How i got rid of battery drain...

While I own an international unlocked version of the S2, i assume the Sprint version must be very similar. After countless hours of trying to figure it out, this is what i discovered and solved my battery draining issue (it's been two months with no problems at all) i get 4 to 5 hrs display time and it lasts me all day. I was on stock 2.3.3 and recently upgraded to 2.3.4. with same results. The following tips are things i did prior to rooting, and they solved my battery drain issue.
1. Anything that tracks location is a battery drainer and i discovered that i was using wireless networks for location (it's also not that accurate) and it was the biggest culprit, so i disabled it and now i use gps (more accurate) as needed and turn it off when done. If you use Google maps with google latitude enabled, sign out of latitude when done using it.
2. App killers use more battery than saving it by closing apps and processes that run in backgroung that will automatically open right back again. Stay away from them.
3. Some apps if left in memory will constantly cause cpu spikes (suspend and events/0), in my case it was Facebook and Xfinity apps. So i close all active apps in task manager. Don't really clear ram, just close active apps.
4. Use Watchdog from Market to track any apps that might be using a lot of cpu.
5.Enabling Back up my data also drained my battery, so i disable it.
Hopes this helps...

While I can't state for certain that it's causing any extra battery drain, Carrier IQ is hooking into the location service, and every time your location changes, grokking your latitude, longitude, accuracy, and a timestamp. This is new to the Epic Touch.

I constantly have alerts for suspend and event/0 in watchdog. In the stock task manager there really isnt much running to kill. It's driving me nuts. haha My battery life isnt horrible but I think it could be better..

Phone always awake :( What's wrong?

Wondering if i am suffering from the volume bug See...
Charging overnight: http://i44.tinypic.com/9930j7.jpg - Yet my phone has been "awake"?!
After 2 hours: http://i41.tinypic.com/2dim6me.jpg - Discharge almost 20% already and you see the awake time?
After 4 hours: http://i43.tinypic.com/302tok0.jpg - Faint! 50% was drained in 4 hours!
My homescreen: http://i44.tinypic.com/260e6tx.jpg - You will say is my Beautiful Widget, but I removed it and still phone awake!
How can I troubleshoot?

Exchange Services is really high. You probably have a corporate account that is having sync issues, and keeps waking the device.

Yeah I do have a corporate email account. But it's set to push notifications should I receive any e-mail.

Run BetterBatteryStats to see what keeps it awake. There's no reason why Exchange services should be that much of your battery.

Any settings I should take note of or set? What does blue/red bar means per app?

I think it is pretty obvious just by looking at your 2nd screenshot.

If u don't use Bluetooth (if ur rooted) , go to /system/bin and delete the file "bluetoothd" to fix wakelock
Edit: be sure to backup the file first

Yeah pretty sure it was the Corporate Email. I have since then remove the account and this is my result overnight from 100% downwards after 6 hours. VEry good results.
Thanks for your help.

My Exchange went nuts just like that, clearing the app cache didn't help but reflashing my rom over top again did, just cleared cache and flashed rom again and its back to normal, using 4% of battery or so on push...

Congrats on resolving your issue. Just to help others, is there any chance you know and could mention what o/s or version of exchange your work server is running? Exchange and/or the stock email app seems to be a problem for some but not for others. More info might just help someone isolate the root cause someday.

I did not flash. I just delete my account and readd it and it was fine after that.

New Outlook.com sync problems

I use outlook.com for my emails, phone book etc. Everything was fine with my contacts on my phone, I had all the small avatars for myself and all my contacts. I've got a big problem since MS updated me to their new style Outlook.com.
All my contacts Avatars have gone and I seem to have every contact in my phone from Facebook even though I have only chosen 'Outlook' in the settings. More annoyingly I have about 300 'Unnamed' contacts appear in my contacts and none of them have any info inside. I have deleted my account on the phone and resynced and it is still the same?
Has anyone come across this and any ideas how I can get my original properly synced settings back?

I have about 300 of these empty names now,

Did you already check in Settings > Apps > Outlook if all permissions are granted. If not, delete your Outlook account, set all permissions, re-add your account.

