I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

conditioning the battery the first time you get a new phone also helps, alot of us just charge for a while them use it. all my phones i let them charge for a full 24 hours right after i get them
My battery only last 6 hours
Ugh, why don't people read the article BEFORE they comment?

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..
Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.
batt problem
how to keep my batt good?
I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

thanks for the info!
I know you want the phone's battery to fully charge and fully drain, but which do I start with? It comes with a partial charge... so should I charge it first? Or drain it first?
Thanks.

Please do not ruin your batteries as far as i know Lithium-Ion batteries don't need to be drained and charged.
Go down to the second bulleted list, the third bullet
I have never ran my battery completely down, and my Kaiser will last for a full day, and i use it a fair amount.
Wow. Thats good to know.
from my understanding it's mandatory for NiCad batteries to be fully drained but Li-Ion are not. :-D i don't want anyone to have a dead battery :-D

Be sure you put it on the charger when you get the low battery notification, or else it may burst into flames!

If you want to prolong the life of your Lithium-Ion battery, DO NOT let it fully drain. This will decrease your battery's overall charge capacity and you'll find yourself having to recharge more frequently. I'm an electrical engineer by education and profession, so here are a few quick points:
1) You do not have to power cycle a Li-Ion battery. Charge it when it drops to about 70% and typically you don't want it to drop below 50%; extremely low voltage levels could render Li-Ion batteries useless because of the internal circuitry.
2) Charge slowly, with a low current, if possible and avoid rapid chargers.
3) Don't leave your battery charging, unnecessarily, when it is already full--this will also diminish it's maximum potential more rapidly. Only charge it when it needs it and unplug it when at 100%.
4) Keep it away from hot environments (e.g. don't leave it sitting in a black car on a hot Summer day, etc.). Heat kills batteries, along with all electronics.
Battery University is a good resource if you're looking for more information on how to take care of your batteries or just want to understand how they work. Hope this helps.

It's actually true that a heavily depleted Li-Ion battery may burst into flames. Li-Ion batteries have a much higher energy density than Ni-Cad and NiMH batteries, and a if they lose too much of their charge, their internal circuitry may become damaged. They should have been more specific in that link, but you should definitely be cautious with Li-Ion battery handling. If it wasn't for the voltage/current regulating circuitry protecting the cells of Li-Ion batteries, they could very well be considered bombs.
So I usually plug my phone in when I come home and unplug it when I leave. Thats bad for my battery? How do I stop it when it reaches 100%?
Man oh man have I been misinformed.
I have ALWAYS heard to drain it fully, then charge it fully...
Fu*kin sh*t!!! I've been destroying li-ion batteries for as long as I've been using them.
So, once you've drained it once it's bad for good, or what?

That's potentially bad for your battery. The protection circuitry in Li-Ion batteries these days are refined enough to prevent overcharging, but leaving it plugged in can still make it build up heat, which I mentioned won't help you. For the average cell phone battery, the typical charge time is about 3 hours for a full cycle. So that being the case, my best advice for you is to check your phone's charge indicator after a few hours and unplug it if it shows it's at 100%.
Lithium-ion battery lifespans are inherently limited by their manufactured date and by the finite number of charge cycles (one charge cycle is considered the charging from 0% to 100%). So if you deplete your battery by 25% each day and recharge to 100% each night, it would take 4 iterations of this process to complete one cycle. Over the course of using your battery you can expect the off-the-shelf maximum potential to decrease by about 20% each year.

Power cycling by fully draining is good practice for NiMH batteries, since they have different properties. But again, for Li-Ion batteries you should avoid doing this. One full depletion may not destroy it necessarily, but there's a good chance that it will have become damaged. This depends on the battery manufacturer's build quality and specifications. You can pretty much be guaranteed a permanently reduced total capacity with a complete discharge though, sorry to say But I guess now you know for future practice to steer clear of the full drain.

