[Q] SGS3 i9300 Not Chaging - REWARD - Android Q&A, Help & Troubleshooting

Hi guys I hope you can help.
I AM OFFERING A REWARD OF £10 GBP TO THE FIRST PERSON WHO SUCCESSFULLY ADVISES OF THE RIGHT FIX FOR THIS ISSUE *.​
There, now I have your attention - brace yourself, this one’s a tough one.
About 2 months ago, I flashed DeltaROM 4.2.2 V2.2. I’m a serial flasher so I’m quite aware of what I’m doing. I had some issues with it that I tried to get support from them but they unfortunately didn't get back to/couldn't help me.
The original post is here in case you’re interested, the biggest issue being my S3 no longer charges correctly. If I plug a charger in from the mains, it will not register as charging. Once every 10 seconds or so, it will actually register the charger, but only for about half a second before it drops. It DOES however charge if I connect it to PC, Xbox or car (only wrks in the car if charging from a USB socket, using the in-car charger straight from the cigarette lighter doesn’t work). Basically, I can charge my phone off anything that isn’t directly the Mains electricity.
I’ve googled the hell out of this problem, only to find that posters will quickly dismiss it as faulty hardware; bad USB cable, broken USB port, bad charger, low voltage from mains – anything at all. But the bottom line is I do not have faulty hardware. Everything was absolutely fine until the very instant I finished flashing DeltaROM – I’m convinced something didn’t go right during my first installation since it was a bit rocky (read the original post for details).
After getting no answer from the Delta lot I jumped ship to LiquidSmooth (which is very nice by the way) but the problem remained. In one last attempt I started again from scratch. I used TriangleAway, formatted EVERYTHING (the kind that also deletes all your media) and flashed back to stock. Using Samsung Kies I 'upgraded' the firmware and I'm now on the latest official 4.1.2 release – and it makes me a little sad!
Just to back up the fact it’s not hardware related, I deliberately persevered with it to gather up as much information as I could, and here’s what I learned:
Why I'm sure it’s not the battery.
• I've tried two other batteries (3 total) and the problem exists with all 3
• The health of my battery is excellent
• My battery charges fine in other phones
Why I’m certain it’s not the Charger
• One of my chargers is only a couple of months old
• The charger I have been using is the official Samsung one that came with the phone, though I have 3 more – one BlackBerry one, a charger that came with my s1 (many moons ago) and two the same that came with mine and my gf’s phone. These are the plugs with a USB input on them,
• I have 5 chargers in all – BlackBerry, Nokia, Samsung (x3) ALL of which don’t work with my phone but ALL of which work with EVERY other phone in the house.
Why I’m sure it’s not the wall Socket.
• I’ve tried every plug socket in the house and even taken it to my parents and to work – same story.
• Everything else I plug into the sockets work just fine
Why it’s not a bad USB cable.
• I have 3 that I use. All of them will charge off of the computer, the car or the Xbox – they cease to work when I use them in the mains USB plug.
• They all work fine on every other phone in the house, regardless of if it’s in a mains adapter or a computer
• I am able to connect with all 3 cables to my laptop to view files.
Why I don’t think it’s a damaged USB port on the phone.
• It ‘does’ actually do everything it needs to do when plugged into my pc, Xbox or car. If it’s communicating well with other devices and harbours electricity correctly when doings so, then it can’t be the USB port since the way it gathers energy is the same.
So what gives? How can it be bat hardware if it works from the PC? How can it be bad firmware when I am back to Stock?
Thanks a million guys.
* Telling me to send it off for repair doesn't count. If it's something that I can do at home and it fixes my issue, the first person who gave that advice will be the winner. This does of course mean that if my phone is just downright screwed, there's a chance no-onw will win.

Have you tried to use a kernal like siyah kernal and change the chrging parameters for ac charging? (the Mah value for charging off wall socket...

Hi Koogly
Sorry probably should have mentioned this. I tried siyah and set everything to charge as much as it could - AC and USB. I also tried a lot of other 'fast charge' apps to no avail.
While the USB does charge, it's still quite slow at 460mA. Once in a while, the mains charge stays connected, and you can watch the mA level drop. It will start at around 999, but within 10 seconcd it will decrease down to 100mA, which is slower than the phone actually uses up energy.

