[Q] [HELP] Battery gremlins

I've noticed that a bunch of people are running into battery usage issues recently and I'm one of them. I'm looking for a clean cut way to get back to great battery life. There has to be some funky crap going on that can easily be cleared with some Odin flashing, but I'm not entirely sure what to do.
I achieved great battery life last time by flashing to stock ED1 (stockrootedED1-20110517.tar) then accepted the OTA for EE4. After this, my memory gets hazy. I can't remember what I did after this, but I think I flashed some version of Altered Beast via Odin. I eventually went over to GummyCharged 1.5 and had amazing battery life.
Last week I started going a bit nuts with installing themes and updating the new ROM versions, and now my phone has crappy battery life. I tried flashing various Odin packages but I'm not having any luck getting that good battery life back.
And the fact that Odin is a flaky piece of crap doesn't help. Please do not post "use Heimdall," because I wanted to get something posted for Odin users and that would ruin the point.
Thank you in advance!
EDIT: Danalo's Odin bundle had a bad download link last night so I couldn't test that out. I'm giving that a shot now to see if that clears the battery drain issue.

Whoops, I'm probably going to get bashed for not posting this in the General forum despite the fact that his is a specific issue. Sorry in advance, imnuts.
And please, do not point me to http://forum.xda-developers.com/showthread.php?t=1132726. That thread is useless.
EDIT: Proof that my battery didn't suck:

Nope. Just flashed the Odin bundle that danalo made and my battery dropped from 85%-84% while going through the initial setup.
This is crap. What the heck is going on?

I'm having the same experience. I've tried GC and Altered beast - different kernels.. every combo gives me terrible battery. I had to send my phone back to verizon so I was running stock EE4 for about a week and it was significantly better battery than any of the custom roms. I've tried wiping everything, battery life, cache, factory, even wiped my @$$ every time I changed anything and those gremlin bastards are still chugging my battery life.
I think this is a good section (development) for this post to see if anyone can actually figure out the problem, I've seen several posts claiming to fix the problem in the different development threads and none of them are legit.

Yeah, flashing the Odin bundle that danalo made did not help I don't understand what is causing the issue.
After flashing the Odin bundle, my batter y dropped from 85% to 84% while running through the setup process (log into Google, etc.). Ridiculous. Then I went outside for a smoke and checked out some web pages.
My battery is now at 67% and it has only been ~35minutes since I flashed the Odin bundle. How can a battery drop from 85% to 67% in that short of time?
Voodoo is disabled.

Well here is my solution
I just ordered this back pack looking thing from new egg, it looks like the old ghost busters proton pack but has mini usb port. it weighs 30lbs but now my charge can stay plugged in and make it through a 12 hour day

That'll do! Or this - http://forum.xda-developers.com/showpost.php?p=14685613&postcount=459
I found one of my posts where I laid out my steps to obtain EE4 radios with custom kernels/ROMs. I'm trying this now.

You really can't judge battery life until a few days after you flash something, due to battery calibration.

I can judge it if it's dropping 1% per minute.

Ive been having this issue too, if you click on my name and click on my posts, i have posted a crap ton on this issue.
the standard response I seem to get is "you flashed wrong"
this is not my first time around the block.
however, kejar31 posted an exact method to flashing and resetting battery stats. I have reset battery stats, and did the charge up thing, but never in the order he stated. so I am going to do it exactly.
refer to this post (1105) by kejar31

I will report back once this is completed.

This was happening to my phone where it would start charged at 7 am and die by 3 pm with no use at all. What i did to fix it was install the new Cwm test.tar and then install the touchwiz 4 theme. i then installed pbj kernel (non oc) and charged it to 100% and wiped battery stats. then i let it die and recharged it and wiped battery stats again. Worked like a charm. my battery can now easily run the whole day and still have 40% by 10 pm. And the touchwiz 4 theme is really nice. gets rid of the terribly ugly brown and orange theme and you are still on stock ee4. you can use debloated if you want but custom roms always destroy the battery on this phone for now. And if you wait another day, p3droid is going to release leaked gingerbread on the team blackhat app. that will surely be amazing because on my DROID X, on froyo the battery life would be good, and it would be amazing with an undervolt. But with gingerbread, i got better battery completely stock than with undervolted froyo. Gingerbread will be amazing. here is the video:

Where are you getting this information? This sounds completely false. And it's not going to calibrate from 5 hours of idle battery time to an acceptable amount.

