EVO lasted whole workday - now how do I get it to last ALL DAY?

ok, I'm in a great mood, I FINALLY got my EVO to last from when I leave home to when I get back home with normal usage (no point in only sending texts and short phone calls - if that's all I'm gonna do I coulda got a razr!) but here it is including settings and all with usage details included.
ROM: Damaged Goods 3.5
Running: Advance Task Killer, Battery Indicator, Voice Dialer, Call Filter, Handcent SMS, and google voice just WOULD NOT stay closed!!!
Settings: Auto-sync off, automatic brightness, haptic feedback is off, background data is off
Other: I charged with an external charger that I got off of ebay, so the battery had a good charge to it
Usage Details:
1:59 pm turned on wifi and unplugged the phone
1:18-1:19 short phone call, dropped to 98%
1:47-2:11pm web browsing. Battery dropped to 91%
2:25-2:26 quick facebook check, battery dropped to 90%
2:43pm - checked e-mail, battery dropped to 88%
2:54-2:56 - 2 min. phone call. no change in battery
3:04-3:33 - turned off wi-fi, played some pandora + web browsing. battery dropped to 77%
3:40-3:41pm - phone call. no change in battery
4:15 - battery at 75%
4:16pm - internet (checked e-mail and facebook status)
4:58pm - battery at 69%
5:00pm-5:03 - phone call. battery at 68%
5:04pm-5:09 started playing music and doing the transformers movie puzzle
5:09-5:11pm - phone call.
5:11pm-6:10pm - continued music and transformers puzzle, let a couple people that stopped me asking about the phone play with this and that feature, did a 4g speed test (over 7mbps btw) and other things.
6:10pm - 49%
6:11pm - 11:08pm - phone placed in airplane mode while I'm working
11:08-11:42pm - picked up phone at 39% battery, then continued playing music and transformers puzzle
11:42-12:27 - phone call. dropped battery down to 10%
1:02am - battery down to 8%
now - 1:25am, battery still on 8%
Froyo has definitely improved my battery life, I used to couldn't get this type of battery life out of my EVO. Oh and here's the screen shot at the end of it all to prove the phone was actually USED, and not just sitting around.

to those that dont' know, when you see screen shots with a high percentage of phone idle and cell standby it means the person isn't really using the phone, just letting it sit, or only sending a text or something like that. Think about it - how much use is someone getting out of a phone if 20+% of the battery was used on IDLING/STANDING BY?
I think I'll try it again tomorrow since I have a longer shift, and thursday since I'm off and see if there's any difference.
The point of this post?
I wanna get even more tips to see if I can get more life out of this battery.
where are the people talking about they get 2 days' battery life out of it?
give me some tips to get to that level!!!

You could use setcpu to underclock the phone. Also maybe you should stop using advanced task killer as many people have mentioned on the board it isn't off any use in froyo it may actually harm battery life. I think the battery indicator may also be a potential battery drainer. You should just install the battery percentage mod.

Get the 3500mah Seidio Battery. You will never have to worry about your battery again.

here you go two websites that have my phone lasting from 7am - 11pm with use
1 - http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
2 - http://www.techhackz.com/2010/06/how-to-increase-your-htc-evo-4g-battery.html
the overclock widget and the settings is highly important I can take my phone off charger and 20-30 minutes later after a few txt messages I still show at 100%. I do turn off my 3g but I do run wifi... Try it out