Nobody?

Batteries

I had a quick look but i couldnt find these ones on the site. As most of you know a spare battery (or 7) is a must with the TP2. But im a noob and im not sure what the difference is with these with the mAh ratings. Is there much difference between 13050mAh and 1500mAh batteries? which will be better?
Heres the 1500mAh battery
Here is the 1350mAh battery
Thanks
Personally, I wouldn't get a replacement battery from HK, and not over Ebay either - I've used one source for two-way radio kit over there for a while, and while the Li-Po and Li-Io batteries do work, they appear to have a limited life span in comparison with OEM equipment available over here.
I'd think about long-term savings, and get something from Clove (linkage here), who at least can be held accountable to the "fit for use" elements of the Sale Of Goods Act 1964 over here, unlike HK sources via ebay. Don't get me wrong - ebay's a great source of bargain kit, but for something as essential and spec-critical as a PDA/Phone battery, I'd go home-grown retail sources every time, purely for the legal protection.
In any case, I'm getting a PowerMonkey from Maplin today. Much more versatile for me
My spare batteries have always been HK cheapo's and never a problem with them before. If that one you showed me was half the price it is then id have got it.
1600 mAh battery from the uk?
Is this really genuine?
SMF_12 - I opted for the powerMonkey for a number of reasons.
It's small enough to lug around in a pocket or belt pouch.
It carries potentially two full TP2 charges from a single full charge
It's got a long shelf life on a single charge
It's got adaptors in the box for most of the portable devices you might already own that take a 4.5-5.5 vDC charge
If by chance your connecter isn't there, they suply additional ones at a very reasonable cost
It'll charge my TP2 and my other half's Razr (that's the motorola phone, not the ladyshave ) too
Oh, did I mention it's rechargeable off anything with a USB port, and can take a charge off any mains power socket on the globe (travel plugs come as standard).
I'm rather impressed with it
However, if all you want is the spare battery, then by all means, go for that instead
As to the "is this genuine"... he's in the UK, subject to the Sale of Goods Act and the Trade Descriptions Act. If he's telling fibs, he can be held accountable. Hope that helps
Have fun
UPDATE: Hold fire on the PowerMoneky, folks. There's a glitch. While the supplied USB charging cable works with the miniUSB adaptor tip to charge the TP2, the PowerMoneky itself does not - say again not - appear to be charging the TP2. Only found this out last night - I've been using the USB adaptor cable and tip up to now.
A trouble ticket email has been sent to them, asking for any information regarding this, and hopefully a fix as well.
You can imagine how damned annoyed - and embarrassed - I am at this point in time.
Update - very rapid response from PowerTraveller tech support - seems that they believe I need a "DOPOD" adaptor tip, and requested my snail mail address so that they could send me one - still doesn't explain how the miniUSB tip works when I'm using it in the car from the cigar lighter -> USB adaptor, but there y'go. Soon as the DOPOD tip arrives, I'll test it out, and update you all
Thanks for that, i took a look at it in maplins today but i think ill stick to a second battery. but im sure people will be happy to read your review on the product so keep us updated on this product
Will do
OK, DOPOD adaotor tip arrived today.
Result: FAIL.
The text of the follow-up note to PowerTraveller Customer Services, sent this evening, is reproduced below, less the name of the Customer Services agent there.
Thanks for the DOPOD adaptor tip, which arrived today.
Unfortunately, it does not appear to solve the problem.
I connected the tip to the PowerMonkey Classic lead, and then plugged it into the ExtUSB connector socket on the HTC Touch Pro 2. I then moved the switch on the PowerMonkey Classic to "on". Again, the green light on the PowerMonkey Classic started to flash, but there was no noticable difference from using the normal USB adaptor tip; i.e., there was no amber charging light illuminated on the Touch Pro 2, and no charging icon was to be seen on the screen. I have to assume that there was therefore no charging current making it to my HTC Touch Pro 2.
The entire point of purchasing the PowerMonkey Classic was the be able to recharge my HTC Touch Pro 2 when I was away from other power sources, such as my home, my car, and other USB sources such as notebook PCs, when out and about conducting, for example, GPS-related activities, which are heavy on battery consumption. The advertising that I saw led me to believe that the PowerMonkey Classic *would* be the solution to my problem. Sadly, however, despite your attempt with the DOPOD adaptor tip, this does NOT appear to be the case, and I am VERY disappointed, as you can imagine.
It is remotely possible that your engineers have missed that on the Touch Pro 2, the connector on the bottom of the unit is NOT a standard USB connector, but HTCs proprietary ExtUSB format (which combines power, audio, and data feeds in one socket/plug format)?
Could you possibly check with the engineers, and ascertain if they have actually physically *tested* the DOPOD with the HTC Touch Pro 2, and, if so, how they managed to get the darn thing to accept charging current from the PowerMonkey Classic?
As it stands now, failing a working solution from your selves, I am the poud owner of the thirty quid high-tech paperweight, that is of zero use to me. I am due to see my partner (who lives 70-odd miles from me) soon, and we will test at that time whether the device works in charging a Motorola Razr.
If it does, then, short a working solution for my Touch Pro 2 being forthcoming from your company, I will give my partner the device. At least then, someone will profit from using the device. I however, will be back to square one, searching for an on-foot recharging solution for my phone.
Finaly, I would remind you that all the above fails to explain why I can get a ten quid self-reeling cigar lighter adaptor unit in my car, using what appears to be a standard USB connector, to successfully charge my Touch Pro 2. Naturally, I would be VERY interested in knowing why this succeeds, where the PowerMonkey Classic fails.
Sincerely,
Roger Stenning

