[IDEA] Charge button

Is it possible to make a small program that allows to toggle charge on and off ?
as far as i know...charging our Diamond isnt nothing positive toward battery life .
I know you can enable or disable charging in system/power
but it would be awesome if someone would write small program/script to do that so we can place shortcut in programs menu to toggle

There is a setting that allows you to chose to charge or not to charge when synced.

As far as I know... it doesn't matter with actual batteries.
If I look at my notebook (which is over 2 years old) where I charge and uncharge all the time - the battery works still fine.
I'm not sure if it's worth the work - if the battery life sucks after a few month (years..?) - you just buy a new one for a few Euro/Dollar. (Man! You don't have an iPhone...lol)
I've never had a mobile phone for more than a year - so I wouldn't care!
(But I'm pretty sure the actual batterys don't care either!)

Li-Ion batteries don't suffer from the memory effect in the same way as Ni-MH batteries do, so theoretically it won't harm to charge the battery whenever you want to, regardless of it's charge level at the time. They do have a limited amount of cycles though, a cycle is when it goes from full charge to full discharge. It's eventually going to wear out no matter how you treat it.

so basically what your saying is Li-Ion batteries cannot over charge and then eventually start to decrease in total battery life?
If so, does that mean my T-mobile Wing's battery just crazy?

It would have exploded if it could "overcharge".

li-ion has a limited battery life by itself, which doesn't depend on usage/charging.
but charging can shorten the battery life if done wrong. charging cycles vary depending on how empty the battery was. it looks something like this: (see wikipedia/google for specific numbers)
95% 1000000 cycles
90% 100000 cycles
70% 10000 cycles
50% 1000 cycles
30% 100 cycles
10% 10 cycles
0% 0 cycles
actually you can never reach below 30% because the battery or phone will protect itself whenever that point is reached and turn itself off.
conclusion: charge whenever you can!
ps: li-ion for cars only discharge to 70%, so the battery can actually be used for longer than 2 years unlike a cell phone battery, where it can be discharged to 30%.

Guys, this is silly. The battery will work with no problems for 2-3 years. Then you can buy another one or, more probably, another phone. There is no point whatsoever to not charging it when connected to the computer. As a matter of fact, this will only reduce its lifetime.

Prolonged Battery Charging ~ Yes, I believe it is Safe

Prior to getting the Galaxy S, after I read what Samsung were saying in the manual of not to overcharge, I investigated the reasons and wrote in various topics on the battery and the differences between Li-Ion & Li-Pol battery types.
At that point with all the evidence found it made sense to believe that what Samsung were saying in not to overcharge was accurate.
Basically, at that time it was believed the phone used a Li-Pol, Li-Pol batteries are different in that they are 'wet cell' as opposed to Li-Ion which are 'dry cell' charged.
Li-Pol can be manufactured much thinner but can not be manufactured in different shapes.
This is to allow the wet cells whilst under charge which become hot to move around the battery freely. If a Li-Pol was manufactured in different shapes like Li-Ion it would create a 'hot-spot' in an area where the wet cell could not move fluidly around the remainder of the battery.
However, it has now come to light that this is not the case and that the batteries provided with the phone are indeed Li-Ion.
Anyway, moving on to the present.......
After now getting the phone and doing a bit of testing I have found the overcharging issue NOT to be an issue.
When you commence a charge on the phone the icon changes to a charge state.
However, once the battery has reached maximum charge capacity the battery icon automatically changes to a 'Non-Charge' state and then the phone simply runs off it's own battery. This is despite the phone is still connected to the charger.... It's just that the charger although still attached is no longer charging the battery.
As soon as the battery falls below a certain figure (I've had different figures ranging from 98% right down to 91% which is probably due to whatever the phone is doing at that particular time to wake the phone up from realizing "hey, you are still attached to a charger, now wake up and start charging again").
So to all of us who have been worried about overcharging, my personal advise is to NOT worry and charge as and when you feel the need.
Hope this helps.
Beards

Thanks for clear up, I was always been scared while charging that it may blow up.

Nice find!

When you say "it has come to light", what do you mean? Is it just your deduction from your battery tests, or did you see this info from Samsung?
From what I understood, the LI-Pol overcharging is an issue in theory, but in real life applications its not a problem as long as you use the charger that is designed with LiPol in mind, it will auto shutoff charging once it senses the battery is full.

I have just charged mine from bone empty to full. A notification came up stating that the battery was full and to disconnect the charger. Although the battery monitor app says it is not charging and the normal battery meter has gone solid.
I agree that it seems to stop the charging circuit. Although I thought we were getting LiPo not li ion for these as well it's definitely li ion though.

