Hello,
I know such tread were posted several time before and i read all of them but i did not find any solutions to my problem. My battery drain is really bad with stock battery, Anker battery, Mugen and others.
Battery darins like 1% per minute or 5 minutes even if Data,Wifi,Sync are off and i the phone not used at all.
So far i have tried the following:
1) Installing different ROMs (I even tried installing the ROMs and not adding any new applications and not modifying any settings to see if it is a problem with an app i have or ROM). So i flash a ROM and leave it as it is, without isntalling anything, but battery drain is still very bad
2) I have tried calibrating (charging 100% and wiping stats) several times
3) I have tried different batteries including Mugen and Anker.
4) I tried those all together several times..
5) I have tried better Battery stats and battery widget to check whats wrong but did not find anything unusual.
6) i have tired to charge my battery longer than ususal (to make sure it is 100%)
battery Usage says 89% of battery is used by Android OS
I suspect this might be a hardware problem but how can i check this? and is it possible to fix? Maybe i should go to recovery and check how long does it take for the battery to go from 100% to say 5% ? but i need some figures to compare with.
so my questions are:
A) Did anyone have similar problems? if yes were you able to fix ?
B) How can i check if there is a hardware problem with my battery connection or something else that might cause battery drain
C) Can anyone let me know how long does it take for the battery to go from 100% to 5% (or 10% or 20%) if the phone is all the time in recovery mode?
D) Can the charger be the problem? I am using stadard Sensation charger..
Any help and advice will be highly appreciated
Thank you
I don't know how long it takes for the battery to go from 100 to 5% in recovery but I've forgotten my phone at home and not plugged in the charger and it has lasted all day.
Do you just test right after the installation of a rom? My battery usually drains fast after I flash a new rom but I'll let it go from full to dead then charge it overnight and the battery will last way longer after that charge.

do you use Titanium Backup? if so, find the app called "Google Backup Transport" and back it up real quick. then delete it, reboot into recovery and wipe dalvik + cache. then reboot the phone to see if that helps.(wait 2-3 days) back on the MT4G there was an issue where that app caused the Android OS to use a lot of the battery, might work here too in your case.
Hello,
I am still having the problem with my battery drain. I have tried finding Google Backup in Titanium Backup but it was not listed.
However, checking the battery use Android OS takes more that 85%...
I have installed another ROM.
Android OS now disappeared compltely. and it is Cell Standby that is eating all the juice now... But the battery drain is the same. I think the battary Usage indicator does not give any usefull information on what is using the battery..
But the bettery is getting quite warm... and continues to discharge. I just charged to 100% and went asleep. When I woke up next day after 8 hours I onli had 20% of battery remained... WiFi, Data, GPS were switched off.

what rom do you have installed now? if your problems keeps happening after switching roms, theres probably 1 of 2 problems. Bad battery (Im canceling this out because you said youve used multiple batteries) or a rogue app that is running in the background, killing your battery
also, have you tried formatting your SD card? save all the important stuff and try formatting it, then transfer all the data you saved back to the card
You should try changing your charger. Once I bought a new charger from ebay and I had a lot of probs, the phone took forever to charge, it got hot when charging, the battery would hold less charge.
I suggest you try deleting system,cache,userdata,boot with fastboot commander.Here The instructions to use it:
-download tool
-unpack zip and click on .exe application (is a stand alone app, so you have to click and confirm installation, that's all!)
-open tool
-put DHD in "Fastboot Mode"
-plug it to your pc usb
-Wait for "print of device succesfull"--(if fails, check your sdk driver)
-here you go to "misc"
-select: erase partitions (system,cache,userdata,boot) Don't select recovery
-click on "Erase chosen partition"--
-Done
-manually reboot dhd to recovery
-don't care about error message like E:/can't found recovery log" or something like this.
(It's just recovery wich telling you that partitions are not mounted!)
-So wipe data factory reset to re-mount partitions, otherwise you can't flash anything!
-now flash your rom
this way you are sure that your phone is completely wiped! And when I said completely I mean COMPLETELY!! (except for recovery)
This tool is very useful to solves strange issues that a normal wipe cannot solve! Sometimes happen
Last but not least you could try updating your recovery to the latest version.
Hope you solve your problems:good:
Hello,
1) Yes i tried 3-4 different batteries. Is it possible they all are damaged? By say damaged charger?
2) As for charger, will USB charger work fine (connected to PC) ? Currently I am using the wall charger, but i do not have a sapre one to try.
3) I will try to wipe everything using the tool provided. Thank you.....
I think I already have latest recovery.
P.S currently I am swothching between MIUI roms, but i had ARHD and other roms before that with smae problem...
Do you spend a lot of time in an area with bad cell reception? If so it will spend a lot of battery constantly trying to ping a cell tower.

