Hi All - Does any one know of a gadget that can charge the battery independent of the XDA itself. I'd kinda like to have a second battery on charge
IT is bettery to wait unlit the phone is fully discharged or for example If I have 50% battery And I want to charge it another 30 % is there a problem.
(I want to know if after a long period of daily using this metod is bad for my battery)
Thx
With modern batteries it doesn't matter. Older batteries could be temperamental, but any advice about charging x number of times, or completely discharging is simply no longer relevant.

its even healthier to randomly charge your battery. it doesnt have to be fully charged and not fully drained. theres no memory effect on modern batteries, just charge & unplug it whenever you like
Thx for your help really apreciate
With lithium batteries top up charges are better than drain and full charge.
I just found this very interesting article, maybe you'll like it too:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Short summary:
1. "A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life."
2. "Higher charge voltages boost capacity but lower cycle life and compromise safety."
its also suggested that you let your phone go through one complete discharge from 100 - 0% at least once a month.
- also on the heat front mentioned in the OP, i take it that means its best to remove your cover when charging your phone to stop a build up of heat?
You mean taking of the case, like Otterbox?
No, I wouldn't do so because my battery never gets warmer than 26-29 degrees.
Bad would be everything above 30°.

Our electronic profs at uni (who actually know what they are talking about) told us to keep the charge between 80% and 30%. Discharging to 0% only harms the battery.
So i'd really like to know where it's suggested that you should discharge to 0% once a month.
btw: This is a quote from the link from the op:
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses."
So i'd say that discharging to 0% once a month is nonsense and only harms your battery
I read that a while ago on the iPhone support website and did that for my old 3g, I just kept the practice running when I got my DHD. I guess either Apple is wrong or its only usefull for non-removable batterirs.

That's probably why their batteries died so fast.
gotta voice in here. i've also heard that its optimal to keep your battery in the 80%-30% range. and that its only damaging to fully drain your battery.
but on the flip side, its kinda needed to do a wipe battery stats once in a while, so i can get a better reading of my battery.... was a time when i hadn't done it for ages, and i was at 1% battery while watching a movie for 30 minutes..
so, I recommend at least, to DONT drain your battery.. but if you are getting really off readings on your battery. do the wipe battery stats thing
My DHD battery seems to be getting worse and not holding its charge. as it's almost been 18 months I decided to buy a new OEM battery and I was jus wondering how should I run the 1st few cycles? And how long will it take to reach its optimum capacity? Also will I need to wipe battery stats and calibrate it?

No Calibration is a hoax, and battery stats are wiped whenever DHD is unplugged with nearly full charge (link to follow from one of the Android devs, don't have it to hand whilst mobile)

I used to worry about battery, then i purchased two of the cheap Ebay ones for like $3 they each hold about a day worth of juice. let the haters hate on the cheap batteries but it's $3! If they are of lower capacity (which must be miniscule because i can't tell) or they die early who cares. Buy a few of them and be done with it.

Why buy many batteries, when you can have 1 quality item?
Cheap batteries can also be a security risk (exploding cell phones e.g.)

how should we go about that? play heaps of games? increase brightness? or do you mean drain it slowly like over a day?

how to charge a new battery?
I still haven't received an answer to my past post. I've just got a new OEM battery and i wanted to know how should i run the first few cycles? is there a certain amount of time i should charge before i unplug it or do i just treat it as i would with a normal used battery?

Suggested initial full charging/discharging cycles are ONLY made to train your phone and NOT your battery and in most cases aren't even intended for current android phones.
Those mythical suggestions are often based on facts for non-lithium rechargable batteries.
Nowadays rechargable lithium batteries are often shipped at least half full. So what you can and should do is just use the battery and try keeping it between 30% and 80%. That's all you have to do.

So are you saying i shouldn't even charge it to 100% and what about the recommended monthly full charge to complete discharge to calibrate the battery?
Well you can charge it to 100% if you want. That will reset the battery log of your phone, so it can't hurt that much.
But charging it for an extensive amount of time will bring you no good. The charging circuit in your phone and in general the charging circuit used to charge lithium-ion batteries will stop charging once the battery is full. That way it prevents the battery from overcharging. But it also means that charging your phone for any more time than it needs to won't make it run any longer.
The monthly complete discharge is not to calibrate your battery as i've allready stated. It is used by the phone to better estimate how much power your battery can currently hold. So in a sense it's used to calibrate but not the battery itself but the battery statistics in your phone.
The phone knows how much energy the wall-charger provides and can thus determin huch much power is stored in the battery once it hits 100% (or better: reaches it's maximum voltage). If you have a charge from 1% to 100% then the phone can obviously determin the battery's capacity more accurately than if you charge it from 50% to 100%.
/edit:
And yes. If you really want to prolong your batteries life then keep it's charge between 80% and 30%.
But just see to it that the charge is above 30% and you're good.

How so? Battery stats is wiped when you unplug the nearly charged phone, so where is this historical data found?

beats me^^
My point was that the calibration is done for the accuracy of the percentage displayed and not to make your battery hold more energy, regardless of what phone/device you use.
And i'm using Battery Monitor Widget so i tend to mean that when i talk about the "historical data". Because BMW really does tell you to run larger charge cycles to increase accuracy. It however doesn't tell you that constantly running your battery down to 0% will only shorten it's lifetime.
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.

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.
