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

What kind of battery time are you guys getting on the original battery?
I've had my phone for about 14 days now and im not getting more than 12 hours on a charge.. the first week iv'e been using the phone alot.
I have alot of apps installed and im wondering if that could have a impact on the battery.. i have tryed using a task killer and without..
From the battery usage statistics page the screen is definitely the one that uses the most. Voice calls is number 2.
Will all applications show on the battery statistics page or is this something the applications have to implement?

My battery has gotten better since I got it. But I have been doing a few things to help my battery - e.g. I completely drain the battery (until the phone doesn't even turn on anymore) and then fully charge it overnight.
Read about task killers and Android here: http://forum.xda-developers.com/showthread.php?t=849974
All apps will show in the battery usage statistics. If the screen has been using the most power, that means exactly that - you've been using the phone a lot and as such the screen has been taking up a lot of power.
I would recommend though to try to completely drain and then overnight charge, and repeat that cycle as often as you can.. I'm no technician, but I do think how you charge the phone matters
i've read about the task killers and have decided to uninstall them compleetly and let android do what it wants.
Regarding the charging, i have ran the battery flat out almost every day..
Im going to try a few different charging methods and see if there is some difference..
however i suspect that if the indicator is saying 100% charge, thats exatcly what it is whatever the charging method. (i hope)
It does get better. When I first got the phone I was getting about 14 hours. Now I'm getting about 30 hours or so.
JuiceDefender and setCPU help preserve battery life, too.
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.
i always thought completly draining a Lithium-ion battery is a bad idea?
Yes, it is.
Older batteries such as Ni-MH should be completely worked out from full to dead in order to keep them going in the long run. Li-ion doesn't need to be worked out, in fact the more it is worked out the faster it will run through it's lifespan and stop holding a charge.
Now that batteries, phones, and chargers are all smart, it's supposedly good to keep them plugged in as often as you can instead of letting them run dry.

The post (#7) above is correct on this. You should not let the battery dip below 30%, since discharging it too low may prevent it from being able to take a charge. It happens to most of us on accident every once in a while. But you should avoid it if possible.
It is good to run through a couple charge/discharge cycles to calibrate the battery meter. Many people still think this is to "condition" the battery, but battery conditioning is only the case with the older NiCad type of rechargeable batteries. Charging/discharging the battery just helps calibrate the battery meter on the phone. For new phones or a new ROM flash, I usually charge the battery to 100%, then let it drain to 30%, and repeat a couple times.

It's also a bad idea to charge a cold Li battery, but I believe that affects lifespan more than charge. For those of us in colder climes, remember to wait for the battery to warm up to room temp before plugging in.
On my DZ I usually get 15~20h of battery life and it's O/C @ 1.4Ghz
3G & wifi : always on
facebook, gmail, emails, news, weather updates each hour
about 1h per day of audio streaming (deezer, Synology DS audio)
1~2h of internet and games per day (baseball superstars, angry birds, psx4droid...)
less than 30min of calls per day and about 20-30 sms...

It depends what you mean by "completely". If you drain the voltage of a LiIon battery too low, you will damage it. But the circuitry of the phone is normally designed that there's a cut-off before you get to this, i.e. "completely" discharging it by running it till the phone turns off will be before this dangerous level, so should be safe.
It's unnecessary though, your phone can tolerate a *lot* more partial discharges/charges than full discharges/charges. If you drain it ten times from 100% to 90% and charge again, then that's roughly equivalent to one whole discharge/charge from 100% to 0% and back again.
As redpoint73 said, the main issues it "training" Android to get the battery calibration right, not conditioning the battery (which only applies to NiMH, NiCad, etc).
Li-Ion batteries are protected from deep discharges in two ways:
1. The Phone, it will stop you from discharging too low.
2. The battery itself. Each Li-Ion battery contains circuitry that stops it from discharging too low.
Basically both have to fail to have you end up with a dead battery -> rarely happens.
Li-Ions take the heaviest duty when charging the top 90-100% charge, charging just that bit stresses the battery more than from 0-80% (ofc 0 not really being 0 ) Note: This only has an effect on battery LIFE, not battery capacity! -> if you keep charging your battery from 90-100% (for example by keeping it plugged in after driving to work, then recharge after driving home, basically always going from 100-90-100 you're really doing your battery a disservice life-cycle wise)
If Li-Ions are not in use for a while they should be stored at around 60-70% charge.
Now as for batteries in Android devices, I'd estimate that most causes of extreme battery drain are due to rampant programs/too many internet accesses.
Everytime you log onto the internet, or change speeds (3G -> Edge-> whatever) you take a lot more power than usual. Try to ensure that all your programs that regularly access the net, do so together (HTC Sense interface tries to do this)
Rampant Programs: Especially services that need to poll the clock a lot, or keep updating their info, keep their FPS high (games) It is for this reason I try to avoid installing a lot of programs at once, and keep it one at a time (especially for system programs) to see if there's a inordinate change in battery life.
Oh and do turn off unneeded things like bluetooth, wifi, and GPS if you don't need them... but thats a given.
Gee typed more than I was planning, just get tired of seeing these threads all over