Some of these people might not agree with, but I’m now pulling over 20 hours (possibly even more, I recharge when I get to around 30% battery) with heavier usage than you, exchange set to “as items arrive”, beautiful widgets set to sync weather every 2 hours, data always on, and no airplane mode at all.
1 – lose the task killer. Let things sit in the background. If the background items aren’t set up to sync, then the amount of cpu and battery they’re using are negligible. You actually might be wasting more battery and cpu trying to keep them killed.
2 – uninstall all stock apps like news, stocks, peep, talk, etc
3 – try the BakedSnack ROM, or at least his Baked1 kernel on your current ROM – his built in underclocking helped me out enormously.
4 – if you’ve flashed a bunch of ROMs lately, you might want to go through the Cyanogen’s battery recalibration process
You might also want to try setting up some SetCPU profiles, I don't think it's needed with BakedSnack, but it works wonders on other roms.
Also, your note about "how much use is someone getting out of a phone if 20+% of the battery was used on IDLING/STANDING BY?" is a bit off - I think your percentages are so low there due to your 5 hours of airplane mode. Can you post your uptime and awake time? That will give you a much clearer picture of usage.
And this part is a personal pet peeve of mine - if almost half of your 12 hours uptime is in airplane mode, that's not something to be proud of. it might be better than what you had before, but people are getting 10+ hours without airplane mode - if you have to cripple your phone to get good battery, that shouldn't count.

I think basically getting your phone to be underclocked when its idle will be the biggest help. The Overclock widget lets you set your processor speed. I am also running stock rooted 2.2 with all the garbage apps removed. I ran mine both ways with wifi and 3g on all day and wifi and 3g on demand. I have gotten very good battery life since adding OC. I agree that you should use your phone as normal and make your decision from there... but underclocking seems to be the way to go

I HAD TO put the phone on airplane mode for the simple fact that my job has a very low signal (I think Kroger INTENTIONALLY blocks cell phone reception because I get a full signal outside, almost no signal inside, and it's like that at EVERY kroger I ever go to!) and if I don't put it in airplane mode, my battery would have drained extremely fast.
I don't have the up time and awake time because I didn't think to do a screen shot of it.

the alternative is keep it off of airplane mode and have my battery die off in 2-2.5 hours. Yeah, I think I made the right choice in that instant lol, usually I don't use airplane mode except when I'm sleep

If you can flash an undervolted kernel, it makes a big difference. No task killer, and I wouldn't go with automatic brightness, it uses too much battery for my taste.
Anyway, I'm on CM6 with Snap kernel 5.01 and just got 22 hours 15 minutes with 30 minutes of phone calls, an hour 15 minutes of BT stereo streaming, approximately 1.4 GB of file downloads overs wi-fi, a good 30 or 40 text messages, and a bit of gaming, emails, web surfing, etc, where the display was on for 4 hours and 11 minutes... I was down to 4% when all done.

Setcpu is probably a little more complicated than Overclock widget, figuring your a noob thats why I suggested that but it has been working great for me. To remove apps you must be rooted and if you are you can use root explorer.

depends on the rom - but titanuim usually works. Just don't uninstall any of the stock weather apps - i've heard those can cause issues if you unistall. Makes sure that they're not set up to sync though.

sort of, it's a bit more advanced, and allows you to set up profiles. There are enough "SetCPU Settings" threads out there, that you shouldn't have too many issues setting up profiles. Again though, depending on the rom/kernel, you may not want to use either.

not quite - it's not just that your phone is doing nothing, those items also show that they're waiting to do something. In arplaine mode they're not even waiting, so the percetages will be much lower. I don't think I'm explaining this well, but by putting your phone in airplane mode, its telling standby and idle to stop being ready, and basically turn off, so of course the total percent will be lower.

That makes perfect sense - what I was really trying to say is that if you're putting the phone in airplane mode for that long, your battery time should be MUCH better.

not sure what you mean here - you can find uptime and awaketime under settings in about phone under battery. was really just curious about the numbers not necessarily a screenshot, although you should be able to a screenshot of any screen if you wanted - try shootme from the market. - edit: just reread what you wrote, I misunderstood what you were saying

[Q] Android OS Battery Drain

In the last few days, I have noticed that the process "Android OS" has been using maximum battery life (about 16-35%) and has also been consuming large amounts of data.
The only thing I have done recently is allow the facebook app to upload all pics from my mobile.
Any connection? FYI, I have not added a Samsung account.
Apologies if this has been answered earlier by I did search for it.

what version of android are you running?
what ROM? what kernel?
how long ago did you start to notice this?
is it a constant issue, or does it fix itself after a reboot or something, or with data connection turned off?
do you use google now?
if you are on the jelly bean 4.1.1 version, did you update OTA or odin? just curious, probably not related anyways...
what recovery are you using?
just trying to get some info before i help. many things in the android OS can be directly or indirectly related to each other but still have a side effect on battery life.