If you want you can try using my combination of rom/kernel, you can find them in my signature, I myself had battery problems, but with my Anker and this configuration I get 24 hours of medium usage. Yes the USB charger will do the job and just check if your wall charger has the right output voltage (5v).
Another thing you could do is download this app from Playstore Battery Monitor Widget. It shows the current mA drain/charge.If you see that battery drain is strangely high (example 200mA in standby than your problem isn't the battery/charger. I get a drainage of 3-10mA in standby, which is pretty good. Good luck finding the couprit:good:
Thank you all for your advice!
1) as for ROM i do not think any other ROM/Kernel is going to make a difference. I tried to many of them by now. And I do not think ANY rom is so bad to drain 10-15% per hour while phone is not in use
2) i tried different SD cards and tried pulling out the SD completely, so it should not be the case...
3) I am in good reception area. In fact the phone used to work just fine in the same area when i just bought it... but then something went wrong (cannot find what)
4) If it is an application - than should be something inbuilt in the ROM. because I have tried installin ROM and keeping it clean without installing anything at all. not even changing settings... but the problem was still there...
and 5) I am using Battery Monitor Widget and it is between -35mA and -75mA.
Seems too much but I still cannot find the cause..
IT seems that i also have this issue!!!
using 2 sense 4 roms and my battery usage never ever come down to -40mA !!!!!!!!!!!!!!!!!!!!!
i can not find culprit yet...
really annoying
I have learned a lot about my device since i bought it. The only thing I cannot figure out is the details about the Radio, and which one is the best for me. Can it be that the problems with battery are caused by radio?
What are three best radios to use with JB MIUI Member's choice and othe MIUI Roms?
Thanks
It seems like it was Radio after all.
I have checked my version and it was displayed as N/A instead of 11.68
so i reinstalled the radio and it seems like the problem is solved. at least today i have no problems. I will see if it will be fine tommorow and thereafter..

hmm thats weird? has your data connection gotten any better after changing radios, or is it still the same? good to hear you fixed the battery drain
Hello,
not the connection 3g, data. wi-fi works just as it used to work - just fine. The only thing that changed is that the battery does not die within few hours.
in standby - i have now easily more than 24 hours....
It seems liek the problem is back again. I did not isntall anything new or changed any settings. but suddenly i woke up with 40% of battery on my phone istead of 100%..
it really start to irritate me. There is nothin i mgiht have done to cause this. But the phone is noticabely warmer when it eats the battery for no reason....
Android OS is responsible for 83% of battery drain. While battery life was OK it only had 2-3%...
PS
Today i lost 60% of battery (from 100% to 40%) while sleeping and my phone not used.

Try installing CPU Spy from Play Store and see if the phone is in deep sleep while not being used. Although this tool doesn't give a lot of information, but at least the 1st thing we can see from this tool is whether the CPU is put into deep sleep while the phone is sleeping. Losing 60% while sleeping is very likely that the CPU didn't go into deep sleep state. So this tool should give you some indication. If the CPU ever goes into deep sleep, you'll see the Deep Sleep entry below 192Mhz.
Hello, i'm a newbie to xda developers... I had some problems with my Sensation... I am really a newb to those stuff since i never rooted a phone... The problem with my phone is that the battery doesn't slowly drain... I let it to charge for like 5 hours to get to full 100% and then from 100% it goes to 60% in like 10-20 minutes while i use it ... Other times the battery shows to have more power and other times it straightly goes to 40% from 100%... It drains so quickly i can't even go outside with my phone since its battery gets empty... Sometimes, even if the phone is 60% it randomly shuts down and have to restart it for like 5 times to get it work for at least 10 minutes. Might it be the battery? I tried going to recovery mode but i get the red triangle with an exclamation sign in it... Any reply is appreciated, thanks!
Maybe your battery is rubbish and you should just buy another one.
Although is one thing you should try first, recalibrate your battery.
What all these methods amount to is how to teach your phone about battery performance. Calibration is about enabling your phone to provide accurate estimates of remaining battery charge and will not, in and of itself extend the usage you get on a single charge (though it may possibly prevent the phone going into power save modes prematurely, wrongly believing the battery to be lower on power than it is).
The phone stores information about the battery in a file called batterystats.bin which sits in /data/system. Normally you won't have direct access to that file, but you could find it with an app such as root explorer, which allows complete access to the phone's file system.
When you install a new ROM, or a new battery, or perhaps periodically as the battery ages and performs differently, you need to get a new set of battery performance statistics.
By charging the phone to 100% you are starting at the known maximum for the battery. At this point, the batterystats.bin file needs to be deleted, which forces the phone to recreate the file from scratch, using the information it is about to collect. It doesn't matter what method you use, battery calibration app, or from within recovery - they all do the same thing and delete this file.
The phone is then allowed to drain fully. This gives the other end of the scale, the known minimum. The phone then has then experienced the full charge/discharge cycle of the battery and stored that performance information in a new version of the batterystats.bin file.
Now that the information has been saved, the phone will (hopefully) be able to provide accurate estimates of the battery charge level, regardless of how much of the battery charge you use before reconnecting the charger.
If you don't have root access you can download an app from the market called "Battery Calibration". It does the same thing, deletes the batterystats.bin.

