There are lots of myths regarding lithium batteries.. some say you are not supposed to overcharge it (charge it only when it's running out)
Some say it doesn't matter since lithium can be recharged as much as you want and it won't deteroriate the battery's life.
Which one? Can I recharge my Touch Pro 2 every night before I go to bed and leave it until morning? or should I do it when it's running out to preserve the battery's life?
You should keep the device on A/C power as much as possible. So, it's fine to charge daily overnight. Every once in a while, you should let the battery run all the way out before recharging. What this will do is keep your battery meter reading accurate. If you don't do this, eventually, your device will "think" it has more juice than it actually does.

Ah thanks
So to cut the story short, recharge it as much as you can and prevent the battery ever from being run out
Nahhh, not fully true. Somewhere else on the site of batteryuniversity it sais that completely discharging the battery will reset it's memmory. This is usefull after a lot of charges and discharges (in the beginning, I think they already did this (you may hope).
(the memmory helps the battery know where his power is storaged and how much power the battery has left. But doing this frequent speeds up the battery 's lenght of life
In my experience
Enjoy your device and charge battery when needed/desired
Use it normal
Batteries have a duration of 3-4 years aprox, no matter if you charge it every night or leave it till it´s empty...
When battery fails you buy another one and so on
Just my opinion,
My experience with the battery life on my touch pro 2 is that I will keep the phone usually docked in my cradle on my desk when working so it's always on charge. When I use my battery I wait till it's about 40-30% drained and will stick it on the cradle again.
When I'm in my bed ready to sleep, I use the normal charger and leave it on charge over night.
Still experimenting though.

Hmm, first of all Li-ion batteries have NO MEMORY unlike NiCd batteries. You probably refer to resetting the reading gauge - which is related to device's capability of getting accurate reading rather than battery itself. It is recommended to let the device die once a month and give it a full charge to "recalibrate" phone's battery meter (not the battery).
But you should avoid hitting 100% battery mark as well as going bellow 30% as much as possible.
from my experience as a phone shop owner and owner of many many phones i always advise my customers and friends as follows:
1st charge 10-12 hrs. allow battery to fully discharge
2nd charge at least 8 hrs
after 2nd charge you can charge and use as you want. the initial 2 charges kick start everything and starts your battery cycle on good stead
never had any complaints!

The battery should be as cold as possible when charged. So if you are using the phone the battery power drains and is charged at the same time. Therefore it gets warmer than without.
Best for the battery is to be charged when the device is switched off completely.
I wouldn't consider that much of a problem, because you have bought the device to use it and not to live in fear that you treat the battery right
when plugged into USB and playing a game on my TP2 I got the message the device is using too much power, and it drained the battery even though recharging via USB. No problems when using AC adapter though.
Used my XDA Orbit 2 for 2 years now, and mostly charged at free will. Battery is still fine, so no special charging rules for me...
I noticed though, that charging over USB takes quite some time while charging over AC cable is done within an hour or so. When looking at my AC it has 5 Watts of output power, while the USB only has 2.5. That would explain your issue with the battery running out even when having the USB cable plugged in.

Hi!
I'm looking for an application, that quickly kills my battery if it's low, so I can do a full charge to improve battery life.
Something, that I launch, I put my phone on the desk, have a tea meanwhile, and it's drained! Something, that turns on wifi, do some downloading, browsing, video playing, or whatever, and does it automatically without supervision. Does such app exists?
I'll second this, it'd be nice to have an app do this for me and maybe even give us some interesting stats from it?

