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.

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?

batteries will degrade over time....would you be keeping this tablet for over 2-3 years? a simple battery change could work if ever needed
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.
So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.
Actually what happens when you leave the phone connected to the charger is that it stops charging completely. I do not think it affects battery life in any noticeable way, unless you leave it for hours connected maybe.
If you're using your phone quite heavily surely you will be constantly charging if the optimal usage is between 50 and 90% of charge?

What will happen is that when it drops to 99%, it will charge back to 100%. Over the night, it could happen many times. It is a circulating advice for a long time now: don't let your phone on the charger for the night.
I must admit I try never to charge it overnight. I'm managing to get just over a day of use before it needs charging.
but the proof is missing, there are many such fairies in the internet, even if, after 2 years, most buy a new phone anyway. and so long holds each battery! With my s6 I still get over the day. and charge it always over night!

I agree 100% with the above quote. There is no real proof one way or another. It is all speculation run amok.
The only fact is that the battery will slowly degrade over time. THis is what the OEM's want!
They make it very difficult to replace the battery so that you will buy a new phone... plain and simple!
Any phone built within the last two years is more than powerful enough to do anything needed for communications... the reason cell phones exist in the first place. I always charge my phones (when needed) overnight. They all last as long as any other phone.
I too am caught in this ridiculous merry-go-round of buying a new phone all the time because we want to sell them before the battery gets too old.
Progress...argh.
There's a reason why electric vehicles don't use 100% of their battery capacity
But worrying about your phone's battery life is too much of a hassle, I'll have a new phone by the time this one is useless
And since the battery is not user replaceable, it has the same warranty time as the phone. If there are problems, samsung can replace my battery

Charging your phone to 100% won't harm it. Letting it die at 0% though can harm it. Lithium-ion batteries don't like dying, but charging them to 100% won't hurt it, in fact leaving it plugged in for hours, even days afterward, also won't harm it. Chargers stop charging devices at 100%. Phones will be fine as long as you don't let them completely die. If you've ever wondered why they will still tell you the battery is "dead" when trying to power it on after it dies, that's because it's not "dead" so to speak, but the phone shut off to prevent damage to the battery.
In short, letting your phone die CAN harm it, but usually, it won't, because phones power off with some power left in them due to a "dead" battery, to protect the battery. This is why once they die you can still hold the power button and it will tell you its dead. Finally, charging your phone to 100% won't hurt it in any way, as chargers stop charging devices after they reach 100%.

WRONG.
Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage.
Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Too many users have no idea about the facts of Lithium-ion batteries, sadly. Don't spread false information, learn the facts. Charging to 100% IS stressful for any Li-ion battery. The last 10% are the most stressful when charging. That's why Sony invented "Battery Care" which will charge the last 10% very slowly exactly for this reason.

Technically speaking,
A source brought up a couple of months ago says that in a year, approximately 300 charges and/or more, you will lose about 30% of the year. Charging it from 50% and higher will burn out the battery even more. It's better off letting the phone go to a certain threshold of ~>15% of the battery, then charge it so it could have more longer life in these years. Its beneficial for longer life, but day to day wise no. But long story short, i don't really agree with the method you recommend us doing.

This is incorrect. When your phone fully dies then charges to 90-100%, it does a battery cycle. This cycle is worth doing from time to time to keep the safety of your device and battery from not overheating.

I've never heard about it before until I saw it in my S22 ULTRA.
What are the benefits of charging only to 85%? Does it last as much as with 100%?
Does it really recommended to charge it up to 85%? Im not an heavy user, but also I'm not changing my phone once a year, I'm changing it one time in 3-4 years.
Also, I tried to never charge my phone at night, and trying to catch the battery not lower than 10-15 percent to charge.
So basically, it bothers me a little bit in the eye to see that the phone is only about 85%, because that way basically the battery will run out much faster(significantly, yesterday 10% went down in 45 minutes, which means I'll lose 45 minutes from battery usage for nothing).
So, my question is, is it really worth it? Is there a significant difference between the two options? I'd love your help, thank you all!
The 85% is to protect and prolong the battery life. I agree that you will loose 15% of battery time if not charging to 100%. I charge to 100% and when battery is 10 - 15 I charge to full. I guess on the long run it's better for the battery to only charge to 85%, but I change phones every year or 2, so I'm not to worried about prolonging the battery life
Set low limit at 30-40%
Top limit of 72-85% is better.
Li's love frequent midrange power cycling.
Start charge temperature is important to prevent Li plating. Battery should be at least at 72F, 82-90F is better. Cool if charging temperature goes above 99F. Never charge in direct sunlight.
Never attempt to charge at 40F or lower
Avoid having the screen on while changing.
When using, turn phone off if battery temperature reaches 100F or cool it.
Replacing the battery isn't a big deal unless you don't do it on a timely basis. When an Li has reached 80% of it's original capacity it's reached the end of it's useful service life and is degraded.
Degraded Li's are more likely to fail which can heavily damage the phone. Any swelling is a failure replace immediately.
High voltage , temperature and current drain stress the battery. Other than avoiding low temperature charging and going to either low/high extreme voltage ranges constantly I wouldn't worry about it too much.
I now replace my heavily used Note 10+ battery every year or so to avoid another failure, routine maintenance. Batteries are cheap and relatively easy to replace.

