Sigh. My Evo's Battery Life is Rediculous (not typical)

Fully charged my phone night before last and went to work in the morning (9am). I didn't touch it all day, didn't even turn it on. On my drive home at 5pm it was dead, off.
I plugged it in with the phone off when I got home and saw that it was fully charged a few hours later around 10pm and I booted it up and left it alone. This morning it was dead, off.
Looking at the apps that take up my battery doesn't work because it doesn't retain information what happened to the phone prior to the last reboot. Not sure what to do. My awake time matches my standby time exactly. It's obviously a 100% awake time problem but what's triggering this?
I'm on Fresh .3 with absolutely no other mods. I don't think I have any apps that ping outside servers. So what the ****!?
EDIT:
lulz, I just realized I haven't been even able to use the phone in 3 days due to this issue

Something is eating your battery obviously.
Restore to stock and see if you have the same issues.

That's a PITA. This is a clean fresh .3 rom install with only logmein, dropbox and couple non-online games installed. Why is this phone such ****ing fail right now.

Have you removed the Favorites widget? Doing that stopped all battery drain problems for me. Just delete the widget.

First thing to check is if you have a sufficient cellular signal. If you are getting a weak signal it will cause poor battery life. If cell signal strength is not your problem then it is definitely something you have installed on it eating away at your battery. That said check/do the following:
1) Check how frequently you have your accounts syncing
2) Before the phone dies look in your battery use to see what's eating your battery
3) Install a task manager/killer (I use Advanced Task Killer)
4) You don't have to do this one but it does help. I use a program called Startup Auditor to disable startup on apps I don't need to run when the phone first boots (you'd be surprised how many are in there).

delete it completely or remove it from one of the home panels?

the "time without signal" workarounds seem to prove the most effective for me. in addition, reduce background usage and automatic update frequencies as best as you can.
according to this thread [http://forum.xda-developers.com/showthread.php?t=709768] (and link within), HTC has acknowledged some issues and is preparing to deploy a few fixes.

You are running someone else's ROM, there could be a problem with the radio, or a problem with the way it was loaded.
If you are in an area where you don't get signal, you are going to drain the battery, and FAST.
Do you have 4g on but not in a 4g area?

I am...
fully rooted and have fresh .3 as well. I am getting over 30hrs with moderate use and the last hour of that I had everything on to purposely run it down to dead. (was doing a toastch recommeded battery meter calibration).
Took my phone off the charger last night at 7:30 pm. It's 2:23pm and I have 31% left. I have Wifi, BT, and Background apps with auto sync turned on.
I would say you might be experiencing the Motorola cell tower problem. HTC has confirmed that the EVO is not playing well with cell towers that have motorola transmitters. It is causing the phone to use more energy to dial in the tower.
To be sure...
1. Set all apps and widgets to manual update or update once a day.
2. Get rid of the people app or widget from any home screen.
3. Go into Gtalk and uncheck auto sign in. Then sign out when you exit the program.
4. charge the phone until the green light comes on. Don't use a battery meter. The second the green light comes on, go into recovery and wipe the battery stats. Reboot the phone and run it until the battery dies and will not longer power the phone. This does nothing for the battery but does recalibrate the internal battery meter.
5. For maximum life...turn off: background data, WiFi, BT, and Mobile networks when not using. keep screen at 1/2 brightness.
If I do the above and manually update mail, weather, social apps, etc... and only turn radios on when I need them, I can get 40 hrs. out of my EVO and this is under moderate to high moderate use.
One other thing....plug your phone in for 10 minutes. Then unplug it and go into immediate stand by for like 30 minutes. Go to settings>about phone>battery>battery use>cell standby. Time without signal should be very low....anything over 10-15% and I'd suspect that if you did everything in 1-5, you have a towers issue robbing your battery.

I was having awake time issues with Fresh .3, so I switched to DamageControl, and everything has been great. Unplugged this morning at 7, and I still have 75% battery remaining. Better battery life than the Hero or BlackBerry Tour!

