This is a post from the Xperia play forum about battery life. Since the new Xperia phones shares a common software maybe the Mini is affected too?

I'm gonna try and see if there is any difference for me on the sk17i.
good idea
nice, please let me know if there will be some difference for sk17i
thanks
well i tried it, and im sorry to say that ... but it doent change anything
Let me here give you and example of how bad is this phone battery situation is .
I have an HTC HD2 running android 2.3.3 and it has a 1GHZ processor which is the same with the xperia mini pro i bought , on the other hand the HD2 has 4.3" screen while the mini pro is only 3" so I already nticed after using the mini pro that its consuming so much battery than the HD2 but i wanted to be more specific so below are the details
HD2 Battery is 1230mA, xperia mini pro 1200mA ( Almost the same )
so I left both of them in idle for 8 hours ( wifi is on both have the same apps like facebook , google+, twitter, with the same update settings, )
the HD2 dropped from 82% to 71% in 8 hours in idle (Lost 11% )
The mini pro dropped from 100% to 50% in 8 hours in idle ( lost 50%)
for me this is a big gap between the two devices and to be honest i expected the HD2 to have a shorted battery life conidering its much more powerfull device and its 2 years old with the same 2 years old battery.
and i also noticed that during the test:
the HD2 never exceeded 10mAh consumption at all
the mini pro rarely went below 50mAh and the minimum was 26mAh
so i guess there is something that eats the battery during the idle time and it is taking alot of it comparing the two devices.
in fact when i bought the mini pro i wanted smaller device that will have a better battery life , but now its totally the opposit which make me confused.

Maybe very little actually.. but I'm gonna keep at manual.. no need to auto scan when I'm locked to one operator anyway.

I have been struggling a bit too with battery life. But with my current settings I have 21hours since charge and I'm on 65%. (so thats about 2.1% each hour) But thats not standby only. I have been using connectbot, some browsing, facebooking, whatsapp.
wifi on all the time and push enabled for activesyncemail, facebook+googleplus+twitter notifications, whatsapp messages and gmail.
I have disabled 3G and set my operator manually and most important of all I have unchecked the Allow wireless network-option in Location and security.
Did attach two screenshots showing the battery usage. I had to connect the USB-cable to take those (with ddms) so it did charge for a minute or so (same thing abit earlier so it shows a small charge period for 1-2 min)
A bit funny also that it shows battery gain in two places (which wasn't when I had the device USB-plugged) and also it looks like something has been keeping the phone awake while the screen hasn't been on.
But as you say it's not very often down to 10mAh as you get on the HD2. (3rd screenshot)

WOW i really envy you now , i should find whats making mine drop that fast in idle while yours can last that long while using it. i will check the settings you specified and report back the results
I attached a screenshot of the HD2 idle usage
Wifi
I've found that the culprit for mine is the Wifi.
I went from ~8 hours to 32,5 hours(is just about to turn itself off) by turning wifi off and on only when I used it.
This is with me watching a 40 min mkv show, and playing myth defence for 30 minutes and a little talk and sms and searching the market.
Wifi location function has been off from the start.
It's a bit weird because on the x10 mini it turned off wifi when the screen timed out and it held for about the same time, so maybe it's a "feature" they forgot to implement on this phone.
On normal usage mine lasts max of 2 days and thats pushing it. Normal use means I do browsing on it via wifi for maybe 10 minutes at a time per hour I guess. Will sync to wifi every 15 mins for 1 minute then off (via Green Power app). To help the thing, I am downclocked to 122Mhz on idle, max to 800+ on load via SetCPU, always on minimum brightness. Playing with autostarts too to disable apps to run and eat memory as well.
There is a higher capacity battery thread

But we're still waiting for somebody to go and test it.

At 10% the phone suddenly dropped to 1% and it did shutdown.
Something is draining the battery during the sleep and i cant find it.

Yes, this thing happens to me, 30% them immediately 1% and stays on for maybe 2-3 mins then dies (when in heavy use). I will recalibrate the battery stats when the phone is fully cycle charged (drained to dead, and charge on AC overnight). Hopefully should fix the issue.

