For those who have bad battery life first charge your phone fully while on then turn phone off...plug the phone back into charger while it's off it will be a red light charge until green sometimes it takes another 20 mins .When done turn phone on and plug charger in again it will drop to 99% when 100 plug out now u have a fully calibrated battery..I am on the new firmware btw

Actually it's not b.s I noticed that around 80% my phone would drop down quickly to 70% and 30% would drop 3% instead of 1 so I did this method knowing that my battery was not fully charged.since I have done this no more quick drops...instead of saying b.s why not try it first then come to a conclusion smh

I can vouch for this ...I am only trying to help those who gave bad battery drain...we do flash a lot on xda sometimes **** happens
HTC ONE rooted,S-Off,SuperCid
Instead of clowing u guys should try it..listen phone says fully charged for some but in reality it is not it will rapidly drop for example 90% but drops to 79% rapidly or drops 3% for no reason while screen is on is due to battery not fully calibrated/charged ..This happens from flashing roms sometimes this happens if you have battery issues try this method ..
HTC ONE rooted,S-Off,SuperCid
I used this method a couple of years ago on my DHD. It made a huge difference! i forgot all about this. I'll do it again later.
Thanks, I had a feeling the calibration was a little off since the phone shuts down at around 5%, let's see what happens.
Yeah, I do this on my galaxy note and sometinmes on my new one.
When 100,% through normal charging turn phone off and begin charge again. It will charge just that bit further.
One thing the note does better is thaat when off and charging you get a battery indicator on screen, not so with the one.

I'm pretty sure the only way to get a full battery charge is to hold the phone upside down in your right hand, put your left hand on the back, and spin in 3 circles, counter clockwise. You must then quickly plug the charger (within 1 second), and spin the phone around the cable 3 times, in a clockwise direction this time. Only then can you ever hope to have a fully charged battery.
I can vouch for this. :good:

Man that's total bull...... only 2 circles required
To be real for a minute if I may..... if you monitor the current draw by the phone when charging you will see that when the green led lights the phone is still pulling 60-70mA from the charger so it's still charging and can take a while longer for that draw to fall to 0mA. At this point it's fully charged.
Charging it as the OP suggests does actually allow this extra top up.
I actually think this does help with proper calibration a bit. Not sure why people are acting like children here.

The topic of batteries makes people go crazy for some reason. I will toss in my own 2 cents, the thread title talks about improving battery "life". In this case we seem to be talking about "battery life per charge cycle" and people should just be aware seeking improvement in this area usually comes at the expense of a different kind of battery life, ie "battery life per phone".
I personally am one of those who is a little irritated by the non-replaceable battery on the One because I intend to keep the phone for many years. This applies to almost nobody else I realize, but for me this thread is a helpful summary of the exact steps I need to *avoid* if I want to get the longest lifetime (measured in years, not minutes) out of the battery.

actually i'm totally cool with doing this procedure every once in a while as a way to just what it says, get a few extra minutes of battery life. hell, if very precise runtime estimates are important to you and this helps calibrate that, great. i'm all for that too. i actually *have* tried something like this and my phone didnt die and i'm sure i got a little extra run time that day.
i just wouldn't do it *every* day.
one of the findings in another thread around here (something about battery "health") was the battery ages quicker at higher voltages such as those used towards the end of the charging cycle. if you are willing to constrain yourself to charging the phone to *less* than 80% capacity (ie the opposite of what this thread is about) you will double the useful life of the actual LiOn (or LiPolymer or whatever) material in the phone.
that is all. not trying to discourage anyone from *ever* doing this procedure, just explaining why i actually strive to do the opposite most of the time.
carry on.
Known fact... it is impractical to FULLY charge up a battery while is is in use (hence, being drained). Plain and simple physics at work here and I can vouch for this based on the many years I worked in the Navy charging, repairing, replacing, and rebuilding naval vessel batteries. Granted these are not huge deep cycle batteries but the charging principles are the same.
As as matter of fact, just did the method the OP was kind enough to suggest to us and it worked like a charm. Noticed a higher mv reading on my battery! Not much but I will take it. Who would have figured on that...
+Thanks to OP for bringing this up.
EDIT: For the record, I would normally reach 4310-4313mV... after this I am reaching +4335mV - Not much but I'll take it.