I seem to be having the same problem as you and it is quite frustrating. I get a steady 10% battery drain every hour even when its idle. I tried juice defender and setcpu and it is still the same. I turned off all my sync accounts and nothing. I also have systempanel and it doesn't seem like theres a rogue app eating my batteries.I'm going to truth to stock tonight to see if something is wrong with my phone. Did you ever figure out what was wrong with your phone?

AVA9 i get 20 hours a charge
but YES something is eating your battery install system pan have and let it run a bit and check the info id bet its
1 your evo spend a lot of tWOS
2 you have a rogue app eating your battery

Way to bump an ancient thread.

DOH dear god i did not look at that lol

I do apologize for bumping such an old thread, but I feel like this thread has already asked much of what I also wanted to ask but have not reached a conclusion. Therefore I would like to try and solve the problem or provide as much info as I can to solve the problem.
I indeed have installed systempanel and here are the screenshots for the day.

As you can see besides the internet, there is nothing else thats taking up the battery. Also I took this pic after I put the phone on the charger for a bit, it was at ~ 13% before. The battery usage information says a majority of the battery was used by #1 android system and #2 cell standby, it was neck and neck almost, with #3 being phone idle. My weather app polls every 3 hours, my facebook syncs every 30 mins, my htc sense facebook syncs once a day, and I have not configured any other emails except for two gmail acconts, which received probably 3 emails throughout the whole day.
I just used setcpu today, it made absolutely no difference. Same results as yesterday when I did not have setcpu. Thanks in advance for the help!

dude you need to try my setup: superevo and setcpu
i got 7 days of battery using the evo as a simple phone.

Why would anyone use an EVO as a simple phone.
I am beginning to think peoples opinions on moderate use vary tooooo much. The EVO is similar to an unplugged laptop. The more you make the cpu work the faster your battery is going to drain.
It seems some people just dont get that.

I dont get it........BATTERY DOESNT LAST FOR ****!

So i noticed on my stock battery i get about 10 hours of battery life, when im really not even using it at all besides checking it on my breaks or lunch. For instance i had a full charge at 4:07 pm , disconnected and now have a 70percent charge at 5:44..? really WTF is going on with this phone..? I havent done **** on it but browse. I even bought the verizon extended battery and that thing doesnt last as long as i thought, it dies down in about 8-10 hours tops as well.. Is there something im missing here?
I dont run gps often and neither wifi or bluetooth. Just texting and getting online every now and then....
i do have advanced task manager and do notice almost every program running all the time although i kill it when the programs when i jump on my phone....is this normal? wtf is going on with this thing?

Check for things updating frequently like twitter. Also don't kill them apps they will restart using battery to start it. Just let them run, they actually hibernate till needed.. don't close them.. that's probably killing your battery.

There is a lot of bloat ware that runs in back ground unless you root and uninstall. That is the one think I hate about these phones. I wish I could uninstall the bloat ware with out rooting. Anyway download advanced task killer and set it to kill programs whenever screen is blank. It will save some battery life. I get a day out of mine easy and I talk for at least an hour text at least 20+ a day, have it auto check every 5 min for 2 emails and have quite a few widgets running and surf at least 10 minutes...

I was really hating the battery at first. So much that I bought two non oem batteries from ebay. However, since I rooted AND loaded leaked froyo AND loaded deodexed, re rooted froyo leak through koush's recovery, I am getting through the day with 30% or more when I plug back in at night. The only extra charge is in the car dock for 30 minutes on my ride home from work. Try those steps, and rename bloat. Get rid of atk. I get much better battery life without it.
Just my experience, hopefully you figure it out. I'm a fairly heavy user and love this device.

I have had battery issues in the past. Now I am making it through the day comfortably. I am at 12 hours and 45 minutes and have 40% battery left. That is with wifi on all day.

Look. The real issues are simple, the display is quite large and pulls more backlight than it needs. Not only that, but the CPU pulls more power than it needs too. I turned off automatic backlight and set it to the lowest setting. I rooted my phone and use setCPU in order to scale back the processor when it's not needed.
Also, web browsing on a 3G network is much more energy consuming. It's just a fact.
As for the apps, they activate because you have widgets on your home screen. If you want to reduce the running programs, replace unneeded widgets with shortcuts. The less programs running, the less power needed for RAM and CPU function.
What do I get in return for all of my modifications? I can use my phone for about 2 days without having to charge.

