[UPDATE,FIXED] Battery lowered 10% in 2hrs while on Airplane Mode/ Wifi Off.

I was in a class that is from 7AM-11AM. The classroom has no signal whatsoever so at 7AM I put airplane mode on, didn't turn on Wifi, closed all open tasks and just for the heck of it turned off background data.
When I put all this into effect, I was at 91%. At 9AM I see that my battery went down to 81%. How is this possible? I was in airplane mode so nothing was synching or downloading, no programs were running in the background or anything at all. On my previous phone (Nexus One) under the same situation the battery would have been at 90%.
Phone Idle- 34%
Cell Standby- 30% (Time without signal 85%)
Am I missing something here? Can someone please elaborate why this went down so much for basically doing nothing.

Did you drain your battery completely the first 5 to 10 times charges, when you first got your evo? Many people claim that's how to he the maxium battery performance from your battery on any phone

Normal. I lose about 10% every 2 hours.

Yeah but I wasn't even using it and it was in Airplane mode. That can't be right

WOW... sounds like its your CPU thats still killing the battery??? You don't have it rooted or running any cutoms ROMs on it?
We SERIOUSLY need to get a UV kernel on here and underclock this thing when its asleep... So many battery drain issues.
Your issue is REALLY strange though.. I was in LA yesterday and mine didn't drop that fast for like 2 and a half hours... Very interesting......

This is bogus. Don't bother doing this. That was something that was needed back in 1999 back in the days of NiCad and NiMH batteries... It doesn't help LiIon one bit.

20 hours of battery life is pretty good. I think the record is like 62 with everything completely hacked down. I get about 4-6 in full on usage.

I understand that 20 hours of battery life is good but If I was using the device in those 2 hours I wouldn't be worried. But I wasn't, it was completely IDLE with all the radios turned off and programs killed (advanced task manager).

that is NOT normal lol when my phone is on standby i loose about a percent per hour overnight....

Deactivate any syncs you don't use. Make sure your phone is set to CDMA. See what processes your phone is running that are killing the battery and disable them.
I get about 27 hours on my battery.

I fixed the problem. I rooted 2 days ago (evening) after getting such bad battery life and I flashed Damage Control 3.0.
Today after 2 hours and 30 minutes of being under the same exact conditions as my original post (30 minutes more this time) with Airplane Mode, Wifi Off, Tasks Killed,etc I only lost 1%.
I went from 93% to 92% in 2 hrs/30 minutes which is a hell of a improvement in comparison to losing 10% in less time (2hrs) with the same exact circumstances.
I am extremely happy now. Oh and by the way, yesterday I got 14 hours of usage with this ROM which for me was unheard of before (4-5 hours)

battery and rom help

We I am rooted and have tried several different 2.2 roms and kernals with no luck on battery life I can get 16-18 hours out of a charge with minimal use. Does anyone have any suggestions what i can do. Is there a go to rom and kernal? with all of the 2.1 roms i would get a couple days out of a charge. All i really want is to go at least a day without recharging, it sucks when im out and my phone is flashing red around midnight and ive barely used the phone all day.?!

16-18 hours? Jesus, I'm getting maybe 8-10. You should feel lucky.

check out Ava V9 + Netarchy's aggressive undervolting kernel. I swear thats the best combo ever. Battery life gets better daily with it, right now, its "meh" but it feels like its improving. First time i flashed it, my phone wasnt sleeping and it was dying while the screen was off, but wasnt losing any power with the screen on. So i let it die, charged it up to full, now it hardly loses power with screen on and off.
I'm only on my second day with it though, but its pretty amazing. And during the weekdays i use my phone heavy. Constant texting + music + twitter (3min refresh) + autosync + angry birds + wordfeud + space physics + browsing. I use my phone instead of my laptop, so thats why i have all of that going on, so from 6am till noon, i only have the screen off probably for a total of 30 minutes, everything i listed above is being used and it makes it to 60% battery left. As soon as my battery hits 20% it takes forever to drop, 10% takes even longer.
tl;dr Ava v9 + netarchy universal aggressive undervolting is the bees knees. try it out, not promising the same results taht i've gotten, but its always worth a shot
Edit: Also OC'd to 1.22GHz

