[Q] first charge? - Nexus 4 Q&A, Help & Troubleshooting

do i drain the battery before first charge? is it really necessary to do overnight first charge or 3-4 hour full charge will do? need to take extra care since it is non removable.

I know that's really un-educated but I'm not sure about those things as well ... is it good to drain it first and then recharge it, or recharge it at the beginning .. and is it bad when you take it off the charger in the middle of the process?
I know it depends on battery type. And actually what would make sense is just following the manual. Why shouldn't the manufacturer know?
Anyway, anyone with some knowledge on that, please help!

Nearly all cell phones use Lithium-based batteries, which should not be drained before charging. The "drain before charge" thing only applies to nickel cadmium batteries.
You should charge your phone battery as often as possible. It's better for the battery to go from 100% to 80% five times than to go from 100% to 0% once.

I have read several articles that state it is BAD to completely drain a lithium polymer battery so I plan to just keep it charged as usual.

I've heard the same info too where it'll damage the battery by draining it completely. Although, I heard that power management on devices sometimes need to be calibrated by taking the lithium battery to near 0%...it's that way on my macbook pro...not sure about phones.

Charging Battery

I was reading through the manual for the 8125 and it said to do a few compleate charged-empty cycles. I have read other places that with LiIon bateries you do not want to let them go below 40% for long.
What do you reccomend for the best long term battery life?
Do a couple cycles, then keep it as full as possiable?
Thanks
Normally the best thing to do when charging a new battery pack for the first time is to charge it fully and let it discharge fully for the first cycle. After that, Li-on batteries tend to perform best if the charging cycle is alternated between charging after a full discharge and a recharge when the discharge hasn't been completed. However, I'm not an expert on this so you might want to get more info on this but basically Li-on batteries are less likely to suffer from the lazy battery effect or memory effect that Ni-Cad/Ni-MH batteries suffer from.
Be careful.
I have seen some posts elsewhere on the forum that report problems if you let the battery run down completely.
Apparently if you do it won't recharge on the cradle again and you have to take it off the phone and use a special modified lead to recharge it.
Best to keep it from draining to zero.
That is what I have read about Li-ions. My wife thought you were susposed to drain it down all the way, and now her laptop battery only lasts 20 min. I don't want to end up like that.
I don't want to end up like this

PROPER way to charge your X1's battery?

before everybody tells me the search function, I already have but I find mixed and contradiction answers on this issue. Some people say to do a full discharge followed by a full recharge as soon as you get the phone. Then on the other hand some people say that you shouldn't do this since the x1 uses a li-ion and its bad for it. Some people say you should charge it only when it's near empty, but on the other hand some people say to keep charging it as often as possible. Some say to take it off the charger once its fully charged, but then some say its ok to leave a fully charged battery on the charger.
As you can see, from searching the forum I've gotten pretty confused. so what is the PROPER way to charge our x1 battery? Is it also true that battery life gets better the more you put it on the charger? Does the x1i get better battery life than the x1a? I'm asking this because I'm gettin very poor battery life on my x1 compared to the 1-3 days of heavy usage that I see other people gettin on this forum. I'm going to exchange it today for a new one, so I don't want to make the same mistakes with charging my battery as I did with the first one.
Charging:
Do charge the battery often.
The battery lasts longer with partial rather than full discharges.
Discharging:
Avoid full cycle because of wear.
80% depth-of-discharge recommended.
Re- charge more often. Avoid full discharge.
Low voltage may cut off safety circuit.

that is very true......i get better life (3days) when i charge from 50%. otherwise i barely get more than 24hr.
thanks, that helps a lot! but what do I do once the battery has finished fully charging on the charger? should I take it off or is it fine to still leave it on the charger?
i have noticed this today,
i have installed a battery indicator bar (i cant remember which one) i charged my my X1 during night, when i woke up, i found that the phone is not charging and the battery is full. so i think that the phone automatically stopps charging when the battery reaches 100%
anyone can confirm that?
Not sure about the way to charge it, but i can comment on your current battery life. when i got mine, i had 1 days battery life, but after flashing it, i'm now getting between 3-4 days......

Glad to see that there are people that read the "real" stuff (I'm talking about dogans), the batteryuniversity site is mantained by the very battery fabricants, so their opinions are the best informed ones, even if they might bias a little to keep the bussiness "healthy".
However, any Lithium battery should not be fully discharged -at least not often-, because the full discharge shortens their life.
Usually, good chargers do control the charging parameters (battery's voltage, current and temperature curves) while it charges and "know" when to stop, even if they really don't stop ever (normally), the go in "tickle" charging mode, to keep the battery "fully" charged.
Hope this helps.
The article on Wikipedia about Li-Ion batteries is quite informative as well:

It specifies the technology, the do's, the dont's and usefull tips in keeping your battery in good condition.

Cradle use and battery health

At the office I leave my phone in a cradle. When I get calls I remove the phone to answer and then return it to the cradle when done. My battery goes from 100% down to somewhere in the 90's then charges back to 100% in the cradle. Does this repeated process harm the battery in any way? I've read that these batteries don't suffer from the memory effect, but I'm still not sure if this counts as a charging cycle.

