[Q] Is it battery or ROM or Kernel issue ? - HTC Sensation

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
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

How to decide which one
Are there any Battery benchmarking app that could tell me if I need a new one ?

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.

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.

Huge Battery Drain

Hi,
I am on a rooted stock rom DDLF2. Couple of weeks i am observing high battery drain though none of the apps are running. I dont put any fancy live wall papers or widgets. I have stopped all the background apps like google play, maps etc and Background data unchecked. I always us GSM only and do not use any wifi or data network. Screen brightness is at around 15%. I use the phone very less hardly get around 5 to 6 calls in a day lasting 1 or 2 mins per call. If i charge the phone fully to 100%, after 8 to 9 hours the battery is coming down to 30%. After it comes down to 15% the lock screen shows it is charging with the percent symbol even though it is not connected to the charger.
I tried resetting the phone, cleared the dalvik cache and the cache partition but no use. I suspect this is a software bug.
Has anybody faced similar problem? Any solution would be much helpful.
I am also facing the same problem.. can anybody plz help??

Have u tried clearing battery stats..?
Do it once. then charge your phone to 100%.. allow it to discharge it to 20%..
Again repeat the cycle for 3-4 times..
this should solve the problem hopefully..

Yes i already tried it. Cleared the battery stats. But did not solve the problem. Surprisingly the moment battery charge drops to 15% it starts showing the line "Charging (15%)" on the lock screen even the charger is not connected to the phone. Not sure what is wrong.
So i am thinking of downgrading the version. Can anybody suggest me any good stable stock rom which can be used for India (since i am in India) particularly with good battery life.

try putting some other Kernel, may be BAM kernel it might help!
U might want to check if your battery is dead.

Even i was feeling that phone's battery is dead, but trust me, I reverted back to DDKP3, and installed BAM kernel .. I find battery backup much improved, I have kept GPRS on for 5 hours now ..11% battery drained. On the LF2 ( for india without BAM ) and on the ICS drain was huge.. like in 6 hours i have seen drain more than 45%
I have even bought new battery also.. but testing on Old battery only.. You can try combo of DDKP3+ BAM or DDKP3+titanium!.
Update
It's 8 hours 11 mins, GPRS on since phone was charged to 100%, battery is drained to 86% ( 14% drained) Display On for 7 mins 21 seconds!
It seems like my old battery is still well and can work!

Also i need two things for the downgrade;
1) Any posts or links which describes the procedure of downgrading in detail
2) Links on how to flash the other kernels like BAM etc and reverting back to stock if needed.

[Q] battery miscalibration, please help!

