You mean you have LTE data connection on all the time?

Battery burner.

GPU 300 Mhz, CPU 1450 Mhz (but this is least influential), data connection on only on demand, wifi only on demand, brightness range from 40 - 100 % (auto-adjust by a 3.party program), stamina on 100 % of the time (Low battery mode are off, location based Wifi is removed from my system at all).

I concur with you, it seems there is one program or service on your system which drains the battery.

I personally do not use better battery stats, or anything else like that. To my opinion these programs are less helpful to useless. I also do not use any automation. I like to do things by manually, by hand. That ensures I have control.

I would start with the very own build in system settings -> apps and see what is running there, and how high is the memory foot-print for each app displayed. My second course of action always is looking at Wakelock Detector stats. Anything else than the Android System with more than 100 wakelocks in 8 h needs close examination.

[Sony Xperia T, TL, TX, V] peter-k:
You are entitled to your opinion.

I also don't like Greenify. It's prone slowing down the system. It's harder to swim against the stream than with the stream, right?
[Sony Xperia T, TL, TX, V] bsined:
System Settings -> Apps had very a modest list. Moreover, I was using Xposed GravityBox's RAM bar to check RAM usage on clean install and after all programs and found out very marginal difference (50-100MB).

BBS shows all wakelocks (even better than Wakelock Detector). I was able to narrow it down to too many alarms being sent out by com.sonyericsson.android.wakeup, which is the service for Fast Dormancy. After some searching around, I found a definite fix to disable it. Based on about 2 hours of testing the various conditions, battery life seems to be as good as when the phone was freshly reinstalled.

If I have free time, I'll look for the culprit that needs the network so badly (I did disable nearly all notifications but I have a few dozen apps that need network access).
[Sony Xperia T, TL, TX, V] peter-k:
Good on you, and thanks for reporting back! :good:
[Sony Xperia T, TL, TX, V] Gasai Yuno:
I respectfully disagree. My LT25i survives much longer on LTE than on HSPA+, even despite LTE being at around 1-2 bars tops and HSPA+ being full bars.

“Battery burner” applies to 1) older transceivers like in Verizon's Droid Discharge, 2) constant mobile data flow. An idle MSM8960 LTE transceiver requires less power than its HSPA+ counterpart.

My phone only enables Stamina at 30% and battery saving mode at 15%; in pure standby it lasts 100+ hours on a single charge with LTE and Wi-Fi enabled (GPS usage allowed, Google Location Reporting enabled) and with Twitter, Plume, Google+, GMail, E-mail and LINE syncing automatically. Screen with maximum brightness set to around 35% (perfect for indoors use) and automatic brightness control enabled eats 10-18% per hour; with brightness limit raised to 100% and automatic brightness enabled it consumes 15-20% per hour. Yes, that's on 2600 MHz LTE.

Although battery does drain fast if I'm in an area where there's intermittent LTE coverage and the phone has to rely on 3G.
[Sony Xperia T, TL, TX, V] Antiga Prime:
It is harder to swim against the stream... but I don't know what that has to do with anything. I think you actually don't realize you contradicted yourself, so I'll explain. The functionality of BBS is practically exactly the same as Wakelock Detector, so saying:

And then saying...:

...is a contradiction. If you think they are "less helpful to useless", why is your "second course of action" to use Wakelock Detector? If it's useless and less helpful, why would you even do it? And, this isn't my opinion, it's a fact.

I didn't make up any of those quotes! ;)

Guys, guys, be cool. We're all cool here, aren't we? Are you cool? I'm cool. Be cool... ;)
[Sony Xperia T, TL, TX, V] peter-k:
WE are all cool and that is how I understand things from my end.

I tried both. BBS causes wakelocks in itself. Wakelock detector causes nothing and has no memory foot-print until stats are viewed. Thanks for your expertise explanation. Though may be others will benefit.

Well at least BBS has a very useful function that benefits users. So actually what I really had in my head were all the battery savers, etc.

Sorry for diversion from the OP, my only apology is the original problem has been solved.
[Sony Xperia T, TL, TX, V] davidsteele1975:
I deviate between using a power manager and doing it myself. I see advantages in both. The better power managers are usually inside a few percent of doing it myself, but the difference isn't significant in terms of days of use. I'll squeeze a couple of days from my device with minimal use depending on the solution I have, but I'll never stretch to three regardless of how I do it...

EDIT forgot to add:

...but occasionally can misbehave and either keep stuff turned on, turned off or require a device reboot. Not the end of the world of course...

This thread's old now but I said I could post my battery life since I use the phone daily. My usual is around 2.5 hours of screen-on-time, which is pathetic compared to the 5+ hours my xperia sp used to get me. There are times I'm thinking about getting a new phone because of this. I usually watch lots of videos on the phone. The screenshots here were from heavy browsing on wi-fi. Wi-fi was on at all times, just like stamina. 5-6 tabs on opera. Also, here are my c.p.u. settings:

Minimum c.p.u. frequency: 192 mHz

Maximum c.p.u. frequency: 1512 mHz

[Sony Xperia T, TL, TX, V] peetr_:
Just to show you the real heavy usage battery life (it's nothing special - like other smartphones).

