Is anyone else getting massive battery drain?

Since I upgraded tp 4.0.4 my battery life has been completely terrible (nexus s GSM, stock, latest glados kernel) even though I don't use it the entire day, it drains over half in about 4 hours. Anyone have any idea what I can do to fix this? It was perfectly fine before the update and would last days if I didn't use it, and about 12 hours if I did. Right now it's just unusable.

BetterBatteryStats and/or a fresh install (data/factory reset, format /system, optionally format /boot, install ROM).

Are you using a custom ROM?
I've had the same problem when I was in stock 4.0.3, which is why I decided to root my phone and resort to custom ROM's and kernels. Now my phone is doing ok in the battery department and is also much more snappier and smoother. Oh and most custom ROM's are already using 4.0.4 anyway.
Let's try and be scientific about your problem, here are some things you may want to try out first to improve battery life:
turn off wifi when not in use
turn off automatic syncing if you don't need it
set your network mode to 2G only if you're not using the internet
turn off mobile data when not browsing/using the internet
install the watchdog lite app/widget from the Google Play store so you can monitor rogue apps that are sucking up juice
do not set your screen brightness to AUTO, but manually adjust it when you need to. you can do this either in the settings menu or thru the power control widget
This are the things I can think of off the top of my head. If this doesn't improve your battery life, even just a bit, you may have no choice but to resort to drastic measures....and go to the dark side.
Hope this helps! Cheers!

mine is okay
Batt I think it quite good on 4.0.4. I can get about 23hrs of usage. Some wifi, some 3g (fb, whatsapp, updating apps, email), some music. Stock ICS.

I had this issue after stock 4.0.4 update from 4.0.3.
I found mediaserver using more battery than it should, so I;
1) Copied all files and folders from /sdcard to PC
2) Re-format /sdcard
3) Re-store all files and folders back to /sdcard
Mediaserver process is now minimal and battery is good again

Ok thanks for the suggestions guys, reformatting my phone would be alot of effort on my part due to how much time I spent setting it up so I would like to use that as a last resort.
I installed battery stats but I can't decipher what it's saying so if someone would be as kind to explain? I took screenshots of everything in an album and I would really appreciate it if someone had a look in the album below.

Well for one, you have chunks of bad signal(red bars). That right there can kill a battery quickly. The other stuff you may be better off saving the dump file and posting it as an attachment over at the BBS thread. The guys over there are pretty informative and may be able to give you more stuff to look at to help you out.

The red bars are when I was using the underground, the battery drains just as fast overnight. I will look for that thread, thanks.
Edit: I do not stay on the underground overnight, and I have a good signal in my apartment (you can see it's fine when I arrive)

yep...a weak network signal will drain your battery a lot faster. if you're not using it to text, call or surf, or if you're just going to play games, might as well go airplane mode for a while, or at least until you get above ground where the signal is stronger.

After a good couple of hours not using the phone in a good signal area create a log and post it. Preferably get the hours just after charging.

Edit: should mention I just remembered I had it on airplane mode overnight once and it still drained.

Ok nevermind just did a reformat new rom etc.

Sorry guys, but after reinstalling I am STILL getting the battery drain issue.. Was a clean install but reinstalled all my old apps and settings. from full to 28% in 5 hours with very little usage.

Please someone take a look!!!

I'll have a good look tomorrow with some suggestions. Had a fair bit on the last couple days with minimal internet access.

What ROM and Kernel are you using right now?
There are a couple of interesting details there but nothing that i can point out that will take you from 100% -> 30% in that time.
Some things to test:
-Turn phone off (noting charge), remove battery, replace battery, leave phone off overnight and turn it on in the morning, again noting the new charge
-Keep data off and see if battery is still draining / Airplane mode
-Uninstall half of your apps and see if it still happens. If not, add half of the apps you uninstalled. If so, uninstall half of the apps you have left, and so on.
-Do a clean install and try for 2 - 3 days, see if it still happens (preferably a stock ROM, preferably from fastboot images)
-Attempt going back to Gingerbread and try for 2 - 3 days (preferably a stock ROM, preferably from fastboot images)
These steps can (and should) be done pretty much in order and will rule out ALOT of possible reasons and give possible solutions some merit. Let me know how this goes.

Using latest stable cyanogenmod + tried glados and netarchy and matrix kernels, all the same result. Will try what you said, also I bought a replacement battery to see if the actual battery is faulty (weird because it used to be fine). As for the airplane mode thing I already tried that, to no avail.
edit: should add that was using stock 4.0.4 before cyanogenmod.

Battery problem

Hello, i'm a newbie to xda developers... I had some problems with my Sensation... I am really a newb to those stuff since i never rooted a phone... The problem with my phone is that the battery doesn't slowly drain... I let it to charge for like 5 hours to get to full 100% and then from 100% it goes to 60% in like 10-20 minutes while i use it ... Other times the battery shows to have more power and other times it straightly goes to 40% from 100%... It drains so quickly i can't even go outside with my phone since its battery gets empty... Sometimes, even if the phone is 60% it randomly shuts down and have to restart it for like 5 times to get it work for at least 10 minutes. Might it be the battery? I tried going to recovery mode but i get the red triangle with an exclamation sign in it... Any reply is appreciated, thanks!