Howdy folks. I have a major problem with my t769, and was hoping someone could help me figure it out. This problem began quite some time ago and has gotten worse. My battery stopped accepting a full charge (according to the meter.)
I had been running PA (racing port) for quite a while without a problem. The problem may have cropped up due to charging the phone while off at some point. When the problem first appeared, it would only charge up to 98%. I chalked it up to the fact that some phones apparantly don't trickle charge (for battery longevity?). Then the phone would only get to ~90%, then 83%... etc.
I have tried all three kernels available to us, nothing changes. Tried several different basebands. Tried reinstalling PA, no dice. Tried changing roms. Currently on Provision rom. The battery will not charge beyond 48 percent.
My issue does not appear to be a faulty battery; I recently purchased a couple new batteries and they do the same thing. Even after charging with an external charger - the phone still misreports the battery capacity. This has the effect of reaching a battery level of 0% (according to the meter) long before the actual battery capacity is exhausted. Further to that end, the android battery stats are never automatically wiped since the phone's battery meter never actually reaches 100%. The android battery stats page currently shows 4days on battery. I suppose this is because I last manually wiped the battery stats or pulled the battery 4 days ago.
Some more odd tidbits...
When the phone's battery meter reports 0%, the phone will automatically shut off ONLY if the display is ON. If the phone reaches the 0% mark while the display is OFF, it will continue to run and sometimes readjust the battery meter in 4-5% increments. i.e. if I turn off the screen when it hits 1%, and turn back on the screen some time later and the meter will report 4%. Other times it seems it will not readjust the meter while the screen is off and will remain at 1%. When the phone reports 1%, the battery is still outputting at least 3.5v. From what I understand, most 3.7v lithium ion batteries have an approximate safe operating range of between 3.2v-4.2v.
Really odd:
It seems that once the battery is pulled, the meter will revert to 0% once the phone is booted regardless of what the meter showed before the battery pull. I have not done this in the last couple days but it has happened several times and appears to be a repeatable issue.
All of my problems could logically be caused by a battery miscalibration, save the last point.
I have tried several calibration apps in the market that don't seem to do anything. I recently stumbled on this huge thread:
http://forum.xda-developers.com/showthread.php?t=765609
I have not read through all 200+ pages but it seems this has worked for many people. Unfortunately, I've been unable to get it to report values with the lightningX2 or CM10 kernels though. It states that the CM kernel should be supported, so I don't understand why it doesn't want to spit out values.
Any help would be greatly appreciated. I've grown quite attached to this phone and would like to continue using it!
Charge your phone overnight. Reboot to recovery (leave the phone plugged in). In cwm navigate to the advanced menu. Then in that menu wipe battery stats. Then let your battery drain down as much as possible before charging it again.
That should fix it.

Many thanks for the reply. I'm currently using TWRP and I dont believe there is a section to wipe the battery stats.
I have removed the batterystats bin manually once android has booted both when the battery is in a near-dead state and in a near-full state and neither seemed to change the meter level. Perhaps I will see a different result by removing this file through recovery before Android boots?
I may install CWM to give this a shot soon but from what I understand, and please correct me if I am mistaken, the removal of this file has no bearing on the actual battery calibration. It was said that this file only affects what is displayed in the android battery stats page. There does appear to be a lot of confusion and controversy across the forums regarding whether or not this file is indeed responsible for actual calibration between true battery capacity and the state of the battery meter.
Not sure if this is important but when charging the phone (while turned off) the bootloader charging animation seems to report a value that is consistant with what the booted meter reports. (i.e. the animation will show ~50% battery left when the meter inside android will report 48%)

Just out of curiosity, does this happen across all roms? Does it do it for stock as well? Maybe return to stock and check? I gave up on TWRP not because I didn't like the recovery, but it seemed to be... off... somehow... The 2.4 wouldn't restore backups (and would randomly reboot), and the 2.3.3 wouldn't reboot when plugged in (it would just power off). I also had some issues with my sd card with one of them (2.3.3 I think but not sure) on one of the JB roms and I lost all of my data. After going back to CWM 5.5.0.4 I haven't had any issues.
Both TWRP versions are built on the default CM10 kernel (correct me if I'm wrong here). I went back to stock about 2 weeks ago and am getting 4-5 days on battery life (light usage) where on ANY JB kernel the most I could get was a day and a half. Perhaps there's something missing/wrong with the JB kernel, and as such, TWRP isn't working properly because of it.
Perhaps the battery isn't getting read properly... have you tried cleaning the contacts with iso alcohol?
Sorry I couldn't be more help...:crying:
It happens for the two JB roms I have tried. I've not tried to return to stock yet but if you are getting 4-5 days of light usage that is incentive enough for me to give it a whirl! I never was able to squeeze more than about a day and a half out of a JB rom on my blaze either, even before these battery problems cropped up. I started using TWRP on my last phone mainly due to the fact that it can compress the backups but I've also become more accustomed it's UI. I think I'm currently using 2.4, but I vaguely remember both the SD issue and the power off instead of reboot issue you describe with the previous rev.
I can't speak to if the recoveries are built from CM. Now that you mention it, both JB roms that I have tried on the blaze show higher than normal battery usage by media and android system processes. Are you running a complete stock ICS or GB rom, or is it some debloated one? Can you tell me which one it is?
I've cleaned both the internal battery connector and micro usb connector to no avail. You have been a great deal of help, thanks again!
One other quick Q... After returning to stock, do you still have the black and white colored (powered off) charge animation? Ever since I rooted this thing, the power off charge animation starts up with the stock color (green filled battery) but quick flashes off and changes to the black and white one. Perhaps this is part of my problem, remanants of the stock bootloader mixed with the rooted one?

