Issues with charging - Google Pixel Questions & Answers

Hi All,
First time here so hopefully posting in the correct place, apologies if not.
Bought a pixel from ebay, described as a google refurb unit.
After a month or so the phone microphone went dead, and having read a few differing threads decided that a new USB-C board with microphone would sort it.
On replacing this part i managed to sever a corner of the screen cable, so I bought a new screen and installed that.
All looked fine until I realised that the battery was in fact not charging, although the phone stated that it was.
I installed an app called battery monitor that showed the battery status as overheat and at a temperature of 67.2 degrees C. I knew this was wrong because the battery didn't feel warm at all, I decided to swap the new charging board with the old one because this was working fine previously. The phone still wouldn't charge. I did a factory reset on the unit to hopefully wipe the battery log, in case it was something like this.
Then I bought a new battery and have fitted that after swapping out the USB-C board again, still not charging.
This is where hopefully someone can help me.
I have no more ideas - please help?
Thanks in advance

[Q] HTC Desire S Charging Problem

Hi All XDA Members I have a problem with my new phone (HTC Desire S) and was wondering if anyone could help me with what might be causing a certain charging problem, soo the problem...
The phone seems to think its being charged sometimes even when disconnected and is failing to charge the phones batteries through the standard wall charger or USB connection, therefore I am having to charge the batteries via taking the battery out of the phone and charging it in a separate dock I have purchased.
Sometimes as well after charging the batteries in the dock then placing them into the phone and turning it on the phones LED orange indicator glows and still thinks its being charged even when it has had a battery unpresent in it for several hours?
Does anyone have any possible outcomes to what this may be because of? Any help would be much appreciated?
The phone is running MIUI Android custom ROM with s-off.
Thanks,
Daniel
NOTE: I know I said "my new phone" but it is second hand and I purchased it with this problem hoping to come up with a fix.
have you tried other roms and experienced the same problem? or have u only ever had miui on it?
Hi, cheers for the quick response, and no I have tried multiple roms so far and all same problem.
Could it be anything to do with me getting cheap replaceable batteries for the phone as they are also not at the standard 1400mah but at 1450mah or should this not make a difference?
Cheers

this could certainly be the issue! so your saying it doesn't have a original htc battery? if i was you, the 1st thing id do is try a genuine 1. try to borrow 1 if u can from a friend or drop into a phone shop and ask. If it doesnt solve the issue atleast u havn't blown 30 quid on an original battery
you should try a genuine battery for sure! also their capacity is 1450mAh not 1400
check amazon uk

Just discovered guys that the batteries are actually 1500mah? Is this the problem and is their anyway to configure the phone to run with these batteries properly?
I am beginning to think whether it could be because of previous water damage if it has suffered from it before, but I would not know or be able to find out myself if it has been water damaged.
I was also thinking it could be this as maybe a possible short it happening on the main board and is causing the phone to think its constantly charging? Maybe?
Cheers Guys!
Can anyone help pleaseee!!

What makes you say that the battery is 1500 ? It's 1450.
HTC's own website says
Code:
[B]Power & Battery[/B]
Battery type:Rechargeable Lithium-ion battery
Capacity:1450 mAh
Hey guys (apologies I see this is a month old)
The issue Lowery91 has seems to be exactly the same as I had with my desire s. I'm breaking my heart trying to find out what's going on.
I have one of the original batteries that came with the desire S. The phone has these issues without being rooted (which I intend to do to see if I can amend it).
However for me it first started acting strange when I plugged it into a car charger.
Again sorry for rehashing this post but if anyone could shed some light on this I'd really appreciate it.

I'd suggest that you contact HTC support and get them to send you a replacement battery, explaining that yours is faulty, don't send your existing one back.
Swyped from my Desire S using XDA Premium
i think it is not a battery problem, i have two htc desire S and one today had the same problem, i tried to change batteries but when i put battery from other desire S i had the same problem, booth batteries working perfectly on second phone.
So i think it is phone problem. Something like voltage loss or etc. Because i thinkphone gets not enouth power to charge battery. But this is only my opinion.

