I have two spare batteries as battery life. Sometimes when I switch them it will rest the date/time. I've installed Clocksync from the market to auto sync with a time server on boot. It may still happen every now and then but I don't see it because Clocksync does it's thing before I notice.

Do you have to manually update the time and date if the battery runs out? My time and date has been reset.
I have had the same thing happen to me several times. If the battery completely runs out, you have to manually reset the time I think.
I've never let my battery run completely down, but there are several apps in the market that will keep your clock synced via NTP.
I have mine setup to sync whenever it sees wifi after a reboot and that seems to work well.
thanks - I wasn't sure if ntp was built into the kernel but my clock didn't update so I guess an app is the way to go.
Hi,
First post here, so I hope I'm posting at the right place.
Just bought an unlocked Samsung Omnia W (Focus Flash stateside) around four days ago. I didn't notice anything about the battery life the first two days since I was using it quite heavily and felt the rapid discharge was normal (the usual rigmarole- everything turned on).
Last two days, I've started using services more selectively, and still see my battery discharging at an alarming rate. I'm talking 5-8% in an hour with barely a minute or so of the screen being on for checking texts and sending a few.
I've disabled everything- location services, ALL live tiles, WiFi, Bluetooth, even went as far as to disable 3G and switched to 2G. I switched back to 3G because where I'm at I get a full 3G signal but a very light 2G signal. I've put off all background services (Gmapps was the only one, I uninstalled it). Turned off Xbox Live connection as well. Turned off facebook chat. Removed the People Tile. Three email accounts set to sync "as mail arrives".
I noticed the battery saver screen was showing me only 3 hours on 48% charge. I then completely discharged the battery through WPBench battery test (which showed 52 minutes starting at 25% battery life). Now, I've been charging it for an hour or so, and the battery saver screen shows 22% and estimates only 1 hour as the run time.
Is my battery defective? The WPBench time of 52 minutes for 25% seemed par for the Focus Flash (Engadget gave it a run time of 3 hours 30 on WP bench I think), but this fast discharge is really baffling and makes me kind of afraid to use the phone too much. I've heard the Flash has stellar battery life, so if anyone can throw some light on the matter, that would be great.
By the way, updated to 8107 two days ago through Zune. Normal usage consists of 30-40 texts a day, an hour of calls max and maybe 10-15 minutes of browsing. Battery saver screen usually shows only 9-10 hours on a full charge, though it does last a bit longer than that (14-16 hours). I'm sure such light usage doesn't warrant such a quick discharge.
I apologize if this makes for a really long read, first time here.
Thanks.
First, battery saver gives times based on previous data so it will get more accurate with time. Second, the battery will get better after about of week of use, it takes a little time to 'break in.' Third, if you are in an area that has poor reception your phone will try to find a signal a lot more and this can drain power quite a bit. Fourth, try returning everything to normal as far as background agents, email sync, and data settings ect. but turn 'battery saver' on after a full charge. If you still have bad battery life then perhaps somethng is wrong with your battery/phone.
EDIT: if you are using 'light' as your theme you will use a lot more power since amoled screens work best with black bacgrounds since the black areas are essentally 'off'
Been using a dark tile. Let's see how it handles with time.
A lot of my friends with Android phones simply keep data off since their batteries barely last if it's on, do I need to take any such harsh measures with WP? I hope not, I like my mail to arrive immediately (I have set sync on "as mail arrives").
Push email (the "as mail arrives" setting) is actually a very substantial power-drain. Setting it to even just every few minutes (5? 15? I forget what the next level down is) will help.
I may be wrong, but won't it cost less battery if the phone was getting push mail, say, three times a day for 3 separate mails as compared to checking every hour 24 times a day?
Why would you think that? The phone doesn't magically know when email is available for it, to only wake up the email sync process and data connection then and leave them off the rest of the time. It has to maintain a continuous (or nearly - often enough that you don't notice the gap) connection to the server. Even idle, any kind of live data connection uses more power than a process which stays suspended 99.9% of the time (meaning 86.4 seconds of activity per day, which is probably a pretty good estimate actually).