I'm running stock rooted uvmb1 (ics), which I've debloated and customized a bit (nothing special). Stock roms have the stock battery charging animation.
The battery drain is just one of those things I can't fully explain, as I have a few other devices running CM10 or 10.1 and they have great standby/light usage battery life

[Q] help? Batterry precentage

Hi Guys, i'm noob, i wana ask about my htc sensation, after 2 year i'm using it, today i found
when battery charging (htc Senstaion) dismiss displaying percentage of battery after i restarting while charging.
****battery charging ------> Battery percentage displaying 60% then i restarting the phone while this situation
and then when phone finish restarting and ready to use battery precentage displaying 100%(full)
is it normal?
sorry my english bad
Boot into recovery and wipe battery stats.
Sent from my HTCSensation using XDA Premium 4 mobile app
if not all many users(including me) have this situation
it is a htc's common issue after rooting the device
there is no a solution yet
it is just a percentage misreading
by the way i don't know if wipe battery stats will help

probably it stops
i am not sure about that
edit: the point is the battery is increasing its percentage slower when it passes 60%-70%
but it charges the same
so if you reboot the device then it jumps at 90% or full charge

Is it known what causes this?
Someone above said "it is a htc's common issue after rooting". Is there any source on that? For all I know, percentage of charge of battery is determined by a combination of output voltage and amps, preferably referenced by a table taking battery age into account (correct me if I'm wrong though).
Rooting the device should not be an issue, unless HTC did something in their rom to detect this and let the battery percentage be wrong. Then again, most of us aren't on the stock rom. To be on another rom, the bootloader needs to be unlocked. Did HTC do something that unlocking the bootloader makes voltage/discharge readings unreliable? I doubt that...
I'm interested in this because I unlocked and flashed a Sensation XE for a friend of mine (SultanXDA's KitKat rom), but the battery discharges very, very fast, without an obvious cause. So I wonder whether it could be the battery is not fully charged and/or the phone decides it's empty to early.
"it is a htc's common issue after rooting"<- i said that
it was a source but i can't find it now
also i don't know if htc did something with unlocking the bootloader by purpose
if you flashed the rom recently don't judge the battery too early
give it 4-5 cyrcle charges until it settles down then see how it goes

I have exactly this problem.
It sounds like the same ROM, Saltan kit kat. I am using the latest kernal 3.4, having tried two kernals I get the same results. For example I charged the phone to full, and after 2 hours of use I'm down to 55%, WiFi on and browsing, gmail synced but not much else, screen brightness turned down etc.
I only flashed a couple days ago, will it improve massively over the next few days?
The phone was giving a days charge easily before flashing.
I am also noticing a message saying 'unfortunately process com.android.phone has stopped working' (or similar). When this happens and I click OK I notice the signal disappears for a few seconds before coming back. Could this be the cause of the problem?
Could it be he ROM?
I'm new to all this but managed to unlock, root, flash recovery, and flash the ROM thanks to the brilliant guides on XDA. Any help with the above would be appreciated.

i am facing the same problem , rather my problem is goes much further .
iam on stock ROM and not rooted my sensation. my device often restart automatically even when battery is about 90% or battery is 40% and it continue this from last 2-3 months.
and after restarting battery percentage is also changed, see attached pics.
i am tired of this rebooting , i observed that restaring is mostly when i connect to calls or text msgs.
can somebody pleeeeeeaase help me.

