How long does it take for the battery to calibrate? - Nexus 4 Q&A, Help & Troubleshooting

I think that's what you call it, anyway. I've had my phone since Wednesday and am getting about 3 hours of screen time/12 hours of battery life total (it gets me through a school day). Most people are saying that it tops out around 4 and half hours, which I have yet to see. So how long did it take your Nexus 4 to finally reach the maximum battery strength? Thanks!

After two weeks of usage, I'm getting an average of 3 hours of screen time out of total 24 hours of battery life .

Lithium batteries can't be calibrated. They work 100% from the first charge.
What may not work correctly is the battery full indicator, so for example it might say 20% left then suddenly shut down without warning, or show 1% left but still keep going for ages. You can calibrate this indicator by charging to full and letting it run until the phone shuts down for a flat battery, it only takes one cycle like this for it to be correct.

Extended battery pack?

Yeah so I burn through my battery in 6 hours... people say that it can last 24 with heavy usage. But that's total BS. So is there an extended battery pack that I could get?

If you burn through your battery in 6 hours youre doing something wrong. Try.draining your battery all the way and then charge it over night

You should consider rooting it and running GreyBlur. I was running through the battery like crazy, actually got AT&T to swap for another Atrix and still had the same problems. GreyBlur really improved my battery life and I'm able to get through a day of medium usage and still have about ~40% when I plug it in at night.
So if im going through the battery fast that means it could be a problem with the battery?

I have a celltronix universal portable power pack. (4000mAh)
Has two USB ports to charge stuff, comes with multi tips to charge stuff, but I just use the usb cord that came with my atrix. Outputs 5v, charges in about 4 hours.
I don't use it much on my atrix, but I have before, just plug it into the usb port and recharges my phone, can get almost 2 full recharges out of it for the atrix.
I like it cause I can also use it to charge other items also! Used it for my iphone 3gs before I got the atrix.
You can charge power pack from wall, car, or comp usb.(mini-usb plugin to charge it.
Just google "celltronix universal portable power pack" it will pop up on a number of sites. ( I bought mine in a truck stop)
You burn through it because you have a defective product.

Yea, burning through it in 6 hours means you definitely have a bad battery. GreyBlur destroyed my battery life though, not exactly sure why it increased some peoples' but decreased others.
I had greyblur loaded once then went into recovery wiped everything then installed again first time battery barely made it to 4-5 pm when I went to for at 8 now 13+ hrs unplugged at 9am made it till 12:30am id say that's awesome. U probably got bad battery get couple new ones from what I hear they r cheap. Every phone is different t as far as battery and speed like my battery is awesome but when I run the graphic test I get 2300-2500 scores when I see others getting 2600-2800+

Ok. So i'll go to the AT&T Store and what should I say so that theyll give me a new one? They are hardass's and I need to convince them, any help on that part?
Don't lie. Tell them you think the battery life has been unsatisfactory. And with a battery that big you should be able to get better than 6 hours.
I burn through my battery pretty quick too though. Today it was dead around 6 hours (11-5) charged and now near death again. But I don't have a screen timeout, notifications on, downloading podcasts on listen(listening to them on speaker), everything on 3G. I don't care what phone you have, that's killing the battery. Its hard to make a battery last on a lazy Sunday.

YABB Yet Another Battery *****ing Thread

Gawdang battery, lasted too long!
So my first android was the nexus one, then the galaxy s, then the nexus S. I am used to the "fantastic" battery life of android phones. So yesterday I was deciding on whether to get the galaxy nexus to continue the tradition, but decided to get the note instead.
I want to do the right thing and that is to do a full charge and full discharge on the first few rounds of battery life but it took AGES for it to discharge fully. I am so pleased with this, I now have better battery life than my wife's iphone.
******** If you see the battery chart, I could not resist playing with the phone so did a little charge there. I am also trying to avoid root as long as possible, after the so call "stock vanilla" experience, its nice to have toggles on the notification without jumping through loops
Wow. 6 hours. That's impressive

That's good to hear, getting my Note in 2 days and I can't wait. Been trolling the forums and hearing a lot of good things
I got my Note on Thursday morning. I didn't have time to set it up until Friday evening. I fully charged the battery first. I've got gmail and twitter syncing, and bluetooth and wifi on. I've made a few calls and showed it off to my family on Christmas Eve. It hasn't been heavy use by any stretch, but I have yet to recharge the battery - it's at 33% right now with screen on time of just over three hours. I'm pretty satisfied so far.