16-30% in general has been relatively normal on JB. (Usually between 14-18% is where it settles to)
Keep in mind that unless you are at least halfway through your batt cycle its going to be higher. If you're at 90-95% batt it can be much higher, just due to percentages and battstats being reset.
Not sure why you didn't find anything though, this has been covered a great many times in the past 6 weeks! Did you look at what the top processes are under Android System?

I had installed root66 prerooted JB rom. When I noticed the problem, I installed stock ICS through odin, updated to stock JB then rooted again but the problem continues.
I have been noticing this for about a couple of weeks. Restarting doesnt help but I havent yet tried turning off data. Will try that and let you know.
Yes I use google now.

Is this something peculiar to JB? I didnt see this in ICS. The top processes currently showing in the battery stats are Android OS: 28%, Voice calls: 17%, Screen: 11%, android system: 8%...
Is there anyway to check exactly which app is using the battery and data which is showing as Android OS?

Odd... mine is usually only around 10%

Mine generally sits between 11-14% depending on use. But it can show 30+ if you check it at certain times.
For example, if you've fully charged the battstats will have reset. If you reboot the phone it will kick off the media scanner which can run for a while (this can also be the cause of it heating up for a short time). So once its complete it will have used a rather sizable chunk of the overall battery use. Since it usually doesn't run again, the percentage will steadily drop as other processes use the battery.
I know we aren't really discussing the media scanner, but I use it as an example that is pretty easy to see if you watch it.
Android system has a lot of processes which are listed under its category so depending on how each person uses their device it can vary a bit. Most screenshots of 'normal' reports that I've seen usually are around 14-18%. For me its lower, but I'm pretty sure I don't use mine the same way others do. There are times though where it can go higher for me, depending on what kinds of stuff I'm messing with or testing out.
I believe transferring large amounts of data over mtp is one thing that can cause it to go up...
Hope that makes sense.

my phone just started this last night. i took it off the charger around 11 last night (100% charged) and it woke me up at 3:30 with a low battery indicator, i checked task manager and nothing was open battery stats showed that android os was at i think 38%. i put it on the charger this morning at around 9 am because it had died fully. it's now 1 pm and it's at 95% charged, typically it takes only a couple hours to charge. my phone is fully stock running jb.

What kernel/ROM and version of recovery are you using?

You can track data consumption of Android system apps via Droidstats
You'll be able to know wether it's Google Maps or any other service that uses data

I am fairly confident I've tracked it down to the touch sounds. Sounds dumb I know, but I believe they are wake locking excessively. I have much better results with ANDROID OS drain with them turned off. Interested to see if others do too.

Hey there,
im having a similar issue with my Google Nexus 10 running stock Android 4.2.2 (fresh install of factory image and then manual update with ota update.zip).
Here are two screenshots (didnt want to include here because they are HUGE and I dont know how to resize them in forum "code"):
One
Two
I havent been using it much the last days and im a little spoiled by an iPad 2 standby time so this is not very acceptable
I'll try Droidstats and see what I can make out of it.

Looks like you haven't used the tab (screen time) that much over the two days, making Android OS seem overtly guilty.
Try disabling touch sounds -- settings-sounds- touch sounds
Then let us know. I am convinced that is the culprit of the wake locks, keeping the Android OS (kernel & drivers) high and eating battery.