I can easily go 48 hours on my extended battery with the right settings... YEs this is with 3G on all of the time.
SetCPU is underclocking or "ON DEMAND", I have deleted most apps that come with the phone that one would never use, backlight is on low usually...
If you are sure that you have all of these settings set and still aren't seeing improvement, go to verizon and have them replace your batt.....

I can go 48 hours on the extended battery and I'm not using SetCPU and I typically leave the screen on auto brightness (though I guess I occasionally turn it down).
Yesterday's usage:
Unplugged the phone around 7:30am. Read emails for about 20 minutes in the morning, checked the weather. Listened to some music on my bluetooth headphones on the way to work, maybe 30 minutes. Started up Appbrain on the phone and downloaded/installed the apps over 3G. At lunch, I listened to more music on the way home, browsed the internet for maybe another 30 minutes while I ate, and listened to music on the way back (all bluetooth).
Showed a few coworkers some of my apps, so another 20 minutes or so with the screen on. Occasional email/text throughout the rest of the day.
At home, I sporadically pick up the phone and browse the internet/read emails/send texts. Easily a solid hour+ of browsing. Played a couple games and downloaded a couple more apps.
When I went to bed and plugged the phone in, around 11pm, my battery was at 50%.
More information about my phone:
- The only radio I toggle on and off is Wifi. Everything else stays on all the time. Wifi goes on when I get home.
- Widgets that update themselves are: a calendar widget, a Google Tasks widget, a sports score widget and a weather widget. All widgets with configurable timers are set to update in 30 minute intervals.
- I have ATK installed but only to let me manually kill processes, it has no auto killing intervals set.
- I am running Launcher Pro Plus. Before I installed LPP, I cleared off my entire Blur desktop - there is nothing on it.
- I am rooted and have removed most of the common bloatware - nothing crazy, just the things like CityID, Amazon apps, Blockbuster, etc.
Hope that information helps someone.

Speaking of extended battery and long life, I just got 34 hours out of mine and it was only down to 30%.
I'm using Juice Defender, toggling data for 2m every 15m AND completely shutting off data when I sleep, 1a-7a.
I don't have a lot of background updating apps either, that seems to be a big thing. After figuring out what works and what doesn't regarding battery life, I can use my phone as I please and not worry about batt life.

This thread is crazy my battery last all day and im on the internet atleast 4 hours a day and receive and make multiple phone calls, and text and stuff [email protected] 12.5 hours with 60% of battery left. I did condition the battery when i first got the phone i let it fully discharge 5 times

Bought the 1750mah extended battery. First 6 days the battery didn't last that long but the instructions did say do 8 full charges which last about 7-8 hours. I did that and over the weekend I saw awesome battery life.
Unplugged at 8am. At 10 pm I was at 40% life. That was with some light web browsing, book reading.
One thing that makes a HUGE difference. Are you in a constant 3g area? If your phone drops to 2g/1g and it can't find a signal, it will burn through your battery like crazy.
My work building is a verizon void and I get virtually no signal. I get in at 7am. By the time I leave at 4 pm, I'm down to 15% battery. I do not use a task killer. I keep my screens to a minimum. The only thing that updates are facebook posts and beautiful widget which updates every 3 hours. I use the smart battery profile.

Don't you a task killer they kill your battery faster. This is not a windows phone, its based off of linix. applications don't stay running in the background, they hibernate so there not using a lot of resources. when you kill them there just going to restart all at the same time, which slows your phone down, and kills your battery. I was getting about 11 hours on one charge using a task killer, now using it more im getting at-least 14-15 hours. plus if you have your task killer set to high it will randomly reboot your phone, even when your using it....

I dropped my task killer and my battery life is now better. I've had my X off the charger for 6 hours and only recently got to 80%.

My battery life is amazing. I left for work around 6 am yesterday with 100%. Through out the day I talk for about 2 hours, used the internet for about 3 hours straight, listed to music for 1 hour, pandora for 1 hour, and navigation for almost an hour. My battery was at 20% at 11 pm.