Check the battery usage what consumes it (Settings, About Phone, Battery use).

yeah. it died again at about 10%, I did plug the charger and switched on the phone and it went directly to 10% again. Unplugged it and it died after a few mins. Did pull out the battery and inserted it again and now it started to behave correctly starting from 1%.
Another thing I have noticed is that when it reaches 100% it starts to discharge until it goes down to 95% then it charges again (quite normal behavior) but the phone still shows 100%. So it could be down at 95% when you disconnect it but it starts to tick down from 100%. I did check the kernel source and it was a comment there that it should show 100% while still charging in that mode.
It's possible to see the real value when using adb logcat|grep charge and also betterbatterystats shows the real value instead of the 100%.
thanks for the tip will try that. i get that same thing too, dies at 30% but when charged, it goes up at 30% immediately hehe... well, i didn't went to extent remove the battery though. what i do know is to have "Battery Monitor" sound some notification at 3425mA. At that rating, that just means I have some time to look for the cable and charge it.
Side by side, the st15i screen is significantly brighter than the st18i screen at the same brightness level. Though the st18i has a higher resolution, its colors appear more washed out, in a way though that is easy on the eyes. The st15i seems to be brighter and perhaps that is hurting the battery life.
Upon further testing, it appears the auto brightness feature of the stock rom is doing this.
With both devices in a dark environment, the st18i appeared brighter, with the same brightness settings.
Unfortunately, there doesnt seem to be a way to turn off auto brightness on the stock rom.
My mini pro's battery last much longer then it did on my old phone galaxy s2 so I have not a problem with battery

I'm currently on almost 2 days since charge and on 8%. And just when I started writing this it did just go down to 1% and a warning that battery is almost dead.
So it become 2% "better" ;-)
But I'm still happy with almost 2d with mixed usage and standby (wifi,push etc all the time).
Hi guys,
Is anyone having battery drain issues with their new sgs3's?
With my one it wouldn't last 12 hours without dying. Also if its at 100% it'll drop to 70% overnight while i sleep (6-7 hours) and thats with power saver on, sync off and running juicedefender.
Today I factory reset the phone and only installed flash, whatsapp and dolphin browser. Have wifi on, sync, data, gps and bluetooth off. Havent got pictures of battery stats yet since I only reset it half an hour ago.
So is anyone else experiencing battery drain? if so have you fixed it? and how?
Are there any apps I should be aware of that drain the battery?
I would remove juice defender.
Uninstall lightflow app if you are using it.
Use betterbstterystats to identify any wakelocks. The xda thread of the same name will be able to help with solutions.
Other than that follow general tips on increasing battery life that are found all over xda.
This device is easily capable of much better battery life than you are getting.
Good luck.

No issues at all so far, in my case. In fact this is the first Android phone I've owned that has no battery-related issues
Based on my previous experience what you can try doing is (a) install CPU Spy to see if your phone is entering 'deep sleep' appropriately (b) install BetterBatteryStats to identify offending applications.
Even the 'Battery' section in settings is useful -- just check if any apps are keeping the phone awake for longer than you've actually used them ('Stay Awake' number).
ok well ive installed bad ass battery monitor since its free. Also since I did factory restore i charged it to full and in 1 hour 44 mins it used 7% on idle. Going to charge it to full again and use it normally to see how it is.
Only apps ive installed is XDA, badd ass battery, dolphin browser and whatsapp.
maybe you have samsung widgets etc set to refresh every hour or shorter. Or could be Whatapp

Just a guess bit that might indicate that your unit has been shipped with a dodgy battery. I would get it tested and replaced.

Not too happy with my battery either. Fully charged over night and its down to 89% 1hr 30 later. Is that normal? However, you did mention lightflow earlier though which I have installed - Is that a massive battery drain? My battery stats seem to show display as being the big culprit but I have brightness set to it lowest setting.
Also, can't seem to find battery monitor pro on play?

