I need help with my battery drainage, I cannot seem to track down what is the cause of my problems here. While at work I get a drain of anywere from 30-40 percent in about 5-6 hours! now that seems like ALOT.
I've tried stock, CM 6 R2, and Enom - I am on a custom kernel (2.6.35-925mV-CFS-SVS-720p-Monks-081010).. I am currently on that kernel and Enoms latest rom.
I've tried many things I've found on this forum. I installed "ShutUpBatterySaver", I removed my task manager, removed TiKL (heard it wasted battery while not in use), uninstalled ALOT of apps that I dont use/need just in case, Installed OSMonitor and watched to make sure nothing is using the CPU while its trying to sleep (I get less than 10 percent in use at any given time while the phone should be idle from android system mostly), I've stopped using live wallpapers and made sure my auto dim setting is on..
I'm not sure what else to do here Please Help!!
Thanks

Your system is using 10% cpu while the phone is IDLE??? Yeah, that's not right. Mine is in the noise (<1%) when idle.

me too the battery life on n1 sucks for me... i would unplug it then when i get to work on idle i turn it on it drops like 10 -15 percent in about an hour or so...??
Here is what I did.
1. Try to use black themes. I installed black desire bar and use black wallpaper.
2. Install SetCPU and set it to "on demand"
3. Change Wifi sleep policy to never.
4. Turn off autosync and use Shutupbatterysaver (This app automatically closes even after adding to task manager ignore list)
5. Remove widgets that auto refresh.
6. I'm using the same kernel as yours.
I also have **** battery life. Is it almost a must to calibrate the battery if you want to achieve good battery life?
Some people comment about how they have 36 hours of battery life OVERCLOCKED. If only my battery could come remotely close to that!
Unplugged my phone 1.25 hours ago and I'm already at 92%!
Edit: hmm, it tells me that my phone has been awake for 28 of the 75 minutes which is essentially impossible. Is there an issue where the phone takes too long to sleep?
I just recently got some very good usage out of my battery. Over night it only dropped something like 4%.
I'm not sure exactly what to attribute to as I've tried so many ROMS etc recently but the main things are probably
Installed SetCPU and set to 245min 500max
When in wifi location connect to it for data sync instead of 2g/3g as it uses less power when idle.

Something you're running is keeping it awake.. Most likely you have online/syncing/notifications on IM, Facebook, Twitter, something like that... Not the apps themselves, but them set to sync etc..
Spare Parts should be able to tell you what's keeping it awake.
What's UID 10018?

Some details I forgot origionally:
1. I have a black theme and my wallpaper is dark not black though
2. SetCPU is not installed but via spare parts I have my max at 107520 and govenor is on demand
3. My Wifi policy is never
4. i tried shutupbatterysaver and switched to juice defender but will probably switch back
5. I removed all widgets that auto refresh except the facebook widget (set to never refresh but it does anyway for some reason), and beutiful home widget set to update weather every 6 hours.

In the process of calibrating my battery by draining it COMPLETELY (as in I can't even access the bootloader) and then charging it fully. I'll let you know if that helps!
Seems as if it's helped quite a bit. I managed to boot up, deal with the phone for a few minutes and download a 65MB file over WiFi and when I unlocked I was still at 99%. Try re-calibrating.
Try removing handcent. I used on my g1 and out was a serious battery hog.

Hi,
im having battery drain problems the phone wont last more than 5-6 hours send 20-30 texts listen to some music, i have turned off backgroud data and live wallpapers, im using something called advanced task killer free to kill the apps that are running, but i close them the re open the task bar and stuff like music player has reopened
ive also seen a post about which batterys are better is there a better one i can buy? my batterys a G7
any ideas ?
cheers
Stop using the task kiler and you'll probably see better battery life. Task killers have been proven more harmful than helpful on the newer versions of android so using it is pointless. Also pay attention to what you have synced and how often. tons of web apps synching will drain the battery faster, as will having the gps and wifi turned on--if you're not using them, disable them.
thanks for the reply i will remove the task manager,
auto sync is turned off and i only use email by refreshing the inbox