Thank you for your time. You explained really well and i appreciate that... So, to use the calibration apps i need to have root access... should i search a tutorial on that or is there one on the forums? If the calibration can't fix it, should i get another battery? Thank you again! Maybe i should try to buy a new battery first... is rooting safe? can i get back to my old firmware?

Well, yes I guess you should root your phone first, but I'm not sure
A guide on how to root your Sensation can be found here .You should only do the steps 1-3.
If you don't want to root there is another method somebody wrote (I haven't tested it personally)
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds minimum
6. Put back the battery on the right side.
7. Turn on the phone.
Than you should be OK:good:
If you get the same result after "battery calibration" I suggest you buy another battery.
Hit THANKS if I helped you
Hello, i have two more question related to this thread... Is there a way to calibrate my battery without root access? And will buying a new battery surely fix my problem? Thanks again!
You might be able to get a calibration application in the playstore. However most I've seen require root access. But look, they're might be some without root requirement. As for your second question. Nothing is ever 100% guarantee that it will solve the issue. These are suggestions based on the information you provided regarding your issue . How can anyone be 100% certain that will solve your issue. It's defiantly a possibility it will solve the problem but no, for 100% certainty, I don't think anyone can say that. It's defiantly worth a try ! Then you can see if getting the battery solved the problem. I hope it does fix your issue and wish you the best .like I said, no one can be 100% sure but it's defiantly worth trying!Sent from my HTC Sensation 4G using xda premium
Everything said in this topic is PURE NONSENSE. It was even featured on the front page that wiping the battery stats DOES NOT DO ANYTHING. See this article for more information > http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The only thing you CAN do is charge your battery to 100%, and let it drain to 0%.
Aparently, after i cleaned my battery contacts it DOESNT jump to random values... drains continously.. SO i think the problem is fixed... atleast for a while! I'm new using a smartphone and the battery is a little 2 weak as i was used to my other non-smartphones... I think that's the battery life a 1520AMH can offer me on a sensation! The uptime for it was 6 hours from 100%... thats really weak ( i used the web and games).
I have a serious problem 2days back I flashed sense build 4 and by battery diacharged within 4hrs I thought its battery problem and purchased new battery and again it discharged in 4hrs only Soviet flashed cm10 betav3.2 and even thn it lasted only 5.5hrs today I flashed cm9 beta11 with kernel 2.... and I lost 35% in 100 min is this normal oR mobile is having any problem help please

Heavy battery discharge + unable to charge battery till 100%, stuck at 83%... Done everything possible.. Using FlyROM v2 Kernel 3.0..
vishuhtc- You can try installing "better battery stats"(check out xda), or "GSam battery monitor", you will see what is killing it, if you don't get your answer with this apps check this thread http://forum.xda-developers.com/showthread.php?t=2093542 . Also if you are using super wipe, to flash roms, try flashing without it, or with it, but manually delete bootloader data, cos it doesn't do it automatikly
khanjan2khan- check out with the second app what voltage gets to your battery, it should be something like 4.000V or a little bit more, if it goes to that, you should also calibrate it or just delete battery stats from recovery, if it doesn't get to that............. try with another charger, or with a service center.

