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.
Hi
I would like to know if the battery in nexus 7 ,how long is it built to last before it wears down & refuses to take any more charge.
is Li-polimer battery in nexus 7 worse than Li-ion battries found in other tabs?
does asus provide post warranty changing of batteries in nexus 7? If so what is the approx cost of installing new batteries

I can answer some of this.
A li-ion battery should deliver 100% of its capacity for the first year, or 250 charge cycles. Loss of capacity would be expected to start somewhere between 300 - 500 cycles.
There are many factors that go into how long until a battery goes until starting to lose capacity. It's all in this article http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Most people are not charging their battery the best way for maximum life. Most people imagine a battery like a bucket of water and think of charge like filling it. But it's not a 'bucket' it's a chemical reaction.
Everyone should read the article above to learn how to get the maximum use of their device's battery.
Yes you can change the battery fairly easily. There are guides that can be found with a web search.
No, there it's no warranty on your battery.
I can't help you with li-ion vs li-po batteries

I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?

Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.
Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.

Hi all,
Today I have purchased Galaxy S5 SM-G900F. The shop sales rep mentioned that, when I'm charging this phone, I have to charge it 6 hours (online charge), even if it's fully charged. They mentioned that that method will improve the battery life. Is it true?
I read somewhere that modern battery doesn't have memory effect. So should I plug my SGS5 G900F 6 hours?

Use it and discharge it under 5% then plug it in to charge it to 100%, that's all. No need for 6 hours charge on S5.

No you shouldn't. Nevertheless most people will tell you to do so anyway. The advice is intended to assure that your battery reaches 100% charge and gives you a good first impression of battery life. It's also stressful to your battery.
Ideally you'd charge to 85%, which is probably 0 - 2 hours charging depending on how much charge your battery has out of the box. Then aim for shallow discharge cycles thereafter. Running to depletion and high temperatures are the worst things that you can do to a lithium ion battery. And charging to 100% is stressful too.
Of course if you want maximum run time and will not be near an charging source, then you will probably charge to 100% anyway. A tradeoff between utility and overall battery life.
There are lots of existing threads on this subject, replete with useful information for anyone that does a search e.g. this or this.

Hello guys. I have a question about battery lifespan. How battery will perform in 2 years with normal usage?
> How battery will perform in 2 years with normal usage?
not as good as today (like every battery)
My only question is...
is the fast charging more harmful for the battery,
Should I expect a faster performance degradation over time because of the fast charge ?
I'm not sure there's enough experience with the fast charging to answer that question for sure, but....
Fast charging generates more heat. More heat means faster degradation for lithium batteries. That's well documented. I personally would only resort to fast charging when I really need it, rather than making it the normal charging method.
If I keep this phone longer than 6 months I would br surprised. Battery should be alright though. I still see old phones running just fine.
