heavy battery drain and mobile heating up since last evening

Hi,
I was running MIUIXperience V5 and everything was fine till got a random reboot last evening and after that, battery started draining very fast doing nothing 20-25% in an hour. Mobile is heating up a lot now back side near camera and charging also became very slow (30-40% in 4 hours). Tried full wipe and reinstalling the ROM but still the same issue, wiped battery stats as well.
I was getting 25-35 hrs before this so doesn't look like a fault in battery. Any help will be highly appreciated. Thanks.

Seems a hardware issue to me. Maybe try to swamp battery's and see if the current one you're using is busted.

Thanks for your help but I still doubt the battery as when charging in powered off, it charge well & quickly as before

Can you try another ROM? If it would work ok with another ROM that would put the hardware suspicion aside. If it still keeps the same with a different ROM, then it's most definitively a hardware issue.

I have tried another ROM and same ROM with clean install, they seem good as before the issue but as soon as I enable root permissions, battery started to drain fast again (35% in an hour)

got a similar issue with mine, usually my battery stills 20hrs, and that's ok for my usage, I'm running brainmaster cm9, but same with CDA 2.0.0, randomly the phone, in some case after a reboot or disconnecting power cable, start to drain battery and become hot, in battery usage stats AndroidOS is the main issue and android.process.acore the resource that never sleep,
I think this can came from a bad deep idle management on some rom-kernels combo or ics 4.0.4 issue, but I nobody to say this...

I tried different MIUI Roms but issue remained same. Then I installed Androxide after full wipe and now seems to be working fine (72% after 7hrs). Still can't figure out what is the issue that different variants of MIUI Roms after clean install and battery starts to discharge heavily.
Tried going back to MIUI but probelm came again and after restoring to Androxide, again working fine

I suggest to install an app like Quick System Info anche see id there is a process running high on CPU usage: there you can see its log and try to understand what's happening...
BTW, I started to have some massive drain with the last CM9 nightlies: it was the Phone app that sucked all the juice in a few hours.
I wiped & reflashed dozen of times, checking if the drain was caused by some app, until I used Quick System Info and saw from the logs that the problem was the new 2g/3g toggle widget: I had set it to "3g preferred" but this caused a loop. Setting it to "2g only"/"3g only" fixed the issue.

First, MIUI is a Chinese ROM.
Second, Chinese things are always known for bad quality.
So MIUI is bad

Really, dude? Maybe you should take the tin foil hat off.

[Q] Cell Standby / Phone Idle Drain - Embryo 3.2 / UCLE2 / Cymbaline 1.5

Hey Guys,
Let me start by saying that I've spent the better part of 3 days searching XDA, google, reading various other forums for answers to my problem before I decided to post this. Even if the answer was close, or for a different phone I tried all the recommendations to no avail.
I recently just got into the whole rooting and flashing thing. I first tried cyanogenmod9 nightly, and then Embryo 3.2 which I immediately fell in love with. When I flashed, I followed the instructions step by step - wiped all the data, cache, dalvik, formatted then did it all again. Everything is working without a problem. My issue is that cell standby and phone idle is absolutely crushing my battery. I went from getting 17+ hours of normal use with room to spare before charging for the night to barely getting through a day of work.
I installed better batter stats, badass battery monitor, and as a last ditch effort juice defender - hoping that if I let it control the radios and have them off it would curb the problem. Juice defender checks my emails n' all once an hour and it's no help at all. I've burned up almost 20% in 4 hours and i haven't even touched my phone except to see if JD was actually working. Badass battery monitor shows the radio as the biggest drain, and better battery stats... well, frankly, the info it reports is WAY over my head..
My phone is a fresh install of Embryo 3.2, UCLE2 radio, and cymbaline 1.5 kernal. I'm running go launcher, beautiful widgets for time/weather, and go contacts widget. That's it. I read about the phone idle, charged it to 100%, cleared the battery stats in CWM trying to calibrate it and it seems to have done nothing.
Also, I understand the radio works different for everyone. I think my issue is that if UCLE2 is from 2.3.6 OTA, which is what I was using post root/rom, and what i'm currently using now.. why is it a problem now vrs before?
Should I just download all the available radios for the skyrocket, and try a new one every few days to see which works better?
I'm really just seeking a comprehensive answer to my problem which I can't seem to find anywhere. I wouldn't have posted this if I didn't believe I exhausted all my available options. sorry for the wall of text and thanks for taking the time to help!

