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.

Silly question, but thought it would be good to ask nevertheless,
Does Adaptive Fast Charging Reduce the Lifespan of your Device?
How is the impact on the overall number of charge cycles for the removable battery?
it reduces the lifespan of your battery not your device. charging at anything exceeding 1C damages the battery. thats 1.5 hours for a full charge.
then again the battery is 30 bucks.
Let the battery drop to 2%, then let it recharge!
Over time, we all know that most batteries lose a lot of their useful juice.
>> I'd suggest making the battery life-life last longer, by letting the battery drop to 2%, then, recharging it fully! This is to avoid battery swelling in the phone, which may cause an internal damage to your phone's components :good:
Happy browsing!

Isn't that too low? Won't doing that actually reduce battery life in the long run? I've read that it's good to let it drop to 20% before re-charging it.
Analogy time!

Let's imagine you were a phone that was used the whole day, and your batteries are down to 2% Let's say that 2% is your subconscious, to run all that extra information that's through your brain, telling you "Hey, you got extra (at 20%) a whole lot of space for new power juice!"
I know it's sounds like a very childish analogy, but I guess this is the best way I could've explained it :fingers-crossed:
Best information source on batteries:
http://batteryuniversity.com/
The batteries degrade as a function of discharge cycles (where 10 discharges to 90% are roughly the same as one discharege to 0%), time, temperature and charge.
Batteries age slowest when they are at 40%. That's why your out of the box battery is usually 40%, to prolong shelf life.
Batteries age faster the higher the temperature is - adaptive charging increases the temperature while charging more than normal charging, but not by much nor for a long time.
So no need to worry about anything. Charging from 2% is not better than charging from 20%.
Note, their article http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries does not take into account the adaptive charging technology, so the last graph is not really applicable in this case.
I don't like quoting batteryuniversity.. but this is pretty good analysis.. Depth of Dicharge is directly related to the overall longevity of the lithium batteries.. more you discharge.. the less cycles you're going to get..
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
but.. considering that these batteries are $30 bucks.. use them how you like.. just replace it when you start to "FEEL" that battery isn't holding the charge anymore.
The only thing that Samsung said about the Adaptive Fast Charging adapter is that you can charge 50% of the whole charge in only 30 minutes. They didn't say what tecnology they used or any warning of it. If you buy a phone, and it cames with the original charger which is aproved by the FCC and who knows what other organizations tested it, it means that you will not have any problem with the battery by using the original charger that comes with your device. Anyway, a normal smartphone battery only lasts it's original capacity for almost 2 years, after that, consider to replace it.