As fun as it is to mock, this most likely does work. HTC seem to be pretty bad at making battery algorithms, never found myself having to do this on the galaxy nexus or nexus 4. But my battery drops to 85 darn fast now and I'm pretty sure this will help. I remember this was helpful on the desire and desire HD too.

Preparing...
With the phone in the on position.
Fully charge the battery with the phone on... (until the led turns green.)
Once the led turns green, unplug the charger until the led goes off.
After the led goes off, plug the charger back in. When the led turns green , power off the phone.
now.... with the phone fully powered off...
1. Unplug the charger.
2. Wait until led goes off.
3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.
4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.
DO NOT DRAIN THE BATTERY. The goal is not to empty the battery and recharge like ni-cads (those have memory, these don't). These are lithiums, so we need to do the opposite...
And lets all sing the hokie pokie and shout
The cells were not charged evenly, so each cell holds different charges. So when you charge it, 1 cell may be 95% another 100 and 98 etc... so when you balance the cells, they function like they are suppose to.
this phone does not have a cell balancer built into it.
So charge, wait til its almost dead, charge again til full, then do the process w the phone off?

changed the instructions on top, i suck at writing.
I suppose this might explain why sometimes my phone plunges to about 90% almost immediately after taking it off the charger, but then battery decreases at a "normal" rate after that?
So were reconditioning our batteries...
I'm 99.9% sure the battery is single cell...it wouldn't make sense to have a dual cell 3.7v LiPo unless you wanted heavy discharge.
I don't see how this will make any charge other than the phone not topping the battery off...which in that case an external charger would do a much better job is so.
I tried this and my battery has been holding steady at 100% with the screen off for the last five minutes so something worked.
So is this a one time thing to re-condition the battery or will we have to do this more then once

I gave this a try and I must say that it is working. Before I did this, as soon as I would take my phone off the charger it would immediately drop to 96%. Now as david279 said, it will actually stay on 100% for awhile and have better standby time. Good find joker, I do see a difference.

can you post this over at the other android forums so ppl know?
I read about this on a professional site but cannot remember where. Here is what you do:
"To help with battery life you can do these steps EXACTLY:
1. Turn your device ON and CHARGE the device for 8 hours or more
2. UNPLUG the device and TURN the phone OFF and CHARGE for 1 hour
3. UNPLUG the device TURN ON and wait 2 minutes and then TURN OFF and CHARGE for another hour
Your battery life should double. We have tested this on our devices and other agents have seen a major difference as well"
I am still waiting for my phone but I will try this as soon as I get it. I am wondering if this trick applies only to new phones or not? If someone will like to test this please go ahead and give us some feedback. Thanks
no offence but can you tell me how you can charge the device which has been charging for 8 hours? to my knowledge, there are circuits that avoids over-charging in these kind of devices?
You got a point. Like I said, I took this off the net but cannot remember where.
Check out this article: http://blog.gsmarena.com/samsung-i9000-galaxy-s-full-battery-test-ready-–-up-with-the-best/
It's impossible to manage 84h on single charge Or it is possible when you charge phone to 100% then leave it on your desk and don't even touch it.
Im pretty sure I could get up to a week of battery if i didnt use the phone at all. Over night the battery drains 1% max.

Don't believe everything you read on the internet..
When I was working at an Apple Premium reseller, I nearly exploded with laughter every day at some of the ridiculous rumors I heard, which were obviously wrong to anyone who sold them, but plenty of major sites were reporting they were likely..
Even now, Kevin Rose (the genius who said that he had seen the iPhone and it had 2 batteries) is still saying crap (which 2 years after I left still seems wrong to me), and every site is STILL reporting it as fact.
A lot of the stuff you read on the internet is untrue. This might be a bit true because of battery calibration and such, but I honestly do question it..