I have noticed a huge improvement in battery after installing leaked froyo. No task killer here but I do have watchdog installed. Haven't had it activate yet though. No widgets on blur screens and running launcherpro. Love this phone with froyo. Would have returned it otherwise.

SystemPanel shows system using CPU overnight?

Trying to figure out what was causing excessive battery drain on my phone, I downloaded SystemPanel and had it log overnight. I read that when the phone is unused, none of the apps in the "Top Apps" should show over 0.2%. I left my phone on the charger all night and the "system" app sucked up 1.2% completely unused. Apparently there should also be some kind of standby app showing up, and that is nowhere to be seen. I'm running Nero v5. Anyone know what could be going on?

System panel logging uses cpu cycles

In my experience, System Panel is not the culprit when this happens. I've had success with getting 0% battery drain on airplane mode overnight, and always w/SP running. (It's inconsistent, though -- I actually tried it just last night, and Market ended up jacking the CPU all night, even though I had killed Market hours before bed. Don't know why this happens.) I actually leave SP Monitoring on all the time, and generally get (what I consider to be ) great standby battery life.
To the OP: what were the top apps that were running (at more than 0.0%); and were they burning CPU the whole time? If an app/process is running the whole night, it seems to also "trigger" System to burn CPU -- but the app itself is the "real" culprit. (Pls keep in mind I know none of the technical details; but I've experimented a lot w/this.)
EDIT: sorry, just read yr post more closely. To address two more points:
(a) re: the "Standby" process -- this rarely pops up for me, even on the occasions where I do get a totally placid phone overnight w/no batt. drain.
(b) re: I left my phone on the charger all night -- try it without doing this (stay off charger & use airplane mode), and see what happens. I haven't had good luck w/leaving phone on charger: I wake up to same thing -- System jacked up -- and end up needing to power-cycle phone to get System to settle down.
(By the way, I'm totally stock JI6, and so can't address Nero etc.)

The standby process ("suspend") should always be near the top of the list if your phone is truly in standby in a given 8 hour period.
notverycreative - system always uses between 1.9-2.5% for me. It's the system processes and regular apps that you should pay attention to. Once I used Titanium to freeze Media Hub, the DRM Protection Processes, WiFi Calling and some poorly coded apps, my battery life improved significantly.
Here's some screen shots from mine over night.

Alright, I'll try doing all that tonight. I just flashed Bionix V so I lost my data from last night, but I'll try to recreate it tonight. I did get rid of the DRM processes and Media Hub, as well as SNS sync. I never installed WiFi sync for that exact reason.

Just spent the night on flight mode and nothing took more than .1% battery and the battery didn't drain much at all, as the meter read 90% before and after I slept, which was about 6 or so hours. It may have something to do with flashing Bionix, but regardless I am happy thanks everyone!

[SOLVED] Battery drain with data usage on vs. off

Hello peeps,
During the last couple of days I've read up a lot on the topic of battery drain. The reason is that a few weeks ago I could go for days without charging my phone with minimum usage with data traffic and gps turned on, display set to auto adjust the brightness etc. I basically didn't take any extreme ways to save my battery, as I simply didn't need to. But then I flashed Doc's and Stefunel's latest rom, with hardcore's kernel and all that. You know, pretty standard, nothing special. DTJP3 modem, the standard one for Australia. Was great for a start.
But then the horror began, after about a week. I've noticed that the up/download arrows are pretty much constantly glowing up there, and the battery drains in hours! I can't notice that my data usage have gone up a lot though. So I've tried that battery settings wipe thingy and some other stuff. Changed modem to JPY, which is also supposed to work in Australia (Even better from what I've heard). And sure, feels like I might have a bar or two better in reception. But the upload/download is still constantly on.
This is when I tried turning that of. I turned of data usage, gps, bluetooth, wifi, set brightness to lowest and downloaded Battery Snap. So with everything turned off, my battery dropped an average of ~0.5%/hour without usage. SWEET! Then I turned on data usage, and nothing more. It dropped 23% for the first hour, and 13 for the next half hour. Didn't think about actually checking the temp, but it was warm. Like when you use it.
This turned out to be an awful lot of text for just this question, but what could be the problem? Is there any way to check what's leaking? I've got SGS email on push only, no task killer, WiFi turned of, so those can't possibly be leaking, could it?

about 5% per hr here with data on, may be you got something in behind hog the cpu an keep sendibg data

Sounds like an app keeping data connection on. Try kill all apps, look on the services and kill the ones which are not nessesary.