As you can imagine, I am far from amused at this entire sorry bloody saga.
As always, I'll keep you all updated, should there be anything to report.
EDIT:
Almost forgot - confirmation USB source test result:
Almost forgot. I checked to see if the DOPOD tip worked with a purely USB-derived power source, so plugged the supplied self-reeling PowerMonkey adaptor cable into the tip, then into my computers' USB port, and connected the tip to the Touch pro 2. Surprise surprise, the amber light on the phone illuminated, and charging current was flowing into the Touch Pro 2.
The problem is therefore sqarely defined as being with the PowerMonkey itself, and NOT the adaptor tip.
Casting back to my original note, I have to assume that the PowerMonkey is NOT delivering a powerful enough charge, at 4.5 VDC, where USB specs clearly require 5 VDC. There is therefore a deficit of 0.5 VDC from the PowerMonkey Classic.
I will still check to see if this is successful in charging a Motorola RAZR or not, and will report back to you at that time.
Sincerely,
Roger Stenning

Hope so, I've just ordered
Update time.
PowerTraveller, manufacture of the Power Monkey Classic v1, have sent me a returns form in the email, and have told me that once I've returned it, they'll send a replacement after testing.
Looks like the postage is down to me, though
Roger, if it's any consolation, I've had to do the merry dance that you appear to be doing right now. I bought a v1 just over six months ago and went through the exact process you have described. Just the other day, I received a replacement unit that I'm testing now. My problem was that when my phone was 'next to' empty, I'd plug in the v1 and it would charge to about 50% before itself becoming empty. I know the v1 was full because I had charged it for hours and the LED was green. "Two fulls charges"? Pfffft.
I also got the load of old cobblers from Powermonkey about the USB tips too. How I should use a DOPOD tip instead of a USB one. When I questioned 'why?' I received a half mumbled reply about the tips being internally wired differently. The one that they promised to mail me never arrived so I bought one from the website, being only like £3. Did it make a difference? No.
I don't know how this replacement's going to work out but I have my doubts. Before buying the v1, I bought two other Powertraveller products, the Powerchimp device that runs off two rechargeable AA batteries. I gave up on both of them within a week because even with two fully charged AAs, it seemed to charge my phone for about 30 minutes before being in an empty state and when I looked at my phone (TytnII) it had maybe gained 10% charge. OK if you want to make say one emergency phonecall but useless if you need the equivelent of a fully charged spare battery (or two!!!).
I'm going to monitor how it works out and see if this replacement works and provides at least a full charge and a half. If it doesn't, well, although it'll work on some level, it just doesn't do what it's advertised to do which is very naughty (especially when you see them laud their product all over the internet/Twitter etc as the most amzing thing since bread that has been sliced
One day guys, once day I hope the world will see a truly reliable and consistant portable power supply. Maybe in a thousand years, even a reliable solar powered products?
hiya - thanks for the heads up. It's be damned nice to see a curcuit diagram of the thing, along with a specific list of components. They try that mumbling stuff with me, they may bite themselves somewhere embarrassing - I'm also a licenced Radio ham in the UK (G1LIW), and as some of you might know, we have to pass tests in the technical aspects of the radio hobby - which includes electronics
