Usually charge my Tilt over night. But just to check it I unplug it before going to bed.
Started at 100% when I went to bed, I got up 7 hours later and it was at 56%. That is far worse than I expected!
Is this normal? Or shouls I restore it back the the original ROM and exchange it while I still have time.
What did you have turned on? If you leave Bluetooth and WiFi on overnight it'll definitely kill your battery... you should disable them in the commanger when not in use to save battery life.
Also, if you have the mail client set to check for new mail often (every 5 minutes or so) it'll keep firing up a data connection which uses the battery.
Thats certainly not normal. check if you dont have Wifi or an 3G connection at the moment.
I did have bluetooth on. I am on a 3G network, but not connected to a data session.
I had this problem with one of the 'cooked' roms. For the 5 weeks I had my phone, I never had a problem with it draining overnight. I flashed one of the roms, and two nights in a row I woke up to a dead battery. I reflashed the ATT rom, and haven't had a problem since.
Overnight battery drain
I have a tilt, std AT&T rom, with some modifications and updates, found here. I have pop email service running every 15 minutes, and commontime Mnotes push email to my lotus notes files and email, bluetooth on at all times. My overnight battery drain, 8-9 hours will be from 100% down to 89-92%, so I would say there is something else wrong. If you have "battery status" (found in this wiki) on your today screen, it will show you battery drain. You should also have the tweak settings to turn off your 3G connection after 1 minute after completion of data transfer. If this does not do it, go back to the OEM rom and then add your updates.
It should not drain the battery like you are seeing, my reference as a guide and I push my phone pretty hard for data and email.
Good luck,

Totally agree.
there is also the posibility that you have a defective battery that's not holding charge. If you check with your phone supplier and tell them nicely that's the problem they will most likely give you a replacement (as they will send the old one back in the packaging as a return).
OK, I'll flash back to my original AT&T ROM and see what that does. I have another batter (1650 from ebay, a cheap one) but don't expect to have it for another 4 or 5 days.
it's a shame because I really like this Dutty's ATT Beta 2.
Anyone have a good full featured ROM their using that I can try if I find the AT&T original give me better battery life?
My overnight drain with bluetooth On and band set on EDGE is 4%. The only times I've found it low to dead overnite is when I've left WiFi On, not sure why as it should standby when off, but at least twice it's sapped the battery dead.

I wonder if when you get below a certain crital % battery level that cellphone or any Tx/Rx connection drops off? I have noticed once before (and never associated it with anything) that when I was near an audio device (my PC speakers are best for this) and my battery was low that it was 'polling' the cell network like crazy as if losing connection! This may also work for WiFi (which in sleep periodically checks if the network is still in range) and BT?
Something to investigate!
Overnight, around 7hrs, from a 100% battery with BT always on Wi-Fi off, 3G always connected and it's setup to check my email every 2hrs, I only loose 1 to 2% battery life and my alarm going off for about 5mins , this is with the Orange HTC Tytn 2 using their original ROM
Wel, I flashed the latest Dutty's ATT touch ROM. My battery did improve.
From 100% to 78% over night with bluetooth on. Not great but much better.
I'll see how it goes tonight.
My overnight drain is typically 5-7%.
This is with e-mail poll every 5 minutes, so data connection is on.
Bluetooth & WiFi off.
OK, checked it again this morning and this time at was at 98%!
I couldnet figure out why the day before it was at 78% and today at 97%. everything was the same (or so I thought).
I noticed later that the Radio pluging (to toggle BT, WiFi, and phone radios on/off) was not on my today screen. It was set to, but apparently didn't load. Maybe that is somehow the issue. I'll keep it off all day and see it I don't have more juice at the end of the day than usual. I'll turn it on again for tomorrow and see my my battery drains quickly again.
I think the battery capabilities may have a lot to do with this.
Anyone here use Li-Polimer for anything else? I do, minature 3D (no pun intended!) RC helicopters, and the individual packs NEVER produce the same charge/discharge cycle..
Not one is the same from purchase.
Some packs can devolve a low current without much adverse effect, others can charge with a greater sustain. If you present a charge cycle whilst discharge is taking place, it can effect performance.
Lots to look at here guys including device settings but when you put all these aspects together, as in this thread, there is something to work on...
I could've swore that when you turn your phone on stand-by (press the power button on the side to turn the screen off) that it also disables wifi until you wake the phone up.
I was having this same issue. Turned off Bluetooth and Wi-fi at night, hit the power button on the phone and now it only drains about 3% in the 6 hours I sleep.