+1 If you had been reading around...you would know Lithium Ion batteries are designed to 'maximize' their efficiency within about two weeks of 'top up' charging. Cycle-charging is generally considered a less efficient method of charging. You will need to 'TopUp charge' this means charging as much and as often as possible. If your battery is at 89% for instance and you find yourself near a socket, plug your adapter in and charge it up to 100%. After a few days of doing this you will notice an improvement in the life of your battery when you are not able to charge.
Actually,,,
It is not matter of running your battery down to 0%.
It is ok to run it down till phone does to power on itself.
As you know battery is a single cell Li-Ion @ 3.7v
when it is fully charged it's peak voltage is 4.2v
By the time battery mah is drained down (galaxy s has 1500mah)
battery voltage should be around 3.2~3.4v range. this will depend on condition of the battery.
Battery should never go below 3.2v personally, 3.4v is my cut off.
If your battery voltage goes below 3.2v... it's time for a new battery as this kind of voltage will damage your battery, either it will leak or puff (battery will actually get bloated.
Phone has a voltage cut off so it will not over charge over 4.2v but if it does, it will likely start to smoke and catch fire.
I am sure anyone who is into electric Radio control knows all about these batteries.
Oh btw,,, long time storage voltage should be 3.8v
You'll be asking how do I know what voltage my battery is... I personallly don't know of any apps but GPS Status actually shows the temperature & voltage of your battery.

First, take into consideration the comments above regarding deep discharge of your battery...but, to answer your question, there's an app in the market place called 'Battery Refresh' which attempts to drain your battery quicker.
Well if it's all true above than its a good sign, and thanks for the info! I'm not an expert but in the old times I remember batteries had to discharged completely, maybe even if it's just a few times. Now somebody can also tell me why my battery is discharging when it's plugged in the socket with original charger? All I do is using the internet, and has. nimbuzz and a live wallpaper on. :S
You could probably enable the GPS/BT/WIFI ( connected to a router ) and run the interactive mode on Neocore benchmark.. that should enable most of the hardware components on the phone and stress the GPU/CPU.. probably would see a 25% battery drain for every 35-40mins.
I don't know what has changed with the batteries but as far as I know...
it is good to discharge new batteries 3~4 times down until phone does not power on.
Like I have said... it's about the voltage of the battery, not whether battery has any juice left in it or not.
These batteries have a protective circuitry so that it will not charge over 4.2v,
also as for discharge it is usually down to 3v but usually with a charger/discharger units that can control mah/volts/amps. With typical usage from the phone, it'll likely be discharged down to about 3.2`3.4v. Which is very safe.
You can do whatever you feel but I personally do this to every batteries I have for phone and every batteries I use with my radio controled cars.
For my RC cars, I have about 6 batteries ranging from 1cell to 3cell LiPo packs.
Each cell is 3.7volts.
But you don't have to force discharge and hurry the process.
Just use the phone normally and let it run down to nothing... than recharge to full peak.
Than again, choice is yours.
I'm looking for the same kind of applications. It's very useful for recalibrating your battery. Wipe the battery history then do a full cycle.

