Strange part after disassembling phone - Xperia SP Q&A, Help & Troubleshooting

Hello! When i was replacing my digitizer i saw that little silver part was free after removing case. I'll link photo of this. Does someone know is this part necessary to work? Usually i have problems with battery. It can turn off like there's no battery left and it only turns on while it's charging. Does this part can affect on this problem?

That's a shield for what it seems to be the antenna circuitry. Has nothing to do with charging/battery.

It took a weight off my mind I've had problems with wi-fi, but it doesn't disturb me that much. Anyway, is this shield important? What can create this problem with battery? I mean, phone could turn off and couldn't rewoke. It only worked after charging it up for a while (battery usually charged to ~90%) May I buy a new battery?

Diamond+GPS+hot day in car = NO CHARGING!!

I thought this issue was related just to me using a car/cigarette lighter charger not specific to my devices but now I am not convinced!!
I have found that with my Diamond (and previously my Kaiser) that on an extended trip in the car, on a warm-hot day, with the device stuck to the dash windscreen, and running GPS software (Tomtom) that the device gets overly hot......no kidding you would think as it is in the direct sunlight (not often in Scotland though ) HOWEVER this is not the issue, the issue is that after a while it just stops charging (~30mins), presumably as a safety mechanism to cut down the heat and to stop the Li battery, er...exploding
My question is: has anyone else had this issue? Its rather inconvenient to arrive at your holiday destination, or other, only to find that your device has been totally drained as its been running (yes it still runs!!) on battery for the last hour or two. Surely this is something HTC must look at!!
Has anyone else had this issue (I've read of a few....hence this post!) esoecially those in a warmer climate, and if not, could it be because of a better? in-dash charging system...
Last note, these device are built with GPS (supposedly for car use!), if this is a real issue then it is what I would call flaw in the device......
Appreciate all comments please (especially from HTC/battery/device charging experts)
Read that already here that the Diamond stops charging when getting too hot! It seems that this is a built in overheat protection maybe for the battery but also for all the other electronic parts. Think they´ve implement it beacause of the very slim device design where there is less room to get rid of higher temperatures to protect it.
I had this issue not on my diamond till now, its only two weeks old, but I can report similar things about my Loox 720 and have red many posts regarding hp 4700 when they where the leader on pda-market a few years ago.
Charging the battery will be stoped by the device-electronics, after reaching a curtain temperature, this is common to all LiIon-charging electronics, I think.
What I've heard about the Diamond is, that it should help to swtich of WLAN, cause it tends to develop much heat.
Hi
Yes, initially I beleived it was to little amps from my 12V charger but I got the "to hot-not charging" tip from another tread in this forum.
As soon as my Diamond got colder it started to take charge again.
My car does not have an air conditioner and I need to put it on the dashbord to get satellite signals. I have not found a good solution yet.

Don't they say in the manual of every electronic device, don't put it in direct sunlight. Li-On batteries dont like to be too hot or too cold, it's not something HTC can fix I don't think, just don't leave the phone in direct sunlight.
My old Kaiser user to do this when I had to go out in the company van instead of my air conditioned car. I found folding a piece of white paper in half and using it as a "phone hat" made quite a big difference.

LOL guys, perhaps we need to put a little parasol on the dash or maybe keep it in the glove compartment!!!
...seriously, I would like to think that this is a flaw, after all, where else can you safely put a "GPS device with street naviagation in your car"...it has to go on the w/screen or dash!!

Yes, I've hadi the same problem. The only solution that I've found is to put the phone on a support near the car fan, so it can be cooled. Otherwise when became too hot stop charging and after half an hour the battery is totally out. !
It's a good thing, if you charge a battery in a too hot environnement, you kill it.
I can confirm this. I tried to navigate for 2 hours in my car, TD attached to my w/screen and after half an hour or shorter it shut down. And I couldn't get it on either. Wouldn't charge or anything. I had to wait a few minutes and then it would charge again. This happend two times during the same drive. After that I placed my TD infront of a fan and worked like a charm..seems like it gets to hot.
Oh yea btw. I also noticed I had, what looks like melted plastic, inside my phone after the drive (attached image)

something like that would be perfect. Alternatively, using something like AEButton plus to map a key to turn off the screen will help as it will lower the power consumption. you can still hear the turn by turn instructions so you can still get where you are going most of the time, and the lower power drain will allow the battery to charge for longer without the temperature protection kicking in.
What i usually do is to just putt the air-con full blast on the winshield, it is usually a better idea to keep expensive electronic equipment in the normal operating temperature range anyway,