In short: Have you recently updated via Kies to JPY version? If so, stop using your wifi. There is a bug with wifi with this newest firmware.
hi,
i update to 2.2.1 through kies
Do you use wifi?
If yes, switch to data, battery life will be better. You should be able to get around 48h of light active usage (i mean browsing and calling and what not) with 3g data on.
i dont really use the wifi, signals really good around me, i only got the phone friday, brought it of a friend,
charged the phone fully before i went out last night about 7pm by 1.30am the phone had cut off, that was only using the facebook andriod app and sending text messages.
Than there is something terribly wrong. Do a wipe and factory reset, if you didnt after getting a device from your friend.. It seems that some application misbehaves and drains battery.
You can check it by typing *#*#info#*#* in dialer
Several options there, if there is something strange you will see it. (suggest looking into Battery history, usage statistics)
i dont know how to type in dialer sorry sounds very stupid all i have are digits

Have you tried reconditioning your battery yet?

From the above post:
TechnicR said:
About my battery life:
Previously I was on Darky's v5, with that the phone lasted 2-3 days with normal usage.
After flashing to v7 (with 100% battery) I also got the fast drainage problem. Here is what I did:
1) Turn OFF phone
2) Charge till it says it is FULL
3) Start in RECOVERY
4) WIPE battery stats
5) RESTART android (yes, it might already be on 98% or so)
6) USE phone heavily. Don't worry if it drops too fast. Use it till the Android system turns OFF automatically (it happens when your battery is below 1% - for me the phone was on 1% for about 40 mins. This is where it heavily myscalculated
7) PLUG IN your charger, TURN ON android and wait till it is FULLY charged again. (It is better if you don't use the phone at this charging up)
Now, after you disconnect the charger, you should still have 100% for some time (I've been using the phone for 32 mins - writing this post - and it is still on a hundred percent) and with this, I got back the 2-3 days battery life with normal usage.
Also, you should set WiFi to: "Never when plugged in" and by default I disable Data Network. But my phone is using WiFi all the time so it doesn't really matter
So to summerize this method, the key is to show the phone the battery's minimal capacity too, by using it till it is on null. Because with charging to 100% than wiping or flashing only introduces the maximum capacity to the system and the minimum is only guessed. THIS gives the faulty reportes and makes us think the phone drains too fast.
Try this method, than feel free to share your results

This may not be the exact case you are having, but the idea is the same. Give it a shot.
nvm, 'info' stands for '4636'
You could also use titanium backup and freeze some apps from running

Thanks.
Same problem
hi
I have the same problem. I bought it 2-3 days ago. today i charged it full while fone was off, switched on at around 8AM my usage detail was
3g was on
gmail on sync
skype on sync
5-10 min of skype calling
5 min of normal calling
5-10 min of facebook browsing through android app
30 min of chatting on skype
at 2PM the fone was at 20% battery. My wifi and gps were off all day.
is there anything i can do to get atleast 15 hours of battery with normal use

If you are having issues with your battery, before you try killing tasks, changing setting and what not and especially if you are running custom ROMs, then you need to recondition your battery. The same goes for anyone who is having high drain issues.
If you follow the steps I posted from someone else's post and then find that your battery is not having issues, then start looking at your modem (if using a custom ROM or you've upgraded to new firmware).
ive done a factory restore, ive found what my usage says idle 4% the display 80%
contrast is switched right down
i know im not using any custom roms im using the firmware that you download through kies

How I solved my battery drain problem!
Have you tried turning off 3G?
I also had this issue battery drain was huge. It started appearing suddenly one day. Its a very slow process to figure out the culprit. I did a step by step analysis.
1. Found out that battery drain was happening only when 3G was on. Verified this by switching off data network (long press power button to deactivate).
2. Also verified abnormal data usage in my carrier page when I was not using my phone [like - 3G was on and I was watching a movie at a theater].
3. I also saw abnormal battery drain soon after I started Google Maps after a fresh reboot.
4. So I identified the culprit - Google Maps - but was not sure how to solve battery drain [Google Maps restarts, if you kill it].
5. I installed a variety of apps to identify the battery hog. Finally I went for Task Identifier.
6. Task Identifier finally showed me what programs started while my screen was off, etc. And I started noting them. Finally I figured out that Google Maps::BackgroundFriendService was running frequently.
7. A quick search on Google helped me understand that this is about Google Latitude. It searches for your friend's location every now and then - leading to battery drain!!!
8. I opened up Latitude and signed out from it [I guess the sign out option is in Menu -> Privacy].
9. Do not re-open Google Latitude after this - you will get signed in again leading to battery drain.
10. After 2-3 months of search and prodding, I finally figured out the cause of battery drain and fixed it - now I get 2 - 3 days of charge in my battery under normal usage!!
I'm happy now!!
Hi,
If you're using Froyo and can access file in your phone,
In task manager , on the tab "Summary", click on the "start monitoring" button. Let it monitor the phone over the night. The next morning, there should be 2 files created in your sdcard, one is CPUxxxxx and the other one is battxxxxxx.
The Batxxx tells you when the percentage of the battery at certain time of time. the CPUxxxx will tell you wht applications are running during that period.
When i used it first time, i notice that facebook and lattitude always running - when I stop these 2 tasks; i get a normal drain again.
while you guys are at it.
here's my "problem".
when I surf for an hour over 2g I losing about 10% batterylife and android reports that my display uses around 90% to 95% of the battery.
display is set to lowest brightness + screen filter.
is that normal? (im guessing it is not).
used dozens of different roms (stock, darky, jims, etc...), same behaviour everywhere.
i already did all the battery stat wiping and whatnot.
is it a faulty battery or display or something?
for the OP, maybe a combination of the above with this could help :

