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!
Hello everyone
I was wondering if its ok to leave the transformer connected to the charger.
Is it like the Evo with trickle down when it reaches 100%
I dont want to over charge it. If it were my laptop i would disconnect the battery at full charge. But its not possible to do that with the transformer.
I want to keep my cycle count low and prevent over charing.
I also wonder what happens in a few years when the battery is shot...
Charging is what damages Li-Ion batteries... I'd recommend not keeping it on the charger all the time. Android will purposely not keep the battery at 100% to help avoid some damage.
Li-ion prefer to be around 20-80% charge.
When battery is 100% and you keep the charger connected, heat will begin to build up and eventually you will kill your battery.
I'd do as with a notebook: charge till 100%, then remove battery or charger (in case of the tablet charger ) . Then use your tablet and recharge when needed / desired. And from time to time a full charge / discharge cycle won't do any harm.
Just my 2 cents.
Regards.
These tablets don't automatically recognize when it's fully charged and turn off the charging?

They do. There are other threads asking why thier TF's don't show 100% when unplgged from the charger. Same as it does on my Evo.
I think pretty much every modern device recognizes a full charge and responds accordingly. In fact, MacBooks will throttle performance if the battery ISN'T kept in while the system is running on A/C.
Heat will damage a battery, but it's not heat from charging but heat from operation. If a notebook is poorly designed and the battery is near a heat source, then removing the battery might be a good idea (except with the aforementioned MacBooks), but that's independent of the charging issue.
I think it's fine to keep it plugged in. These devices are smart enough to manage such things. Of course, the TF's charging cable's so short it's hard to use when plugged in, but that's a different issue entirely.

From what I understand this process cannot and will not kill the battery. This did happen in the old type of batteries with the ,emory effect but these new batteries and the OS's management system for charging does not allow the battery to be killed.
it will heat up and that would happen as there is a flow of electricity but not to a level that would kill the battery.

IS it normal to go from 4% battery to 99% in under 3 hours ?

Still dont know about it. Because I think its like my EVO and technology got so good that my battery is protected.
I really dont want my transformer to become a expensive paper weight or non-mobile because after a few years it has 45 mins battery life.
I've got the first full charge and full depletion done. Is it ok to use while charging now as long as I fully charge and fully deplete it a couple more times?

I am no expert, but I have spent some time searching around the internet looking for information on the best methods for improving the life of a battery. Most of the information I have found said it is bad to completely discharge a Li-polymer battery. The articarles stated it was best to charge the battery when it reaches 20% to avoid shortening its life.

Batteries are like muscles - they like to be exercised.
Leaving the unit plugged in WILL NOT HURT YOUR BATTERY. Period. The charging circuitry in modern devices is smart enough to cut current to the battery once it has reached a certain level of resistance.
Batteries do not like being deeply discharged. Most devices will shut off before the battery gets too deeply discharged, but it's never a good idea to tempt fate by running it until the device shuts off.
What really determines a battery's life is the number of cycles it has been put through. A cycle would be a full charge followed by a full (or to a lower end threshold) discharge.
The old original Lithium Ion batteries used in laptops would usually last about 300 full cycles or so - about a year if you used it on the battery every day. Partial discharges of course only count as fractions of a cycle.
Given the life of these types of devices, considering we'll likely upgrade to the next big thing in a year or so, I don't think anyone here will come close to 'wearing out' a battery.

As stated, these are Li-Ion batteries, and they do not need to be trained. The only reason you might need to do any training is to calibrate Android's understanding of the battery (although I doubt you need to do a full discharge for that, either).
It's not going to suddenly kill it, but it will over time hurt your battery's life.
I went ahead and did a full discharge/charge cycle, but only because Asus said to do so in the manual. Maybe the copywriter just copied/pasted from a circa 1990's manual for a device with a NiCd battery, but I figured if they're suggesting it, I might as well do it.
Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

just charge it when it needs it, dont worry about what % its at, and dont worry about running them right down... the phone will power down before it gets to a dangerous level for the battery.
dont leave it plugged in all the time when its sat at 100, dont leave it down at 0 and just forget about it for weeks on end...
thats all you need to know

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).
I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month
If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.
u have to calibrate the battery too
Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.
I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.
Charge battery between 20% - 80%
Do not use phone while charging
Unplug charger when battery full
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 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.
Hello guys sorry if it is an innapropriate question but I want to know if it is okay to charge my s8+ over night.. does it damages the phone battery or not ? Thanks
I wouldnt. Doubt it would but would but i find it pointless. It charges pretty quick and wouldnt want to leave it charging for 5+hrs The battery is superb i would quick charge a few mins before bed. Ive gone to bed with 19% and had 17% when i woke the next morning.