It does unless the ROM you install changes the registry keys or you do yourself.
ah, okay.. well as long as the battery life lasts longer than the tytns then i'm happy
don't forget the default design of WM !!! ( X does not closes running programs ) ... get a task manager and make sure X DOES fully exit
I had to add that in to cover all the bases
I wasn't able to locate any threads on this using Google.
For some reason (I'm using the JF Rom...) although my 3G internet connection (and WiFi) works fine... My phone STOPS syncing w/ Google services. That includes all of them, Gmail, Calendar, Contacts. For example, today it's the 26th, there is no 'Sync' icon on the top panel, however, if I go to Data Synchronization, everything is Ticked (correctly), I get the 3 sync icons (not animated) and 23th of August for Gmail, and 22nd for Calendar and Contacts.
No matter how many times I try to disable and re-enabled Ayto-Sync, or try clicking them manually, it won't help. It usually works after almost a week, but I didn't have this issue a month ago... Tried w/ WiFi (in case it's my Mobile provider...) but no luck.
I've read somewhere that a guy left his phone on the charger overnight and that helped. Does this make sense? He said that his phone 'seemed' to remain on overnight (pre-charger) and was all hot n' drained the next day. Mine doesn't do this, still operational overnight without draining; although it won't sync.
well im not sure why auto-sync isnt working but i have a theory why that guys phonw wat hot and drained, usually when your downloading things through the g1's browser( like large files) the g1 gets hot, even though he left it on the charger the g1 was consuming more power than it was able to get, causing it to get hot and drain.... well at least thats what happens to mine when im downloading files from te browser or while tethering...
So I flashed the new Fresh ROM and it is taking FOREVER to charge. I finally got it up to 100% and less than 7 hours, it was completely dead.
Any ideas?
Me too! Killed my battery in 7 hours while charging overnight!
Have you looked at what's using the battery?
I know in some of the other 2.1 roms, facebook is constantly syncing which kills the battery.
You can use logcat in sdk to see what the phone is doing while it's idle.
Also, service can also change the drain on your battery. I know at work (inside a 3 story brick building) I get horrible service and my phone is dead by noon if it's not plugged in. At home, it can go all day and then some.
Same issues here. Takes forever to charge and dies quickly. I haven't flashed the new radio yet....could this be this issue?
I've been using it since he released it and battery life is more than excellent. I can go a whole day then some
Go under settings, about phone, battery. What is your uptime and awake time?
Then tap on battery use. What has the highest percentage of use time on your battery?
Also check out 'cell standby'. Tap it.. Time Without Signal should be very low, or missing.
up time 8:57
awake time : 2:42
highest use is close between cell stanby48% and phone idle 47%
time without signal : 0%
BTW my battery was at 38% with little use(a few text msgs and fb mobile a couple of times)
TWS is fine then. Do you have the sync icon constantly running?
And what is your PRL/PRI (sorry if you posted that already).
PRI - flipz_01
PRL - 60663
What about the sync icon?
sorry....no sync icon
Weird. Any mods/themes/etc?
What I would do at this point is wipe everything (including ext), and reflash, then see if you still have the problems. I haven't had those issues, so I can't give you anything else to look at.
Perhaps someone else can, but that's all I can think of.
You could try the new radio. Some have said they get much better battery life with it (which is likely caused by the radio not having to search for signal as often...but since your TWS is 0% I'd be surprised if that's it). Try that, then nuke and pave would be my suggestion.
Last night was the first night that I had my alarm set. Could this have anything to do with the drain?
I had a weird issue with the battery. I don't know what exactly caused it and I could not pinpoint it with "Battery Use" nor "Spare Parts." My phone was staying constantly awake though, no matter what.
I eventually just partitioned the SD card, with no ext partitions (no apps2sd), flashed fresh again, and now it's all working great. I am installing my apps very slowly and monitoring them to see which one may have been causing the problem. So far no problems though.

