good read as it seems many still maltreat their li-ion
acording to old ni-cam myths
Also, make sure you read http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!
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.

i believe that you have to charge your battery all the way full then use all the power until it dies then you can charge it back again
but not sure

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?

Some articles say that one battery life cycle is used up everytime when a full charge is done. Other articles say that one battery life cycle is used each the battery is connected to the charger.
I have not seen one article that shows the truth with facts.

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.

skimmed a few parts, but thanks for the read mate, learned tons.
as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.
thanks for the info!
Fellow universal users who suffer from battery problems, i know this issue is reccuring and is in many threads and forums now. However i am sorry to increase the talk in another thread. I just thought i would share my peice of advice.
Attached is a pic of the universal battery and below is a little procedure that you might wanna try.
Lets say your universal battery is dying after 10 mins and you just had charged it overnight (meter says it died at 95% or whatever.. ) here is what you do.
1- take the battery out locate the pin provided in this pic attached. its the second pin from the top if you are holding the battery with the connector being to the upper right corner (just see the pic)
2- cover this pin with a thin peice of tape that you will leave temporarily. till the battery fully dies.
3- turn your universal on after placing the battery in it again
4- change the power settings in a way that leaves the universal on for all the time unless you manually turn it off.. so all the power savings are off.
5- let your battery drain all the way until it just turns the universal off.
6- take the battery out and remove the insulation from that pin
7- turn your universal on again and let it charge overnight or till the light turns green.
8- this fixed my universals' battery and now mine turns off at 5%
p.s. while the universal is running and the pin is insulated you will notice that the battery indicator that shows the percentage left doesn't work. (thats the whole point making the ppc blind and not being able to read how much is in the batter and take full advantage of whats in it as far as power goes, this will make the battery realize that it was drained more than usual and forces it to recalculate or recalibrate itself.
by the way you will also notice that the universal wont be able to get charged while that pin is insulated. so again my advice is fully charge your battery , take it out, insulate the pin then drain it all the way , take the insulation out and recharge until light is green.
please post if you had a successful result and hopefully for all who are suffering from this battery problem now they have one more hope.
This is what they call "Resetting" or "Formatting", nad while it's good for NiMH and neccesary for NiCd batteries, it can actually prove harmful to the LiION battery of the Universal, since it may over-deplete the battery.
Use with care, and only if you can't afford a new battery, since this might leave you without a battery!
Deeply discharging of Lithium Batteries
People may remember the videos of burning Dells and Macs. Deeply discharging lithium cells puts them into a critical stage. You may loose a bit more than only the battery ...
well its not deeply discharging
i monitored mine and was playing games on my uni until it turned off once it did then i took the tape out and fully charged it.. then viola it worked fine. i dont see any risk plus yes there is in the lithium batteries a problem similar to the nicad research about it and verify.. anyway you dont have to follow, just saying this worked on 3 of my batteries.
Cheers
NiCd yes, but those are of a completely different architecture. There's something called the Memory effect there, which means that the battery retains the previous charge as the threshold for the next charge, meaning they can't be "topped up", because then only the "top-up" can be drained from the battery.
Lithium Ion batteries retain this memory effect too, that's true. But in them, this is nearly insignificant, meaning the can be topped up at any time, even at 99%, and the almost full charge can be drained. Almost, because there is a minimum threshold beneath which the internal mechanism changes and the battery becomes unusable.
That is why I recommend against deep-discharging the batteries. What I did once was ordered a battery, and noted that it came with a six-month warranty. Now I get a new battery on the warranty(free) every six months, regardless of the state of the old one. But usually by then it startsx to show signs of weakness...
i will try this swith my old bat after my new bat is here. thanks for the fix

Unfortunately, the Memory Effect in Li-Ion batteries can be made worse if the battery is of low quality and/or has impurities in it (due to manufacturing or age). This is why our original, top quality, batteries are dying (due to age) and the cheap ones we buy off ebay are pretty bad (low quality)

I second that. This may be a fix, but be careful!! As with anything in these forums, it caries its own risks.
Probably best just to buy a battery from a respectable shop\dealer and get a warranty with it...
hey guys ... i´ve tried it ...
i think it works, give it a try.
takes 4-6 hours to completely discharge, the i´ve loaded it one night long. today i´ve played long time with my colegues at work, used bluetooth several times, hat some calls... and now, after 10 hours without charging it has 45 % of charge.
at the moment i turned the brightnes to the maximum, with wifi, beam, phone and bluetooth on, to see at wich percent my universal will turn of.
i give you a notice if this happens.
cheers
now ... finaly it turns off at 19 % !
but ... without any warnings or notifications...
but before it always was shutting down at 40 %, now with shutdown value at 19% the battery is more useful as before.
maybe it could help someone.

sounds great try to guve it another shot if you want .. fully charge it and then put the tape on until the universal turns off . maybe you will get closer to zero like i did and if not then.. meh 19% isnt that bad compared to people shutting off at 40 and 80 ...
the only reason i came up with this method was because i read in the wiki that some pople discharged using led or whatever to depelte tha battery or even on bootloader. i thought about it in a way that would make mnore sence using the device itself to deplete its own battery (think about the ammount of power tha led will be drwaing vs the amount the ppc will be drawing ) maybe the chip in the battery claiberates itself on the ammount of draw ... most likely not but it crossed my mind like that so i gave it a shot and it seems to be an exploration by surprise

It sounds very much like "deeply discharging" to me - you are disabling the sensor which is also the failsafe circuit!!! The sensor is not there just to "annoy you" by shutting off early, it's there for safety reasons!
All Lithium ION batteries shut off quite a bit BEFORE they are fully discharged. This is because a truly 100% discharged Li-ION battery (or even close, like 95%) becomes unstable, and this can cause it to set on fire, leak acid, and even violently explode causing you serious injury or burning down your house (people have actually been killed by exploding Li-ION batteries). This is rare yes, but it does happen and it has happened.
We all know that the sensor in some Li-ION batteries can lose its calibration over time, though this is NOT due to a "memory effect", NiCD batteries were the only chemistry which suffered from that problem. But you have no way of knowing if the sensor is really de-calibrated, or it is shutting off because of a fault with the battery, or even that the battery is just nearly dead.
For gods sake people please be careful, this hack may look "cool" and yes it probably will work on quite a few batteries, but it can also be extremely dangerous, and is just not worth the risk, especially when you can get a new battery for less than $20!
Check out these videos to see how violent and extreme a Li-ION explosion can be...

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.

From my experience, the blinky orange LED indicates that the battery is too low to power on the phone. However, for me at least, the battery charges in this state and the light will eventually become steady orange.
I have experienced that some batteries, if allowed to drain too much, will not recharge easily. This may be your case with your anker.
I am guessing you have tried leaving it plugged in for a while?

i see i think that would not be a problem.
one more about the anker battery, is it ok to charge the battery in 5v output charger even in the label of the battery it only says 3.7v?
This happens with the normal battery too if you drain it all the way. Just plug it in, let it charge for a minute or 3 and you can turn it on.
If you get the blinking light for more than 5 minutes of charging than your adapter is not giving it enough juice.
Try to get your hands on an old Motorola charger without a a detachable usb wire and plug that in - imo they tend to give a lot more power, and also dont leave it plugged in for more than a few hours since they make your battery kinda hot.
Also, see if your input might be loose, take a tweezer and gently squeeze from top to bottom to make it better for a tighter fit.
Let me know how it goes, cheers

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.
Who knows what will work try out the method with 2800mAh . may be it works

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.

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.
