I have a new Note 2 mpj battery and want to know if it is harmful to the battery if I unplug my charger before charging it to 100%. Is this will shorten the battery life?

Anyone have any ideas why my phone refuses to charge my battery correctly and the wall charger that came with my two spare batteries does a much better job? If I charge my battery through the phones usb I get maybe 5 hours of use but when I use the charger that came with my 2 cheap spare batteries I'll get 8 to ten no matter which battery I use.
Here is my opinion on the situation.

basically it is charging your battery correctly. The problem you are likly having are
1) your battery stats is off and you ahvent recalibrated it so the phone is stopping the charge early
2) you leave the phone plugged in for long periods of time because the phone does not use a trickle charge process it does nto stay at 100% and can acctually be anywhere from 90-100% charged even though the light is green
the reason there is no trickle charge is to try to prolong the life of the battery. the battery stats is to try and help the phone gauge when to shut the phone off and when to stop charging so it doesnt completly drain the battery or over charge it. both have benefits and draw backs.
try recalibrating your battery so that the phone has a better understanding of the acctual life (you may charge the battery fully in the wall charger then put it in the phone wipe battery stats in recovery and the let it drains till the phone shuts off. recharge it fully and go on your way.
the no trickle not a lot you can really do about that.
Guess that makes sense. So you think I should get a full charge from my wall charger then wipe battery stats from my recovery then let it drain 100 % then full charge it and it should recalibrate it?
And thank you for the help.
will charging my battery every night even when battery is only half discharged wreck my battery?
No it won't.
Li-Ion batteries don't have a memory effect and so can be safely topped up.

that was a super quick reply! thanks
Have a Desire Z with an extended Mugen battery. On both CM7 and now Mimicry 1.5 the battery will drain down to 1 or 2% in a fairly linear fashion. The phone will then work fine for quite a few hours more with the battery meter stuck at 1%. Is this an issue with the battery? Or the ROMs?
Most searches for battery calibration bring up mention of removing batterystats.bin....
Charge fully, then drain until it shuts itself off. You are now calibrated.

As detailed by Mugen themselves? Done that numerous times and still the same.
Have done a little more digging and think this might be a battery issue, just ordered a new Anker battery to try. When looking at the stats on battery monitor widget the battery hits 1% at 3405mV. 3 hours later with normal usage it's still at 1% and 3405mV.
Hi
I have bought a new battery of 2430 mah. It will charge complety the first time or does it need to make a battery calibration? If so let me know how i do the baterry calibration
Over the course of months of flashing, I have noticed that my battery life drains really fast. I'm currently running AOKP. I think I calibrated the battery correctly yet I still have terrible battery life. I charged it to 100%, used an app, Battery Calibration, to reset the battery stats, let it drain to 0%, the plugged it back in. The battery said 57% so I charged it back to 100% yet the battery life is still awful. My brightness is at the lowest setting, my WiFi is off, and I am using Greenify to hibernate applications. I've attached pictures of my battery life (from GSam) and pictures of what my software looks like. What is causing the drain? How can I fix it? If anybody can help, I'd be very thankful.
Edit: I have a Hyperion 4200 mAh battery. I replaced the stock battery but it didn't seem to make a difference. The voltage reads at about ~4200 mAh when at 98%.
Edit 2: My battery was at ~60% then I shut it off and plugged it in. It is now at 2%... Should I charge to 100% then reset battery stats?