Just FYI, most batteries that are included with new cell phones are pre-charged to approximately 70% in order to maintain a charge above the protection circuit breakdown voltage. The end-user shouldn't have any problems just using the battery out of the box, in this state, but it's a good idea to charge the phone before the first use, just to make sure you're starting from a good reference voltage. Lots of manufacturers include charging recommendations with their lithium-ion batteries stating something along the line that the first charge should be 8+ hours. This is excessive and unnecessary. They probably had some inventory of those notes for some older battery technology or carrying on an obsolete heritage practice. All you have to do is let the phone charge till the full-charge indicator lights up.
Power cycling is helpful from time to time to calibrate the sensor (which is different from the reason you want to do this for nicd)
For everyday use, just charge it whenever you can
It's batteries these days are smart enough to not recharge when already full
I'd carry a retractable mini usb cable to charge it frequently (this will help reduce # of cycles used)
Honestly, I think one of the biggest advantage of having a user-replaceable battery is the fact that you could use the phone without worrying too much about all this
I go by the "I'll put my convenience over the battery's" mentality

The initial overcharge and draining is to compensate for the meter's accuracy (or the lack of it) when a battery is first installed
It's entirely possible for the device to report 0% when the battery is actually alive and well
For example, IBM (now Lenovo) has a little software for their laptops that alerts the user when such power cycling is helpful, and so far, I've benefited from it
We should get such software on Windows Mobile!
How much do you think batteries for this phone will cost? And I'm assuming my local AT&T stores will carry them.

Sorry, but as far as I know if the battery meter is 100% the device will prevent overcharging. If you let the device charging overnight in the morning the device will have a normal temperature (it's not getting hot as you said in other post), thus the device doesn't get more that it needs.

I understand, but I think you would agree that the general public probably doesn't understand what "completely discharged" or "heavily depleted" battery really means when we're talking about cell phone batteries becoming flaming bombs.
I just thought there wording was pretty funny.
Strangely I found that after a full charge at night, if I continue to charge via usb either in my car or on my computer for several hours, the battery will last all day with only very little loss...like 10%.
This also works if I hook my phone to the computer when I get home around 6pm and then hook up to wall plug by my bed (I use it for my alarm) it will also work!
Otherwise with just the single night charge (7hrs) it only will last about 12hrs.
I think the Fuze's circuitry shuts off charging before it is fully charged. I'm ordering a seperate battery charger (I have 2 HTC batteries) when the charger comes in I will see if it does a better job than the phone.
Anyone else have similar stories?
Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?

as far as i know, its an known bug
Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.
It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%
96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%
Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?
I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.
You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.
Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there
Turn the tethering on while charging; it'll charge the battery up to 100%
I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App
Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.

It's not a problem...technically. Our phones (and pretty much all modern electronics with Li-ion batteries) don't actually allow for the battery to be "fully" charged to prevent overcharging. Instead, they will trickle charge the last few percent but lie to you and say it's fully charged.
Now, the phone not actually lying to you correctly and saying that it's 100% charged may be an issue, but nevertheless, a full battery is a full battery.

Great, thanks. I understand about the trickle charge, but it should still switch to showing it as "charged". Perhaps this just takes longer to go to "100 percent", but my nexus one never stayed at 99 percent for so long.
A theoretical question... IF the Lithium-ion battery in any modern phone or tablet etc was to completely die, would it still work plugged in?
But more importantly I want to know IF the battery in my phone was being completely dead right now, because of wear and tear and charging it alot, could I still use my phone with a micro USB powerpack/battery bank constantly connected to it?
Thanks

Like the above said, if the battery is not completely dead and has some capacity left, it will work. But it case the battery is completely dead it will not.

If battery is 100% dead then.
Grab a charger and multiply the current written on it with 100.
If the value is somewatn very close ro the battery mAh then that charget could so the trick.
And charger above 1.8A is really hard to get. So to charge bayteries more than 2000mAh can be hard.

your help is appreciated, but you shouldnt comment on such things you know nothing about.
i can get chargers over 1.8a all day no problem.
im not sure what you are trying to explain with all the charger vs battery stuff, but there was no question of an adequate charger.
you seem to be suggesting charging at a higher rate will some how revive a dead battery.
thats just not true. if the battery is dead from reaching the end of its life span as the op suggests in his query, it can not be revived.
further more, you could use a 1,000,000mah charger and it would do or fix nothing.
as long as the charger used can output the amount required by the phone, it doesnt matter how big the charger is beyond that.
there is a charging circuit in all devices that regulate the rate the batteries charge to prevent damage to the battery or device.
chargers dont push out the a or ma listed on them, that value of amperage is the maximum that can be pulled from it.