Does anyone have any ideas? Today the phone lasted around 12 hours but with minimal use which isn't really good enough. I thought rooting and flashing would improve battery life but so far I am disappointed. I may try another ROM tomorrow.

This really sounds like your battery, especially if it's not the original or equivalent. But, it could also be an app on the background, keeping your phone from "deep sleep". Bad cell coverage (very low signal) also drains your battery relatively quickly when you're on 3G. A good WiFi connection consumes less power than 3G with bad signal. Another possibility could be (but unlikely) is that your phone is intended for another region and thus having trouble communicating with the GSM network.
- Check your battery.
- Check what your battery is used for.
- Check your battery time with network set to GSM only.

Still you keep saying "after rooting" which is significantly different from unlocking the bootloader and flashing. Furthermore, to me it seems far more people report "better battery life" with their new roms.
About initially flashing the rom: i thought format of system, data and cache (including dalvik cache) ought to be enough. It has had somewhere between the 10 and 20 charge cycles by now. Battery life improved a little, but it's still far from acceptable. The battery percentage between reboots should only differ marginally between reboots (might need a few minutes of usage to become accurate). Also notable: over 20% difference in percentage reading between rom and recovery.
I wouldn't mind investigating this. So I wonder if anyone with "proper" battery life could provide me a "dumpsys" for the battery service and would perhaps have the time to take a look at /proc with me.

i unlocked the bootloader and root the device at the same period and i stayed for months with the stock rom
i don't know which one is responsible for percentage misreadings
also don't get confused
i am talking only for percentage misreadings and not for better battery life
and only when you charge the device.not unplugged
of course i had(and i still have) very good battery life with whatever rom i have flashed
by the way i have noticed the percentage difference between recovery and rom but i don't remember if it was 20%

Alright, thanks for clearing that up. I really want to solve this issue, so I'm quite keen on getting the facts straight.
Back to my issue then (yeah I'm effectively hijacking this thread): is it possible the percentage misreading is causing the battery not to fully charge and/or discharge? Or should I direct my search to another cause?
This is what I found (or did not find) so far:
- Stand-by time seems great, the drain occurs when the screen is on.
- There is nothing in the normal battery usage (usage goes to screen)
- I was unable to detect an obvious culprit with better battery stats.
- I did notice that when I do a dumpsys, service battery shows voltage in V, while my Sony shows it in mV.
- I tried offline charging for about an hour today (light still orange), after boot the battery indicator showed 100%. It dropped to 86% in 7 to 8 minutes.

probably never truly reached the full charge(100%) when charged it in that one hour
by the way how old is your battery?

[Q][SOLVED] Device turns off at 45% Battery

Hello enthusiasts,
I'm having a problem with my HTC One Mini (from German Telekom).
The device keeps turning off at around 45% battery charge. There is no warning prior to the shutdown. You can briefly see the "Battery is low!" warning for a tenth of a second until the phone shuts down completely. It can then not be turned on again unless I plug it into the charger. When turned on immediately afterwards, while charging, the battery status has changed to 0%.
There is a screenshot attached which shows the Voltage of the battery about 2 minutes before the device shut down.
I have already used the search and found numerous threads about devices shutting down with a high battery load, but the linked tutorials are often obsolete or unappliable.
I've been studying Wikipedia articles about Lithium-Ion batteries which say that the lowest voltage for a battery generally is 2.5V. Many manufacturers implemented security measurements that keep the battery far away from this low voltage level. I expect the 0%-load to be around 3V, but 3.3V should still be rather "loaded".
Concerning the overall device duration after a full charge: It has become far worse. After first flashing Cyanogenmod M11 Snapshot M6 a fully charged battery would give me around 20h of time until it would die. I've always recharged the device when it reached about 20% charge, before it turned red. Now it barely manages to get to 12-14h. And I don't even use it heavily.
I've already tried some battery calibration apps, but they all haven't shown any influence on the symptoms.
Information about the system:
HTC One Mini
Cyanogenmod 11, Snapshot M11 released on 2014-10-08 02:18:05
Battery Apps: Battery Doctor, Greenify (no difference with or without these apps)
I'd be glad to provide more information on this matter if I forgot something, but I hope I got everything you need. Would greatly appreciate help as this problem is slowly grinding my gears.