I thought push email and other kind of push notifications were sent from the server to the phone, and so the phone didn't have to be constantly checking for email updates...
The phone needs to be listening for those notifications. That requires running the radio (for data) at a higher-than-minimum level. Push notifications have a similar impact to push email, in terms of battery life. It's not hugely destructive - I have two email accounts that use push, and still tend to get through the day and then a bit just fine - but it does impact the battery life.
Hi.. i lost 20% over 5,5 hours in standby mode.. is that normal or something sneaky going on?
Do you have any apps syncing all the time? Some news apps sync every 15 minutes or so.
That seems like a high rate to me. Have you messed with any of the power options on it (made it not go into standby, etc...?)
I barely got that much drain watching a 3 hour movie.

I'd also check email syncing - if you a bunch of accounts that sync very often, it can affect the battery as well.
Also make sure your Bluetooth is turned off.
It happens to me sometimes and it seems like a reboot fixes it.
A reboot does sometimes work. Otherwise also make sure you close out office programs. I've noticed that sometimes runs down battery a little, though not that much. Are you hooked into WiFi, and is the connection where you are reliable?
i uninstalled few apps and rebooted and its okay now.. maybe it was because of Appygeek app.. try it out
Turn off all live tiles (maybe except mail, messaging and people which are useful) and don't allow any lock screen apps to run in the background which you can change via pc settings. This should significantly improve battery life.
Has anyone had the calendar miss notifications? I have my calendar set to remind me with a notification 10 minutes and 30 minutes before events, but the event I put in today had all three notifications happen after the set time. I received a text a couple minutes after the event, and that's when the calendar sent all three of the usual notifications.
Since my prior phone running Android 4.1 had better standby battery life, I have tried various options in Nougat to try saving battery, but I don't know what Google setting would cause calendar events to show up late. I'm just running an unrooted version of 7.1.1, and I have not gotten into anything other than what is available in settings. Any idea what Nougat setting could possibly cause calendar events to be missed? Other than this being some random error where the phone needs a restart, the only thing I can think of is if it's a problem with doze, which might mean changing the calendar to the don't optimize setting.
EDIT: It seems like taking the calendar out of battery optimization probably has probably caused calendar notifications to show up on time
Sometime between yesterday and today the battery went from about 40% to 0%, and the phone shut off. Google Play Services was the top battery usage, which showed 23% of the battery usage and 1204 mAh since the last full charge. I'm not sure how that makes since, considering the specifications list a 2770 mAh battery, so the stated usage would amount to around 43% of the entire battery. I suppose maybe over the holidays, I'll reset the phone and try some different settings.
Hi
I've got a brand new PH-1 and haven't yet had time to set it up properly, only started it up, let it update software and used for an hour or so before testing the idle battery drain.
I haven't installed any apps or changed any settings other than to disable the google app (to prevent it listening for or responding to "ok google"). I tried out the 360 camera, signed in to gmail and browsed a few websites, before charging back to full and restarting the phone before this test anyway.
But leaving it idle with the screen off and with phone network disabled (there's not even a SIM inserted), only wifi on with good signal, it lost 65% battery in under 22 hours. Screen on time was less than five minutes.
Is this a hardware issue I should RMA, or is it considered normal? If this is normal and there's no easy fix, I'll probably end up having to return the phone anyway for a refund, because if it can't even last a day and half in idle there's no way it would last a reasonable amount of time with normal usage.
Any ideas?
Thanks
Since there isn't a sim card installed, try going to airplane mode and then turning WIFI on.
I am getting about 1.2% drain with cell network and wifi enabled along with all my standard apps installed.
On a typical day with 1-2h SOT, I usually have 60-70% battery left at midnight. I'd try to reset the phone, and then testing again - occasionally a system update will end up doing something funny
I left it overnight with airplane mode on, so even wifi was off, and it's a little better but not by much. Screen on time was one minute.
With airplane mode on, screen off, no dodgy apps, the phone really shouldn't be doing anything to drain battery.
I'll try a full factory reset and see what happens.
Just to follow up, a full factory reset seems to have fixed the issue. Even after doing the same things I had done before (connected to wifi, updated, logged in to gmail, etc) the battery now drains at a much more sensible rate.
Very strange that a factory reset made a difference since it was new from the factory when I had the issue, but I guess something strange happened in the update like dsip suggested.
Thanks for the help!

That's ? percent normal behavior. Anytime you flash a ROM (new phone =new ROM) you need to wait a bare minimum of a charge cycle (more like three in my experience) before you get the slightest idea what your actual battery drain is going to look like. think of it like breaking in the engine on a new car.