Sorry, forgot to mention it. I have them disabled since i own this tablet (and I checked it again).
I wanted to try DroidStats, but it seems to be an app for calls, sms and data
Can you post a link to this app (if its allowed )
EDIT:
Yesterday a friend of mine showed me the battery stats on his Galaxy S2 and had almost 40% "Android OS".... but he has never had better battery life. I start to think that (because of the percentage system) the built in battery tools are almost useless
Is 4 days a normal standby time for the Nexus 10? That would be very bad in my opinion.

I've just started seeing the same thing with my Galaxy S3 (Samsung issued ICS, rooted). Normally the battery will last around 24 hours with light use, but currently it's draining from full to warning level in about 4 hours with the screen mostly off (wi-fi, bluetooth and GPS are off at the moment). Touch sounds have been set to off from day one.
Yesterday, the culprit looked to be Beautiful Widgets (around 38%) so I turned some of that off (weather update animations, etc) but I'm still getting the same drain speed - now showing Android OS 26%, Cell standby 22%, Android System 15%, Screen 11%. Not sure if I trust the results though, the BW issue from yesterday could have been a red-herring.

[SOLVED!!]
i have this problem with my galaxy grand phone ,the battery discharges in 20hr , default OS was 4.1.2 official samsung , i changed my rom into a slim custom rom based 4.2.2 , but the battery has same problem again , Android OS battery Usage Was 80% !!!! and screen usage just was 9% !

[Q] Battery drain on Note 2 after 4.3 update

Hello
I have had a massive battery drain problem on my Note 2, a couple of days after the 4.3 update. While being idle during the night it loses 25% to 30% of its battery and while using it I can literally see the percentage drop. I have tried everything that I could find on the net. EVERYTHING! Nothing worked. These included: Factory reset (twice), letting the battery frain completely and then recharging it while the phone was switched off, switching off all sync,disabling bloatware including KNOX components (the actual KNOX app is not installed), installing only a few apps after factory reset, using Gsam, Wakelock detector, Deep sleep battery saver (which could not make my phone sleep), no GPS, no 3G, wifi on only when needed and more besides.
The phone is only one year old and unrooted. On 4.1.2 it had a beastly battery performance of almost 1.5 days of normal to heavy use, with 300 apps on it. Now it cannot go for more than a few hours with the same use.
I cannot say for sure but it seems to me that the drain is the same when it is sleeping and when I am using it. Wakelock has given me a 75% awake time even though I only use it for 15-20% of the day at most nowadays. Battery settings show everything normal, or at least I think so, eg Screen 35%, Android OS 15-28%, Voice calls 10%, Android system 5-15%, Cell standby 7%, Device idle 4%, Media server 4%. The batttery chart shows a constant steep drop all the time.
The problem started one day when the Media server went mad consuming 50% of the battery. After I did the factory reset it has never again been a problem but the drain still persists.
I have also read that it's a mess up between syncing of Samsung apps and Google services, but I have no way of verifying that.
Can anyone help?
Thanks

I had the very same problem until yesterday myself but think I found a solution on the web.. Uninstall Google Search and Google Play Services and the goto the Play Store and wait for them to reinstall and that's it....! As I found that there is a bug in Google Services (Nlpwakelock and Location service)
Hope this helps...?

Download wakelock detector from the play store. It detect which app is waking your device (both screen and cpu) by list.. Then download greenify from the play store and herbinate (greenify) upper most apps from wakelock detector. Hope you can solve your problem

Thanks. I already have Wakelock Detector on. I mistakenly wrote "defender" instead of detector on the original post. It gives me Viber and Messenger as the most active wakelock apps. But they both were not installed when the problem started. Besides, on the 4.1.2 they created no problems. In essence I believe that Wakelock Detector cannot help much. Whatever this problem is , it is well hidden. Thanks for your interest and help anyway. Much appreciated.