I'm damned if I know what the preventative difference between a DOPOD and a miniUSB tip, either, by the way, given that the ExtUSB used by HTC only adds maybe 7 contacts to the format while avoiding existing MiniUSB pin locations...
MiniUSB layout...
http://pinouts.ru/Slots/USB_pinout.shtml
ExtUSB layout...
http://pinouts.ru/PDA/htc_extusb_headset_pinout.shtml
The two are not, of course, interchangeable - while MiniUSB plugs will fit into ExtUSB sockets, the reverse is not true.
Anyhow, we will see.
Thanks again for the heads up
Quick test result update.
I let my TytnII (battery, 1350mAh?) drop to 30% battery and then plugged in my fully charged P M Classic. It charged back to 100% and the charge LED was still flashing green. I then plugged in my half empty old Motorola V3, it charged it for approx 30 minutes before flashing red and eventually stopping. 2200mAh!?!? capacity? I bet I didn't consume any more than about a 1000mAh and it was empty.
OK, it's new so this might go up a bit but it really doesn't bode well. OK, so maybe I'll get one full charge out of it but it's advertised as 2200 my phone is 1350, surely it should be up towards about two charges?
Bottom line is, it works but nowhere near as well as it's advertised to do.
OK, received the replacement PM (it's a version 2, not a version 1) in the mail today. They included another DOPOD adaptor tip, too. Guess they figured I'm a clumsy schmuk who may have lost the one they sent me the other week (nope, still got it)
Anyhow, Turning it on results in rapid green LED blinking, meaning they fully charged it before sending it to me. Which was nice of them
However, and interestingly, plugging in a charger to it does NOT result in any LED illuminating. Odd. have to follow that up later.
I'll let you all know how it behaves in charging my phone once I use it "in anger".
Be interested to see what you make of it's charge capacity...
Cured the inability to charge the PowerMonkey problem - it was a rather embarrassing user error - the plug wasn't correctly seated in the mains socket
Gonna let the phone drain a bit while I'm on holiday this week, and use the PM to charge it. It's a PMv2, not a PMv1, that they sent as a replacement, remember, so we will see if the thing behaves any better than your v1
Later
After a month or so of tests, I can say my version 2 is 'better' but it still doesn't delivery the one and a half charges it's supposed to. On average, I'd say it fully charges my TYTN2 once and is then empty.
I really can't be bothered to stress about it any more because I guess, one full charge is better than nothing but I think I'm justified in being a little irked that it doesn't do what it's advertised to do?
Conclusion: It works, it'll charge your phone to full from empty and is an alternative to buying a spare battery for your phone. It'll also charge everyone elses phone with the right adapter!

[Q] USB Connected - Screen Accuracy Drops to Zero?

Hey guys.
Any time I connect the phone to my computer via USB, the phone's touchscreen goes bonkers. It wont register my touch in the correct location, it jumps around and registers button-presses that I never pressed, or won't register a firm screen-press at all!
If the USB is unplugged, everything zips along accurately.
Any idea what might be causing this, and how I might fix it?
Just a quick background:
I rooted and installed the lag-fix. I encountered a problem with the lag-fix, restored factory settings, and root/lag-fixed again. The problem cropped up after the factory restore.

