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.
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.

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
I have the seidio 3500 mah and love, especially after I found out how to manage it properly. Couple tricks with these larger batteries are as follows. This should work with all larger batteries.
1. When the charging light turns green, the battery is only at 1500. Keep on charge for about 3 hours longer or more to get full charges.
2. Wipe battery stats. Recovery, advanced, wipe battery stats. When you hit go, screen will go black for about 30 seconds. It's o.k. it's doing the wipe.
3.Condition the battery. Charge all the way, let run down completely till phone dies. Then charge all the way again. Do this bout 3 times. Should condition about 0nce a month to prolong battery life.
Follow these steps and you will love your big battery. I love mine. My Seidio runs bout a day and a half and I am constantly doing stuff with the phone. ENJOY!!!!
Ok are you using juice defender for it or any application that save battery life

Nope, I only use task killers that can auto kill when screen turns off. Also, Itry to leave GPS turned off unless I need to turn it on. I just do as I posted origanally and it works great. I do keep my origal batt and back door available so when the batt gets low I can just run it completely dead. Oh yeah, I also have a spare batt charger the just charges the batt by itself.

Some apps hang so it helps to use a task killer, I exclude the apps that usually start in their own. I also noticed after I close everything after a reboot, the phone runs much smoother with just the necessary apps running.

That makes no sense. When the light is green, the battery is at 4.15-4.2 V, and it's no longer charged at this point.
Task killer should only be used if an app hangs, not set to automatic kill, android does this on it's own. GPS only turns on when an app needs it so turning it off does nothing. I get a full day and a half on a standard battery with Wifi on, GPS on and juice defender set to every 15 minutes which I'm now turning off due to facebook app and push notifications.

The voltage isn't the the same as amps. When the batt is at 1500 it still has the proper voltage to run the phone but the cells are not full. The EVO is set to turn the light green when the batt is at 1500. I found this to be true cause when I first got the batt I would charge till it turned green then off I went. I wasn't getting any better batt life until I found info on how to properly charge these batts. Now I get bout a day and a half.
Squick is right. Let it charge for another few hours after it goes green for the extended battery from Seidio. If you unplug it right after it hits 100, it'll drop to 75 pretty quick. So let it keep charging.

The charging circuit has no way of the determining the charge capacity. The only property that can be measured is the voltage, and consequently the rate at which voltage is changing and the current during charging.
If the charging circuit relied on capacity, you'd never be able to charge past 1500mah.
The basic process is to charge at constant current until each cell reaches 4.2 V; the charger must then gradually reduce the charge current while holding the cell voltage at 4.2 V until the charge current has dropped to a small percentage of the initial charge rate, at which point the battery is considered 100% charged. Some manufacturers specify 2%, others 3%, but other values are also possible.

After all that I have read and personally tested, the battery is not fully charged when the light turns green. I have taken the phone off charge once the light turned green and the battery lasted no longer than a 1500. I found numerous threads that stated that the evo goes green once the battery reaches the 1500 point and that you need to charge well past the green full light. Once I started letting it charge at least 3 hours over, I get awesome battery life. If there is another explaination for this I would love to know!

Try this:
1) Charge the phone till the light goes green.
2) Power off the phone completely (shut down).
3) Charge more with the phone being off until the light goes green again.
I'm guessing the extended battery like 3500mAh should be nearly fully charged at this point, and it shouldn't take more than 30-45 minutes for the second charge, as opposed to 3 hours.
The reason for this behavior, and I'm guesstimating here, is that HTC optimizes charging in the kernel to never exceed a certain limit, which is very close to 90-95% charge. A double capacity battery, having a different charging rate and the limit current, should be at 80-90% - double the difference - when charged with the phone on. Eliminating this optimization from HTC by charging with the phone off should, in principle, allow faster charging to nearly 100%.

Nonsense! The Evo uses a LiPo battery and there is no beneficial reason whatsoever to running the battery down. In fact, running the battery down unnecessarily will reduce the cycle life and the calendar life. In the simplest of terms, the LiPo cell chemistry is only capable of so many charge-discharge cycles before it loses significant ability to store energy and unnecessary cycles just use 'em up unnecessarily.
In fact, a bunch of partial charge-discharge cycles are a lot easier on LiPo cells than a few full charge-discharge cycles. In other words, your battery will remain healthy a lot longer if you charge it whenever you can instead of waiting until you have to all the time.

