So, I'm wondering if my battery is messed up. It seems to charge from near dead to full in roughly 90 minutes (depending on whether I'm using it or not). Is this typical?
I ask because I feel as though people talk about their phones lasting much longer than mine does, and it makes me think I may have a defective battery.
Do other people experience this short charge time?
I had an Incredible before this, with a smaller capacity battery, and with the quick charge implementation it would still take slightly longer to charge to 100%.

Thoughts? Ideas? Suggestions?
All greatly appreciated.
Thanks
How is your battery lasting during normal operation?
It doesnt matter how long it takes to charge if it behaves normal in everyday use.
Mines does the same thing it'll be nearly dead(4%) and will be charged to 100% in about 2 hours. The weird thing is that my battery life is still pretty good(averaging 12-14 hours of usage with 4-6 hours of on screen time and no wifi), just kinda strange when I first received the phone it took longer to charge.

It's completely normal to have the phone charge that fast. It is the way Li-Ion batteries work. They have a super charge state where the battery charges itself in minutes from 0% to approx. 85% and then starts to trickle charge the rest of the way. This is to ensure that the battery doesn't die from all the rapid charging.
I probably get about 2 hours of screen on with wifi, and usually im on a very good wifi connection.
it often seems im down 40-60% within 2-3 hours of light use: texts, checking the time, nothing major.
Maybe I'm expecting to much from this.
My Dinc used last a lot longer it seemed.
And yes,i generally keep 4g off

I am getting the phone for christmas and was just wondering if I have my parents charge it the night before, will it last me all day? What is battery life like on the first charge?
You'll likely burn through it pretty fast on a first charge. Best I know, it's not optimal until about 3-4 cycles.
Mine was pretty horrendous at first and then again for the following couple of cycles after that. Now on 4.0.2 and a number of cycles in and I think the battery life is stellar when you consider the screen size. Pretty similar to my GSII so cannot complain.
My advice. .. take the charger.
Regards.
I got about an hour of continuous tinkering after a 10 minute charge. Had to plug it in after that.
The first charge will be the longest lasting charge you will ever have on this battery - depending on your usage.
LiIons degrade a wee tiny little bit with every subsequent charge.
Thanks, I can't wait to get it.

While this is true, I dont think its calibrated the first time.
I got my nexus yesterday and charged it up from 50 to full and it was literally at 0% 10 hours later, today is a different story, I've been able to get about 12 hours of use out of it and have about 35% battery left

Calibration only affects the battery icon, if they use poor logic to calculate the charge. The system can read battery voltage precise to 0.001 volts and it's actually quite easy to gauge a LiIon cell: 4.200 V = full, 3.600 V = empty (without load on the battery)
My first charge only lasted about 5 hours, and that was because I was playing with the thing the whole damn time. ;-)
My first charge
This is what I got on my first full charge. Was on Wifi for most of the time. Bluetooth was on often in the beginning to transfer files.
Used GPS for like. Facebook sync was off. Gmail, Google+ on. No Reader, Google Photos, Docs sync.
I bought the extended battery and it both were about 40% charged. You'll want to burn it down completely till it powers off, then give it a full cycle.
You'll kill it just by setting it up, playing some games, playing with the OS, reading XDA Rooting guides, taking pictures etc.
Just kill it, then put it on the charger while you get a shower and dressed.
...then you'll probably kill it again by the end of the day cause you can't stop plating with it.

Ive read that the way weve always used with the wiping of battery stats actually doesnt do anything.
I got a GTmax 3500 mah battery but the phone turns off at 0, even though it has power, its sitting at the recovery screen and is just fine. I was wondering, do i just leave it here to drain it, or do I have some other method of calibration. Im pretty sure its going by its old stats because it drained in 12 hours and turned off. I SHOULD get ~23-24 hours on the new battery.
Yes, it has been determined that the battery stats file we used to wipe does absolutely nothing to prolong the battery's charge on any Android phone. The only thing it does is wipe out the statistics that we see for what is using the battery. Personally, I've never noticed any difference in battery longevity when wiping the stats file, so I stopped wiping it long before this information came to light.
As for your issue, the phone turning off at 0% seems pretty normal to me. I'm not really sure what your concern is. Just because you can access the recovery screen doesn't mean there is enough power to let the phone run normally. I would let it charge for several hours before using it again or at least leave it on the AC charger while you use it. It is also not a good idea to let the phone discharge down to 0%, as this can shorten the lifespan of the battery. Typically, the battery power meter is pretty accurate. Plus the battery should be fully charged before use. It is speculated that if you condition the battery itself (fully charge, then fully discharge (the one and only time this should be done), and fully recharge it again), you may see better life. Considering that on a typical day, I get about 5 hours of heavy use before I have to plug it in, I would welcome 12 hours without having to charge.

Thats strange. I got some friends with iPhone 4S and they get over a full day with some moderate use. I get 12-16 hours tops. I can easily drain it in 8 hours. Doesnt seem like it should require mid day charging.

It is very difficult at best to compare iDevices and Android devices. The hardware and software are completely different. Regardless, I also know folks with the iPhone 4s. About half of them drain their device within 5 hours. Constantly doing stuff... The batteries on most smartphones are just not up to standards with today's hardware. At any rate, the rest of the folks I know with the iPhone 4s are more moderate users. They get about 7-8 hours. One person claims she gets 9. It depends on usage. Plus, as avarize stated, underclock, a decent kernel, screen brightness, etc... And SetCPU is a great app (even for non-rooted devices). Also, constant text messages tend to drain devices. It just depends on how you use it.
Is there a preferred battery charging regimen for the One X battery?
That is, is it better to, say, always let it drop to 15% and then recharge to 100%, or can/should I charge whenever possible, or in smaller increments?
Also, are there disadvantages to using the phone while charging (as I tend to do quite a lot )?
Thanks!
i normally let mine down to about 10% then just charge it too 100%

Right, but do you know if this is actually the way to go with the Li-Po battery or are you, like me, just winging it?
When i first got my phone i let it run down till it asked for the charger, then left it on charge over night.
I did this for the first 3 or 4 times as i found this yields the longest battery life, since then i charge every 2 days regardless what percentage is left always over night though.
Going to leave it tonight & see if it will go till tomorrow night, its been off charge since 7am on Friday morning so far & is still on 46% a total of 39 hours so far.