Check this: It was a small pin inside that had come out. It connects the USB to the motherboard and is visible just below the battery. I fixed it in 10 mins with a bit of R&D. Now that you know, it will take you less than 10 seconds.
Having opened up the phone quite a few times now, hopefully i can give a couple of pointers towards this...
There is a small connector with flex cable that connects the USB port to the main board of the phone. To get to this easily, remove the batter, SIM and memory card. Also remove the 4 torx screws at the bottom of the phone and gently slide out the plastic clip that holds the battery in place. You will see this connector at the right side of the phone if its facing down. Just push it up with a small screwdriver and push it in on the connector again. Reassemble.
Hopefully this is the cause of the problem in the first case! Please do this with care..
Disclaimer: I am not responsible for bricked phones/broken usb ports, etc. Please do this systematically and all should be fine.

[Q] Need expert help, is it bricked/savable??

I have a TF101 that will not charge or power on. I rooted it a month ago and it was running great. My wife lost the charger and had plugged in the tablet USB cable to a cell-phone charger , I found plugged into a week later to the phone charger, unplugged and attempted to turn that tablet on, it flickered on for a moment and then died (loading screen) :silly: ya stupid right?. I them found the right charger and plugged in the tablet and the light indicating that it is charging does not come on. I look and looked online for help. I'm pretty sure its not a charging problem as I did the freezer trip on the charger box nothing, I bought a new charging cable and charger off Amazon, nothing. Still not coming on when plugged in or anything (That is why I don't think its just a battery issue from what I have read.) The connection on the tablet looks ok on the bottom and both the old and new charger will power up and charge the keyboard dock just fine. Has the tablet been bricked dead?? Nothing I can do??
Thanks for your help and reply on this your all awesome
P.S I also tried a slow charge through the usb port on my computer over night and left the tablet plugged into both chargers over the course of two different nights. No luck.Also can't get into (Apx mode) the volume up and power held down for 15 sec does nothing.
Looks like you're stuck. You'll have to make a decision whether to buy a new battery or not. A colleague of mine solved a similar issue with a new battery off ebay, but it doesn't mean there isn't another hardware issue.
When you say the charging light does not come on, you mean on the dock right? The tablet itself doesn't have one. Did you try to just charge the tablet without the dock? Did you try to open the dock and flip the switch?

Yes the charging light on the dock does come on I thought I saw what looked like a light on the tablet. So the dock is charging and working just fine.
A battery like this? (I would put the URL but its not letting me since I'm new.
I'm not super good would opening stuff up how hard would the battery be to replace? I did see a thread on opening the unit itself looked complex. Also Any more trouble shooting I should do? I may just buy a replacement off ebay and sale my old one. Also can you tell me if its bricked or not or whatnot? I just don't want to put out fifty bucks for a battery and not have it work
Well if it won't turn on, it's difficult to troubleshoot further. The general rule is: As long as you can get it in APX mode, it's not bricked; with hardware issues as the only exception. In theory, it should power on with an empty battery (and start the charging process), but I have no idea about a dead battery or how the unit is made to handle such cases. Give it some time I'm sure someone else here can answer that question from experience.
Replacing the tablet battery is not too hard, but it's a long task that requires patience and some tools. There's some videos on youtube and others about how to open the unit safely without damage, and decent tools are cheap assuming you don't have precision tools. By opening it you can troubleshoot it a little more. Inspect the battery for physical damage, like being oversized, which means it's likely dead. If it looks in good shape, try disconnecting and reconnecting it to the board; sometimes reseating a connector solves the issues. Also look for any obvious damage inside while you're there. Even if you don't know much about electronics, an obvious burn mark on the board is never a good sign.
If after all that it still won't power on, then yes you could check out ebay. Just make sure lots of people have bought the same from this buyer (the more the better) and they gave positive reviews for the product (stuff like "still works after a year"). Make sure it specifies it supports the tf101 and it should be fine.
Honestly from what you described in the original thread, I wouldn't be surprised if over-amp or something like that damaged the battery. Hopefully it's only the battery but as I explained, it's rather hard to troubleshoot. From personal experience developing boards like that, there are usually protections in the device to prevent damage in case of over/reverse voltage/amp. Depending where the battery is connected in the circuit sometimes it's protected sometimes it's not. I have no idea how Asus do it so take it with a grain of salt.
Can you provide said phone-charger specs? Volts/amps/exact model?
Edit: P.S. The device or dock will not charge through USB. You need the actual wall charger.

