How long will a charged "spare" battery hold its charge?

If i pick up a spare battery to use as a emergency backup for my captivate how long can I leave it say.... sitting in my car.

One or two months, maybe longer depending on how low you want it's charge to go before using it.
Of course as soon as it's made it starts loosing total capacity.
A charger left in your car will do more good (sorry, couldn't resist)
Not sure if those "emergency" battery pack chargers are any good, might be worth looking into.

A day if you don't use your phone lol

An in car charger is definately the way to go if thats what you're wanting to do. But the li-ion chemistry can hold its charge for several months, but it doesnt do them any good leaving them charged for any length of time. They lose their total capacity much faster if theyre left charged, and this is worsened if left in a hot environment (like in a car during the summer).
It would be best to cycle the two batteries (use them alternately) so they dont stay charged for too long.
Hope this helps

Any gadgets left in a "hot evironment" for a long time will not be a smart thing to do. It's always best to charge it fully and unplug it from the charger/outlet.

Hi
if the battery has no defects and is fully charged then it should run just as long as your normal battery.

A spare battery should be used regularly too, do not live it for a month without using it because sometimes some battery don't work after a long time of storage. But I have tried not using my spare charged battery for about a month and still it works after i put it on my phone, it has a full battery. As long as they are not exposed to heat/sun it can last long.

I lost a genuine HTC battery and found it moving house about 6 or 8 months later
I was pretty surprised to see it still had about 3/4 charge in it and worked fine.

I would like to add, that if you do not want your li-ion battery to loose their total capacity it's best NOT to keep it at all in car (where temperature is above 18C) and if left for longer time - DO not keep it FULLY charged.
The best for 'spare' li-ion battery is to be charged with ~40% for extending its live.
Also do NOT discharge your battery completely or leave it discharged.
On the other side it 'likes' to be charged constantly and even sometimes slightly overcharged (it does not have 'memory' - so charging at any moment will not affect it's life).

Maybe an extended battery

Cheap eBay extended battery question..

So I just got this battery hm around Wednesday or Thursday, and I have let it die down to around 10% or less and recharged it overnight several times and I still only see a slight difference in battery life. I am (I would say) a moderate user and I know some people say they get around 2 days on heavy use so I wonder what I'm doing wrong..? I ran the SU command to delete the battery.bin file to wipe the stats while it was fully charged, then let it run the whole day again only getting around 12 hrs (probably would have been shorter, but I have juicedefender running, and I was at work for 5 1/2 hrs of those 12) and then I stuck it on the charger at about 7:45 and then around 12 it was fully charged and I of course turned it off, then back on and it said it was around 80% so I let it charged to full, reset it again then when I turned it back on it said it was full. I took it off the charger and within minutes it dropped 1% every minute or 2 and now around 15 minutes later it's at 86% and I'm not even doing anything, just sitting here with the screen on and Skype is running. I've only drained it/fully charged it a few times maybe 3 or 4 should I just keep doing that or did I just get a crappy battery? It's better life than the stock, so I can't help but think that it's not crappy just not fully calibrated or "worn in" yet. Any help would be greatly appreciated!

I too have a cheapo extended battery from eBay, for the first week I hated it, but finally I actually just let the thing completely die to wear the phone shut down and wouldn't turn back on, then I recharged the battery completely in a standalone charger(also ebay), then put it back in the phone and used normally, charging and discharging and now I can't even dream of going back to the OEM battery, my battery life has much more than doubled. I use my phone like most here with CM7 up to date on nightlys and I'm happy as can be. I also like the ext back on the cheapos much better than the seidio flavor.

So you use the wall charger from eBay to charge it? I don't want to take my battery out to charge it though every night, let alone turn it off because I use it as an alarm clock :X. I've read a whole bunch of different ways of how to charge it in your phone and most people even one of the legitimate companies (Seido) who sells it, says that if you let it go an hr or 2 after the light turns green its good to go, but I don't believe it charges after the light turns green hence why the charging icon on the battery goes away. people may "think" it does but I honestly don't think it does and if anybody can prove otherwise I might have to buy the external charger :/

Yes get an external charger, Preferably 2 batteries and 1 external charger.

I just ordered a wall charger for like $15 I hope this works. I'll just charge my extended battery at night and use my other battery when the extended is charging

I used the external charger just once to "calibrate" the battery it seemed? Since then I've not taken the battery from the phone and just charged it with the phone charger(plugging it in) and I have noticed a huge change in run time.

