Tips for Battery saving and for a Healthy Battery

HELPFUL TIPS FOR YOUR NEW BATTERY!
Initializing your new battery
When you got a new battery, insert it into your electronic device. Turn your device on and drain your battery until your left with 1 bar of power. Then charge your device for a minimum period of 12 hours. Your 1st charge cycle is very important, do not charge it before it's down to 1 bar.
Recharging your new battery
After you have completed the initial charge, your battery should only ever be recharged once you drain if down to 1 bar of power and should be recharged for a minimum period of 6 hours for the battery to reach its full capacity. Ignore the phone telling you that the battery is full - this is normal but is not accurate.
Avoid fully discharging your new battery
Your batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left.
Battery care tips
Charge your battery correctly by using appropriate charger and drain your battery up to one bar before charging.
Keep battery contacts clean to effective deliver power in your device and optimize battery life.
Lower screen brightness/backlight and disable custom animations/transitions to lower battery consumption.
Avoid using unnecessary features and close idle applications running in the background as they still consume power.
Use GSM rather than 3G or Dual Mode as being on GSM mode consumes less power.
Turn off Wi-Fi or Bluetooth connectivity when not in use as they consume a lot of power.

Can you site credible sources for those battery charging "tips"? As it sounds like a myth from way back in the NiCAD era, rather than modern LIon batterys with decent charging circuits.

I'm also curious about hard facts.

http://www.androidauthority.com/the-top-3-android-battery-myths-46924/
Devices nowadays have transitioned from using nickel-based batteries, to lithium ion batteries in the past few years. Until now, myths associated with batteries are yet to be disproved however, there are studies and experiments proving that some of them aren’t entirely true. While nickel based batteries indeed have their own problems back then, lithium ion batteries, which is commonly used to power up laptops, cameras, and phones to name a few, are always filled with myths that most techie people still believe in.
Below are the three battery myths that have already been disproved.
MYTH NO. 1: New batteries need an initial overnight charge
This is one of the most untrue myths about lithium ion batteries that a lot of people believe in. When opening a newly purchased device, you DO NOT need to fully charge it initially. Although there are benefits offered by doing so, initial charging or ‘priming’ does not affect the battery life in any way.
Manufacturers strongly suggest users to do this so that the battery will be properly calibrated and the power indicator will display the accurate battery life of the device. However, there is no need to worry about using your gadget fresh out of the box because even if the calibration is incorrect, which rarely happens, it will fix by itself over time.
MYTH NO. 2: Overcharging your lithium ion battery will reduce its battery life
One of the most common myths that we have heard about lithium ion batteries would be the need to plug it from its charger after being fully charged, since overcharging the battery/device will reduce its battery life. The truth is, lithium ion batteries cannot be overcharged or can be reduced of its battery life through overcharging. What’s good about these batteries is that that already have built-in circuits that will cut off the power once it has been fully charged.
However, it is a good idea to unplug or remove the battery once it has done charging because the heat from poor ventilation or from charging will cause it to blow up. Another reason why this is an important note worth remembering is that batteries discharge faster when heated thus, reducing its lifespan.
MYTH NO. 3: You can calibrate your Lithium Ion battery every once in a while
Some of the rechargeable batteries being used today have a battery memory. Some batteries will slowly lose their maximum capacity if you fail to completely discharge it plugging it in. Hence, recharging it while it is still 40% charged will mark it as the new 0%, which gives you lesser capacity for your battery. However, this only applies to technologies applied in older batteries but isn’t applicable to today’s lithium-ion batteries.
What you have read above hopefully in one way or another, eased your worries about decreasing your battery’s lifespan.

Some more (generic) information about lithium-based batteries (sorry, not allowed to post links yet):
batterycare.net/en/guide.html
micro-power.com/userfiles/file/mp_tempcharge-1250026530.pdf
batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
All of these show heat as an important factor in capacity loss. You might be able to reduce heat from external sources, but as the chart in the pdf shows, the battery itself produces heat while discharging. With a constant load, the generated heat goes up rapidly after the battery reaches around 25%. As there is no memory effect in lithium batteries, it seems best to avoid this area altogether.
Of course, the maximum capacity will decrease with time regardless and a calibration cycle (100% to near empty) once in a while can be useful to ensure your battery indicator is reliable.