On a different note, has your Diamond received a soaking? It likes like the water-sensitive sticker (used by HTC to tell if it's suffered water damage) is red on yours which suggests it has...?
Mathew
Happened on the Tytn and Tytn II as well~
Well, I am so sad to see this is still an issue.
My 8525 (had 3) and my Tilt(s) (I have 2) and they have run into the same problem of not charging under heavy use; i.e; Backlight on, Tomtom, GPS all running.
I so hoped they would have fixed this.
ATT has replaced all the phones that developed the problem so far.
I think one of the comments about being designed for in car use is amusing especially because most (if not all) GPS software says "Do not use while driving"
Batteries do overheat, and it's better that the charging is stopped, than you having a £400 fire on your dash board!

for example in iGO 8 there is an option to turn on the screen backlight only before crossroads - settings - device and you have an option to have light olways on, device settings or inteligent state when light is always turned of after passing crossroad and turning on some x hundred meters before crossroad

The device should stop loading, before its beeing killed. Have to take care of when its possible to load the device and when not is nothing, what I've red in any user-manual before.

Hmm no. It hasn't recieved a soaking. The phone has always been dry inside my pocket . Are you sure the red "thing" indicates the phone has been suffering from water damage?

My sticker/laber is white of color, so it could be be it came in contact with a liquid.
I repair notebooks and similar sticker, labels & coatings are used that change color when the come in to contact with a liquid. I've also asked a college of mine who used to repair mobile phones and he also confirmed that the put in stickers or laber or special coatings that react to liquids so it easy for the engineer to see if the machine is valid for warranty or not.
But I can't say for sure that the sticker I see on my phone that is white (& your is red), is such a sticker that changes color wen it comes in contact with a liquid.

Display issue with samsung note n7000

My issue is with samsung note n7000. When battery inserted, screen is constantly on with strange horizontal lining. Also happens when display is dimmed. I took the phone apart and cleaned it with alcohol, that did the trick for about 20 hours. This morning started to do the same. Also, there's no warranty left. Posted a picture to show what the screen looks like when battery inserted.
I guess your battery is old..its time to change battery..I had faced same problem before now its allright with new battery...
I am noob.BUT.I am learning
tried with 3 different batteries... don't think it's battery related issue

Could be GPU overheating.
Could be screen overheating.
You could try underclocking the device to 800MHz, it will be dog slow, but should indicate if it is heat related.
Bottom line though, you probably need a new screen.
Search XDA/Google for how to fit a new screen.
Quite often those that have fitted a new screen will expalin why they did so.
If their symptoms are similar to yours then you need a new screen.
You could always give Samsung a bell (that's a phone call in case you're not UK).
Could be resolved

I think, this has happened due to overheating or overcharging. One of the connection point has become loose or soldering has melted. Get this phone to a service station to get this fixed. I dun think u need a new screen.
If you want to try for screen replacement, here's the youtube link:

You're probably bang on there.
It does sound like loose connections on reflection.

I have an extra n7000 as sparepart phone, which has working screen, did the same thing with another screen. Only when i changed the Charging Connector unit from the other phone, the screen went black, but didn't turn on. Could the charger unit cause all this?

I honestly don't know.
I don't know enough about the electronics in the device.
If you can find a service manual for the N7000 this might help.

[Q] Moto X battery pinout/external charging ?

Hey,
Does anyone know the pinout diagram for the moto X battery, the CS-MXT912SL
http://www.techtek.cz/CS-MXT912SL
http://www.batterybay.net/Battery-for-Motorola-XT912A-p/motorola-cs-mxt912sl.htm
I intend to charge the battery externally and try to get my phone to boot up.
I basically walked into a swimming pool (yeah I was that stupid to have the phone in my shorts ) with my moto X,
and after a lot of drying the parts and assembling it back, just the green light near the ear piece lights up for a few seconds- when its plugged into the charger.
I can tell the charging circuitry is damaged, since I don't see any voltage readings at the battery input terminals,
which seem to be affected very easily as seen in my previous post here : http://forum.xda-developers.com/moto-x/moto-x-qa/moto-x-battery-stuck-10-charge-t2845065 (motorolla fixed the phone for me after that)
Thanks for any help
Unfortunately chasing down water damage is usually futile. You replace one thing and find other things are fried.
Usually saving your time and money for a replacement is better than spending it on a water damaged device.
Usually they either are OK right away after being disassembled and in a bag of rice a few days.... Or they are dead. The fact you powered it on, or tried by plugging it in probably sealed it's fate if their was any moisture still present I'm afraid.
Sorry for your loss. ?
---------- Post added at 10:28 AM ---------- Previous post was at 10:26 AM ----------
And questions go in Q&A. ?
Thanks for your reply Darth,
I did dry out each part completely before turning it on (diassembled everything, hair dried, left it in an air conditioned room - disassembled for hours) .
I understand what you're telling me regarding replacing the parts - in this case I really think( I have reasons for this) its just the battery charging section thats shorted itself out and drained the battery.
Does anyone happen to have voltage measurements of the charging terminals of the battery, it might help me start off with some testing.
My real goal is to retrieve the data on the onboard emmc storage before replacing the board.
Im going to attempt to either :
1. Attempt to power the board up by charging the battery externally
2. Attempt to interface the emmc in some way to retrieve my data.
I know this is a long shot, but any advice/help would be useful
Thanks,
As an update to this thread,
I hooked up the battery directly to my bench powersupply at 3.18v and the battery came back to life!
The phone booted up! and works perfectly OK (speaker, gps, gsm, 3g, wifi, display, everything).... except for the MIC which I think is dead.
I've ordered a replacement part from aliexpress and hopefully can use my MotoX fully again!
PS: the battery pinout was (+) all the way left and (-) all the way right on the battery connector.

