to charge it yesterday and last night with multiple chargers. This morning it suddenly was 13% charged. So i quickly ran to my laptop to connect my device with it and start back-upping photos. But after connecting it tries to charge and I get the same error as i mentioned above. If I just look on the device itself every app is blocked for 'safety reasons' except 'Phone' and 'Contacts'. I cannot look into the Gallery, Dropbox or Onedrive. The device connecting with the laptop was not helpful. The laptop does not recognize any phone connected to it. So copying files from the laptop and the phone are not working. It looks the end of the possible solutions but maybe I forgot something.
Things tried tot fix it:
- Three different chargers
- Two different laptops
- Two different data cables
- Connecting via power, via laptop via the power bank.
- Cleared Dalvik Cache.
When I let him pick up by Vodafone they will try to fix the issue, but I will lose every photo from it. I know I should make a backup earlier. But that is talking now. Is there maybe one solution, one clever thing, one special tweak I could do to save my photo? Or should I start my grieving process?
