Hi,
For those of you that have Battery Monitor Widget installed, what kind of average usage are you seeing with the phone idle, screen off?
On my old Desire it'd sit at something around low double digits, 10mA or so idle with the screen off...
On my new shiny SGSII it's at about 180mA odd, which may explain why I struggle to get a days usage out of it. I've tried different ROMs (stock rooted, lite'ning, currently on villain 2.4.2) and different modems (currently KG6) and have used Ti to freeze all of the samsung bloatware without any improvement...
What kinds of values are others seeing?
Thanks
Jon
in idle , i get average of 50-60mA .. but after 3,4 hours of idle , i can get it as low as 9-10mA .. running on sensation rom 1.4 .. in normal use , it will hike from 100+ma to 400mA ..
it's actually a bit higher than my last desire HD. which in idle can get as low as 4-5 mA .. i guess that's all depend on the kernel ..
seeing at your idle usage about 180mA, that's definitely have something wrong somewhere. gotta find what apps draining the battery
Just did a test while I was down the gym - with mobile data off, but streaming music to a bluetooth headset, it was down to 60-80mA. Turn it back on and it's gone back up again...
Gtalk is frozen, Latitude isn't signed in... Nothing obvious shows up in Better Battyer Stats.. Other than removing apps one by one, any bright ideas as to how to work out which is the culprit?
I think i read that HTC phones actuality give true mah battery rates where on the S2 it is only get`s estimated.
I fully charged it last night, and left it alone overnight. Perfect signal (local picocell about 10 ft away), pretty much everything disabled, all user apps, samsung stuff frozen - only google apps unfrozen. Background data disabled, bluetooth, gps, wifi off.
After a few minutes, after a short while at 60mA odd it sat idling at about 9mA pretty much all night - used about 8% overnight. I re-enabled background sync, now sat on my desk at work with a reasonable 3G signal it's sat at about 60mA.
Time to start unfreezing apps and see what's draining it!

It's installed - I get a lot of events/0 and suspend listed in process, and not that many wakelocks listed...
I've just frozen the samsung email client (exchange) and the associated processes, and my usage has dropped from 60-100mA at idle to under 20 - looks like this may be the culprit!
Going to try unfreezing it and seeing if it goes back up again...
I gave up trying to freeze / unfreeze stuff - too much hassle.
So - did a factory reset this morning, so back to a totally fresh villain install. I even removed my 32G sd card in case that was causing issues..
Disabled automatic app re-installing, and have been slowly setting things back up while watching the juice usage.
Currently with touchwiz and all of the samsung crap frozen, no widgets running, my 2 gmail accounts and exchange activesync configured, and it's idling at about 50-60mA.
It's going to be a pretty drawn out process working out what's causing the drain

The S2 is essentially unusable right now, with the battery drain problem. I have tried everything described on these forums. reflashed the phone a dozen times, reset and tried every thing in the book. Only thing left is reflashing backwards to KE2.
Does that offer a less of a battery drain, than say the KE7? Mine is at such a bad spot right now, its not funny. Running stock KE7 with 3 apps installed, it's lost 30 percent in 3 hours. or there abouts?
Did u try to turn the wifi off ? I recommend you to try out the Juice Defender app which help improve the battery by controlling wiring and other connectivity. It will auto turn off wifi when screen off.

Yea i did. Bought the ultimate version of the app. Not much change.
How long were u playing with it in those 3 hours? What's your screen on time?

i Have KE7 installed. Its rooted and i am using Antek App Manager (free) to freeze some of the samsung crap plus using Android Assistant to clear cache and close programs etc. My battery is pretty good. last night, on a full charge, found out in the morning it used only around 7% of battery. During the day the battery usage had been good too. Wirless is on and background sync enabled, battery on 66%
I had KE7 installed from the off. Battery life has been improving for me (Only had the phone about 10 days)
I keep things down to a minimum (no Wifi, bluetooth, background sync).
I managed to get nearly 3 and a half days out of my last charge. This is with occasional texts, emails checks, phone calls and Google reader updates. I use launcher pro and have set the weather widget to update every 3 hours.
The battery on my Orance San Francisco hardly used to last 2 days with similar usage.
With the screen size & processor power, I for one am very happy with the battery life of my SG2.

