battery charging by itself

I've been using a new original battery for 6 months now, but only yesterday, it seems to be acting very odd, whenever i place My finger on the usb port on the phone, it charges, and sometimes it even charges by itself then stops charging then starts charging again. however i do not believe its charging because the drain is awful as its gone down 10 % in 40 minutes. can someone please help me here. the battery and fine. and I can't check the drain on bbs as it's always charging then not, hence bbs restarts.

may be its time for a new USB charging module.. try cleaning it first...(remove battery first.)

have done, doubt thats the solution, ive noticed, that it only charges by itself when the battery is 40 percent, when the battery drains to ~20% in which it does so very quickly, from 90% to 16% in 90 minutes, the odd charging by itself stops. it may be a rogue battery i guess. going to have to try anker batteries, the originals are not that good.

Sony z1 charge stop at 5%.

Problem started yesterday,phone charge till 5% and than stop,it still says charging but its not.

try to get some battery apps to fix it and try a new cable...

Battery Fix
This is an issue with battery calibration (or so I assume).
What you will need to do is:
Leave the phone for at least 36 hours. Make sure that you keep the phone turned on for as long as possible.
Once you have left it for 36 hours, connect the charger and charge for a whole 10 hours.
Then, turn on the phone and it will possibly show that the battery is at 100%. If not, you need to install an app called CurrentWidget: Battery Monitor. It is available here: https://play.google.com/store/apps/details?id=com.manor.currentwidget
This app will tell you the voltage/current stored in the battery. If the mAh of the battery is 3000 mAh when left charging for 10 hours, then you will need to do this:
Fully charge the battery with the phone for 5 hours and when the phone is fully charged, unplug the charger and turn it off.
When your phone is off, plug it into the charger and let it charge to 100% again. The green LED light will indicate when this is done.
Next unplug the charger, turn on your phone and set the option to ensure that your screen doesn’t turn off, if you have this option. Then reconnect to the charger and wait for it to charge again to 100%.
Once loaded to 100%, unplug the charger again and do not load until the smartphone turns itself off after reaching a 0% battery level. Once off, fully charge it again and it should work properly. The screen setting can put back to normal again (meaning turn off after a certain amount of time).
Hope this helped!

Phone dies at 5%

How can I calibrate my unrooted phone
Sent from my Nexus 6 using XDA Free mobile app

You can't. Even if you are rooted.
Run your battery all the way down until it shuts off. Charge, uninterrupted, until fully charged. Voila! Battery calibrated.
Battery calibrating apps/techniques have been useless for quite some time.

My phone has gone through many charge and shutdown cycles and not even this has changed my 5% shutdown.

Have you tried leaving your phone plugged in after 100%? Let it trickle charge for an hour or two.
The battery 'calibration' stuff that people do is what android does automatically after getting to nearly full charge.
It hasn't been needed since gingerbread.

I have had this issue happen a few times, what I do is plug it in to turn it on , then try to run it down till 0 and then put it on charge while off till its 100% and leave it there for a few hours. Then after a few cycles, this occurs again. I dont charge in the middle, always charge at night until 100% and 30 minutes beyond that.

Battery percentage

I do not understand why the percentage of the battery as soon as I turn on the phone after a full charge immediately indicates 98% and not 100%, even if the display shows off the full charge as soon as I remove the charger.

It's probably because your 100% battery level is nearing on 99% and every reboot, based on my experience, more often than not consumes 1%, maybe more, hence, 98% battery left.

I'd suggest varying how you charge the phone; 1) with the phone on 2) with the phone off
My (albeit anecdotal) experience is that when charged with the phone on, and left on the charger longer than when it says 100%, it's doing a 'trickle' charge, which then seems to charge it completely. Again, anecdotal, but it seems to me that after charging it numerous times with it on, then when I charge it turned off it seems to do a *full* charge.
ymmv

maybe I explained myself badly. in the evening I put the phone off and off. In the morning as soon as I accrue it, instead of marking 100%, it will score 98% .If it is when I unplug it from the charger and it is still off and it is 100% .

Battery drops to 0-1% and other battery problems

Every time when I charge my phone and then I remove the charger, my phone shows that my battery is empty.
It can't be empty if I have charged it almost 3 hours.
And also my phone charges faster than before. When my battery is 1% it takes only 5 minutes to 100%.
I watch my phone, it's 5% then 3 minutes later it's 40% and then it jumps to 70% and so on. And phone was turned off.
I was thinking to calibrate my battery but it's almost impossible.