Ways to Protect Life Span of Samsung Galaxy S i9000 Battery

Many people just think about how to protect the Samsung Galaxy S i9000 battery life of phone, today i introduce some experience to protect our phone battery, so that we can save the battery life from these ways::highfive:
1. Fully Charged
To maintenance of a lithium battery, must occasionally let one of the electrons to maintain liquidity, to ensure that at least once a month to go through a full charge (battery is charged up about 20% full).
2. Do not use non-original straight and "universal charge"
Because the third-party charger specifications and quality can not be guaranteed with the original charger, battery might be damage repair may also cause disputes.
Why rushed 100%, they still continue to charge?
Power to 100% does not mean that your battery is already full. To Charge Gauge maximization, and roughly 40 - 80 min rushed fully full of From 100%. If the battery is aging, which will require more time in waking this process.
3.Do not drain the battery.
Try not to use automatic shutdown on the line, often run out of battery power will affect the battery capacity and charge cycles.
4. Do not overcharge
Stop charging long after the battery has been fully charged phone prompts, 40 to 80 minutes.
5.Note heat
Please keep in charge when the phone is easy to heat the place. Because the battery charging will occur.
Today, i just write thess ways to help you guys protect the cell phone battery, just do hope it is a help to you!

If you charge the phone while it's turned off it shouldn't overcharge anyway.
It charges to 99% then stops automatically. So you can leave it charging overnight without damaging the battery.

I'm sure there are some others doing the same...

Recharge Early prolongs Battery Life
It's absolutely impossible to Overcharge a Lithium Ion Cell with the Stock Charger, despite of On/OFF State of the Phone so don't worry. A Lithium Ion Cell would degrade a lot (permanently) if you'd overcharge it but this is really not a Problem those days, because the Recharge Process will surveilled by a seperate Microprocessor to avoid any overcharging. In my Experience it is much better only to recharge the Battery ONLY when the Phone Power is Off- that's what every Manufacturer writes in the User Manual. Me personally using a Universal Charger with a second battery, so i can always use the Phone and the USB Connection will not be stressed. Also i am recharging early- that means a Battery Level from 30-70 %. If you recharge when the Batttery Level is about 3.7 Volt recharging goes much faster and the Battery will not be stressed that much like when you run it till it's completely empty- that should implicitly be avoided!). It's NOT necessary to decharge completely- o.k. If you don't do that from time to time it affects the shown Battery Level a little bit but if you recharge early and often this is not a Issue at all.

I run battery cycle from 25% to 80%. I keep it between these levels. It is good for Lithium Ion Cell batteries as neither cell is empty. If it gets empty, impurities settle on the anode/cathode.
There was an app which allowed limiting max charge. Was it NSTools or something on those lines. What was it called? *scratching my head*

New s7 battery conditioning

Hey guys, I recieve my s7 edge today, whats the best way to condition the new phones battery? Some use what it has until its low to recharge until 100 others leave phone off and charge to 100 at start, whats the best result for a good healthy battery?,
Thanks

Lithium ion batteries have come a long way. There is no "memory effect" and conditioning is probably not really all that necessary. If I were you I'd just give it a charge to 100 and use as normal. Might have high drain for the first few days/charge cycles.
Remember that with Li-Ion batteries a "charge cycle" is one complete cycle from 0% to 100%. So by charging when it's at 50% you're only using up one half of a "rated charge cycle" - Battery conditioning shouldn't really be required with modern lithium ion batteries.

Battery conditioning isn't necessary but charging fully and depleting fully will help the phones software learn the battery capacity and give the most accurate percentage remaining reading. I'd say do this a couple times after you first get the phone

This makes sense I guess. But wouldn't the battery percentage remaining be based on the voltage in the battery at a given moment? I wouldn't think the phone would need to "learn" that.

Afaik. It's actually bad to discharge li-ion and li-po batteries down low. I think it's better for battery health to recharge around 50% for instance than waiting until 0%.

