Battery Consumption Questions

Hi guys,
I have to say, compared to my HTC Hero and Modaco 3.2 rom, the battery life on the Desire seems pretty poor to say the least.
Do you have any tips? I know there are mixed views on task killers but whats the general consensus? Seems like every app that gets opened, seems to stay open forever or atleast open in the background on this thing. Is that good or bad?
Does the Gmail app which is push based I believe consume less battery than say the HTC Mail app used to sync about every half an hour?
Have you discovered any particular HTC apps that drain more battery than normal?
I've already disabled Facebook and Friendstream completely, use seperate apps for those.
It just feels like the battery eats away even when the phone is just sat there with the screen off, sure I have 3G on but Twicca is the only thing set to update every half an hour in the background and the Gmail app on push no doubt.
Any tips?

pretty sure if u slightly decrease the brightness of the screen and stop all data connections unless you want to run them will help the battery life

disable live wallpapers
disable auto updates
disable 3G (just for the sake of trying)
decrease the brightness or make it auto (dont put it to the max)
put plain black wallpaper as background (trust me it consumes 40% less than the colored wallpaper, again, do it just for the sake of trying)
try this for one day and see if you get anything different

I have the brightness set really low, don't use live wallpapers.
I would disable 3G but that kind of defeats the purpose of having twitter updates and stuff, one of the main features of the phone.
Just checked and Twicca is only set to update once an hour, this is really weird.

I saw somewhere that you can see what app is draining your battery life in the notification bar, just open the notifications bar and go to battery, and see if you find anything related there

I have the phone for 3 days and I'm still in the stage where I play with it all the time.
Day 1: fully charged at 1PM, used the phone pretty much non-stop till 10PM and finally plugged it in with 3% left;
Day 2: unplugged the phone at 8AM, had it in stand-by for couple hours, then used it non-stop for 2 hours, then 4 more hours of stand-by, then it 2 hours continous use. The rest was more or less stand-by. Plugged it in at 10PM with around 10% left.
Day3: used it quite a bit on and off during the day, still have 34% left.
I don't do any fancy power saving, though I don't like apps updating themselves, except for mail. However, I use WiFi when I can and I listen to podcasts whenever I walk/drive somewhere.
It's a bit too early to draw conclusions, but at this point I'd say that Desire's battery life is much better than G1's (I had 1600 mAh battery).
Of course it all depends on particular use case. Also, maybe the network is spotty in your area - that might drain a lot of battery.

Help me figure out how to improve the battery life

I am running AOKP M3 with franco kernel #15.2, turtle governor, 350/1000 w/ stock franco voltages. I also modded the auto brightness levels to ones of the MID mod. I use WiFi at home; I have set the power saver to switch to 2G after 1m of screen off time. However, I an unable to get more than 2-2.5h of screen on time no matter what I try. I plan to purchase the extended battery, but in the meanwhile what can I do to improve the battery life? I have the GSM phone.
Thanks in advance!

I've tried all sorts of stuff and 2 and a half hours is the most i've been able to get.
In order to do that I was using mostly wifi, auto brightness and I had undervolted as much as possible.
I've tried all different kernels and i've just accepted the fact that with this phone and the way I use it that's as good as it's going to get. To be honest i'm satisfied with that because in order for me to get 2+ hours of screen on time it has to be my day off, otherwise i'm too busy.
Also, i'm pulling 14-16 hours per charge with 2-2.5 hours of screen on time which in my opinion is great. I just want it to last all day and for me it does.

Try LeanKernel.
I get at least 4 hours battery life with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1200 Conservative
UV: Stock
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Brightness: About 40-50%
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
Even without the extended battery like you I would at least get 3.5 hours.

#1- people getting over 3 hours of screen time are on wifi the whole time, have 4g off, are minimalists with no syncing and no voice calls, or a combination of any of these.
#2 - based on your graph you have a lot of wake locks. Look at how often your phone is awake when your screen is off. That is KILLING your battery life. Disable or uninstall rogue apps, and turn off GPS and location services seems to help with this. Also reduce your amount of sync intervals if you can.
I have stock 4.0.2 unrooted GSM with extended battery.

