Any need to recondtion battery?

I have a couple of extra stock Samsung batteries and am using the wall plug in charger from Fommy.com to charge my spare batteries. Everytime my battery gets to 10% , I just swap batteries and throw the low battery on the charger. I haven't plugged in my phone for a couple of weeks now. Does this do anything to my battery or the way the phone reads the power?

After every flash recondition.

No need to recondition if you use multiple batts. You will never be totally accurate. It really doesn't effect your battery use.

How do you first charge the Nexus 4 for the best battery life?

I remember as a kid, when getting new hardware, you need to charge it to the maximum and leave it in for a few hours to kinda work the battery and get the most optimal battery life. So for this phone, what would you need to do when you first get it to get the battery to be the best it can be?
Do we cycle it from 0 to 100, or just charge it to 100 and leave it?
Or does it not matter?

It doesn't matter. While older nickel-cadmium batteries could have issues with charge memory, lithium ion batteries are not affected. Just charge and use your phone as normal. If you want to maximize battery life make sure not to place your phone in extreme heat (eg. inside a locked car in summer time) and avoid leaving your phone at 0% charge for any length of time.

For the purposes of this discussion it is identical.

Well technically it's Lithium-ion Polymer

Same thing. Either way they don't have the memory issues that old rechargeable batteries had..

Nope.
These new Lithium batteries aren't subject to any of these myths.
Same with the "Take off your device from the charger once it has been fully 100% charged or the battery will stuff up." Nope. The battery just cuts the charge and just runs down. That's why if you look at your charging history, it might go to 99%, 98 or even 97, and go back up to 100% because that's when the phone decides, "Yep, I'll take a bit more charge."

Alright. Thanks to everyone!
I'm getting mine tomorrow ;D
(Aw, outta thanks to give :'( )

It is good with these batteries to run then down to almost empty every week or so, right?

Another myth. Not true for Lithium batteries

Really? I read this in a battery forum years ago. This was for laptop batteries though..
Not meaning to sound sarcastic, how do you know this? Are you an electronics engineer or something? Just wondering.

Lithium-ion/lithium-polymer batteries don't have the "memory effect" that older nickel-cadmium and nickel-metalhydride batteries did. So there's no point trying to run your battery down low every now and again to help its life. In fact, it seems that charging it more often is the most helpful thing, i.e. lots of small charges rather than big charges all the time.
Just use it normally and charge it when you need, it'll be fine.

How about leaving the phone charging after it is fully charged? Like when you charge it overnight.

The phone and charger electronics will lower the rate of charging as it reaches 100% and turn it off when it's done. You don't need to worry about unplugging it right away.
In longer term storage situations where you aren't using the device (i.e. weeks or months) it's optimal to store the battery at a charge level of 60-70% to reduce battery degradation over time. When the Mars rover \Curiosity was en route to mars the batteries were at 60% and were charged upon approaching the planet.

I am an electrical engineer actually. Li-Ion or Li-Po batteries do not need to be treated any special way. The only thing that degrades them is use and time. And it does not matter how deeply you discharge them (discharging to 50% twice is about the same wear on the battery as discharging to 0% once, within a reasonable degree of error).
What you may have been reading was with regards to calibrating your laptop's battery meter. There is some truth to that, and allowing even your phone to discharge completely (down to 5% or so) once can help make sure your battery percentage is accurate. But it does not affect your battery life at all.

Actually, it doesn't say to do it "first". It says "its a good idea to fully charge *as soon as you get a chance*."
The wording in the quick start guide you provided doesn't seem to imply that its a critical thing. It seems to me that they are putting that there in case someone takes it out the box, starts playing with/using it, then wonders why the phone is already dead. Then they post to XDA about how the battery life sucks. (Just kidding! )

Bad charge ?

Hi,
I recently bought an external Battery, and i'm charging my N4 really often, for example as soon as it reaches only 50%. Is it bad for the battery of the N4 ?
Sent from my Nexus 4 using xda app-developers app

It's actually good for the battery not to go below 20% afaik, meaning this should actually be good for the battery.

Doesn't matter if you recharge at 50% or 1%. The battery will be fine. You will be charging it more often but for less time at 50% so it balances out really. The thing about not letting the charge get too low is a myth, because the 0% on the phone is not really 0% on the physical battery, there's circuitry there to protect it.

So basically, everything ever said about batteries is a myth, and just use them however you like xD

no. you dont necessarily need to chaege only when battery is low. you can charge whenever you want. your choice

Thanks a lot for your answers !

Should we turn "fast charging" off?

I think samsung didn't make this clear at all. And at the moment, I really don't have sure what is the best thing to do. Let this always turned on may let the battery have a decrease of capacity on a period of time?
Sent from my SM-N910C using XDA Free mobile app

No. Remember, the battery has a "safe" range of voltage. Of course I am assuming that even within the safe range it won't degrade any faster.
Also remember, you can just replace the battery!
Sent from my SM-N910T using XDA Free mobile app

I also think this way. But when we let the phone charging overnight, during our sleep time. The fast charging is not necessary. In this scenario, did you still leave this mode on?
Sent from my SM-N910C using XDA Free mobile app

I leave Fast Charging OFF because I only charge my phone while I'm asleep.

I think fast charging is harder on the battery than standard charging but as always, and unlike other phones, we can easily replace the battery in seconds.

Same here, I leave it Off most of the time as I charge while I sleep, and only use it when I need a quick boost if the day is going to be much longer than expected, e.g. if I'm going out after work and not sure if I'll go back to my own place after that.