1. Can you post a link to the CWM test.tar you're referring to?
2. Also post a link to the PBJT kernel you're referring to.
3. I was using GummyCharged after the EE4 update and had incredibly awesome battery life. I'm not exactly sure which update screwed up my battery life, but I had installed various themes and updated GC when the battery nightmares began. Since then, I've flashed various packages and have not had any luck getting back to great battery life.
4. How do you know the Gingerbread leak is coming out tomorrow?!
EDIT: I followed this post in hopes that it would clear my battery usage issue, but sadly, it did not - http://forum.xda-developers.com/showpost.php?p=14660877&postcount=1

I just followed the battery wipe instructions to a T.
I went from 98% battery to 92% battery in less than 10 min during setup and installing XDA.
This is my usage stats (tracked by me)
I was running stock EE4, no root, stock kernel.
i was getting 12 to 15 hours of battery with moderate heavy use.
I unplug my phone at 7am every day, and plug it back in at 10pm. my average battery percent at 10pm over the course of 5 days is 26%.
Using gummy, starting with 1.7 through 1.85 with the same usage, unplugging at 7am ever morning, I did not make it till 10pm without charging. not once.
I have data for 8 days using gummy, unplugging at 7am, on average I was able to make it to 1pm before getting the battery dead warning.
After reading all the posts on the "proper" flashing method, today I followed the directions exactly.
To re-cap this is what I did:
1) From a stock phone at 100% battery, I powered down the phone
2) Removed the battery
3) Removed the SD card
4) Plugged the phone into the PC, holding volume down to enter download mode
5) fired up odin 1.30
6) using odin, I pressed the PDA button, and selected "New_CWM_Recovery.tar"
7) once flashed, I removed the USB cable, replaced the battery, held "home", "volume up" and "power" to enter recovery.
8) inside recovery, i wiped user data, wiped cache, wiped davlik cache, wiped battery stats.
9) I powered down the phone, and repeated steps 7 and 8
10) I then installed ZIP "0602_charge_voodoo.zip"
11) I restarted phone and repeated steps 7 and 8
12) Installed "GummyCharged1.8.5" and booted the phone.
while typing this post (about 10 min) my phone has dropped 4% battery.
I will use the phone until the battery dies completely, I will then charge it back up to 100% and , according to every other person, this should fix my battery and the phone will run all day.
I will update shortly.

I guess I'll report my findings as well...
I received my phone yesterday and had flashed the PBJ kernel and GummyCharged before it even finished charging up for the first time. Didn't wipe battery stats or do any other battery-related tweaks. Let it finish charging last night and kept it plugged in all through the night. Got up at 7am and took it off charge at about 7:30...
It's now noon and I've got 85% left. Data connection is on (3G) with steady coverage, all other radios are off. Most of the time has been spent in my pocket or idle on my desk, but I've also downloaded/configured a few apps and used gmail and SMS. I have NoLED running but the notifications haven't had to stay on much since I'm at my work computer and the phone is sitting right next to me.
My previous phone was a Droid 2 running the Fission ROM and during a normal day's use I'd dip as low as 60% at worst... I'm guessing I might get near the bottom of the bucket with the Charge, but we'll have to see how it actually goes.
edit: 1:30pm now and at 83%...

are you using the imnuts pbjt kernel ? im starting to think this may be kernel related.
also, i was discussing this in the IRC channel, and someone told me it had to do with formatting the SD card? Im not sure what he was talking about. im going to research that further.

i am posting some of the stats I have collected this far.
this is my 4 hour comparison chart.
http://dl.dropbox.com/u/12361411/4_hr_comps.pdf
These tests were done using the same apps and same pattern of usage. in all cases, Bluetooth was off, wi-fi was on and I am consistently in a 3g coverage area with good signal.

Yeah, but I was using the PBJT kernel 1-2 weeks ago when I had insanely good battery life. So I'm not so sure that it's the kernel
I just flashed the Gingerbread leak in hopes that it'll help with poor battery life.

I'm in the same boat as you guys. I was running stock rooted with imnuts' PBJT (non overclocked) kernel and getting crazy good battery life. It was the same as it was when I was completely stock. Since messing around with custom ROMs, I've had a nosedive in battery life. I used to go to work and put my phone in airplane mode when I got there due to extremely poor cell coverage in the building and would lose at most 2% over 2-3 hrs. Now, I lose 7% or more. I really enjoy GummyCharged and I don't want to go back to stock, but I don't know what to do. Like you guys, I've tried a lot of these black magic rituals of wiping/flashing orders to clear up my battery issue, but I've had no luck.
Right now, I've at 55% battery life left after 10 hrs 40 minutes, which sounds pretty great, but my phone was in airplane mode and sitting in my pocket for 7 hrs 30 minutes of that time. Its not completely awful, but its not what I was getting before. Also, when using the phone to do something light like return a few texts via Google Voice, I can watch the battery meter count down. :\ If you guys have a method to try that you want me to be a guinea pig for, let me know.