Agreed. After all, if these ridiculous battery "tricks" worked at all, then the physics behind them would be built into the chargers by the manufacturers. Unless you think they are crippling the battery on purpose for no reason? Makes no sense.
Hi.
I've seen lots of advice in several different ways about charging new tech when you get it.
So I thought I'd try a poll to see what the general consensus is.
1) Charge until light is green before turning it on the first time?
2) Turn on without precharge, but then run completely flat before charging
3) It's a Li-ion battery and it makes no difference
Thanks

Many people will tell you it doesnt matter but I know from experience that it does in fact make a difference. When I got my phone (mt4g) I starte using it right away without charging it, everything seemed fine I had an issue with the screen so I exchanged it and got a new one. This one I charged first for a few hours before even turning it on and it did make a difference. my battery seemed to be holding a charge for longer. When I got another battery I read they recommend charging it fully off for at least 8 hours then when you do power it on let it run down all the way. Do that for the first 5 charges and it will help your battery health in the long run.
Another example is my friend got two of the same phone one for him and one for his gf. He started using his as soon as he got out of the store, hers he charged for her because he didnt see her that night. He said the phones are pretty much set up identically, same software, same services running etc.. and he said her battery lasts noticeably longer than his

Thanks for the input. Ya, I have heard a lot of stories like yours.
And even if it doesn't always make a difference, it's only 8 hours, so it should be worth it just to make sure, but when you've been waiting since January for an android tablet and you finally get one in April, 8 hours is forever. ha ha

Oh, I suppose another related question is how much is fully charged? Apparently modern devices have a current regulator or something in them that stops it from charging past 95% or something? Not sure on specifics, but from what I've read. You can't charge it passed when the green light comes on anyway?
Anyone know more on this?

Many new batteries will charge to 90% or 95%, then display the light as "fully charged". They will continue to to charge to 100%, drain back down to 90%, and back and forth in order to not stick at full 100% (aka charging over night).
That being said I've heard a lot of talk about conditioning smartphone batteries etc. and for the most part I haven't seen a lot of evidence to prove that it is necessary. Lithium Ion batteries really don't need conditioning or anything as much as you'd think... that's really an old NiCad thing to do.
I did not charge mine when i first got it, the battery was already at 90% about and i simply used it for a day and a half and now i'm charging it for the first time. i regularly get new electronics devices and i never have better problems personally. battery tech has come up a ways in the last few years.
It's well known by now the Li-ion batteries do better with short, more frequent charges. It is not a good idea to run it down until dead. These batteries also do not have a "memory."

I have a 3500 mAh battery.
For some Farking reason, if the battery is under 50% and I get a call. It will RANDOMLY beep LOW BATTERY and turn off, in the middle of the farking call!!!
You turn it back on and it'll have 40+ % charge left!!!
AHHHHH!!!!!
After watching the 25 how to videos, I fixed almost everything that pissed me off, but this one thing drives me bonkers!!!!
I think that's the battery. Is its a yoo-bao from china (cheapie) or a good brand from a reputable source(sedio)? I have that problem with all the cheapies I bought on ebay.

it's a cheapy battery.
However, it's also a bug somewhere in some software...
If it hits 15% when u are NOT on a call, the phone doesn't shut off. It's only when you're actually talking that it does it.
I'm surprised to hear STOCK people saying it happens to them... When I had my phone stock it didn't do this. I assumed it was a ROM issue.
I would try calibrating... I believe there's an actual app in the market to do everything for you. I'm fairly certain its free, so ill post a link, but if its not, I apologize, and well get a mod to take it out.

Yes. I've calibrated my battery. I have seen a couple threads on the issue. I have repeated the issue on several roms and modems. Happens every time i'm on a call and the battery gets to 15%. That makes it serious since it is a phone after all. What if I was talking to 911?

What I'm hoping for is I can figure out what you guys are running that doesn't crash on you when the low battery beep happens.
I think this is a battery issue. I never had this problem with stock battery and it happened twice on cheap 3000 ma battery I bought. Returned the battery and got another one (same kind) and this one works fine. I think this is a manufacturing problem with cheap batteries. When you look at reviews of more expensive ones online, you never see anything about this problem.
I have found the solution! It turns out that our phones, much like a simple light bulb, just don't function when they don't have enough juice...
Since I can't modify a light bulb to magically require less power, the only solution I have found is to provide the specified power level. I have applied this same method to my phone - when the battery gets close to that magic threshold, all I do is - get ready for this - charge the phone again!
Seriously, though - everything takes power to operate, and a low battery can't put out the same current and voltage as a fully- or even half-charged battery. This isn't a bug, it's just a fact of life (with current technology, anyway). Who here complains when their almost-dead AA batteries can't power an Xbox 360 controller? Most of us just replace them with fresh ones (or charge them) and keep going.