I was getting decent battery life when I flashed 2.0d originally so this might not help you but after I flashed the newest radio my battery life got way better. I can listen to slacker radio for 4 hours while studying and use the phone intermittently throughout the day and get about 12 hours out of the battery life.
anybody who has crappy battery life check if your phone is on GSM auto PRL?

I'm running Fresh Rom and my battery is great. I haven't charged my phone since 6:30am this morning(it's 8:30pm here now) and it's at 60%. I'm using the new radio too.
scratch what I said yesterday, lol... my phone randomly rebooted overnight and now I can't get it to stop being 100% awake...
EDIT: Tried rebooting, tried "power cycling" phone, did the CDMA (Auto PRL) fix just in case, didn't install any new apps, battery use shows TWS at 0%, Cell Standby Time on = My total uptime.
Spare Parts Battery History shows my phone as 100% running, no sleep time.
Spare parts partial wake usage just shows Android System..
Battery is draining like crazy..

That shouldnt be an issue any more. Flipz fixed it in 2.0d.
Change your screen brightness to auto. When I first flashed it was at the highest setting and killing my battery. A lot better now...
I fully charged my hd7 just before going to bed last night, i then did not touch anything on my phone just put it down and 8 hours later my alarm rings and i go to turn it off and noticed my battery was only half full. Does anyone know a way to check what is using the battery as i have not idea what it could be. Is it possible MS push updates at night? or is it more likely something wrong? I have been getting a day out of a charge with playing games and internet etc but this was doing nothing screen turned off no calls.
Have you changed any update settings? I've left my update frequencies as standard and seem to be doing fine.
How many power cycles has the battery had, as they seem to take a few charges to settle down.
this would of been number 4 so it could be that, the only thing new i added from the last charge that seemed fine was the htc hub so i have uninstalled that and hopefully i may have found the culprit.
Disable feedback as it can use the mobile data.
Disable update checking over mobile data.
Set email to download periodically rather than "as items arrive"
I have no idea if these will help and seriously doubt they will. I have just set these options myself after completely draining my battery in 14 hours of reasonably heavy usage. Fingers crossed.
I had a similar problem. I then realised that the speaker was hissing as though an application was still running. Don't know how to stop apps running so took battery out. Replaced it and seems to be ok now.
When you turn the phone off the speaker seems to be on for a little while afterwards. I keep checking to make sure it goes off now.
I've been looking everywhere and tried multiple methods to try and fix the following problem but without any success... please help!
I have a stock captivate which came with 2.1, upgraded to stock 2.2 last year, and just last week upgraded to stock 2.3.5. Never rooted or anything like that.
Up until last week, while I was still on 2.2, I had fantastic battery life, draining maybe 1% per hour when idle. After the update to 2.3.5 I'm now draining 10% per hour when idle. I've tried different watching apps to try and catch a culprit but I'm at a loss to point to anything. All the apps I'm using are unchanged from when I was on 2.2. My best guess is that it has something to do with wifi.
When I left the phone untouched on idle last night it showed 30% wifi and 25% cell standby for battery usage. My wifi sleep policy is set to never which is what I had on 2.2. I leave wifi on all the time, but I left it on all the time with 2.2 without any of these issues. I have 5 bars and am located near a cell tower so that isn't any different either.
I've tried factory reset as well as a couple cycles of draining the battery all the way down and filling it all the way up without any change. From a UI standpoint, I like the new Gingerbread update but 10% drain/hour when idle compared to a couple days when idle with Froyo makes the phone much less usable... Help!!
You could have an app that is running in the background taking up alot of ram and or CPU peformance. This can cause your battery to drain faster. Having a live wallpaper as well as apps that update in the background will also shorten your battery life.
however, there are many apps out there that monitor what the other apps on your phone are doing and will let you know if there is a rogue app taking up battery. Also, if you have the stock battery look into a new one. Its probably old by now and somewhat tired out.
I had the same battery drain issue upgrading to froyo. I ended up finding a custom GB rom and the battt drain slowed but is still faster than the stock rom. All apps have stayed the same since day 1. At this point I'm afraid to touch it again since it the wifes, and was a bit upset about the last time.