Sent from my GT-I9000 using XDA App

Yes, 1-5% per hr is pretty much what I'm looking for, and had before. It's definitely not CPU, as I've got OSmonitor, and nothing shows up there as hogging it.
I'll try killing app after app through OSmonitor, thanks for that tip.
Oh, and btw, I turned data usage off during night. It has dropped 1% in 9 hours now

That was easy
com.seven.Z7.service is the villain here. Isn't that the SGS email client? Even though I have push? Thought that wouldn't be a problem then...

com.seven.Z7.service kept starting again, but the I went into "Settings -> Apps -> Manage Apps" and killed Social Hub. Voila! It worked. Even though I started Social Hub up again after, it worked. Weird... Or, not 100% sure yet, but so far it works. will check the battery drainage first in a few hours

Good have you have probably found it! One sidenote i have stopped using the sgs email client since i had the problem that new emails werent showing up ... i switched to k9 - you can try this if the problem stays ...

Had the same problem with my SGH-959d (Telus Fascinate). Tracked down the culprit with Droidwall and then found your post. Killed the process through manage apps like you did and same results. Pulling battery didn't work, changing sync settings either so thanks a million for this!

I had a similar problem with my battery graph nose diving. I only realised my data was going through the roof when I started getting 'your are using to much data' text from my operator.
What I found helped was going into Settings->Privacy and turn off 'Back up my data'
Now I get I can go a day without charge. Instead of and hour and a bit... would be interesting to know if it helps you?
(On XXJVO no mods)

good tip about back up... but what do we loose?

A nice tip could be turn 2g/3g on/off when need it. Its a good way of saving battery.

I too am curious as to what id lost if we turn off back up data

Massive battery drain

Hey guys. Recently my battery has been dying at an alarming rate. According to BBS it's from a process called diagnostics.client.Wakelock, does anyone have an idea what could be causing this?
I started noticing the drain after setting up my Galaxy Gear, don't know if that may have something to do with it.
Thanks!

Thanks! I'll give that a shot.

I am facing a huge battery drain as well after the recent update was pushed. I don't have the "diagnostics.client.Wakelock" in BBS but Samsung Push Service was hogging a lot so I turned that off. It was 80% at 11PM and today morning it was down to 59% .. that's 21% in standby mode. Is it not going into sleep mode or is something else causing this? I have almost everything turned off. Any ideas guys? Thank you.

MJ7? (not sure why but like other people remarked - the battery life looks to have somewhat declined - 30-60% less?)

Yes MJ7. I hope this is a bug that can get fixed sooner than later. It's horrible. I just got 1h 37mins of screen time and now I am down to 12%. Just a few calls and some Instagram. Nothing else. Would removing the battery for a while or something help? I haven't installed any app since updating to MJ7 (2 days ago).

I've had this issue with MI7 and MJ7 so the update is not the problem. My guess is me freezing most of the samsung bloat on the phone through Titanium is causing this. Maybe there's a process trying to find something thay I froze?
Sent from my SAMSUNG-SM-N900A using Tapatalk

I fixed it by charging my battery up to 90% then removed the battery and kept it aside for a while ~10 mins and then plugged it back in and charged it to 100%. Now it seems to be normal again. No drain last night. Moved only 1% from 12AM to 9PM. Cheers!

I have the same issue with MJ7 firmware; the phone sometimes doesn't get into deep sleep while the screen is off.
A possible cause of the issue: switch off wifi when data are off.
So now I switch data on before turning wifi off.

Anyone ever find a solution to this? It's killing me.

Same here, my battery declines almos 1% every 5 minutes just texting via Whatsapp and I know Whatsapp is not the guilty. Using Wakelock monitor shows 30% Android System usage with a lot of entries in Gpslocationprovider (even with GPS off and everything on Location settings off), SyncloopWakelock and AlarmManager... MJ7 here too... My Note2 wasn't like this... I finished the day with 5% of baterry after heavy use from 8am til 10pm (including 45' watching videos)... With my Note3 at mid-day I have my battery death!! I can't believe it! and I don't know what is happening (I only have 4 days with my new Note 3) and I have tried almost everything (deactivating) except wipe data/factory reset (I've tried soft reset and nothing)

Anyone ever find a solution to this wakelock?

anyone find a solution?

