Stamina Mode calculation issue

Previously with stamina mode on it would show standby time of a couple if days. Now, it's showing only 14 hours, no matter whether I switch it on or off. So, seems like a problem with the stamina mode calculation. Anyone experiencing this?

I think it learns from your usage.. As mine now only shows 8 when on 7 hours when off
But I get several warnings of apps preventing stamina.. This could also change the calculation

I had this problem more than once, for God-know reason. I found no way but to reflash rom. This miscalculation is no much meaning and affects nothing, so ignore it.

i see this
But don't think about it cause ur phone will properly (battery is healthy 100%)
1. that might be a bug in calculation of estimated time
2. learning how u use ur phone
> the guru app of snapdragon also works based on how u use ur phone.
and i think it will collect required data and refresh itself after 100% charging.
i had 4day
then i got 1days
after that i got 2.5days
and for last charging i got 17hrs
> my opinion; it s about learning
check it urself remember how u use it for last days.:good:

I did a repare in pcc and it did it Good
Now the function is good in full charts it gives 4 days and 17 hours

Well still no luck with the calculation even after fully discharging the battery and then a full charge. Maybe it's a software bug. Anyway, I did a factory reset and then restored. Seems ok now but I will monitor and see if it reoccurs.

Hi, the problem is maps app of google, I solved the problem with a factory reset and freezing maps app

Stamina Mode is working properly
*
i had 4day
then i got 1days
after that i got 2.5days
and for last charging i got 17hrs
*
100% charge > 17 hrs
>>> ~ 37% charge > 1day
22% charge > 15 hrs
Stamina Mode learns How you use your phone.
the day before 17hrs i used it alot
after 17hrs i used it alot again till ~70% charge.
then i didn use it for half day So in ~37% power management showed 1 day.
SO There s no problem with battery configuration & NO bug in Stamina Mode.

[BUG] Battery Bug for Stock 4.2.2

THIS BUG CAN DO HARM TO YOUR BATTERY! BECAUSE YOU WILL NEVER KNOW WHEN THE BATTERY DRAINS!
As we all may encounter the battery bug after upgrading to .423 fw. When one restarts his phone, he has chances that the battery level of the phone rises (e.g., I turned off mine just now at 26% and turned it on showing 51%). This has been confirmed by many users in the forum, so I believe it is a firmware level bug of 4.2.2.
Is there any one willing to pay some time on fixing it? Coz this is a quite crucial bug for us, we dont know when will our phones automatically turn off! Thanks in advance
I believe its not a caliboration thing coz we also upgrade or wipe our devices before, and no such thing happened. I think its a firmware or kernel level bug. Does anyone who flashes a custom kernel also encounter the same problem?
It seems that Spanish FW is free from this bug.
http://forum.xda-developers.com/showthread.php?p=43261281
plz report your rom or base FW in the reply. Thanks.
[NEW EDIT]
It seems that I fix the bug. The battery jumps when the phone restarts, so I think there is something during boot which causes the issue. I delete the XZDualRecovery, and test the phone several times, and its fine!
Deleting XZDualRecovery might be a temporary fix, so you can choose what to do
[NEW EDIT 2]
someone reports that they dont encounter the bug and believes that its the calibration thing. i declare again that i DID the calibration and the issue was still there. for me, at least, deleting XZDualRecovery fixes the bug. plz report more details in the reply, like fw, root or not, recoveries. Thank you

I don't think there is a bug here.
Never happened to me,cause i did full wipe while flashing.
Maybe it happens only for users that didn't wiped everything.

so yeah, +1 in this though I think this is happen in kernel level? which means us with lock bootloader can't use the fix... CMIIW though

There is no kernel for 4.2.2. DoomKernel supports fw before 423. Correct me if Im wrong. Also in LB and know not much about custom kernels.

yes this issue exist. it happened to me when i updated to this new 4.2.2 also i have black dots in camera and the back cover of my xperia z is not correctly glued. i hate sony right now

hello all me too experienced the same problem but I successfully regained my battery life. Here is what I have done....
1)First I drained the battery fully until mobile gets switched off
2)Then I left the mobile to cool off for half an hour
3)After that I charged the battery upto 100%
4)Following this I switched on the Mobile and did the battery calibration by using 'Battery Calibration' app
5)Again I fully drained the battery and charged it again to 100%
Now the battery life seems good. I checked this by using WiFi whole night....battery lasted overs 12hrs

Battery Bug
Just updated my Xperia Z today with a full data wipe from 4.1 to 4.2.2 and I've experienced the same problem from 26% of battery to 52% after reboot.

This is exactly what I concern. I dont know when my phone is going to off, and it could be big trouble when there is no access to the charger.

Maybe we just need to recalibrate, drain battery to 0% and fully charge it to 100% while the phone is turned off.

plz give some feedback if it works

I experiencing the same issue. 2% to 55% after reboot. wow... 4.2.2 doesn't bring anything for me to consider to keep it. so back to 4.1.2 (.4.3.4)
But one thing for sure (never discharge a lithium ion / polymer battery from full to 0 they don't like it) you could do that with nickel cadmium/ metal hydride batteries ant they really thank for that if you keep doing that you just kill your battery before its due time.

Xperia V - Huge battery drain (Google Services)

My Xperia V was draining much battery while sleeping, so yesterday I flashed cm-10.1.3-RC2 hoping it could get better.
But it's still draining almost 30% in a period of 8 hours, while I'm sleeping.
I can notice a huge drain caused by Google Services and have already greenified some apps.
It can't be normal, right?! Could someone help me?
Despite this problem, now I have a really better smartphone... So, thank FXP and, please, keep supporting Xperia V. :thumbup:
Sent from my GT-I9300 using xda app-developers app

Not sure if this question belongs to be an own thread...but ok. here we go.
from my experience with Cm i can tell you, if you want better battery life, then you maybe should use a stock firmware!
I used CM and AOKP some weeks before, but the battery drain wasnt normal, not to say horrible.
But this is my experience. You should ask in your CM-Rom Thread, or CM Q/A Thread i think.

I'm a new member and I couldn't ask this in CM thread
I understood what you've said, but even using stock rom I was having that percentage of draining at night...
Do you have a Xperia V?
Could you (or someone else) tell me how much draining is considered normal in the period I've mentioned before?
Sent from my GT-I9300 using xda app-developers app

30% in 8 hours means that on average your battery will last a day.
That is perfectly normal.
Also, if you keep flashing stuff and installing apps then it drains battery quicker. Leave it alone for a week and see if it settles down.

Sorry, i have a Xperia T.
in the xperia T thread of tilals unofficial CM build (development section) someone mentions also such problems:

So, i guess its normal? But an actual CM User can give you better report. Not using it anymore.
awww, gregbradley?
30% in 8hours sleeping? horrible....but you are right, let it settle, fmlogin

Omg, my Galaxy s3 loses only 2% in the same period while sleeping, it's a BIG difference
I had been facing this problem since I bought this phone (2 months ago), that's why I tried to flash CM yesterday... So, I think that nothing will change if I just wait...
Anyway, thank you guys...
Sent from my GT-I9300 using xda app-developers app

apologies, I didn't see that it was 8 hours while you were asleep. That is not right. But it may be because its working hard after a flash. Please leave it for a while and it should settle, or install better battery stats app (Free on xda) and see whats keeping the phone awake.
Also check what your cpu is set at and the governor, if its on performance it will be maxing out all the time..

The governor is ondemand and I didn't change the clock of cpu...
I'll install the app and come back with a screenshot, so I think it'll be easier to find some problem

Sent from my GT-I9300 using xda app-developers app

Some screenshots.
The graphs show another problem: it is like the phone just know that lost some battery when I turn on the screen.
For example: if I leave the phone with 95%, it pass the hole night "thinking" it has this value, but when I turn on the screen the battery instantly loses around 15%, this "fast drain" stabilizes when it reaches the "real percentage".
Could it be a hardware problem? The battery itself...
Has already someone noticed something similar?

Xperia Z DEad on battery work on cable. Solution?

Ill try to explain my problem in detail...
I have an unlocked bootloader Xperia Z
I flashed first 4.4 build to try the new kitkat android....
On these build i have incredible battery life but, obviously other kind of stability problem....
Then I reverted back to Monxified 4.2.2 rom, and I make a little mistake (flashing new rom with phone at 40% battery with cable plugged in.....
After this i start experiencing bad battery life and suddently shut down at 30-40% battery level....
I tried various full charge (even with phone shuttend down) and long time charging even after the battery indicator is full......
Nothing changed and situation get worse with phone shutting down at 60%...
After this i tried move to 4.4.2 beanstalk.....
It seems to work a little better but again phone suddently shut down during usage and start to be unable to go after boot logo (before bootanimation)
If I power on phone i see the kernel logo and when boot animation must came in phone simply shut down.....(it doesn't reboot or go in bootloop it shut down and I have to push the power button to see the same crap)
With power cable plugged in phone work without problem, but even after startup if I remove cable phone shut down after 30sec-1 min....
BUT, and this is the strange one...
If I boot in recovery i can do what i want....even withoud external power in recovery i can use phone for 30 minutes adn over without shutdown...i can flash rom and other stuff and my Xperia Z doesn't turn off....
I'ave also tried to flash a completely stock FTF with sony official kernel (4.2.2 and 4.3 versions) but nothing chage....
Leaving aside recovery...every rom i flash simply can't go after kernel logo without external power
,

I often flash new roms with cable plugged in... So, you have already done a full wipe, so try to use the battery calibration app, maybe the battery stats are corrupted.

Indeed. The option to delete batterystats.bin was removed from most custom recoveries long ago as it does nothing.

what make it worse is after several flashing ROM and fresh FTF,suddenly my phone cannot on. push the power button,its vibrate and boot till sony logo and then shutdown. if i turn it on while pluggin charger is also the same,shutdown after sony logo and repeated itself.
any suggestion?
some one said the culprit is chargemon.stock ..but i already flash a fresh FTF.and if i plug on my pc, it will automaticly boot to flashmode without me pushing vol+ button,but it will shutdown after 30sec.
really need some expert help cause im using my phone as a navigator on work.:crying:

Can be the MSM_HSIC_HOST kernel wakelock that is causing your battery drain..

im using 3g all the time and i dont have problems i think u were using your phone differently so you cant compare battery life

There is some strange issue with 4.3 firmware. I've incredible battery drain too.
In early versions i get full one day usege with 3g only network and 3 exchange mail account on push mail settings. Now, nearly 6 hr, and battery low alert.
Realized fast dormacy, disabled for my network, did not solved. Totally uninstalled fast dormacy stiil same. Exchange servise drains all the time.
There is no much wake lock in battery log, there is no special application that drains, but still, like phone does not get in deep sleep state. I dont have and horizontal line in battery stats.
Most of people says, battery is better then before, but most of them do not use phone like me.
Seriously, i consider to revert back 4.2.2
Ps, i even tried to factory default. That was pain in my a.s. because of installing applications and made settings. Still i dont have proper solution.

the only problem i'm having is while i'm using internet otherwise the battery live goes on and on
i guess the 3g network coverage suck in my area but 2g is very slow when it comes to browsing, it's fine for whatsapp but whenever i want to do something else i suffer

Stock kernel is so simple developed and doesn't have any real power saving functions at all. Just like Sony throwed some kernel coding together and didn't really test it at all on anything else than stability..
My opinion is this.. Using stock / Advanced stock kernel is like demanding battery issues for free.

can you help me with rooting and installing a new kernel ? ive 4.3 as i said and i don't know the status of my boot-loader either

Well I've noticed that after a rather short amount of time, a lot of ram is being used and the battery drain is enormous!
Never had so heavy battery issues, even.with different kernels and Roms.
Now.completely on stock and wow.. @ work.for 12 hours, no usage at all, battery dropped from 100% to 36% and energy options telling me that ANDROID OS used 59% THE WHOLE TIME

If you don't know your status of bootloader, most likely it's locked. You can unlock it if your bootloader unlock is allowed. And there's no custom kernel for 4.3 yet.

Better go back to 4.2.2 until Sony got time to fix their disaster of 4.3 release!

4.3 is fine for me. Existenz v5 is even finer.