I'm on Omega V4.0 and with wifi always on, fully charged 3 hours back and when i woke up it's 95% remaining. So about 1.66% loss per hour in sleep mode. With regular usage and installing and testing different roms and backing up etc them i easily get about 8~10 hours. Phone's made in Korea and battery mfg date is 2012.5.6.
Plus tons of widgets on home screens.
Been using s3 abt 2 weeks solid fone but i got one issue battery life on it sucks! funny thing when im using it for the web, video,etc the battery holds up pretty well but its the standby time thts killing it. I charge my fone full everynite wake up next morning and the battery's down to 56% jus on standby!! with nfc off s-voice off just wifi on. Am i only one experiencing this or is this normal?
you have something else going on i lose 2% overnight...try airplane mode see what happens
I think your charger may be broken lol. You charge it every night yet your phone is at 53% when you wake up? Anyway, assuming you sleep 8 hours and that your phone was at 100% that is less than 50% on 8 hours. You probably get 17 hours standby time, not the best but not the worst. Try airplane mode

Coming home with 80% left....
what says your battery settings? what stands by "battery in standby"? How much takes "android system", how many apps are listed in total? Do you have battery save mode on?=> Try to turn it off. Do you have auto brightness? Turn it off, set the display to 40-50% and make a widget on home with settings to 100% so you can read under heavy sun. You are outside the day?=> turn the wifi off....

no-one can give you a legit answer as you haven't bothered to tell us anything about what rom/kernel you are using, what you have installed, whether you have any syncs switched on..
why leave wifi on overnight? thats gives apps the chance to update in the background
have you looked at bbs stats?

You sleep with your wifi on? what do you expect to happen? Also try rebooting before you go to bed.

I think you have a defective battery. Mine just drains 2-3% in a 8-10 hour overnight standby.
I hate when people assume something sucks when it's their own doing that's causing the problem.

I still suspect this may be router related though. When I had my crappy Netgear, I would get strange periods of battery drain on my SGS2 when WIFI was left on. That just about all disappeared once I upgraded to an Asus RT-N16 running Tomato, and now, I don't get any drain on my SGS3 as well when I leave WIFI (set to "Always On" under Advanced WIFI Settings) idling.

I too think it's router related. It can possibly be due to Wifi dual banding in some routers that support it. Faster internet with less battery life.
Have battery drain in all roms minicm7 :/ even when i make a full wipe :/ gues is ultra brightness but if i unselect it d automatic brightness doesnt worck n if i put at the top the brightness without ultra it gets to darck ,srry bad eng. The pic say 9 hr.but i used ust 1 hour

Hi,
as you say it is with all ROMs and even after full wipe my only guess is that your battery is weak.
I would perhaps just try a new battery, they're quite cheap at ebay.
I have CM7 (nightly build) on my mini pro and no problems with battery drain. But I'm no heavy user, just a few sms or short calls per day, no games, no online apps. Most of the time my phone sleeps in standby with screen off. My battery shows 70-80% at the end of the day. I think that's quite ok for a little phone with a small battery. I heard the facebook app sucks battery like hell. But I don't use it, so I can't prove.
My settings are:
Clockspeed: 768 max / 122 min
Undervolt: on
Governor: smartass v2
Ultrabrightness: on
Wfi: off (only "on" when I really need it)
Bluetooth: off (I don't use it)
GPS: off (only "on" if really needed)
GSM/UMTS Data: off (only "on" when I really need it)
Maybe I could help.
Personally, I do a "wipe battery stats" from CWM now and then (let's say... every 2 weeks) and I have more than 48 hours (up to 72) usage with normal conditions.
Definitely works. Give it a try...

Go back to stock kernel for a couple of weeks, that might solve your battery drain.

u have to use InteractiveX as governor and 600MHz as max cpu frequency.. turn off ultra brightness and under voltage options and set brightness to %25-35 and try to off the screen when not in use then u will see ur battery drains over 40-50 hours...
There is no battery drain, your phone sleep when screen is off. Nothing is draining there. I have a x10mini, constant watsapp, won't last me a day. No games no browsing.

