Where are you found you stock ROM ? Locked BL ? Really fixed your battery ?
[Xperia SP General] mrjraider:
I used Sony Update service to reflash my stock rom. Yes my Bootloader is locked.

I also made a small guide how to use SUS:

erm.. there are two options.. One is Upgrade or something and other is factory reset with upgrade..

so either way i'd be taken to latest firmware available? right?

I dont want to flash latest firmware as there are some issues with it..:confused:

When I'm out (about 10h everyday), my battery is able to withstand 2-4 days with music on when travelling, LTE on when I'm out, WiFi on (Switch to GSM mode) when at home before sleep. Impressive indeed.
[Xperia SP General] SunnyChrono6:
I was just going through this thread, and the people who've gotten 4-5+ days have recharged their phones in between. So nothing is wrong with the people who've gotten "just" 2-3 days :P
[Xperia SP General] ashis.kyal:
My Battery stats For the whole day.

Used wifi and bluetooth For headphone also.

Its good now
[Xperia SP General] chewlohseng:
Mine too. Can even withstand about 2-3 days even with LTE on when out. Unlike other phones manufactured by other manufacturers (erhmm Samsung) which pumps in a larger battery but lasts worse.
[Xperia SP General] ashis.kyal:
Have a look at the stand by time!!
[Xperia SP General] anthk:
Is it normal to have 1.4% / hour drain at night with wifi/data off and stamina mode on?

The default battery info showed awake period for like 1/3 of the time but my betterbatterystat says my phone was in deep sleep for 99% of the time.

Which one should I trust? It seems the bbs is in the wrong here because i had no problems with awake time when i first got the phone and the drain was minimal at night
[Xperia SP General] chewlohseng:
No, it's not normal for the battery to consume >1% per hour in Battery STAMINA Mode with network connections off. Upon installing BBM my battery drain about 1-3% per hour without any use too. Very annoying, I uninstalled it two days after I installed it. After that battery is running normally again, back to 2-3 days per charge w/out any problem.:good:

This is my phone's typical battery life (two different occasions). Battery only drain 0-3% over the ~8 hour overnight period.:laugh:
[Xperia SP General] Jambu95:
my xperia sp sucks, my phone with everything turn off, gsm only, no wifi, no bluetooth, no gps, screen brightness lowest,

no apps installed, less than 1 minute on screen time, no sim card, standby time is only 2 days until the battery reach 0% from 100%

Help please, it's already half a year i had this problem, and why no people or any helper on this forums wants to help me out?

sony service centre stated that "standby 2 days without using it with no sim card is normal for all smartphones"

my warranty card now is trash, feel like crying and throw that **** away
[Xperia SP General] mrjraider:
What on earth is happening. It is getting worse
[Xperia SP General] chewlohseng:
Dear Jambu95,

Maybe the problem is due to the fact that you do not set your phone to airplane mode. As there's no SIM Card in your device, the Sony Xperia SP will constantly read the SIM Card tray to see if a SIM Card is connected to the device or not.

Try to use your phone in airplane mode and see if your device is able to withstand or not.

Cheers!

Dear mrjarider,

BBM is the cause of constant draining of the battery in your C5303 / XSP LTE. BBM keeps on running will lead to Battery STAMINA mode to not be able to run. The awake times is about 90%* of all time. The HSPA+ data connection is another reason why (if you never switch off the data connection before letting the device go into sleep mode, battery would drain quite alot).

Hope this helps. Cheers! :)

*Edit: Awake times seems to be in the range of 90%, not 80%.
[Xperia SP General] mrjraider:
Many thanks i will give it a shot :)
[Xperia SP General] mrjraider:
Like wtf!
[Xperia SP General] sebeqone:
That's my first Sony phone, must say that Stamina mode works great. It is a spare phone, so practicaly no usage, maybe 3-4 calls, few smses and few minutes in web browser but please look at the standby time :)

BTW It is custom ROM, based on xperia z framework.
[Xperia SP General] chewlohseng:
Wow, that's mind blowing 9 days.:cool: You mean the eXistenZ Ultra ROM?
[Xperia SP General] sebeqone:
Yes, this is eXistenZ Ultra ROM but I had similar results with stock rom :)
[Xperia SP General] chewlohseng:
Actually it's expected, since the power saving for both stock Sony ROM and the eXistenZ Ultra ROM is identical [Battery STAMINA Mode].:D
[Xperia SP General] dipesh1502:
Got screen time of 5h 30min on existenz ultra rom till battery was 1%