The phone charger that it was plugged into was a Galaxy S charger. 5v===0.7A. Doesn't seem high enough to have done anything...but I'm definitely no expert. (Literally)
Sounds like its a good idea to open it up then to check on the battery, if burned or oversized then I will buy a new one (As long as I don't see burnt marks) If the battery looks fine I'll try the reconnect. And cross hy fingers. Thanks for all your help so far. Any advice on where to buy the tools? Deal Extreme good for that Amazon?
No tools are required, ands its easy to get into just be carefull pulling the bezel off as the tabs that hold it on are quite weak (i broke a couple when i ripped mine apart in anger lol) after that their is about 10 normal screws until its open. It could be the case that the battery just needs to be unplugged and re-plugged in.
Its a strange problem you have there, the power output from that charger is less than half of what the standard asus charger outputs, if something is fried id call concidence as ive plugged my tf101 into various ac-usb adaptors with no troubles. Its a complete guess at this point but its almost like your tablet is suffering from the 0% issue thats common in the docks, where it refuses to charge if completely drained (afaik with the dock this is fixed by disconnecting and reconnecting the battery)
Also did you get an official asus charger as a replacement? a few of the cheaper ones dont even output enough voltage to fast charge the tf101.

[Q] [q] battery charge indicator incorrect after water damge and restore

Hello,
I have searched and searched this forum to find any threads or posts that describe this problem. I have found lots of similar ones, but none like this, so that is why I have started a new thread. If I missed this topic somewhere, I apologize for not having found it.
My wife and I both have Skyrockets (GSII - I727). Stock AT&T ROM (not rooted), but both unlocked. Mine got partially wet last week (toilet incident, would rather not elaborate, but I will answer the first question everyone asks - yes it was a "clean" toilet ) Anyway, I immediately liberally rinsed all ports with alcohol and warmed gently with a hair dryer. After drying I powered up, and everything worked, except the battery percentage display (with a variety of completely fresh and fully charged batteries), would only show in the 50 - 68% charge range, and the phone seemed to die at about the rate one would expect commensurate with those numbers. Put it in a bag of rice for 2 days. No better.
So, after reading here and watching several YouTube videos, I completely disassembled the phone. cleaned all ports, ribbon connectors, mother board, etc. with CRC electrical contact cleaner spray using the spray tube and a very gentle toothbrush. I paid special attention to the micro USB charging port, and all other contacts and circuits that seemed to be related to charging, though I am by no means an electrical engineer or technician, so a lot of it was guesswork. I made sure all was dry and new looking. All contacts intact, no visible corrosion or bridging, and reassembled the phone perfectly (pretty proud of myself for not breaking anything in the process!)
The phone still works great, except for the battery percentage display issue. I have tried everything I've read on this forum about recalibrating the battery meter - discharging fully and then charging up. With the phone on, with the phone off, every permutation I can think of. I tried clearing the cache and rebooting. Still, the maximum the display will read is 68% and that's it, and the phone behaves and dies like it has a battery that is only 68% full, even though I know I am putting 100% charged batteries into it. I have verified this by putting the same batteries into my wife's identical phone and it displays 100%.
If my phone we're lasting as long as it normally would with a fully charged battery, I wouldn't be so bothered by the display being inaccurate, but that is not the case. I've downloaded CPU SPY and some other apps to see if my phone is using an unusual amount of battery resources, but it is not. So, that's the story.
I am not afraid of rooting the phone, and I have no warranties left so I don't care, it's just that from what I've read here on the forum, people with somewhat similar issues have not benefitted from rooting and then running apps or programs that are only available to rooted phones, so I would prefer not to go down that time consuming route, if all I'm going to do is hit another dead end.
So, any suggestions or comments would be greatly appreciated! Thanks in advance.
Best regards,
Ron M.
This may sound dumb, but did you try a factory reset?