Me too have the same problem...
I had been fighting my battery for months, as it was getting worse and worse. It got to the point where using data would use 1-2% per minute, and at some point my phone would last 4 hours with minimal to no use.
Things that helped:
1- Finding what apps could be draining battery made the phone last up to 20h with little use. (In my case, Go Locker).
2- When I started using wifi only (like an ipod touch, let's say) without SIM, battery went up to ~24h with medium wifi use.
3- Flashed nAa's latest kernel and installed MiniCM7-2.2.1, and the first charge lasted ~40h. Then I found out I hadn't even enabled airplane mode yet.
4- Charged to 100%, removed battery stats, airplane mode on and gave it a bigger wifi use. 46h and it's down to 13%. When not using it, drains nearly no battery. This night it stayed at 14% for 10 hours.
Overall I'm very pleased with where it is going. I know I'm a new member do this may not even me worth $0,02, but I do belive the wipe + new kernel and ROM made a world of diference.
in all custom roms, is the same
Hey guys so the title says It all really, over night I can lose up to 10% which isn't normal I know
If I charge my phone up and use it straight I'll get about 5.5 hours out of It ( screen on time ) but if I don't use it to intensively it'll be about 4.5 which doesn't make sense
Sometimes when I reboot the device it goes down by a few percent as well, anybody had this issue?

Are you using STAMINA mode?
That's strange. Do you have a lot of IM apps and widgets/apps that updates in the background? As you probably know by now, you shouldn't see more than 1-2% drop in battery in 7-8 hours if you don't touch it. I'm on GPe now that doesn't have the fancy battery saving features, and i'm getting very good battery life. It's currently at 70% after 10 hours on and 2 h 30 min screentime.
It's probably something that's going rouge in the background, but check your apps that updates automatically.
Same as me
I lose up to 15% overnight
I have Line / Weather widget / Twitter / Facebook / and more
I did not turn on Stamina mode

Nowp. Got Stamina mode on, with only 2 exceptions: email + weChat, and also see a 10% drop each night.
I assume the problem is that Wifi or Data connection do not get disabled in stamina mode. You expect them to be disabled, until a request comes from the programs for a "poll event", reactivated, task finished, and then disabled again. But from what i can tell, the connections stay live.
Have you try juice defender. I use it better then stamina. I only have home page and none live wall paper and I only get 1 to 1.1/2% loss all night from 100% to 99 or 98 in the morning

I have noticed this once or twice before, last culprit was google keyboard in about 8h overnight it was almost always awake (about 50%), almost 2h of cpu time, used near 400meg of data - this was in SlimRom
Last night I had 81% battery before I went to sleep at 10:00. I then put my Xperia Z Ultra in Stamina mode. At 6:05 (8 hours 5 minutes) after my battery dropped to 80%
Therefore I only lost 1% overnight which is excellent.
Damn. Thought i was getting decent battery life (currently at 1d 6h on, 5h 25m screentime), but the way you're going you might reach 7 hours screentime on one charge...
And the cp12 isn't currently available where I'm at. Bummer.

That's really good, I'm on 70% with stamina mode on and 1.5hour screen on time
I'm thinking maybe my battery needs calibrating using an app? It shouldn't drop that much and it shouldn't drop a few percent by turning it on and off

Those battery calibration apps are a complete farce IMHO, modern batteries don't have their own internal memory like the old ones did, the best calibration you can do is a full recycle.

Yep. Also had a out of sync battery. Fully loaded ( green light ), it still showed 97% on the meter. So i drained the battery down to 1%, charged up to 100%, and voila ... Battery indicated correctly 100%, and has been correct every time.

just a reminder that the LED turns green at ~90% not fully charged
If you are in an area with very poor cellular reception and your cellular radios are on this can happen. It would help if you would post some screenshots of your battery usage in different scenarios; otherwise we can't help you too much
You could have a transistor leaking current or a short somewhere inside the device. Try a factory reset if you've exhausted all other options and if it persists contact Sony.
