[AT&T Samsung Galaxy S II SGH-I777] WeldingRod:
sounds like as soon as you get the device you need to shut everything off an only enable mandatory items (and/or install different apps which don't glitch). Personally 75% of what I need my phone for is corporate exchange mail/calender/contacts/tasks. Sounds like I'll have to set my mine to 15min refresh and live with 3-4% battery loss per hour. This is still more than 24hrs. but combined with minor talk time not sure what that would result in, I plug mine in every night anyway.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
I have zero problem with corporate exchange sync. The only problem with exchange sync is Hotmail which I've posted many times that you need to turn off Calendar sync otherwise it will drarin your battery due to constant calendar sync.

Thankfully, MS released an official Hotmail app for Android. So I now changed my Hotmail sync to Hotmail app and use Email app for corporate exchange email. I have two Hotmail accounts, one corporate email account and one Gmail account. All setup to push and still have good battery life.

BTW, unless you set your mail checking to once or twice a day, you will end up with more battery usage using polling than pushing.

Of course, there are instances that the activesync server wasn't setup correctly that causes push email to use more battery. But that's really rare exceptions.

Motorola Droids uses entirely different 3rd party email apps. So are HTC phones.

EDIT: here is my phone after 2 hours on battery (96% left):

My corporate server is using Exchange 2007 ActiveSync protocol.
[AT&T Samsung Galaxy S II SGH-I777] jrl022:
Mother of all things holy I hate Internet Explorer. Had a response all typed out and something went quirky, I hit backspace to erase a character and everything's gone.

But yeah I realize both of the things you reference are true (push v polling and Droid Email app being different). This would seem to further isolate the variable which would be my specific email app on my specific phone. I'm not sure how it's a server issue if it wasn't an issue interacting with the email app on a different device. Maybe it interacts fine with one device/configuration but not another? I don't know.

Anyway, I've reset the device and it's idling with virtually no power drain over the hour and a half since the reset. It actually gained a percent the first hour (calibration?).

I'll let it chill a while longer before I re-setup the account, perhaps this afternoon.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
The exchange push email works by using a long HTTP/HTTPs session from phone to server. When something changes on your inbox, the server send a response back. But the phone also needs to send a heart beat signal once in a while to tell the server that this http session is still alive. This heart beat interval is somehow controlled by the server and I saw in some instances, a server can be misconfigured so that the phone is required to send heart beats too frequently which inevitably increase battery consumption.
[AT&T Samsung Galaxy S II SGH-I777] knimrod:
From a fresh charge, I've been losing about 7% per hour with Juice Defender Plus and light use.

Last night before charging, I turned off "Background Data" and so far today after 4 hours and light use, I'm only down to 92%. That's 2%/hr and quite an improvement!

What the heck? What are the downsides of leaving this turned off? I see that I can't access the market without re-enabling background data but what else? Can JD+ manage this automatically? I don't see it in the settings.

(phone is still not rooted)
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
For me, not having Background Data turned on makes this expensive phone a bit useless. I might as well just get a regular flip phone or Blackberry! Something else must be draining your battery. I have this option on and I am getting about 1% drain per hour at idle. I recently completely factory reset my phone and started to add in my programs one at a time. After each one I monitor the battery and cpu usage. So far I have found that TextFree app causes an additional 1% drain on my battery per hour.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
With background data turned off, only the app you're currently open and displayed on screen can use data.
[AT&T Samsung Galaxy S II SGH-I777] knimrod:
Understood... But what is the potential downside to that? "Data" is a broad term that seems to define a fairly narrow range of use in this case. I can still get text messages automatically and get my email manually. What other apps would be noticeably affected? Thanx.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
Basically all the sync services like email, contacts and calendar, weather etc. If you always manually retrieve them, there is no downside.
[AT&T Samsung Galaxy S II SGH-I777] knimrod:
Thanks.. That's what I thought. It kind of sucks but the increase in battery life is huge. Now, if I can just figure out how to make JD+ do it automatically on a schedule, I'd be pretty happy. :)
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
Here's another option...use Tasker to turn on and off Active-sync every X hours. That should help save battery.
[AT&T Samsung Galaxy S II SGH-I777] knimrod:
JD+ has an option to manage data connectivity on a schedule but this seems to either not work or have much effect on battery life. I've had Auto-Sync turned off and even that didn't have the same effect of turning of background data. Something is still actively syncing unless background data is turned off it seems.

