hI,
My TYTN II deaded. When a I plug the power only the red light goes on. I did the procedure to put three batteries 1.5 v to charger the battery. After that, I plug the battery on cell phone and plugged the charger. The led goes ambar but after a I time goes back to red. I don´t know if the mobile is sending the correct voltage to battery. Some body know what is the voltage on the four pins in that the battery is put on the mobile? I measure betwen first e last pin and I haved 0.9V.Some body can confirm that?
Thanksssss
Looks like you have a bad charger. It should be 5 volts. Try a different charger if you have one or a USB port.
HI,
I tried other charger and usb port and have the same voltage on the pins on mobile. This voltage that I measured are back on the mobile where I plug the battery. I need to confirm what is the voltage on this pin to Know if I must change the battery or if my mobile has another problem.Thanks
SEARCH for Red Light Of Death (RLOD) And read the answers in there.
Hi, I searched for Red Light Of Death (RLOD) but there is no answer for my question that is: what is the voltagen in the pins or which voltage in each pin of back side of the mobile?. Thanks again

I don't understand why you need to know that though. The Red light of death is a known issue and it's well documented in the relevant threads what to do about it. Although the HTC supplied chargers can be very poor quality, I had one completely fail after 4 uses or a couple of weeks, that wouldn't explain what you are experiencing. Do you have a different (spare) battery that you can swap in? Are you using the original HTC supplied mains charger? Have you tried carefully cleaning the gold connector springs on the phone and battery with a cotton bud/Q-tip and contact cleaner or IPA? I did have the problem of my battery only charging for a minute or so and then going off charge (with no light) but a terminal clean as above resolved that for me.

Flying, I did the test that I founded in this site put the battery to be charger with 3 AA BAttery and after that, the mobile turn on.I put the charger ( I have two) the led changed to ambar,like as charging, but I saw that the mobile wasnt charging, because after a time the led goes RED again. Because this I would like to know the voltage, than I can determine where is the problem. I use the origina battery (SAMSUNG) e the 2 chargers that came with my mobile. thanks
Two Things.
First, People have solved the RLOD without knowing the Voltage. So I don't know why you knowing that the Battery Puts out 3.7VDC at 1350mAh would help you solve the problem.
Also, The reporting of Voltage information to the Windows subsystem is sometimes flaky and the only true indicator is the Amber Light.
Secondly, If you are having a RLOD and you want to know the voltage. Post that question in the RLOD thread. It will help the next person who has the RLOD and wants to know the voltage for whatever weird reason.

If you're attempting to charge 3 AA cells for any length of time with the default charger, the different internal resistance/cell characteristics and the fact you have no temperature feedback thermistor signal may account for the red light after a while. My suggestion is to try cleaning the terminals on the battery and phone as already described with contact cleaner or IPA. Then commence the AA cell trick but remove the charge after just a short time (before the light goes red), shut it down and put in the original (cleaned terminal) battery and try again. If it still plays up, JimmyMcGee is right in that you should move over to the relevant pre-existing thread. Good luck.
Hey I was wondering if something is wrong with my device.
I am encountering weird things regarding recharging the device in reliability charging up.
So i am using the original charger which came with the phone, the phone is just like 3 month old i didnt notice anything like that earlier.
So when i am charging the device, sometimes it stops charging, Today I encountered it charging to like 56% and afterwards no more charging so when i got up, my phone was 14% left even when plugged in.
I encountered it several times recently that it stuck recharging at around 50-ish or 70-ish %.
charging usually takes up reasonably long. About 10% an hour. In Settings -> Battery it sometimes it displays USB even when it's charging via AC.
I am not running any fancy apps which drain the phone or clock cpu.
I am running 4.1.2 I9305XXBLL3 Rooted.
Anyone have any suggestion?

Samsung charger that come with the box really charge slow because it only supplies 1Amp.
But for your case seems different. Before checking the software side... have you checked if it's the charger or the cable itself has the problem? Try using other charger.
do you think a nexus 7 charger works fine w/o doing any (more) damage?
Many times it's because of dust and dirt collecting inside usb port. Clean it with compressed air or small brush and try again.

i am aware that dirt might be the problem, but i've took my torch and put some light into the dark usb port to see if there's any dirt but everything looked quite clean to me. I don't have compressed air with me atm do you think a manual air blower used to clean dslr sensors can also do the job?
any other suggestions if the charger and usb port ( dirty ) is not the case?
Use toothbrush and tiny bit of alcohol ( can be after shave) on it to clean port. Do it when phone it's switched off. It's worth to try.
Did you try different charger?? This can be main problem. Many faulty chargers this days.....