Thank you for your post sireniankyle. Not a dumb question at all, and actually the answer is no. I have certainly considered it, but I haven't done it yet for 2 reasons.
The first is that from all the research I've done, trying to find others who had similar experiences (I have yet to find anyone with the IDENTICAL problem), they have all without exception reported that factory reset did not solve their problem.
Second, because of my previous experiences with doing a factory reset, it seems that no matter how well I am backed up, that it turns into a very time consuming process in getting the phone tweaked and with all the applications and setting back to where I had them. So, I've been holding out and saving factory reset as one of the last resorts.
The other last resort is to root the phone, because apparently there are some apps that might be able to reset the battery counter that will only work on a rooted phone. However, again in my research thus far, I haven't identified anyone with a rooted phone with a similar problem who has had succeeded in solving the problem.
Perhaps this weekend if/when I have the time and patience I will attempt one or both of the above. It's just that I have such low expectations of success that am reluctant to start down those paths.
If you, or anyone else on this forum can point to any experiences where these methods actually worked for someone in this same or similar situation, I would very much appreciate if you could direct me to the appropriate thread.
Thanks again very much for your input, and your further assistance and suggestions would be most appreciated.
Best regards,
Ron
No problem. I just try to help out where I can.
I can't say that I have had any of these issues. I understand the issues with backing up, but if you install twrp, you can create an entire backup of your phone. I've done it many times before without issue, and if resetting it doesn't work, you can still go back to your original set up.
It seems like you may be a pioneer in this particular issue. I hope you figure it out. Both for yourself, and for others who have this problem in the future.

I used to like being a "pioneer", but as I get older now I just want my stuff to work, and don't have the time or the patience to go where no man has gone before Nevertheless, I absolutely hate to admit defeat, and now that you've turned me onto twrp (do I have to root first to use it?), then perhaps that will make the experiment less time consuming, so I may try this weekend if time allows.
In the meantime, the phone continues to function normally in every other way. I simply carry a couple fully charged batteries in my pocket throughout the day, which are of course 100% charged via my wall charger, but show as 58% as soon as I put them in the phone, and then die at approximately the rate one would expect from a 58% charged battery! Weird huh?
Best regards,
Ron
Was given a Skyrocket the other day which suffers from the same kind of problem (had massive water damage), but the battery percentage is stuck at 0%. So of course it will not even boot up. (Fully charged the battery in a wall charger.) Only thing the power button will do is vibrate the haptic feedback given at first power on, no screen activity. Funny thing is it'll go into Download mode perfectly normally and sit on the Odin mode screen till I assume the battery dies. However it will not go into Recovery mode. Plug in a USB charging cord to charge block or a port on a PC and the phone powers on and works perfectly fine, though forever stuck at 0% battery.
So the only thing I can think of to quickly get around this is without solving the problem, if in fact it can be, is to get a charging case. Like such, for example. http://http://www.ebay.com/itm/XPAL-Galaxy-S2-Skyrocket-PowerSkin-Case-i727-Extended-Battery-Gel-Cover-OEM-New-/310903753323 Had one similar before for another model and when installed it shows as if the phone is charging. So in theory will work for me, though powered strictly by the cases battery. Should work for you even better as you'll get the cases battery life then your own 58% worth of battery life. Edit, just realized when the last post was made, you probably have a new phone and moved on by now.
**I'm going to try to craft myself a homemade powered case yet, have tons a batteries kicking about.