That's wacky. Since you've already done it once, I'd just restore again and see if that fixes it.
Also... not sure if this is a side-effect of the factory restore, but guess what suddenly appeared in my Widgets list??

I've since reset the factory settings again; no luck. Still all wonky when USB is plugged in.
I'm considering taking it back to best buy and simply exchanging it for a different one, since I've only had it for a day. I would think that resetting everything to factory defaults would have fixed any software problem. Maybe this is a hardware problem that I just now noticed.
I have heard roomer, that if your usb is to low or to high of a voltage it will bork up the touch screen while plugged in.
it seems a common occurrence on many Android phones that use our style of USB port that if you use a 3rd party usb cable (i.e. one other than what shipped with the phone) as well as many 3rd party usb wall chargers that the touchscreen will either go bonkers or freeze up alltogether.
I've seen the exact same thing happen with my friends HTC MT3G and Motorola CliqXT using certain cables and chargers. Any cables/chargers that do this to my Vibrant do it to their phones too.
Interesting. I'm glad I read all this before I decided to take it back;
the laptop I had it plugged into is so fubar'd, that it would not surprise me to find that it has incorrect voltage...
This happens all the time on my Droid 2, Nexus and Fascinate. I just swipe very quickly and press lightly. However, no matter how many "tricks" I try it's still hard to flip through screens or open the correct app. Hardest task would be to navigate a website. Considering it happens on multiple Android devices and computers I never really put too much thought into it. Just figured it to be a Android bug.
Wow, never seen this. Now I do use the cable that came with my fascinate to plug into my computer, however car charger, wall chargers, and a USB charger (in my truck), I just use the cables from my Droid1. All my chargers are generics... Hmmm..
my htc touch pro 2 did the same thing when i used a gps car charger... screen went crazy
chargers
Ok. So for anyone wanting to know what's going on in the background to cause problems with your phone with crappy chargers....
I first discovered this with another touch screen player *cough*ipodTouch*cough*cough when I was trying to make a universal 4-port USB charging bay that would work with my sansa and my ...other player.
The specification that most device-manufacturing companies use nowadays for charging states that for a device to recognize a charger (and to start accepting a charge from the charger), the data pins must be shorted (connected together). This is what Sandisk, Apple, and several others are using. That is how I built my 4 port USB charger and it works flawlessly (with my sansa, ipod, galaxy, and Cowon S9).
NOW, somewhere floating around on the net are specs that state that some data must be sent/received through the USB's data cable (i believe it claims to need any 2.5V) which basically puts some resistors in to make a voltage divider.with the power and ground and data pins. THESE ARE BAD SPECS. They might have been legit in the past for some other device, but they are NOT what our phones need.
So some of the cheap, off-brand chargers are actually sending random messages to our Phones through the data pins (non-sense 2.5 volts). I haven't heard any reports of this damaging the phone or mp3 players yet, but whenever I plug mine into a charger and I lose the ability to control the screen, I get nervous b/c I know there is voltage on the data pins, and I don't know if it's the correct amount. So I get nervous
...does that make sense?
I had the Droid and the first time I saw that, it freaked me out. It seems to be an issue with touch screen android phones when they don't receive the correct voltage, whether because of a 3rd party cable, or a different computer voltage or something. I was using my blackberry mini usb charger and it would act like it had rabies. Nothing is wrong with your phone.
The charger included is plugged in next to my bed, and I'm using my Droid's USB cable in the computer without issues. That's very strange. I've never heard of this problem.

Sorry dude. It's not just android handsets, and it doesn't (seem) to have anything to do with the proper voltage. I've taken multimeters to the chargers. They are providing the proper ~4.5-5V range. It has to be the data pins.
Although, that's just the chargers I've had. Take a voltmeter to your usb chargers (don't touch the casing at the same time!) and see what their voltage is. But a low voltage just wouldn't charge your phone, and a high voltage would damage it.

