HELP: Froyo killed my parents & my battery life

I know there might be a dozen threads about this, but its all gobbledygook and nobody seems to have a straight answer.
I just want to ask: What can we possibly do about Froyo draining our battery? Task manager auto-killers aren't working right now it seems.

Turn off 4G
Turn off WiFi
Turn off GPS
Turn down brightness
Stop opening crap
Problem solved.

Task Managers??? Are you kidding me? My battery life has doubled since Froyo because I dont use task managers or auto killers. Use Fresh Rom, with set cpu with perflock off, change the screen off to 245/245. Most important part is condition your battery...Trust me, i thought it was stupid as well, but it works.

haha thats funny and true so i like it. i am running froyo official and have noticed an increase in battery. but hey when you get near your computer plug your phone in when you get in your car plug your phone in.

Froyo Killed Your Parents??
Sorry To Hear About Your Parents
R.I.P.

theres not much else u can do..just wait for a fix

I have ota and its the worst batterie ever with out doing nothing not even a phone call it died under an hour i only have gps enable had 3g off 4g to app all close no auto killer
Htc Evil Phone

I have the same problem. I read reports that Facebook 1.3 will not release the partial wake lock. I took FB 1.3 off and the problem persisted.
Here is how to check if you have a problem with your partial wake lock:
goto settings > about phone > battery and compare the uptime and awake time. If they are the same or very very close you have a wake lock problem. A wake lock allows an app to prevent your phone from going to sleep, even if the screen is off. If these times match then an app is creating a wake lock and not releasing it, and therefore your phone never sleeps.
As I said removing FB 1.3 did not solve the problem, but I was able to prove it is a wake lock as using Advanced Task Killer to kill 21 tasks allowed my phone to actually sleep, as indicated by a corresponding difference in the two times. So now that I know this is an app doing it, I will try to narrow it down and figure out which and report back.

OK I just found it. It appears the LED Light widget also causes a partial wake lock. To alleviate you don't need to uninstall it, just remove the widget.

Which led light? From market or the one with 2.2?

The new "flashlight" app is not a widget...It's actually called LED Light, by picolyl.

I don't have a problem, for me is little better!!!! just buy a new battery that solve your problem

Problem NOT solved. Or maybe 15 extra minutes.
Or don't use it at all, you'll save plenty of battery

Check to make sure that your Google Talk app is not automatically signing in. Go to apps - talk - settings. This is a typical battery drainer

totally forgot about google talk. have flashed a few ROMs back and forth, and now running a stock rooted ROM, I forgot to shut this one off...

use a custom rom, something without sense and try not to have a f***ton of widgets. im running cyanogen nightly and i get about 10 hours before i hit 20%-30% thats when i quit doing stuff and start trying to make the battery last. screen eats most of the battery so turn the brightness down.
my average 10 hours is 75-125 txts 30 + or - min of talk time and 3+ hours of internet (facebook)

oh, and about your parents... they are gone, there isnt an app or a rom that can fix that.

Indeed, the title of this thread is goofy. Froyo has literally killed my parents....... and has done a bad job for my battery life on my phone. Haha!
I guess an apostrophe would not have hurt after the word "parents" eh?

Doing a factory reset will fix your problem... I had the same problem when I updated.

I'm having similar issues with my OMJ 2.2 froyo rom. poor battery life, plus it seems laggy and unresponsive. i was much happier with OMJ's 2.1 rom

I have figured out the solution to the battery problem many of us have with Froyo

- Update to AOSP Email.
- If you are using Exchange, use Push only. Do not use the interval syncs.
- Uninstall / Disable Juice Defender
- Uninstall / Disable ATK
The whole problem is wake locks. The current Email client has an issue with wake locks if you use Exchange ActiveSync and do not have Push selected.
As well, if you have ATK installed, and it kills Email, then when it starts up again it will enter another wakelock.
Juice Defender causes the same problem by disabling the radio - basically, Juice defender makes the battery use worse, not better, because the re-sync of the email every 5 minutes makes it go into wakelock mode and never let go of the CPU.
After fussing with upteen dozen kernels and roms and modems, making these 3 changes has had a REMARKABLE decrease in battery use. I am burning my battery at less than 1/2 the rate I was previously.. I now burn less than 3%-4% / hour. Which means I will easily get through a full day with the phone.
EDIT: The other thing to make sure of is that you don't have the buggy version of Gallery3D that drains your battery due to holding onto the sensor. Your best bet is to just totally delete the APK from your ROM, and install the one from the market if it is an app you want.

