Sudden drop in battery from 65+ to 20+

I was using nav app when my phone froze for some reason (first time ever it froze). I restarted the phone n the battery fell flat from 65 something to 14. I was shocked. I restarted again n this time it came to 28. Couple restarts n it still was at 28.
Can anyone pls help me understand this.
I never had any issue with my battery whatsoever so far and find this a lil unnerving.

Have you looked into the battery log to see if anything in particular was drawing it? Possibly Android?
It has happened to me twice. Pulled battery for a minute or two and was good to go. No rhyme or reason and not a regular occurance. Happened on two different GB roms also so I cannot pin it down.
Good Luck....

This I know. That's where the screenshot is from that I posted in OP. I was thinking probably like a log file.
And it there, it doesn't show anything. The pic clearly shows drop in battery level after a restart.

Our fuel gauge sometimes flakes out. Either search General for "gingerbread fuel gauge" for info on how to reset it, or just pull battery for a minute or two - that'll reset the fuel gauge.

OK so take this post and i can say word for word that it happened to me.
I was fishing with a friend yesterday and while taking a photo of a great catch, my phone froze....which it has never done. I restarted and my battery was in the red, rebooted again and battery got higher but still half of what it was before the freeze. Like the OP, I had my gps on when I took the photo and had been using the navigation just before.
Recalibrated battery and does not seem to have a problem after a full day after.

like entropy512 said - sometimes our gauge just gets thrown off.
every time i have to pull my battery (phone freeze, flashing - whatever) i generally lose at least 10%.
i have never lost as much as the OP did in one freeze... but my guess is that he just hadn't pulled the battery in quite a while, and therefore his gauge was super inaccurate.

Well, I never pulled it out ever since I got the phone until this happened. Now its back to normal

Yeah and i recalibrate my battery regularly.... So it wasn't a "fuel gauge" issue....
Even still, the point was that whatever happened was caused by the gps and/or navigation...

Recalibrate? How? I am sensing that you don't understand how our fuel gauge works if you tried to apply a recalibration technique for an HTC phone to our device. This is a classic fuel gauge flakeout. It will just decide to go bonkers for some people unpredictably, I haven't figured out why.
On our devices, battery pull = recalibration - that's it. There's a software shortcut and it is NOT to wipe battery stats, search for "gingerbread fuel gauge".

I have no option but to agree, though partially... cos this happened after the phone froze up when using navigation. So looks like its got something to do with that.
I don't think the app wud use up battery from 65 to 14 within 2-3 mins. It froze within 2 mins of starting nav from maps, and I rebooted the phone using the power n volume keys.

My guess is more likely an I2C bus freeze or some other weird low-level thing borked up the fuel gauge chip - the CPU hanging in the middle of a gauge read operation might do something funky like that.
Navigation can do NOTHING to touch our fuel gauge chip, nor can anything drain the battery fast. Also, as you see, the battery estimate started going upwards after the "jump", which is a clear sign that the fuel gauge wacked out.
If it happens again - check the battery voltage. If raw voltage stays high and SOC goes low, your battery didn't discharge, it's just being misreported and a battery pull or SOC reset (Note, this is NOT wiping battery stats - if you haven't found my gingerbread fuel gauge thread in search, just do a battery pull) will fix things.

[q] why does mobile data cause so much heat!!?

The phone getting hot doesn't drain your battery more... the fact that mobile data uses more power than wifi makes your battery drain more. That is also the reason for it getting warm... nearly every smartphone I have had with 3G has done this. Normal.

My dhd never got hot when using mobile data
Sent from my HTC Sensation XE with Beats Audio

Neither did my Hero.
This sucks. My Sensation apparently can only browse the Internet using mobile data for 2.5 hours before the battery dies. I'm pretty sure that's not the case for the SGSII either

My sensation gets pretty hot to, but that wouldnt be such a problem if the batterylife would be good. At the moment my battery drains about 8%/hour when it's idle... so i have 12,5 hours stanby time! that sucks -.- I'm gonna get a Anker battery soon and hope it's gonna get better with that...

If you get 8%/hour drain while idle, and truly idle (i.e. your phone is truly in sleep mode) then you've a faulty model - bring it back

Well i don't know how it was with the stock rom and anything. And i don't have any longtime informations with custom roms, kernels and so on, because i just recently flashed a cr.
But today I unplugged it at 8:30am and it had 100% at 10:30 it had 84% and now it has 70% and from 8:30 to 10:30 i was only on facebook and surfed a little for maybe 10 minutes or so :S
Now I flashed Bricked Kernle v.1.5 i hope that its gonna be better with that.

Do you know if you're phone is actually sleeping when the screen is off? To check, go Settings - About Phone - Battery. Here you can see Up & Awake Time, but to see more accurately, click on Battery Use, then click on the graph. Look at the Awake bars and make sure they correspond to the Screen On bars.