I've also installed BetterBatteryStats to see if I could get a handle on what was waking the phone and using up all the power but either I can't figure out how this app works or the info I'm looking for is buried in some generic system service.
[AT&T Samsung Galaxy S II SGH-I777] dandrumheller:
If you use GoogleVoice for your sms, or if you use an IM or chat app instead of SMS, these services will not get notifications.
[AT&T Samsung Galaxy S II SGH-I777] knimrod:
For what it's worth, turning off background data has been a huge gain in battery life for me. After 11 hours of light to moderate use today, I'm only down to 75% battery.

I rooted my phone this evening and will try to sort out how and what bloatware to disable so I can get similar results with background data on. If I can do that, I'll be pretty happy.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
I don't think bloatware uses that much of battery if you don't launch them. The real culprit is probably anything you syncs, emails, calendar, facebook etc. Or some rouge app you installed.
[AT&T Samsung Galaxy S II SGH-I777] rbtconsultants:
Thanks for your wisdom. I'll believe my benchmarks. They're repeatable but maybe they don't apply to everyone. That's why I said they affected my battery rather than speaking authoritatively as if I knew they applied to everyone.

Bob
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
The problem is there's a lot of bloatware that auto-launches.

On a stock ROM:

Settings->Applications->Running Services

Prepare to be horrified at all the crap that's there. The SNS services are notorious battery hogs, there's also a hidden DRM service that doesn't show up on that screen (SisoDrmProvider) that keeps waking up and phoning home to check licenses for media, even if you don't have a single DRMed file installed.
[AT&T Samsung Galaxy S II SGH-I777] jrl022:
Yeah I'm definitely not doubting your results. It does seem like there's a lot of variation between the results we're all getting with the same phone and at least *similar* email settings.

I found out a couple more things in my case yesterday:

- My company is running Exchange Server 2003, latest SP. That's at least one discrepancy from Foxbat's configuration right there.

- Whether I'm set to "push" or once every "X" hours does not seem to make much of a difference in how often the email program is waking my phone. I even set my phone to Airplane Mode last night and there were several period where my phone was awake and drained more battery than it should have (I lost around 12% over 7-ish hours, which I would take if the phone wasn't in flight mode).

I've installed a trial version of Enhanced Email this morning and set it up to see if it experiences the same problem. Gonna let it charge for a bit then find out.

If I weren't pretty much the only person in my company with an Android phone I'd love to compare with others to see if they have similar issue, but there's only maybe two other guys with them. And they should probably be using Jitterbugs so I can't see them being a lot of help.
[AT&T Samsung Galaxy S II SGH-I777] foxbat121:
In theory, Exchange 2003 should get you better battery life because it strips out all the HTML junk in the email and send you just the plain text email only. But there could be other protocol improvements in newer Exchange servers. After all, Exchange 2003 SP2 (or 3) is the first ever ActiveSync push protocol implementation from Microsoft.

Also, how many emails you receive per hour may affect your battery life as well. I average only 2 or 3 per hour.
[AT&T Samsung Galaxy S II SGH-I777] XGhozt:
Are you sure? I've had multiple instances where my battery percentage would drain rather quickly and then get stuck at a percentage. For example.. 4 hours of use and my battery level is now at 30%, then I get an whole hour of usage before it hit's 25%. I even seen my battery level go UP 1 or two percentage when I turn my screen off. After using up the battery and restarting the device the reading is fine.

What else would cause this? :confused: I will admit, this is my first Samsung device, and all my previous devices where HTC. I'm not afraid of being wrong, but I would like to understand what the difference is.

Right i feel like a propper n00b i've done a search and couldn't find the answer i was looking for so i appologise if this is already out there.

Basically i got my HTC Titan today and i'm 90% setup just need to find out how i can change the menu option so my apps will be listed like my HD7 as they are in alphabetical groups can someone point me in the right direction. I've included a pic sorry for the quality was taken with a Xperia X10 Mini.
[Windows Phone 7 Q&A, Help & Troubleshooting] derausgewanderte:
you need the right amount of apps to get them alphabetically categorized. I think the number is something like 40 or around that. Looking at your image you are probably still very fresh with only a small amount of apps. Games won't be counted towards the apps I saw from other threads.

btw. Titan, great. I am envious ;)

Hi,

so I always have my bluetooth headphone on for listening to music. Sometime when I want to watch a youtube clip or any other video, I hear no audio in my bluetooth headphone. You can hear the sound via the speaker but no the bluetooth headset. I thought an software update probably would fix the issue, but now that I have mango update, even then it doesn't work. Is it my handset or is it this phone??