This was happening to me when I updated to GB but found it was one of the apps(No LED and Vlingo). I uninstalled and then reinstallled them and it stpped draining as fast in idle. I would also suggest getting the 1800mAh OEM battery for the Epic 4g Touch. It works great in our phones with 15 to 20% more life.
email app draining battery
I also updated few days ago to gingerbread official UCKK4 and after that my battery drains at around 5pm, whereas before it was around 11pm with froyo.
the battery log says email app is sucking it up. the email accounts are exatly the same 2 I had before: hotmail and company both configured as exchange.
Solutions?
thanks!

It seems like a lot of people are complaining of issues after the update. The most reliable solution would be backing everything up and performing a factory reset. Just be aware that when you do it, you will lose EVERYTHING on your phone that isn't already backed up somewhere else so make sure you grab your pictures, music, contacts that aren't already backed up in an email address, etc.

I did perform a factory reset after the update!
I have nothing on the phone, except few apps, which I quickly reinstalled.
The emails and contacts are on hotmail so, it wasn't a concern they get reloaded from the exchange contacts sync. music was on my external sd card.
the problem is that if I disable email, battery is fine...but, c'mon...then what's the point of a smartphone! and if I disable background check, it's also fine, but again, what's the point of a smartphone!
I am really concerned now... with this battery life is unusable.
We have two captivates in our house, mine and my wife's. For mine, I did a complete one-click flash back to 2.2 froyo and then immediately upgraded to KK4 through Kies. Overall, my battery got much better and gave me a good 4-8 hours more battery life than what I was getting. When I go to bed I'll still have 30% remaining.
Now the bad news: My wife's went the opposite. On Froyo she had better battery life than I did and she updated without flashing her phone. On GB her battery was dying in almost 4 hours, 6 hours at best. It was crazy. On Friday I took the phone, backed it up and performed a Factory Reset. For two days this gave her better battery life than 4 hours but still horrible. Maybe 8 hours total.
What I noticed:
Over the weekend I paid close attention to her phone. I noticed the 3G symbol would be displayed on the screen while she was also connected to wifi here at home. Then I noticed that her email app (not the gmail app) was the #1 use of battery, even over the display. Clearly something was wrong. Then I noticed if I opened the email app, it would result in a connection error. However, if I opened a browser or the marketplace everything worked normal.
My thought process is: the Email app is constantly trying to connect to its server and since it's unsuccessful it continues to retry non-stop draining the battery.
How I might have Fixed it:
I took her phone and put it into Airplane Mode.
Waited a couple minutes and turned on WiFi only. (Phone was still in airplane mode)
Waited a minute and then turned WiFi off.
Took phone off Airplane mode. When everything came on, the WiFi was still off since I manually turned it off while in Airplane mode.
Rebooted the phone, WiFi is still off.
Turned on WiFi after everything finished running from boot up.
Noticed that now the 3G symbol was gone when WiFi connected.
Today she unplugged her phone at 5am this morning. As of 4pm her battery has only dropped 25% (showing 75% remaining). I checked the battery usage and the Email app is back down around number 6 or 7 on the list. Not sure if that's what fixed it but the battery is a HECK of a lot better than it was before. If someone else sees these similar symptoms give it a shot and hopefully it will help.
I was having the same issue on my phone after upgrading to GB. The 3g would stay on (displayed) while I was connected to Wi-Fi. It seemed to be draining my battery. It is better after doing a cache wipe. Next, I'll be swapping modems and kernels until I find a better combo. Currently, KK4 with corn 7.06 (sio & conservative)

