Think one of our wonderful devs

Can get our batteries to charge faster? Or is there really no way....
Thanks for your responses

Use a more volt charger? Idk

charge it while it's on 50% or more. lol
the external charger from samsung charges faster than charging it on the phone.

From what I understand, faster charging equals shorter battery lifespan. I'm sure it's possible though.

Usually when im charging if I reboot my phone while charging itll boost the charge some.. don't know why, but I usually gain about twenty percent or more at the least. Also charging it while powered off is generally faster for me.

rebooting it could change the battery estimate, which is what "conditioning" the battery really does-- it changes how the battery level is estimated by the system and not how the battery actually charges.
I'm guessing that the reboot causes the system to re-estimate.

It's inaccurately boosted and if you take it off the charger at that point it will drain extremely fast.

Reason being is this phone charges slow compared to others

I bought 2 spare batteries and a charger. Ebay from China. Very cheap and works like a charm.

Yes. Its possible. You would need a new kernel.

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.
Sent from my Nexus 7 using xda app-developers app

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! )

[Q] Brand new N4 battery

Hey folks I'm wondering about my phone, it's brand new but i read around that there some troubles with the red light of death, so i need to known what's the better strategy for my never turned on battery, could be better of i recharge it completely or could be better of i discharge it and then recharge to 100%?
Thanks

No need to discharge it. It's even better never let it drain completely.
Sent from my Nexus 4 using xda premium

Yeah, the older batteries, you wouldn't want to keep fully charged very long and you'd always want to fully drain but with the new batteries, it doesn't really matter that much. What is recommended is, as Unjustable said, you don't want to fully drain it.

Also don't have a charging routine.
Ex. You never charge your phone til it gets to 15%
You have to change it up a bit.
If your phones at 50% charge it. If its at 10% charge it. If its at 70% charge it. You don't wanna charge it at the same percentage all the time.

Why is that?
I always used to charge my phone when it reached below 10% and battery stats were perfect. Just recently I started charging WHENEVER I felt like.. be it at 30%.....50% or even 90%. And now since 3 days my phone automatically reaches to 100% charge from..lets say..85% etc. Even after restart it shows 100%.
Moreover, when I unplug and use it for a min, it drops a few percentage and suddenly gets back to 100% and then starts draining.
Dont know whats wrong.

That you don't have any issues is because of the battery is protected by circuitry that prevents over-charge and deep-discharge.
As i stated before it's better to not fully discharge.
Also Google didn't recommend fully drain it when u get it..

The battery in a nexus 7 flo is a Lithium ion battery (as one would expect). This particular kind of battery lasts longer if you top it off all the time (Meaning you should charge it whenever you can).

I did some reading on battery university some time ago and concluded the best way to save battery health is to keep it as much as possible between 40 and 80%, as well as try to not leave it full or completely discharge.
I've been using this method on my phone for more than a year and the battery hasn't noticeably lost capacity.

I charge it whenever possible, Battery nowadays trickle charge so always plugged in does not damage battery longevity. Install Gsam battery monitor and you will see even during charging the battery doesn't get much hotter than 30C and Lithium batteries is fine at temps below 45C.

+1 for me. When I pick it up to use it, I like it a 100% charge. I don't always know when I first disconnect it, if I am going to use it for 5 minutes or 5 hours. If I waited until it called for a charge and picked it up with, say, 25% power, I would be screwed if I wanted to use it for a long period of time. I wish they came with swappable batteries like a phone, so I could get a couple of spares, keep them optimally charged and then switch when the one in the N7 got low. Alas.

I charge mine while I sleep. Haven't ran it dead yet.

Best solution is a portable power pack, it just adds some extra bulk. Someone will eventually release a battery pack case to take advantage of the wireless charging.
Is it still the case that the earlier you recharge, the longer your battery will survive? I haven't run my Nexus 7 into the red so far, which is pretty easy to avoid when it lasts for longer on one charge than I could ever imagine using it non-stop.

There was an article on Gizmodo that recommends not to let it go below about 40%. I would post a link, but XDA's not letting me.

This. You guys that are allowing it to reach the point where it tells you to change are causing premature wear on your batteries, especially if you allow it to reach the point of turning itself off. Nothing is going to immediately fail, you're just going to start wearing out your battery faster. We'll all eventually reach that point of reduced capacity or inability to accept a charge.

I try charge my devices before they hit 50%. Doing so will about double the longevity of you batteries. Of course their are times when this is not possible, but with a car charger and several QI wireless chargers it not a problem most of the time.

Do you only let it charge to 80%, or do you let it charge to 100%?

Only up until 80%. If you have to charge close to 100%, at least try not to leave it in that state for long, since that's what damages the battery. Also, try not to discharge below 10%.
Of course, these are all just guidelines. You battery will degrade anyway, it's just a matter of time. There will be minimal impact if you do a full charge-discharge cycle from time to time, but the less often you do it, the better for your battery :good:

Right way to charge our Nexus 4

Hello guys. I've read some articles regarding Li-Ion batteries, how to take care of them. Though our device have a Li-po. (Dont know whats the diff.) I apply my Li-ion charging to our device.
I got the attitude to top it off whenever I got a chance.
I usually charge my phone 30-50% left on my battery.
I really dont try fully charge my battery. I plug it off charge whenever I wanted to. Cause partial charge is always better than to be full charge all the time.
All this was base on Li-ion, how to take care them.
What the others how do you?
Thanks!

I charge it always from 1% (or empty) to 100%
(Maybee two exceptions in 10 months.
It should be calibrated that way all the time according to what i see in threads. But I really dont know is it wise or not.

This is not a good idea. You should avoid completely discharging li-ion/po batteries, rather doing partial discharges.

android itself wont allow fully discharge.the 0% android means still have some juice. but because doing a fully discharge on a lithium based battery is not good, google implemented that auto shutdown.even the bootloader haves a check so you cant turn on it if you have really low bat.

I'm not too worried about whether I charge this way or that say but I do know a while back I watched a video explaining about these batteries. The batteries that we have are "smart" in a way by for example when it reaches 100% it doesn't keep charging it'll drop down to 99/98 and then charge back up again