Evening - night (sleep) - morning.

Everything turned on - 3g (low signal), wifi, sync, Talk, gps, bluetooth, about 80% of brightness, because autobrightness is crap, 82 apps installed (some of them with notifications), but many stock apps uninstalled. I was playing Air Attack HD for about one hour and the rest was browsing with Tapatalk , some music, some benchmark, etc.

Btw do you know, that the cpu thermal throttling lowers the frequency to 1GHz on 40C battery temperature? Seems a little low to me. Something like 1,2 GHz would be enough.
[Sony Xperia T, TL, TX, V] LegibleEel:
Few images of my battery life, everything stock no mods, 3g always on, tethering on for around 2 hours, around 1hour of music and games. WiFi on when I get home which is around 5pm.

I'm finding my Xperia T to be... indifferent. I'm seeing maybe three hours of screen on time to a full charge, which I'm a bit disappointed with. What I'm finding is that network activity seems especially inefficient. Android OS / Android System appear high up on the list. It reminds me of my early experience with a Galaxy S II...

You guys are making me very happy. I am coming from a Thunderbolt and often have to charge my phone in the middle of the day and will have it almost die before I go to bed. I ordered my phone from Clove and have to wait until the end of the month for it to ship. Seeing everyone's screenshots is making that wait even harder!
[Sony Xperia T, TL, TX, V] LegibleEel:
This would probably be my last post with the battery life, I think the battery has finally optimized itself I guess. Average use, few calls around 20-30 mins each, lots of text messages, around a hour of music, and a couple of hours of internet browsing.

After issues I have written here: http://xdaforums.com/showthread.php?t=1943671

I have performed few things which I did in the past with my other android phones:

1. discharge the phone to 1-2%

2. charge the phone till 100%

3. switch off the phone

4. charge till battery full picture

5. power on, go to /data/system/ remove batterystats.bin

6. power down phone

7. charge till battery full

8. disconnect the cable, switch phone on

[Sony Xperia T, TL, TX, V] @rbiter:
So what is up? 32 posts and it is hard to glean how well battery life is from this thread. Need more screentime shots. Can't even tell how many hours screentime with battery life over a day. Just see screenshots of total time which is useless unless there is a screen time shot to accompany it.

...
[Sony Xperia T, TL, TX, V] masi0:
Why don't you test it yourself? This phone is capable to run on single charge between few hours till 2 or even more day depends of usage and configuration. If your phone is eating battery like crazy thats obvious you did something wrong.
[Sony Xperia T, TL, TX, V] @rbiter:
lol. i don't have the phone. i am considering it though. i am looking for a phone with better than average battery life. it is hard to tell what kind of battery life i am getting from this thread, which is supposed to be posting screenshots of battery life. i know everybody's usage is different, but with a few good screenshots from various users whose usage will always be different, you can usually glean what type of battery life can be had from a device. i am trying to figure out if it will get anything near 8 hours screentime with moderate use throughout a day. at the moment i get 4+ hours during the week and 5+ hours on the weekend with a galaxy nexus. the xperia t/tx has a smaller battery but also lcd screen with a 28nm soc. i am coming from a device with a battery hogging amoled, 2000mah battery and i believe 45nm soc.
[Sony Xperia T, TL, TX, V] peetr_:
I posted some screen on time screenshots. Basically I would say, the phone is capable to last about 12 - 16 hours with 3 to 4 (maybe 5 just reading something)(2-3 playing something) hours of screen on time. Average battery capacity with average holding time.

I have been using Galaxy Nexus too and screen on time is the same and maybe a little better.
[Sony Xperia T, TL, TX, V] @rbiter:
That's not very good. I was expecting a lot better. I saw your screenshots and you have some serious wake issues. And it might be that app you have running in your notification bar tracking cpu usage. I get 4h+ on my nexus no matter what I throw at it, and over 5 easily on WiFi and I've got over 5h a few times on hspa only. I was hoping the t/tx got 8h, but realistically at least 6h out of the box. I don't even think a good custom kernel can make it 6h if your case scenario is similar to other users.

Here is mine..
[Sony Xperia T, TL, TX, V] @rbiter:
There is no tale to tell with that. We need screenshots of screentime. You do that by tapping screen on that particular page. And we will better data to extrapolate from if batteries are run down at least 50% and show both usage screenshots.

I am probably the only one that sold brand new xperia T in just 4 days. I gave it 4 cycles and I think the battery was a disaster. It lasted me from 9 AM till 12:30, I have not had any phone before in my life with such a bad battery. All else, top notch, but battery disaster.

Going back after a week!