You see from the screenshot that he was charging for a while.
So I don't understand this thread. How can you know how long battery last for if you part charge it?
Not much to understand, my friend. This thread was not made to prove anything, just to show I am real happy with my phone. You are completely right, I did charge it in the middle, I was transfering songs and movies out from the computer and forgot to take it off the usb.
I am now on the second from full to zero. Lets see how much screen time I can get, but already its a winner for me. 77% with 10h on battery and 1h 39m screen time.
Happy holidays all.

Congrats on your new purchases, may you have much joy with it, like I do mine.
i got the note a few days ago and im very pleased with the battery usage. right now on normal usage im on 48 hours of on time, with 40% battery left. display is the biggest usage of course, and has been on 2.5 hours. ive done lots of installing via wifi and playing with new apps and running games, and a few calls, etc. my old galaxy s would get 48 hours only with very minimal usage and nowhere near 2.5 hours of the display on.
So I am now on my 2nd discharge or 3rd and I rooted it, so there was a whole lot of plugging in and adb and stuff, but I think on a real discharge I can get away with about 4 hours screen time, that is stretching it i think but, generally still very very happy with it. Compared to the nexus S and the galaxy s before, this is heaven for me. I still maintain its better than the wife's 4S
Wow. It sounds like a lot of us with battery problems might still have half full batteries falsely claiming to be empty. Aside from turning off the heater function, this might be the next big explaination of "poor battery"

To all those with lousy battery times!

I have a year old Note and have been getting progressively lower battery times, I have tried every possible trick and several ROMS. Recently was getting as low as 12hrs. I have had a cheap replacement battery (non Samsung) which was not used often. Recently when I used it I noticed about the same battery life as the original. I purchased a new Samsung battery and now I am getting over 40hrs on one charge with moderate use and sync on with no other changes.
My messge is : change your battery at least every 8-10 months, you will be astonished as I was. One of the great features of the Note is the ease of change of battery, use it!
Yep same for new battery and it's like I have a new phone. Without changing anything my screen on time almost double.
Envoyé depuis mon GT-N7000
I've been doing that for over a decade now but this time i bight a hyperion aftermarket.
I bought two actually. I keep one in my car. This way I'm guaranteed a full day's worth of heavy usage.
Also got the dock + second battery charger.
I'll never get a mobile without the ability to replace the battery.
Screw the new HTC devices.

Non removable battery is a deal breaker - your phone will be useless after 12-24 months depending on the charge cycle.
Gotta visit HTC forums...

after 12month I replaced my Samsung battery with a Anker 2700mha and my battery life doubles.

i don't have the time to order a new battery online or look for it in stores so simply i swap out the kernel for the rom i'm using and with the current one i get about 20hrs which isn't much compared to when i got it a couple months ago and worse yet if you have on hsdpa+ whole day battery life drops to about 2/3
After one year (for me ten months) the note 1 needs a new battery. Decreasing bat life, random restarts, and screen flickering are all indicators. I thought i had runaway process issue or hardware problem. But i finally ordered an ankor battery from Amazon and my unit is fine andback to 20hrs.
I thought this was settled back in Nov.
Now just waiting for my jb!

Do not buy a spare the time time as the phone if you are not going to use it until the original goes as it will deteriorate from the day it's made, even with out use.
From box 13......
I don't know if this is still necessary nowadays, but I always use the battery till it's about to turn off the phone. My batteries always have a pretty good lifetime, so I imagine that helps.

This is a common misconception that if you leave the battery to almost deplete every time it will be better for it in he long run. I have done a lot of research on this topic for laptops and smartphones. Essentially they use the same type of battery technology which does not suffer from memory effect, but if you stress the battery a lot (letting it deplete before you charge it again or almost deplete below 5%) than it will damage it more quickly.
The optimal way of charging your battery is:
1) After the first cycles just charge it whenever you want (even it is at 70% and you are at work, you can plug it to get another 10% and then unplug and use)
2) Don't let it deplete, it will stress the battery too much and damage it in the long run
3) Every 30 cycles, you can let it discharge to below 5% and let it recharge until 100%
I have done this on my PC which still has its battery at above 80% after almost 3 years, and to some extent on my Note, but as I can't always foresee how things will play out I sometimes need to use to until the last drop of energy .
Hope this info helps.