I'm using the outlook that is in the accounts settings and not the Outlook app itself. I've got my mail,calendar and phone numbers synchronised.
Maybe I'll install the App and give it a go that way and chose that setting in the phone app to see if that sorts it.

If you guys want to know some good email apps the type mail app works great so does blue mail I use both and they rock. They have like a 4.6 or 4.7 rating not many apps get praises like that. Just thought I would mention that as I think the outlook app has a lot to be desired.

Thanks for that but it's not the email I have problems with it's the Outlook account sync problems that give me hundreds of false empty entries in my people phone book when I sync to Outlook.com. They are obviously not in there so I don't know where they are coming from. It has only happened since MS updated me to their new Outlook.com style of page.

Oh I had that issue on Tuesday with the outlook servers using Thunderbird email software I had to force close a couple times now seems to be fine all day Wednesday yesterday and still going fine.

Samsung "notes" app - running too much in the background

Hi all
As you can see in the image, the Samsung Notes app is running wayyyy too much in the background, eating up my battery. This is even after I make sure the app is closed after using it!

I tried to set the app to go to sleep, but this was not possible as it is a Samsung dedicated app. I couldn't even optimise this app either. The only solution seems to be "force stop"ing this app, which I prefer not to do as I use the app once or twice a day to write notes.
Anyone have any thoughts on how to stop this app from running so much in the background?

Possibly notes is trying to continuously update to the Samsung Cloud?

Thanks for your response, but nope - I've disabled everything from being able to backup to Samsung cloud

Personally I don't understand why the applications stay active in memory after I stop using them, since I can't tell the difference even if my life depend on it if apps is cold started, or starts from memory, either way it starts almost instantly, so yes I would definitely force stop it myself, especially that I feel this "feature" of all apps staying in memory is more for advertising purposes than anything else, especially now. There is a switch to either put app to sleep or not allow background activity, one is under apps inside battery menu, another under battery usage menu. I'm trying to limit all apps from running in the background, except for map which needs to be constantly updated for traffic, but what a pain in the neck it is, there are over 400 apps on the damn phone.

Disable or uninstall this trashware.
Switch to an app that stores your notes in a standard format such as text files etc so you can always read them in the future.
Finding a good free office app is now almost impossible for Android. I use an old copy of Kingsoft WPS Office. Today's newer versions though are pure crap unless you pay, pay, pay.
Used Samsung Notes on my S4 but restoring them became a tedious nightmare when I migrated to the Note 10 platform because Samsang "upgraded" their app so it wasn't backwards compatible with their older version's note files.
Don't trust Samsung with any data you care about; they will make it obsolete by their time table not yours.
Thanks for nothing Samsung... feel the wuv for the rabid gerbils in the box.

Question Huge battery drain on standby

Hello there guys! I bought my Moto G30 two weeks ago and I'm experiecing a huge battery drain on standby, about 30-40% per day. I tried using plane mode when I go to sleep but it drains about 10-12% every night. Do you guys know how to fix this? It's really annoying. Thanks in advance

Clear system cache.
Disable all cloud crap including Goggle Backup Transport, Framework and Firebase.
Disable Google, manufacturer and carrier feedback.
Disabling Google play Services when not needed can be useful. Turn off location. Disable Gmaps if not needed.
Disable all power management then find any other apps that run in the background and deal with them on a case by case basis.
Optimizing a stock phone is generally a long drawn out process of trial and error
Karma Firewall can be used to block apps from using the internet and thus reduce battery drain.
Unfortunately in Q and above it's valuable logging feature is disabled. I'm on Pie and it works well.
Karma uses almost no battery, freeware, ad free, a perfect apk.

Thanks a lot, I did that but no luck. I have to try karma firewall yet but what I can tell you is that the only way to solve this issue (so far) is to disable Google Play Store completely, by doing that, the battery drain reduced drastically

I always keep Playwhore disabled.
It's a menace. It requires a reboot with both it and Google play Services enabled to connect to Playstore. Paid for apps from there like SD Maid will puke if it's not active and show only as the free version.
Playstore, the worst Google app there is.
Google play Services is enabled briefly a few times a day. I'm getting 7-11%@hr SOT with my Note 10+/Pie now.

Thanks a lot for your reply mate! Really helpful