Which kernel you are using? And also i recommend using Greenify. Widgets usually eat a lot of battery, I went from battery lasting only 8 hours to get my battery use only 30% in 8 hours.
What i did: installed wakelock detector, gsam battery monitor and better battery stats.
Monitorized the wakelocks.
Applied greenify to the apps which were waking most
Removed widgets which were waking alot
Installed Toggle 2G.
Kernel settings: 200-1600mhz | zzmoove | AFTR+LPA | Multicore power saving (SCHED_MC) = 0 | GPU = stock settings
Works like a charm for me. Hope it helps! Any question, ask!

I've read all sorts of things about this problem since I updated and got hit. I have too much app data to lose by trying the factory restore (which by all accounts shouldn't change anything anyway since you'd still be stuck with 4.3)
I finally decided to try the age old blackberry cure-all: "if in doubt, pull it out" (the battery). Since the entire issue seemed to be related to battery caused problems (ie slow charging, fast drain, etc) it made a lot of sense.
And it worked.
I think the main reason this isn't more commonly tried to fix issues on Android is the same reason I didn't try it earlier. My case is pretty serious and isn't easy to remove. I'm glad I did take the time to take the case off though or I could have ended up wiping my phone.

Thank you for the suggestion. I have already taken the battery on and off several times. It had no improvement. The phone is only a year old, that is why I don't believe the battery is the culprit. Besides, problems started only after the 4.3 update. Before that it was working perfect. Too much of a coincidence.

Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.
As I said, I've read all sorts of suggestions, many of which don't work for everyone (such as the factory reset) - this is hopefully just one more thing for people to try before they end up wiping their phone in desperation. I mainly posted here in the hopes that others with this issue that may not be forum members can get some more suggestions.
At least for me, wakelock and all the other diagnostic tools at my disposal showed nothing different to before the update. Many other people have found that the Android System is using a lot more of their battery than normal or some other apps are involved - if this is the case, it's likely to be a combination of things causing the issue (the firmware, the drivers, apps, hidden Samsung processes, etc).
Also, for what it's worth, I found that Knox supposedly wasn't installed (when I find it in the apps list, the button to install it is showing...). But it's showing in the list of apps so it must already be installed. I dug through the list of running processes (had to show the system processes too) and I discovered that several Knox and some other new Samsung processes were indeed running.
One other quick tip - If you wanted to check/tweak the 'developer options' and can't seem to find it any more, that's because it's now hidden since 4.2 - go to 'About Device' and tap 7 times on the Build Number. I tried disabling all background processes however it seems this only disables application level processes, not system level processes but if you've tried everything else, it can't hurt to try playing around with some of the options in there.

Thanks mate
I think you are right. It is probably a combination of many things. I have opened the Developer options some time back. The one thing that I do for sure in there is limit background processes to 4. Besides that I don't experiment much, exept maybe to change transition animation scale. I am actually thinking of rooting the phone and downgrading to 4.1.2. It was just fine before. I can live without the 4.3 add ons.

The only battery apps on my phone are the 3 mentioned above, so I don't know what the battery monitor that keeps my phone awake is. The drain existed before I installed these apps. I have read that Chrome could prevent the phone from going to sleep but it is disabled on my phone.

I faced same battery drainage issue, after installing wanam kernel and freezing all bloatwares through Titanium Backup. I'm satisfied with my battery now.
You can try.

Here is detail-
Disable sync always, enable when needed.
Disable wifi always scan from settings
Display set to auto
Uninstall apps of playstore you rarely use
Use widgets on lock and homescreen as less as you can (I don't use any)
Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-
profile: normal
Governor: pegasusq
Scheduler: cfq
Don't touch other tweaks, hardly you can tweak sound boost.
THIS GIVES ME A SATISFIED BATTERY STATUS.