The old saying in RC Helicopters was that the difference between discharging 50% and 100% was the difference between getting 500 uses and 5 uses.
You should certainly avoid ever fully dischaging any lithium based battery.
Older nickel batteries (Ni-cd, Ni-MH) required full dischage cycles to get rid of memory the the metals pertained, lithium-ion and lithium-ion-polymer not only do not require this; but doing so will damage them.
And yes, the older ipods came with Nimh cells and they did reccomended full discharge cycles.
Im pretty sure the idea was to try not to let the voltage get below 3.5v/cell and never below 3.3. Dead flat is 3 or 2.85 which is when the battery simply cant produce any real current. The phone should have circuitry though to not let the voltage get above 4.25 or below ~3.5.. If the low battery warning comes on, set the brightness to dim, and stop any activities (unless its a phone call, its not THAT important but if youre playing games or watching a movie...) until yo can get to a charger.
By the way this being my first post (i meant to ages ago) Ill just mention that my galaxy S came with recovery mode and download mode Enabled, i got it just last month, Virgin network, Australia.
draining the battery fully was for the older battery types, new age batteries are not recommended to be drained fully
Thanks!
One more question:
I'm using my phone as a desktop replacement, because I don't have Internet at the moment. I'm using xda, dolphin browser and listening music. It's plugged into the mains and it's not charging. It says 49%, and stuck there. Is it possible I'm using too much battery?
Sent from my GT-I9000 using XDA App
Ok, this will be my last reply.
Fully draining or not is not the issue.
In RC, most modern electronic speed controllers have a built-in battery cut-off which will cut off power once it reaches certain voltage. Because OVER-draining battery without cut off can damage/kill/ or make it unable to hold voltage.
Also, once the battery voltage reach certain point (still within safe range) you will notice the motor being powered slow down. This would also be a recommended time to stop.
Cellular phones have built in safe cut off aswell. As I have said I have measured my battery after being full drained, voltage was around 3.55v or so. Which is very normal considering voltage of the battery is 3.7v only with peak charged voltage of 4.2.
Now, Someone mentioned that fully draining your battery repeatedly will dramatically reduce battery life.
Reducing life of the battery has more to do with the amount of AMP used to charge the battery. Faster charging is usually reduce battery life dramatically.
And without hobby grade chargers, you won't be able to control this charge rate.
Slow charge is better but charging at 1C rating is the normal. But charging at 1C means regardless of batteries mah rating, battery can be charged in about 60 minutes. As we all know, our phone batteries doesn't charge from zero to full in 60minutes, right? just like most of the portable devices it takes nearly 3~4hours to fully recharge. Last 20% usually takes longer because Amp provided to charge slowly lowers. That is why.
For example, if Galaxy S battery is 1500mah, than 1C charge rate is @ 1.5amp.
If battery is 3000Mah, 1C is 3.0Amps and so on.
So like I have said over and over before, drain your battery away if you have to by choice or not. Just use it up, I will bet you your battery will last longer than you keep your phone.
U should avoid draining ur battery to 0% (witch is not possible with ur phone. When it shows 0% the charge of the battery is at 10-15%). Li-ion batteries dont have a memory effect, so it would be usless discharching it completely anyhow. Best for sgs battery is charging it before it goes under 50% that will improve the lifetime of ur battery (not how long it lasts before u have to charge but how long it lasts before u have to go and buy a new one)
How do i know? Simply cause i had to learn that a few weeks ago for the job im learning.
@xxgg: yes ur right, it wont really damage the battery if u runn it till thr phone shows its empty. But using an app to drain battery as quick as possible will, since the app forces the battery to give out more Ampere than its built to give out

Used it for a while then it suddenly said the battery was flat and switched off..
Anyone else had this, am I looking at a dead battery or should I just leave it swtiched off and on charge overnight?

It shouldn't be, lithium ion batteries don't have as intense a memory problem as the old nicad batteries...maybe just wipe the batteries stats in clockwork for good measure and take it from there. Sorry I forgot to mention that this would assume you are rooted. All my Android devices have weird jumps like that, but not usually that extreme.
cool, I'll clear the battery stats and see what it says in the morning.
Clear the stats in the morning after the full night charge not before..

Good job I checked here before I went to sleep eh
Lithium batteries do not like to go all the way down to dead (so low the device won't even start). They wear alot if you do. There is no reason to cykle them after the first time charge as there is no memory effect on them.
I had a laptop battery partially charged installed in my laptop and did't use it for two weeks. The battery went compleatly dead and when I charged it I only got like 20% into it before it said full. I had to buy a new battery.
So don't leave your XOOM with 1% battery for a long time. If you are not gonna use it for a prolonged time charge it up to about 75% before leaving it.
SEALen is correct, Lithium batteries should not be fully discharged it significantly shortens their lifespan, there is also no memory effect, the only battery type that ever did have one is NiCad.
The best way to keep a lithium battery healthy is to charge little and often, keep it topped up.

Prolonging battery pack life
Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
Lithium-ion batteries should be kept cool; they may be stored in a refrigerator.
The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.
The rate of degradation of Lithium-ion batteries is also related to battery charge level; they degrade much faster when at 100% charge, than at lower charges. Since batteries die if deep discharged (depleted) and since a battery has some self-discharge it is frequently recommended to store batteries at 40% charge level.

I hope that tells you the answer.
if you leave it @ 0% for any extended period you run the risk of it never taking charge again. i have done this to countless (not phone) batteries by accident and i can tell you that it is 100% true.

