Is this normal battery life for the first day of having the nexus?

I just got my nexus today and was wondering if this was good battery life for the first days use and when it will start getting better?

Thats a drastic drop! Id say about normal as well. Did you have a lot of apps that were re downloading from the time you first activated it. After a few days to a week when your done looking at your phone every 5 secs you'll start to see battery improvement haha.

Tonight will be my 3rd time charging it. WIll it get a lot better tomorrow?

ProTip: Put the phone down every once in a while and enjoy life.

That's normal if ur 4g on

It can take 4-5 charge cycles for the battery to really get worked in.
Also, check out the juice defender plus app. Doubled my battery life.

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.

Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.

Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.

My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

If you are using your phone a laptop replacement and are surfing the web constantly, expect it to die like a laptop.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.

Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.
I wish Google fixes the high Android OS Keep awake time!

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.

Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.

60% screen time gawt damn! Did you talk to anyone that day?

Google need to run classes on how to read the battery consumption pages. 61% screen means that the screen used 61% of the total battery used, not that the screen was on 61% of the time.

[Q] horrible battery problem on ONE X

I know there are loads of threads about the HTC ONE X battery but I really could not find a proper answer to my question so im starting a new thread. So I have had my 1X since last thursday, just over a week now and the battery life has been utterly horrible. But the worst thing is that the battery life is getting drastically shorter and shorter every day. Now its unbearable I cant even use the phone. I wonder if it might be because I did not do any 'first time battery charge'?. I just booted the phone instantly instead because honestly I did not know that you had to charge the battery before booting the phone the first time. The first time I started the phone it had just over 40% of battery and I used it until the phone shut off and charged it 100% after that while it was updating to the newest software. Is this perhaps the reason why the battery life is so god damn horrible and even worse than other 1X's?. When I charge the phone 100% it drains 1% of battery or more every minute now just when browsing the menu or the web or just doing nothing but putting the screen on. The screen brightness setting is on automatic and I have tried all kinds of battery savers and now im using juice defender ultimate still the battery life is horrible. I kill and close apps all the time and have nothing running in the background when not using it and I always turn off wifi when not using and I turn off auto sync and all the other battery eating tasks and stuff. Still I cant use the phone. When its 100% charged at about 8:00 in the morning the battery is done for at around 10:30 with moderate use. I cant get more than about 3 hours of on screen time before the battery is finished so basically what should I do? Is this normal?

3 hours of on screen time isn't high but it's not abnormal either.

And if you'd have read the other threads that you said don't apply to you you'd realize that because your phone is still new battery life will improve with more charging cycles. If you expect more than 3 hours on the low-end or five on the absolute high-end of screen on time the One X isn't for you. Because of the non-replaceable battery (which shouldn't be a surprise) a lot of us have auxiliary battery chargers for getting through the day when the phone can't be topped up on AC power. Speaking for myself, the design of the phone is what attracted me to it and the non-replaceable battery is a trade-off I accepted. That might not be a trade-off everyone’s willing to accept and the One X isn't going to win any battery life awards.

Autobrightness seemed to cause my battery to drain. Turned it off and its much better (or seems that way for now)

Charging your battery when you first get it does absolutely nothing. Wiping battery stats and callibrating also do absolutely nothing.
Sent from my HTC One X using xda premium

Upload few screens of your battery usage so we can see what is causing such drain. I can tell you already now the screen is the main battery drain. A phone can barely survive 4 hours of heavy usage, especially not on automatic brightness.

Yeah ill do that, how do I take a screen shot? Powerbutton + homebutton thing doesn't seem to work for me :S. Today for example iv'e charged the phone 3 times and after the 2nd charge I used to phone for 5 hours and 25m until only a few % of the battery was left. I had juice defender ultimate up and running most of the time and screen time was at around a bit over 2 and a half hours. All I did was some web browsing and mostly menu browsing and setting browsing on the phone and some xda developer browsing with the app. No gaming whatsoever. Really horrible battery... such a pity considering how much I love the phone otherwise. Its no problem when im at home connecting it to the computer with the usb cable all the time but when im actually using the phone outdoors its frustrating as sh*t.

It doesn't really matter what you are doing, you will only get around three hours of screen on time.

Have you tried easy battery saver, started using it on my HOX over 30HRS ago browsing, video calls and still have 33% life left. If it doesn't work I suggest you return for a replacement. Could be factory defect.

Yeah, that was the first one I used, it didn't really help but juicedefender on the other hand helps me squeeze out a bit more battery life
Sent from my HTC One X using XDA

Sounds like a lemon, have it replaced asap. HOX is the only android device I had that gets me through the day w/o charging doing basic stuffs (data always on etc) like what normal people do. I've had sleepless nights last month because my 2-week old GN got pick pocketed battery life for GN in my case was horrible (5 hours).

how do you know if your battery is defective? i'm getting around the same battery life myself :/

This is why unreplaceble batteries suck. I wish I'd bought the s3 instead still though I love the HOX only if the battery was a bit better ffs. Im getting a little bit better battery today but with loads of tweaks, still some 'untweaked' hoxes get better battery lives, still though it seems like there are loads of one x's that have the same issue as I do. Does this mean all one x are different or what?