[Q] [Battery] Duration and Strange Android system behaviour

Hello everyone!
I own a LG G3 D855 and from the moment I bought it, I've noticed problems regarding battery life. After some resets, the store changed my battery. Despite this, it remained more or less the same. I usually never pass 3 hours of screen-on-time (no gaming!) with a full charge. After that, I considered it was due to the 2K display and reports around the internet talk about 4 hours with this phone, so I became thinking it was quite normal to have this battery life (asking your opinion, guys). Notice I usually have wifi on; 3g, nfc and gps turned off.
However there's a second problem. Sometimes, at random days, like it happen today, I get android system using more battery than the screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I'm avoiding sending it over to the warranty, because I'll be 30 days without the phone and not sure they're figure out the problem.
PS: I'm running stock Lollipop, haven't rooted yet. Same behaviour when I had 4.4

I am pretty sure it's a software issue. The best way do diagnose them is to get root and install BBS (Better battery stats). It allows you to see everything - from cpu states to wakelocks and alarms.
If you don't want to root your phone, then your best bet is to reset your phone (Via recovery or via "Settings->Backup and restore" without adding a google account at initial screen (Or selecting "Set up as new device"), and then add it manually via "accounts and sync". This way, only calendar/contacts/bookmarks/etc will be restored to your phone, not settings. Then install mandatory apps (the less, the better. Preferably none at all...), and see if your battery life has improved. If it did, install apps in small batches and see which one affected battery this much.
About usual battery life:
"
Well, I too am getting around 6h sot on medium usage.
Setup used:
20% auto brightness. Apps report that phone stays 70-80% of time in "dim" state, 20% of time in "dark" state.
Constantly on: 4g, Bluetooth (paired and connected with headset), location services in high accuracy mode and sync.
Constantly off: nfs, WiFi.
Software:
1) Running in GCM push: Aqua Mail, Vkontakte, Google+, hangouts.
2) Running services: Google play services and headset application. I also use Poweramp which streams to Bluetooth headset for 1-2 hours a day.
3) Disabled/Deleted software: Google maps (It's insane wakelocks consumed battery back in ics era... nothing changed since then, lol), all other Google apps except search and Gplay, TAction, LG Email, LG MLT (I already disabled it by not agreeing to their policy, but just to be sure...), frozen LG Music (the widget too), LG Files and LG SmartCard service(I use Nova Launcher, so it doesn't work anyway). I set the location in Weather app manually, because in auto mode it tried to lock onto GPS signal each time i unlocked the device, which caused minute-long GPS wakelocks in subway.
4) I do not use Greenify or whatever. I cure the disease, not the symptoms - so i simply don't use apps which create a lot of wakelocks/alarms or do a lot of unnecessary background activity.
I use BBS (Better battery stats) to monitor behavior of new apps.
I get 5.40 to 6 h of sot, depending on usage. Using Twitch/YouTube/downloading roms drains battery in 4 hours, especially if signal is bad. Music/web browsing/minesweeping + 20-30 minutes of GPS gives me 6h of sot.

Thank you! I've hard reseted the phone and the battery seems the same or even worse. But I've configured the google account right away, despite having selected "configure as new phone". I'm gonna try to hard reset again and only configure it manually afterwards and see if it improves. If it doesn't, does it mean I might have a hardware issue?

It is possible, that is why we are trying to rule out software issues first. If stock 20H rom (this version's battery life is noticeably better than others, i recommend installing it), without Google account and user-installed applications is still losing battery like crazy then yes, you should go to service centre.
And yeah, after reset and setup leave the phone on charger for several hours (3-4 at least). May help in some cases...

I've followed your instructions and hard reseted the phone, manually configured the google account afterwards and installed zero apps except for GSAM battery.
Got total 8h battery at 60% until now but mostly standby. Used the phone for web browsing (Wifi). Everything else turned off. Around 1h sot, 60% battery left. Is this normal?

No, it is not. Android system is keeping a big wakelock on something... "Better battery stats' with root enabled can show you what exactly is keeping phone awake.

Is there any way to obtain this information without rooting? Because in my area they are quite picky regarding rooting when it comes to warranty :/

No, from 4.4 onwards that permission was moved to "system apps only" category. And you can't install BBS as system app wout root...
It's quite easy to return phone to full stock. Just flash stock kdz with CSE flash - voila, your phone has never been rooted.