Delete Google search from system apps and deleted Google play services. Redownload both from play store. Seems to help.

I noted that my GN3 would have great and then poor battery drainage. It seemed to happen right after my first long call of the day. I noted in my wakelock app that diagnostics.client.wakelock was using a lot of time.
I decided to take more drastic action by doing a factory reset and restoring apps one by one. I first used Kingo Root to root my GN3. I had to uninstall Kies and the Samsung driver to get the rooting to work.
Then I backed up with Helium and Titanium backup.
After a factory reset, my battery usage was about 0.2 percent per hour. I use only data and no wifi.
I have now restored most of my apps and still have 0.3 percent per hour usage. I have not updated any Samsung or ATT apps.except for ATT code scanner. i have not "used" any of the google apps except for gmail, search, google+ (signed out). Google music is turned off.
Diagnostics.client.wakelock still shows up but with low time now.
After twelve hours, the GN3 is at 96 percent including a two minute phone call and email updates.
------
After a long phone call, I once again saw my battery usage increase and stay up after the phone call.
-----
I re-started with a factory reset and only restored the minimum apps that I use to browse, email, text, phone, and backup.
So far it is performing well in battery usage.
I will be adding more apps until I find the one that breaks the good performance.
-----
So far I have been able to make it through 24 hours using only TEN percent battery usage. I have added TextPlus, BofA, drippler, Helium, Titanium Backup Pro, CPU Spy Plus, Wakelock Detector, System Tuner Pro, Battery Monitor Pro, AutoBluetooth, Maps, Youtube, YP, Total Commander, Visual Voicemail, Quick Boot, Root Checker, Turn Off Screen. Everything else is stock without updating AT&T apps or Samsung apps.
I am seeing an idle usage of less than 0.3% and that is with two widgets for Battery Monitor and System Tuner. They and Textplus use up the most power. I also talked on the phone via bluetooth for about 30 minutes.
I still get the diagnostic.client.wakelog but only getting about 5 percent awake time.
-----
I did another factory reset. This time I did not allow any app updates.
I installed Titanium Backup, CPU Spy Plus, Wakelock Detector, Battery Monitor Widget Pro.
I have not seen a diagnostic.client.wakelock at all after one hour of use.
-----
I added TextPlus, System Tuner Pro. I put the widgets to System Tuner pro and Battery Monitor on the home screen.
I have not updated any apps since the reset.
I have counted about 7 diagnostic.client.wakelocks for a total of 4 seconds of wake time. My wake time percentage since yeaterday is around 1 percent.
I plan to update apps one at a time to see which one kills the battery usage with wake locks.

I just added AT&T Visual Voicemail, PayPal, BofA, and Evernote to my GN3.
The diagnostics.client.wakelock started climbing and keeping my phone from sleeping.
Uninstalling the four apps did not help.
I think that the problem is with the Visual Voicemail.
----
Factory reset my phone and am back to 1 percent wake state and very low battery drain.
----
The cause of the bad wakelock was due to restoring APP+DATA in Titanium Backup. I did that to save setup steps.
I had restored BofA and Shazam with data and the wakelocks started up.
After I factory reset again, I installed apps the normal way and have been seeing a 0.3 percent use per hour.

Samsung's own software is most garbage in my opinion.
If you use ChatOn and Samsung Hub, etc, disabling this may have an impact.
Here's how I've solved the problem with this pig of an app.
1) go to application manager under settings.
2) go to the "ALL" tab
3) find that "samsung push service"
4) uninstall - this will only uninstall the updates. Once all the very useful updates are gone, the option changes to disable.
5) disable and good riddance.
On a side note, search for this on the playstore. the reviews are hilarious.

Nothing I had tried up to today has fixed my battery drain and diagnostics.client.wakelock issue.
However, today, I got a software update OTA (nb4) on my phone and it appears the problem is fixed.