So, I understand that it recommended to charge up to 85%? :-D
I searched on google to buy a S22 ultra battery that will keep in home until I need it, but couldn't find one.

If you can last to bedtime on an 85% charge then fine use that setting if you intend to keep the device for 3 years or longer.
If (like me) you need 100% charge to get through the day, continue charging to 100% and dont worry.
I have been using mobile phones for 25 years and I charge overnight as I sleep. I have NEVER had a battery failure or problems.
Life is short, enjoy your new phone
P.S. If you are worried about stressing the battery by charging to 100%, I suggest you also disable Fast-Charging as that is WORSE for a battery cell than 100% vs 85% iMHO.
I used to charge my Note 10+ to 100%, every day plug it while in my car or plug it to my laptop now and then. After 2 years of use battery health was 89%.
On my Lenovo laptop I stop charging at 60% as suggested by Lenovo vantage. Bull****. Battery lasts a lot less after one year. Almost the half.
Enjoy your gadgets and mobiles. Anyway after 2 years most of us get a new one.

how does one set low limit?
i have a smart plug i use for my charger, only on long enough to charge phone from 20% to 85% (battery setting limit enabled).
i usually charge at 30% to 85%.

I just do it by eye. It's not rocket science.
Accubattery lets you set an alarm if you want.

Keeping a spare isn't a good plan as Li's start to degrade as soon as assembled. So after a year or more of sitting there it will have lost some of its initial capacity.
They should became easier in the future.
Any solution to modify the protect level?
"protect battery level 90%, 95% mod instead of 85%"
85% seem to be very short time of using
For anybody wanting to change the limit from 85% to lets say 90%, you can use the App called Galaxy Max Hz, you can find it on this forum : https://forum.xda-developers.com/t/...ods-qs-tiles-tasker-support-and-more.4404929/
One of the options is to change the battery charge limit, on the lock screen it will still say : "Charging stopped at 85%" even though the battery is at 90% as set in Galaxy Max Hz

85% is actually rather on the high side. Either correct the excessive battery drain or replace the battery. When an Li reaches 80% of its original capacity it's reached the end of its usable service life. It's degraded at that point. Degraded Li's are much more likely to fail. Any battery swelling is a failure.

Actually, the protection level should be 80% or less to maximize the battery’s useful life.

I use the 60% protection on my Lenovo as they suggested and gess what, after 8 years my battery still works fine, and lasts for 2h/3h. I used my laptop every workday on heavy use, and it's the most cheap line, it cost me 300€ in 2015 (Lenovo G50-30 Celeron N2840). It's all day pluged, but when i need to use on battery it's fine!
So i realy think this battery protection works, and my S22 Ultra it's for last at least 5 years, and the 85% it's enough to run my workday.

Maybe. Depends on usage. On my N10+ which is heavily used with frequent charge cycling from 40-60% to 72 to 85% most times I get about 2 years out of a battery. Higher battery temperature shortens the lifespan as well. Fast charging is more stressful as is using the device right after a fast charge. High current drain while in use is also stressful; optimize the device to increase SOT and battery lifespan.
Frequent partial charge power cycling can extent the typical 200 full charge cycles to 800 or more. A partial charge is not a full charge cycle.
Start charge temperature matters.
It's an electrochemical reaction, heat is required for it to charge properly!
-//-
Never attempt to charge if near freezing
Fast charging will not engage if battery temperature is below about 55F to protect the battery.
Charging below 72F or above 103F can cause Li plating which will permanently degrade the cell.
Optimum start temperature is 82-90F, cutoff is 100-102F max. Cool if needed.
Regardless of service time replace the Li when it reaches 80% of its original capacity. At 80% it's reached the end of its service life and is considered degraded. Degraded Li's are more likely to fail
Any swelling is a failure and it can destroy the device. Battery replacement isn't hard or expensive. Just part of routine maintenance...

Here is a good article why it's recommended to not load the batt to 100%
How to maximize battery life: Charging habits and other tips
If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.
www.androidauthority.com
Personally i just keep the load between 65% and around 20-30%. Only if i know that i will leave the house longer than 4 hours I do a 85% load or 100% if i want to film and take photos. But this rarely happens.