How do you charge it though now that its calibrated? Do you just leave it on the charger for a few hrs after it hits green or do you have to turn the phone off and back on then stick it on the charger

Well my cheap battery has not blown up with sbc kernels

Yeah, its been about a week and my battery still can't even hold a charge, even if it isn't fully charging. It dies quicker than my stock battery. I told the guy I bought it from, and he said he'd send me a new one so I'm back to the stock battery for now until I get this one next week :/

Hey guys, i know it's a tiny bit off topic, but what about a battery pack??

i have two of those things and they work perfectly. plus, i don't have to kill the phone, open her up and swap batteries. additionally, it'll charge two devices at a time. bonus!

Hmm see that's what I'm trying to get rid of lol having to plug it in all the time. Plus I actually like the bigger back, I personally don't like the thin size of the evo I feel like I could drop it at any time.

How are you guys getting so many hours? I only get like 8 Hours on my heavy use and i bought a 3500mah extended battery wtf? I'm also using the net Netarchy sbc 3.2 more havs and mym rom with setcpu running profiles. What am I doing wrong? I even have juice defender running aswell.

I had my 3500 extended battery and at first it wasnt too good. But after switching to an external charger for all charges and completely letting the battery die out im getting a whole days worth of heavy use with no worries.
No rooting or any battery controls.

Battery life: frequent micro charges vs more spaced charges

What is best in terms of battery longevity?
1 - Wait until battery level fall below a certain level (and which % is ideal to start charging)
or
2- Charge the battery as frequently soon as possible
Thanks for any advice

Lithium batteries last longer if you do not disharge them all the way..
I don't have reference material handy. If you really want some, I will try and find some again..
But basically charge the battery whenever you can or at least do not let it go below say 20 or 25 percent if you are concerned about that. Since our devices have a replaceable battery I do not stress out over it too much. If I cut 6 months off the battery and it only lasts me a year or so, I can always just put in a new one, they are not that expensive..
Now on a device without a replaceable battery is where you really have to be concerned..

Drain till 20% then recharge it. Best way to use lithium battery.

yea could be, just don't discharge or overcharge the battery :good:

i haven't looked into it lately. but i'm pretty sure our phones don't discharge the battery till it's technically at 0% (~3V)
i'll run my phone down tonight and check it with a mutlimeter to verify...
i wouldn't be surprised to find out the phone stops charging the battery before it's at a true 100% either. so i guess i'll check that too.

I was also puzzled by the warning of overcharging issue. I read somewhere that the GalNexus has an electronic which prevents overcharging. I am very interested by your verification if that is true. Because frankly, it would be very inconvenient to wake in the middle of every night to disconnect the charger.

there are wall chargers that have timers on them, they shut off power after a custom time

You can't overcharge a phone by leaving it plugged in all night, the charging circuit only allows it to charge to a certain point. You can overcharge a phone by plugging it in everytime it hits 90% because you're being all OCD about it. Over time that will screw up your battery

The main thing you want to avoid is heat, which will seriously degrade the life of the battery. I only charge my phone once a day(before I go to bed). I've been doing this since I got my first Android device(well, my Nexus S had to be charged like 3 times a day :| ) and have never run into any premature battery failures.

Quite the opposite is true, regarding the second part of your reply, actually.

Actually, it's never a bad time to charge a lithium battery because the charge you are using is always the oldest added. Consider it as a bucket with golf balls and a hole at the bottom. You load golf balls from the top and use them one at a time from the hole on the bottom.
All lithium batteries have circuitry built into them to prevent overcharging but at the same time the circuitry needs power to operate. If you drain your battery down to nothing and leave it uncharged for a long time the circuitry will drain the reserve and you will not be able to charge it at all.
Another fact about lithium batteries is that you can charge them more times than their natural life span. So as soon as a battery is manufactured it starts to go bad just sitting on a shelf. So buy them fresh. They have thousands of charge cycles and only about 2-3 years life. So even if you charge all cells inside 2-3 times daily (remember the bucket analogy) that's only about 1,000 charges in a year.
Also, you could plug your phone in and out 100 times during one day and still not complete one full charge cycle.
Conclusion ; charge it whenever you can, whenever you want. You'll need a new battery in about 2-3 years anyway in which time you'll most likely get a new phone.

Thanks obsanity. Oh wow, this is indeed even better. Thank you very much for the technical background explanation.

the cheap ebay batteries use a cheap/inferior chemistry. they may be capable of the same Mah as stock for example when new, but i wouldn't count on it to age as well compared to OEM.

I would say they are not only old but also fake claims of capacity. It's actually hard to measure how much a battery can hold so they take advantage of it. Who's going to prove them wrong?

system shutdown occurs on the Galaxy Nexus at 3.39 volts (assumed, measured voltage with no load is 3.42)
in theory you could get a bit better battery life at the cost of cell longevity by running it down to 3.2 volts. assuming the system could continue to function.
EDIT: full system charge is 4.2 volts, as expected. i don't see a practical benefit to modifying the system to run at below 3.4 volts, even if possible.

