Battery drainage on HOX

My battery on the One X I think is bad, when I check facebook or Twitter on WiFi, it drains 1% every minute and it annoys me. Playing simple games also drains 1% every minute...really annoying. Is there a problem please help?

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...

It should only discharge at most a few percent. Check your wakelocks with BetterBatteryStats.

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%.

So give it about a few hours on standby and then run BetterBatteryStats, then select partial wake locks from the drop down box and it should present you with a list of the wake locks, easy enough?

Battery 40% sudden drops issue- please come to help

hey guys
I'm new to GNex (3 days user here )
my nexus has a serious battery drops when it reaches to 40% on every roms and kernel!!!
it is like this that when battery percentage is under 40% it drains super extremely fast even w/o any usage to nearly zero ( in about 20 min ) of course some times it even does not get to 20% and phone shutdown!!!!!
i also calibrate battery but no success .
( my battery usage above 40% is normal and i get nearly 3+ hours screen on with moderate usage but it sucks below 40%)
any help/suggestion/etc is welcome.
thanks in advance
edit: screen shot added
**********************************************************************
i notice several nearly same topic but no one exactly mentioned to my issue so i created a separate thread
sorry for spamming

Do you have consistent network signal throughout the day? Just saying as 40% may have been reached by the time you get back home, for example.
Have you checked if your phone wakes up too often - triggered by some application?
(Further to above example, perhaps some location based applications starting up?)
A screenshot of battery usage would be nice.

When you say you "calibrate" your battery, what exactly do you mean? If it's wiping battery stats, that has nothing to do with anything even remotely related to battery charge or indication.
From the screenshot you posted, it looks as though your screen is constantly on. That's another tangent, though.
You'll need to try a factory reset, but be advised you'll lose your data. If that doesn't fix it, then you're likely looking at a bad battery.

It really bears mentioning that there's no user calibration of the battery. Anyways, if this is happening regardless of rom, then you're looking at it being defective hardware. You'd want to first try a new battery. If it still exhibits the same symptoms, the problem would be the phone itself.
Sent from my Nexus 7 using Tapatalk 2

You could try and rest the phone (switch wifi off, screen off and keep phone unused), and see if the drop is still drastic after say 50%.
Tried the ZenSeries v8/9 too? I had good battery times with that, close to 4 hours screen time with 25% remaining.
Do check what month the battery was manufactured on, and if it's a recent manufacture month, it may be faulty.

I have the same problem too with my Yakju. I am using stock ROM updated to JB 4.2.1 manually. Battery drops dramatically from 40% when sitting idle.

[Q] Short battery life

I've had my Galaxy W for just over a year. Whilst I was running the stock ROM I would more or less get a full day out of the battery. I upgraded rooted my device and installed the Cyanogen CM9 rc2 ROM. I don't recall any battery problems at first, but just over a week ago it started draining within five or six hours. This happened every day for a week.
Since then I have uninstaleld all apps (apart from Google Authenticator which I couldn't manage without), turned off wifi, bluetooth and everything else I could think of. Now I seem to be getting about 36 hours out of the battery... Although I think it goes from 35% down to 10% very, very quickly.
Leaving all data connections off and having no apps is okay in the short term, but is there a long term software solution?

Not immediately, but about a week later. Is it worth going through that process again?
Edit:
This is the app that I used:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en

Before I uninstalled any apps I downloaded and installed CPU Spy. Here are two screenshots taken with CPU spy.
I could reinstall it now without any other apps installed, if that will help?
I don't know enough about this, but I expected that the phone would spend a higher percentage of it's time in 'deep sleep' than that.

That should have been right. I don't know what is happening with your deep sleep, although your phone is on for 16 hrs but the deep sleep only reach not almost half of it. Did you use your phone often?

Interesting.. how about you check on the battery is it bloating or not?
For battery problem is either the phone calibrated wrong readings on the battery or the battery it self is the problem.
If you use your phone not too often but the deep sleep only reach 34% of the time then some apps is preventing the deep sleep, try to check what apps is that causes that with some battery stats app, try search it in xda or market

I've gone for Battery Stats Plus. I'll reenable wifi, bluetooth and 3G for a few days and see what happens. If that takes a toll on the battery I will post back with details from Battery Stats Plus.
I will also take the battery out later to inspect it.
Update:
My battery had 15-20% remaining and I turned it off, and tried to turn it back on. It now thinks that it does not have enough power to boot the phone. I don't know if that new information is helpful or not.

