I just found this very interesting article, maybe you'll like it too:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Short summary:
1. "A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life."
2. "Higher charge voltages boost capacity but lower cycle life and compromise safety."
its also suggested that you let your phone go through one complete discharge from 100 - 0% at least once a month.
- also on the heat front mentioned in the OP, i take it that means its best to remove your cover when charging your phone to stop a build up of heat?
You mean taking of the case, like Otterbox?
No, I wouldn't do so because my battery never gets warmer than 26-29 degrees.
Bad would be everything above 30°.

Our electronic profs at uni (who actually know what they are talking about) told us to keep the charge between 80% and 30%. Discharging to 0% only harms the battery.
So i'd really like to know where it's suggested that you should discharge to 0% once a month.
btw: This is a quote from the link from the op:
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses."
So i'd say that discharging to 0% once a month is nonsense and only harms your battery
I read that a while ago on the iPhone support website and did that for my old 3g, I just kept the practice running when I got my DHD. I guess either Apple is wrong or its only usefull for non-removable batterirs.

That's probably why their batteries died so fast.
gotta voice in here. i've also heard that its optimal to keep your battery in the 80%-30% range. and that its only damaging to fully drain your battery.
but on the flip side, its kinda needed to do a wipe battery stats once in a while, so i can get a better reading of my battery.... was a time when i hadn't done it for ages, and i was at 1% battery while watching a movie for 30 minutes..
so, I recommend at least, to DONT drain your battery.. but if you are getting really off readings on your battery. do the wipe battery stats thing
My DHD battery seems to be getting worse and not holding its charge. as it's almost been 18 months I decided to buy a new OEM battery and I was jus wondering how should I run the 1st few cycles? And how long will it take to reach its optimum capacity? Also will I need to wipe battery stats and calibrate it?

No Calibration is a hoax, and battery stats are wiped whenever DHD is unplugged with nearly full charge (link to follow from one of the Android devs, don't have it to hand whilst mobile)

I used to worry about battery, then i purchased two of the cheap Ebay ones for like $3 they each hold about a day worth of juice. let the haters hate on the cheap batteries but it's $3! If they are of lower capacity (which must be miniscule because i can't tell) or they die early who cares. Buy a few of them and be done with it.

Why buy many batteries, when you can have 1 quality item?
Cheap batteries can also be a security risk (exploding cell phones e.g.)

how should we go about that? play heaps of games? increase brightness? or do you mean drain it slowly like over a day?

how to charge a new battery?
I still haven't received an answer to my past post. I've just got a new OEM battery and i wanted to know how should i run the first few cycles? is there a certain amount of time i should charge before i unplug it or do i just treat it as i would with a normal used battery?

Suggested initial full charging/discharging cycles are ONLY made to train your phone and NOT your battery and in most cases aren't even intended for current android phones.
Those mythical suggestions are often based on facts for non-lithium rechargable batteries.
Nowadays rechargable lithium batteries are often shipped at least half full. So what you can and should do is just use the battery and try keeping it between 30% and 80%. That's all you have to do.

So are you saying i shouldn't even charge it to 100% and what about the recommended monthly full charge to complete discharge to calibrate the battery?
Well you can charge it to 100% if you want. That will reset the battery log of your phone, so it can't hurt that much.
But charging it for an extensive amount of time will bring you no good. The charging circuit in your phone and in general the charging circuit used to charge lithium-ion batteries will stop charging once the battery is full. That way it prevents the battery from overcharging. But it also means that charging your phone for any more time than it needs to won't make it run any longer.
The monthly complete discharge is not to calibrate your battery as i've allready stated. It is used by the phone to better estimate how much power your battery can currently hold. So in a sense it's used to calibrate but not the battery itself but the battery statistics in your phone.
The phone knows how much energy the wall-charger provides and can thus determin huch much power is stored in the battery once it hits 100% (or better: reaches it's maximum voltage). If you have a charge from 1% to 100% then the phone can obviously determin the battery's capacity more accurately than if you charge it from 50% to 100%.
/edit:
And yes. If you really want to prolong your batteries life then keep it's charge between 80% and 30%.
But just see to it that the charge is above 30% and you're good.