None. I was snoozing. The handset had been taken off the charger, email account configured and i had taken a call. Fell asleep after that. Screen on time was 78 percent. (Only apps open were a gmail one, 3 browser windows and titanium)
Great life here
Just to add a counterpoint, I'm running stock unrooted KE2 and am having incredibly great battery life. No frozen apps or battery management apps, other than the stock settings that kick in after 50%.
I recently forgot to charge overnight, and still had >40% battery left after around 36 hours of moderate use.
This is with auto screen brightness, WiFi always on, no syncing except for gmail/contacts/calendar (With a fairly high degree of gmail traffic).
During that time I played Angry Birds, used GPS navigation, send numerous texts, emails, and phone calls. Recorded about 10 minutes of 720p video, took a bunch of photos, and browsed the web periodically.
I'd love the OP to send it back, and see if his new one had the same issue. Maybe it's his 3G, or maybe a just a bad unit? You paid alot of money, something this serious send it back.

There is a huge gap in the middle where you didn't turn on the screen, for like 16 or 18 hours (except once).... Be honest, while sleeping, do you hibernate? hehehe.

Lol. Actually I'm pretty sure the screen would have been on multiple times during that period, just not for extended periods of time. Perhaps they just didn't warrant an entire pixel?

juice defender doubled my batt life. i also froze some sammy apps with titanium.
have gone from 12 hours of batt life, (which i could live with, that pretty much what my n900 did) to nearly 2 days with moderate usage..

Wow... I would love to have that battery life...
Is it true that after some time of use of the phone the battery improves a bit? (I read it somewhere, but I don't remember where nor if they mention what was the reason for that)

Planning to do that today. Got just a couple of days left on return policy. If not.. well i am stuck. I love the phone. I want it to work... but 5-7 hours is just nonsense. I hope 2.34 ships soon and sorts out the mysterious drain.
Yep KE2 has much better battery life than KE7. For me anyway. I can get a full day's use out of one charge with moderate use and screen brightness set to 50%.
I have also frozen all the bloat. In idle with email set to push the phone uses about 2% an hour. Which is not bad in my books.

Thanks. That's all i wanted to know!
Are there any good ways to extend battery life besides the obvious stuff (no WiFi, GPS, screen brightness, etc.)? I just converted from my iPhone 4 to a Nexus S and battery life is pretty miserable - I can make it through a day but I have to plug in as soon as I get home. If I could stretch that 12 hours to 18 or so it'd be perfect. My iPhone could do 24-36 no problem, so I feel like 18 should be reasonable.
You can try different kernels for your firmware. The custom ones (good ones) normally consume less battery.
You can try to calibrate your battery, as well.
That is if you're rooted. If you're not there's not that much you can do. Install Current Widget from the market and let it be in standby for around 1 hour with WiFi and that stuff off, and check how many mA it's draining.
Other than that, turn auto sync off, and don't let everything send out push notifications (news readers, Facebook etc.) and if you're using a weather widget check that it's not updating every 30 mins or something.
BazookaAce, but having a smatphone like this without being rooted it's a waste of gadget...IMO.
Yeah, I'm rooted and running brainmaster's MIUI ROM. I do have syncing turned on for everything, I'll try messing with that since I certainly don't need FB or Twitter updates every 30 seconds.
just dont use any of battery saver tools. it doesnt work. wipe battery stat if ur phone rooted.
I have a similar problem. I am running an XT860 and am barely getting 12 hours and that's with an extended battery! I have read that keeping the software on your phone up to date usually improves the battery life.
What kind of droid do you have?
Root your phone, install cyanogen or miui.
Download setcpu app.
In setcpu, set it so your phone uses 500-600 mhz of processor speed when the screen is off.
That alone should help your battery life by at least 25%.
Not so sure setCPU is the end all solution here. I have this as well and I have mine actually down to 245mhz when in screen off mode, yet my battery life still is horrible. I have screen brightness pretty low and only gmail is setup to autosync, and checking the stats gmail does not use much of the battery.
I think it also has a lot to do with how good of a signal you get in your area. If your phone is constantly cycling through to get a signal that will eat up your battery as well and is pretty much out of your control.
Dropping the speed with the battery life sucks hd2 setcpu that does not taste at all
Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.

Hey,
I could not find a thread like this via the search bar, so I am opening one up. How much battery does your stock S3 consume by just lying there? I am losing about ten percent overnight, which seems a bit too much for me. Is that normal?
Thanks!
Wait till you get about 70 percent discharge overnight then you'll have something to worry about.

If you searched or read the multiple battery threads then you would have found that yes it is normal .
All depends upon what running .

At night I turn off wifi and data, my battery drops 3%, with data on and wifi off about 5% ( about 8 hours)
Based on reviews on the net it is possible to get it drop 6% in 16 hours with data and wifi on, not getting to this myself but happy enough.

It is very normal for Stock rom to consume that much battery.. However you can save more battery by going into Wifi > advanced > Keepy wifi on during sleep > Select Only when plugged in... Plus disabling wake up commands such as the ones for S Voice, or Google Now can increase battery life upto a great extent.
Also try turning off location services for apps that you don't use that often or the ones that don't really require location services that much.
I had 10 to 15% drop the night, after installing Chrome (because of google sync issue)
but after removed it.. im back to 6-7%
Anyway Dolphin is better
I can only say from memory ...