Title is a bit misleading, please add problem with email battery drain, because a lot fo the froyo drain issues is for people not using the email and not even connected to data network mode.

You said update to AOSP mail ... anything wrong with the stock Email.apk?

Here's something i discovered, but wouldn't mind confirmation from others.
When waking your phone (with the charger not connected), is there a one second delay for the screen to come on? If there is, the phone is sleeping fine. If not, and the screen wakes instantly, something is preventing the phone from sleeping properly, thus wasting battery..

Its not really a good second but yeah there is a delay, never noticed it was instant.

As far as I can determine both AOSP and stock email APK have this issue, it hasn't been fixed in source yet. But, I have switched to AOSP so I can only report on results when doing that.

You don't have to be connected to data network. In fact that can be the cause of the whole problem!
If you use email and either
- It gets killed
- you lose network access or it is turned off (a-la Juice Defender)
.. then it goes into this wake-lock state and hangs onto the CPU forever, draining the battery.
Every person I have seen complain about the excessive battery drain was using Email like me.. the most common comments are along the lines of "all I have going is email and..." so I suspect this (along with the Gallery3D issue) is the cause of most everyone's problems.

so if I'm not using the Email app at all (I removed it entirely)
it SHOULDN'T be munching through my mAh?

You don't have to uninstall juice defender. Simply adjusting settings so that it does not force a sync on schedule. Then it actually saves battery again.

I don't have any battery drain (Doc's 7.6.2 JPO).
I use stock gmail app 'cause I only use three gmail accounts with data sync enabled.
I never installed Juice Defender nor ATK...
My battery lasts 2 days.

No, just turning the radio on and off causes the Email app to lose connectivity and go into the wake lock.
Update - my phone burned through only 8% overnight from 11 PM-7 AM. Previously it would burn through 40%+ overnight, no matter what kernel or modem or other options I turned on or off.

Did you roll back the Gallery app?
Also it is possible you have another app with this wake lock problem. Run Spare Parts, Battery History, and change the dropdown to since last boot/Last charge and "Partial Wake Use". Click on whatever 1 or two apps are on top.
If the time listed is more than a small % of the time since last boot or charge, then that app has a wake lock problem.
In the case of the Email app it will easily have a wake lock use time of nearly half of the time since last boot.
Any app with a wake lock is a huge battery consumer since your phone never goes to sleep mode.

I'm not having any major batteries actually ;p I mean, if I can somehow improve battery life by changing some more stuff, why not?
I'm on the Gallery off Market (no sensor issue). on another thread if users are reporting Stock Gallery not having any battery drainage, I might roll back to try it out.

I am sorry for noobness, but how do I do these things you suggested? I cant find this configuration to disable checking mail besides push.
I am using stock email app and my gallery doest have sensors problem. But my cell is draining like 20% overnight (6 hours while cell was sleeping). This is insane and I cant track what is using this much.
PS: I am using Doc rom with cfroot

Open email, go into Account Settings. Under Check Frequency, make sure it is set to AUtomatic / Push. Then make sure you don't have any auto task killers or other things running that kill apps or turn your radio on and off.

I think email is the problem...

automatic/push selection

forgive my noob question but I cant find automatic/push in my email settings at all (it only allows for never, or other time intervals up to an hour). This is on the AOSP email app.

OK I should have mentioned Push is applicable to outlook email only. If you are using some other POP email you can't use push. I am not sure if Push is applicable to IMAP.

using email and settings switch to "Never"
did not seem to encounter this b4.
My data is usually turn off. I only turn on manually when i need to check mails or surf net.