You get two days on a charge? Are you a wizard? Although, having just got the phone (and possessing the patience of a 5 year old), I've done a lot of start-stop charging, which I suspect isn't optimal.
I'll try to refrain from trickle charging for a while, see how much difference it makes. Thanks.
Another battery charging thread? Just plug in the damn phone! It will take care of the rest.

I have noticed that the battery does drain in strange amounts.
I have my wifi & gps on constantly, my phone went for 2 days 5 hours & i received a text at which point the phone was at 34% battery.
The phone was put back in stand by & the phone went totally flat in the next 4 hours, this i find strange as over night in stand by it only uses 1 - 2%.
There is obviously a bug in the way the phone reports its battery state, by my reasoning this must be some 10 - 15% lower than what it is reporting.
It does seem to have some difficulties reading the battery level correctly. I've noted a couple of times that it shows a significantly higher charge level (+5-7%) after a reboot. Which is hardly likely to recharge the battery. (Unless I got me one of those perpetuum mobile, in which case, yay!)
It takes about 3-4 hours sometimes to charge from 99% to 100% but just a few minutes to drop from 100%-99%.So, my question is, is it worth to charge the battery on your Nexus to 100%? What do you guys do? Any advantages of charging the battery to 100%?
I'm talking about the stock battery in the GNex.
Thanks in advance,
vG
doesnt take that long to go from 99 to 100% here. its usually pretty quick.
percentage is really a horrible way to gauge battery charge level. Efficiency wise it really isnt worth the time invested to charge beyond 90% but either way it doesnt matter. if YOU feel it isnt worth it, dont do it.

This is stating the obvious, but only you can answer your own question.
How much is 3-4 hours of time worth to you? If 3-4 hours is worth the same as the few minutes it takes to go from 100% > 99%, then I guess you could say its worth the wait. Otherwise, no.
The technology in today's battery is so good that charging even just a little don't harm your battery like it used to do.

Most kernels (including stock?) have a cut off of 96% actually.
The remaining 4% is just placebo...
It's not great on a battery to remain at full charge so it's really dropping and raising as determined by your kernel but the phone will display "charged" no matter where in this cycle it actually is.
The couple of percentage points you're losing are so minimal it's nothing to worry about...and it's innacurate.
I think it comes down to what you mean by "is it worth it?" If you know that you're going to be away from a charger for a while and need every last bit of power you can get, then yes. But if you can get through the day without recharging or have access to a charger to tide you over then I would say no.
My goal is to be as gentle on the battery as possible so long as it does what I need it to do. Personally I try not to charge my phone above 90% and try to recharge it before it drops below around 30%. (this is based on general lithium ion charging recommendations from here:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
I am able to get through the day with this setup and I have access to a charger at work if I ever run out of power. If you're charging your phone up to 100% then recharging at home with 50% remaining, you may consider stopping charging at 90% so that you have 40% at the end of the day, as it will be easier on your battery.
Thank you all for the valuable advise. I am using Rasbean Jelly ROM with Trinity Kernel so I get pretty good battery life so, I guess based on the feedback, I am going to skip charging to 100%. What I kept wondering is if there were any drawbacks to not charging to 100% but doesn't look like it.

Hi, My battery used to stay at 100% for at least 20 min with minor use after taking it off the charger. Now, it drops fairly quickly to 97% with the same usage. Overall I think I am left with the same percentage at the end of the day, but I was wondering if anyone else experienced this.
How old is the battery, are you leaving it on the charger for long periods after it's fully charged. Their longevity wears down so it's going to happen. But you can take some steps to stretch it out to the max. Mine goes from 100% to 95-96% in about 30-45 minutes right now

Thanks, Its about a month old. It is on the charger for at least several hours after its fully charged. Also, I am completely stock.
Just curious, is your device idle in the 30 min that it takes it to go from 100% to 95%? If not are you doing intensive stuff to takes it to 95%?

Yeah mostly idle, just running back ground tasks and such. Very minimal use.
Also I think leaving it on the charger for long periods of time reduces the life span of the battery as well. That's why it notifies you to take it off when it's fully charged. And I believe I read that somewhere else also.
But also if you leave it charging all night the phone may say 100% however the phone to prevent it self from charging the battery to long it stops charging it and let's it drain from 90% to 100% and slowly charges it back up. So as not to damage the battery. It keeps following that loop to keep your battery running longer so the first 10% can sometimes be misleading but it's nothing to worry about

This was fairly common on the SGS2.
The common way to fix it on that device was to charge it to 100%, then unplug it and plug it back in and wait until it gets to 100% again. Do this 3-5 times and the problem should be gone. It is worth a shot on the SGS4
This can happen when flashing ROMs while your battery is not full, though this is not the only way for this to occur.
I like that last one. Gotta try it out.
The kernel stops charging at 100 percent and doesn't start again until it guys 95. What you're reading as your percentage level is not the exact levels
Say you unplug at what you think is 100 percent but in reality it's actually 98 percent, the software quickly relays this back to the user and adjusts the battery levels accordingly making you think it just drained 2 percent really quickly.
The whole reason it does this is to percent over charging the battery. That will greatly shorten it's life cycle or even worse blow up your battery