Yeah I know but i work in the morning at 7 thats why . I use it at night leave it at about 10%
Been doing that with my phones for years, haven't had a problem yet.
technically with Lith Ion the less you let it die all the way the better it is for the battery.

It's not going to outright destroy the battery, but definitely better not to keep it on the charger. I cannot speak to your schedule and work environment. I charge mine mid day at work. If your usage is generally the same on a daily basis, just find a spot where you can squeeze in a charge or two during the day.
Always changed overnight for ever I can Remeber. Never faced any issues.

i leave the phone on the wireless charger. it better for the battery or is the same?
let me clear it..
1st of all in modern battry charging technology overnight charging doesnt harm battery at all as lith ion batt never get overcharged..bcoz once its 100%(max threshold) charging stop and phone use batt powr
after that once it get around 100% ( lower threshold) it start charging again...
STILL I PERSONAL ADVICE TO CHARGE OVERNIGHT WITH FASTCHARGING MODE OFF(((OFFF)).

As far as I know, technically wireless chargers are worse for the battery than a wired. They produce more heat, which technically will have a larger impact on the battery. That being said, I doubt there is any appreciable difference.

Good point. Does ths fan cooler on the wireless one prevent as much heat?
The battery retains 95% battery life after a year of normal charging, I wouldn't worry about depreciation. Relax and enjoy the phone
No, you can charge your android overnight as they are smart enough
Boooom! Lol.....just kidding I hope
Stick with the samsung fast charger. I have a lot of other ones, and only the samsung stay cool (fan) and doesn't cycle like the cheap ones do.
Yes, as most have said, you can charge overnight. I have done this every single night for years, on all my flagship devices. Smartphone batteries have technology in them to stop charging when they hit 200% and only trickle charge them. It won't do any damage or won't cause long term battery life issues.
Just turn off fast charge if you're going to charge overnight.

I have the new Samsung wireless fast charger and I'd say it's just a tad warm kinda like the USB-C charging

I've also heard the opposite, as wireless chargers charge slower they put less pressure on the battery which helps it not degrade as fast. How much difference it would make either way I dont know, possibly hardly any.
I do know keeping it between 40-80 is widely regarded as being a lot better for li-ion battery degradation than going to 100% all the time or running it really low. Accubattery for example will say you used about 0.2 battery cycles going from 35% to 80%, but 0.92 battery cycles going from 55% to maximum. They are probably just using that 40-80 rule to work it out, but assuming it is correct, you can see how much effect it has, being nearly 5x more battery cycles despite both being around a 50% charge up.
So charging it overnight will get it to maximum, which isn't great in terms of battery cycles. I have seen a couple of battery apps that I think can manage charging so that it notifies you at 80% to unplug it, but I don't think they can actually stop the charge at 80% if you leave it plugged in (althought I might be wrong on that). Again how much real difference it will make I don't really know, and it probably depends how long you plan on keeping the phone, 1 year then it shouldn't be too much of an issue, 2 years or more and I would probably at least try to keep it between 40-80% when possible.
Ha,
Been charging all my phones overnight.
Been using wireless charging since the note 3 and always please it on the charger when im next to it and not using my phone.
Never had a battery problem
Thanks everyone for their answers ..*let the overnight charging begin*
I used Ampere to check how much current was going to my phone when it was fully charged and it read 0.0 so I believe the phone cuts off the charging function when fully charged. As even on 100% without the "fully charged" portion on, it will still show trickling voltage.
Hope this helps. I also advise turning fast charging off at night just to be safe.