I've had the stock ROM installed for about 7 months until July and then I've only installed different versions of Cyanogenmod.
Namely Snapshot M7, a Nightly one from July, back to Snapshot M7 (at this point, the problem with the battery started occuring), then a nightly from October 6th and just recently the Snapshot M11. It should be noted that I've always wiped the system partition before installing a new build.

Flash a stock ROM and see if it still happens.
I have this problem also on any roms. But my isn't at 45%. It's usually at around 14% or 30 something. After it reboots my battery will be 0%
I've had the stock rom running for some time now and the battery display is absolutely fine with it. As soon as I go back to my CM M11 backup and recharge the phone, the measurement gets all confused and the phone starts shutting down at ~45%-50% again.

I have the same problem. As soon as my phone gets to about 40%, the battery drains to 0% within minutes, even while the screen is off and no data is being used. My phone is just over a year old and running a rooted, but stock version of 4.4.2. I don't think it's ROM related since it only started doing this recently. My guess is that our phone batteries are malfunctioning. Check out this person who has the exact same problem I have on the One M8:
http://forums.androidcentral.com/htc-one-m8/396770-htc-one-m8-battery-drain-40-60-0-seconds.html
His screen shots mirror mine EXACTLY. One thing I discovered is that while charging from 0% while in recovery, I was able to see my battery percentage jump from 7% to 50% when I booted to the OS. The battery then died again minutes later. This only happened once, but I'm guessing that our phone might be displaying a higher percentage than what is true just before it dies.
I have a strong feeling this might be CyanogenMod related, as it is known to have caused great problems on dozens M4's with overheating / strange battery drain / weird stuff like that, among many other bugs.
If I were you, I would do a fully clean install of a stable Sense-based ROM and kernel on upgraded firmware and see if problem persists.
Upgrade to the latest TWRP recovery
Wipe everything
Factory/Data reset
Advanced wipe: Cache / Dalvik Cache / System / Data / Internal Storage
Format Data
Upgrade your firmware, if not done yet
Install latest InsertCoin, choose "Perform a full wipe" option in AROMA
When installer finished, uncheck "Reboot phone now" and get back to recovery
Wipe [Cache] + [Dalvik Cache]
Install latest Xceed kernel (for Android 4.4.3)
Wipe [Cache] + [Dalvik Cache]
Reboot
I wish it was that simple. Thought CM may have some known issues, my device and the other example I linked to are running stock Roms.
If it wasn't happening every single day, it wouldn't be such a big deal, but now I'm seriously worried that I can't get a full days use from it anymore and it's barely over a year old. Sending it back to HTC would be a huge pain since I'm rooted. Though I guess it would be worth it in the long run to finally have a phone that doesn't shut down at 40%

Hello everyone, sorry for the delay.
It looks as if there might be damage to the battery as the %-display for the battery is still wrong on a Stock ROM (rooted and outdated) that I've had on the device for a week now.
Okay guys, what to do next? I guess I would like to completely revert everything and reset the phone to 100% stock. Would you guys recommend opening a new thread for that?
Anyway, here are some details:

I'm running a Stock branded ROM (T-Mobile Germany) with Sense 5.5 and Android 4.4.2 which is OUTDATED, however using the stock Recovery, I can NOT install OTA Updates as it stops at 50% showing the attached image (courtesy of droider.eu).
So the plan is to get the default Kernel (remove root), make the Stock ROM updateable, remove TAMPERED [might require S-OFF if I'm correct] and get everything LOCKED again (and not RE-LOCKED). I need your help to achieve all of this and it would be awesome if you could help me or just tell me to open a new thread.