I have killed mine a couple times and had a few tense hours trying to get it charging again. So it is best not to let the battery die completely

Thanks for your experience. But android don't have any soft auto turn off phone when battery is 10-15% ?
Besides the main battery power, there is also a reserve power when the battery is discharged. If the reserve is depleted, the battery will be completely discharged and cannot be used at all. Prolonged full discharge of the battery will shorten its working life.

Also, I like to leave my HTC ONE plugged in on my desk stand at work with the "Daydream" clock function running (basically using my phone as a desk clock). Do you think leaving it plugged in charging all day running this clock is doing any damage to my battery? It of course fills up and charges to 100% pretty quickly because I never really let it get below 80%. Below is my charging habit...
1. Charges all night at my bedside
2. Take it off the charger in the morning while getting ready for work and my drive
3. Get to work, plug it in for 6-7 hours running Daydream
4. Take it off the charger and go home... (off the charger for about 4-5 hours in the evening)
5. Go to bed, plug it in, and start all over again...

How To Take Care of Your Smartphone Battery the Right Way
Click to expand...
Click to collapse
Your smartphone is a minor miracle, a pocket-sized computer that can fulfill almost every whim. But none of its superpowers matter a bit if it runs out of juice. With removable batteries becoming more and more rare, you've got to take good care of the one you got. Fortunately, it's not to hard keep the lithium-ion powering your everything machine happy if you follow a few simple rules.
Obviously, the first rule for extending your battery life is not using up all your battery life playing candy crush and walking around with Wi-Fi and GPS enabled when you're not using either and really, really need your phone to last that extra hour. But aside from that, there are some basic rules for care and charging, and they're the simplest baseline for a healthy battery.
Top it off
You may vaguely recall hearing something about rechargeable batteries and the "memory effect." You know, that if you don't "teach" your rechargeable batteries their full potential by taking them from totally full to totally empty, they'll "forget" part of their capacity. Well forget all that. Right now. It's wrong.
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan.
So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent in one go, and then back down whenever possible. A bunch of tiny charges isn't as bad as going from 100 down to zero all the time, but it's not optimal either.
Keep it cool
It's easy to worry about bad charging habits thanks to the training we've had from old rechargeable batteries, but lithium-ion batteries have a worse enemy: heat. Your smartphone's battery will degrade much much faster when it's hot, regardless of whether it's being used or just sitting around doing nothing.
At an average temperature of 32 degrees fahrenheit, a lithium-ion battery will lose six percent of its maximum capacity per year. At 77 degrees, that number jumps to 20 percent, and at 104 degrees it's a whopping 35. Sure, it's not exactly practical (or sane) to keep your phone in the fridge, but it's worth going out of your way to prevent long stays in hot cars and the like.
Avoid wireless charging
Wireless charging is can be incredibly convenient if your phone can do it, but it's not without its disadvantages. The inductive, wireless chargers out there today have this nasty habit of generating a fair bit of waste heat. And while wasted energy is just a bummer in general, that heat will also toast your battery in the process. That's no bueno. It's a little less convenient, but standard plug-in charging is going to keep your battery in better shape, especially if you're some place warm to begin with.
Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.
Don't sweat it too much
It's easy to get protective of your battery, but it's also easy to get lazy. And that's fine, because as long as you're not a complete idiot, you'll be OK. Typically, a lithium-ion battery lasts for three to five years, and chances are you're going to want to swap out your gadgets sometime in that window anyway. The slight damage of a technically bad idea like leaving your phone plugged in all night every night, or using wireless charging, might be worth the convenience.
Still, it's pretty easy to keep your battery reasonably healthy just by avoiding particularly egregious torture like letting your phone discharge from full to zero every single day, or leaving it in a hot car all the time. And the next time you make it back home with power to spare, you'll thank yourself for it.