Look at the betterbatterystats for wakelocks; looks like lookout kept half an hour, the rest are mostly sync.

Try to remove all widgets for a while. This can rule things out.

I'm running the exact same thing M3 with Franco 15.2 except I have the extended battery. This is with almost 0 idle time. Literally playing games, rrading forums, texting, etc.

Sorry posted wrong one. Here is my screen time.

Aww c'mon *cry*
I only have the calendar, clock and palmary weather widges (6 hour auto update). As far as I can tell Lookout and Sync are the *****es - literally. But that doesn't solve the idle drain, with the phone sleeping, it seems like 2-3% every hour or something like that.

That doesn't sound right. I have everything running as well. I don't use lookout any longer though. I'm sure if I just did the idle test I can get over a day of on battery time and still reach nearly 5 hours of on screen time. That's mostly Wifi which is suppose to drain more battery life, but I haven't seen the difference from being on 3G. This is a good set up.

I don't know if this is important but its a good note, I have not touched the performance settings or done any UV, not experienced enough, but I still produced those results.

I think you should try removing lookout. Take for example my awake times when screen is off. I sync Gmail, photos,remember the milk, and beautiful widgets.
Also major battery awake drain in beginning of my graph is due to streaming Google music when screen was off so perfectly normal.
Sent from my Galaxy Nexus using XDA App

Alright, I will remove Lookout. What alternative do you recommend, in case someone pick pockets my phone? Preferably free or cheap w/ Internet access. I'm thinking of Cerberus, as it'll be impossible for any wanna be thief to remove; I suppose the 3 EUR license is for device, right? Does it persist through ROM flashes (i.e. based on IMEI).
As for WiFi drain, on 3G it would be worse - it's longer range thus it needs more power and if the signal is bad (lucky I get top notch at home, not so at school), it's even worse.
When I get some more cash I'll order the extended battery and a dock off eBay, then I'll have a large main battery and the original one as a reserve.
EDIT: I've added the stats for this day. Better overall, the phone was used more intensively so getting a bit higher screen on time is good. I disabled Google Talk, I see it keeping the phone awake for a significant time, but I never use it. I also get rid of Palmary Weather and switched to the built in app, I'll see tomorrow how it goes.

The screenshots on the original post show sharp increase in battery drain when there is a) screen on and b) no mobile network signal.
In my opinion, these are two if the biggest culprits. The screen is obviously a power hog, especially with max brightness, and the lack of a network signal forces the phone to increase power to the radio in order to find a stable connection.

Well with the screen there's nothing you can do; A big screen will use a lot of power, a dense screen with use a lot of power, both is even worse. If this were an LCD instead of OLED the battery life with Holo would be horrible. Turning the brightness even lower than my tuned auto levels is not an option - the phone would be impossible to use due to the glossy nature of glass. As for the network, I can't do anything about that - the school building is built from reinforced concrete, that sucks up the signal pretty well and it's downtown, where the signal is already quite shoddy; at home I have a celullar tower 1km away so I get excellent reception, not so downtown.
But I'm not complaining about those. I mean the background activity, mostly the idle wake time. I'll see what I get tomorrow now that I killed Lookout and Talk, those seemed to be two major hogs.

Seems like you have a lot of awake time. Try disabling Maps, Google+ and remove all widgets and test it for a day. If it is better now, you have ruled out signal problems.

Is there any way to reduce the interval of Google sync events? (gtalk_async_conn) When I was at home on WiFi I got a sync maybe once every few hours (seen as wake). As soon as I left and turned WiFi off the sync was like every 10 minutes, which is weird, as in the AOKP ROM Control power save settings I set it to PREFER WiFi.
Why do I get a LOT more sync wakelocks on mobile data than on WiFi when the ROM is set to prefer WiFi syncs?

best pattery save I have found is turning off various radios
I use an app Profile that can turn on/off bluetooth and wifi based upon the time of day. So it turns on wifi at 7 PM M-F and turns it off at 6 AM when I leave for work. I get great battery life, and I think it is due to the radios I turn on and off.