Usage(stamina mode on)-

Whatsapp

40min video

Used 3g and wifi both

Walkman for 45mins

45 min gaming

Things i did-

Removed all the bloatware

Clocked the cpu at 1.2ghz
[Xperia SP General] mrjraider:
For those who want to get the best battery life. Dont uncharge your phone tot 5% or lower this is bad for the battery..
[Xperia SP General] chewlohseng:
Don't we have to deplete the battery every few months to get the battery life recalibrated by the software? :confused:
[Xperia SP General] skojevac:
battery life of XSP is truly mind blowing. here is what I got after several days of lite usage.
[Xperia SP General] skojevac:

Dont know wats wrong.

Evn i am unable to see picture in themes and apps sectn:(:-/
[Xperia SP General] skojevac:
seems like whatever it was it got fixed. anyways, I can't help but to brag about it... 11 days and 10 hrs is pretty impressive battery life for any smartphone :D
[Xperia SP General] spix123:
That is just the estimate...
[Xperia SP General] skojevac:
yeah, I know. turn on wifi and it would go down to few hours right there. but it's fun to see this anyway. ;)
[Xperia SP General] Robin>Hood:
More is even better, li-ion battery cells get damaged when completely discharging. I myself almost always charge the phone when its somewhere between 30-40%.
[Xperia SP General] jonmorris:
I wouldn't worry too much. The chip in the battery should stop it ever getting too low to do damage.
[Xperia SP General] Adpnt:
I would hardly call "mind blowing" 1-2 days with moderate to low usage.

Mine eats the battery alive when browsing internet even though I am 5 meters away from the WIFI.
[Xperia SP General] raziel123:
Screen on time

You should be able to get about 5 hours screen on time with wifi on,

which is reasonable.

standby time is amongst the best though.

regards
[Xperia SP General] spix123:
Not on stock rom it isn't.

Very inconsistent. Sometimes I can only get 1.5 days usage with just 1 hour screen on time.
[Xperia SP General] saurabh808:
battery

i just get a day with wiifi on n my stamina mode seems to be not workin just after 3-4 days i purchased this phone
[Xperia SP General] dipesh1502:
Do this

Settings>apps>all apps>eco mode controller/extended standby mode controller

Clear its data reboot.

Should work.
[Xperia SP General] spix123:
That only resets estimate, doesn't actually improve battery life
[Xperia SP General] dipesh1502:
But for now

Thats the only solution we have
[Xperia SP General] adryanodej:
i use clean&tweaked rom too and i get about 4-5 days without wifi or data conection and with wifi always on i get easely 2 days. With other ROM`s i get 24 hour`s only.

That why I returned to Clean&Tweaked, hope Ali does a Clean&Tweaked version for 4.3 when it gets released:)
[Xperia SP General] saurabh808:
thanks

hey thanks it did worked
[Xperia SP General] dipesh1502:
Yeah

Do that whenever you

Find your stamina mod not working
[Xperia SP General] spix123:
All that does it reset the estimate... makes zero difference to battery life. It just tells you that you'll get longer standby but in reality you don't.

It's not a fix, just false hope ;)

The fact you need to do this shows stamina mode makes no difference to your battery life.
[Xperia SP General] b00b:
i use tethering on all the time as i need to...and sadly i get

only get 6 hours battery life

, dont use stamina as that disables mobile data when the screen is off and i need the mobile data on all the time :mad:
[Xperia SP General] dipesh1502:
You can add exceptions in stamina mod for which apps the data will be on even in standby
[Xperia SP General] b00b:
Thanks for this tip, only being using my xperia-sp for just about a month now so didnt know that, will surely look into that...and this just shows that indeed it gooood to talk ...as when you do, there are nice people out there willing to help and share their knowledge and positive experiences:)
[Xperia SP General] dipesh1502:

[Xperia SP General] raziel123:
Stamina Mode Puts the Phone into deep sleep mode, or at least longer in Deep Sleep mode and consumes minimal battery when the phone is on Standby.

If it isn't working, than the Culprit is likely the Rom you have installed.

on mine it works fine.