Ok on start I am sorry guys for my language. I am in UK only one year so I need to learn a lot
10 min a go I back from SSC because I have problems with battery/ charging and foulty speaker
Italian Job 1.0.0 - big battery drain and battery go dawn after restart by 30-60%!
XXMC8 - no battery drain but battery go dawn after restart by 30-60%!
Stock UK GB XXLK7 -no battery drain but battery go dawn after restart by 30-60%!
So I bought new original samsung battery 1500mAh - no changes
So I bought batttery 3500mAh with special cover - no vissible battery drain, this battery can handle my phone by ~ 20 hours of playing AVI movie, 720p in loop in MX Player so very good score but battery go dawn after restart by 30-60%!
All battery was tested in my Ace 2 and in my girlfriend Ace 2 (she have fully working phone with no problems) and she have good scores on all batteries but best is on 3500mAh with special cover ( above x2 than standard)
So i went to SSC and they: (stock GB, 0 flash counters)
- take my phone without documents on free guarantees (only box)
- I must come back for that phone in this friday
This above is for + but:
- they **** that work because I have in my ducuments copy a lot of bugs! (street , town)
- they checked my speaker in noisy room (it did not take nearly as booming)
- for those guys after restart when phone loses 30% battery power is normal!
So I go after tomorrow for my phone and we will see ( They will make updates to JB! and they change speaker/ charging module)
Photo for proof attached
If they dont repair my phone I do not buy samsung phone NEVER AGAIN!
EDIT: 3 hours waiting for a response about taking my phone!
EDIT 2: that 3500mAh battery must be loaded 8 hours to get 100% form 0%. (standard charger )
I really want to know what the whole battery dropping after restart thing is about, forever happening to me and sometimes the battery completely dies. It was the same on my original Ace S5830 I got a few years ago.
If you find out, please tell! haha.
After receiving the reply I upload it here
Have nfc version and ni problems with battery with much using and sometimes little bit playing i rech two days
I dont have problem with battery (any) but with phone hardware
I must agree with you guys regarding battery drain. It's suspicios and I am also aware of a fast battery drain from 100% to 65% in just a couple of hours, or very fast after a restart.
Maybe this is the way android should work. I was thinking there was a problem with my phone, but seeing similar behaviour with yours, it must be something related to the android system.
I'm on JB me1 and i haven't this battery dran problem. After the night i just lose 3-7% battery
When I have 100% and I off my phone and turn on battery go down to 50-60% immediately in one secund! It must by hardware foult...this is not normaly working android, for me

I thought that is not really a battery draining. But it just about battery calibrating. Your phone need to calibrate the battery. Thats the problem.

its normal to see 99% when unplugging from charger, 3%-10%(Max) drop on rebooting. Battery is usually inaccurate after charging, what I do is plug it in then reboot. then it displays the right value after unplugging, usually my battery status is really inaccurate but it returns to normal afterwards (it'll show charging icon even when unplugged and charge to 100 then stops and returns to real level). I don't believe in this calibrations and have found enough proof its useless, I think most xda users agree too. Try searching some threads.

If someone want to know how good is 3500mAh battery please go to my battery thread in general section.
Hi,
My phone is almost not charging full or it doesn't show as such.
This is detailed breakup of my issue :
I put phone at charging exactly at 2pm at 2%
3pm it was at 36%
4pm it was 54%
5pm it was at 64%
6pm it was at 73%
7pm it was at 82%
7:30pm it was at 84%
after this I removed phone from charging and rebooted it. Surprisingly it showed 100%.
Battery doesn't last more than 12hrs no matter what I do. I am using Greenify too.
BT, GPS, Auto-Sync, 3G, etc all are off. WiFi On 24hrs.
Screen-off battery drain is also around 8-9% per hour.
Can I do/try something on software side before I order a new battery ?
Right now I am on Carbon ROM (20131008) with stock kernel, 1512, Ondemand, SIO, No OC. Its same on every ROM I tried except seemingly on ARHD 7.3 (used it less than 24hrs. Its rock solid and smooth.)
I would greatly appreciate any help/advice !
I also has this issue still looking for the solution

the battery misreading while charging is a common htc's fault after rooting and there is no solution yet
i have the same thing while charging my device

how old is your battery?
did you try a different battery?
make sure it fits correctly to the pins
Battery is just 1yr old. Yup I checked the pins. They are correctly fit.