The screen on/off and active bar are almost identical. There are some little tiny active times when the screen is off, but thats probably some syncing...

Faulty model, return it! On (real) standby (which the image shows you have) you should get only 1-2% battery drain, even on Sensation

Don't think that's true.
For one, there was a few weeks when my phone did not heat up like crazy from normal usage and I could make it last 2 days. Then one day it started heating up like crazy... also plenty people report 2 days battery on moderate usage with Sensation - i.e. no crazy battery drain.

Could it be that my phone is alright and only the battery is faulty? It would suck to return it -.-

It's not a faulty model. There are no known issues with standby drain on any sensation.
Notice the image shows times with poor signal too. Additionally he may have auto sync handling too many accounts.

It's getting better with the ROM I'm using at the moment and i orderd a Anker battery. I hope it's gonna get even better with that beauty

I can't explain any facts, but I really don't think slightly higher battery drain is because of a faulty phone. I've owned two Androids and tinkered extensively with many, many others. Most Android phones seem to be awake similarly to that one user's battery graph. It's normal.

Awful battery life.

So I just got a replacement device and after 3-4 full charges and discharges, this is the battery life I'm getting.
My first device lasted almost 5 hrs screen on time on the first charge out of the box.

How about doing a factory reset, reinstall the RUU, and running a couple of bat cycles before installing anything (other than XDA of course, lol). This would let you know whether the phone is a dud or not.

It's strange. I've noticed that some (most) units get great battery life, but there's some out there that are abysmal like yours.
I'm on my 3rd One X and this one gets the best battery life of any smartphone I've ever had. I could easily go over 24 hours and get several hours of on screen time. My first unit was just as good but took it back because I dropped it. My second one was noticeably worse although not as bad as yours. If a full factory reset doesn't do it take it back for a new one.

HTC must be using different suppliers for the batteries like they are for the panels.

My Rogers unit had terrible battery life with LTE turned on with the stock RUU. (1.73 I think).
I got decent battery with LTE turned off (menu for Rogers or *#*#4636#*#* for ATT). Then I upgraded to the latest ATT RUU (1.85.502.3) and I get great battery life even with LTE installed.
So try turning off LTE for a day and/or move to the latest RUU.

Try this one. Fully charge your One X. Turn it off and put it on the shelf. Turn it back on the next day. It won't turn on. The battery will be completely DEAD. Happens every time for me on 4 different phones. Something is sucking the battery down when its OFF.

Yep. I have been playing with a few phones, the nexus and the note and been shelving my hox. Everytime I turn it back on its DEAD. Makes no sense.

Same thing has been happening to me and others, phone will be running great, then all of sudden warmth around the camera and quick battery drain. Info in Android Central thread: /htc-one-x/174836-battery-just-drained-very-quickly-weird.html

Go to settings then power and uncheck fastboot. Your device should no longer die while "being off". At default HTC settings fastboot is turned on (not adb/bootloader type fastboot) literally it doesn't actually fully power down the device so a faster boot time can be achieved.

It could be Apps. I was running my One X with minimal apps installed (just essentials), and battery life was fantastic. Now I installed a bunch from the play store, and my battery life has become similar to yours. about 45 min screen time and 6.5 hrs total and down to 45%

[Q] Phone overheating

Pretty much since the summer in my car where the first accident happened my phone tends to overheat a lot(when charging and sometimes when using gps).
Yesterday while charging it in my room and playing a game the widget showed the phone at 50 degrees Celsius.
When I saw it I immediately turned it off, and took the battery out so it will cool faster, the battery didn't feel so hot tho.
So what may be the issue? defected parts? or maybe it's just the sensor? Any way of finding out?

While on gingerbread, I never got a message about charging needs to be stopped because of overheating. But since the stock ICS 4.0.4 rogers update, I see it almost every day. I guess I'll wait & see if there's an update to 4.0.4, or for the 4.1?

Hi, I had very similar issues...it would overheat even when NOT charging or using GPS. Of course, this only started happening once summer hit in NYC (around end of May).... I did a lot of research and this has helped me TREMENDOUSLY. YMMV, but it's something to look into.
First, I flashed a kernel hack from here: http://forum.xda-developers.com/showthread.php?t=1437563
Then I installed GideonX's battery tweak script from here: http://forum.xda-developers.com/showpost.php?p=20946429&postcount=574
Not only has the temp become more stable, I get better battery life. Of course, you're effectively under-clocking the device, but I haven't experienced any performance degradation with any system intensive apps, like games, etc....
Let me know if this works out for you! AND READ EVERYTHING BEFORE YOU FLASH!

Thanks I'll check it out although im already uc+uv. today I reached a new record for 57 degree's Celsius.
Also you linked GB kernel I'm on ics but I'm using mohans kernel.