Have flashed the stock ROM and used Stamina Mode on to check out standby time, and your battery life during daily usage?

regards
[Xperia SP General] spix123:
I'm using stock rom with no extra apps installed. Stamina mode makes no difference to battery life, I have tested it extensively as I do nothing on this phone except try fix the battery problem.

It will improve battery life if you have apps such as twitter that push notifications all the time. Even Sony says this

"*Based on testing done with default settings, default accounts and applications for Skype™ and Twitter downloaded to the phone. The more applications installed, the bigger the effect of Battery STAMINA Mode."
[Xperia SP General] raziel123:
Ditto, thats correct ... It's supposed to improve Standby time, and I can confirm that it does,

it won't improve any actual usage (screen on) time.

whats your screen on time?

do you get 4-5 hours browsing time?

video playback time?

regards
[Xperia SP General] spix123:
I should have been more clear that it doesn't improve my standby time either. I have tested it thoroughly and it made no difference at all using stamina mode. But this is completely stock, no twitter or apps that constantly wake the device.

My battery problem is that the device keeps draining fast when standby with or without stamina @ 2-4% per hour. I have managed to reduce this several times to 0.5% but it only lasted a few days before going back to draining fast and I can't find the cause. I believe its a problem with stock rom.

When the phone is draining fast (which is most of the time) I can get just about 4 hours screen time using the phone often during the day. With light usage the battery will fully drain within 24 hours and only about 1 hour screen on time. It's very annoying having to recharge the phone every day even if screen on time is only 30minutes. My other phones don't have this problem.

When the phone is draining slowly I can get about 4 days standby and still have 4 hours screen on time with light usage. Big difference but I cant make it stay like this.

I noticed that in mediaserver writes CPU total 18min, Keep awake 2h3min, is that some drain, or it is normal, what writes in your use details ? Tnx :)

This is the screenshot, it sometimes goes up to 25% and 2-3h of Keep awake time, always second, after the screen, is it normal ? Happy New Year guys, all the best :)

I got this phone last week for Christmas from Amazon and it was brand new. Haven't root it or touch anything involving the hardware so it's pretty much still in factory condition.

I came across this thread and also have some questions in mind. Because sometimes I would see the battery performance is amazing (only on certain days) that the phone would drop about 1% after 2-3 hours of standby. But more often than not, the phone battery drained itself during the time with as little usage as checking the time, sms, and stuff. So is it something normal?

---------- Post added at 11:12 AM ---------- Previous post was at 11:08 AM ----------

as long as at least once a month you let the battery die completely it will last a long time, plus don't always keep it on charge and use it at the same time. I've been doing this with my iPhone 4 and battery life is still great so im not concerned i don't think you should be too
[Xperia SP General] samsonslatebook:
I thought that it was better to let the phone discharging to 0% and then charge it untill 100%.. Any studies or infos about this? Also is it bad to let the phone on charge after 100% for a few hours?

[Xperia SP General] Robin>Hood:
Just google the difference between charging/draining NiMH or NiCd batteries and li-ion batteries. Then you might learn something and understand the whole myth about letting batteries of electronic devices drain completely.

I think that is a big problem in general with people, they think they know stuff, but thinking you know something does not say anything about the validity of your knowledge.

People believe things because they heard about things but they do not check things and therefore people make the mistake of 'thinking they know things' when what they know is not what is true.

This is the normal battery life of SP, screen never even used. It can be improved by restarting but only temporary fix, it will start draining fast again if you update an app on playstore or just by random.

[Xperia SP General] Th3Duck:
Your wifi is probably the problem of draining the battery looking at your android system percentage. This means the router constantly checking if your phone is still connected to wifi and waking the android system and draining battery. Have got the same problem on my girlfriends wifi. Havent got this problem on my own wifi at home, depends on the router. Havent looked for a solution just google it :p.
[Xperia SP General] werk91:
This is my 2 weeks old Xperia SP unrooted and unlocked. Last 2 days it was moderately used with data off on most times, Wi-Fi on for most of the time. Its not bad but overall I think my old Xperia J was lasting far far longer. Screen time 3h30m which is not impressive. I listen to music for ~ 2.30 hours a day as well.Wi-fi running is 1d 2h according to phone. I don't always keep the stamina mode on (only when using 3g). Glove mode is off and Bravia is on. All in all its a great phone for the price. I love it. Hopefully 4.3 will give me a little bit better battery, that would be awesome.

P.S. Those screenshots look quite bad is that normal ? ;D