LeanKernel stable... all the way!!... ive tried his OC 1.42/230 but you start feeling the drainage...

Believe it or not, activating wi-fi when I'm at home has actually increased my battery life substantially. No need to even turn it off; at the end of the day, it takes about 2% of your total battery life.
Care to post the "Power saving" app you are using, TC? The one that can activate 3G after the screen turns off? For so long I've been looking for such a powersaving app.

Battery life stats and questions

What's a good figure for battery life on the GS3? The best I've got is about 31 hours using on demand and bfq. Any one got better life using other settings? I heard someone getting about 43 hours life but that seemed to be a little unbelievable. Let me know what your getting
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

What you reported is definitely "the average". Most actually only get a day, if they're lucky of moderate use and have to plug in before sleep every evening and get going on charge in morning. So its more like 15 hours actually. And your 31 max is very common high end for people who've stretched it out.
I'm not sure if you're stock rom or not and if rooted either but that makes a big difference.
I'm rooted ( and would ALWAYS RECOMMEND ROOT FOR EVERYONE EVEN UF NOT FLASHING ANY ROMS AND STAYING ON STOCK. The ability to have full control is important.
Changing kernels and more importantly, undervolting, will give you that longer life you're looking for.
I'm currently on KyanROM with either Ktoonez or Faux kernel (heavily tweaking and testing both) and have this phone beautifully undervolted to exceptionally low and very stable mv numbers! Thus getting me that lovely 36-45hour average (you mentioned you saw posted elsewhere - yes it is possible and many are doing it). I basically only need to plug in every OTHER EVENING or night between 6pm and midnight depending on usage and I'm a moderate to heavy user (with a lovely 3-5 hours of screen time as well) AND I also have my phone overclocked to 1.8Ghz! Surprisingly, the oc doesn't make much battery life impact at all because the phone isn't constantly having to run at high levels, only in short spurts. Actually, due to rooting and kernel change I'm able to have my phone run as low as 192Mhz during much of its general activity and deep sleep ( which I get a ton of as my phone basically always goes into it when the screen goes off). This saves me A LOT of battery life.
I also use LTE, which is actually one of the biggest if not the largest battery hog, next to screen time of course. But with that being said I only use it when needed and have it turned off when not in use.
As for my peak I was able to squeeeeeze out 87 hours once, on my stock battery BUT that was with some abnormal(for me) measures that really help conservation. Ie, no LTE, under clocked to 1.2Ghz for good part of the three days, much less then normal screen time over the period of which I used it at lowest level with even further reduction via screen filter, I actually used airplane mode during my three overnight sleeps (which I seldom use but if you can hack it, do it! It can really save battery overnight. My current setup basically SIPS MY BATTERY AT 1% EVERY 3.5-4 HOURS OVERNIGHT WHEN IN AIRPLANE MODE), mobile data was off for most of time but did use my wifi at normal level (wifi uses less especially if good signal with few reconnects/scans), used my typical low UV numbers, kept my notification updates/syncs/wakelocks to a minimum and lastly kept my memory virtually clear if unnecessary background apps.
Doing ALL of this allowed me to get OVER THREE DAYS BATTERY LIFE. But keep in mind I seldom do many of these battery saving tips on a regular basis but some do and if you can, they WILL work to extend your life substantially!
To wrap up (this long winded post/reply) I'll give you my general UV mv range numbers and the typical everyday simple battery saving methods I use.
1.My voltage at lowest clock of 192mhz=800mv with gradual (smooth and almost linear curve) increase up to a mere 1200mv at a whopping 1.890Ghz clock.
I use NOOP scheduler with ONDEMAND governor most of the time, sometimes SmartassV2.
My screen off and deep sleep use this lowest 192 clock speed and with no wakeup lag.