It's very obvious that many, many people have this problem, but everyone tries to tell you to battery saving tips that just help to cope with the problem but don't fix it at all.
UCLE2 is not from 2.3.6, it's from the second most recent 4.0.4 leak, by the way. I don't really think this is a radio issue, though I did notice I have a problem in UCLF3 and UCLD2 Odin, but not in UCLE2 or Gingerbread. I'm convinced it's something to do with how these ROMs are flashed. I'm going to try CWM to UCLF3 from UCLE2 and see how that goes.

Yea, please let me know what you find. I'll try a new radio when I get home. I'm not going to bother trying to flash a new rom, or this one over again as i've already done it multiple times - the issue has not changes...
cell standby, phone idle..

Get rid of jd first. It makes ics worse. In fact better battery stats is the only "battery assistance" you should keep. Then reflash everything. If you restore with titanium backup, don't restore system data. You'll have to re enter your email accounts and stuff but your contacts should sync once you do. And every time you flash a new ROM it needs a few days to settle. It will burn extra battery in those few days. And I don't know how go contacts widget works, but it may have some interaction with the phone apk that mohan hasn't engineered for, keeping it awake. I'd go without it for awhile too and see if that helps.
Also get CPU spy. To see if your phone's getting any sleep. You could be having some kind of wake lock. Reboot when you pull it off the charger.

I think it is in part a wake lock problem, however rebooting after taking it off the charger doesn't help.

New radio won't change that. Unless you're not using the one mohan provides in the embryo thread. Something is bugging out the phone apk. You may want to try embryo 3.2 without the cymbaline kernel also, and see if that's any better.
Also I should say again, whatever is causing your drain problem, jd is making it worse.
Anything that might be keeping the phone awake. Maybe a Bluetooth or like I mentioned, possibly the go contacts widget.

Alright, thanks.
I've done as you suggested and will report back.
I've installed BBS and CPUSpy. (I don't know how to read bbs, so perhaps point out some things i should keep an eye on would help.. )
I've removed juice defender, go contact widget, and badass battery monitor. I'm pretty much stock except for go launcher ex and beautiful widgets for time/weather.
I'll also remove and reset the battery cache in CWM
When i get home tonight i'll re-wipe/format etc etc and start from scratch again... *pout* lol

Yep, thanks for the info. I won't change the radio, and i'll keep using whats in mohans embryo thread. I'll re-flash and leave off the kernal (which, i like because when i talk on phone it doesn't get hot like it used too).
I removed JD, contacts widget, and everything else except data is off.
What specifically should I be looking for under CPUSpy and BBS
THe phone has currently been on for an hour and 50 minutes
spu spy states deep sleep of 80% for 1:26:28
and bbs under "other" reports 69.4% for both no or unknown signal and no data connection for 1hr and 16 min both

No, don't do any of that and don't reset the battery cache in cwm. This might be your problem actually. When you reset battery in cwm you essentially make a new 100% mark. Like, if you do that when you're at fifty percent battery, you just cut your Max battery life in half. So do THIS when you get home. Turn the brightness all he way up. Download angry birds or something and play it until your phone is dead dead DEAD. Then plug your phone to the OEM charger. The one that has a USB plug on the wall end. Let it charge all the way when it's turned off. Then when you turn it back on, hold power and volumes and go straight to recovery. That's the correct time to reset your battery cache in cwm.

Keep everything the way you have it now and do he charger thing. If you're at&t. If you're rogers change to ruxlf3 radio. Actually trying a different radio may not be a bad idea but give each one a day to see how it does. See if that "no or unknown signal" in bbs changes. You aren't having wake locks. Deep sleep is what you're looking for in cpuspy. I think jd turning on and off the data and searching for a new signal caused a lot of the burn so far. Are you in an LTE area? The other thing to do is make sure your apn (settings > more > mobile networks > access point names) matches what is listed in the embryo thread. Keep your kernel and don't reflash anything except a radio. Try ruxlf3 or u...f5 tomorrow.

