Ok this has been happening to me for awhile and i just want to know is this is "normal" or there is something wrong:
Lets say that my phone's battery is under %15 so i plug my cell to charge it....right? so now it has been plugged for a couple of hours and it show that is charging but very slow...and i have to wait like 8 hours to fully charge....but if i reboot my phone let say within 2 hours of charging after it reboot it shows that the battery is fully charge....is this normal?
doubt its normal but mine does the same. Charges for hours and hours but wont go past 85% but with a reboot 100% Same as if I charge it for like 30mins then reboot guess what full charge.
I had this problem at one time, it turned out I had the overclocking set to 528 at all times and this was killing the battery, even when charging. If you have this on, try turning it off. After that it was fine for me

I would like to find out what is the best charging strategy to extend the life of your phone battery. Is is better to use the phone all day and charge at night for 8 hours? Or is it better to plug in while working in the office? Should I not charge the phone that night if I have more than 50% left at the end of the day? Is less charging cycle better for the battery?
Since HTC One does not have replaceable battery, I need to make sure my battery will last at least the 2 years of my contract.
Try to charge as often as possible to keep it topped off. Avoid letting the phone drain completely. However, it has been noted it's good to let the phone completely drain once every month or two to calibrate the battery.
Doesn't really matter what schedule you use, nor does keeping it plugged in hurt any. Whether you charge it starting at 80% or 40% won't make any difference.
Personally I don't want to be plugging/unplugging my phone frequently throughout the day. My method is very simple: I use the phone all day like a normal person, and let it charge overnight on the night stand. The kernel, of course, won't allow the battery to be overcharged from keeping it plugged in all night.
There's a science to all this, but it isn't really worth it!
It has been suggested that Li-Ion (and in this case, Li-poly) remain at half charge for best battery life (about 0% - 60%). Keeping batteries at 100% (in the case of overnight charging) or near 0% (in the case of letting it run out) can be harmful, but you probably won't notice it..
What I do:
-Use the supplied AC adapter and USB cable as each is made specifically to support the One (other AC adapters are clocked in at different voltages and certain USBs don't supply the same power).
-Installed Battery Monitor Widget (or you can install CurrentWidget) to keep an eye on the incoming current (and sometimes outgoing).
-Lately I've been letting my battery drain to 0% to get an initial calibration set up since the phone is new (<4days old). I've been "bump charging" the device:
Go to settings, select power, uncheck fastboot
Let battery drain to 0%
Connect to charger and charge all the way to 100% MAKING SURE that the incoming current is 0 (sometimes it's at 100% but it's still charging)
Shut off device and charge for approx 30min (will turn green, but continue waiting to ensure it maxes out the battery)
unplug, boot phone up, and wait till the phone is fully on, then plug in the charger again
Wait till the LED is green @ 100% and 0 current
Unplug after 0 current and then replug 5 minutes later, waiting again for it to reach 100% and 0 incoming current
Enable fastboot
Do the above maybe once a month? I'm going to do it maybe 1 or 2 more times (only have done it once) this month to ensure proper calibration. Doing this too often will probably damage your battery. Just do it once a month or as many times you feel comfortable. It's a bad idea to keep topping it at 100%
I do the above before I sleep, and as I sleep I just turn on airplane mode, close all running apps, and let it sit there till the morning where I have Tasker set up to disable airplane mode, enable wifi, syncing, and change my ringers 15 minutes before my alarm on the phone goes off.
On normal days (normal charge) I just let it finish the charge BEFORE I sleep, wait till it hits 0mA current and then just pull it off the plug. In the morning I would have only lost 1 or 2% and can get on with my day without worries. Ideally, the battery should remain around 50%. Doing so will probably increase the longevity of its life.
Im having some bad battery problems lately, namely the phone suddenly dying at aprox. 30 percent. sometimes after turning it back on it shows about 15 percent of battery left, then dies again. Fully charging the phone then fully draining it seems not to have solved it til now, I really need some help now! Thanks guys

Found this fix online, see if it works.
Option 2: (No Root) Physical Battery Calibration This option is also very simple, but at the same time, a little more time consuming. If you have a rooted device, Option 1 is definitely the way to go. However, if you don’t know what “root” means, stick with Option 2 and go check out the root section of Android Authority.
Turn your phone on and charge it for 8 hours or more.
Unplug the charger.
Turn your phone off and charge it for one hour.
Unplug the charger.
Turn on the phone and wait 2 minutes.
Turn your phone off and charge it for one hour.
Unplug, turn it on and use as normal. Your battery life should now be a lot better.
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...

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!
How can I calibrate my unrooted phone

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.
I leave phone for charging overnight on 2A charger, but it seems that after it's charged to 100%, current drain continues, since phone is still hot in the morning. If I leave it to be charged at midnight, it should be done in 3 hours max, so there is a lot of time to cool off. This does not seem normal and I did not have it with any other phones. I will try with motorola charger and report.

and its normal if you leave it in the charger all night, it will reach 100%, then drain a little, then charge it back, over and over. oh, and hot, what temperature? battery and CPU temperatures?

Bad signal. App/WiFi/radio scanning for connection.
Just switch the N6 one night in Airplane mode and check if the N6 is hot in the morning.
The problem is that this does not happen every time, but it's definitely not normal.
I leave my N6 plugged in ALL night, and when I unplug it in the morning, it is NOT hot..... So my only guess is that you have some apps running in the background. make sure the camera app isn't running, or any other apps. or better yet, put it in safe mode tonight, and see if you have the same problem tomorrow.
The only time my Nexus 6 is uncomfortably hot is after I play The Simpsons Tapped Out (this also drains, on average, about 20% of my battery within 30-45 minutes...) so I would echo that there may be an app running in the background that is causing the cpu to have issues. Have you checked for wakelocks with something like Better Battery Stats?
