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

how long does it take for your mini-pro to fully charge when is on?
2 hours and i have 13% from dead and i on to charge it.. i killed all apps...
This there something wrong?

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 every one battery life on android all are same like if browse for 5 minutes get reduce 1%....i tried so many andoid phones with larger battery the results is same..ln sony ray i think smal screen it may give good battery life...but me disapoint...i purchase recently have see after discharging 3 to 4 times..how it works..any ray user can tell their experiaence on ray battery life??

In stand by mode my battery drains for 1% per hour and when m using 3G and browsing then i drains about 13% per hour.....
I use task killer to kill background apps and keep brightness to balance condition
Also i keep my network to GSM only i.e to 2G when i don't want to surf net
It help me to get more battery life and i only need to charge once in a day
Hi all,
I was wondering what a "normal" battery usage is for the S2.
Mine (cm9) 10% per hour, pretty much idle.
Sent from my GT-I9100 using xda premium
There is no "normal" battery life. There are literally a million variables and thus no answer.
In terms of expectations - you would expect more life per charge from Stock GB, Custom GB, Stock ICS, Custom ICS in that order. Remember that ICS by its nature uses more resources generally and will not match GB for battery life.
Also, ignore wild claims about many hours with the screen on - it is a trick - they have the screen all black so no current draw...
Last time i was using Ressurection remix v1.3 AOKP i was getting 7 hours per 3% Phone was idle all the time Now i am using Thebyan 4.2 and battery drops 6% per 8 hours (idle all time )
And I am getting around 4:20 hours of battery life with normal usage ( screen on all the time plus Browsing via WIFI) Brightness - 10 percentage.
And while playing HD Games only 90 minutes !!
Well i prefer screen-on time over idle time

^^ this. Probably the best answer I've seen on here all week. No such animal. Just like there's no way you're going to get the same 'performance' with a given rom or kernel as someone else; which makes the "What's the best rom for <insert criteria here>' questions redundant and a waste of time as well.
This morning from 100 to 78 in 2 hours using edge and tapatalk xda forum. Screen at 50, GPS on, little Facebook. on formula one rom
Four days less if i switch the phone on .Even less if i use it .
jje
I get about 2 hours per 1% battery. That is with wifi on and screen off. If I have wifi turned off and airplane mode on I will get about 7 hours per 1% battery.
I always have my phone in airplane mode turned on, and wifi turned on, as I don't use the mobile network, and I am always in range of a wifi network
Cheers corey

CM9 and a lot of AOKP roms drain battery faster. Anyway my battery drain when idle is roughly 1% every 7 hours
well i get a decent life ,iam fully loaded an always install something,android is power hungry,so i don expect much of batt life...but i turn off wat iam not using like data,,,an in the night i listen to dubstep so i keep in flight mode an in morning switch back,so yes neva measured batt life,but happy....
The reason i start this post is to gather experiences and facts about Xperia P's battery life.
Sony was advertising that the compination of Novathor and Whitemagice results to almost 50% less need in power energy for the mobile and for that reason the battery of 1305 mAh is enought.
My opinion is that Sony has ultimately failed in this part.
My phone:
Rom : 6.0.B.3.162 (i dont have the signal drop problem)
network : WCDMA (3g)
Data: always on
Ayto sunch: Always Off
Live Wallpaper: No
Battery life: 10-13 hours
I usually use my cellphone for calls / texting / whatsapp/facebook. The thing that use my battery the most is always Display (always 60%-70% of battery) and the hour that the dispay is active, is 1h 30min to 2h 10mins. The average talking time per charge is 30m - 50 mins.
I usually charge my phone twice a day but if i use it for games or internet or photographs i have to charge it three times per day.
I m waiting for the ICS in order to see some battery life improvement . If i dont , then i ll sell it.
my battery drains 3% per 11 minutes on standby 3g / wifi on (with profile set at max 200mhz on screen off)
Can you please post your battery usage screenshot?
Sometimes even when the screen is off the phone stays awake due to some apps running in background. Generally battery monitor apps causes such problem. I have autosync on & network mode as WCDMA Preferred/GSM and use WiFi a lot though it is not always on.
For brightness as soon as I enter home I keep it at 0% & when I am to go out I change it to auto. 0% has good brightness. There is a widget available for this easy toggle. Also check your WiFI policy. Apps like VIber have tendency to keep WiFi always on even though you have kept the WiFI sleep policy.
I agree the battery is not that good but mine easily gets me through the day inspite of gaming, always Whatsapp on, Viber online & Facebook.
Note:- I have kept auto retrieval off for Facebook & default email client though notifications are on for Facebook.
Make ur phone root first than see wat ll happen after makd root battery life ll increase and u can control ur applications. If u need any help reply......

I have my phone for 3 days, an offer from the wife, no warranty though but the phone is like new. I'm considering selling it because I'm experiencing the exact same issues as you, charging the phone 2 or 3 times throughout the day is ridiculous. Had an iPhone 3GS and wanted to update my phone and migrate to droid. However I feel very frustrated about all the crap always running on the background, have 'easy task killer' and even killing apps then end up popping after awhile. I know I can solve this by rooting the phone but nevertheless I find myself always having to manually turn on/off wireless, 3G network, apps, etc... This is annoying and stupid, the whole purpose of a smartphone is to use its features, I find that although this phone has badass stuff (like HD camera) they are useless if one can't use them...
I'll try to fix this issue on the next couple of days if not I'll just sell this, go back to my old iPhone 3GS which with the same usage, wi-fi always on and 3G lasts a full 12hour day (at least) and save some more money to buy a 'decent' one like Samsung S III.
Thanks for your post, I thought my battery had issues and the more I read the more I understand SONY f-ed up!
For those who are using a moto X40 converted to Edge 40 Pro (or even a stock X40/Edge 40 Pro), how's the standby battery drain? Mine is around 1% per hour with dual 4G sims active, and with Peek Display enabled. However I think the standby drain is a bit too high for my liking and checking through the Android battery stats it seems like Mobile Network is taking a good chunk of the battery's power consumption.
I may be overthinking things though as I only had this phone for a couple of days :/
i don't care about battery drain, but i came from a iphone 13 pro max with 100 % of battery health, wich i still own, and this Moto like iphone gives me more than 2 days of battery, i'm not a heavy user, and with wifi at home endurance is better