This! Cheap batteries are never worth the money. I bought some cheap chinese rechargeable packs for my 360 controllers... they ALWAYS show low charge even if I just charged to full. Same deal with cheap chinese cell phone batteries.
I am sure the battery calibration is way off with one of the cheapies.

Ok Mr. Smarty pants. You are not understanding the problem. It happens with the stock battery too.
The SECOND you hit 15% while on the phone and get the battery low warning, the phone turns off, MID CALL. You turn the phone back on and it will last hours, even on the stock battery.
If it hits 15% without being on a call, it does not shut down.
That is the real problem here.
This has happened to me once , what could be the cause ? Defective phone or software?

Ok Mr. Smarty pants. You are not understanding the problem. It happens with the stock battery too.
The SECOND you hit 15% while on the phone and get the battery low warning, the phone turns off, MID CALL.
If it hits 15% without being on a call, it does not shut down.
That is the real problem here.

You mean just like a 360 controller can have enough juice to turn on, but not enough to actually play? Or how a flashlight will be too dim to be worth it when the batteries get low?
Would it be better if the battery ran like a champ right up to the second that it shuts off without warning? That would fix your problem - no notification when the battery is low (the sudden shut off can't be avoided until we find an unlimited energy source small enough to fit in our phones)
Your expectations are unrealistic. Just sayin'...

J3ff, it's likely the cheap battery. Here's why:
Charge level is a simple linear voltage function. Our phones consider 4.2V to be full charge (100%), and empty to be around 3.6V (0%). The voltage drops roughly linearly between these two values as charge is consumed.
The kicker is this: The voltage seen at the battery terminals is also affected by the interaction between the internal resistance of the battery and the instantaneous load, or current draw. For electronics buffs, this is the classic V=IR, and what happens is that the voltage on the battery will drop by IR in addition to it's unloaded voltage level due to whatever the stored charge state is.
Good quality batteries have a very low internal resistance, and will not drop much voltage due to an increased load. Crappy batteries are just the opposite, and even though they do carry the charge storage (most of the time) advertised, they are only suitable for low load applications.
What's happening is you have a battery with a horribly high internal R. When you make a phone call, the load increases A LOT -- transmit power goes way up. This if why phones get hot when talking on them -- they really suck the juice.
As a consequence, because of the high resistance, voltage from the battery takes a nosedive. At an "idle" reading of 50% (3.9V, thereabouts) you're probably dropping more than 0.3V when the load goes up during a call, the phone panics, and shuts down to protect the battery (LiIon doesn't like to be discharged below 3.3V, and can be damaged).
When you reboot, the high load is gone, so the voltage shows higher again, reflecting the fact that there is truly still plenty of charge stored and available. The battery simply can't handle gulps, but only slow sipping.
High internal R is one of the most common reject reasons from mfgs, and those batts are sold on the cheap to dealers and distributors in a secondary market. Honest ones then resell into appropriate application spaces where low-current is all that is needed. Most, however, are not that scrupulous, and sell right back to the same market, leaving behind puzzled and unhappy customers.

Hi, I've bought a nexus 4 about a month ago. I works great and the battery life is good enought but i notice that sometimes I connect the charger (when the battery is 40% full for example) and a few minutes later it says it is 100%.
Ofcourse it's not and some minutes later it drops. If I reboot the phone it shows the correct percentaje, but I happens very often.
Somebody has the same issue?
I didn't try to wipe the battery stats because I didnt install a custom recovery. Is there any way to fix it without flashing it?
thanks

Most N4's have some quirky battery stat behaviour. You'll have to learn to live with it, wiping battery stats, or reflashing the stock images, or an alternative ROM, won't do anything to address this.

It's the first thing I noticed about the phone. I've only charged from 0 to 100 in a second once though when I first got the phone, aside from that just the occasional lazy updating of the actual percentage. Stressing the phone a bit tends to help it "catch up" to where it should be.
Edit: you know, it's good OCD therapy, it may help you get past your OCD if you have it.
If you don't have OCD, you certainly will now...