The 50% mark is an old(and still good) rule of thumb primarily for lead acid batteries.
Leaving these batteries in a discharged state can be bad for them, but in normal usage even a discharge to 0% is fine if followed shortly by a charge cycle. These devices have a low voltage cutoff which is what shuts the phone down and protects the battery from over discharge and damage. Bottom line is use and charge it however you like, the only thing that may change is the time it takes the software to learn your discharge profile and show accurate stats.

This makes sense. The article I read awhile back was likely referring to non smart charging systems, such as a battery pack. It makes sense that an integrated solution such as a phone would regulate that to maintain battery health.

There are three things that are very bad for Li batteries. 1: overcharging. 2: completely draining. 3: overheating. Li batteries are happiest, and will last the longest, if never cycled above 75% or below 25%. Cars like the Tesla actually show 100% charge when the battery pack is only about 75% charged, and show the battery as depleted well above 0% charge. Then again, the battery pack for a Tesla costs a lot more than a phone.
#1 shouldn't be a problem in any modern device. The circuitry in the battery will tell the phone when to shut down charging to prevent overcharge. #3 can be a problem. If you're charging the battery simultaneously with high battery draining phone usage (e.g., GPS and Nav) phones can get very hot. In fact, I've had my phone stop charging and display a warning when I was navigating and charging the phone wirelessly at the same time. If you're using GPS on a long trip, you almost have to charge it while in use, but might want to avoid wireless or fast chargers. Wireless chargers and fast chargers generate more heat.
#2 is up to you. Repeatedly discharging the battery to single digits will reduce it's lifespan. I try to recharge before 25% but if I get into a situation where I can't I don't obsess over it. I don't worry too much about charging to 100%. I suspect that, like Tesla, 100% is probably not really 100%. The battery manufacturers are likely to leave a little safety margin in there to ensure batteries can't overheat and catch fire.

#1 -> Could be a problem. Manufacturers can set the 100% mark at higher voltage to make it look like it has more capacity while sacrificing longevity, just enough to get through the 1 year warranty period. (Lot of powerbanks do this!) Users have no control of this ceiling. Charging to 80% and letting it cycle below that probably keeps the battery much healthier than keeping it plugged overnight at 100%.
There's an app called AccuBattery on playstore that people might want to check out. It's basically an alarm that turns on when the battery is at desired % level. It also cites real research papers so I would trust what they are doing.

I used to have a long post with a detailed technical explanation but lost it.
Anyway the gist is, basically, batteries work by ion movement, and like a machine, these ions wear out over time due to use. And similar to machines, heavy use wears them out more. You're more likely to break an engine by running it for 1 day at max rev, than running it over a month at half capacity. The smaller the depth of discharge, the lower the wear. Lab tests have concluded that when you constantly discharge from 100 to 0, it allows you betwrrn 300-500 charge cycles before it starts to break down and not hold charges. More specifically, when you reach that magic number your battery can only hold 75% of it's original charge. That's typically 1-2 years of use if you charge once a day. And heavy abusers charge more than once a day, so that decreases the time span to however many weeks it takes them to reach 500 charge cycles. Now, the increase in charge cycles is exponential, not arithmetical. So a depth of discharge to 50 before recharging will not give you 600-1000 charges. Rather it will give you 1200-1500 charge cycles. Mathematically, draining a 3600mah to zero for 300 charges gives you 1080000mah to burn through however short your battery life will be. On the other hand, using only 50% of the battery before recharging gives you 2160000mah to burn through before it expires after at least 1200 charge cycles. In other words, it stored twice more power for you to use. If you say, charge once every 24hrs, going always from 100 to 0 gives you at least 300 days. Recharging twice a day at 50% gives your battery at least 600 days of use before battery capacity deteriorates noticeably. Discharging to 75% before recharging actually gives you 2000-2500 charge cycles, making it even longer. Basically the point is, always plug the phone in when given the chance. Don't wait for 50%, or whatever. 40% is an arbitrary number actually, not sure why it's chosen. Also, this is why one of the choices to auto activate power saving in the S7 is at 50%, so that it keeps the battery up as close to 50% as possible when you get the chance to plug in.
As for charging to 80%, this is because partial charge is better than full charge for lithium ion batteries. The ions are placed on stress to hold charges. Maximum stress is at 100% charge. And like everything else, stuff tends to break more. So not running it to 100% all the time will reduce overall stress experienced and increase the time before deterioration occurs. Personally I charge to 90%, and discharge to 40% or above. That's a 50% depth of charge, so that's good for up to 1500 charge cycles, plus whatever number of cycles the decrease in max stress gives me.
However, note that environmental temperatures also play a role in battery longevity.

