I havent gotten a new phone since 09 Hero.....whats the deal with battery charging. Do I need to fully charge the phone before using it? Do you drain the battery fully before re-charging it?
what give the battery the best life possible?
Never, ever, never, ever, never, never, ever drain a lithium based battery to nothing. Very, very bad. Charge it and keep it above 50% for the firstweek.

Even your Hero should be the same. Most modern cell phones use Lithium Ion which do not have memory effect.
There is no memory for Li-ion batteries so go ahead and just use your phone. You do not have to keep it above or below a certain charge. The phone will not allow the battery to drain to completion so you do not have to worry about that. It is very bad to let a Li-ion battery completely drain but there are fail safe measures implemented in the phone/battery to prevent that. 0% charge on your phone does not mean 0% battery, its just the mA at which your phone thinks the battery has 0% battery remaining.
I wonder if there's going to be a similar procedure to the OG EVO's plug, unplug, turn off, charge, unplug, turn on, turn off, charge method (or whatever it was) to maximize battery life.

Bump charging works for lots of phones to my understanding. Something about how the phone at first doesn't charge to 100% - when it gets to a certain point it just keeps it maintained at that level .
While it is true that lithium ion batteries don’t suffer from “memory” problems such as NiCad batteries they do have a lifespan. For example, the lithium battery in the laptop that I am using right now, and have used for the past year, currently has a 98% charge and is not charging. That’s much, much better than a NiCad battery would be. I can really see the NiCad issue in my rechargeable cordless tools.
But lithium batteries will eventually die. Just ask the first generation iPud owners. Their batteries were failing just after a year of ownership and Apphole wouldn’t do anything about it. They had reached the end of life of their batteries.
Lithium batteries do take a little bit to break in though. You’ll notice a slight improvement as time goes on for the next month. But I would still refrain from draining the battery too much.
Thanks for the input...I too have the hero, and was curios...
...is it Friday yet?
there was a recent article I seen from a link in the g2x forums where they go to actual experts on the lithium who designed the actual cells and ask them how is best to charge them.
the honest answer is for life being your most concern. that means for the battery to keep a consistent charge over the life of the phone without losing actual daily life on the battery,
you have to plug it in when the phone ask at about 20%. then unplug it when the phone says the battery is full. Do not leave the battery plugged in for hours over full. said something about the charge disburst weird or something
anyway it was a link in the g2x forum in general. im sure you can finds it. Ill look if you really want me to,
Lots of info on Li-ion batteries:

Being that the Battery stats are stored on the /Data partition, how is this minimum threshold managed?
One of the worst things you can do to a lithium battery is discharge it completely. They don't suffer from "memory" yet every time someone here in the forums complains that they are getting crappy battery life the instruction to discharge and recharge to 100% before clearing stats pops up.
For those who are interested here is an article that explains in detail.
batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
My main question- Is there some function in android that looks at the maximum depth of discharge level of the battery or is it that most people don't understand the characteristics of L-ion and confuse them with those of Ni-Mh or Ni-Cad?
I want to know because if I need to completely discharge to get better perfomance, despite the reduction in charge cycle lifetime, I will do it but only infrequently.
I've only let my battery discharge completely once, and it wasn't on purpose. From the posts I see here I think I get above average battery life. About 18 hours miui before I go for the charger and on 2.2 roms I'd get 20 hours and still have 40% or so to go. So no I don't think completely discharging your battery does anything for battery life.

