Is anyone else having a problem with the touch pro 2 not charging fully when it is off. I have the Tilt2 and have tried many different ROMs. For whatever reason if i charge the phone while it is off, it only charges to around 96% or less. I do have the 1% battery driver installed and i can not figure out for the life of me why it will not fully charge. If i leave the phone on, it charges to 100% but at some point i get a message telling me it disconnected from the connection. Can anyone help. Thanx
Same issue :-(
me too. Same problem
There's been several threads on this. The general consensus is the battery stops charging when it reaches 100%, and then begins to discharge. I've noticed the same behavior but haven't found a fix.
Very odd
The weird thing is that I have charged my phone while it is off and one morning I wake up and turn it on and it is at 91% then the next morning it will be at 100% then the next morning itll be 86%. I usually turn it off around the same time and turn it on around the same time. I cant see it starting to discharge if there is only an hour possible time difference. REALLY annoying lol
Icon issue with charging and Battery level
I have an odd issue. I am running the stock ATT rom until I can get the stupid phone to take the HardSPL (different issue being worked on).
The icon at the top shows the battery at full capacitiy all the time. I have Phone alarm on and it has a battery indicator that shows it as low as 20% while battery icon is still 4 bars full. Also there are times when I remove it from the usb and the charging icon stays on instead of showing the battery icon. If I soft reset then it seems to go to normal and the charging icon is replaced by battery which seems to always show full.
I've seen a few post regarding the 4.3V at 100% thing, but they're too old and haven't really given me much information.
My main issue is that I'm experiencing unusually rapid battery drops after my phone reaches 12% charge, it'd drop to 0% in just a few seconds. I downloaded a few battery calibration apps thinking that it might be a calibration issue. In that process, I noticed that the voltage read by these apps (and even in the *#*#4636#*#* menu) when fully charge is 4,38 volts. It was my understanding that Li-Po batteries should be fully charged at 4.2 volts and that charging past that point is harmful for the battery.
I also noticed that if at this point (charged at 4.38 volts - 100%) I unplugg the charger, the battery indicator would show 100% for a while, until the voltage drops below 4.2V, at that point the porcentage would change to 99%, so it seems that the device is set recognize 4,2V as fully charge, but it continues charging after that point. Also, the green light turns on at 90%, is this normal?
I tried calibrating using this app but with no results. I'm trying the manual calibration now. What is going on here? Could this be a clibration issue or do I have a faulty battery?
I think it is not normal. My P6 drops even a little bit slower from 10%. current my P6 is on 6% and 3,627V. (Edit: Turn off: 3,55V / After charge 100%: 4,32V)
Next time i will charge, then i post the Voltage at 100% for you.
To calibrate the accu you don't need any app. Use P6 until it is automatic power off. Now turn it on so often until it will not start anymore, and only show a red accu on screen. Now charge to 100%, turn on, unplug charger. Now your accu is calibrated.

Thanks, heross. So apparently the >4.2V @ 100% is not so unusual. Does your phone remain at 100% for a relatively long time and drops to 99 after the voltage is below 4.2V? Mine does that, and it also turns the led green when it reaches 90%.
I'm sure the dropping from 12% o 0% in seconds cannot be normal, but I'm wondering if the above is a symptom that something is wrong or
if it's normal.
EDIT: Ok, the phone just turned off by itself, the quick drop hapenned as usual (12% to 0% in less than a minute) and the voltage fluctuated between 3,1 and 3,3 volts in the process, maybe even less than 3.1 V, but I'm not sure. I took a series of screen shots 2 seconds apart, I'll post them when I turn the phone on again, I'll let it charge as you suggested.
Yes LED green at 90% is normal. My P6 drops to 99% after 1-2minutes screen on or after a boot without charger.
12% to 0% in seconds is definitely not normal. Normal it goes down very slowly to 3% then it comes a Info and after 30sec it power off.

Finished charging.
I've turned the phone on and it has been sitting at 100% for about 25 minutes at 4,348V with the screen on. (I even played a video with full brightess). After that it droped to 99% and 4,079V[/B]. That can't be normal.
I saw that the P6 battery is rated 4,35 volts, so i'm not too worried anymore abut that voltage and everyone else seems to have the same values, but this quick drop with 12% and the fact that it stays for so long at 100% does worries me.
The screenshots were taken 2 or 3 seconds apart. It doesn't give me a low battery warning at 15% like most phones, but at 8%
I'm still having this extremely annoying problem. The goddamn battery goes from 12-13% to 0% in a blink of an eye. I just plugged the charger at 8% and it show 0% right after and started charging from there. Voltages are strange too, it shows ~3,6 volts when it started dropping quickly. It has charged ~20% in less than ten minutes. Look at this behavior: sudden voltage drops, never went below 3,3V and dies at 3,6V (almost nominal voltage)
I've tried calibrating several with several methods a few times, I'd prefer to stop doing that since I know it stresses the battery.
Has anyone had this issue? Can someone please shed some light on WTH is wrong with this troublesome phone?
Saw this post now. I have the same problem but it is from 9% to 0% . I don't think it is the battery, i think it is how android reads your battery info. I managed to calibrate mine by charging it when off from 0% to 100%-didn't last for long, the problem appeared once again.
It stays to much at 100% after charging, so we have the same battery life. Might be the kernel, don't know. I home when emui 3.0 is relased comes with a new kernel as well.

