Hi, I've got another question about T3.
I saw, that battery outside (temperature about 5-10 celsius degrees) decreases drastically. For example, while I'm using my Xperia about 10-15 minutes with 3G (I'm not using LTE, no usim user there ), battery may fall even 20%, what's annoying me a lot.
Some advice about how resolve this issue?

What is everyone's cell standby battery usage, percentage wise?
Mine is 41%, which seems a bit much.
My battery is down to about 30% in about 6 hours (most of which was in standby).
I'm trying new roms and kernels, so I'm trying to determine whether or not that's the problem.
Today mine is around 34% and I have seen it as high as 41%..After almost 13hrs still at around 65% battery but I've been light on my phone today.
I've been incredibly light on my phone today.
When in some of my classes, I have horrible/no service. I'm thinking that has a lot to do with it.
Are some ROMs or kernels more heavy on the battery when not in service than others?
With my stock rom and kernel, my battery didn't last long, but it was much better than this.
Im usually about 41% also seen as high as 43% but only once....as long as your time without signal is low I don't think its that big of deal..but, if they is a way to lower it without goin into airplane mode would that help battery life?
Well if you guys' cell standby usage is as high as mine, then I guess that it isn't the problem.
I was just asking because it seems like I remember hearing that some phones increase Tx power when they don't have service in an attempt to get a signal.
Mine cycled through 1 bar, roaming and no service for about 50 minutes while in class today.
Maybe I'll just try different ROMs and kernels and find a combination that works for me.
~7 hours of use isn't cutting it since I was getting significantly more time with the stock ROM.
Thanks, guys.

A typical battery usage in standby with only 3G on (mobile data always on = off, gtalk = signed off) should be between 1-2%. In 6 hours of standby, you should not have lost more than 6-12% of battery charge. A full charge should be sufficient for about 3-4 days of standby.

He is not talking about the same thing we are.......he is talking about actual battery usage via battery icon, not the settings, about phone, battery, battery use screen.
I get approx the same battery use few % an hour with phone standby @ 43% of total battery use as long as I have a good signal and not using the phone
Two different things dont get confused.....
JuiceDefender has done the trick. I'm at about 45% battery remaining 8 hours and 2 minutes after being unplugged with 35% of the damage attributed to cell standby.
The only caveat is that Gmail and Google Voice don't push instantly. Of course 15 minute intervals are enough for my email, and a simple text upon receipt by Google Voice lets me know exactly when I get a voicemail.
Thanks all for your responses.
I don't get it, After 8 hours and 20 minutes of uptime, my Wi-Fi has a usage of 5% whereas Cell standby has a usage of 10% under battery use. What is Cell standby anyway and why is it eating so much battery?
I think thats pretty normal. My cell standby is normally at about 20% (little bit above WiFi). Well in the end it depends on what you do. If you dont use your phone at all, Cell Standby would probably have around 60% or more (relative values).
One more thing is, that these values are often wrong and nreliable. In my case Android System is always using 40-60% (cell standby around 20% and some small other stuff) no matter what i do with the phone, which cant be true because my battery life is quite normal. I just think, that these statistics are crap on some phones though i dont know the reason....
BTW: Cell Standby is just the normal communication between phone and GSM-Antenna, so that calls and messages can reach you. Its a kind of idle communication. Switching between bands (2G/3G) p.ex. consumes a lot of power in this respect....
Hi everyone.
I don't see anyone feeling bad about battery nowadays with new update. I dont see any improvement in mine :O
I need some informations from you, can you tell me voltage phone reaches when it turns off by itself? Its very strange when mine reaches around 40-50% voltage goes down very fast and it turns off around 3.2v...
Who's with good battery?
Tell me,
*phone time on battery
*display on time
*wifi time on
i feel like mine is not good i dont know the reason why.. my friend gets 7 hours of browsing(7hrs display on), and i get around 4... it cant last 5 hours with display on.
-- 30 % brightness, bravia off, sync off, auto rotation on --
I saw on internet some reviews 2 days of heavy use :O how?
I tried wiping batt. stats, and gonna try again after system creates batterystats.bin
i did it twice, but slight improvement...
regards
hope this isnt spam for you.
Hi
I have voted 8-9 hours for casual use at low display brightness 20-30%. Auto brightness is allways activated and using it in a fairly light room might increase your display brightness without you noticing this. Could this be the reason you are experiencing such high battery drain with display on?
Heavy gaming:
3D games like order and chaos and dungeon defender that utilize the Andreno consumes up to 30% per hour, that leaves 3 hours of use. Battery history show an allmost 50/50 between display power usage and the game process power usage. Buildin speaker also consumes allot of power.
FPSE that to my knowledge do not use the GPU but utilizes the CPU 100% consumes around 20% per hour leaving 4-5hours gaming.
Light gaming and casual use.
My daughters using drawing programs, playing angry birds or other light weight kids games plus some webbrowsing and email reading consumes about 12-15% per hour leaving 8-9 hours of use with dispaly on.
If you add speech calls on 3G your times will decrease significantly, this is consuming 20-30% of battery per hour depending on signal strengt. This is my personal observations.
Bravia is allways activated and I thought this was only used when watching movies or looking at pictures in the gallery?
It is interesting to read the SE support app installed and the SE recommendations to improve battery live. They mention that if your display is at max brightness it will not make any noticeable difference if you have bluetooth, wifi, data, sync etc turned on as the screen is consuming sooo much power at max they also recommend to use earphones instead of speaker to improve battery consumption. The rest of the recommendations are well known as to turn everything not needed off. The recommendation I like the most is a daily reboot to improve system performance
I like your review.. I got the same result with 3d gaming... 3 hours, but i never had 8-9 hours even with light usage.. Not playing 3d games..
Max. I get is 5 hours but i dont know how, i fell asleep on entry screen on asphalt 6...
Btw. Did u payed order n chaos i cant find cracked version.
3 hours phone on
40 mins display on
1 hour wifi..
Now on 85 %