so how much "C" this adaptive charger Note 4 ?
As far as I know modern phones know how much juice is in the battery, and shut off well before the battery is empty to ensure no damage is done if you drain it completely.
With all my new phones I always run them till the turn off then fully charge them back while off up to 4 or 5 times, and in the past this has always improved the life of the battery.
I do not believe this improved the battery life of modern phones though, it's just a habit.
On the flip side, it's never damaged a phone or battery of mine.
As for charging currents and speed, i've always used used charger 1.5amp and above and never had a problem.
Using always connected to Charger?
For long term battery health I wouldn't recommend keeping it plugged in for long periods of time. People say today's batteries have protective circuits that prevent overcharging, but I don't really trust this. So I simply unplug it as soon as it is fully charged.
As for actual better battery life, turn off everything you don't need - GPS, Bluetooth, Wi-Fi, Mobile Data etc. This phone should give you an average of 6 hours SOT. To obtain more you will probably need a custom kernel, but even then the results may vary.
Yeah it has protection circuit to protect overcharging. Lithium based batteries can always take charge, and might self-combust. (ok , worst case. basically, lithium can't get in contact with water. RH in air is just enough to start the self combustion reaction). Nowadays, Li-ion or Li-Po are well made, and this is less problematic.
This as been said, it doesn't mean that this circuit won't trigger the battery every 0.XXX% drop, which is not good, so yeah, until someone do electric reading test on the op5, I won't suggest to let the device plugged in when full.
Simple rules for lithuim based batteries :
- time will kill the battery, even if it's brand new sealed. (normal chemical reaction). Nothing we can do here, limit extreme temperatures, not too cold not too hot.
- heat will decrease battery life and capacity. This mean, dash charging will decrease life. So, 1.2A to 2.0 [email protected] charger is more appropriate. Even if dash tech will regulate the charge, you still have a time that it will optimize to max power, so more heat.
- Polarity direction changes will decrease life/capacity. This mean, do not charge it if you don't need to.
- do not wait to drain it at 0%, I don't know what is the security factor from OnePLus. A single lithium based batterie under 2.60-2.75V, will mostlikely be dead , or will loose more than 50% of his capacity.
Some lithium based battery will perform better, but to keep low price, do not worry, oneplus use standard li-po.
More developed info here :
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
When the phone is plugged, it doesn't use the battery anymore, therefore the battery is not drained. Once it reaches 100%, it just stays at 100% until you unplug it.
Some says that leaving the charger plugged is not ecological, because it still uses energy even if it doesn't charge anything, but in reality it hardly use energy. I don't remember the numbers, but it is really insignificant.
In the end, there are a lot of superstitions concerning charging and battery life, most coming from old habits and false/outdated information spreading through the internet. The only things very true is that you should avoid letting your battery going to 0%, and don't let your battery overheat, and that's all. Charge when you please, as long as you please, and avoid using low-cost chargers or batteries as some can be dangerous.
I used my Xiaomi Mi3 for 3 years, letting it plugged every night with a QuickCharge charger, and it could still handle a whole day when I finally sold it.
not talking really about sot here, but about the battery health over months/years
I can read some posts where people report a very bad sot, when the Z play is normally a very good device regarding battery, There are several possible causes of course, the rom, the apps used... and battery degradation over months.
According to a studie, a lithium ion battery loose 10% every 250 charge cycles, there is some rules to help to not loose more :
A partial discharge reduces stress and prolongs battery life.
- avoid charge over 90%
- avoid use below 20/15%
- Battery lithium ion hate heat, so when charging avoid use your phone, can add heat from cpu mostly with games, and you will charge/heat longer
- the turbo charger make the phone heat like hell, and again lithium ion batteries can't stand the heat, it's a fact, Somes will say it's normal because it is sold like that. I won't take the risk if not needed, so i use only the turbo charger when urgency, otherwise i use my lenovo tablet charger (5,2v / 2A), that charge quite fast too with no heat at all.
I wish there was an option to turn off fast charging like on Samsung phones...
I don't know if we got different phones, but I always charge phone with stock turbocharger and its never hot - when I'm not using it during charging is not even warmer than normally, when I use phone during charging it's little warm.

really ?? mines heat a lot too with turbocharger and without using it during charge
Mine too, but i put it on the stone cold floor and it's much better. You should do this.

I suggest following[1] battery charge limit app ... It works fine ( root required )
[1]
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002/
or just use a regular 1A/2A charger at home and only use turbocharger on the go
I've also done research into this, as this is the first phone I want to keep more than a year and a half. My conclusions from multiple sources are as follows (quite similar to your findings):
- Don't charge over 90%, but really you shouldn't charge past 80-85% (choose your percent based on how much you will need for the day)
- As you said, don't go below 20%, but really you shouldn't go lower than 40%.
From what I can tell, the 80-40 rule seems to be a legitimate and fairly reliable rule of thumb for smartphone batteries (don't go below 40%, don't charge past 80%).
Battery University has a lot of good info, and they state that smaller discharges and recharges are generally better for the battery. I've been able to get a full day or two of usage from my Z Play by starting with 90% and not going lower than 35-40%.
I've got an issue with my battery where phone shuts down every time at 30% and won't charge above 80% unless I disconnect and reconnect charger then charges rapidly to 100%
I've heard LiPo batteries are easily damaged and have a short life span. In my case it has came to 0% numerous times. I tried calibrating it and still nothing
Here is some info on the battery.
Are those mA measurement's okay or bad?
These measurements are totally normal
It's probably your rom mate

Sounds like you need to return it under warranty.
Well I tried many different ROMs and stock firmwares still no luck. I've called service center and they will fix it. I think Li-Ion batteries are far better then Li-Poly
Had that issues on my previous device, Galaxy S4. Shutdowns at ~20% battery, terrible sot. My battery went bad so i replaced it with new battery and that solved it.
Consider replacing battery if flashing stock firmware does not help.
Batteries can last long if you take care of it. I guess you tortured it by draining it all the way to 0% or using the phone while its connected on charger, you should NEVER do that! 20% in my opinion is minimum before you should charge it to prolong battery life. Also if you really want very long battery life, do not charge it above 90%.

Thank you, I will be sending phone to service center. I really was using it while it was charging and it went to 0% million times.
This is what you guys get with a bad battery

How long have you had the phone? I doubt li-poly batteries is alot worse than li-ion since both are very similar.