2. I use my screen at 0% brightness most of the time (except when outside or in high lighting environment). I use the brighrness widget app to control this as it is easier and works better then stock settings. I actually even further reduce my brightness with Scree Filter App. That app is awesome and often use it solely for brightness control because it has full control and can dim it to basically full black if wanted. Which is MUXH lower then stock control. Fyi I use my phone a LOT more at night or in dark environment thus allowing me to dim screen HEAVILY yet it still is actually plenty bright with ample contrast in dark environments to do everything. This saves on my battery HUGE!
3. I use LTE when needed and GSM/HSPA+ when not. Seldom turn of mobile data altogether. I do turn off wifi when out and only using mobile data.
4. I use Screebl app to have screen turn off when not in use. Its great liitle app. Basically let's you turn down screen timeout to 15 seconds or less so screen is never unnecessarily on but it always stays on when in use due to the accelerometer and it knows when the screen is not flat on table! Its very annoying when browsing or doing stuff where screen isn't touched for long periods and the screen goes to sleep! But this stops that! So its always on when upright or in use and when phone down it turns off immediately.
5. Very important step and can take some time and research but making sure to keep partial wakelocks and apps keeping device awake to a bare minimum! DEEP SLEEP IS VERY IMPORTANT TO SAVE BATTERY! You basically want it to go into that every time your screen goes off and to stay in it uninterrupted for as long as possible. And many users phones are NOT making it into deep sleep due to partial wakelocks and they don't even know it or how to fix it. Not getting deep sleep can unnecessarily kill your battery!
I use a few tools here: Better Battery Stats/GSAM Battery Monitor/Battery Monitor Widget from within System Tuner Pro (which is my also my main and highly recommended tuner app for CPU oc/uc and UV,etc.).
These apps really help to determine what, if any, apps are causing partial wakelocks ( displaying in wake number amounts and overall wake time) allowing you to determine what to do to fix the problem and let the phone gets as much battery saving deep sleep as possible.
6.I'm not big on auto app killers and actually recommend against them as Android ICS does this already very effectively but do keep in mind that the more active background memory that is used, the more battery the battery is drained. So I personally kill unnecessary apps myself from the background whenever possible to save a little battery here and there. Using the apps listed above in #5 can really help to detect a nasty background app or service that is quite possibly unknowingly using a ton of CPU and/or memory, thus draining more battery and also often just slowing down your phone!
7. For those who can use it Airplane Mode is a big saver! Try overnights if wanted as long as missing notifications, emails, calls, updates, etc is alright for you. I seldom use it but it does help.
8. I almost never use my Bluetooth and GPS but when I do that is the ONLY time they are on. They get turned off immediately and really be careful with the GPS in particular because you might be surprised how many things on your phone will use it in the background, sucking your battery!
9. Be careful with sound and vibration levels. Haptic feedback too. I don't do much here but its anotherctip nonetheless.
10. Lastly is treating and charging your battery right! I found an amazing site linked down below in a couple of articles that really explains these batteries and how they work in a very in depth technical level this is still not too hard to follow. Aside from the two links I posted check out the others on the left menu as there is a ton of useful and educational info!
http://batteryuniversity.com/learn/article/how_to_increase_the_runtime_of_your_wireless_device
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
OK I've rambled on waaay too long here. Maybe I'll take this and post a battery savings tips thread with it lol. "10 points"!
Btw I've just received both my 3300mAh and 4400mAh capacity batteries. So I have much testing to do on those too and I plan on reporting back on them as well. Also with screenshots for data and proof...I can and will also post screenshots for all of the numbers and stats I've posted here today with my personal phone/battery accomplishments.
Hope this helps some of you out there because yes this phone can be known for terrible battery life but it CAN be tweaked to SUBSTANTIALLY IMPROVE that life to high standards and keep up with the best of them!