Now I tried the following two things with my phone:
For the first night, I left it at 2G only, with autosync disabled, and wifi,bluetooth,gps etc. off. All above apps were running, viber and whatsapp included, and obviously with no autosync, Gmail was not, so only the Email app that comes with android was running and checking email. In one night, it drained no more than 6%, over 8 hours.
The second night; again 2G only, and everything off, except for autosync, which I set to sync gmail only, and disabled the native Email app. In 6 hours overnight, battery drained 10%. This does not make sense for me, why would gmail drain so much battery?
Next, while I can live with those stand-by times, what is wierd is that while using the phone, the battery drains at unbelievable rates. I leave it mostly on 2G, barely using 3G every now and again. This morning, I left the house with 90% battery. charged it on my way to uni with the car, then when I got there played some games and a few songs for maybe 15 mins, then my friend came and we goofed around taking a video with the effects for a few minutes not more than 5. THen I went on for my lesson, took about 15 photos with no flash, with CamScanner and organized them into documents, then used regularly my phone to send texts, whatsapp and viber, then browsed the web for maybe 10 mins on 3G. By 12 o' clock, my phone was nearly dead (10%)! This does not seem normal to me, even though the standby times range from excellent, to acceptable it seems like the phone uses an enormous amount of battery when in use generally.The brightness varied from about 10% indoors, to 80% when outdoors. (most use was indoors). To make the time clear, I got to uni at 6.30 am, and while using the phone and games the phone was still connected to the car charger.
I have not done any modification to the phone. NO updates, no root (which I heard causes battery drain) no nothing.

hey, some tips if you want to extend your battery life, that worked for me, set display bright 50% and check auto bright mark, use some app like antutu cpu master (root required) to down your cpu clock to 1200 Mhz or 1000 (i used 1000Mhz), and also you should consider upgrade your firmware to v10h, you can notice the change in the battery duration, for me with all this tips, my battery drains about 30% from 5am to 3pm with a normal usage (gmail sync, whatsapp, email sync, facebook, twitter, some calls, sms), if you play casual games, battery duration goes down, but with cpu speed set to 1000mhz you can obtain a little more while gaming and avoid overheating

Thank you Ok, so is it safe to change to v10H? Will I need to factory reset everything? Because I would really like to avoid that? Plus to downclock would I need root? THen I'm going to definitely need to factory reset right?
Also which rom should I go for? I keep seeing the "Stock" roms and the deodexed zipaligned roms, which are better? If possible can you include for me a link to the actual rom you are using? thanks
BTW:: I don't have auto brightness setting!!
And is it wierd that gmail seems to be using way too much battery on standby?
This is actually quite 'normal' as most O4X users experience this notorious battery drain.
To extend your battery, you might want to do these:
1. Root your phone and uninstall any unnecessary bloatwares
2. Install battery saving app. A word of precaution though, for some it works wonder, and some experience disaster. I personally use Juice Defender and have seen some battery improvement.
3. Root your device and edit your com.telephone database. I've seen major battery improvement by doing this.
4. Get yourself some power banks. This thing comes handy when you're running out of juice.
You can browse this forum to do all the above.

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

I'm on stock, but without tweaks I can't even go the day on standby. [emoji31]