That's actually a perfect way to ruin your battery on purpose!
Just do these things and Don't worry a lot. And remember, when it does die it's not your fault, it's kind of a problem with Lion batteries!
1. Try to keep the battery between 40-80% or 20-40%. But don't worry if tou can't. Saying this in case you're staying at home all day.
2.Keep the heat away from it!!! This one is important
3. Try to discharge it at a lower rate but don't let that get in the way of you enjoying your device.
4. Try not to discharge below 8% at all. But try to not discharge it below 15-20% unless you have important things to do.
5. don't keep it topped of for a long time (like constant going 90-100%, this is damaging) and don't keep it at 100% for long! (For example turning it off and stop using it for a week, or keeping it plugged for a few days)
If you're storing it keep it at 40% (3.8-3.75V) and try to drain it once in a while. (Unlikely to happen with a phone specially one without a removable battery )
I really do hope someone invents a new type of battery. Lipos are anoyying

Simple you don't need too lol

Battery Charging Voltage too high?

Ive bought my n6p a few days back but is already a second hand.
Though its in perfect condition I would still love to take care of the battery since I know theres been a large chunks of battery cycle depleted already.
An average li-ion has about 300-500 charges before battery shows signs of deterioration.
In order to increase the battery life cycle, charging it with only 4.05 volts as conpsred to 4.20+ is the best way to take care of li-ion cells.
The problem is, the charger that comes with n6p produces volts from 4.16 as the minimum up to 4.4+ which is basicslly dtressful to the battery, plus letting it be plugged in to 100% increases temperature and so on.
I can go on.
Now, I have the habit and got an app that will chsrge the battery judt to 78% or 85% which turns down voltage just below 4.2, however there sre still instances that the voltage goes more than 4.2 even though im using a standard 900mah charger and not the rapid charger (original usb cable from huawei type a-std)
The question is, is there anyway to turn down voltage for n6p?
If not, any electrical engineer or anyone who has great knowledge backed with experience here to tell the comunity if chsrging in 4.2+ v is safe for n6p and why? Thanks

Charge voltage above 4,23ish is not good for lithium battery cells. Mine has a reported battery voltage of 4,4 volts.(!!)
As to the actual science of overcharging/over-volting lithium batteries, I don't think there's any long term 500-1000 charge cycle data. I do however have experience from radiocontrolled 1/8 scale lithium powered cars. Absolutely none of the lithium battery sellers or charger manufactors​ approve charging over 4,2volts. If you have a higher end charger you can push them to 4,25v-4,35v for cheaty improved off-the-line race starts but the charger will beep and complain/warn you constantly about the risks.
I was slightly concerned about charge voltage aswell, optimum charge modes for lithium cells are constant current ie 1800 mAh for this device until battery reaches 4,05 ish volts then constant voltage until 4,2v but it seems that phone manufacturers are either calibrating the measurement data or pushing the charge rate for convenience. If the latter is true you have all the right to call it planned obsolescence if the non-existent science of overvoltage charging is correct. The most accurate way to measure battery voltage would be to probe the battery directly while charging and while fully charged with a digital multimeter

Li-Lion Battery - Fast Charging

HI All,
I have a new moto g7 power which supports fast charging.
I want to prolong battery life and maintain the battery for as long as i can.
The instruction booklet says to charge it with the fast charger supplied only.
From my research it seems that li-lon batteries prefer top ups and to be kept between 40-80%
Also I never realized that first charge should be all the way to 100% not sure if I did this, have I harmed the battery if I did not ?

as far as I know, lithium likes to be between 85% and 15%. anything below 15% and above 85% is potentially bad for the battery, assuming 3.7v is 0% and 4.2v is 100%.