Yeah but how much do u use it, on an average day i might send 20 texts and talk on the phone for 20 minutes and check fantasy football for a few minutes, if i even try to play games its like each minute of usage correlates to a 1% off my battery, gps off bluetooth off no 4g occasional wifi here and there and i even turn off mobile network which helps but i just feel like the amount i use the phone it should last longer

Since my last post I've tried my best to mimic your usage (i went way overboard on the texting, but thats good in this case). For the game, i chose to play Angry Birds for about 30 minutes. I also played a sht ton of WordFeud, since I cant go a day without dumping a lot of my time into that game. I browsed around on my browser and even downloaded some crap. Had WiFi and 3g on for most of the time.
So far im at 47%. I started at about 2pm and it's 2am now. Im going to sleep at 2am right now so there will be that idle time.
Edit: Just now woke up and I'm at 42%. Battery Indicator indicates that my phone has been on for 19 hours so far. Ava V9 + Netarchy's universal kernel may be the set up for you.

well ive had it on for only an hour so far so good... thank you for your time

Can you not find a charger within 16-18 hours?
Don't sweat the small stuff.

16 hours is good, why not just plug it in when you're sleeping?
I can go a good 24-36 hours on a charge and I'm using the phone 100% original.

I charge it all the time, before i leave work, when i sleep, in the car if i have to, it just sucks the few times i dont get a chance to charge the phone and im out with friends and i cant even use the phone because its like once the screen is on its time for rapid battery drain. Last night i lost 15% in a 7 hour span of not using the phone once. I even have set cpu set to the lowest setting when the screen is off?

Thats what was happening to me at first. With the screen off I lost all the power but with it on, it was all good. Confused me, so i went into recovery and just wiped cache and dalvik...dont think it did much, but i just let the phone die. The next day, it seemed better, the day after that, a lot better. There are some kernels where you barely lose anything while the phone is sleeping...but with this one, its like the opposite for some reason. Which is kind of a good thing and a bad thing at the same time.

I use Ava. I have a battery thread in the general forum.

Horrible Horrible Battery Life

Hi guys im wondering who else have a really really battery life, it drops so quick :S
i have brightness low,and seems its draining fast. i tried stock for a little and seems it drops not so fast but still fast, i compare with my old evo and wow was a beast it can last tooo long before drop 1% and htc one X its giving me so much issues i tried insert one coin, and im now on leedroid (seems better) i have to get juice defender ( i never have to use) using hard my old phone (EVO 3D) drops like 50% in 4 hours of Hard use, 2.5 hours bluetooth headsetplaying music, some browsing, whatsapp, twitter and facebook. sometimnes drop 60% its not so bad, perhaps yesterday in almost the same time and doing a lot less drop from 70% to 0% idk what happening or if this is normal because screen? anyone has this issue?
or maybe we can do a "test" maybe playing a video for 30 min or something wifi on, just to test.
Maybe could be my radio? im using HK htc one X in mexico, the 3G works great perhaps could drain more battery?
Any help i will apreciate thanks a lot, i love the phone but this sucks
Regards

How long have you using HOX. I am getting 1 day of battery life after heavy use.

Have you tried battery test, or safe mode?
Sent from my HTC One X using XDA

i have +/- 40 hours, average use,
its like my sensation, with 1730mAh battery (well in my sensation with bricked kernel i have +/- 50 hours)

wow make me feel like my battery its faulty (hope no)
well i have been using for 1 day i hope last well the next days LOL my warranty its void due unlocked bootloader xD damn i hope works well i will try charge when the phone its off, i should try make a "battery tester" i mean maybe some benchmarks? like doing some stuff and see how much battery drops, decoding and so on maybe for one hour and compare between phones to see if you have issues or something, no one has done something like that?
Thanks a lot i really like the phone i hope its just something to get fixed soon
i really apreciate all comments, and make me feel bad lol i

screen on time?