[Q] Charging Issue - MHL/HDMI Adapter Samsung s3 lte

Hi All,
I was wondering if anyone had any insights in to this problem I have been having.
Briefly, I have the 4g lte verion on EE's new network. I purchased the official MHL/HDMI adapter which works fine and the video is outputed to my sammy 50inch tv fine. The issue I have is the battery drains while doing so. I belive this may to due to the phone outputting more than it is drawing from the power source. Any thoughts ?
I spoke with Samsung tech and they said a number of people have started to report this issue and they are currently testing/investigating. If this is indeed the case seems a pointless acessory as a long video would possibly drain the whole battery, Im yet to test the full drain time.
Secondly, with a 3rd party docking cradle with spare battery slot which purchased from amazon (http://www.amazon.co.uk/eLifeStore®-Samsung-Desktop-Charger-Docking/dp/B008PPRGFY) also does not charge phone properly. Even with the orignial charger in the ac port (or usb port) . The phone reports as charging but stays the same or decreases. Charged directly from the socket it is fine. Strange!
Any help or thoughts would be greatly appreciated.
Thanks
Ian
It's common. Mine did that too! I switched to my old S2 charger, problem solved
Thanks Ill try that out, any idea why that works ?

No idea man? A design fault maybe? All I know is that my phone took for f#*%ing ever to charge with the USB type wall charger. I pulled it out of the socket and plugged my other other one in that was sitting right next to it and it started charging? Checked a few minutes later and it had climbed considerably so I pulled the USB cable out of the new plug and kicked it under the bed where it now lays resting not to be used again LOL.
USB plug/cord works perfectly fine? So I use it on the computer. My laptop even charges the phone via the USB cable faster than the socket plug (which is usually the opposite - as I am sure we are all aware). So yeah I would say poor design or defective wall plug or both or something? Wasn't going to send my phone back because of it. 2second decision problem solved Samsung phone is great!
Im having exactly the same problem.
I have an s3 on orange and have the same mhl adapter conected to my tv.
I have tried the charger from my s3 which does says its charging when I connect my phone but only for about a minute so I also tried using the charger from my s2 and that just does exactly the same.
An easier way is to buy the official allshare dongle for your hdtv then you can stream anything from your phones screen direct to your tv and can have the phone on charge via pc or wall socket at the same time,
Hope this helps
i suggest you throw away your original charger (slow charge) and its usb cable (loose - actually caused the extsd to become damaged to the point i had to repartition) and buy yourself a cheap usb cable for data (£2) and a 3rd party charger (pref not a usb adapter one - £5) and all should be fine!
I still experienced a small battery drain while using the mhl adapter, however, i froze a few apps with titianuim (ones i know run all the time like utter and tasker, paragon ntfs, easy ums, directory bind etc), and put it on min brightness - works like a charm. I know its a effort freezing apps but does the trick with my phone... Since finding that out i actually keep paragon & easy ums frozen till i need them...
just a few thoughts for you....

[Q] Charges at a certain angle.

I have a Samsung Galaxy S Wifi 5.0, and lately it won't charge naturally (it doesn't charge when you just plug the USB cable to the port and to the wall), but you need to charge it a certain angle (eg move it until you hear the charging sound but afterwards it won't charge when you remove it!)
I have the original Samsung adapter that came with the SGP Box, but I replaced the original USB cable with another one because of the charge-at-a-certain-angle problem. I changed my USB cable thrice now, but the problem persists.
The weird thing is, it charges perfectly on a BLACKBERRY CHARGER. Although the problem is still there when I charge it with the BB charger, it never got to the point where I had to apply so much pressure on my tablet.
I just want to know what is causing this problem and a solution. I can't always use the BB charger since my sister brings it with her to school everyday. -_-
I had the same problem with my Galaxy SI. I was forced to place a book directly under the usb cable so that the phone sloped downwards. I had different luck with different usp cables. My girlfriends usb cable -that was relatively new worked fine as it sat quite snuggly/tight. Others, new or old, that did not sit as tight did not work.
Take you phone to a PC hardware store and test a few.
Hopefully you will find that it is the usb cable that is worn and not the inside of the phone.
Thanks, I'll try that out!

Has anyone successfully recovered from the sudden no charging/USB connection issue?