On Stock battery - Kyan Rom/Ktoonez kernel (at this moment)

Seems about right. My phone is completely stock and if I really wanted to I could even use it for 2 work days. I usually charge it over night though. I used it for 2 days though while at work, and with 3 hours of screen on time I was down to 7% battery. Around 40 hours on.

I was stocked rooted using Sammy kernel. On demand BFQ. I'll try on demand noop and see if that helps. My screen was about 35% brightness.

Can I hijack a little here? My battery seems to be atrocious. It was okay stock after my first 3 full charges I was getting about 12 hours and 2.5 screen time.
Here is what I've done with my phone since:
Flashed to debloated stock Rom
disabled remaining unneeded apps (example ATT wifi app)
disabled Wifi
disabled bluetooth
disabled GPS
disabled GPS autorun states
disabled 4g
disabled autobrightness, set to 15%
disabled location reporting
disabled Push email with Exchange
disabled Motion
disabled auto google backup
disabled keytones and vibrate on all button presses
disabled touch key lights
disabled Svoice
disabled streaming on googleplay, only plays from memory card
disabled Google Now
fixed the cell standby bug (even though it may not impact battery figured wth)
Uninstalled FB
Set all Autosync accounts and email to sync only once per day
No widgets (only Google play music, Smemo note, flashlight, and folders)
Running save power mode for low power screen, no haptic, and auto adjust screen to blacks
Running mostly black wallpaper, No live wallpaper.
Running medium intensity vibration
I ran battery stats and got a lot of wakelocks from googlemaps and exchange so I disabled the push email and set it to once a day. Google maps I disabled latitude, and shut down the autostarts with gemini.
It's getting to the point where the phone is basically a dumbphone just so the battery can make it while it sits next to me at work. Today I have 48% after 8 hours and 50 minute screen time and 20 minutes of google play (only playing from on SD card not streaming).
Any ideas? It seems like I'm getting less than average.

All I did was also flash debloated rooted stock. Set to top out at 1.5ghz power save on. On demand BFQ schedule. Screen brightness as low as I can to still read. And got 32ish hours. I'm going to try OnDemand and noop like the other guy said and UV a lot more and see how close to 40 hours I can get

Also, is that the built in power save that limits the processor or some other software?

I believe if you flash Sammy kernel it has bfq. I am on task's CM10 and kernel and battery life seems poor compared to CM9 or stock rooted

Strange Battery/CPU Usage

So my battery life has been average, nothing great but nothing terrible. Today I noticed the battery was draining quicker than usual and the phone was slightly laggier and warmer than usual. I looked at battery usage and "Android OS" was at 70%, when seemed abnormally high. I clicked on that and 'total CPU' was at 13 hours. Anyone have any suggestions? I uninstalled some recent apps and my brightness has been relatively low throughout the day..and I've restarted the phone a couple times. I also heard Android OS often can mean some Google services too.

That is insanaly high but i feel your utter pain bro..
My best advice is to try and restart the phone. Try and also remove the battery charge it fully and then just leave it for couple hours with the phone locked and display off.. Are you using NFC on location high, wifi and bluetooh all those battery eating goodies if so turn them off?
Try those suggestions and let me know how you get on. If you still having issues i tell you the next stage to the diagnosis (hopefully) which is what I i done lol..

Well, right now my phone is charging. Android OS is down to 55% which is still way too high. I've already restarted the phone a couple times and just uninstalled Chrome Beta since that was my last app I installed and I figured it might have been doing something. I use WiFi a decent amount but I almost always have NFC and Bluetooth off (and Auto-Sync when I'm not charging). I have location on "battery saving mode".