Take the battery out and turn it over. Now read the battery type and you will see it says Li-Ion.

if such, it will reduce the re-charge cycle....
i suggest, power off the phone and then keep charge overnight will be safe....
otherwise, if it is on and charges only full then disconnect it

Modern battery's don't have cycles where you loose power by continuously topping up the battery.
The practice I use is I charge whenever I get the chance, then after around 30 charges I run it right down and do a full charge.
As to powering off the phone to charge, this is not always convenient.
I need my phone on all the time in case I get an emergency call-out and I'm sure there are others who need their phones on overnight to use as a morning alarm.
Finally, I'm not sure if the practice you mention in powering off the phone and charging overnight would have the same effect in being able to re-charge when the battery level drops.
I think doing it in your method the charger would continuously hit the battery regardless as to whether or not it is fully charged ~ which in effect is what Samsung are saying in not to overcharge.

To me it seems like the phone will NOT use the battery as long as it is plugged in. On my phone the battery meter never drops under 100 % when connected.

AFAIK, the reason to fully deplete the battery is to properly calibrate the % remaining in your battery. Running your battery down to empty causes more stress to the phone than running it down 50%. I happened to get a free battery with my device, but I would've bought a spare if I didn't get a free one, so I can easily go 3-5 days depending on usage, during this time I have my house and work to do charges. However, let's say I were to be expecting to have less frequent charges, such as taking a vacation, prior to that I would be fully depleting the battery to 0% to calibrate because then the battery level is more important to me. The trade off of long-term life vs short term accuracy is a very easy decision for me to make due to my situation.
In older batteries you had to "use the cells or lose them" situation where it was better, to at least occasionally, completely run down the device rather than doing partial cycles. These days, charging @ 50% 2 times is equivalent to 1 cycle of 100% with less long-term "stress" to the battery.

Same for me.

The reason it tells you to unplug the charger when done charging has nothing to do with battery. It is to save power. Battery chargers still draw some power just because they are plugged in. And in these green times it is ofcourse very popular to have warnings everywhere so you can claim to a green company. And every lithium ion and polymer battery contains electronics designed to protect them from abuse. Including over charging. So that will never be a problem on any phone unless you have a defective battery.

Is there a way to disable the message telling you to unplug the charger? I charge my phone overnight and use it as a clock, but when I wake up in the morning and try to see the time there's this huge popup in the middle of the screen telling me my battery has charged.

I think I read that the newest, or maybe just a random middle since something has superseded it, firmware fixed this.

interesting topic thx Beards for sharing your insights.

Overcharging - read the manual
Guys, if you will read the manual that came with your SGS, it says there that "DO NOT OVERCHARGE YOUR BATTERY FOR MORE THAN TWO WEEKS". It obviously means that the battery can be overcharged for more than a day as long as it is not more than 2 weeks ( I doubt if someone will be able to do that). So that confirms also that we can recharge anytime and not necessarily have it done to zero before charging. Hope this helps also

i've pretty much quit worrying about the overcharge after the first month of usage
i was following the auto pop up message, just because i wanted to conserve battery
but having 3 spare battery made me though it's futile
and it was extreme annoying to wakeup in the middle of the night, just to unplug it
it was awesome the day i found that patch on the forum to disable the annoying pop up alert that your battery is full.
now i can sleep the whole night without the alert coming online, and rest at ease knowing if the phone actually alerts me, it'll be a phone call or something important, not some annoying "unplug me plz!" message

Cradle use and battery health

At the office I leave my phone in a cradle. When I get calls I remove the phone to answer and then return it to the cradle when done. My battery goes from 100% down to somewhere in the 90's then charges back to 100% in the cradle. Does this repeated process harm the battery in any way? I've read that these batteries don't suffer from the memory effect, but I'm still not sure if this counts as a charging cycle.

You should always let the battery run down completely some times maybe once a week.

Really? I've read on this forum that there is no need to do that with the new Lithium Ion batteries. I've even read that this could have a negative effect and you should try not to let the battery drain completly.
I don't understand why there isn't a proper battery care section in the manual. Its as if its some kind of voodoo science.

Perhaps not Once a week. But Once a "while"
The reason is that, Phone software uses approximation to calculate the charge left in the Battery. So over time, battery ages and software may not be calibrated to match with the battery's storage capacity. So draining the battery entirely and charging them fully gives the phone's software to assess the battery's health and recalibrate.