I dont have sensors issue with gallery and I have removed all email programs from my SGS.
Still have battery issues. It drains really fast when data is on and I cant track what is using so much power

Quickest way to determine which process keeps the phone awake

I'm currently running cm7.02 nightly #94 with a color theme.
I can see that sometimes my phone doesn't sleep properly. There are periods of time 1-2 hours long when the phone is awake with the screen still off.
What is the quickest and the most efficient way to figure out which process is doing that?
Thanks.

Spare parts, download it click battery history and them partial wake lock or something. I'm not sure if it still works. It would force close on sense 2.3 don't know about asop

I like using Process Monitor Widget. Download it from the market. Open it up, then hit menu>record. keep the phone unplugged, turn the screen off, and let the phone sit for like 5-8 hours with Process Monitor Widget recording (preferably overnight). Then, stop recording, and hit analyze. It should be evident what is causing the wake lock.

I'm going to second and say use Spare parts, super easy and it will tell you what is keeping the phone awake.

Man best way to tell is to go to the menu and click on about phone all the way at th e bottom and check your battery there is a uptime and awake time if you are having wake issues both of these numbers will be the same even when the phone is off.
Been running synergy nightlys with latest OTA no wake issues for me.

Most of the time it's when WIFI is on it will keep phone awake I noticed this when it's off phone sleeps like a baby. Some apps can do this also but mostly WIFI seems to do it for me on some nightlys depends on the rom tho .

Sorry for the delay. When you have process monitor widget open, if you press menu, one of the options is record. Press that to start recording. Let it sit for a few hours, then go back into process monitor widget. When you press menu, you'll see it says recording. Press that to stop recording, then press the analyze button and review the results.

Phone Always Awake

So, I just went and checked my phone's battery usage and realized it has been awake all day. I'm not sure what's causing this, nor how to fix it. I tried glancing through the forums a bit but I'm pretty busy at the moment and didn't see anything, so I apologize for probably repeating a topic. Oh, I'm running MikG 3.0 with the Less Lionfish 1.4 kernel, Smartass governor and SIO I/O scheduler. Thanks for any help.

sounds like maybe a rogue app. did you restore any apps through Titanium Backup? did you recently download any new apps? How long have you been noticing it? do you have any data syncing in the backround that may be hung up?

app
I think alaman68 is correct. If you reboot your phone, does it happen again? If yes, check your running apps for rogue service. If not, you'll just need to to do trial and error.

Today was the first day I noticed it, and I check my battery usage rather often. I am constantly installing and uninstalling apps, but I don't have anything currently installed that I didn't have before when my phone was normal. I'll reboot my phone and see if it continues.

wipe the cache and delvik when you reboot

I rebooted it without wiping either cache and it has stopped for now. Should I do that anyways? Thanks for the help, by the way.

In terminal emulator, type dumpsys power.

Im having the same problem somehow. I thought it might b android Os that was high but that doesnt come up on battery use...
Cm7

Check to see if you have FriendStream removed, I know MikG will allow this through the tweaks. If it's not showing up in your list of apps, it'll lead to a sync problem that will literally keep your phone on constantly. The only way to fix is to wipe and flash again, then don't remove it. You can try to push it back in through ADB, but that didn't work on my phone. I reflashed, and now I'm consistently getting 19 hours with no tweaks applied. Just a heads up. Without FriendStream, you may see the sync icon in your top bar all the time.

I don't have the sync icon or anything, just the ones on the pic but still awake?
If i do clean flash then nandroid restore, will the problem fine back?
What else can b keeping it awake

I don't have friendstrm or any of those Facebook related apps

Nothing comes up on battery use, its simply always awake

Will this happen even if you shut autosync off? One of the first things I do when flash a rom is remove friendstream, I never thought of a potential problem though.

When you open the app the first line on top says other. Change it to partial wakelocks. Before checking your wakelocks unplug your phone and don't use it for a few hours.

Or an app is waking it up to sync / find location / steal and transmit your data.
Have you tried running Avast ? Locking all the running apps ?

quite strange..
I don't believe apps can turn it on when it's off..so if you turn your N7 off, your alarm is disabled. at least, I'm pretty sure of that.
And, so you watch it turn off all the way? And later on it's on?
Is it plugged in to the charger?
Have you ever watched it for a little while [while you were doing something else, just glancing at it once in a while] to see if it just randomly turns on?