I also managed to fix it once, I don't remember exactly what I did (I've tried so many things) but it didn't last long either, it discharged normally one time, but the next time dropped from 12% to 0% again in seconds. When will EMUI 3.0 be released?
They said emui 3.0 will be released in the middle of november for p6 but they also said that it will be available for p7 since october -they kept their word and it is available but only for the chinese versions of p7. So i would expect emui 3.0 for p6 in december for the international version.

Ok, I think I managed to calibrate it, I'm not sure yet, I will update once the battery is drained so I can see how it behaves at low charge, but there are indications that it's working.
If you're experiencing the same problem as me, then you've probably noticed that after your phone drops quickly from 9% (in your case) to 0% and you plug the charger, the battery will charge up to 9% also very quickly. If this happens, then Android is not reading the battery info right and you'll get a 100% reading before it's actually fully charged, and will keep on charging past that point (which I believe is why it stays at 100% for such a long time). It'll obviously drain from 9% to 0% again once it's discharged - because it's not really at 9%, it's much lower.
So, if we can manage to get Android to display normal charging speeds at low charge, then the battery should be calibrated. This is what I've managed to do.
Here's how:
1. Get a Battery Monitoring App (I use Battery Monitor Widget) and set the update intervals to 1 minute
2. Let your battery drain and your phone turn irself off until you can't turn it on
3. Plug the charger and turn the phone on. Watch how the charge increases in this process, it'll most likely charge too quickly (See graph screenshot - blue arrow: a steep slope indicates quick, abnormal charging speed readings)
4. Wait 5 minutes or until it reaches 10-12%
5. Unplug the charger and let the battery drain again. Watch how it discharges, if it charged too quickly in step 3, it'll most likely discharge quickly too here (You can see in the graph screenshot that the discharging slope in this process is also very steep)
6. When it says it's going to turn itself off in 30 seconds, plug in the charger (don't let it turn off).
7. If the 'turning off' message appeared, say, at 2%, your phone will probably display 0% after you plug the charger (i know this makes no sense, but it happens like that)
8. Let it charge and watch how it's charging.
After doing this my battery charged at a normal rate (Graph screenshot - red arrow) and it behaved normally approaching full charge (current started decreasing approaching 100% - green arrow). It didn't stay for ages in 100% after unplugging the charger either, just 1 hour in deep sleep (2nd and 3rd screenshots), which I think is fine because I used to unplugg the charger at night and wake up to a 100% battery, so it seems Android is reading battery info correctly now.
I hope this works for you too, mate (And that it will last more than one charge cycle).
I'll update tonight with low charge behaviour, but I'm pretty sure it'll discharge normally.
EDIT: It didn't actually eliminate the problem, but it got a little better, it now drops from 7% to 4% (instead of 12-13%) and stays at 4 for a while.
I charge my Nexus 5X with the official charger, and usually takes less than 2 hours to charge (not sure if 1h30m or 1h40m I don't pay attention tbh), and normally it charges this fast. Except in one situation: When the phone is turned on charging after turning itselff off reaching 0 battery (I was just doing a full charge 1 time).
In this situation, the N5X still says "charging rápidly" but it charges 1 battery every 2-3 minutes, and says "4h left to full charge". I let it charging turned on like this, and this slow charging continues on and on... and it really takes that time to charge.
However, if at any point I turn off the N5X and I let it charge for a little turned off, it charges normally (1 percent per minute or more) and after turning it back on again, it continues charging normally.
This is strange, and didn't happen with the N5.
Any of you noticed this?
Previously coming from S8 & Note 8, while playing power demanding games plugged in it would hold and charges just fine but now it's barely gaining any. It says "fastcharge" but doesn't feel like it at all... anyone having similar issue?
I been on 4% past 30mins or so while playing Lineage 2 Revolution. Sometimes, I would lose 1~2%!
I have the same issue. I am charging S9 via cable with quick charge 3.0 adapter in my car. Some times it charging fast but sometimes it discharging even in idle. I found that it can be related with phone heatup. In sunny weather phone is warm (battery temperature about 40C-42C) and phone not charging. If I put phone in shade then it start charging in 5 minutes
Very odd ever since the phone died since it was really cold out ( i left it in car for a few seconds and looked at my phone and it was dead ) its been shuting off or dieing around 10% left but drains normally. but can still turn it back on once its plugged into a wall charger. so im not sure on what to do cause i mean i only had it for a year now.
it happens with mine too, 2-3 weeks ago.
I had 40%+ and after few sec, was dead too.
I turn it on with 1% battery lol
was thinking of letting it die once then letting it cable charge not fast charge saw a video for an older phone to do that with some call code to reset the battery gauge

I have the same problem since a few weeks.
The percentage drops from 15% to zero.
Mine was a bit different, I was in 13% and then when I plugged in the cable to charge my phone, it showed I was actually in 6%. My friends, our phone is aging
Since it became cold outside I'm having the same problem
Yes
I had this problem with my Galaxy A5 2016 and now with my Galaxy S9...
Never go under 10% if you can't charge within 1 minute or better less. That's why I have a battery case.
So I think I fixed mine a video is for a note 4 ut I think it worked for mine also. Make sure your phone is almost dead and turn off fast charging then go to the phone dial up (built in app) and dial *#0228# and click the quick start (this will restart your battery gauge) let it die then charge to full might take longer but it's worth it.