I'm wondering if anyone has suffered with and recovered from the sudden case of no charging/USB>PC recognition?
I've seen countless similar stories across the web, covering many of the Z Family. Some were simple reset jobbies, and I've seen as in-depth as what I'm assuming is an IC being removed, flux cleaned and re-applied (w ww .you tube. com/watch?v=ZyCeNfc99a0).
I purchased a new charger port and also a new battery, as I figured with all the insane constant burning of my pocket, it could use a new one. I'd hoped it was just a charger port issue, but much to my dismay, the issue still persists after fitting them.
I've tried every single button combination "fix", and all to no avail. Multiple leads, charger units, all that polava. Checked and cleaned connections with isopropyl alcohol, checked for burned-out looking mainboard components, at least those that are visible.
I was having minor inconsistent charging issues for a while, up until last Friday. I figured it was the USB port on the phone or the leads, and put it down to general wear and tear.
Last Friday I was at my mates house with super low battery, popped it on charge round his and I noticed it had died completely and kept boot cycling, like the charger was being plugged in and taken out over and over.
I took it out and tried it when I got home with the regular charger, and nothing. My phone is otherwise in mint condition and has been looked after since day one release in the UK.
I'm wondering if some super helpful person here would possibly have some other alternatives that haven't been mentioned, whether a hardware bypass or some trick that isn't amidst the countless cries for help out there.
Many thanks in advance.
Hello,
I have a problem when connecting to a charger it will go in strange charging mode that actually does not charge. It makes the sound like a charger is connected, no charging animation on battery though...
The problem for me it was the USB cable used for charging (i have changed 5 of them in 1 and a half years). Also same behavior happens when using a under 1A wall charger.
P.S. : The USB cables that i have changed they still work fine with other devices/phones .... but not with my Z5C. I`m not sure what but is definetly something wrong withe phone usb port (and it is not dirt).
no, but
I cannot get a usable USB connection to my computer, but if I hold Volume Up while connecting the USB cable to the computer, the charger LED turns red for a moment, then blue. It WILL charge in this mode, which I think is fastboot mode. Someone said it bypasses the charge circuitry or software, which makes me think that maybe I could go into developer mode and turn on OEM unlocking to see if I can stop it from trying to optimize charging. I also have not tried all the USB connection modes yet.
I tried to charge with this blue light technique on the wall charger, but that did not work. Just ran the battery down again and I could not boot the phone.
I know if I press Volume Down while connecting the USB cable to my computer that the charger LED turns green, but I am not sure it will charge in that mode. I think this is for flashing or something, but since my computer does not recognize the USB device no matter what I do, I don't think flashing is an option.
Oh, and when I do charge the phone with the blue light special (old obscure USA discount retailer reference), for some reason the charger LED flashes white every 4 to 5 seconds, but it seems to keep enough charge to get me through at least the day until I can charge again by same method.
Maybe we can keep pooling info here. I got the blue light technique from someone else on this site, so there are people here who know quite a bit about this phone, thankfully.
Well, I had that issue, too (at least it sounds pretty familiar).

Does your phone also believe to be connected to "something" all the time?
I fear there is some IC fried, although I never dared to open my phone.
My "solution" was to talk my local salesman into giving me a (used, but working) replacement phone, and I did not want him to find any traces of DIY
So, no, I never found a technical solution, probably they just scrapped my phone for spare parts, idk.
The root cause for my error (probably) was a faulty charger, therefore I am pretty sure I fried something hardware-like, but depending on your cause, ymmv.
Anyway, trying to clean your USB port, re-soldering the connector and/or replacing the battery sounds like being worth a try, anyway.
// edit: "cat /sys/class/power_supply/usb/present" used to always output 1, even when not connected. On my now-good Z5C this works like it should (connected ->1, not connected -> 0)
Hey people. I have tried all the tricks for several days. Tried several charging cables. Nothing worked for me. I just brought a new phone, and it came with a cheapo charging cable. Decided to plug it into my Xperia and it worked. Maybe a little fairy fixed my phone when I was out buying a new one. Anyway, I'm love my Xperia Z5. Using it right now. Good luck people