[Q] Confusion regarding the battery cycles

I recently bought a note 3 and I wanted to ask is it okay if I put it into overnight charge even if the battery is 60-70% ?
Does putting it on a charger over long period of times affect the battery life?

battery has protective circuit that will cut off the current when fully charged, since Li-ion batts are very sensitive to overcharging and discharging bellow spec and will get damaged quickly if done so. However, since there is always some possibility of malfunction I would not leave the batt. at home on the charger and left for 2 weeks vacation, but overnight should be fine, probably many people do so.

Thank you Pete for such an elaborate reply. In your opinion would it affect the battery if I put the phone over night every night for, let's say, 3-4 months?

I charge nightly so that when I wake up the phone is fully charged. Seriously, if the battery starts to wear out you can simply replace it. It is removable. Not a big deal.

I leave it charging every night

Buy an extra battery and swap out when it gets down to 15%. Saves wear and tear on the charging port and keeps away extraneous heat from having the phone itself charging the battery.

Imho even if you would charge overnight you wont notice any difference untill your phone is EOL. Even if you would treat your liion battery like a princess it would still die in ~5 years (please correct me if im wrong).
Even though this is only my personal experience and your mileage may differ, but im currently using a HTC HD2 which is still going strong on its first battery. I plug it in almost every night before i go to bed.
Edit: and I must add that really your phone is designed to be used like this. If you only have 70% left and you really need that extra juice the next (few) day(s) because you wont have a charger with you, just plug it in as you go to bed.
If you really go out of your way to rape your battery every day, just buy a new one when its EOL, if you haven't gotten a new device already.

Battery Life/Damage

Hey guys I'm often a lurker on here and don't post a whole lot but came across this article and found it interesting. Thought I'd share... Also, I like to leave my HTC ONE plugged in on my desk stand at work with the "Daydream" clock function running (basically using my phone as a desk clock). Do you think leaving it plugged in charging all day running this clock is doing any damage to my battery? It of course fills up and charges to 100% pretty quickly because I never really let it get below 80%. Below is my charging habit...
1. Charges all night at my bedside
2. Take it off the charger in the morning while getting ready for work and my drive
3. Get to work, plug it in for 6-7 hours running Daydream
4. Take it off the charger and go home... (off the charger for about 4-5 hours in the evening)
5. Go to bed, plug it in, and start all over again...
Oh and here's the article :lol:

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

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

never let it die

I have always left my phone's plugged in constantly and never an issue. Once my phone hits 100% it stops charging and then is very cool to the touch from then on.I heard phone's now has a failsafe that will stop charging and start running the phone off the charger and not battery.

What's the best battery conservative rom?

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

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

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

I didn't say regularly. I said every 30-40 days. I have a lot of experience with lithium cells - both manufacturing and selling.
Before getting the One, I regularly used my HiTec lithium charger on my thunderbolt battery to run a discharge cycle, and then balance/charge it slowly.
No one need be afraid of their phone getting below 10%. It isn't causing any damage.

Well i guess its all a matter of opinion. Me and my wifes first smart phones were the htc incredible. I would never let mine die and the battery lasted fir 3 1/2 years. My wife would let hers die once or twice a month, and it lasted for 14 months before it needed a new battery. Got on her about not letting it die after we replaced the battery, much to my surprise she listened, and the replacement lasted for another 2 1/2 years. Both of our batteries actually still work today just not used to much anymore.

I had the dinc2 and followed the same procedure he used and pretty much nuked a battery from doing that same procedure. In less than a year my battery was bad. To each their own but I still don't suggest running it all the way out.

even anker, who is is probably the biggest portable battery manufacturer recommends not letting their products get below 25% because it can reduce the lifespan of the pack. They state that keeping it between 25-75% is ideal.

Interesting article, thanks for sharing OP.
I also leave my phone plugged in while sitting at my desk and let it charge up. Typically I plug into my laptop via usb while at work, once fully charged it shows 'fully charged' and switches the led status light to green.
I try to never let it die either but have to travel for work and do get very low on occasion, once I get down to 10% I typically just shut to phone off to preserve power while I am flying and avoid turning it back on again til I can get it on a charger.

Battery Life
I'm new to this phone,so I'm not entirely sure how the battery life is ... but I heard a while ago that you get the best battery life out of phones when you only plug them in to charge when they are completely dead. I don't do it often enough to see a difference, but has anybody else done it?

You probably get a much more consistent charge while it is dead/powered off. The only problem there is does letting your phone die occasionally ruin your battery or not?

Did you not read the first message in this thread. wherein it says:
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible.
and
Never go to zero.

Alright, alright - I was merely saying I'd heard a theory stating otherwise.

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