Hmm, Right that seems to abnormal the next stage is to hop on to the Play Store. Download and install an app called 'Greenify' this all go through your system to see what is running that takes a lot of apps and directs you to stooping/disabling them...
On a side note is your brightness level set too high or is it on auto brightness try set it on 40% if you can...
I can't really say much more at this stage? Try those up and report back

Well, it seems to have sort of fixed itself. I woke up this morning and "Android OS" usage was down to about 15% and the CPU Total and Keep Awake time reset also. On a side note, I got great battery life today by turning off Google Now, background data, auto-sync, location, and keeping brightness at about 35-50% (which I usually do anyway).

That's really good glad it's sorted it self out keep an eye out on it and keep me posted coz I had more to suggest but hey ho

I'm not sure on this one....you have to have an app somewhere that is killing your battery. My phone normally gets almost a day and a half easily. With Wifi and bluetooth constantly on, watching YouTube videos, and even screen sharing to my TV. Go through your Apps and find the culprit that is killing your battery.

go back to stock, watch drain for a couple hours install an app, rinse and repeat until you find the culprit.

Here, personalization service uses the GPS the most, but I don't know all the related Samsung apps that depends on it.

Same problem here, i dont use too much my phone, not gaming, not videos, just social Network and the telephone dont reach the 5 1/2 hrs screen time, most of the time is on standby, the WORST battery of all my phones in years.

Those with battery drain issue, are you guys using the Exynos version? Mine is Exynos and the battery drain is crazy since day one

Try this, it doubled battery life for me, especially since I spend the majority of my time connected to WiFi.

I'm using the Exynos version and not noticing abusive battery drain.

wifi will off mobile

technically, when you connect to WIFI, mobile data will not be used.
Except you turned on the use Mobile Data if Wifi connection or signal is slow/weak option

I had the same problem... Multiple factory resets and setups later, same problem. Was ready to return the phone because System was using WAY more battery than Display and I was averaging 2.5-3 hours SOT to 5% battery. Found someone suggest Bixby problems in another thread, disabled all Bixby related apps and now battery drain is gone, regularly getting 7-8 hours SOT with no problems.

One interesting thig I see in you first(high use) screen shot is the amount of battery used by adguard, where as in the subsequent image it doesn't even show up.

Because all traffic runs through adguard, battery stats are skewed when running it. It tells you this when you first activate it. I wasn't using it when trying to isolate my battery troubles, but I'm back to using it 24/7 and still get 7-8 hours SOT, so it wasn't the cause.

Bixby Voice Wake-Up was a huge drainer for me. Find it in apps, doesn't show up on battery stats page, but when you pull up app stats, it'll show how much battery it's used since last charge and for me it was crazy high.

This phone has had the best battery life by far of any I've owned. I'm on the US version unlocked straight from Samsung, using on T-Mobile network. Use it all day at work, been at work playing games and making fantasy football moves on my phone all morning for the past 6 hours and am still at 75% (and my battery widget that uses the system algorithm says I still have 14 hours remaining at my current usage level), and I use Always On Display on ALL THE TIME. Has to be related to an app or something. I will say though that I installed sideActions and disabled all the Bixby packages (along with several other Samsung-specific packages) since day 1 using CCSWE App Manager. I'm not a light user, either - I have Nova Launcher, several KWGT dynamic widgets, Tasker, AutoInput, etc...
Do ensure you have battery optimization turned on.

I had the same problem... Multiple factory resets and setups later, same problem. Was ready to return the phone because System was using WAY more battery than Display and I was averaging 2.5-3 hours SOT to 5% battery. Found someone suggest Bixby problems in another thread, disabled all Bixby related apps and now battery drain is gone, regularly getting 7-8 hours SOT with no problems.

Optimized settings, HD+, wifi OFF, AOD ON, GPS ON, notifications ON, Adaptive battery ON, unsued Apps Standby ON, deactivate auto. unused apps ON...
No problem here. Exynos Note10+.

This was directed towards the OP who IS having issues... some people are having issues, just because you aren't doesn't discount other people's problems.

Do you have any other apps you have disabled or frozen using CCSWE and can share the list please?
Disabling those Bixby apps helped a bit with my drain.