Maybe your battery is rubbish and you should just buy another one.
Although is one thing you should try first, recalibrate your battery.
What all these methods amount to is how to teach your phone about battery performance. Calibration is about enabling your phone to provide accurate estimates of remaining battery charge and will not, in and of itself extend the usage you get on a single charge (though it may possibly prevent the phone going into power save modes prematurely, wrongly believing the battery to be lower on power than it is).
The phone stores information about the battery in a file called batterystats.bin which sits in /data/system. Normally you won't have direct access to that file, but you could find it with an app such as root explorer, which allows complete access to the phone's file system.
When you install a new ROM, or a new battery, or perhaps periodically as the battery ages and performs differently, you need to get a new set of battery performance statistics.
By charging the phone to 100% you are starting at the known maximum for the battery. At this point, the batterystats.bin file needs to be deleted, which forces the phone to recreate the file from scratch, using the information it is about to collect. It doesn't matter what method you use, battery calibration app, or from within recovery - they all do the same thing and delete this file.
The phone is then allowed to drain fully. This gives the other end of the scale, the known minimum. The phone then has then experienced the full charge/discharge cycle of the battery and stored that performance information in a new version of the batterystats.bin file.
Now that the information has been saved, the phone will (hopefully) be able to provide accurate estimates of the battery charge level, regardless of how much of the battery charge you use before reconnecting the charger.
If you don't have root access you can download an app from the market called "Battery Calibration". It does the same thing, deletes the batterystats.bin.

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

Well, yes I guess you should root your phone first, but I'm not sure
A guide on how to root your Sensation can be found here .You should only do the steps 1-3.
If you don't want to root there is another method somebody wrote (I haven't tested it personally)
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds minimum
6. Put back the battery on the right side.
7. Turn on the phone.
Than you should be OK:good:
If you get the same result after "battery calibration" I suggest you buy another battery.
Hit THANKS if I helped you

Hello, i have two more question related to this thread... Is there a way to calibrate my battery without root access? And will buying a new battery surely fix my problem? Thanks again!

You might be able to get a calibration application in the playstore. However most I've seen require root access. But look, they're might be some without root requirement. As for your second question. Nothing is ever 100% guarantee that it will solve the issue. These are suggestions based on the information you provided regarding your issue . How can anyone be 100% certain that will solve your issue. It's defiantly a possibility it will solve the problem but no, for 100% certainty, I don't think anyone can say that. It's defiantly worth a try ! Then you can see if getting the battery solved the problem. I hope it does fix your issue and wish you the best .like I said, no one can be 100% sure but it's defiantly worth trying!Sent from my HTC Sensation 4G using xda premium

Everything said in this topic is PURE NONSENSE. It was even featured on the front page that wiping the battery stats DOES NOT DO ANYTHING. See this article for more information > http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The only thing you CAN do is charge your battery to 100%, and let it drain to 0%.

Aparently, after i cleaned my battery contacts it DOESNT jump to random values... drains continously.. SO i think the problem is fixed... atleast for a while! I'm new using a smartphone and the battery is a little 2 weak as i was used to my other non-smartphones... I think that's the battery life a 1520AMH can offer me on a sensation! The uptime for it was 6 hours from 100%... thats really weak ( i used the web and games).

[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.

battery at different levels when i reboot

Hey dudes i have been having this issue for some time but I feel fed up now...I am running CM 10.1 on the DHD and sometimes as I use this device my battery meter shows that I have used all the battery which prompts me to recharge...funny part is that mos times if i reboot i get the battery level back up to something like 35 - 50%; Now this is crazy since once I used a battery calibration app (free version) hoping to solve the issue but this issue never went away even after calibrating the batter with this app... I wonder if there is a way to solve this or maybe reset the battery or something...Thanks in advance

Maybe you should do a Wipe Battery Stats, From CWM
1. Charge 100% of Battery
2. Enter on CWM Recovery
3. Choose Advanced - Wipe Battery Stats
4. Reboot and leave your phone plugged for 15 min. then you can unplugg and use it
maybe this could resolve your problem:good:

I've noticed something similar on my DHD too. Sometimes the percentage can increase or decrease between reboots... A few times it's gone down really low, to say 11%, and stayed there until about the time it would actually be 11%! It's probably related to my battery being pretty old.
@manuelchef89 If I have understood correctly, what you have suggested happens automatically when you do a full charge anyway. Maybe someone who knows for sure could confirm.

you should buy a new battery

Sometimes is a kernel problem, but you should wipe the battery stats

Take out your battery and see if your battery get any fatter than before, if it's bigger/fatter, your battery is dying.

[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?

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.

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?

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.

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.

"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

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?