I am in the same boat with you. I have completely given up on this battery. It's not ROM related. The battery simply doesn't hold a full charge anymore and the only remedy is to send it back to HTC for replacement. Since my phone has no insurance or warranty, I'd have to pay for it completely out of pocket. Fortunately, I've got my old HTC One S that still works perfectly and just loaded the latest KitKat Rom to it. The battery life and over-all performance of the One S is nearly better than my One Mini. I'm not feeling very compelled to get it fixed at the moment, but I'll let you guys know how much it costs if I change my mind. Good luck with yours.
Thanks, I'll just have to get mine fully back to stock to be able to turn it in... Hope it'll not be that pricy for you.
Can you get rid of the tampered warning on the boot screen? I thought it was irreversible. If not, I don't think HTC will warranty it.

Of course you can, at least I assume you can. On the HTC One there are already guides and I guess the Mini is not that much different. It requires S-OFF though, so at least I would have to tinker around with my phone even more.
Our Plain vanilla -stockROM One mini is having similar issues:
It shuts down at battery 30%
- removed unneccessary app's - no result
- Factory reset - No result
Contacted HTC support, they advised to run self-test ( *#*#3424#*#*) in safe mode
Tried that: Boot-up in safe mode - charge full - batterytest : Put it away for the night while batterytest running, hoping for a report in the morning. Unfortunately no report, but a battery status of 1% - so no shutdown at 30%
Second time: Charged full in regular mode (100%) - reboot in safe-mode: Battery shows up @57% and could be charged for at least one hour.
Ran battery-test : after one hour of testing, battery = 91 % while 71 % is lower limit for failing battery, so battery succeeded.
Third time: Just testing the difference between battery-status in regular mode vs. safe-mode
Full charge in regular = 50% in safe mode (and able to continue charging)
Don't want to sent it away for repair: expecting to have it sent back after a couple of weeks: " we did the batterytest, and it's functioning fine. Your device is not broken"
My idea: something interfering with the battery-status indicator ?
But what ?
Any ideas ?

not sure it works, but try this
the wiping the partition cache from stock recovery is not quite the same as factory reset

Thanks for reporting a similar problem to mine. I haven't gotten to fix mine, yet, too. Mine even powers down at 75% Battery and now has a horrible battery life of about 2h of normal usage (occasional screen activity, listening to music).
But how did you find a batterytest? I can't seem to find one in the safe-mode via that dial code. Can you explain where you found the battery test?

Wow - I wish you had posted this 2 days earlier! I just had a new battery purchased for my phone and I'm getting a local repair shop to replace it. Sounds like my battery could be fine and I will likely have the same results after it's replaced!
If you fully charge the phone in safe mode, does the phone battery still last the appropriate amount of time in regular mode or does it still shut off prematurely?

Not sure if I understand this: I did the Power-button - volume down - 'Factory reset withour keeping data" - as given on the HTC website

It still does: Fully charged in safe-mode it shuts down @30% - does seem to last longer to reach 30% level
Last night I tried a different trick:
After shutdown @30% I kept the phone off and recharged it to 29 %
I put the phone back on and drained the battery to 0% - ignoring all warnings ("please charge .... CHARGE ..... G*DDAMN START CHARGING, I'M FREAKING DYING HERE ....)
Recharged the battery while powered off from 0% to 100%
Tested this morning: Same battery level in regular mode as in safe mode (98%)
Hmmm, I seem to remember doing some thing similar by accident with my phone when I stopped charging around 30% to use it. It drained to 0 shortly after and I fully recharged while in recovery mode. The battery seemed to last longer that time, but any subsequent charging before letting the battery die seemed to result in the same poor battery life. It's not a real solution but if you can confirm that yours acts similarly, then it's more info for us to have as we try to figure this out.