Interesting, I don't have wifi at home, but I also noticed at work (where I have wifi) that 3G and wifi icons were both on.
I am not sure I can reflash the phone, and I could try to reset the phone again.
I will try your "procedure" and see what happens.
1 more thing: as I said in my prev post, I use hotmail with both SSL checks, as exchange server.
additionally the other account, which now is disable (my work account), is a zimbra 7 server with again both ssl checks, and configured as exchange.
the same configuration was working on froyo.
my system is not rooted and nor modified. out of the box install.
Problem identified
I identified that the problem is the hotmail account.
I factory reset the phone again and cache wipe, then I did not install any app, apart from those which auto-update themselves.
I configured my zimbra 7 work email account (exchange activesync): waited few hours. Normal battery consumption.
Reset the phone again, then this time I setup only hotmail: battery drain.
solution:
now I am using stock email app for work account and downloaded hotmail app (seven+microsoft) which still allows me to sync contacts and calendar. It's suboptimal (i'd like to have all in 1 place), but battery consumption seems back to normal.
problem present again
Sorry, but after few days I realized the problem is still there...also using only zimbra (activesync exchange).
no solution yet. hotmail using its app seems fine, but no way to use stock email. after a while it starts again consuming > 25%
Correct me if I'm wrong...
So yeah correct me if I'm wrong, but I read somewhere that your Data connection and WIFI drain the battery quite a bit. I think I remember using something with a 2.2 ROM once, where if my screen was off, it basically shut off everything except the ability to receive calls and texts. I'm not really sure because that was months ago, but if this rings a bell to anyone, I wouldn't mind knowing too!!1!
Original poster here... After doing another factory reset, I only installed a few apps a day over the course of a week, waiting for the battery issue to reappear. Through this long process, I identified the Kayak and Facebook apps as the battery hogs. When I had everything else reinstalled except for these, I had the same or better battery power compared to Froyo. I contacted Kayak who said they were aware of the issue and just put out a fix. I think the problem was, an update for Kayak came out around the same time that I performed my upgrade (or the battery issue for Kayak was specific to Gingerbread) so it only appeared after my upgrade. Anyway, to be working better now.
Overall, I like the stock Gingerbread upgrade, especially the fact that Swype works a lot better after the upgrade.
Email battery drain
Hi all - I am beginning a search for some solutions. I just upgraded Cappy to stock GB yesterday. Did Factory Reset before and after which eliminated the Tethering Manager issue.
Battery life at home yesterday was AWESOME. I believe this is in part because the new GB defaults to a "never sleep" policy on Wifi. It literally went from 100% to 92% in 3/4 of a day, with Wifi on all the time.
Now its Monday and I'm in the office (NO WIFI HERE) and now all of a sudden "EMAIL" is the biggest user of battery. It's been draining almost 10% per HOUR this morning. I use Hotmail as my primary email and I have it set up through the ActiveSync server on the stock GB email app (not Hotmail-specific app).
What is going on? I have the Sync set to "Push" everything, which is the way it was on Froyo and it never ate battery like that. Is it something different in GB or do you think it is something to do with this "Wifi always on" policy that somehow the stock email app is always trying to connect to the MS Exchange Server through wifi but can't? (I'd think that when wifi is out of range that it would just default to 3G "pushing" which is what it did before, and again no bad battery drain before under Froyo).
Thoughts?

Cross fingers I might have solved this. Appears that having one's Hotmail and/or GMail CALENDARS synced up may cause the problem. It appeared that both of those Calendars were basically constantly re-syncing rather than waiting for a push like the email does.
I unchecked those sync boxes for both calendars and it now seems that battery drain is slower. I'll keep watching this afternoon.
Hopefully this post is helpful if others might be experiencing the same thing. I'm hoping that it is NOT the "never sleep" Wifi because from what I've read, that is actually a battery-saver when at home in constant range of Wifi. Perhaps that is why I didn't notice this Calendar-induced drain overnight because the juice was sipping at a much slower rate even if it was constantly syncing. Once I got out onto the 3G network this morning then the juice started getting gulped......

I had the same problem after the GB upgrade for my AT&T Samsung Galaxy Captivate phone. After I read this forum, I figure the Outlook email setup would be the problem. I did the following changes and corrected the problem completely:
1. go to "settings"
2. go to "account and sync"
3. click on the Outlook email account under the "manage accounts" section
4. click on "Account settings" under "General settings" section
5. click "sync schedule"
6. change "peak schedule" to "15 minutes"
7. change "off-peak schedule" to "15 minutes"
8. click "save"
9. Done.
"Push" setting in "sync schedule" selection is the culprit causes the battery drain problem.
Good luck