Can you pm me the link to the mic? And was it the front mic that doesn't work? Cause my issue is the front mic as well since it doesn't work.

After someone stole my wife's Moto X, they threw it in the garbage where it mixed with some soda. I was able to track it down but then it died and now has the same green light behavior you're describing. Were you or anyone else here able to fix it?
I tried taking it apart and rinsing everything with 99% isopropyl alcohol, but nothing seems to have changed.
Hey,
Yes, I was able to recover my phone - I suggest you make sure the phone is properly dried out before you try what I did.
I had the same symptom as the green light, which indicates it doesn't detect a battery or the battery is completely drained out.
I hooked up the battery directly to a bench powersupply, applying 3.7Volts for about a minute (current was less than 1A)
after that as soon as I connected the battery connector to the phone, the screen lit up with the battery symbol,
and it was charging at around 40% (I had the usb charger connected)
The battery pinout is (+) all the way left and (-) all the way right on the battery flex connector.
Good luck! let us know how it goes
PS: I just received the mic part and am about to replace it, looks like the mic was the only thing that didnt survive the water.

Wow, it's weird that the phone wouldn't even try to charge your battery until you jump-started it like this. After that everything but the microphone worked? I'll definitely give this a try, maybe by transplanting the battery from my other Moto X. For now the green light on the bad phone stays lit for about 10 seconds before it turns off, and the phone doesn't seem to be able to do anything else.
Everything except the micrphones(s) works fine, from what I figured there are 3 mics on the phone.
The main mic for phone calls is next to the usb connector, this seems dead.
The second mic which is near the front camera, I *think* is the "touchless control"/"google now" mic, this doesn't seem to work as well.
No idea where the third mic is but Im pretty sure that did not survive either.
As of now its a bit hard to replace the mic, since I don't have a hot air station at hand,
I can use the phone with a handsfree headset for the mic and it works just fine

[Q][HELP] Z1 Dead After Teardown

hi every one...
i need a littile help here...
its about 3months that my battery is somehow acts funny and will turn off at random percentages! (seems dead and a little bit got fat)
i just open the phone ,dis attached the battery , and again attached it and tried to turn the phone but it wont...nothing happens..when ever i remove the battery from the board and plug the phone to ACcharger,the led goes red all time on... any one knows that its a battery problem or something wrong from the board?!
You need to check if you ripped some of components off the board near the battery connector, or bent connector itself.

Hardware defect - Battery or Mainboard issue?

Hi guys,
I had to change both display incl. frame and battery because a barbell fell on my Mi9. This bent the phone at the place of the battery and completely destroyed the display.
I was able to repair the phone quickly, but unfortunatly I did not glue the new battery. Now I was mountain biking and due to the vibrations the battery was torn from the mainboard and parts of the battery cable got stuck in the connector. I had these parts removed carefully by a watchmaker and he assured me that the connerctor looks undamaged.
But now I have the problem that the phone won't start when I insert the old (minimally) bent battery. It does not respond to any input. Only when I charge it, the LED is blinking slowly and the MI Start logo appears for 1/4 second. This process is repeated continuously. The battery also warms up slightly, showing me that it is being charged and that the connection is basically established.
Can you detect a defect on the board by this error description or is this a "typical" battery problem? Or does this error description look familiar to you otherwise?
Thanks for all suggestions,
Mike
Well I'd say that will be a hard problem to diagnose without knowing what to look for, and I definitely don't know but what I'd suggest so you can rule out the battery problem is to try a different battery in the phone and see if you get the same response. If it works happy days problem solved. If not it is more than likely a main board problem or charging connector.