Sorry but I disagree with that. Have you got any evidence to back that up ? Continually charging the battery from 90% to 100% should be fine and shouldn't shorten its life at all. Chargers will sometimes reduce their charge when the battery is nearly full, and a slower/lesser charge will actually increase its life (I have no idea whether the DZ's charger does this or not).

Coming from the Touch Pro 2 forum, there are somewhat occasional posts by users that discharged their batteries too low, and get stuck in a boot loop. Leaving the battery on the wall charger (USB is not enough) for a long period of time seems to solve the issue in some instances, while others are forced to replace the battery.
As you said, instances of this are relatively rare. I've drained my battery until the phone shuts down plenty of times on accident, with no ill results. But best to play it safe and not do it intentionally.
When you mention the phone prevents the battery from discharging too low, is that the hardware, or the OS? I guess either way, maybe the Desire Z or the Android OS are better at this then Windows Mobile and the Touch Pro 2. But I still wouldn't discharge the battery too low intentionally.
I'm pretty sure on the Touch Pro 2 it was software based (hence actually allowing you to boot before saying "not enough charge" )
I doubt that ANY charger that comes with a phone is anything but a normal "charge till full" charger...

Are you using it pretty heavily? I just got the phone Tuesday, and still playing with it a lot, so I can't comment on battery life yet. But what is your screen brightness set to? If you look at the battery use graph, you will see that the display uses the most power, and with any smartphone, the biggest culprit of short battery life. Turn the brightness as low as you can tolerate for your "average" viewing conditions. Also, be sure you've calibrated the battery meter as I've described in Post #8 above.
A word of caution as far as the Mugen extended battaries: one of the users here did a bunch of battary tests on OEM and different aftermarket brands, on various phones. The Mugen 1800 mAh batteries did not rate any better than the OEM 1400 mAh. Mugen tried to explain away the test results. But judge for yourself.
http://forum.xda-developers.com/showthread.php?t=583927
My screen brightness is just 25 or 45%. And i really don't make it to the end of the day.
I now have setcpu, so that when my screen is off my cpu is running on 300mhz. Think i can make it now through the day.
I use my phone a lot, thats true. But only to view the market or twitter things..
Ow and i don't use live wallpapers...
I think there is a lot to be said for keeping things turned off if you do not use/need them too much.
I leave my phone charging overnight (between 11pm and 6:30am). So when I leave the house in the morning it is fully charged.
I keep Wifi and 3G turned off unless I need to use it and I keep brightness to a minimum - again, only increasing it if I need it.
Normal usage for me would be about 1 hours music listening during my commute to work, a couple of texts a day and about 10mins worth of calls a day.
On top of that about 4 hours worth of data use (both Wifi and 3G) and I usually find I still have over 50% battery life left when I plug it back in around 11pm before going to bed (according to the Mini Info widget).
Granted this is fairly light use compared to some people, but I think if you take the time to control your app usage you should see better performance results!
I just got some new batteries for my i-9000. I am wondering, I have always heard LIthium batteries do not like to be fully discharged. I want to perform a calibration on the new battery, but all the battery calibration apps say
1.Fully charge the battery
2.Press calibrate battery button.
3.Run the phone fully flat until the battery dies.
4.Fully charge the battery to 100% uninterrupted.
Now, step 3, going all the way until the phone dies, is that a good thing to do or a bad thing to a new battery?
Letting your cellphone's battery drain until the phone dies is a normal thing that won't damage your battery, because the battery won't really go to 0% charge.
Cellphones always shutdown it-self when the battery levels get too low (like 3%), to avoid the damage it would do in the Li-ion battery if it would go to 0%. So you have nothing to worry about.
yeah mine shuts down around 2-3% percent for that reason. You'll be fine.
thanks.
.
just doing it once when you get a new phone or after noticing horrible battery life on a newly flashed ROM can work wonders
other than those times, I only let my phone get to 20-40% before I plug it back in
I Use BOS Gingersense Port From Kingdom, My battery is good and i didnt do that whole discharging,recharging crap.
calibration works for me...
Calibration even worked for me too, on my Galaxy 3. Previously i was getting backup of only 1 day, but after calibration i get around 1.5 days. I know its not much improvement, but still its worth.
And you don't need calibrate frequently. Just once in two weeks is fine. And I've heard that deep discharge once a while is infact good for the battery. Correct me if I'm wrong.
waiting for phone to completely die right now. One question though can I turn on phone while charging or should I just leave it off after dieing?
I called Sammy, they told me letting the phone turn off by itself because the battery can't power it is bad for the battery in the long run, they said you can't really see the bad effect that time, they told me, we have learned on are testing that when you see the low battery message pop up that is where you need to charge the phone, that warning is where the calibration starts, now draining it to the point that the phone turn itself off is bad for the battery. Do you believe that?