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

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

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

i just bought an extra battery.lets see how it goes.
i noticed my old battery had a small bump in the middle seems bloated. hmm
i remembered last time i used xperia s charger trice,it has 1.5kA it realy charge fast. i think that caused the problem?
when my sister charge her xperia s, the charger just explode.. and she scolded me why am i using her charger.
im using my old charger which is 700ma but it charge just fine. lately when i use the xperia s charger and went back to my old one,it was acting strange. it charges really slow and if i use the phone,it depletes even when charging.
im going to flash another rom,and see if its rom related or the battery isue.
thanks for replying.
ok,im on with my new battery but still depletes while im using it. im just browsing. on the widget it say im currently charging with 1000ma. wierd, dont know how to solve this.
[SYMPTOMS I HAD] it would charge very slowly, if the screen is on, it would actually discharge. When the phone was off, it would slowly charge (i.e. >5 hours to full charge). and it would discharge very quickly (i.e. 1% per 2~3 mins). When the phone was off, it would charge sometimes and sometimes not. Figured that when the phone was off, you really are negating much of the software influences so this could be a hardware issue, however, wanted to make sure before going down the hardware route.
Did some research, searched the forums and searched some more.
I had tried 5 different chargers, 3 different USB cables and had bought a replacement battery.
Steps taken:
1. Cleaned with thick paper - no change
2. Cleaned with thick paper & rubbing alcohol - no change
3. Cleared with Compressed gas - no change (on first charge, there was a change but then back to normal)
4. Attempted to clean with vacuum (with finer nozzle) - no change
5. Used charging apps from playstore - didn't show charging details - considered the port was faulty
6. Tried to find default references for charging as mentioned in one of the forums - unable to find it
7. Found a replacement USB port charger board and replaced it - working fine
So it could be the actual port is faulty. If you symptoms match, it could be time to take it into the service centre, restoring to stock first of course. The note I am using had slow charging for about 2 months prior to really slow charging.
i had change the usb port and its back to normal. 2hrs at least and its full.
Fingers crossed, thats all you need.
I have noticed that when the N6 is on charge, once it reaches 100% and left on charger, the battery starts discharging approx 1% every hour.
I only noticed this when my alarm was going off and when looked at battery usage it was saying 94% but nothing using it - installed GSAM and noticed that once fully charged it starts discharging even while on charge. If I remove charger and re-insert it starts charging again as normal.
Has anyone else noticed this issue. I have contacted Motorola to see what they say, but they are none the wiser and just think it may be a feature of the device/charger but not sure and said to test with another charger.

Not sure, I don't use stock or the stock charger. I would have thought the stock charger trickle charged. I remember my HTC desire used to charge to 100%, discharge to 90 and then charge to 100% in a loop as it didn't trickle charge.
Make sure your using a cable that supports data as well. My stock 5.01 and stock charger/cable does trickle charge.
It's perfectly normal to see this in such devices, though if it were going any lower I'd investigate further.
Maintaining a constant flow to the battery would burn it out so the charge gets it to full and then cuts out, allowing a little discharging and cooling of the battery. Once it gets to certain point, it'll start to juice the battery again.

thanks for the replies - I've not seen it drop below 90%, but I know if remove the charger and plug back in, it will start charging as normal - another thing I have recently noticed is that when you do plug charger in, initially it switches between battery/charger a few times and then starts properly charging - I wonder if this is feature of the phone or lollipop causing this. - other than this phone seems to work fine and have had over 2 days on a full charge
Well got it to drop to 80% while plugged in and it didn't start charging again until pulled cable and put back in
what charger are you using? i leave my n6 on a charger for hours after it hits 100%, and it never ever drops. id even say that when it hits 100% it doesnt stop charging. it keeps charging, with a much less inflow of charge than normal, but its still charging. for about 30min before it stops charging. then it just stays at 100%. sometimes i have it plugged in for 8-10 hours after, never once did it go to 99%. this is while using stock, and custom roms.

The new gen chargers actually cut the power when the battery Actually hits 99% and show it as 100% and stop it charging. But when the 100% drop to 99% (which is not actually visible), it automatically starts charging. But discharging the battery more than 1% is not actually a Normal thing, I should say. I also do charge over-night, never evidenced such thing. I'll suggest you to try with different turbo charger if you have one.
I'm using the stock charger got with the phone. I did contact Motorola over this and they were useless. I know charger works as charges to 100%. But it then just stops.
I have performed a factory reset to see how it goes tonight.
If still no good will speak with CPW and see what they say as don't fancy having to send off based on some of the forum posts
I have no issues with my N4 which has been connected to a power source for days and still shows 100%
I have also noticed that on the N6 when powered off and charge it doesn't show that it is charging
taken it into CPW and they have sent it off for repair - been told 16 days - at least with apple it's near enough same day, shame can't do same with android phones
I had called Motorola uk support and was promised email confirmation of call and also call back this morning regarding the phone and have had neither
back to my Nexus 4 for time being, just hope my Nexus 6 don't come back with any scratches, etc
I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%. I was thinking that it was a characteristic of Qi, but when we got another (identical) Qi pad for the wife's Hammerhead, it "appears" to remain in charging mode indefinitely. Our Qi pads have a blinking white light when they are "charging".
what happens if you just plug the charger directly to the phone so not using the wireless Qi charger, do you get the same fault

Hammerhead does act differently to the shamu. I have both and used them both on the same qi.
Hammerhead trickle charges. Charging icon remains until picked up off charger.
Shamu stops at 100%, charging icon disappears. However, when I remove my Shamu, its always 100% or 99%.. Its never lower.