Yes, the same happened to me, the issue is that sometimes I lost track of when it plug it to the charger and after use it the battery drains. It is very annoying.
I will try to charge from 0 to 100 a few times to si if the stats sync with the real battery state...
Thank
I'm getting pretty consistent reading far as 0% - 100% goes (course I drained the battery down to zero twice and charged back up).
What I'm finding that seems rather weird is glitchy mV reading with battery monitor widget pro. It does decrease as the battery decreases as expected, what's unexpected is all the lil spikes upward in it's value over time, like every few mins it'll jump up like from 3995mv to 4040mv or similar jumps as if the widget can't get an accurate reading of the battery's mV level. So it look weird because the only time you would see the mV rising, is if you're charging it.
And I know someone else on this forums with a Nexus 4 that's actually showing positive mA values when he's not even plugged into a charger.
But as far as % reading goes, seems pretty accurate now, just the readings I'm getting from battery monitor widget had me concerned that the battery was bad on my less than a week old Nexus 4. My Nexus 7's history/stats look rock-stable by comparison, kind of wondering if it's an LG thing.

Well this is odd... i think it might be an issue with the -kind of- voltimeter (battery sensor? i dont know how to name it). The battery life is ok up to now but the stats are driving me crazy!

Those of us who look beyond just the % available are easily driven crazy.
But then again because I do, I was able to prove a certain brand of charger was incompatible with my Nexus tablet.

I tried to catch it in the act via adb and shell last fall pinging the voltage, fuel gauge, etc... but that was all my n00b self was good for.

I've noticed that my battery % is off also. Not as bad as jumping up to 100% or anything, but I notice that when charging, the % is 20% higher than the actual battery. It'll say fully charged, but when I reboot the phone it'll say something like 83%. That happens a lot, and not always at '100%'. If I reboot anytime during the charging process, it drops around 20%. I haven't tried to do it right after I connect it, but every time I do actually reboot it happens. Kinda weird. Not even close to a deal-breaker or anything, just a quirk that I wouldn't mind getting fixed.

My nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171
Is it a battery issue?
I have charged it completely (8 hours) many times and run it to the bottom , tried deleting battery stats etc but nothing has helped.
Shall I get the battery replaced?
tried to delete the battery stats file and wait for a while and see if any difference?

Tried that multiple times but no change, what are the possibilities? Damaged battery? Damaged battery sensors on the phone?

Well Google support definitely knows this is a big problem. After I explained the exact same issues I was having with the battery indicator being wrong they offered a in warranty replacement right away with no trouble shooting what so ever. Problem was they wanted to authorize my debit card for the full price of a phone plus shipping until they received mine back. Unfortunately I didn't have 230 bucks that I could just have tied up in authorization limbo for 2 weeks. So they transferred me to LG support because they have a return policy where they let you ship the phone back first. LG at first tried to say they only do paid repairs on Nexus 4's and that google is responsible for warranty's, but a little arguing about manufacturer warranty laws in the US and threatening to file a complaint with the FCC they agreed to replace the phone under LG warranty. Again they didn't do any troubleshooting at all. Upon explaining the problem they went right into replacement phone. This leads me to believe there is no easy fix or software problem they can update, but rather a hardware problem.

I have exactly this behavior all of a sudden the last 2 weeks.
I have worse issues....
We had the screen/digitizer replaced after my wife dropped the phone.
The phone now has some issues. It will charge, and operate ok until the battery reaches about 80%.
Then the touch will go crazy, and the phone will turn off.
Upon rebooting, the battery is suddenly at 0%.
I purchased a new battery and installed it. It charged to 100% the first time and the phone lasted for a while.
Then after that it refused to charge at all. Didn't matter how many times I did the power + volume up trick.
I put the original battery back in, and it charges, but of course dies after it reaches 80%.
Same here. Problems after screen replacement month or two ago, not sure that related. Battery went bad. After replacement with a new one (original not chinies) not stable: shows 100% charge then turn off on in 10 min, after powered on again shows 65 % and after 10 minutes plugged in 100% charged.
Driving me crazy... Fully wiped, factory reset all the same. Rooted and wiped battery stats not helped. Very frustrating if some one can suggest one else can be done...
The phone is just fine, powerfull . no reasons to replace
I also developed my battery issue about a month after replacing the screen and digitizer. I'm going to take it apart and clean the connectors and see if that helps, because I'm so annoyed I'm about to buy a new phone.
My guess is that the battery was damaged during the screen/digitizer replacing process. It happened to me recently. No biggie 24 € for a new LG original battery seems pretty cheap and the problem was solved. But why are nowdays batteries somewhat soft??
