The one of mine used last night more or less the same, around 10% with wifi, no apps running, no data conection, etc. I'm a little bit worried about it, i think it's too much battery drop :/

Tonight, in almos 6 hours my battery has dropped around 4% being in airplane mode. I have installed betterbatterystats and i cannot see anything strange
what used up the 4% that is not strange?
I unplugged my phone at around 3am because I rolled over and noticed the notification led blinking. I was at 100% and cleared the notification. Went back to sleep then got up around 5:30am and looked at my phone. I noticed my battery was down more than I expected so I checked the stats. I was down almost 20% in 2 hours 30 minutes. Android OS was at 60% usage with time on a 2 hours 20 minutes. I had sleep assist turned on during the night and I also keep wifi and data on. I've installed Wakelock Detector to see if it will be able to see what in Android OS is keeping my phone on.

fyi. when you charge your phone, the battery starts discharging once the battery is FULL, NOT when the cable is unplugged. However, the battery % will not drop whilst the phone is plugged in,
Therefore, if you charge your phone fully but don't unplug it for hours, it 'may' appear to discharge faster than normal once you do unplug it. (basically the phone will over present it's true charge level).
If you unplug the phone as soon as its fully charged, however, it will appear to discharge more slowly...

actually you are just partially right. the percentage only drops until reaching a trigger level, where it starts to charge again. also in my opinion when the phone is charged and left plugged in it uses the power directly and leaves the battery untouched

Hogwash.
Lithium batteries don't retain a memory.. You can charge them as often as you want... No matter what percentage your at. And if you leave it plugged in it will keep your battery fully charged with a trickle charge at 100...
I'm not sure what wives tales you've been reading.... But not everything on the Internet is true.... So you know.
I read something else around here lately where a guy was saying basically if you plug in at bedtime, you better wake up after a couple hours and unplug.... Or you'll damage your battery. Lol
Anyway.... Charge how ever you feel you need to.... To each their own. But I guarantee your battery will not drain quicker cause you left it charging all night.... That's simply ridiculous.
No offence.

its not hogwash, I think maybe you misunderstood me. I'm well aware lithium cells aren't memory cells. In fact, check my post history I posted as much in a thread of someone asking 'how best to first charge their moto G'. So if this is what you thought I meant, fairplay.
However,
Someone clarified above there is a 'threshold' level. however, these phones do not 'trickle charge' it's not a car battery. Charging at full amps when the battery is full would damage it, hence it stops charging, starts to discharge, then at some 'threshold level' will begin charging again, it does not trickle charge..
Also, as a matter of fact a friend of mine is an electrical engineer, does small Linux projects and some work on ARM architecture. I first heard about this behaviour when charging whilst on the XDA S2 forum. We tested the charge in the S2 1650mha battery ourselves and found we could get a variety of charge levels all shown as '100%' on the phone, just by when we unplugged the charger. I'm making an assumption this phone behaves the same, however why would it not?
So, all I would say to anyone on this forum. Just because someone has a lot of posts and thanks and 'knows his stuff' , This guy should take his own advice and not believe everything he reads on the internet...

This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.
The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.
I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS
widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

Cell Standby 23%
Phone Idle 16%

Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%

Would anyone suggest Advanced Task Killer or Juice Defender?
There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.
I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!
Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?

as far as i know, its an known bug
Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.
It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%
96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%
Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?
I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.
You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.
Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there
Turn the tethering on while charging; it'll charge the battery up to 100%
I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App
Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.

Hey guys, I have a problem with my Sensation. Whenever I fully charge it and then remove it from the charger, use it for like an hour or two, the phone still thinks the battery is 100% charged. When looking inside the battery usage, it shows the graph with 0s underneath it, while in the previous screen where you see the apps battery usage it says 2h 5m 13s or something like that.
This wouldn't really be a problem, but when I started up Maps Navigation and plugged the charger in the car, it wouldn't charge because it still assumed the battery was 100% charged!
Any of you also having this problem? Thanks in advance!

Does it stay 100% forever? Then you may have the inexhaustible battery... (not sure if this is grammaticaly correct )
I wouldn't consider this a problem. You can download a battery monitoring app from the market and see what's going on with your phone and if the 100% that it's rerporting is correct. Also, check that the battery contacts are clean.
Not sure my phone does that but it can be on half charge then when I reset phone it's gone up a notch. This morning it didn't look like it had charged although it had been plugged in. When I switched it was on orange then it did the charging animation for a few seconds without charger plugged in then stopped on full. Odd.
Mine stays on 100% for a couple of hours too, has done since I got it.
I think perhaps HTC are "cheating" (or using "creative coding", whichever expression you prefer) in the way they report the battery percentage. Make the battery appear better than it is. Just a theory, of course.

That happens to me a lot too. Woke up this morning, phone had been charging for nearly 5 hours, but was only on 82%. After a couple of minutes of the screen being on, it had leapt to 100% and stopped charging.
Also, once the battery is below about 20%, it will sometimes drop 2-3% at a time. Odd.
Looks like they totally screwed the battery meter hardware or something in the software. Remembers me of my iPod touch
Experienced the say.. hopefully either it will auto be fine due to charge cycle or via updates

Charge the battery with the power turned off overnight, in the morning unplug the charger, turn the phone on, and shutdown again, and plug the charger back for 30
mins phone still turned off. After that start using the phone normally, this way you calibrate the phones battery meter properly.

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?
I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.
Thats exactly what I did, I let mine completely die and then charged to 100%.
Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.
I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally
Mine came dead! it didnt even turn on. so I'm charging it now

That stinks. It must have been on in the box like that other xda member on here claimed

Mine came with 1% battery so I just turned it back off and now I'm charging it up, i think the led will turn green when it's ready

How do you tell if the phone is charged to 100% while off?
While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?
Update: NVM last 1% just took forever. LED does turn green when fully charged.

The LED will turn green once it's 100%.
Don't worry about letting the phone die and charging it up to 100%.
These batteries don't have a "memory" like older phones

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.
Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow
Why would you buy it? Pretty sure they would give one to you for free

bought it off Kijiji
It's offered by Rogers, but i'm on Telus
Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .
guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.
im qualified in lead acid. ni cad. nimh and lithium batteries. trust me..u cant hurt it unless you short it! !

So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

The best source is battery university. Here are a few good links. In the first, look at the third column (Li-ion), as that's the battery pack in the Maxx/Ultra/Mini
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

And boom! All the I have known through all the androids I have has been wrong lmao. I really appreciate you posting this....all the years of trolling forums and reading what everyone is doing or have done to get their battery to last long for a daily cycle...appreciate this.

So happy I seldom charge up to 100% and leave it sit. I also never let it get super low.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.
