[Q] F+ battery drain?

I have F+ setup with push GMail. -It displays a facebook notification depended to received email from facebook-. But since 2 or 3 days ago, it somehow works in background even if screen is off and drains battery. And GMail sync is everytime active (there is sync icon ALWAYS on notification bar) when F+ installed on my phone, so I had to remove app. But it was cool to receive notifications live. Anyone else experiencing this, or have any ideas? except "clear cache" or "reinstall" bla bla..

Solved my Gingerbread Exchange battery drain issue (workaround)

Since Froyo, my Galaxy S suffers from battery drain if an exchange emailaccount is setup (irrespective of the update interval set). The only ROM & kernel which didn't do this was XWJPA with the Speedmod kernels.
Battery drain was easy to spot: SystemPanel would show that the CPU load while the phone was asleep was a steady 10-20%. Once the exchange account was removed, behaviour was back to normal immediately (idle CPU floating between 1% and 3%).
Since i like JVH very much, i have come up with a workaround in Gingerbread JVH: in Settings, Accounts and Synchronization, i untick 'Auto-sync' . This stops the idle CPU load.
Next, i have set up a task with Tasker, the task enables auto-sync every 4 hours, waits 5 minutes, and disables auto-sync again. This way, stuff is still synced every now and then without the battery drain.
Hope this helps someone.

Pls post your task settings for us to import. Thks

This does not solve the "suspend" bug.
Just tried it but after playing some game for testing this solution the suspend bug came back.

well you could try removing software update app.

Already deleted the software update app. Doesn't seem to help.
Any other (new) sugestions?

I have also seen this with my phone - but more importantly I have seen it on the server side as we have a number of Android phones, and we end up with a lot of processes running on the server.
I discovered by looking in the server logs that the email application is polling the Calendar on a constant basis. It is not just pinging the folder as it should do - it is also doing a sync every 5 minutes or so as far as I can tell.
My workaround is to uncheck the option for Calendar sync.
Other items Email, Contacts and Tasks all sync just fine as they are supposed to do.
Then every once in a while I check the Calendar sync option - perform a Sync Now to bring the calendar up to date - then uncheck the option again.
I do hope thy sort out this issue soon - as otherwise they have done a great job with enhancing the email application as far as ActiveSync integration goes.

Exactly the same issue I am having.. Calandar is syncing like mad.... Im using Enhanced Email for my exchange email and thats bulling 46% of my battery.
Have removed the calandar sync and will update on results once i have a few hrs usage

Update: stopping exchange calendar sync has fixed my battery drain issues on jvh.
Sammy may have made changes to the sync app and stopped it from behaving properly. Guess its manual calendar sync until they fix

update II:
Enhanced Email battery drain has gone from 40% to 4% since disabling calandar sync i now have more than 5hrs battery life

i m ready to disable all the calendar to get just few hours of battery

Please note that this needs the program Tasker, available in the Market.
1. create a new Profile with the context Time, name the profile as you wish
2. set the From: field to 00:00, tick Repeat an set that to every x hours (i use 4 houres)
3. tap Done
4. Add a New Task, name the task as you wish
5. add an action, from the category Net, choose action Auto-sync, Set to On, tick Done
6. add an action, from the category Tasker, choose action Wait, Set to 5 minutes, tick Done
7. add an action, from the category Net, choose action Auto-sync, Set to Off, tick Done
8. Tick Done
9. Tick Apply
This way, its still possible to sync (even Agenda) without battery drain

Thanks! This is consistent with something i have seen multiple times: if i opened up Settings, Accounts and Synchronization on the phone, and tapped the Exchange account, the grey spinning circle would always show next to the calendar entry, indicating it was in a sync loop or something.
I guess, this could very well be related to Android being sensitive to recurring appointments (and exceptions in recurring patterns) and appointments with large notes attached to them.
Could you point me to the logs on the Exchange server which lead you to this discovery. I'd like to dive in deeper.