[Q] Battery stuck at 100% | 1 hour no charger still 100% | cannot charge battery now

The Problem
As the title mentioned in the title my Battery is stuck at 100%, I've left it for an hour without the charger and it's still stuck at 100%. I plug the charger back in and the phone thinks it's fully charged so it doesn't charge.
I've turned my phone off and am awaiting instructions on a fix because if my battery goes flat I won't be able to charge it and my phone will be useless.
When it happened
I don't know when it happened exactly but I was getting S-OFF using the JUOPUNUTBEAR method as I had a H-BOOT of 1.27.0000 which revolutionary.io couldn't S-OFF.
Once I got S-OFF I installed LeeDroid ROM and then I noticed my battery was stuck at 100%.
What I've tried
Using a different battery (I have OEM and Anker)
Changing ROM to Android Revolution HD
Extra Information
While changing Roms I installed 4EXT Touch Recovery which in Recovery mode it has it's own Battery Meter, they also said the battery was full (though I didn't unplug it for long)
I have the same 100% stuck problem with Android Revolution HD, I'm starting to get worried and yes I have waited an hour without the charger connected and still have this problem.

Does it do this with all Rom? Have you tried to calibrate, possiably app might allow you to change the configuration? I'm just guessing here, hopefully you will find a fix. I've never heard of this before, this is a new one. Perhaps someone with more knowledge can help! Sorry I couldn't be of more help.

Have you tried using it heavily for 30 minutes like playing a game or something?

I experienced this issue but its only with some roms. I left my phone on overnight not charging (8pm-11am) when I last use the phone and it still said 100%.

try wiping battery stats first
use battery monitor widget or battery calibration app or from recovery(4EXT ->wipe|format->wipe battery stats )
then if it still didnt fix the issue
try another ROM or reflash the same rom...but before doing that ...
i want you to wipe everything using inbuilt 4EXT wipe feature not superwipe
(4EXT-> wipe|format ->format all partitions except sdcard)
then flash the rom
if its still fix the issue
flash an RUU (this will cleanup everything)

I wiped battery stats from 4EXT recovery which hasn't fixed this issue.
I will re-flash Android Revolution using your instructions tomorrow.
If my battery goes flat during an ROM install what's the worst that could happen, could I completely brick my phone or could I still access recovery to restore my ROM Backup, or re-install ARHD ROM from 4EXT.
If all that fails what would be a good RUU to flash? would I then have to make my phone S-OFF again?
Thanks for your time, it's much appreciated.

If the battery runs out just leave it to charge for a while. You'll still be able to get into recovery so it doesn't really matter I think

Before I seen your post I wiped batterystats.bin with the BatteryCalibration App from the android market and didn't do anything. As I explain below I got it to work with 4EXT recovery wiping battery stats, but I thought the Battery Calibration app did the same thing. In that case I think taking the battery out and in for a second time may have worked.

Actually I waited a little longer and my phone went down to 98%. I left it on overnight and now it's 63%. It looks like it's working again.
But with further checking I noticed a couple of other weird things.

If you look at my pictures above, here it says "Status: not charging (0mins)" & "Status: not charging (19mins)".
When I took them screenshots I hadn't had my phone on charge for over 10 hours. Oddly for very small intervals it's charging itself. At one stage I think I check it it was 75% then I checked again and it was 76%.
Something else that looks a bit odd is my phone temperature, in my screenshots you can see it says it's "11.9" & "11.6" degrees. It's over 14 degrees here in Australia how could my phone be colder than the temperature outside. I remember my phone used to be "26" degrees often. "11.6" dosen't seem right.
Do these two issues seem familiar to anyone. I know there not big problems but it would be nice to have them corrected.
EDIT: I decided to do a Backup in 4EXT and my phone was saying 55% battery and in 4EXT my phone says it was 62% why the difference? Could this be a problem? which one would you think is the correct one.
EDIT2: It did go down to 55% pretty quick while doing the backup, prehaps it needed time to work out battery life.
EDIT3: Now m phone battery says it's 72%, then it quickly went down to 69%. It never used to do this before I rooted. Could this case any problems, like the battery to go too flat to the point it's unrecoverable.
Sorry for all the edits and questions, I just like to understand my phone and be sure I don't break anything

Battery percentage fluctuations are common when you just change a rom.. Even after reboot if the battery percentage goes up then within few minutes the percentage goes to its actual.. The battery requires some time to settle so when you change the rom or kernel these fluctuations do happen(remember these fluctions are in numbers only the battery charge doesn't increase Actually)
Once you use a same rom for like a week or so.. The battery stats sync up with your usage.. So no worries
Also regarding the temperature it seems like the battery you have doesn't have temperature sensors (anker doesn't have sensors too so always temperature is 11C for me)
Sent from my pyramid.. Through blazing fast sonic waves

Anker does not have a proper thermistor.