I have never run mine down completely. Gotten it to about 6% but that was because I was fighting ROM flashing problems. I usually call 25-30% enough for me and plug in then. I am also getting 30 hours out of my 2.2 with a good deal of use. I used to have a Motorola and their batteries are total crap. If you EVER let it get down below 10%, it took some real work for it to charge correctly and boot up. Even as much as a hardware mod where I have had to cut the wires on a USB charge cord and charge it rigged up with the wires pressed against the battery and prongs in the phone. Very dangerous, but worked for a last resort.
Discharging the battery is not for the sake of the battery,but more so for the ROMs data and how it acquires the battstats usage. I only run it up and down and clear stats when flashing a new ROM, but I do use my phone moderate to heavy daily and have had great success in battery life the way I calibrate it.
The solution I think is to use a larger capacity battery and regulate it to narrower window of operation never fully charging or discharging.
The fastest killer though seems to be heat.
I have read several times that your phone does not fully discharge the battery...that there is still a minimal amount of charge,not enough for the phone to opperate but enough to not damage the battery when it shuts down
Maybe the batterystats file can be saved after being calibrated once and then restored after every wipe oor flash.. that would save some time aabd according to you guys, batt life too
Sent from a cell tower to the XDA server to you.
I've only ever calibrated my a few times and only after flashing a new rom. I never run my battery down after resetting the stats. I just use my phone as I normally do. My understanding of calibration is that it's not about squeezing more life out of the battery despite what most people think but of getting a more accurate measurement of the battery's actual charge. Also while it's true that the phone will shut of before the battery is completely discharged damaging the battery, allowing the battery charge to drop that low shortens your battery's life and decreases the amount of charge your battery can hold.
What gets me is I also read somewhere that for optimum battery life you should keep your battery level somewhere between 70%-40%. Of course that doesn't stop me from charging my phone to 100% everyday. I don't remember where I found that article but I'll post a link if I can find it again.
The reason this bad advice about completely discharging your battery persists is probably the same reason people keep recommending automatic task killers.

Discharging the Battery & Running the Battery Dead is 2 Different things!
We recommend running the battery dead ( Phone Shuts Off ) & recharging while off to train the Android OS from Full > Empty..
Running the Phone until Dead is not Going to hurt the Battery in anyways shape or form despite what you may think or read!
The Reason is, the battery is never fully Discharge & still holds Voltage.. The Calculations of Charged / Dead is at the Kernel Level, so even when dead it still has a 3.4v still or roughly..
As long as the kernel isn't tampered with, discharging the battery via the Phone will never hurt the battery period!
Now, Based on the link you posted you would have to run the battery down past the safe discharge point.. Via some other means of killing the battery, other than using the Phone.
To help ease your mind, Remember this:
~ Charge levels is controlled by the kernel
~ Even when Phone powers off, there is still plenty of charge in the Phone's Battery
~ Battery is never Fully charged, as this also hurts lithium batteries
Roughly every Android kernel does not let lithium battery get below 3.4v and at most 96% charged.
Hope this helps,
~Eugene
If you are still concerned wait until your phone turns off and stick your battery on a meter. You will see there is still power left in it...
My original battery that came with the phone got great life, then couple of months later it was discharging in like 2-4 hrs(froyo), so I called, they sent another one free...5-6 months later that one started doing it as well, so I pulled out the old one from the drawer, it powered on at like 85% ! and I was getting crazy ass life out of it on miui over 30 hrs one time...now that one is acting up again, so I'm going to try to swap again..lol...maybe there's something to not using them for a while...
I've used diff roms and combinations of draining/recharging...calibrating, not calibrating...it's always different results..honestly I don't think there's any rhyme or reason to it other than the fact that many vibrants have diff hardware and there will always be some weird quirk on a per user basis...
As far as hurting it by draining it all the way, I hardly think that's the case seeing as with both batteries I've always let it run down...not on purpose but there has been many many times I've plugged in at 1% or had to power back on because it died...charged it up and got 20-30hrs no prob..usually issues come up when flashing a new rom...
i think it all comes down to luck of the draw. ive had my vibrant since launch day, and i still manage great battery life. my battery is actually stamped 7-02-2010. every 2 weeks or so ill drain the battery completely, turn it back on and allow itself to die again, and finally allow it to fully charge overnight or 4 hours. i usually get a good 7-8 hours of constant use on cm7, or over 24hours if let on standby.
im still debating if i want to grab an epic 4g touch battery as well to increase it even more.