[Q] Stuck on booting up Samsung screen

Hi,
My Note Pro 12.2 P900 64gb is now stuck on the samsung screen of booting up and I am wondering if anyone can help me figure out what to do next.
I was experiencing the flickering issue for the last two weeks which got progressively worse and eventually caused random rebooting. One time last week it started booting slower and then it wiped out some widgets on my start screen and the apps in touchwiz but most everything else was OK. Then yesterday it would not boot up past the samsung screen. It charges up OK, and I can get to Odin where it asks if I want to load another operating system by holding power and vol up. But unless it is plugged in, just holding power off puts it in a boot loop.
The other part is if it is stuck and I hold power off it usually vibrates twice before boot looping.
I rooted the tablet when I got it, but still run stock touchwiz, I just needed some rooted apps namely LMT pie controls.
Can anyone please point me towards what to do next. Thank you very much for your help.
I guess wiping data and factory reset is your only solution right now
I shall warn you you could lose your data so I hope you already have a backup!
And also I've read that lollipop fixed flickering issue in p900 devices
I hope everything goes well for you
Good luck
hey there, you are not the only one, check this post. it seems is somethig related to battery issues

When power on, try pressing on the back, near the center with your hand. to see if it can boot normally,
Keep pressing while power on. if it works I will tell you what causing this problem.
https://www.youtube.com/watch?v=VeSG0hHpAG8
here you can look by the minute 2:30 where the connector is located, basically under the samsung logo. I'm not doing tests yet because i have a busy day ahead
Thank you all for the responses. Holding down the back while powering on does not help. I do have the flickering thing and that started leading up to this. Lay night I took it the battery and disconnected it for a half hour and that did not help. Looking at the connections with a 20x hand lens did not reveal any cracks.
I don't remember how to wipe the data off the device, I got it right when it came out rooted it with cf root and never got around to twrp. All I wanted was LMT and Xposed. I never even updated the OS.
If anyone can help walk me through this to get it running again I'll send you a green poetic skin used once or a white well used GumDrop hideaway case I tested for work. I just would like to get this running instead of needing to purchase a new one.
Thank you again. Sincerely.
Flickering screen is caused by cracked battery connector which cannot be seen under magnified glass. Re solder will fix it, trust me I did fix some of them

So resolder the 6 posts connecting the battery connector to the motherboard? Is there anything special I need to do that, just my soldering iron with a fine tip and solder? Anything special I need about the solder or do I need a wik or anything? The last time I did any soldering work was about 25 years ago.
Also will this fix the bootlooping and hanging on booting up at the Samsung word on the screen? If it is not going to fix that problem, maybe I should look at something else first.
Thank you very much again for your help.

First, pressing the battery connector help your tablet to boot is a confirmation of cracked battery connector solders. 90% flickering problem is from cracked battery connector. 10% is bad battery. You should fix the battery connector first as it's major defect seen in many Samsung tablets. Re solder is simple, apply flux, then heat these pins and add more solders as possible to secure these pins. Even new main board, this connector will crack just after 3 or 4 months depending how you use your tablet, especially with who using it on their laps. The main board sits on a flexible LCD and only 3 screws to hold it to the frame at 2 speakers. You don't need to remove the main board, just disconnect your battery and re solder the connector from the top.
Be careful as this connector is very close to other components. Trust me, this re work will fix this problem as I have seen in some cases, battery jumps up from 8% to 45% after the re work, other cases pressing the battery connector help the tablet to boot or stop flickering.
This person applied the fix and succeed.