I'm in AT&T and I work smack dab in the middle of an LTE area with good signal.
I live 60 mi from work, in a non LTE area but still have good signal.
My apn settings were actually set by the phone when i received a call straight after flashing. Att PTA - internet + mms, i'll check mohans thread and see what's up there.
THanks a lot for your help, I really appreciate it.

Ok, I've had some luck getting normal-ish battery life (~15 hours). Still seems a little below what it should be and performance is also slightly sluggish compared to stock, but it's clearly miles better than the dead in 7 hours life I was getting.
Now, I don't know if I just got lucky finally or if any of this actually helped, but here's what I did:
* Flashed UCLE2 with Odin.
* Ran battery all the way down
* Charged battery all the way up with phone off. Unplugged it, left it off, and recharged it a few times.
* Wiped battery stats
* Odin flash CWM (NON-TOUCH version this time)
* Darxide Superwipe (x2)
* Flash CM9, Gapps
* Boot
* Darxide Superwipe again
* Flash CM9, gapps again
* Boot, drain battery all the way down
* Charge battery all the way up while phone is off.
Again, not saying this is a fix just saying what I did in as much detail as possible in case it helps anyone.

just go download embryo 4.0 fast and stable.

So your saying that even with a fresh install (no apps installed) you're having the same problem? The android system seems to be consuming a lot of battery, normally its around 2 to 3%. Do you have an SD card? have you tried scanning it for viruses? Or may be you could try installing an antivirus just to be sure and put your device and sd through a full scan.

android system on my htc chacha is using something like 48%, I charge my phone three times a day, was ur problem related to a virus or something? I try not to buy a antivirus since it costs too much and also I believe it drains much more battery than android system..

I doubt whether a hardware problem could be the cause, android system should not consume so much battery in any case. Did you wipe all data, cache and dalvik cache when you installed the custom roms?

I didn't install a custom rom, the only thing that I did was S-off and rooting the phone, could it have caused this issue?

You said in your first post that you have flashed cm7 and cm9 and I am guessing you must have done it using clockwork recovery. I am a little confused now. Did you factory reset the device?

I did factory reset more than ten times.
Actually, this battery issue has started to happen since I flashed cm9. At first, I thought this came from mismatched RIL & baseband.
(Note : http://forum.xda-developers.com/showthread.php?t=1549488)
Sadly GetRIL doesn't support chacha, so I just flashed back to the one I used before - with full wipe - but it couldn't resolve the issue.
The last thing I could think of was flashing back to stock rom and I followed this guide.
(Note : http://androidforums.com/chacha-all...lash-back-stock-rom-chacha-please-sticky.html)

I agree that it is strange Android System process eats too much of battery, but I couldn't find any errors from it when I checked the process log.

Are you sure there is nothing wrong with your actually battery? try getting a replacement and see if that helps.

To me android system consumes the same amount and I have like 5 hours full use(e.g. browsing + 3G) , I believe there might be a problem with ur own battery, try replacing it and see whether it works for u or not

[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

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.

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

After rooting??? R u sure about that ??
I was suffering same issue before rooting and after rooting..
Wipe battery status is useless here ..
Its HTC's fault....

before rooting?
for me that never happened
also wipe battery stats is useless and indeed it is htc's fault

Just a percentage misreading? But if the phone thinks it's at 100% won't it stop charging then?

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.

since you are completely stock then the only thing i can tell you is to check your battery if it fits correctly
also how old is it?

thanks for ur reply ,
i have inserted plastic card behind battery for proper contact (adviced by many people at xda) but problem is not solved. my battary is 6 month old.
may be it is battery as i purchased from local market.
i have ordered new battery and soon will recive that . will let you know.
i have observed that mostly mobile got restart when i make/recieve calls and sms.

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?
did you try with a new one?