My Quest of finding a Solution to Battery Drain and some funny stuffs

I have got my galaxy S2 for a week now. I absolutely love the phone. Just that the battery problem is killing me. I only manage to get half day of usage for the phone. Then I started reading infinite number of threads on xda on battery issue. I basically tried every possible methods:
flashing so many roms (on decided to stay on KF2 right now),
deleting all widgets(could be),
root the phone and install titanium backup to delete a lot of software which ppl
classified as the source of the drain(could be),
disable fast dormancy(dun see the difference),
disable push email and sync(could be),
using advance task killer to kill app every hr (dun work),
juice defender(dun work)...
etc etc...
SOMEHOW, my battery drain issue STOPPED yesterday!!! I still dunno what exactly is causing it to stop draining. But I DID find out a pattern, when we go to the battery plot section, if the phone shows a solid "Awake" bar, then the battery drains very fast.
So I started trying very possible way to stop the phone being "awake", the above methods I marked as cound be are the ones that I think can actually help. Using advance task killer does make a "segmented awake bar" for a few minutes, but it becomes a solid bar soon after, so no use (i found "clean memory" function comes with the phone better than ATK). Deleting widgets wont stop the phone being awake but it certainly makes my phone feeling lighter and faster. Then I rooted the phone, and start using titanium backup to delete ( i cant just freeze with free version) the possible softwares, e.g the hubs, wifi-sharing, softwaire updates. Then all in a sudden, the phone tries to sleep!!!
For me, I think social hub could be making the phone awake (at least it must be one of them), but I NEED if I need to use the email app that come with the phone for receiving emails from hotmail.
funny stuff starts....
So solve it, I imported my hotmail account to gmail using POP so that I can use gmail app to check hotmail. But then my hotmail and gmail start going crazy...!!
Reason: I did similar setting before in my hotmail account to receive gmails in to my hotmail account. What happens next is... Yes.. I basically created a "loop function" which makes the two accounts keep exchanging emails automatically to one another.. I received 1000+ emails in just a few minutes and it keeps going faster and faster.!!! > < Therefore I wont try this again!!!!
Can someone tell me a solution of getting hotmail emails in other ways besides those stupid apps (e.g android mail) in the android market which basically acts as a bookmark to get you to the hotmail page? MANY THANKS!

One of these might help:
POP your hotmail into a new yahoo mail account and install yahoo mail client.
Set up a new gmail account and POP hotmail into it, use gmail client to read main and this new account.
Figure out whats wrong with your phone that makes samsung stock mail waste juice, I use it for exchange mail and it's just a bit more hungry than what I would have wanted, I get through a heavy usage day just fine.

JuiceDefender surely helps. I'm getting 2 days with medium usage, KE7 stock firmware. Yes, as you said if you have background tasks, that will kill the battery, but just close them if you don't need them. Also disable auto-sync, and let only your email sync.

Thank you kreo, i will try yahoo mail account with ur method!

[Q] Can't get a decent battery life (lollipop) - Process "App Android Core"

Hi all, can you help me? I have just bought this device after a Note 3 and a Xperia Z2 and I am having problems with my battery life, possibly due to a process called "App Android Core".
The problem
Simply I can get a decent battery life... I can't get nothing more that 2-2,5 hours SOT. I know that is not normal. I think that the problem is a process that is called "App Android Core" . It is always in the first two places in battery consumption with as many time of process usage as Android System. In other Note 4 this process does not even appear in the statistics!
I have seen that this process is responsible for "logs provider, address book, user dictionary and contacts memory". I have thought that these may be related to Samsung syncs and I disabled it (though I couldn't delete Samsung account).
My data
I updated to official lollipop (ITV BOC5) the first day. Phone not rooted, I use Greenify.
2 gmail accounts, one hotmail with gmail app, one exchange with samsung email, one exchange with outlook; whatsapp, 2 twitter, instagram, facebook and skype.
I have Android wear with some apps for my Sony SW3.
What I have already done
I removed wifi network scan, I disabled the pen detection, put one of the exchange accounts in manual, brightness is on automatic 4.
Any suggestions?

I used to have issues wither User Daemon. Can you check your GPS devices battery usage? It's under "location" in the settings. I used to get 15 hours with light light light use. And now, since I disabled that widget and stopped that process (no root required) I get 2 days with my light usage or 4-6 hours of SoT in 1 day.

hi
first off ,
if phone is not rooted then it can be quite fustrating to pinpoint culprits !..........,as you don't have access to run the correct battery apps to id wakelocks etc ( eg BetterBatterystats ..)
( i have a N910F Snap ,rooted and currently on....... BOC5 (LOLLIPOP ) My battery standby and usage is acceptable (no problems ) No " unnecessary "wakelocks or battery drainers.
From what i noticed in your list of apps above and what i read on XDA forums , i have seen members complaining about Facebook etc ....been a battery drainer ? Is you location enabled ? Your syncing/push of emails ? i am also sure that apps like Skype etc will have effect on your battery .Having your data enabled , most of the time ...?
good luck

Hi, my biggest problem is related to that process. I have tried to format and reinstall and for half a day that process has disappeared. Now it is back again, it is rekated to the address book and maybe to some accounts synced with the address book. I have noticed it has come back after I have selected "personal view" into the address book. Now I have removed this view and syncing of linkedin and facebook

How to stop gmail from sleeping

Ive been using the zenfone 3 zoom for about a year now and I have yet still to figure out how to stop the gmail (or the gmail notifier app?) from sleeping. Thus when the phone is in sleep mode, I never get notifications for new email. Other notifications work (like texts, etc).
I think I have spent at least an hour in the stupid battery optimization screen, but still havent figured out how to make it so gmail notifications work in sleep.
Any ideas?
Thanks

In Settings, search for "Auto-start Manager" - make sure Gmail is on the "allowed" list.
