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?

why would you want an application to destroy your battery?

Apparently if you do a full discharge the battery life will be longer.

+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?

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

I read that with the new Lithium-Ion batteries it doesn't matter how often you charge your battery. Is it true? Can I charge my battery every day even if I have 80% left without f**king my battery?
Your phone automatically stops charging ~95% specifically to avoid that.
Its actually a better practice for the battery than complete charge/discharge cycles.

i bump charge my device almost daily, on all my devices. never a problem with my battery.
Just got the Note 2, and want to make sure that I treat it really well. I've long been uncertain on the best way to treat batteries. Am I supposed to drain it as closer to 0% and then charge it back to 100%, or is it fine to charge it whenever, even if I'm only down to 62% or something at the end of the day? Seeing as how it's brand new, is there anything I should be doing in the immediate future to properly condition the Note 2's battery? Thanks
You can fully charge the battery drops below 20%.
You can do whatever you want. New batteries technology much better than before

I charge mine every night regardless of percentage (usually around 15% but i sometimes charge over night even at 60%). My battery is still as good as the day i got it.
No need to drain and charge.
Some people say that it reduces the number of cycles of charges the battery can have but it wont make any noticable impact for about 2 years anyway when you're likely to get a new phone anyway, otherwise the cost of a replacement battery is well worth the convenience of charging however you like lol
Sent from my GT-N7100 using xda premium
with lithium ion batteries, you get more overall charges if you charge it before the battery dies.
ie. 100% drain gives you 500 charges
50% drain gives you 1300 charges.
25% drain gives you 2000 charges.
or something like that. also with lithium ion batteries, its bad to completely drain it. when a lithium ion battery is completely drained, it reduces the overall capacity of the battery. most phones have safeguards in place to prevent a complete drain, but leaving a dead battery out for too long without recharging isnt good.
plus, lithium ion batteries dont have the 'memory effect' so draining them fully is pointless. NiCd and NiMH batteries are the ones that lose voltage if not completely discharged regularly.
Dude ... the battery management technology is good in theory. . To understand. ... but in practical use. ..go ahead and charge it as you like. ..the battery will last good for 2-3 yrs... then you can replace the battery. ..note 2 has a replaceable cheap battery unlike the other new devices that are coming out with no option to replace them
Just enjoy :beer:
scribbled from my note 2 (N7100)
You should charge the lithium battery whenever u can, charging more doesnt hurt it really but draining it to 0% is going to hurt it

Since it's Li-ion battery, it's recommended to partially charge whenever you can to preserve the battery longevity and fully charge it from 0% maybe once a month.
so I got Need for speed for my Xperia S (great game by the way, would recommend) the only problem is it is un UTTER battery drain, I'm talking rapid draining even having the screen brightness on low. Do you think the battery is getting damaged by my heavy use in this way? I'm charging it to full, playing it for a good hour and then it needs to be recharged so I plug it in.
cheers

No you are not damaging the battery. Hd games drain your battery. Dont worry it happens with every phone. Please post questions in question and answer section.

How about if I play while the phone is charging, does this affect it in any way, like how with a laptop you should take out the battery if its plugged into the wall to extend the battery's life?

No it wont affect your battery...I have been doing that for the past 10 months

It's a difficult question. From one perspective it's better to keep the phone plugged in because a Li-ion battery has a finite amount of recharging cycles. The worst thing you can do is to completely discharge your battery, then completely charge it again and so on several times. Which is what you've been doing and these are wasted recharge cycles.
But constantly charging your phone will also make it hotter and that combined with an intensive game will make your phone too hot, which might result in some components overheating and a reduced life expectancy.
So I'd advice to keep your phone plugged in if possible, but don't play for hours.
When you compare to laptops, it's indeed better to remove the battery when you're plugged into the wall (keep in mind that the battery doesn't lose its charge though, there's nothing worse for a Li-ion than being completely empty). But there's no phone you can run without a battery so you can't do that . It's also a question of luck. I never remove my laptop's battery and it still easily lasts 2 hours after having it for 2.5 years and using it a LOT (when plugged in mostly). It was just a cheap laptop with a 6 cells battery. Most of my friends that have a laptop that old or older (and also more expensive) can barely keep it charged for more than 10 minutes now.
No,
nowadays you can't damage your battery in any way as I know.
But it is recommended to charge your phone to 100% and turn all notifications off then let it on sleep mode till your Phone is going off by itself.
This doesn't improve the Battery lifetime or something like that but it is recommeded
thanks for the advice everyone
What are the best charging practices to use with the lithium polymer battery that's in the 2014? Given that it takes so long to charge the darn thing having it less than fully changed seems like a huge hassle and a problem just waiting to happen. My laptop has a lithium polymer and from what I've heard it's best to keep it charged around 60% as a full charge or very low charge could hurt the battery life.
I was hoping I could just charge the thing every night and wake up with a full charge, but if it's going to kill my battery life then I'm not sure what I should do.

I charge my 2013 Note 10.1 every night if the battery level is below 65% and if the level is above that I just turn it off till the next day. It has been working for me for 8 months now without issue.

Yea I'm using a family member's 2013 note 10.1 and the battery depletes really quickly. Also if I'm not mistaken the 2013 model uses a lithium ion battery. The new 2014 will be using a lithium polymer.

Maintain charge between 40 and 80 percent to increase the life of lithium ion/polymer batteries.
Haven't used my old Note 10.1 (or my brand new one) too much, but my Note 1, Note 2 and iPad 4 I keep charged constantly and every 2 weeks or so I fully discharge (=use it until it is 10% full). This way I can nearly always take it with me to some forsaken place (without electricity) for many hours. I discharge whenever convenient or when the battery has run below 80-85%. Battery after one year of use is excellent. Do not use this method with crappy chargers on crappy phones as they could overcharge the battery, which is bad for battery life. As an indicator: Your phone should be cold when on charger and battery full.
I found this link that I thought provided some more helpful info on how to deal with your lithium ion/polymer batteries:
