Drain battery on Xperia SP

Helllo, I recently bought my Xperia SP. I really like this phone. I didn't have any problem (wifi). From the first time I bought my phone, I noticed that my battery is draining too fast. I loose every night about 20% battery. Data and wifi are closed and STAMINA mode is turned on. Do you have any solution about this problem? Sorry for my English and Thanks in advance!!

A few people have complained about this, but for me, with stamina on, standby battery life is superb.
Wakelock detector is available in the Play store - this is a useful tool for seeing what's happening to your phone when the screen is off. With WiFi and data on and the screen off, my phone is only awake 6% of the time and it's mostly Facebook (terrible app) doing things.
With the screen off I might only drop 1 or 2% whilst I'm asleep.

Switch to GSM only.
Besides that it seems that an enabled Google Now is leeching a lot of battery too.

Try to install BetterBatteryStats and make a dump. Then attach log file into this thread (http://forum.xda-developers.com/showthread.php?t=1179809). I hope developer can help you

Try looking in the sp forums for a solution or same thread. This sp forum is getting flooded with the same topic!

1. What ROM (stock?) do u use?
2. What firmware?
3. What baseband?
4. What kernel?
Give us a lil info about what u have in your hands :fingers-crossed:

Well now I unistalled facebook. I'm using stock rom with the latest firmware (.245), without root. I don't have enough apps. Only facebook/twitter and some games. I installed wakelock detector and i saw that facebook is doing the most battery usage.

me either, this sucks, i did a factory reset 2 days ago, at first it was fixed,
but then the wakelocks came back next day, it's the superstamina-xssm again, also with the most alarm

I wonder why u all facing the battery problem...
I'm using C5303 in latest firmware, no root, STAMINA mode off
my off screen battery consume only some internet connection apps if connected to Internet....
And if I sleep usually I will turn on airplane mode, so maybe whole only 1-2% of battery is been taken

I don't know what happening. my battery is draining so fast. With stamina mode on and everything ese closed I usually loose 15-20%!!! I disables Facebok app but nothing, Battery is still draining!

have you done any changes in the wifi setting stated in this forum http://forum.xda-developers.com/showthread.php?t=2378862
i have also made the changes and after that the battery drains like hell

No I didnt done any changes to wifi settings because I didn't have any problem with my Wifi!! I just clean cache on Eco Mode and I will see how battery is going!

i had peretty gud battery life , about 6-7 hrs of sot with wifi on all the day and lots of whatsapping . but now somehow suddenly stamina mod stopped working and getting lots of awake by whatsapp even it is greenified

Same problem here
Xperia SP battery backup is fine when i am using it. But when everything is off and stamina is on at night, i usually lose about 25% of my battery with cellular on overnight !!! But in airplane mode, stamina mode works fine. Only 0%-1% battery drain overnight. I didn't exclude anything in stamina mode. And i always keep my mobile data, wifi off when sleeping. I also checked battery stat but nothing is out of ordinary. But i think cell standby is consuming the power as everything is normal in airplane mode. But why do this happens to me when so many others are fine with cellular on? And the question is, how do i decrease the excess battery consumption by cellular mode when cellular mode is on and mobile data is off? It doesn't make any sense. Any solution for this weird problem? Help me please, this thing is driving me crazy. It takes more then an hour to charge 25% I am not rooted, bootloader locked, completely stock .205 and i have tried flashing and restoring via sus but nothing works. I even formated my internal memory and sd card I am using Xperia SP for about 10 months and stamina mode never worked for me :crying:

Alright i have sorted it out kinda... When um using settings -> GSM/WCDMA, the cell standby keeps draining battery. But when i select GSM only, the battery doesn't drain, lost only 2% over night with stamina on. But i ask this, how the hell am i supposed to use 3G data when the GSM only setting is selected ? Also another thing, the phone is intended for USA market(the customization is customized US). I bought it from Bangladesh and using in Bangladesh. Does this battery drain has to do anything with different Baseband version maybe ? I don't really know anything about baseband and stuff, just a guess. Anyone can help me in this matter ? Shall i flash an Generic INDIA rom ? Because Bangladesh is located besides India...

I have the same problem, maybe its a wrong baseband?

So I need to know can I flash only baseband from 4.1 ftf over 4.3? Because this problem is never exsisted in JB 4.1. :good:

My question exactly. Look at my post (up). My XSP is made for usa market and i am using it in Bangladesh. Maybe that is what causing the battery drain when i use WCDMA/GSM and WCDMA only. But in GSM only, battery life is fine. Not even a single percent battery drain over night. Very huge difference. Now i am downloading a generic indian .ftf to check if it is because of different intended market or not... I will let you know as soon as i am done checking...

I think you can do it as soon as the both rom(4.1 and 4.3) are intended for the same market as the one you are using right now... Because they both will have the same baseband i think. But then, it would make no sense to flash the same baseband. I am not sure though. I am not a developer. You better check with some expert before messing around with baseband....

Yeah, im using an european modded rom on a latinamerican country. Will try New baseband as soon as i have some spare time

Battery drain issue with new Xperia SP

Hi,
Its been a week since I bought the Xperia SP. The phone came with 50% battery with an estimated standby time of 2 Days. Now, the battery discharge really quickly. With a 100% battery it lasts only for a day (Estimated standby time of 20 Hours). Well I only listen to music on my phone. Brightness is kept at 1/3rd level and mobile data and wifi aren't used at all. I do a little bit of casual gaming. Subway Surfers , to be more precise. That's all. Also when you switch on / off the STAMINA mode, it doesn't effect the battery life. Estimated Standby Time sticks to what it was before switching on the STAMINA mode.
I need help in order to resolve this situation !

Read before you make threads.already many threads about battery life of xsp
For the stamina mod problem do this
Settings>apps>all apps>eco mode controler/extended standby mode controler.
Clear its data and reboot.
The stamina mod should work fine now..do this whenever you find the stamina mod buggy
Hope i helped u

Man.. don't keep saying this like theres a bug with stamina mode.
It's not a bug, the reason his stamina is giving same estimated standby is because stamina is not making a difference, clearing data won't change this....only hide the problem for another few days.
Instead we should try find why his battery life is not good but from my experience this won't be easy... I think there's a problem with the xperia sp's stock rom causing fast battery drain.
@Gamer R - First thing to do is check battery stats for an obvious case. If there isn't one my best recommendation is to restart the phone. This can reduce the battery drain for a couple of days, sometimes restarting doesn't help though.

It might work for you.. but in OPs case it clearly isn't otherwise his estimated standby would be different with stamina enabled.
The phone does calculations related to your usage/battery drain to work out any benefit from stamina, if there is no benefit it won't report better standby time. Clearing data resets these calculations and nothing more...it wont fix any problem so there's no point in resetting them.

Anyways i dont want to fight with you on this...i helped him with the solution which worked for me...estimated time resets when you clear the data.clearing data is a temporary solution.

Okay
I think he wants a real fix though.. maybe you should give a disclaimer saying that its temporary and only fixes the estimate, not the drain

@spix123 & @dipesh1502
Well clearing data of Eco Mode did help in fixing the Established Standby Time. Time to test it whether is it being accurate or not. Right now I have 14% battery left with an established standby time of 16 hours.

Clearing the data cant possibly have any benefit to battery life, I have a similar problem to you and already tried it several times. If it appears to improve battery life then its just the restart which helped (assuming you restarted)
Right now your stamina mode estimate is not accurate, it takes a few days for it to correct the calculation as all data has been cleared.

I've had an estimated standby of 9 days before but chance of that happening is zero
I got this by having over 4 days on battery without using stamina mode then enabling stamina showed 9 days. This was a fluke though.
What is your battery life like? How many days and what usage?

For me Its about 3 days. Some calls. Some angry birds. At start Stamina Mode shows for me 9 days. But stamina mode mod keep data of usage and analyze them. Thats why after some days Stand By time is reduced. Clear data from stamina mode, it will show about 9 days. Don't use (really dont) your device and it can be possibly to make SP working 9 days. WHen I charge my phone in evening with stamina mode on in the morning (after 9, 10 hours) i still have 100%.
And hundert of times. There was a lot of Threads about battery for Xperia SP on this forum, and reeeeeeally lot threads about battery life in Android at all. Just use SEARCH option.

Are you using stock rom? I know the SP can have good battery life on custom roms.
I've searched through all the threads and none of them helped my battery problems at all so I can understand why OP made another thread even if he saw the other ones.

Yes Stock. But today I will change to existenz mod.

Do you have anything disabled? I don't see how you can get that battery life on stock rom. I've factory reset, tried airplane mode etc.. nothing works, battery just keeps draining mysteriously.
100% after unplugged for 9/10 hours is just impossible. Even when my battery decides to drain slowly it will still lose 5% in that amount of time with no usage.

I have just disabled/uninstall pre installed operator apps, and some stock apps. Turn off bravia engine and gloves mode. And - I use 2G Network only - 3g or LTE Network cant hold battery so long. More traffic - more battery drain.
I use my phone at about 3 months and it still hold 100% during night after full load. More. When I wake up my device in the morning it still have percentage of battery which was when my XP went to sleep.
Stamina mode of course ON.

We have (had - I run eXistenZ now) same software. Some people have this issue some not. I think this is hardware problem. Some batt can be better than others. Its like with for example CPU for PC. Some same models U can overclock a lot, and some make reboots after few steps.

[Q][Resolved] Why does Xperia V battery last so much longer than T/TL?

In the year I've owned Xperia TL (LT30at), I've never been able to get a full day of use (12-14 hours) on one charge except for one week when I had to turn off the data connection (ran out of data allowance). I keep Stamina on at all times but BBS reports at least 3%/hr drain overnight. When the screen is on, the drain increases to 40-50%/hr and that's mostly on auto-brightness, which is minimal indoors.
At the same time, I see posts claiming that their V's are getting good 20 hours of total battery life, which includes 3-4 hours of screen time and minimal drain during inactivity. I understand that the V has a slightly smaller screen and 3G radio, but I can't fathom how that could account for such a difference in performance.
Can someone explain what differences I'm missing?

First things first. Have you compared your XTL's battery life with other XTL users? Or just maybe there are rogue apps sucking every bit of your phone's juice. Check with BBS or Gsam Battery Stats. And again, different people use their phones differently

Interesting. With my TL (lt30a Bell unit though - not AT&T unit), I would get a full day out of the battery, whether I was on stock PL 141 (JB), or the stock AT&T rom (which I think was also JB). Only thing I did on either rom was root/CWM/remove bloat apps manually.

BBS always says the biggest resource hog is bam_dmux_wakelock, which I think is related to wi-fi based location because it disappears when I turn off location. Overall, No. 1 and 2 battery suckers are Android System and Screen.

That 3-4% drain in standby has always been there regardless of the ROM. I recently tried a stock-based 4.3 ROM that was draining 10% in standby - that was clearly fixed by another one.

But your phone needs way too much battery when the screen is on, you could eiter try to uninstall all unneeded apps, deactivate gps, nfc etc when you don't need it, or reflash the rom..

My standby drain with Stamina is about 3.5-4%/hour. Is that normal? Compared to the screenshots of XV I've seen around here, it doesn't seem right. On top of that, Stamina app keeps on telling that the phone should last for about 15 hours or 24 hours on standby.

As said before, that also depends on what apps you have installed, and how you've configured Stamina mode, but your bigger problem is your screen on time, 1 hour is nothing. So you should try to reflash the rom. But before you do that you could ckeck the battery, you can find out about your battery health at the service menu

I get straight 2 hours from 100% to 0% of screen with minimal brightness. Also, the unit runs extremely hot when the screen is on.
Battery health is "Good".

This means it is a software problem. Reflash the rom, and wipe all your data. Roport back when you've done this

LTE: On (of course, but mostly auto switches to the wifi)
NFC/GPS/WIFI: On
Bluetooth: On twice a day (when I use NFC smart tag in the car)
Brightness: Always Auto
Google account (sync always on)
Exchange account (for work emails, always on push)
WhatsApp and BBM accounts
I don't have any old screenshots of my batt. usage, but this was a usual day for my TL:
Unplug from charger at 8:30 a.m.
Glance at work email
Go to car, NFC tag to turn off wifi and turn on Bluetooth
30 mins later, NFC tag to turn ON wifi/turn off Bluetooth
Moderate use throughout the day: occasional whatsapp, bbm, texts. Work email if I'm not at desk, imgur 5 mins, instagram 5 mins, xda premium app for 5 mins (a couple of times a day).
Go to car, NFC tag to turn off wifi and turn on Bluetooth
30 mins later, NFC tag to turn ON wifi/turn off Bluetooth
At home, battery is likely at 55%. Nothing but occasional whatsapp/bbm/texts usually for the evening. By 11:30 p.m. it's pretty well dead at 15%.

Yes. Precisely. I don't understand how nearly identically hardware (the biggest 2 differences being LTE radio & slightly larger screen in XTL) result in half the running time off the same battery.

But dude, the problem is not on XTL in general. I think your phone has some hardware problem. Was the battery life with the previous firmwares (4.0 and 4.1.2) as bad as the recent build?

It has been like that all the time. I realized something was wrong when people started posting significant battery life improvements in 4.3 ROMs and mine stayed the same.

Is the V battery life sufficient for you guys? I've always thought it's a little bit of a stretch if I used it even moderately - I use my V as a hotspot for my Galaxy Note 8 most of the day, and it can barely survive until the afternoon.
That's one of the reason I have been debating getting a Galaxy Note 3 for the extended battery life.

Too Much overnight Drain

Guys i am experiencing A high amount of overnight battery drain.Almost 15% battery gets depleted every night.
I am on OOS beta 10 with Ex Kernel... Android OS always consumes 13-15% battery..
Can anyone provide a solution ?

It might be one of your apps that keeps waking the device overnight. Get a Wakelock detector, look for the app that might be the cause, uninstall it and see if it helps.
It might also be the kernel I'm not sure why but EX was draining a lot of battery for me as well, but it seems to be working just fine for others. So you might also want to switch to stock kernel for a bit and see how it goes
Also, a bit unrelated, but putting your phone on Airplane Mode while you're asleep can help also. (IF you don't get any important messages or calls overnight that is) I lose no more than 1-2% over 8 hours on Airplane Mode. Plus, it's good for your health as well.

Airplane mode didnt help....
Wakelock detector didnt show any specific app....
Maybe EX issue....but why dont others have this issue ?

I'm not quite sure about that. I only used EX once. Once you're certain that EX is whats causing the drain, you can go ahead and ask in the EX Thread. Hopefully someone will be able to point it out. And if you're not certain, I'd say flash stock back and get only the apps you really need and see if it still drains.
And if you're in to custom business, I'd suggest you try out Paranoid Android once as well, the new build is pretty solid and i'm getting a considerably better battery life than i did on OOS, both active and idle

I'm losing 1% per hour, it seems normal for this device.
I've tried factory reset and various kernels.

SultanXDA CM13 is giving the least idle drain with this device. Rolled back to M for now, until i get best battery performance N ROM on this device.

Massive battery drain before and after wipe

Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.

i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.

Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..

battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.

Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery

Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now

i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time

After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help

i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