You should always let the battery run down completely some times maybe once a week.
Really? I've read on this forum that there is no need to do that with the new Lithium Ion batteries. I've even read that this could have a negative effect and you should try not to let the battery drain completly.
I don't understand why there isn't a proper battery care section in the manual. Its as if its some kind of voodoo science.
Perhaps not Once a week. But Once a "while"
The reason is that, Phone software uses approximation to calculate the charge left in the Battery. So over time, battery ages and software may not be calibrated to match with the battery's storage capacity. So draining the battery entirely and charging them fully gives the phone's software to assess the battery's health and recalibrate.
It's a lithium battery mate. The only way you can really damage it is by a complete discharge. So long as you don't switch the phone back on once it switches itself off due to low battery you needn't worry about anything else.
Also in theory the lithium batteries have a lifespan of say about a 1000 charges for example and everytime you charge it has one charging less left. This ofcourse isn't exactly how it is in practice but charging the battery alot wears it down. It isn't good either to keep it in the charger for a longer time after it's reached a 100%.
Hi,
this is only partly correct:
Suppose the battery can make 1000 (which I don't believe) charge cycles,
it means that you can charge 1000 times from empty to full.
If you just charge 1000 times from 50% empty to full it counts for 500 cycles!
So,
don't worry, let it stay in the cradle if you like
There are 500 opinions about that but believe, as I wrote is correct.
Theo
Yes, what I said wasn't exact science and I used 1000 cycles as an example, but from what I've read it is better to let the battery drain to less than 50% and then charge it full rather than charge 5% at a time. My previous post was meant to illustrate this.

That's a load of crap, no offense... Lithium batteries have no memory effect and have absolutely no need to be completely discharged, that's a ancient thing from the time of nickel-metal hybrid batteries. The only actual reason for full charge cycles is to calibrate the device for that exact battery.
Keeping a lithium-ion battery in a charger most of the time will wear the battery down faster than getting it drain more and then charging it. Keeping the battery almost fully loaded/in a constant loading state wears the battery capacity by approximately 20% a year (can't recall the source/study just now)(EDIT: and my personal experience is that the battery capacity will wear that much anyway, no matter how you use it). The life-cycle of phones these days are roughly two years nowadays so IMO you can keep it in a cradle with no worries, if you wish. And lets face it, a new battery after a year of usage won't be that big an investment after all.
To add to the above post, running down a lithium battery completely does more damage than benefit. This is almost impossible though with normal use as the phone shuts down long before the battery is completely empty

How to correctly charge lithium polymer battery

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.

New battery, how to "initialize" it?

Hi everyone, i've ordered a new battery (Polarcell 2900mah) and i should receive it this week...i saw somewhere that android does not really read the battery percentage, but instead estimate it. I also read about battery recalibration or initialization which is fundamental for android to proper estimate the actual power contained in the battery, but i'm a little bit confused anyway...since i want my new battery to work proper and last as long as it could, do someone among you know about this fact? Is there any guide? I can't find anything.
P.S. i have a I9505 (jfltexx) and i'm actually on RR v5.6.3...so android 6.0.1
That is complete BS.
I never "calibrated" mine.
PS: most calibration apps do the same thing, and that is to delete a file that has no connection with the battery percentage. This was stated by a Google engineer.
Batteries should come charged at 50%
That's the perfect storage charge.
If there was any calibration method, then it would be: let it discharge completely, then recharge it to 100%.
Another note, valid for Li-on batteries: The deeper the discharge the shorter its life will be. In other words, if you let it discharge as low as 20%, or lower, every day, the battery life (before it needs replacing again) will be shorter.
Another thing: Leaving the battery at 100% charge for extended periods can also damage its ability to hold a charge for a longer time.

I'm not talking about fabulous apps which do magic things...i mean, as i read, there should be some cycles of charge and discharge which nave to be done, not for the battery, but for android, in order to really manage the power in the battery, without those 20% from 100% to 80% dropping like stones. Sorry for my bad english, i hope i explained myself.

No it's complete crap. Android does that perfectly fine. There is really nothing you need to do.
That only applied to phones 4 years ago. You never need to calibrate it anymore.

As I said, I never calibrated mine and it works.
That whole "Let it discharge completely and then charge it over night" is just a left-over from the old batteries. Those new kind of batteries don't need that.
Those batteries aren't ment to stay at full charge all the time. That is the reason for the fast drop. Mine drops for 100% to 99% in the first 5 minutes. And it drops like that until it stabilizes at around 94%.
The moment your battery needs calibration is when the phone shows 30% left and it suddenly turns off. That means it shows a wrong percentage, or that the battery needs to be replaced.
OK, then i'll just swap that battery and use the phone normally...thank you all
lithium batteries don't want to be left fully charged or fully discharged for too long. it damages the poles if that's the right way to say it. so outside of that just follow what your new battery makers recommendations