Only if you leave the cell empty.
It's best to recharge a cell as soon as possible if you have discharged it.
Discharge/charge cycles should be kept to a minimum, ie when you first get the battery, when you are sure you need to recalibrate, and when you've got no choice.
Top up charges are best for lithium batteries.
The charging circuitry in the phone should protect the battery from over discharge. It also protects the phone from overcharging. However, just like a spring, it's the constant charge/discharge that damages a battery. I would not run it down every day but it should not damage the battery, only cause it to wear out faster.
Source: I'm an electrical engineer.
Try to avoid frequent full discharges. Occasional full discharges are okay.
Lots of uncertainty here, lol.
A new Li-Ion cell will output ~4.2V when fully charged and ~3V when it is totally discharged. Every single smartphone I've owned would shut down before the cell dropped below 3.5V. Draining your phone's battery until it dies will not hurt the battery or your phone. No worries about batteries catching fire.
Repeated or frequent full discharges will wear your battery out much faster, though.
I recently bought a S4 Mini (i9195) and I noticed it has a decent battery life.. until 5%. When the battery reaches 5% I get a huuuge drain.. it's like, draining to 0% in about 1 minute. And it happend all the time. Whats wrong with the device? :crying:
I'll try that, haven't noticed what happens at 5%.
Im shure mine has 3%/hour battery drain over night so I'll spect from 5% at least one hour at idle

Doesn't happen to me but I've experienced that with my old phones. Always happens when I charge my phone when it's far from empty and unplug it when it's far from full, multiple times.
Like I used to plug it in whenever I could find a power source so that I can play my games throughout the day. And I usually have to leave halfway for other things so I'll unplug it when it isn't fully charged yet.
Then after a while I noticed that the battery was draining quickly when it was at lower percentages but draining slower at higher percentages.
It slowly became more constant as I learnt to charge it when it was completely dead and unplug it only when it was full. (I bought an external battery pack USB charger to help with this)
I think this calls "memory effect" or?
Lithium batteries do not have memory effects anymore.
If the phone is new, try charging it completely and discharge it completely a few times. If it then still persists, the battery is probably not calibrated right.
The real size of a battery is not as stated on the cover 1900, but varies around it, depending on the manufacturing. Similar to CPUs, that get tested and then categorized for certain speeds.
So could be that you have a less optimal battery and therefore the calibration to 1900 as expected by the system is not right. So when you see 5% you are already much lower in reality.
I am new to Android, so I do not know if there are battery calibration tools out there, but I guess so.