Why would you even complain when you have such great battery life? That's pretty strange
Sent from my HTC Sensation using XDA

I think I have a similar problem with yours. The issue with my sensation is that it charges up to 100% and after I unplug it the LED stays lit up green until around 85%. Once it goes lower than that, the battery icon shows that its charging and the LED stays lit red but the battery percentage is decreasing and it continues to do so until around 60% remaining. Then when it gets to 59% the LED turns off then that is only the time that the time in the battery stats starts to record how long its been on battery for me. Sometimes at full charge when I start to use the phone for heavy usage such as games, the LED starts to change to red even if its around 95% and unplugged from the charger. There are times that when the LED light is red and I plug the charger to the phones USB port and not connect it to an outlet, the LED light turns off. I don't know what caused this since I just got my Sensation from another person. Still all features are working great and am able to flash ROMs normally. Kinda a flashaholic if its even called like that. No other issues other than this. I haven't tried to use a different battery since I don't have the extra cash yet. Please bear with my long post. Thanks.

This is not a problem. This is normal.
I go to work at 100% and dont use the phone much. Several hours later it still shows 100%.
Relax. Its not a bad thing. The battery is not draining rapidly and lying to you about it.
Sent from a rebel ship by storing the message in an R2 unit. (Help me, XDA. You're my only hope)

It takes a few cycles to with right. I can use my phone for up to an hour, plug it in and the light is green. No big deal, as the phone doesn't want to overcharge the battery. As so as the percentage drops, it charges. It gets better as you use it more.

Terrible battery drain with any ROM with different batteries

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.

[Q] Is it battery or ROM or Kernel issue ?

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
Sent from my HTC Sensation using XDA Premium 4 mobile app

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
but the difference is i don't have that fast drain
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.

New battery, 4V reading after 33 minutes of display... WTF

Hello!
As you may guess from the title, I just changed my battery and after having it charged fully I noticed the the voltage reading on CPUZ was 4300+V after many minutes browsing the net over LTE. Although I'm no genius in voltage and stuff, it seemed to me a little strange and I kept tracking the reading. Right now is about 40 minutes that the display is always on and the OS says 100% (I bet it ain't right :good.
Now, may I have broken the SoC while changing the battery so that the reading could be altered? May this new battery have come from the future where it can store enormous amount of charge thanks to alien technology?
HALP I don't want my phone to explode like a Note 7 :crying:
EDIT: the voltage now seems to have increased even though I did not connect it to the AC. Now I am going to sleep, hoping that I do not blow up. Wish me luck.
EDIT 2: Before going to bed I rebooted the phone. After the reboot and around an hour of screen time it has consumed about 33% of the battery (I had those low consumptions only with CyanogenOS 12 LOL). The SO now seems to be reading the battery correctly. What could it be? Still hoping not to burn down during the night... Good night!
EDIT 3: https://goo.gl/wKB4Bs

This graph shows percentage and voltage of the battery over almost 24h. At first i'm charging, then i use it normally. After many attemps like this one i noticed that the battery life is now normal, but the percentage is still f up. Maxium voltage was around 4.3V, which is fine i guess

Well readings are looks like normal but this is anormal of course. Maybe it is a new battery so it's opening state maybe you need couple cycles to make it adjusted. Is the battery original? And you done all correctly? Maybe clean flash fix it or use it until its dead and recharge while phone off to %100. Keep me updated.

Just do a full discharge-charge cycle and keep it plugged in overnight with a powerful 2A charger. Sounds like your battery needs to recalibrate and that's what this does.

I think it's common bro. No need to worry
I always have that kind of discharge voltage

Thank you all for answering Now let's have an update:

Maybe the voltages are but the percentage is crazy tho!
Now i have few updates:
- if i fully charge the phone, it will keep the reading at 100% until i reboot the phone
- the OS is able to keep track of the consumption until the battery percentage goes below 100%
- rebooting the phone changes the percentage reading always (LOL)
- i did not notice any real increase of the battery life compared to the previous stock battery
Here 3 screens i've done, the first two are from yesterday after the first full charge, the last one has been shot right now. and the phone got detached from charging around 11:00.
The mystery deepens....
EDIT: Just rebooted, 70% battery displayed from 100% rapidly decreasing

Still sounds very strange. I suggest you to go FULLY stock(like out of the box stock) and then use it with stock firmware for a time. Maybe it helps..