Good question. But judging by the rest of this thread, I suspect that it will behave the same with a wire as with the Qi. I don't ever actually use the wire to charge, since the ballistic maxx case makes access to the USB plug inconvenient.

I wonder if that could be a coincidence....? I.e., either you aren't leaving it on long enough for the percent to drop lower than that, or leaving it on long enough that it initiates a top-up just before you disconnect it.
Ok, so looking at the DT for the device....
https://android.googlesource.com/ke...ot/dts/apq8084-shamu/apq8084-moto-common.dtsi
Look at lines ranging from 823 to 854 for the smb1357 block.
Note low-voltage-uv = 2750000, max-voltage-uv = 4350000
In mv, that would be 2750 and 4350 respectively. That makes for a range of 1600 mV.
The recharge-thresh-mv = 200
Assuming a *relatively* linear voltage/percentage curve, 200/1600 * 100 = 12.5%. It won't be quite that linear, but this is adequate to give a rough idea of the charge cycle breadth in percentage points.
recharge-thresh-mv accepts values of 50, 100, 200, or 300. The smaller the value is, the tighter the recharge threshold becomes. At 50, we would be looking at roughly 3%.
So my conclusion: working as intended.
There is another aspect that becomes involved when using Qi, which is the bq51021. This one has a parameter "resume-vbatt-mv" set to a value of 4270 mV. That is 80 mV below full, or roughly 5%. Judging by only the name of the parameter, it sounds like it sets a Qi charge cycle breadth of 5%, but I don't understand the relationship between the bq51021 and the smb1357. I suspect that the two have to agree for Qi charging to work.

I don't think so. I put it on the charger at pretty much the same time and take it off at pretty much the same time but starting from different % remaining every day... If it did drop to 90%, i would have caught it at least once by now.
update: whatever you do if you are uk customer and purchased via CPW do not take it back to them - i found out today that they are not accredited repairers and they should have advised me it needed to go to Motorola - now trying to find out what is happening with my phone and when to get it back
I'm still trying to understand how my Nexus 6 works with Qi charging, and the results are a bit inconsistent.
I'm using an LG WCD-100 stand and a BlackBerry Blade charger, both of which are reported to work well with the Nexus 6 (in portrait).
I've had my Nexus 6 on the dock on my desk in work this week, and have been keeping an eye on it. I have the screen on all the time (so I can keep an eye on incoming personal emails). Most of the time the N6 charges to 100%. It then stops charging until it get to about 98%, at which time it starts charging again. So far so good. HOWEVER, on a few occasions it did not start to recharge (even with the battery down to the 70's), and I had to remove it from the charger for a few moments and then put it back before it would start charging again.
I'll try again next week (I'm only desk-bound Tue/Wed/Thu) with a different Qi charger, just in case there's a problem with the one I'm using (though I doubt it).
In the meantime, has anybody seen similar behaviour - or is it time to talk to Motorola UK Support?
the charging issue with it not starting again is the same as what i'm having on wired connection - if you install something like gsam battery monitor you can see that it is discharging while actually charging
I also have the LG WCD-100 (from when I had the LG G3) but not actually using it as I think first time tried you have to get it in the correct area for it to charge
I had problems with my Nokia charger. Because this phone is big and the back of the Nokia was less than half way up the back of the phone, the weight of the too of the phone pushed the bottom of the phone away from the charger.. Imagine the phone as a see saw and the top of the back of the charger as the pivot point. Also the unflat back didn't help
Yesterday after a bit of browsing i connected my charger as battery level reached 2%. To my surprise the charging indicator din't appeared. I opened my battery monitor app to check the problem. It showed AC plugged in and not charging. The tempreature was -30C. After a little research i found out that phone does not charge under 4C. Now my phone is stuck at 1% with charger connected all the time. Since my phone is rooted i can change the value of that limit of 4C to -30C. My question is where can i find this file?
Maybe it's better to see why the temp reading is wrong? So instead of lowering the value in the system fix the temp reading, or that's what I'd do.
I really have no idea where to find the charging temp settings but I have a couple of suggestions, you could try to turn the phone off and see if it charges, or connect a magnetic charger charger, or connect both the magnetic and MicroUSB charger together while the phone is on/off.
Can't think of anything else. Good luck!

I have not done any software changes recently so its most probably a hardware problem. I have tried charging in switch off, its showing the current battery level instead of charging. Perhaps the sensors work even when the phone is off. Tried magnetic charger also, results are same as microusb charger. Changing those value is my last option.

Really??
I didn't know that! I've charged my phone with magnetic charger for some time,(a month, more or less) and it just died.
But it didn't die after using it, it died the moment I connected the magnetic charger.