Drain the battery completely and then charge for at least 8 or more hours, use the phone as normal and let it drain completely again and then charge for a minimum of 3 hours, after a couple of days it should last longer and if you can or need to upgrade to the latest OTA then do so.

well that is not really helping him is it. no point you telling him you getting that kinda of use of out the battery..it is like rubbing it in his face
but anyway 3g does drain battery specially if the signal is low and it is trying to find the best possible signal for you. only use it when you need it. same goes for wifi. for wifi i would have it to sleep when screen is off.
have a look in the battery stats thread and few people give tips in there on how to extend the battery life mate.

if i was you i would not let it drain completely..let it die down to say 5% i would then fully charge it like overnight. then go here install that apk and once you have fully charged let the battery drain again. once it drains to say 15% check what wakelocks you have. that will help you see where the issue lies and the battery gets drained..better explanation on the thread i gave you the link of mate

if your carrier still shows that you have updates then i would say do that as well mate. radio as far as i know we can not flash just as yet as we need s-off to do that so your best bet is the OTA if you are not on the latest firmware

Wait & see what the battery lasts like after a couple of days of charge & discharge, mine was poor on the first day.
I always try to charge mine up over night & my battery lasts on average 40 - 48 hours now.
The other day i had wi fi on & gps on read some of a book, 3 or 4 calls 5 messages & used a gps app for a while had just over 2 hours of screen on time & after 14 hours still had 60% battery left.
There is no reason why your phone wont get that after a couple of days, hope it is the case for you

Estoy orgulloso que tenemos mexicanos que tienen un One X
Hopefully as updates come, battery life will improve

I´ve been using the HOX for 5 days and it does get better after you run some cycles, but I still find it´s not as good as the battery life on the GS2 I used to have (I was running the Illusion rom).
With the GS2 I would leave the brightness at full blast, I would watch about 1 hour of video, I would use the calendar a lot, I would make a couple of calls and by 19h when I got home my battery would be around 80%. I do the exact same things on the HOX and I get a little less than 70% at the end of the day.

It happens to me as well, but only if I turn on WiFi and let the phone use it´s online services.
Hoping that the Jelly Bean update with Sense 4+ brings some kind of optimization.
I have my HOX configured pretty much like my SGS3 and my S3 lasts 20, 30% longer and about 7ºC colder.

Same here, kinda want to change my phone again if HTC doesnt fix this problem.

do a battery calibration, app like this works https://play.google.com/store/apps/details?id=com.nema.batterycalibration&feature=search_result
before the app 1 day usage = 60% of power left
after = 85% left
HTC made too much of the safty triggers for the battery if u use it lightly every day its minimizing side effects by making new one (less charge)

How long have you had your One X, OP? It takes several full charge cycles for the battery to calibrate, it's one thing about One X that's weird. I remember being completely disheartened with battery life when I first got mine - and it was horrible, pretty much like you've described it, 1% every minute or so - but only kept it because my mobile operator wouldn't replace it before making sure there is a hardware malfunction, which could have taken weeks, and I was impatient. Then I learned from xda that this slow calibration phenomenon is a thing with this phone.

I hope you're right svucinic811 I'm really getting worried here

I am wondering what a good rate of discharge is cos if i leave it on standby overnight it went from 99% to 79% in about 8.5 hours. personally i think it should have been 99% to 89% in 8.5hrs but anyways...

Will this work even without rooting my phone? I'm running on Stock Sense 4.1, but this seems like it would help a lot.
As well, if you (for a couple days) go without charging your phone in the middle of the day and let it run down until you charge it again I think you will see some results in the battery life. My battery would die everyday before school ended for me (Wake up at 7:00 AM, Phone dead by 5:00 PM). Unless it was just a placebo affect for me, its worth a try.

Does anyone else has this problem where, yes the battery drains fast, but takes forever to get charged to 100% ? FYI, I'm using the real charger, not via PC~USB

how do i calibrate betterbatterystats?

What's forever? 3 hours is about normal, unless you're heavily using it.

You don't have to calibrate Better Battery Stats. Just charge it up to full, then wait for it to happen again. Open it up, choose Since unplugged (obviously you should not have plugged it in at any point of time since the full charge), then take a screen shot of Kernel Wakelock, Partial Wakelocks and Process.
@Rohin, USB Cable quality plays a big part as well. A cheap rubbish USB cable even connected to the wall socket charger can only charge at 300+mAh, while a good one can charge up to about 750+mAh. About 85%-90%, charging usually slows down to about 200-300mAh, then slows down even more as it approaches 100%.

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

It went down TO 2% not down 2%.

That's not what he said. Read it again.

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