Even my phone geys heated up... I guess it's a problem with most android phones... But actually as such there is no solution out.. Nd i guess it isn't causing much of a problem also!

Forgot to write..... Dude 57 degrees is a hell lot.... I guess there is a serious problem with your hardware or maybe rom or possibly kernel... U must seriously try to identity the problem!

Not sure if this will be at all helpful either, since it takes about 7-10 days before it shows any results, but it's worth a shot. It's a crowd-sourcing app called Carat: https://play.google.com/store/apps/...iZXJrZWxleS5jcy5hbXBsYWIuY2FyYXQuYW5kcm9pZCJd

well the 57 degrees were achieved by leaving the phone in the car in the sun with the gps on while talking to a friend outside for 15-20 mins so it's a rare occasion but it gets to 50-52 when charging+dps mid day.
Installed carat and let's see what it says, thanks.
I think my main issue is the summer here, it never overheated in the winter.

If you're driving with the phone exposed to the sun, it's going to get hot. Even larger devices that can dissipate heat better such a tablets will over heat in the sun.
I recently started running 192min 1.08max which appears to have helped slightly. I mostly did this to see how it'd affect battery life though since I haven't noticed any performance changes.
Still, if you're charging, gps, and to top it off are in direct sunlight on a hot day, any device will get hot. I don't think there's anything you can potentially do to fully solve this other than clip it onto a car vent to run air over it while out of sun's view.
Sent from my SGH-I727 using Tapatalk 2

Actually I am positioning the air conditioner to blow on the phone but the car mount blocks most of it.
I guess the phone can take the heat no prob, I'll just have to get a new battery once the heat kills it because I heard that lithium batteries are sensitive to heat above 45-50 degrees Celsius.

[Q] average or bad battery life?

thinking about getting my battery swapped if VZW lets me (have had the phone since 7/10).. if not, then get a new one. but before i go into the store, i wanted to see if you guys think this is normal battery life from these screenshots. i have GPS off, Google location on, and only my Google account (Gmail, contacts, calendar) is in sync. i'm running a rooted stock rom (debloated VZW and Samsung apps by me).
in addition, the back of my phone gets really hot during regular data use (web, Facebook, Instagram, Engadget and Verge apps, ESPN, etc.. no games), to the point where it's uncomfortable to hold. i've heard that there might be a batch of bad batteries for the earlier shipments, so i was wondering if mine might be one of them. thanks for any input.

Do you have 4G on at all times? I think my battery might be pretty bad too...I've been losing 10% every hour, so my phone pretty much lasts only 10-12 hours. I'm impressed by your 1 day battery life. Even if I have wifi only on and turn 4g off, I still only get 10% every hour. I think something might be wrong with my battery...I've factory reset it many times before too, wiping cache, and dalviks, I'm now on the stripped rooted stock.

that's not bad battery life. Especially sense it looks like you are not in great coverage area.

from what I understand, these phones tend to get warm after lots of screen on time. so I believe thats normal.
I would accept your great battery life and call it a night.

I get up to 8 hours with 4g on at all times with heavy use. Phone only gets warm when i got the charger in it

After using the Chrome app for 30 minutes straight, my phone doesn't get noticeably hot. I've also used the Engadget, Verge, and Facebook apps for 10+ minutes in a row, and it doesn't get hot. The only time I have seen it get hot is playing games and charging. Even then, it's not bad.

I would say you have a gold battery lol, I rarely even get 18 hours on my batter even when 12 hours of that is just standby/listening to music.

haven't had a proper measurement of the temp, but it feels like it does reach the upper 90s, and that's with light web browsing, so that's what worried me.
it's just that i see people who claim "heavy use" and get 4+ hours of screen time, which i found hard to believe, if they really are pushing the phone a lot, so i just thought maybe something's up with mine. thanks for all the input so far.

Looking at your battery consumption log, I'd say your battery life is pretty great.
Seeing as how your cell standby is 50%, you're either using a lot of 4G or you're in a crappy signal area. Or both. Haha.
Even if you buy a new battery, chances are that you won't get better battery life. Just charge the phone overnight and unplug in the morning. As a general rule of thumb, if you can squeeze 16 hours of usage out of your phone, you're doing pretty great.

yup, that seems pretty darn good to me. I get about the same 4G coverage as you with Verizon in my home 2-3 bars max (-100 to -120dBm), and I get ~14 hours before my phone is about to die. I also think I just use my phone a lot more than you lol. You only had 2.45 min of on screen time in a little over 1 day. I usually have close to that in the 12-14 hour days with my phone.

Agree with last two post...what else are you looking for looks good....

Should I ask for a new battery? 3 hours 30 minutes 30 min screen time and down to 67% battery.