Thanks

[G2 and Desire Z Q&A, Help & Troubleshooting] G0belet:
Hello,

I've been trying to root a friend's Desire Z recently. It's a French (AZERTY) version. I first S-OFF'd the bootloader, using my XTC Clip. He now has real radio S-OFF without downgrading. However, we now have a bigger problem: the keyboard is now QWERTY.

I've been searching but I can't find anybody with that problem. My "trails" so far would be CID (changing it back to a French one), or a switch somewhere in misc.

What I tried so far:

Swap .kcm files

Try to edit CID (to no avail; I need to downgrade first or use ENG HBOOT)

Try to read misc (again, no dice, it might've been my friend typing the command wrong)

Try a new ROM; Cyanogenmod didn't fix the problem, which is not surprising considering the Sense original one did the same after S-OFF

Did anybody here had that problem, and if so, how did you solve it?

Thanks in advance!
[G2 and Desire Z Q&A, Help & Troubleshooting] G0belet:
Found out. I flashed a misc partition from another French Desire Z, and turns out using the French CID fixes everything. Hope it might help someone!

Or, you can use misc_version-0.2 to change your cid (or eng hboot and fastboot commands)

-Nipqer
[G2 and Desire Z Q&A, Help & Troubleshooting] G0belet:
I compared outputs of "fastboot oem boot" from both how it booted before, how it booted after flashing a new clean misc.img, and another Desire Z which didn't have this problem.

What the XTC Clip does is emulating a HTC Engineering SIM Card, which allows access to the Radio NVRAM. By doing so, it clears the S58 bit, which is the Radio S-OFF everyone is trying to achieve.

But it doesn't stop there, it also clears the SIM Lock, and sets the CID (Carrier ID) to the SuperCID (11111111), which allows flashing of any ROM you'd like. It clears the Backup CID too, and the ModelID (it became PC10*****, allowing to flash pretty much anything). It's a very thorough method to unlock.

However it came with its problems, namely the fact that it didn't know the keyboard was a French one anymore, since the Carrier ID didn't specify it anymore.

I tried several methods, but nothing worked, until I flashed a friend's misc partition I extracted from his phone, which worked normally.

I compared the two misc images, and saw two differences. The first bytes of the misc partition contains a backup CID (I don't know the specifics about it though). The unlocked one was set to FF FF FF FF FF FF FF FF (thus, empty), so it didn't override the SuperCID. The clean unrooted one was set to HTC__203 IIRC, which is the "HTC France" CID. There was also a bit somewhere in the clean one that was set to 01, while the unlocked one had 00. Maybe that was the switch too, I don't know, since I edited both and flashed it back to the unlocked one, which gave me back the French keyboard as it should've been.

There is a list of CIDs floating around, that should help people to set it back to what it should've been.

I didn't read the tutorial, but changing back the CID to the one you had before should get you back your keyboard.

What I had booting before fixing the keyboard (fastboot oem boot while in bootloader/fastboot mode):

(bootloader) setup_tag addr=0xA0000100 cmdline add=0x8D0878FC
(bootloader) TAG:Ramdisk OK
(bootloader) TAG:smi ok, size = 0
(bootloader) TAG:hwid 0x0
(bootloader) TAG:skuid 0x25209
(bootloader) TAG:hero panel = 0xF
(bootloader) TAG:engineerid = 0x4
(bootloader) MCP dual-die
(bootloader) MCP dual-die
(bootloader) TAG:mono-die = 0x0
(bootloader) Device CID is super CID
(bootloader) CID is super CID
(bootloader) Backup CID is empty
(bootloader) setting->cid::11111111
[...]

What I have now (from memory):

(bootloader) setup_tag addr=0xA0000100 cmdline add=0x8D0878FC
(bootloader) TAG:Ramdisk OK
(bootloader) TAG:smi ok, size = 0
(bootloader) TAG:hwid 0x0

(bootloader) TAG:mono-die = 0x0
(bootloader) Device CID is super CID
(bootloader) CID is super CID
(bootloader) Backup CID is HTC__203
(bootloader) setting->cid::HTC__203
[G2 and Desire Z Q&A, Help & Troubleshooting] xd.bx:
Thanks G0belet, this information is very interesting. However I don't really get why the misc partition and more precisely the CID has an influence on the layout of the keys. Does it change the behaviour of the radio which somehow would manage the keyboard and thus change the keycodes sent to the Linux kernel? Please enlighten me :)

BTW, I had the very same problem you describe on my ChaCha after S-OFF'ing it. I worked around it by manually swapping a couple keys in the .kl file, but this is a rather messy approach.
[G2 and Desire Z Q&A, Help & Troubleshooting] Nipqer:
Sense roms come with multiple CID files, which the phone uses depending on your backup cid.