I will edit the post as other suggestions come in.
This is what I am doing and it works very well for me. Keeping all things equal... meaning keeping your screen brightness the same, keeping you live wallpaper if you have it you should see major improvement in battery life.
Draining a new battery to 0 and charging to 100 percent several times will help extend the battery life.
Anker 1930mah I find add 20 percent better life.
I have stock HTC 1 by 1 widgets on my home screen that allow me to easily manage wifi, mobile data, sync and airplane mode. I suggest turning off backround data and auto sync.
New Energy ROM and stock videotron kernel is the best battery life by far and it a awesome Rom.
OC_daemon comes with energy rom.. i use it to drastically reduce your cpu speeds when screen is off and even can reduce when the screen is on if you do not run a lot of widgets / high demand apps...
Let me know how it works for you...

for the last time, lithium ions have been out for over a decade now...they do not have memory so there is no need to cycle these batteries...draining the battery and overcharging it is actually bad for lithium ions...lithium ion batteries must be in a constant state of charge and discharge to extend battery life...draining to 0 and 100 only recalibrates the accuracy of how much battery that your phone shows that is actually left in your battery. also draining the battery and overcharging lithium ions is a very bad idea and will significantly decrease the life of the battery...
the other points are absolutely true and valid and recommended

I never suggest overcharging your battery and battery memory is not the reason for a full charge and discharge.
Fully charging battery helps the phone properly read your battery and use the battery output evenly. The batteries drains at a more constant rate.. I would say it settled down.
According to Anker... to reach the best performance, full charge and discharge your new battery for 4 to 5 times.
I know you do not agree but that is my experience and that is what the maker of the battery suggest. So this should be done.

I know what you're talking about. It's an old mentality that refuses to Die form years of using Ni-Cd batteries. I have a post about this somewhere I just can't find it. search up battery university lithium ion on google. It'll tell you lots more. If this was true all companies with lithium ions would tell you to charge and discharge multiple times...but newer companies like samsung and sony don't even recommend this and they just ell you to charge until full, on many of their products with lith ion now.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life.
there are more articles in other places just got lazy lol

Those test mean very little because in the real world those batteries have to work our phones and not a artificial charge / discharge cycle... Meaning fully charging and discharging you battery allows your phone to properly read your battery and use the battery output evenly.
I would also point out that in that article does not say that a full charge and discharge of only 4 or 5 times will reduce service life. Yes doing this habitually will...

correct...the only thing that cycling a lithium ion does it to read the battery life properly...it will not affect battery life at all, unlike older ni-cd. its a race between getting a longer battery life or a longer runtime...if you want you battery to last...then i suggest you don't charge to 100 percent and you don't let you phone die...if you want more runtime which is what everyone wants, then you have to charge to 100...but as many people notice...going from 80 to 100 takes a long time while going from lets say 20 to 80 takes the same amount of time...also battery drains very quickly from 100 to around 80 percent..
my only point was that you do not need to cycle your battery multiple times. Once time should be enough for you phone to get a good handle on your calibration...besides you can always recalibrate the readout using an app.
If I have lots of widgets, can that suck more battery, also, my network is off all day, turn it on whenever I need it, and sync is off too.

This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.

Enjoy replacing it every year because phone batteries are becoming more commonly HARD GLUED into place. So go ahead, switch the whole phone out.
The issue regarding charging the battery to keep the battery life as long as possible has always been debated for several years. There are many out there who either believe that it's now safe to charge however you want because of the modern technology and safety mechanism implemented on the phone. I still have this uneasiness though, particularly my battery health is about 85% after just one year of usage. I used to charge over night but I have dropped that habit about one or two months ago. Now that my phone is rooted, I wonder if there's a way to set the limit when we're charging the battery so in case I forget to plug it out or I want to leave it overnight but I still don't want it to charge to 100% I can do it.

I just use a budi charger - I set it to charge for an hour as I go to bed. I wake in the morning and my phone's at 80-90% when I wake
Bingo
Edit
This would do the trick
There this Magisk module called IPC "Input Power Control" that basically automatically switches charging off when battery level reaches a certain disable threshold and back on as soon as it drowns to enable threshold.
Look it up here in Github if you want to know more
https://github.com/Magisk-Modules-Repo/IPControl
To all people who helped me, thanks a lot. Now I don't have to worry about charging my phone to 100% anymore if I forget. It works like a charm. 10/10 would customize something else again.
No matter how far battery technology has come, it is STILL a bad practice to keep a phone plugged in over night. The constant trickle charging deteriorates battery faster. Also never fully charge a battery and also never let a battery fully drain.
I charge my phone to 80%
And never let it go below 20%
If you need my sources for proof, let me know.
There are two scientific studies done specifically on this.