I understand. Thanks for the answer!
I have an old laptop (like 10 years old), that has a completely dead battery and won't boot if it isn't plugged in, but it does work when it's plugged in, so I thought that maybe it would be the same thing here, but of course not, it makes sense that it's different.
But even with a new, modern phone, I guess it would be hard to completely kill the battery, even when charging it alot?
I mean, even if I would charge it 2 times everyday for 5 years, maybe it would still have some percent left of it's battery capacity, maybe 10% or something, and then it would work.

I have an old laptop (like 10 years old), that has a completely dead battery and won't boot if it isn't plugged in, but it does work when it's plugged in, so I thought that maybe it would be the same thing here, but of course not, it makes sense that it's different.
But even with a new, modern phone, I guess it would be hard to completely kill the battery, even when charging it alot?
I mean, even if I would charge it 2 times everyday for 5 years, maybe it would still have some percent left of it's battery capacity, maybe 10% or something, and then it would work.

its fairly rare to see a battery go completely dead from just being worn out. usually users will replace it when it gets to some point of limited usefulness.
sure some times they die from defect, and some times they die from users running down until 0 and the phone shuts off.
the latter trips a safety in the battery and makes it all but useless. this can be fixed, but thats another discussion.
i dont know how laptop batteries work with respect to charge.
phones though, i have seen from experience. when the battery is completely dead the phone will not start even plugged in, until it takes a small amount of charge, to be able to sustain the device on the battery while charging.
as long as your battery can sustain this minimal amount of charge, it should work while plugged in.
there really is no way to tell if, or how long, it will be able to maintain this low charge state. any stress on the battery from heavy use is likely to cause it to shut off until it reaches the minimum threshold again.
also when the battery is this weak, its possible for some sort of internal fault, resulting in the loss of ability to accept even the smallest of charge.
if your battery gets to this weak state, its best to just get a new one. even if its a cheap knock off that doesnt work as good as the old one used to. at least you will have something to work with, and not be worried from day to day if it will work or not.
i hope this clears things up for you

Oh, that's good to know.
And I'm not so worried about that, I never let my phone drop below 10% and most often I charge it when it hits 20% and charge it up to 90%. I believe that's the best for the battery.
I am kinda regretting now that I bought a Xperia Z5C though, I don't like that the battery isn't changeable. But it's a great phone other than that, so I think it will be okay. And the battery is quite high capacity so I hope that it will work fine for at least 3 years, even if I charge it daily.
ETA: Interestingly, I had a Xperia Z1 before this phone, and I had the Z1 for a litte more than 2 years, and charged it almost everyday, and the battery on it was fine, or more than that, it was Good, I was getting 4-5 hours screen time on a charge just a month ago.. So??? I shouldn't be worrying about this anymore and instead enjoy my new phone

many users run the phone to 0 often without issue, but its really a horrible thing to do. there are many documented cases of it not turning on any more, however likely small compared to the amount of times its done. i was just making the facts known that the safety is there, and there is a risk of tripping it.
the problem would be compounded on a sealed phone, as the only fix requires you to take the battery out.
your charging cycle is very good for getting the max life from your battery :good: not too low and not too high.
many will argue this, and claim the benefit is very small, but according to the experts at battery university, not too low and not too high is the best way to get max life from these types of batteries. it keeps the stress levels while charging out of the highest ranges.

Laptop chargers are a bit different from the android chargers.
Laptop chargers are designed to handel heavy charges which charges the battery at at its rated voltage. Like a 12volt laptop charger will charge a 12volt battery. Thats why with battery dead charger can handel all the work.
Android is a bit different.
Its chargers are rated of higher voltagea than battery.
Thats a good thing because at higher voltages we requir less ampere of current per hour to charge it.
I mean to say in previous post that if you grab a charger for your device just pullout the battery and use any other device battery for first boot. And when it start booting then you can just remove that battery and device will run on chrger.

all batteries charge at a higher rate than they are rated at, phone, laptop, car, doesnt matter.
if they didnt, they would take a very long time to reach full charge, and could only do so if not being used.
i would like to see some proof that a phone will stay on booted, with no battery. post some links for me to review please.
I have done it i will send you a video ok
What about cpuZ?!

"what about" you read the forum rules, particularly the part that says not to spam threads with off topic posts.