I have had the phone since Saturday,

I previously have a iPhone 4 and really had no issue in moving until recently playing with my girlfriends Samsung S, where I dedcided that even with my Jailbroken iPhone, I needed more freedom to do as I want.

I know 2 people who have Xperia S's and the one word they say is Battery. Don't buy a Sony phone.

I have always loved anything Sony so I ignored amd did as I wanted.

Now my iPhone 4 is exactly 2 years old now yet can hold a very decent charge, teh XT sadly cannot.

On Monday, it was fully charged for work, alarm went off at 6.15am, put it on 10min snooze for a couple of time and then listened to a Radio app with the screen off.

Listened to some music for about 10min through the Walkman app and by 12.30pm the battery was down to 1%

As I said, this was Monday.

To me, the battery saving methods do not make any sense, why should I monitor my Active Syncs, turns this and that off.

Dim the screen so dark that I need Supervision just to see things and yes, I have tried these methods to see if there is any improvement but the fact is, the battery drains regardless.

I am not an iPhone fan boy and I also have a Blackberry 9900 that I use daily so I know how Smartphones can use more battery than previous conventional phones but this is appalling. I am returning the phone on Saturday pretty much for a refund.

This really does not live up to being a Flagship phone and is really a big let-down in my honest opinion.

Right now the bat is at 42% so I could say that there has been an improvement perhaps since Monday.

The talk of the JellyBean bringing better performance is one too many months away, what do people do in the interim.
[Sony Xperia T, TL, TX, V] masi0:
really cant believe that it is a fault of the phone. problem with complaints and android phone is because some people how no idea or experience of how to work with this device.

iOS is idiot proof system and limits things that can be done. would recommend to look what have you done, what apps you have installed and then sort it out.
[Sony Xperia T, TL, TX, V] francef:
Hi,

I previously worked for Carphone Warehouse for 10 years so I saw the birth of the Smartphone. I have always brought PDA type phones when they used to be called PDA's. I've had phones from before Sony joined forces with Ericsson and phone after they did there merger.

The simple fact is, you have to jump leaps and bounds to simply have the battery last a 9-5 day at work (not including the daily commute). I drive to and from work by the way so I am not even using it to kill time ie, playing games and listening to MP3's

Battery is down now to 39% and I've not touched it since writing the last message.

(No Apps running in the background apart from the default Sony ones).
[Sony Xperia T, TL, TX, V] AvRS:
Sounds like serious wakelock issues for it to die that quick. Search for betterbatterystats available in the main forums and you should be able to see what it is causing it but I've never seen a phone die that quick. My Galaxy S2 has a smaller battery then the Xperia T and I listen to 2 hours of music a day and do the odd browsing etc and still end the day most days with over 50% left. Can only see the Xperia T being better which is why it's on the list to replace my current phone. Majority of battery issues are userspace (user setups, apps, services etc) related.

I use all my phones the same, as you can read a few posts after me, there is one other fellow with the same problem, maybe even more.

I buy and use phone as a tool not as a gadget.

I really talk a lot, nature of my business and I always have push mail on. Everything else, believe me, I have no time for apps or whatever is there.

I gave it a full week, started friday, but counting from monday. The battery should work out of the box at least in a week. Sold it while it was still hot, getting my investment back.

Next on my list will be motorola razr maxx hd I presume. 3300 mAh battery.

- Email count in push mode.

[Sony Xperia T, TL, TX, V] davidsteele1975:
With my Xperia T, I found that WiFi was very power efficient, Bluetooth not so bad but 3G was nasty. Not sure if it was because it was also very fast over 3G, but it chewed through battery.

I also never had the alarm manager issue.

@guims78; it's impossible to quantify. I'd expect to see a working day from that configuration, but "it depends." I was seeing under three hours of combined screen on and talk time if I used 3G and closer to four if I used WiFi.

[Sony Xperia T, TL, TX, V] davidsteele1975:
If I had more patience, I'd wait it out, but with Jelly Bean a stretch away until February and there's no guarantee Sony will refine the modem / baseband / whatever they need to do reduce 3G power consumption.

Lovely handset, though...
[Sony Xperia T, TL, TX, V] francef:
Hi there guys. I gave the phone till yesterday and still saw no improvement to the battery life as much as I would have liked it to have been a sucess.

I finally returned it and after much research and after many a review read I have purchsed the Samsung Galaxy Note 2.

Can literally after just over a day see the vast improvement in terms of the battery.

Just hoping that Sony actually get their acts together and release a Flagship phone that is worthy to challenge the other top manufacturers.

[Sony Xperia T, TL, TX, V] babylonbwoy:
I can see in the screenshot that your battery is at 1%. With Li-Ion battery it's not recommended to go under 5%, some says to always charge the mobile when it's between 10/20%, otherwise you can lost about 20% performance (up to 40%).

Do a little search on google to confirm.

That said, I'm really satisfied with XT battery compared to my XS which drain as hell and is always in activity (no deep sleep, even at night in plane mode).