With 15 - 20% it should have boot, because it still have juice left. What about your battery physics? Is it bloating or just normal?

Took the battery out this morning for a proper look. There's definitely some bloating. Time to get looking for a replacement battery?
Could there be two issues here? As from the screenshots I posted the phone doesn't seem to have spent a lot of time in deep sleep.

I was just watching a YouTube video, with about 70% battery. The phone turned off, and when I've turned it back on it's gone down to 2%.
Could this be down to an improperly calibrated battery, or is it purely down to the physical damage/bloating to the battery?

I'm going to install Battery Calibration by Nema from Google Play. I'll see how I get on with that.
I'm going to order a replacement battery this week. I'm looking for a direct replacement, with an official Samsung battery. I have posted here in the Accessories forum. I hope that was the right place to put it.

After I install the CM10 alpha 6 conform to the first post, the battery life of my cellphone has been drained very fast - 21% about 6 hours and half.
Can anyone help me, please? I already did the battery calibration and I can't see effects. I'm wondering if is better install CM 9 or just go back to the android 2.3.6 factory version of my cellphone.

Your battery is bloated? Then you *must* replace it. Period.
A damaged battery is the root cause of myriads of problems. Until that battery is replaced, you _will_ experience all kinds of annoyances, no matter what ROM/Kernel you're using, including inexplicable battery drain.

BATTERY CALIBRATION
Hi!
As we know when we install a new rom we sometimes have battery drain or when we flash a new kernel etc..... what is this?? this means that your battery goes to 0% very quickly!
The normal steep is goes to recovery and wipe battery stats!!
but what i do if in recovery don't appear something like wipe battery stats??
simple!! be sure that your nexus is completely charged,download this app ,, tap on battery calibration !! (after that charge your nexus without break)and congratulations.... buy a beer and make a party!!
I don't made this app.... just share it....
i will upload the link in a note pad... why?? simple.... i can't put links!!!

There is no need for battery calibration. Just discharge to 0% then charge back to 100% and you should be good to go.

mmmmm thanks for the page....

The myth of wiping battery stats was thoroughly debunked almost a year and a half ago. It is a 100% true statement that neither this app nor wiping battery stats in recovery has ever affected anyone's battery life or battery indication in any way, shape, or form.
Want to know why battery drains after flashing a new rom or kernel? Hint- it has absolutely nothing to do with incorrect battery stats- totally disregarding the fact for a moment that batterystats.bin has absolutely nothing to do with battery charge indication.. After flashing a new rom, your device is actually using more battery than usual as accounts are set up and synced. Likewise, after flashing a new kernel, it takes a short amount of time for the kernel to "settle."
If you still believe the myth that battery stats need to be wiped every now and again, there's an even easier way to do it than wiping in recovery or using some snake oil app... charge your device to full or near full and then unplug it from the charger. Voila- you've just successfully wiped battery stats!

OP, stop posting nonsense. Seriously.

Strange battery behavior
It's actually odd, my battery started getting stuck at 100% like a week ago or so, after 11 hrs standby time and 30 mins screen-on time, it doesn't even drop 1%. However, it shuts down normally at 1%. I actually tried so many things to fix this, i opened the back cover and pulled the battery out, i let it run dead and charge it all the way up, but it just seems to like that 100% mark. Since it actually shuts down at 1%, i wanted to make sure it's completely dead, so i booted into recovery and oddly, with max brightness in twrp, it took about 15 mins for the device to completely shut down.
Any ideas what might fix this?

Bear in mind that you optimally do not want to discharge the battery to the point of shutdown. Doing so shortens its lifespan, and can trigger the N7 to go into a hibernation mode on order to protect the battery from permanent unrecoverable damage due to a deep discharge.

The app has nothing to do with it as the only thing it clears is the list of processes that have operated on battery since the last full or near full charge.
The only "calibration" that an end user can perform entails a complete discharge/charge cycle. This resets the flags for the battery's internal fuel gauge.

This is all the recalibration the device needs.
Naja is 99% correct. It's not the only calibration you can do (you can wipe stats), but it's the only one you should need to do.
batteryuniversity.com has a couple of good articles on the care and feeding of Li-Ion batteries. There is a lot of less than accurate info that floats around about batteries. The above site is a good way to learn the difference.

Battery Reducing Quickly?

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.
"Would this cause my battery to go down 2% in an hour without any use? "

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)

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

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.