this is a rom issue i think as this has also happened to many people and and this happens after many days on a single rom (and u make the rom unstable)
the solution is simple just backup ur data and full wipe and flash rom again and u will be good to do for next many days (if u keep the rom stable)
I flash ROM almost every alternative day and I always do Full-Wipe

Battery Kernel issue
I am new to xda. I actually flashed a new rom after that phone doesn't charge after switching off. Could it be a kernel issue or the rom's issue. I have a Canvas HD. And sorry if this is not the place to ask the question. I couldn't find any other thread related to this. Please help.
Similar issue here. My charging often stops at about 80%, but after a reboot the battery's full charged.
My battery also gets drained very fast, but it's about 2,5 years old so that's probably the problem.
With the CPU clock speed @1,5GHz and the GPU @266MHz i get about 15h +/-2h of battery life.
I keep battery saving ON most of the time. Bluetooth, GPS, 3G etc all OFF. WiFi ON for about 1-2h per day (if i would keep it on longer, my phone would be dead in 4-5h).
I'm using ViperS 5.2.1 right now (full wiped before install). I got the same experience on ARHD and previous ViperS versions.
Tested the charger - it's fine.
I was wondering if anybody else got an old battery like mine and how long does it last on full charge
Hi guys,
I have a HTC Sensation XE that i bought three days ago (second hand) and i have the same problem with the battery % not reading correctly.
Now this is what i observed:
- the charging is very slow - from 20% to 40% in 2-3 hours
- after 2-3 hours of charging if i reboot the phone the charging LED turns green and the battery reading says 100%.
(i tested to see if actually it got charged to 100% and it did, i turned everything on, watched a HD movie, played some games and after 5-6 hours of playing with it i still had 50%)
- tested the battery to see how fast it drains from 10% to shut down and it went on at full brightness and everything on for about an hour and something so this means there might not be any problems with the battery
- so the reading is wrong because the battery is charged after a few hours.
- i did a test to see if the same thing happens when the phone is off and i left it to charge for 2-3 hours and when i got back the charging LED was still orange. When i started the phone the LED went off and back on as green. The battery was 100% charged.
- If the same behavior happens in off mode it means it's not a ROM problem (by the way from what i know the phone is stock, the guy never did the rooting.....that's what he told me - can't know for sure).
- from my electronics background it seems the phone updates the battery information sometime at boottime. When charging, the software keeps the charging LED on because it's supposed to charge due to incorrect data but the hardware charging controller drops the charge current because the the battery is full. So this can be an incorrect sensor reading by the software or an incorrect feedback given by the hardware controller.
So what do you think, what can cause this.
Should i try rooting the device?
And i tried factory reset from android and factory reset from bootloader and the problem is still there.
Ok so i did the following:
- unlock the bootloader
- flashed CWM
- installed superuser
- wipe battery stats
- wipe device
- calibrate battery with an application from market
The problem is still there.
I figured that when in bootloader first thing you can read is the S-ON/S-OFF. Before doing the unlock it was "LOCKED" and after "UNLOCKED".
I did a relock and the status changed to "RELOCKED" so this means the guy that had the phone before me didn't root which again means the theory that says this problem occurs when the user tries to root the device is not true because it seems the behavior is observed on an unrooted device.
I will dig deeper maybe i find more ideas on what i can do.
I'm running out of software options so this is pointing at something hardware.
I'll get back with updates when i find something else.

probably it is htc's bug
the same happened to me after rooting the device
For now I will try to make some full cycles of the battery and see if anything changes. I usually use the phone at work and by the time I get home it's almost empty. Plug to charger and till morning it's full with a green light. I will have to monitor the charging times and get back with results.
Sent from my HTC Sensation XE with Beats Audio Z715e using XDA Free mobile app
Well i did some full charging cycles and nothing changed, still the same long charge time(read by the phone) and with restart it bounces to 100%.
I had the original Android 4.0.3 with Htc Sense 3.6 at the time. Got 4EXT recovery and an 4.0.4 rom with Htc Sense 4.1. Did a full wipe and battery stats , installed the new 4.0.4 rom but the problem persists.
At this point i think the battery is the problem so the next thing to do is to change it. I will get back after i change it, hopefully sometime in november.
After a long time I managed to change the battery and after a few tests it seems the problem is still there. The time on battery improved as I expected but everything else is the same which means it's something hardware defective in the phone. Also did some tests with android 5.1 and the same results. Meantime I sold the phone and got a Samsung Galaxy S3 Neo. Hope this research gives some answers to someone at some point. Cheers.