I hate stock ROM, i'd rather replace back the stock battery instead. Putting aside personal preferences on ROMs, how can changing ROM alter the reading of the battery? I mean, it does depend only on the voltmeter reading, and that's HW. Are there different ways to interpret the voltage reading? If so, i'd like to see some examples. Just curiosity

yes it is up to voltmeter but voltremeter sends its readings TO the software and i think there is a somekind of cache. And when you unplugged the old battery and replace the new one it might corrupted the reading. But on the other hand replaceable battery phones can do this switch w/o problem. Maybe there is something special or additional thing going on there. And not flashing any other rom but going back fully stock might be the right solution for you because it flashes and deletes everything. Resets everything. After that reset you might as well flash twrp again and flash custom rom again. But maybe theese all just an theory and going back to stock will not help. Maybe only faulty thing is battery but you wont lose anything with trying. As long as you backup your data

I went back to stock (still unlocked bootloader tho) and fully discharged the device then fully charged. Now, at 100% reading i unplugged the phone and started an AnTuTu benchmark to see what happens. Again it was still showing 100% after 2 full tests (the device was crazy hot on the camera, i know it's normal) so i rebooted. After the first reboot was still 100%, after a second reboot it showed 89%. Let's keep testing... Any idea? @zaoms

Hmmm, if you even went back to stock and that not helped i am really thinking your battery is faulty. Have you ever watched oneplus one battery replacement videos on youtube to see if you really done it properly?

Actually now, around 50%, it started behaving normally I think that the stock "needed time" to recalibrate. Rebooting now seems to not giving any problem and the discharge time seems to be reasonable. Now i am flashing back Sultan, let's hope!
By the way i followed the ifixt guide here

well great then! i assume something has been ressetted when you went back to stock and now it collecting data from your battery or something. And put this things together it starts to behaving normally. I hope it continues like that:good:

It's because of sultan's battery driver. He has changed some voltage thingy (AICL, remember @zaoms). But I'd suggest you to flash another ROM like LineageOS to check if it's the same as stock COS in terms of battery "calibration". Let me know what happens.

The mistery deepens even moar... I'll try as soon as i can but i need a stable ROM right now because i have an exam tomorrow and i need to prepare my cheating table for phone and weareable xD
I'll try tomorrow tho, thank you guys ^^

After few days of testing I'm back!
I'm using the stock rom for a while now and unfortunately the battery has not "calibrated" or whatsoever. Nevertheless i've found a pattern in the battery readings fluctuations. Here's the roll:
1) battery completely discharged
2) charge while turned off until it says 100%
3) turn on the phone, it will now say 88-92%, let it charge until 100%
4) reboot and hope it still says 100%, otherwise go back to point 3
5) use the phone until it powers off by itself
6) turn it back on and it will say something like 60-70% remained battery
7) use the phone until it powers off by it self
8) turn it back on and it will say something like 10-70% remained battery or be really discharged
- if still charged use it until it's really discharged
That's how a battery cycle goes right now with stock OS and unlocked bootloader (just fyi). Any idea of the reason behind this abnormal behavior?
Curiously, when try to turn on the phone in the end it vibrates, does not turn on and does not shows the low battery warning, why?
I'd like to point out that sometimes the reading of the voltage of the battery increases for a moment then goes back to normality while discharging (is this magic?).

Update: i was charging the phone while turned off from 0% and it showed to me the low battery sign., after a while it started charging apparently correctly.
Now after 1h the phone was showing 100%, i detached from the AC then connected again and it showed 100% but started to decrease the charge until 68% then again started charging. LOL

Update: seems like i've get what's not working!
What is broken right now is the charging: the phone is not able to understand how to charge the battery fully. Right now i've found a workround:
- turn off the phone and connect to charge
- wait until you see 100%
- unplug, wait few seconds to let it turn off
- plug again and watch it going backward from 100% to the real percentage
- repeat until it will not fall back
Now it gets really charged up to 100%. How can i automate this?

I saw your link on the ebay feedback profile of the seller. I have the exact same problem and am pretty sure the batteries are just low quality and faulty. Its the second battery this happens. Exactly the same thing. The first time I got such a battery I fully discharged the phone up to a point it wouldn't even get to the boot logo, and the battery died. It wouldn't charge at all and that was the end of it. I don't believe there is any way to fix this but to buy another battery and pray.