I have the Note Pro 12.2 and I had this same screen flickering issue. It would start to flicker at first around the 38% mark. I did research online and found this thread and many others. I tried the software fixes like the enabling of Developer Mode and screen brightness and other tries, but to no avail. When I pressed on the back of the tablet, the screen flickering would stop but then shortly return. So I saw the fix of trying to raise the motherboard which worked for about 2 weeks, then the screen flickering did return. It would then start to flicker around the 58% battery level mark and when it got down to around 26%, the tablet would shut down. When I plugged it in, it would show battery level of 0%, then quickly jump back up to the 26% mark when it shut itself down. So then by this time, I saw more of this thread and now was shown the soldering of the battery connectors. I had soldering equipment, but it was too large for this repair as these 6 pins are very close together. So I went to the hobby shop and purchased new equipment for about $30 with a smaller pin to be able to do this. Now, I am not an electronics guy and my past experience was replacing two bad capacitors on my Plasma TV when it went bad. That was the extent of my experience to date. So I opened up the back of my tablet and soldered the 6 pins again and the screen flickering has not returned. I am on my 5th battery cycle from 100% all the way down to 2% and the screen flickering and shutting itself down has not returned. Some people have said an electronics guy will do this for you for around $30. Well, I spent the $30 and did it myself. I want to thank the people for posting the solutions here as the soldering worked for me.
And from this post, a confirmation that repair center will do the same thing to fix flickering , auto reboot, auto shut down.....etc...all problems caused by cracked battery connector ( Connector Header ):

Ok I'll try to resolder it this weekend and report back. I think that my pertinent problem is that I have both the battery issue AND another problem that the tablet won't boot up at all but I will try the battery fix first and see what happens. Then I will report back.
Thank you very much for your suggestions.
Your feedback is very important as I see many " Hit and Run " users, they get the solution they need but never post back. Your first priority is fixing the battery connector, then next is the battery if problem persists.
This is a hardware defect I have seen in many Samsung tablets: battery capacity fluctuation, quick discharge, auto reboot, auto shutdown.......all come from battery connector . Read the threat Flickering Screen you'll see others try all solutions but never work because they don't know this is a hardware problem coming from this tiny connector.

Battery Problem, possible motherboard damage ?

Hi all
I have had my nexus 5 for a while now and just as i was flying overseas some strange things happened.
First the vibration stopped working which i knew was a loose connection on the back of the phone. Holding that area down would get it working again. Then the touch display stopped working. The LCD worked but could not touch anything to unlock the phone. I disassembled the phone and assembled it again and strangely it worked again although i didnt see anything obvious. Then is happened again...
I disassembled the phone and played around with it for a while and noticed if pressed down on the connection where the flex cable connects to the motherboard it would work again. but when i would release the pressure it would be funny again. I did this a number of times until eventually the whole LCD/blacklight should shut off. Now i can rarely get it to display anything. The phone is working because the LED light would flash and i can hear the messaged coming through. I just cannot see anything.
I replaced the flex cable with a new one and still the same issue. I replaced the LCD + digitizer + frame and still the same issue. I guess its the motherboard. Can i fix this ??
Now for some more issues:
I bought a broken Nexus 5 while overseas and i swapped the motherboard out and everything works! So it as definitely the motherboard. However, the second motherboard is having issued the the battery. I have every indication the battery is charging. However the battery percentages is stuck on 40%. It would flicker around 39% 40% instantly and when looking at the battery graph on the phone it is noisy, it is not a constant line. The percentage is not a true indication of the battery charge. I cannot get the phone to turn on just by the battery itself no matter how long i charge it for. I have swapped batteries out and i still get the same issue. I have swapped flex cables and still the same issue. Could it be that the second motherboard is also damaged??
I used the amphere app for a while while i had some power and it shows 100mA while charging but a voltage of 0V! When I unplug the cable it will shutoff. Sometimes i cannot even boot it up while charging.
Amphere showing 1%

What is wrong with these two motherboards?! I do not see anything obvious on the board itself.
I now see the new Nexus 5X is out but i am hesitant in buying it...This is the first phone i have had major issues with.
PS, i gave the latest updated
Thanks for your help guys. I will provide whatever information i can.
It sounds like your 1st phone is having the same problem I have with mine, which is described here: http://forum.xda-developers.com/google-nexus-5/help/main-board-socket-flex-cable-super-t3217281
Use a magnifying glass to see if any pins on the socket are broken. I still don't know if it's fixable.

Although i cannot find any abnormal pins...