Sent from my GT-I9195 using xda app-developers app
Nope, the system will just shut down at about 5% to prevent a deep discharge of the battery which is really bad for li-poly/li-ion batteries.
So I've noticed some weird battery behavior on my Pixel 2 XL and was wondering if anyone else has noticed this.
I normally like to ;et the battery drain down into 5% or so before plugging it in and letting it charge through to 100%. I started noticing that a full charge would take me nearly 2 hours fully charge. A couple of times last week, I had to step out and the phone was charged approximately 95%. I unplugged the charger and walked to my car (about 5-6 minutes to get to the car) and when I looked at my phone, charge had dropped to 88%. Over the next few days I noticed this kind of excessive drain immediately after unplugging the charger. Aside from this, I still achieve 24+ hrs of battery life on a single charge so I am not sure that it is a HUGE issue, but one I felt shouldn't be happening nonetheless. Last night the same happened - unplugged around 95% and i literally saw the battery indicator go to 93%, 91%, 88% and then stop at 87% in about a minute. I immediately called Google support, shared my screen, and after speaking with the person on the phone - i was told I should definitely RMA, which i did..so I have a replacement coming.
I don't use always on display or always listening and I am extremely good at clearing open apps before I put the screen to sleep. I have noticed this at home, on my wifi as i always need a charge later in the day when I'm home from work. Also, I use the OEM charging wire and brick.
Anyone else notice this ?
I have not noticed battery drain fast after unplugging at full charge level. I would say you probably should RMA the device. Also it is not good to let lithium-ion batteries go down to low levels a lot like that, it will degrade the battery faster. The less you let the battery go down to low levels, the more charge cycles you will have, which means long battery life over time.

I definitely did RMA, it was a painless process.
And I always thought that maximizing the charge of the phone (letting it get low, then charging up) would actually keep the battery healthier as it would reduce the # of times I charged it. Am i way off base with my logic for that?!
Going into my third week with my 2 XL and I haven't seen anything abnormal regarding battery drain.
I do practice the method of unplugging at 85% and plugging back in around 15% (per Accubattery's reco, and other reading done online)....
There's no proof that it helps as suggested, and while I realize that only allows me access to 70% of the battery's charge potential, I'm rarely, if ever, away from a plug for more than half a day.
This theory worked well in my 6P until it got the intermittent BLOD... My battery health was around 84% (via Accubattery) after 17 months of pretty heavy use.
Again, not sure it is solid fact or not, but you could always try it for a month and see if there is any noticeable difference in battery drain.
Thank you for that insight! I will absolutely do some research. You're battery health after 17 months is really impressive. I just switched from a Nexus 6p that was definitely showing signs of wear after 2 years of fairly standard use. I hadn't used accubattery, but I will download it on my new replacement and monitor results.
I will say though, that aside from that slight blip i noticed - the battery (andOS optimization i'm assuming) is amazing. I get through a day plus easily. So, anything I can do to keep that consistent or squeeze more time out of it is a no brainer.

This theory worked well in my 6P until it got the intermittent BLOD... My battery health was around 84% (via Accubattery) after 17 months of pretty heavy use.
Again, not sure it is solid fact or not, but you could always try it for a month and see if there is any noticeable difference in battery drain.

I definitely did RMA, it was a painless process.
And I always thought that maximizing the charge of the phone (letting it get low, then charging up) would actually keep the battery healthier as it would reduce the # of times I charged it. Am i way off base with my logic for that?!

Lithium-ion batteries work on charge cycles and are happier between 50-85% charge levels. You cannot really "overcharge" the battery because the phone will stop charging at 100% and just trickle charge to keep the battery at this level. But unplugging it after full charge defiantly wont hurt. If you keep the battery at higher levels I would't be surprised that you would get 1500+ charge cycl.es out of the phone before any real degradation which should easily get you years of good battery life. I find the battery life on the XL to be awesome and it lasts me throughout the day with still 40% battery life left and that is with pretty heavy usage.