It's a lithium battery mate. The only way you can really damage it is by a complete discharge. So long as you don't switch the phone back on once it switches itself off due to low battery you needn't worry about anything else.

Also in theory the lithium batteries have a lifespan of say about a 1000 charges for example and everytime you charge it has one charging less left. This ofcourse isn't exactly how it is in practice but charging the battery alot wears it down. It isn't good either to keep it in the charger for a longer time after it's reached a 100%.

Hi,
this is only partly correct:
Suppose the battery can make 1000 (which I don't believe) charge cycles,
it means that you can charge 1000 times from empty to full.
If you just charge 1000 times from 50% empty to full it counts for 500 cycles!
So,
don't worry, let it stay in the cradle if you like
There are 500 opinions about that but believe, as I wrote is correct.
Theo

Yes, what I said wasn't exact science and I used 1000 cycles as an example, but from what I've read it is better to let the battery drain to less than 50% and then charge it full rather than charge 5% at a time. My previous post was meant to illustrate this.

That's a load of crap, no offense... Lithium batteries have no memory effect and have absolutely no need to be completely discharged, that's a ancient thing from the time of nickel-metal hybrid batteries. The only actual reason for full charge cycles is to calibrate the device for that exact battery.
Keeping a lithium-ion battery in a charger most of the time will wear the battery down faster than getting it drain more and then charging it. Keeping the battery almost fully loaded/in a constant loading state wears the battery capacity by approximately 20% a year (can't recall the source/study just now)(EDIT: and my personal experience is that the battery capacity will wear that much anyway, no matter how you use it). The life-cycle of phones these days are roughly two years nowadays so IMO you can keep it in a cradle with no worries, if you wish. And lets face it, a new battery after a year of usage won't be that big an investment after all.

To add to the above post, running down a lithium battery completely does more damage than benefit. This is almost impossible though with normal use as the phone shuts down long before the battery is completely empty

Battery Calibration process

Is this the definitive way to do it?
http://hemorrdroids.net/battery-calibration/
Those steps came from here, xda devs.
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6 **Root users only** Using a Terminal Emulator, type “su” enter, followed by “rm /data/system/batterystats.bin”
7. Run the device’s battery down until it turns itself off.
8 .Turn the device on and charge for at least 8 hours.
9. Unplug the device, turn off, then charge for another hour.
10. Unplug the device, turn on, wait 2 minutes.
11.Turn off again and charge for another hour.
12. Restart and use as normal.
Quite a performance! Does it preserve battery lifespan, or is it more to do with slowing down battery drain and does it really work?
He mentions 2 interesting things:
"Generally charge them before they get lower than 50%". I didn't know that, so it's actually better to charge more often and not let it drain down?
"USB charging is actually better for the battery and you may get up to 1 hours more standby time." So you gain an hour standby but it takes twice as long to charge the phone.

Nice manual
Will try it

Some will say that its complete nonsense .
Overcharge for 8 hours ??? how does the battery not turn charging off at 100%
Recharge 50% the accepted figure is not to go below 20% to often .
They may be right or wrong their are so many contrasting views on battery charging .

Discharging battery and then reloading it fully, it's the normal procedure for battery calibration for almost all the devices in the world (including computers, etc.).
Step 8 to 11 seems quite a bit strange however.

hm, just seen a different way to calibrate the battery. basically, you drain the battery, take it out for a couple of minutes, put back in, then try to turn it on to make sure it's completely flat.
then you charge it fully, then boot to recovery and wipe battery stats then drain and fully charge. so... which one is more likely to be the better?

that guy also advises to repeat that 12 step, 1-2 day long tedious procedure "every month or so".
it is lunacy honestly speaking

does it work? did he died ?

LOL I dont understand .... I just read in another day that NEVER LET BATTERY GO LOWER THAN 15% and know I read "drain drain drain" Oh welll ...
I also thought that at 100% the charging process stops.