I dont agree that your battery dosent like being or performs worse at a 100%. Or that it harms the battery in any way. I keep my phone plugged in as much as possible durring the day, and all night long. But i only use the wall charger that came with the phone, or a smart car charger made for my phone. Because as the article says, these chargers are smart enough to stop charging for awile after the phone has reached 100% to prevent over charging/heating. Cheap wall and car chargers dont have this feature and continuously provide a charge to the phone. Also charging using a usb port on a pc or other device does not provide this overgharge protection.
My last phones battery lasted for almost 3 1/2 years before needing to be replaced. Heres what i do.
Keep it charging as much as possible only with a "smart" charger.
Never let the batter drain all the way down. If it gets to 10% and i cant charge it at the moment, i turn it off.
Never let your device get too hot. Dont leave it in hot cars or sitting in the sun, etc.
Never "bump charge". That is just a way to trick a smart charger into overcharging your battery.
Also over clocking/volting your phone puts more strain on your battery than it was intended to take. It makes its temperatures rise higher, and the charge to deplete in a more rapid fassion. Both of which are bad for your battery.
These are just my opinions of course, but it seems to work out good for me. I think 3 1/2 years is a pretty acceptable life span.
never let it die
I have always left my phone's plugged in constantly and never an issue. Once my phone hits 100% it stops charging and then is very cool to the touch from then on.I heard phone's now has a failsafe that will stop charging and start running the phone off the charger and not battery.

What's the best battery conservative rom?
Why do you think you should never fully drain it?
Every 30-40 days, you should fully drain your battery - until your phone automatically powers down - and then fully charge it - and allow it to stay on the charger for 30-40 minutes after it's 100%.

The battery management system in the phone does not allow the cells to go lower than the safe level. For Li-ion cells, that's somewhere around 2.7-3.0volts/cell.
If it did, there'd be not only a huge warranty liability, but also a safety one.

You can believe that if you want to but if you actually read that link you will understand. It puts a lot of strain on the cells to go that far down. There is a physical reaction inside your battery of growing and stretching created from the charge/discharge cycle. If you regularly drop the charge to nothing then it makes it harder for it to keep a charge over time. You're more than welcome to do your method of calibration but I'm a firm believer in keeping the battery healthy.

I didn't say regularly. I said every 30-40 days. I have a lot of experience with lithium cells - both manufacturing and selling.
Before getting the One, I regularly used my HiTec lithium charger on my thunderbolt battery to run a discharge cycle, and then balance/charge it slowly.
No one need be afraid of their phone getting below 10%. It isn't causing any damage.
Well i guess its all a matter of opinion. Me and my wifes first smart phones were the htc incredible. I would never let mine die and the battery lasted fir 3 1/2 years. My wife would let hers die once or twice a month, and it lasted for 14 months before it needed a new battery. Got on her about not letting it die after we replaced the battery, much to my surprise she listened, and the replacement lasted for another 2 1/2 years. Both of our batteries actually still work today just not used to much anymore.
I had the dinc2 and followed the same procedure he used and pretty much nuked a battery from doing that same procedure. In less than a year my battery was bad. To each their own but I still don't suggest running it all the way out.

even anker, who is is probably the biggest portable battery manufacturer recommends not letting their products get below 25% because it can reduce the lifespan of the pack. They state that keeping it between 25-75% is ideal.
Interesting article, thanks for sharing OP.
I also leave my phone plugged in while sitting at my desk and let it charge up. Typically I plug into my laptop via usb while at work, once fully charged it shows 'fully charged' and switches the led status light to green.
I try to never let it die either but have to travel for work and do get very low on occasion, once I get down to 10% I typically just shut to phone off to preserve power while I am flying and avoid turning it back on again til I can get it on a charger.
Battery Life
I'm new to this phone,so I'm not entirely sure how the battery life is ... but I heard a while ago that you get the best battery life out of phones when you only plug them in to charge when they are completely dead. I don't do it often enough to see a difference, but has anybody else done it?
You probably get a much more consistent charge while it is dead/powered off. The only problem there is does letting your phone die occasionally ruin your battery or not?

Did you not read the first message in this thread. wherein it says:
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible.
and
Never go to zero.
Alright, alright - I was merely saying I'd heard a theory stating otherwise.

My laptop, which is a Lenovo, has 2 settings. Best battery health and best battery life. Best health keeps the battery charged to between 50-60 percent and then stops the charge. Best life goes up to 100.
