Hi, My old Li-Ion battery was starting to losing its charge very fast, so I decided to buy a new battery. I replaced it with a Lithium Polymer battery. Seems to work fine, but....
In the Power settings, it still identifies the battery as a Li-Ion one. How do I tell it that it's now a Li-Pol battery? I tried to search and search, but couldn't find anything.
TIA
Read where is says LiPo on the battery itself.

Not quite sure what you are trying to get at. Do you mean that a Lithium Polymer battery is actually a Lithium Ion Polymer battery? The battery actually only says Li-POL and nothing else.
Does that mean it always says Li-Ion, even if it's a Lithium Ion Polymer battery?

I was curious about the discharge cycle when trying to get battery calibration stats. Does it matter if you use the phone regularly, or should you "beat it up"? Didn't know if that would skew the results.
Also, in doing some searching, I've seen some people mention that fully discharging the battery is a bad idea because of damaging the battery or reducing it's lifespan, which is obviously a direct contradiction of the whole calibration procedure. Anybody have any thoughts on that?
Thanks!

I would just use the device normally.
As far as damaging the battery, it isn't going to happen. The people that say you will damage the battery by fully discharging it don't understand the modern Lithium Ion/Polymer batteries. Batteries now days have over current, over voltage, and over discharge circuitry either on the battery, on the device, or both.
When your Xoom says it is at 0%, the battery is not really fully discharged. It is at, let’s say 3.1 volts, which is far above the voltage (around 2.7 volts) required to damage the 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.

I read so many thread that indicate Nexus 4 poor battery performance. Therefore, I start thinking if I have the correct concept of charging a lithium
polymer battery. I don't know if the article I found correctly indicate the fact. Here is my way to charge my nexus 4 or 7
1. I never let my battery drain to zero or shut itself down. I usually charge when it's 10% or over 5% (How's your view about it? too low?)
2. I rarely fully charge my phone to 100%. I usually get it done around above 95.
3. I "turn off" the device while I'm charging. In this case, I turn off Nexus 4 and 7 when I need to charge them.
4. I rarely charge my phone overnight...( any second opinion on this?)
Any views and suggestions are all welcome. I just try to find the best way on how to "correctly" charge our nexus 4 lithium polymer battery.
Here is an article I read as an example http://buychargeall.com/cellphonebatterychargertips/

Lipo batteries do not need priming as it does not have memory.
Even though it's about Li-ion, effectively they're the same thing.
The lithium-polymer (LIPO) is a more technologically advanced version of a lithium ion (Li-ion) battery. It's electrolyte is held in a solid polymer film which is directly bonded to the lithium electrode.
Charging a drained battery will shorten the battery life. So I would recommend that you charge more frequently, than charging after the battery is low.
Just charge it however you like and don't worry about it. You'll likely have a new phone before any noticeable damage is done to your battery

Sorry, I just have one more question after reading the guide...
So, it's ok to charge over night? Is it ok to always put the phone on charger?
I always charge it when below 5% juice is left. And I let it charge till it hits 100% mark. Plus I put it on charge when I got to sleep and wake up after 3 or 3.30 hours (yeah, thats how long it takes to full charge) then turn the switch off and go back to bed.
Is it ok?
I have let all my devices in the past 3 years charge continuously overnight and have never had a single problem

This. There is nothing to worry about, other than ignoring the many myths that you can read on this subject. The battery will turn itself off way before any chance of damaging it.

Because deep discharging is bad for all lithium based cells non of them allow the battery to discharge to zero, when the cells hit zero in your phone that is the empty limited deemed as safe by the manufacturer and not that the cells are depleted, conversely you cannot over charge it either, Lithium based cells have circuitry embedded in them to prevent damage. Therefore I charge and discharge my battery as i see fit to suit my needs be it over night or a quick blast.
I recently went on a trip to Belgium and it was a 14 hour ferry crossing of which most of the time the phone has no signal. Presumably my N4 was searching for a cell most of the time yet at 17 hours after unplugging it there was still 86% battery left.
People need to realise it is using the screen more than any other single activity that uses the battery, the Nexus 4 is no worse than any other similar phone with a similar battery.
The first phone i had which had a lithium battery was a Nortel 2000, this was in 1996 and i didn't give a toss how i charged that up and i didn't damage that battery, i am sure the technology had advanced shed loads since then.

Nothing here about control live by the phone. I post this only to find out the correct way to charge lithium battery.
Thanks for all the information.
As we know our Z3 has a Lithium-Ion energy supply. There is a really nice site about charging Lithium-ion batteries, chargers and a lot more.
And I want to share this wonderful site with you here on xda: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
so like is it ok to keep the mobile charging overnight???
Yes it is, and has always been with lithium ion. Draining your battery makes the life span even shorter

Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime.

After reading this there should be a little damage because the stress we cause with the full charge. But I guess the damage isn't as big in our case.
Well batteries have a regulation circuit to prevent that and some phones automatically discharge a little automatically after reaching max charge. Don't have to worry to much about that these days.
A good point for Li-ion batteries. Good thing to know.
I'm using Resurrection Remix (i9505) and i want calibrate my battery (with root). Can anyone say any app and the steps to calibrate ?! Sorry my bad english :cyclops:
Battery calibration is just a myth.
I did it on my old phone and there was absolutely no difference between calibration and no calibration.

I'm asking because i bought a Samsung Portable Charger (2.100mah). The Galaxy S4 have a battery with 2.600mah. 2.100 is 80% of 2.600. But the Portable Charger is charging 95%, so i think it's a software problem.
The battery is polled for its vital statistics by the device. The device translates what it receives from the battery's internal circuits to a percentage, which is reflected in the status bar. All battery calibration apps are useless for two reasons. The first reason is they don't recondition the battery. To do so requires expensive hardware, since this is a lithium ion battery we're talking about. The second reason is that they delete the batterystats.bin file within Android. Deleting that file isn't going to do any harm, but that file is deleted upon the battery being fully charged and disconnected from the charger.
Battery calibration is useless. Any positive results are from the placebo effect.

Then let the battery get to 0 and charge to 100. That's the most reasonable method. Any other app just deletes the batterystats, which also gets deleted whenever you unplug the charger from your phone.

Make battery from 100% to 0%. Don't turn on phone until it gets 100% battery. Then use an app called "Battery Calibration" by Miroslav vitulea.
@gosha98_: Draining the battery to zero will not reset the battery. In fact, draining a lithium ion battery to zero is dangerous, as at zero percent charge the battery becomes unstable and may explode. Back in the era of NiCd and NiMH batteries, draining to zero could in fact "reset" the battery, but not today with lithium ion.
Using a battery calibration app prior to removing the battery off charge will not hurt the phone or the battery since all battery calibration apps do is delete the batterystats.bin file in Android. But, it will not help either.