Although this thread is about battery calibration, these questions about battery charging always pop up.
Battery calibration is the process by which you set your device with your battery data.
Every single battery is slightly different. Although there are minimum stantards to every spec of the battery, each battery is different.
Calibrating your battery is nothing more than setting your phone to the real specs of your own battery (since the phone comes configured with the battery factory standards). For example, your phone may be set to use a battery which maximum charge is 1650 mAh, but your battery has a maximum charge of 1625 mAh. That may be within the acceptable factory standard, meaning you have a normal battery, but that also means that your phone will never indicate a 100% charge after you unplug the charger.
If you calibrate that hypothetical battery, you will "tell" your phone that its maximum charge capacity is actually 1625 mAh, meaning from that on your phone's battery indicator will be more accurate.
For that reason, it is necessary to fully discharge and fully recharge your battery for the calibration process, since your device must read the actual specs (minimum charge, maximum charge, charging current, etc) of the installed battery.
I don't know about how many times this full cicle (discharging and recharging) must be performed, but that is the reason why it must be performed for the calibration to succed.
A DIFFERENT THING is the normal discharging and charging process during normal use of the phone.
In this case, you should NEVER let your battery go under 20% and, what few people know, it also should never go over 95%. This stresses the battery and diminish its life time.
Also, and there's a lot of doubts about this, the lower the charging voltage, the slower the charging process, but the longer the battery life.
High charging voltages (like the one used by the charger sold with the phone, which is around 5V) stress the battery, diminishing considerably its life time.
That is true for all lithium-ion batteries!
Therefore it is better to charge your phone through USB (which uses around 4,3V) than to do it using the charger provided with the phone.
You may be asking "If the charging voltage of the charger provided by the manufacturer stresses the battery, why does the manufacturer provide such charger?"
For purely commercial reasons! Higher voltages mean shorter charging cycles, which please the consummer. Moreover, the battery capacity loss with the factory provided charger is around 15-20% a year (considering "normal" to "heavy" use). That is to say that after a year your battery will only reach 80-85% of the maximum charge it used to reach when it was new. And by that time your manufacturer expects you to consider buying a new phone, with more features.
Summing it up:
- calibration is just the process by which you "tell" your phone what the real specs of your battery;
- in normal use, charging your phone through USB is better than doing it with the manufacturer provided charger;
- try not to let your battery charge go under 20% nor above 95%;

Spin three times in clockwise direction with left middle finger on your nose while blinking your eyes with the phone plugged in.
Jump in the air 3 times.
Unplug phone.

Thats some messed up instructions.
Do you have any idea what kind of strain you're putting on the battery while doing all that?
All you're gonna get is some extra minutes, maybe an hour but is it really worth it because you're just reducing overall battery lifespan by doing that procedure over and over.
Specially when you constantly keep the battery at 4200mV (full charge) for a long time. You're practically killing it by overcharging.

Never done a calibration on a battery and most of the time i even didn't let battery to discarge very much and then load it again. Never had a problem with battery life it last how long it should last every time and i've used that battery for years. So the battery "calibration" are kinda useless.

The way I would calibrate my batteries is a bit different. Lithium ion batteries don't need to be drained then charged to full AFAIK, and I even remember reading somewhere that draining it is actually only for NiCad batteries. It used to be relevant when phones were using NiCad but not anymore.
Read: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
As such I have read that the universal way to 'calibrate' batteries is by charging to full, using for a couple of mins and charging again.
What I have been doing is:
1. Charge to full when phone is switched off (doesn't matter if it's from 0% or 99%).
2. Switch on the phone, use for 5 mins.
3. Switch off then charge until full.
4. Repeat step 2 once more
That's it! It seems pretty simple but it seems to have worked for me.

The way i do it is different. Firstly i have the battery calibration app from the market by Nema..then i fully charge my phone and when it says its fully charge i go into the app. There it gives me the instructions on how to calibrate...First i wait till i charge the phone without any interruptions. then click on the app and wait til the battery goes to 4200MV and then i press the calibrate button and then the app does it for me. Then i drain the battery again without any interuptions or breaks during that time and then charge it again once battery dies down and thats it.
there are so many ways being touted on the forums you really dont know which one to go for...but whatever works for each person then who are we to tell someone different just thought i share that

If my battery dies, or gets significally lower capacity after 1 or 2 years of usage, I'll just buy a new one if I plan to keep the phone longer.. Going through these rituals and painstakenly monitor my battery % so that it never goes below 20 % or above 95 % is just not worth it.. Doesn't increase the life THAT much anyway.. I use the phone until I hear the beep for low batt, and from there until I have a charger available.. Most of the time it's before it reaches 10 %, thats good enough for me.. Once in a while it might even go so far that it dies.. Then I charge it till it says 100 %.. Most of the times I plug it when going to bed, and let it charge over night.. This is normal usage and what the battery should be designed to handle, and so far it does..

How to Prolong Lithium-based Batteries

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.)

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?

how should we go about that? play heaps of games? increase brightness? or do you mean drain it slowly like over a day?

You shouldn't, draining batteries fully is no longer recommended practice

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.