I began to suspect it's from the battery it self, I reversed to the old firmware .145 the battery was the same, never completes a whole day, 19 hours maximum.
I think its battery too... I bought mine with world generic, and flashed uk generic, its same for me... Has anyone thought that somewhere in system is set battery capacity is example 900, i have read it on this forum in x8... So how to investigate it, my battery dies always ~4 hours display... It went once 2 days, and display time of course 4 hours.

Haha, a nice way of testing it, keeping it running while sleeping :-D 5-6 hours is probably more normal than 8-9 hours, that was when my daughters was using it with a kids drawing program at low light settings, it was not consuming much cpu at no sound was used.
I have bought order and chaos but had shortly installed a cracked version as there were some problems with android marked at the time. I paid for the game but it would not start the download, contacted their support and found a cracked version while waiting for them to fix it ;-)

I got some interesting stuff... I deleted mine bat. Widget, using battery calibrator i can see percentage, 4.2 v full, 3.75 v 46 %, i played 10 min game, percentage fell down, and now i got 35 %, same voltage... Btw. Stock everything.
And calibrated my battery today... I ll post in few days if i got some improvement, but i dont think so...
And 13 min 300 mhz, but display on all the time? Weird.
29 % 3.72 v... Browsing only
20% 3.708 v... Still browsing

The batterys voltage will drop allot from 100% to 90% and the voltage decrease will slow down as you are getting closer to 0%. I would guess 3,65 is close to 0%.
The battery % is not calculated from the voltage level but from an internal register in the battery chip that decreases with a value calculated by the battery chip from the exact amount of power used. The battery chip can measure precisly how much power is running to and from the battery.
The android calibration can change this register for example when the battery is getting close to a pre configured safe voltage level, could be 3,65v. It would then reset the register to 0 and the same goes when charging the phone.
If the register show you can have max 5000 units and you are charging the battery and reaches 95% and 4500 units while the voltage show 4,2 which is full, it would then update the register to have 4500 as max level and start to decrese this as power is draining from the battery. If you have 10% left and 450 in the register with voltage at 3,65 it will presume this to be empty and the register would be changed to 0 and battery indicator to 0%. The next charge to 100% should end up at 4150 which would match the exact capacity available for the phone.
The battery will over time slowly degenerate and its capacity will slowly decrease which is one of the reasons the calibration is needed to allways have it show correct battery levels.
The battery is actually not empty at 3,65 but draining it even further will drop the voltage and make the phone crash.
I hope my above explanation makes senses. Had earlier updated and compiled an android kernel battery driver for the old xperia x1 phone. I presume the mechanism for the battery driver in Xperia Arc is the same.

more results,
3.65v at 15%
3.6 at 8%
and since it passed 8, it goes down to ~3.25v but mine doesnt crash. it nicely turns off. 5 hours 35 mins display(yay.. improvement.), wifi time i cant remember, but 9+ hours. 30% brightness,around 30 mins total gaming, something like angry birds. 30% brightness. and like 20 mins 3g internet.

Interesting, the old xperia x1 could not handle levels below 3,65 6i
Hi,
I used the app Current Widget to manage my phone battery.
I just caliberated the battery an hour ago.
Now, when I turn off the screen and left it on standby for like 20 mins, I got the log report on the battery which said -4000mA (or something like that) every minute.
Is there anyway to improve this?
Thanks
Also, I have rooted my dvice to ARHD 1.2.3. For the last 10 mins, the log files recorded -4268mA constantly
I believe the standby drains aren't reading out correctly.. i have the same issue with battery monitor widget. Imagine with a drain of 4000mA constant the phone would be dead within ~25 minutes (as the capacity is 1800)
Yes, I think so too, hence I uninstall it and use battery monitor widget instead. Now it measures about 100 mA in standby. Is that normal for the One X?
Even 100 i think is a little high, because the companion core should kick in @ standby.. and that's the problem at the moment with the monitoring apps i think.. sometimes battery monitor is reading 4-10mA drain but sometimes as high as 1000+
Anyone have a worikaround for the network standby time. It eats about 30% of my battery daily.

That's a huge problem I think most of us are facing. Google needs to fix this asap
Most is pushing it. There was a thread on it recently and there was a real mix of experience. Mine seems to be between 7-15% most days for the 24 hour reading.
The percentage being high only really matters if you are not able to get through the usage you need. I am getting 24 hours of my normal usage (charging once a day in the evening before bed up to 80%) with it still being at 30-40% full.
Example thread on battery life at https://forum.xda-developers.com/t/battery-life-thread.4354977/#post-85942795
Various things have been posted about trying, such as locking to bands, but as random as the issue is as to whether you even have a problem, its random as to whether any of these workarounds do anything for individuals. All you can do is experiment.
I got about 9% mobile network standby in 24 hours, I should say though that I barely leave the house atm (homeoffice) and that means that ~ 23:30 hours a day the phone is constantly on standby, 4G almost never activated, so that's roughly 0.383 % battery drain per hour, I am ok with that.
Still I hope that Google can improve upon this.