That is definitely battery drain. Better post a screen of the battery your apps are using...
With a brand new battery, you cannot achieve much more than 5 hours of screen on time with general usage.
You can indeed get much more than that when watching video, but that is the only scenario where that is possible (or maybe staring at a black picture for hours).
So people saying that they get 10 to 12 hours of screen on time are really getting 10 to 12 hours of uptime, meaning the phone is turned on but is sleeping most of the time, with maybe 2 to 3 hours of screen on time.
That's lousy battery life, and those people should buy a new battery.

did anyone "calibrated" their nexus?

I'm moderately using the nexus and only getting 5ish hours of screen time with brightness halfway. And people been saying that they get 7+ hours.
If you happen to be one of those people, did you calibrated yours? And how do you do it? I heard you have to drain the battery and then charge it back up. Does it work? Or is it just a myth?
They are many variables involved here beyond screen brightness. You are not going to hard core game for 7 hours out do anything that has CPU/GPU running high.
I keep my brightness set to auto.. Half way seems way to bright to get any decent battery life.

About 6 hours of use. If I let it sit I get a day of standby.
Games, Internet, and netflix kill the life for me.
Last week I took it to work and forgot my plug. I watched Netflix on the battery for about 4 and a half hours. It was at 8% when I left.
Avg of 6 seems the norm. /shrug
That seems about right actually at 50% brightness. I keep mine on auto but it is usually at about 10-15% brightness and I can get 6 hours all day long over a bay or two of the charger

From initial setup (battery came at 62%) I let it completely die and then proceeded to do an initial battery charge cycle (charged it for 6 hours). After which I put it on the charger at about 14% which is normally right as I go to bed for regular charge cycles.
As for my battery life, I get an average 8 hours screen time while doing heavy gaming, watching Netflix/Youtube, listening to music, reading, and lastly browsing the web. As for standby time 3 days on battery on average (with Wi-Fi off during Sleep and always scan for Wi-Fi off).
This is with auto-brightness as I've found zero need to adjust it save for a few occasions I had to raise it for a few minutes while outdoors. If you want great battery life, leave the Nexus to it's own devices It knows how to handle it's brightness; very well I might add.
Granted your mileage my vary drastically as my Nexus 7 was flawless when purchased with zero of the known issues. (It also brought me to this lovely forum. )
Realistically you only need like 10-25 percent brightness on this thing at most times. This thing goes really bright.

auto brightness
About 10Hours of battery life.
Get about ten hours of battery life. I have brightness set to half. The real part that was saving me battery is the advanced wifi settings. I set it so that it never searches or keeps wifi on when sleeping. Also manually turn off wifi when I don't have coverage. I use alot of YouTube, internet and Netflix.

How many times per day do you charge the G2 from empty to full ?

I do it about 1.5 - 2 times per day.
A friend of mine do it about 3 times per day (he likes to play lots of games, even though he's an old guy, go figure...). I had a discussion with him about this, I told him that lithium batteries die after about 400 charges (from empty to full) which means he will kill the battery in about 3-4 months. He told me that polymer batteries like in the G2 last longer. Is this true ? this will be kind of sad to have a phone with a dead battery you can't replace...

What he said. I usually put mine on charge when I go to bed, whether it needs it or not. It was at 60% last night with 4 hours of screen time. I don't play games other than solitaire and don't facebook it or anything. Emails, phone calls and play around with it like heck.
It's probably best to charge more often, before you dip below 50% if possible.

Every 2 days i charge my phone once Erica
"day" = 24 hours?
"empty" = 1% charge (forced shutdown)?
"full" = 100% charge?
Using that criteria, my answer is currently .043 times per day.

Yes I charge my phone once a night on wireless charger. At 69% 12 hours into it. I use it to browse XDA and check email. Granted I worked most of the day vs screen time.