I can only say from memory - a very clean S3 should get at most 2-3% discharge overnight (even with WiFi, data, BT and GPS started). That might no longer be achievable once you have a number of programs that interact and keep the CPU from staying into deep sleep.
Currently I am seeing at most 1-2% with my configuration - but that involves closing the 4 above before going to bed.(and to get to that point I had to drop a number of programs that were bad in this regard).
Do your own tests with that - look around after BetterBatteryStats.apk or something like that!

I am currently running Omega v32.1 with the stock kernel.
I hardly use my phone during the day as I am at work for 12 hours, maybe send a few texts. 3g and sync are always on
I take it off charge at 5.30AM and when I get home at like 8PM it is down to less than 10%... and thats not even heavy use.
I have calibrated the battery using that batterycalibrate app for root users..
Hello everyone, I'm using Motorola Atrix with Epinter CM10 4.1 ROM for last 2 months, I was very happy with battery life. Phone wasn't getting hot and with normal usage, even with 3G on (in my country only options are 2G and 3G), I could get %40 of battery end of the day. But for no reason, phone has started to get hot (only 2G on) and drains battery really quickly for last 1 week. I can't even get %5 battery left from morning to evening now. I didn't change anything, only installed Adobe Flash 11.1, then I deleted it but nothing has changed. Phone gets into deep sleep no problem with that, no background apps. I did a virus scan both on phone and from computer, both came out clean. I reinstalled rom. Nothing. I'm gonna crash my phone against wall it's really annoying. I think I'm gonna do factory wipe and reinstall rom again.
Any ideas? Thanks in advance.
Do you leave wifi switched on at all times?
I use MIUI on my Atrix (partially based on epinter's work, I believe? Correct me if I'm wrong), but I have found that the phone suddenly starts staying awake for no apparent reason a while (often a couple of days) after I've left wifi switched on. This obviously causes bad battery drain. I can usually get the phone to sleep again by rebooting with wifi switched off (I think) and a battery pull is invariably required.
I now just switch on wifi when I have large files to download then turn it off straight afterwards.
Not sure if it is the same issue or not, but Better Battery Stats (which can be downloaded on xda) indicated the Rilj process was stopping the phone from sleeping when this problem occurred. It is worth trying this app to see if it gives any indication what is causing your battery drain.

No I switch between mobile data and wifi. Thank you for your suggestions and opinions but I really don't think my problem is about sleep. It started to get hot and drain when I actually use the phone. For example, I was checking Twitter for 10 min. with 3G and battery was dropping %1. Now it drops %5 with 2G on and gets really hot like 35-37 Celsius degree. I'm using Watchdog to oversee processes and nothing is working without my knowledge on background.
Hi,
I have the same problem on the nottachtrix roms since the last 2 weeks, I tried switching to epinter cm10 with no luck. Ordered a new battery to check if the battery is dead or if the atrix is faulty
if you find a fix, please post it here

install gsam battery monitor to see your phone's awake time. this drain happens to me also when i listen to music or take a photo. something with mediaserver keeps the phone awake and then only thing to do is kill mediaserver or a reboot.
Regardless of which other apps you are using to monitor app and process usage, I'd recommend trying Better Battery Stats as this is much more detailed and low-level than other apps I've encountered.
It's a free download for xda members:
http://forum.xda-developers.com/showthread.php?t=1179809
Little update.
I turned back to factory settings, then did a full wipe, cache wipe, dalvik wipe. I was so annoyed I even did system wipe manually from advanced options in recovery. I reinstalled Epinter CM10 rom, got my apps back thanks to Titanium Backup. Installed GSAM (thanks to saldirai), downloaded SetCpu and chose Nvidia Tegra 2 T20/AP20H, underclocked to 912 mhz. Couldn't done any undervolting sadly, says something about governor.
Now I'm checking battery stats and temperature by GSAM, so far no complaints and better from yesterday BUT I haven't use my phone heavily yet. Temperature changes between 26-31 Celsius degrees, battery drops %1-2 percent on use -also it needs calibration- with only wifi use which is always on. I'll update this post if anything changes.
Update: I think I've found the problem. When I choose The Weather Channel widget to "use my location" phone immediately starts to get warm. Weird point is, this wasn't an issue before. Apart from that I'm playing New Star Soccer and Carmageddon for 3-4 hours with wi-fi full time on and battery drops to %30. I'm really happy about that. Normal battery temperature is about 25-32 during the day and different from before it quickly gets cold after I stop playing games. Just like before.