[Q] Is it bad to keep One V connected to charger

I don't want to go too much offtopic in the PACman ROM topic as my questions have no more nothing to do with ROMs, so I make a new topic, maybe too asked, but with One V, is it safe to keep it plugged to charger all night, I mean does it make any bad things like ruin battery or something, no I am not talking about overcharge, but still should it be good, or is it bad to keep the phone plugged to charger all night so it would be ready at 100% on morning. I did read that batteries dont actually charge 100%, said it charges usually about 90-95% and that is why the first 10% will drain faster as it really is 90% instead of 100%. Is this the thing what happens with One V too, so can i keep it plugged in charger? Does it make battery life worse?

leaving your One V charging overnight IS Overcharging...
So... no, it's not a good idea to leave it charging overnight...

Everybody says its not the good way to charge the mobile over entire night. Haa haa from 6 years I do keep charging my cell over entire night. It doesn't make any difference to me.
Sent from my One V using Tapatalk 2

I still am doing this and i think it it doesnt overcharge, but i am wondering does it make battery life worse as someone said so. If not, i guess i will continue my current way to charge, but i do know it doesnt overcharge. The thing i want to know is does it make battery life worse.

No,nothing gets worse

yes it does..
my friend has a galaxy note and he used tp keep it overnight for charging and his battery got swollen soo its better to not take a risk.. unless ur a rich **** and willing to shell out

I agree. It's not good to overcharge
Sent from my One V using xda app-developers app

Now, what I found was:
"HTC One V - battery charging questions
Should be fine, the batteries use Lithium cells and have pretty good built in overcharge/run down prevention. They are designed to be left on the charge overnight and collected in the morning. They will charge rapidly over the first 1-2.4 hours (assuming a 3hr charge cycle) then slow down. Eventually it will just bounce off 100/99% as it charges/discharges." - from HTC...
"This "smart charger" is built into the phone. It slows down when it gets near capacity. In fact I think even the LED light goes green to indicate it's full at around 95% if I remember rightly (I read it on XDA."
"Advanced state-of-the-art internal circuitry protects the HTC One V from power surges, overcharging, and short-circuiting, to significantly extend the internal battery lifecycle."
"Is it OK to leave my battery plugged in, even if it is fully charged?
Yes, it won't hurt it as long as the battery doesn't overheat.
Source: http://www.batteryuniversity.com/partone-14A.htm
Should I remove the battery from the charger when full?
It does not matter. The charger automatically cuts the charge current when the battery is full."
So, after all that, whom to believe?

sooo after all experience is to believe and your surrounding persons and their experiences.. I've got my friend's note's battery swollen soo i wouldn't take a risk.. after all its your choice

Honestly I've owned a galaxy vibrant, Huawei ideos, vs2, optimus v, and this one v and I've charged all over night and none have suffered battery life issues. In my opinion no not a big deal lol

why would you need to charge overnight? are u on stock? in that case you might as well leave it overnight to charge......FYI my One V takes only 90 mins to go from 10 to a 100%

[Q] One X Battery Re-Calibration

Hi XDA,
I am pretty noob at forum posting so no hate
As we all know, the One X does not have a great battery, but, it enough to get a whole day, recently my battery starting playing up, Id have 20% left, and it would just keep turning off, as if it had no battery, I full charge it, and that seem to not occur again, Id listen to music for 20 minutes and Id loose about 8% charge, Im not using headphones, just earphones, now, im loosing 15-20% battery, id also loose battery with it in sleep, firstly I tried to wipe battery stats in CWM, and I loose 2% just from that!
All of that within a week, except for the 20% turn off thing.
It also seems to be a little warm around the camera, and a bit more below the camera.
Ive tried recalibrating using Battery Recalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en)
Ive tried full charging after a full drain.
Nothing seems to be working.
Im running:
Rom - Viper 3.3.4
Kernel - The Viper Provided boot.img
Hboot - 1.36.0000
Any help is much appreciated
Ill provide what ever you want to see (screenshots etc)
Thanks

Re-calibrating battery doesn't do anything for battery life. It's a myth. Read up on that. Maybe your battery has become old, or overheated at some point and is now malfunctioning. Too much heat is bad for batteries and overheating has killed one of my Desire HD batteries too. They expand at the middle and also lose their capacity quite a bit i.e. they discharge faster.

Okay, That might be the issue, Thanks

Full Draining your battery is a bad idea..
As the One X has a Lithium Ion battery
and they dont like to be discharged very low

shuts at 36-40%

hey......friends my desire always shuts down at 40% of battery when I fully(100) charge it.....I want to know that if it is a battery problem or phone defect?

If it's still the original battery, it's very likely due to battery aging
You can try to properly calibrate the battery (NOT by wiping the battery stats), there is a proper method which is supposed to work. But this doesn't give it extra live, just tries to reset the readings so it displays correctly. It will simply appear to drain faster, but hopefully shut down closer to 0%
My advice would be to buy a new battery, make sure it is an official one or from a reputable seller with good reviews.

thanks dude.....i will try changing battery if it works