How so? Battery stats is wiped when you unplug the nearly charged phone, so where is this historical data found?

beats me^^
My point was that the calibration is done for the accuracy of the percentage displayed and not to make your battery hold more energy, regardless of what phone/device you use.
And i'm using Battery Monitor Widget so i tend to mean that when i talk about the "historical data". Because BMW really does tell you to run larger charge cycles to increase accuracy. It however doesn't tell you that constantly running your battery down to 0% will only shorten it's lifetime.
How to Stop charging automatically at 80% to get better bettery life?
Like Nissan Leaf Electric car & some Lenovo Laptops.
you get better battery life if you stop charging at 80%?
Yes
Yes
Have you got proof it works this way for this phone ?

It works this way for any device with a Lithium-Ion battery. The battery will last longer in the long term if it's kept between 40% and 80% and charged with small top-up changes. In saying that though, it's unknown whether the benefits of doing this are worth it considering the average life of a smartphone (1-2 years).
meh
It's not entirely accurate:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Life is a function of voltage, temperature AND charge.
Without knowing temperature and voltage stopping at 80% may or may not buy you anything.
For a phone battery it probably doesn't matter.
I don't have a fully automated way to do this, but I use Ampere, which allows you to set a notification on "full charge" (which you can set to whatever you want, mine is 90%). As soon as I hear that notification, I unplug.
That's some ridiculous hogwash...

I use Light manager to set the LED to green when the battery is at 85%. Couple that with @daewond3r 's notification trick and you have manual solution at least.
Hi All
So My default battery died on my Note4 and I got a new one from "Just Battery"
So the difference in the battery is that the default one is 3250mah and the one I replaced it with it a 3400mah
Phone is rooter and running the Hi Vitamin kernal at the moment but is there a place where you can set the battery mah so that when you charge the phone the OS don't stop charging when it reach the 3250mah battery capacity?
How I noticed this is that when you unplug after a full charge it takes the phone 2 min to drop to 97% battery life and then it goes slow from that point. So the OS is definitely not charging the phone 100% full
Install "root essentials# it has an battery kalibration mode..

Battery calibration is just a myth.
I did it on my old phone and there was absolutely no difference between calibration and no calibration.

I'm asking because i bought a Samsung Portable Charger (2.100mah). The Galaxy S4 have a battery with 2.600mah. 2.100 is 80% of 2.600. But the Portable Charger is charging 95%, so i think it's a software problem.
The battery is polled for its vital statistics by the device. The device translates what it receives from the battery's internal circuits to a percentage, which is reflected in the status bar. All battery calibration apps are useless for two reasons. The first reason is they don't recondition the battery. To do so requires expensive hardware, since this is a lithium ion battery we're talking about. The second reason is that they delete the batterystats.bin file within Android. Deleting that file isn't going to do any harm, but that file is deleted upon the battery being fully charged and disconnected from the charger.
Battery calibration is useless. Any positive results are from the placebo effect.

Then let the battery get to 0 and charge to 100. That's the most reasonable method. Any other app just deletes the batterystats, which also gets deleted whenever you unplug the charger from your phone.

Make battery from 100% to 0%. Don't turn on phone until it gets 100% battery. Then use an app called "Battery Calibration" by Miroslav vitulea.
@gosha98_: Draining the battery to zero will not reset the battery. In fact, draining a lithium ion battery to zero is dangerous, as at zero percent charge the battery becomes unstable and may explode. Back in the era of NiCd and NiMH batteries, draining to zero could in fact "reset" the battery, but not today with lithium ion.
Using a battery calibration app prior to removing the battery off charge will not hurt the phone or the battery since all battery calibration apps do is delete the batterystats.bin file in Android. But, it will not help either.

I have been using my phone since 13 July and have been using AccuBattery right from the start. Been charging my phone to 80% amd not to full. Yet the battery capacity is 92% right FROM THE START. I dont think my battery was already 10% degraded right from the start.
What is the stats for other people who are using AccuBattery on their OP5?
What may be causing the discrepancy? Kindly help.
I have the same. Charged from 1% to 100% and above (till charge current went to 0 mAh) and the capacity seems to be 3100 mAh instead of 3300 mAh.
Another thread about AccuBattery crap.