Agreed. The only reason to discharge the battery completely might be to reset the battery calibration data and to recalibrate. But I really don't know if that even works.
Just saw the posts. I did not know that, but the rest still seems to work. If I charge the vary well past the green light, I get almost 2 days of use out of it.

I need testers for my battery fix that in theory, should charge all batteries (stock and extended) to maximum capacity. So far I tested it with a stock battery and it only lost 4% in an hour after being on the charger for 2 hours. Im testing my extended battery right now(it's only 1800mah).
here's the thread: http://forum.xda-developers.com/showthread.php?t=876590
Don't be stupid and fall for this trick. It's only prank in case noobs don't know. A day and a half is normal for 3500MAH battery with full use ( abuse the hell out of it ).
I think nabbed has got it, your battery loops once it gets to the max the battery can hold. Its megahertz, not amps or volts.. Your phone tries maintaining 100% by letting itself lose power and have to charge back up. Like I said, its a loop pattern.
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?

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.

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.

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.
Dear readers,
I am going to buy a new battery for my HD2 but there is a problem.
I would need to train the new battery and charge it full the first time without turning on the HD2 right?
How can i do this when my HD2 keeps turning on by itself? I even think my phone charges when it is off?
My phone runs ics 4 with magldr.
Can anyone help me out?
Just drain the battery normally and charge it when you sleep?
Draining a new battery will make it unusable???
No it will be fine, Li-ion are quite durable & do not have charge state preferences.
Just buy a new battery & put it in your HD2 & use it normally, if charge very low when first turn it on > plug it in & charge to full.
Then why do people and retailers keep advising me to fully charge batteries before first use?
Cause batteries don't come fully charged?!
But if you charge it first how do you know the battery is fully charged without draining it first since battery stats are incorrect?
Hmmm, i have been told that fully charging it at the first time before first use gives u better battery performance and better battery stats. U are telling me the opposite thing lol? You could see it is full by the constant green led? But if it is like you are telling me then that indication would be false?? Do i get it right?
A new batteries capacity should increase after first few cycles as will devices calibration of the new cell.
The Battery itself is dumb & you can use what method you like really with li-ion cells to charge them.
Only issue sometimes seen is devices recognition of cell power level is not shown correctly.
Have recently issued 20 new cells for our HD2 fleet, staff use them as they needed & without stringent charge routines & all is fine.
A little common sense is all that is needed & maybe calibration reset if a problem appears.

What if you get a fake/defective battery that only holds 40% capacity and reports that as 80% and you charge the battery to report 100% (which activates the green led). How would you find out that this battery is holding a real 100% charge without draining it first?
With an app that shows u the amount of mAh?
Or is that impossible?
Any app calculating mAh will need a few cycles of the battery to give an accurate estimate. Reading any data direct from a cell is pointless as the cheap cells use chips to display false capacities.
In your circumstances just install new battery & charge while device is on then charge as required & only worry if run time seems very bad.

Now thats major bull. No app can give 100% correct info about battery capacity.
The only one method of correctly defining battery capacity is by using computerized battery analyzer.
If you want to get most of your new battery(Li-ion/poly):
-first make several charge/discharge cycles(after 5-10 you will get desired OEM capacity)
-charge it with wall charger, do not charge through USB
-charge it whenever you can, even if few % are only used
-avoid complete battery discharge(Lithium cells hate complete discharge!)
-keep it at reasonable temperatures, dry
-and don't buy cheap/promising alternatives. Only OEMs are worth buying. Forget about Mugen Magic(proof: www.batteryboss.org)
Battery apps are not always acurrate. They only measure in certain intervals (and then estimate the other stats), which only tells you the current in that instantance of time and the rest is ignored. Also if you undervolt, sometimes the drain measured higher than usual and the battery percentage becomes erractic (ie increasing after a reboot) that will easily change the estimated capacity.
