Hi,
I'm currently using JuicePlotter to see how my battery drains over time and this past night I think it drained more than it should (or maybe not).
For the ones who don't know, JuicePlotter runs in the background (of course) analyzing your battery, that too wastes battery juice of course. Thought, the app dev says on his website:
Perhaps the most important feature of JuicePlotter is that - unlike all similar apps and widgets - it's very battery friendly;

So I'm not sure if the problem lies on JuicePlotter or not, I'll have to test it one night without it...
This is how JuicePlotter displays it's graph:
The coloured bands along the graph show your screen brightness, radio usage, charging status and battery temperature. Just scroll around to find precise information and make sense of the different colours.

I went to bed at 4:10 with the battery at 97%. Around 13:00, it was at 89% and I didn't receive any calls/messages/mails/whatever during the night. The WiFi/3G was off all night along with the screen of course. The battery temperature remained the same too. I don't know if it makes a difference but I normally turn off Auto-Sync if the WiFi is off too.
Is it normal to lose 8% of battery juice in 9h in standby? I think it's a bit too much, but I don't know... Does the same happens to you too? What else cloud it be?
Interesting looking app. I've never noticed much of a lose overnight. Just installed the app, will fully charge and give you an update tomorrow.
Also how's the cell reception in your area? I've heard it can drain the battery a far bit if the reception is low.

I'll have to do more testing but I think it's the app's problem... Tonight, I went to bed with 83% and it was exactly the same when I woke up...
I fully charged mine last night and turned on JuicePlotter. Still showing 100% this morning. Both in the app and on the phones battery indicator (in the notification bar). Do you know of any other apps similar to this that could be run in tandem?
Weird, Battery Graph also does the same thing...
This needs more days of testing on my part...
My battery goes from 100% - 0% in about 16hrs... doesn't matter how much I use the phone or not.
I have BatteryGraph but the results don't really mean anything to me as it just shows battery life vs time on a scale.
I'll try JuicePlotter to see if I can pin down exactly what's causing my terrible battery life.
I have a feeling it's running at full speed even when in standby but I'm not sure how to check if this is the case. Any ideas?
EDIT: Looking at BatteryGraph I've lost 15% in around 1hr... nothing unusual going on with my phone that I know about... just standard stuff running in the background. Perhaps the battery itself is simply past it's best.

Wow that is terrible, try apps like Taskpanel and when you add programs to your auto kill list the program kills the programs as long as they are running in the background when the screen is off, however if you are on lets say your browser and you don't go to your homescreen the screen goes off into stand by it will not kill the app. Also try draining your battery to the point it shuts down by itself, plug it in let it charge for a bit, boot into recovery wipe battery stats start up the phone or leave it off (your choice) and let it charge fully. Are you using setcpu or OC Widget or anything? If you are using SetCPU make a profile for when screen is off and make it underclocked like 264 Mhz to 480Mhz, or with OC Widget tick the 'use different screen frequencies' (don't remember what it is called since I don't use it) and do the same; I like SetCPU better because when you turn the screen on it switches profile faster where as OC Widget takes its time however with SetCPU do not use the widget it will cause Sense to FC and I'm not sure about Vanilla.
Hope this makes sense since all my ideas are said at once.

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Here.
That's interesting...
Cause I've been playing with ROMs latetly, creating my own, testing hacks and stuff... And most of the time the phone is plugged and the battery is charged, during the flashing process it's using the battery and then it charges again. I also have to leave from time to time and when I get back I continue my stuff, meaning I'm charging the battery at high levels.
I'll have to try that calibrate method...
For now, for the past 2 nights, with JuicePlotter off, I've noticed the battery level did not change at all during the night. Tonight I'm going to try one more time with JuicePlotter on...

Wiped battery stats at 5% last night, let the phone die and then charged whislt off until green light came on. Been keeping an eye on it all day and there has been a noticable improvement.
The phone came off charge at around 2am (so around 12hrs ago) and it has only lost 20%, which is a lot better than I was getting before.
It was probably just due to me messing about with some many ROMs and update zips lately as I tend not to have too much crap running in the background (I use OSMonitor).
I will look into setCPU but I remember trying it before with VR12 and it ended up causing some weird problems meaning I needed to do a full wipe to get everything working again.
Thanks for the help
This night, with JuicePlotter on, I only lost 1%, seems reasonable now... I don't know why that one time I lost 8% during the night. Maybe an isolated case? Something was probably running when it shouldn't, I just don't know what.
I really like this phone but the battery drain is terrible. I have that verizon extended battery in it(2750mah) but even with that the phone will lose about 10% battery in about 1 1/2 hours during non-use and roughly double that if im browsing the web.
I have Battery Doctor and Juice Defender running at all times and disable anything i dont need to have running. Also, for some reason Battery Doctor does not display my current battery status accurately so i use a basic battery stat widget to know exactly how much battery is left.
Does anyone have any recommendations on what i should do? Apps i should use/not use? Oh and i do keep display brightness down and have done a full cycle charge.
Thanks!