Fast charge is the only thing stopping me from complaining about the 5hr SOT

Not sure its placebo or not but when i use fast charging i think im getting worse SOT times.

It must be the placebo effect, I am not seeing any diff.

It's a great feature, should just use it and worry about battery life when the time comes. Like others already said, the battery can easily be replaced.

OBVIOUSLY the phone is designed for fast charging at night while we sleep or would you rather believe Qualcomm and Samsung didn't think of that and we now all have a ticking time battery bomb ready to go off at any moment at night....
Oh the horror....

So does this feature make battery life worse?

I dont charge mine over night, but if i did, I would turn off fast charging, or use one of my lower powered chargers. The fast charging is excellent duringbthe day, but using it while you sleep serves no purpose

I tried theboth . I think both of them take same time to be the battery fully charged
Sent from my SM-N910C using Tapatalk

They take the same time to completely charge your device. Quick charge will charge your phone at full speed for about 15mins and then gradually decrease the charging speed so as to conserve battery life. It should not be a problem to quick charge your phone overnight because of this feature.
Sent from my Nexus 5 using XDA Free mobile app

Also it would not be a problem because it doesnt keep feeding into your battery when your battery is full. There ARE safetymeasures, its ultimately irrelevant. I leave it on fastcharging all the time, because theres no reason to turn it off.

Leave it on. It's one of the best feature. Fast charging. Luv it.

Having used multiple batteries, and both fast charging on and off with several different chargers, I can say that it has no effect on SOT. This isn't a thought, I record battery use with and compare the data.

Surely there has to be SOME downside, if they allow you to disable it.
I mean, if there's no downside, why would anyone want their battery to take longer to charge?

How do I test Quick Charge 3.0?

I just got myself a new V20 yesterday. I tried charging it with my own Quick Charge 3.0 wall charger but I'm not too sure about the charge time.
So I'm going to try again. But before I begin, I need some advice.
How do I check if it's really charging with Quick Charge 3.0? Also, the phone now is currently about 66%, how much more do I have to drain before I commence?
Sent from my LG-H990 using Tapatalk

As much as you want. Thing to remember...QC is variable rate, the more charged you are the less fast it is. Also, official posted charge times from OEMs refer to a phone powered off typically.

Right. Powered off. Good point.
And I supposed using an app like "Ampere" is not going to work because of QC3.0's variable voltage and amps, am I correct?
Sent from my LG-H990 using Tapatalk

Okay. Just did a little test.
Started at 5pm with 25% battery left and using my own QC3 wall charger.
Ended at 5.50pm with 91%.
That's pretty fast! And the best part, the battery stays cool despite Quick Charge.
I'm going to try charging from 0% tonight.
Edit - Oh and my phone was turned off while charging.

Just an FYI, it's not good to drain your battery to zero. It'll shorten it's life. Keeping it between 40-80% is optimal from what I've read.
Sent from my SM-T810 using Tapatalk

Ampere app on Play Store, check it's charge current values specially when screen is off. I think it should be like between 2400 mA to 3200 mA. When screen is on , the charge current values decreases. Also with the app, you can compare the current values of QC 2.0 versus QC 3.0. Cable should't be faulty.

Thanks for your advice. I am aware of this. But I want to experiment just this one time. So it shouldn't hurt too much.
And the results are good! 30 minutes and it reaches 51%. 60 minutes with 89%. 70 minutes 95%. And 83 minutes to hit 100%.
Very pleased with the results.

Ampere might not be the best way to measure current values because of the way Quick Charge 3.0 charges with variable voltage.
The few times I measured all fall below 1000mAh.

Hey fellas, not to take over the subject matter but feel like you all know batteries well. What if a 1am charger is used overnight for charging. Going with the idea that a slower charge charges the battery better and maintains a better charge all day, or is that not the case. Also is any harm done with charging with a slower charger. Thanks

I never use quick charge at work or at home, slow charging will prolong the battery life. I always start to charge at about 8-15% where possible, and disconnect the charger around 90-95%, this is the proper way to prolong litium battery.
The only time I use QC is when i'm traveling.

Thank you @kms108 , I use 1am charger for my overnight charging at home overnight. I tend to also stay away from fast charge but wasn't sure if I was doing more harm then good. I do have a quick charge at work that I use for about 10 min before I leave the office.

It is better to use a slower to prolong the longevity of the battery. You won't get more 'charge' from using a slower charge. I try to use slower chargers when I can. I usually use my Samsung 2A chargers and use my adaptive fast charging when I need quickness. The LG QC 3.0 does pretty well though. Battery doesn't get that hot but I'm quite sure it still isn't good for the longevity. Nonetheless, we have swappable batteries so I can use my AFC and LG QC 3 more often lime I do my note 4. My HTC m8 and moto x pure usually were used with 1A chargers most of the time unless I needed a super fast charge. Also, LG makes quality batteries. Probably why Samsung is switching to them until they figure out what the hell they did. Also, notice apple doesn't use quick charging technology. iPhone's battery tend to hold charges better until a out 18 Mo th period before user starts noticing appreciable decline. The peeps that put iPad chargers on iPhone's will see less longevity from their battery.

So I thought that QC3.0 was supposed to get you closer to 80% in 35 minutes, vs the 50-55 from qc2.0. So I also read that the factory charger that LG sent is a QC2.0 and not 3. So I bought a 3.0 brick and also a new usb c that is certified compliant with QC3.0. Still only got to about 40% in 30 minutes. Not sure what's going on with that. I understand longevity and all of that. However I got this phone because once my battery is shot I can just swap it. So I don't mind getting that faster time and buying a newer battery a bit early.