I don't know if this would help/is recommended, but I decided to bump charge mine once. It seemed to help me out, but opinion seems to be split on whether it's good for the phone or not. I also use only friends and calender widgets, and about 4 toggles (airplane mode, gps, wifi, mobile). I generally turn off mobile network where wifi is available. I have been off the charger since 8 am and am at 83% with light use (a few texts, a little facebook, etc). I do use Watchdog lite (to watch for misbehaving apps) and autorun manager (to tweak what runs on startup). I should probably also mention that I have the stock battery.
Turn off 3g manual in settings.
Make the Radio do 3G Only.
Put the phone volume half way.
No vibrate when receiving a text and audio play after the text.
No vibrate feed back when touching the home,menu,back and search button Which can be found in settings>sounds>haptic feedback. Uncheck it
-Monky_1
I have a stock battery.
I use the battery monitor widget to keep an eye on battery use and rogue apps. If I go over 50mA at idle, there's something that's running when it shouldn't.
I also have wifi sleep mode after 15 minutes of idle. And I keep blutooth and gps off. Also LTE only since i have excellent coverage here.
And i use Tasker to turn on airplane mode overnight (turns off all radios) and also silence all alarms, lights, vibration...
I get through about a day and a half of normal use no problem. Once cm7 is out i imagine i will get 2 or more days no problem, as it tends to idle at less than 10mA which would be a dramatic overnight difference.
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.

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.

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.

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 all
I know battery life has been discussed quite a bit, but Ive found most, if not all, discussions are "runtime" battery life, not standby..
For me Standby is important as I dont use the TP that much, but when I do I dont want to see the battery a 25% or lower!..
Currently webos 3.0.4 seams to drain around 5-7%/day, whereas Android CM7Alpha3.5, and Xron b2.1 appear to be about 20%!!
I know this is still alpha, but this , and only this, issue is stopping me from switching completely to android...
Any comments??
ps Dont get me wrong I know this is alpha, and the CM & Xron guys have done WONDERFUL things, just thought Id ask..
Anyone tried the new Miui build?? is it based on CM7?
Will CM9 be better considering its Android 4.0 "built for tablets?"
thanks all!
i mean, basic phone stuff still applies here. turn off wifi, etc. certain apps will kill your battery more than others (ie scrabble), even when idle.
idk, i find that it's easier to just shut it down completely if you know you're not going to use it for 8hrs or longer. i leave my tablet on all day when i leave for work and come home to see it about 10% lower, but i don't pay much attention to it.
I been at work all day long 10:30am - 9:00pm... I didnt have time to use my TP at all during any of my breaks so it was in standby the entire time.
When i finally got home and turned on my TP it was at 92% out of the 99% it was at in the AM.
Running Xron 2.2, i cut it down to 130mb, not a single problem yet since I installed it.
Hi guys,
good comments!
@thekillingtree : Yeah powering down is one option, but the beauty of a tablet, you keep it on standby...
@jzen : mm thats not bad, however 11hrs=7%, therefore thats about 15% over 24hrs...
Yes I know "things will" drain the battery when in standby when running in the background, i suppose Im comparing it to things like an ipad (less than 1%/day drain in standby), webos which is ~5%/day in standby and even the NookColor (v1) can go for 2-3 weeks in standby..
anyway, its still alpha for me Im hoping standby time will improve when it goes beta etc..
for now I'll simply keep it "topped" up!
Angelo
i'm genuinely curious how long the standby life will be. i fully charged my tp this afternoon and i'll see later how low it is.
i never really cared since i charge it every day or two.
Firstly you have to remember that the battery status monitor in android is all over the place and can never be accurately relied upon.
Flatten the battery (yes, I know it's bad practice!), then fully charge, wipe battery stats and leave alone until battery is flat again.
Then you get definative battery life, for your device/battery combo.
I know that when im done using the touchpad for a while.... i turn off my wifi.
the battery barely drops when wifi is turned off.
Idea: i wonder if installing juice defender will solve this issue.
--> Juice defender turns off radios and preserves battery life on my android
phone it might do the same on the touchpad. Just a thought i havent
tried it yet
good idea!
Actually yeah, juice defender worked a treat on my htc legend.. might help with the cm7 rom too
Sounds to me like it is not going into a deep sleep. I charged my tp fully last night, went to bed and woke up with 65%. I know this was an issue for cm7 and miui on my Droid x.

For this to be a meaningful comparison, you need to be running the same apps on webOS as you are on Android, and understand how the apps work on each OS (e.g., background processes, network usage, etc.).
The Touchpad has a 6000 mAh battery. According to Battery Monitor Widget (in Android), my TP discharges at about 40 mA while idling with the screen turned off. This is with wifi enabled and whatever background processes are running for the 150 or so user apps that are installed. If I were to just leave the tablet alone, it will drain the battery of 40 mAh in one hour. In 24 hours, it will have drained 960 mAh. 960 mAh out of 6000 mAh is 16%, so that's seems about right.
It's been a while since I booted up webOS, but I recall that the Govnah app will record battery drain as well, so you can see if the current is lower or higher with webOS.
So after having my phone for nearly a year (Razr Maxx) I'm starting to have extremely poor battery life. For example, this morning I left my house at 7:00 at 100%. Spent maybe 20 minutes looking at stuff on my phone, browsing a couple of webpages. Then spent about 20 minutes reading a book and listening to music. Now at 9:00am I'm at 70%.
I suspect that there is something that isn't working right on my phone... that I have some program (possibly malware) that is chewing up data or processor time or something. I'm looking for some kind of a utility that will monitor what's going on and is able to report what programs are accessing data and processor power. Anyone have a good suggestion?
If yor phone is rooted, try Greenify app.
Lower the brightness, turn off haptic, gps. Also install auto task killer.
That should make battery consuption a bit better.

First confirm if you have a damaged battery :
remove battery from phone and place on a flat table , if you give it a torque and it rotates means the battery is bulged
bulged battery must be replaced
if your battery is in proper
condition , to reduce battery consumption ,
freeze apps you barely use
remove unwanted apps , system or user
remove live wallpapers if any
decrease widget update frequency
install Ram manager app to see what is eating your ram.