1) Virus scan mobile wakelock. It's McAfee, and it's baad anti-virus software - delete it via titanium backup/system apps uninstaller or whatever, and never use it again.
Also, disable google's inbuilt apps checker. It can be disabled in "settings->security-> check apps" or in "Application drawer->google settings->security-> check for..."
2) Facebook. It sucks your battery. Seriously, google for it - it's very badly coded. People usually delete/greenify it.
Kernel wakelocks are not truly "wakelocks" on this phone, so don't worry about them.
That's all the info that i can extract from these screenshots.
Delete McAfee, disable google apps checker, delete/freeze/greenify Facebook and it's messenger, then report back. Battery life should drastically improve.

Yesterday my battery life got amazing. Drained 50% with 1 h sot before deleting the antivirus and got more than twice sot (plus 2h7min) with the last 50 %. But today is goimg nuts again... Found two strange things: android phone with +700 wakes and another even stranger thing: bluetooth turns on and off, no notification, randomly... :/ bluetooth is BT, right?

Battery life got better but I do still have problems. Yesterday I turn on GPS because I needed it. After that I turn it off but google maps kept apparently kept the GPS on. Still, today I froze the app with link2sd, but it just kept counting as if the GPS was on with the battery as being on (+3h lol).
With the BT not turning off according to the video, I starting to wonder whether there is any problem with the Snapdragon that doesn't allow me to turn GPS and Bluetooth really off. It also doesn't make sense to me the charging graphic --' it was unplugged the whole time.
Please help!

2) Maps are broken since 4.0. Delete or freeze them and use other navigation software. Or make it a user app and greenify it.
If you really need them - there are guides on how to prevent their autostarts.
3) Charging graph is empty, meaning that is was unplugged the whole time.
4) Bluetooth turning itself on? Hm, never had that one. Besides, bluetooth use very little power while it's not searching for devices or actively transmitting/receiving something, so you shouldn't worry about that - for now, at least.

1) I found a tutorial saying to enter hidden menu in lg g3 and disabled fast dormancy from there. It solved the wakelocks. Is that equivalent to your suggestion?
2) I'll just uninstall them and install Here. I like it more anyway.
- I am figuring out this battery problems in v10a but I will eventually want to update to lollipop (rooted version as I need to get rid of McAfee). Do I need any special precautions or just install twrp and then flash the rooted lollipop?
Thanks!

1) Com.android.phone.
Press on it. If you see ACTION_CHECK_NETSTAT - then it's fastdormancy. Add
Code:
ro.ril.fast.dormancy.rule=0
to your build.prop and reboot

I have tried doing partition wipe cache and disabled most apps under auto start manager, unable to figure out what is causing this issue
I have no other issues on Asus Zenfone 2 and it is probably the best Android phone I have ever used, just this battery drain issues is irritating.
Lot of Zenfone 2 users have logged this issue on Zentalk forum but Asus support seems to be clueless about it, recent firmware update also failed to address this problem.

Me too
I think it depends on wi fi...
When I'm at work ZenFone connect to various AP and the battery drain is heavy....
But when I'm at home the battery seems to be normal, I can finish the day with 20% of battery from 17 to 21.
I see the battery is longer on 3g/4g than when i'm at work on wi fi

I think Zen Motion in settings specially touch gesture is one of the causes for battery drain issue...

Probably...but when I'm on 2.17 I don't see this battery drain....and I always have gesture, double tap to wake/sleep and zenmotion all gesture.
I see the battery drain increased when Asus have changed power profile

'Wifi Scanning always available' may cause battery drain. Recommend to turn off in not needed. To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. If battery still draining, recommend updating firmware to latest version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Hi Frank,
Regarding the Wi-Fi always on thing... Whenever I turn it off of always turns back on automatically.... Any advice.. I already am on 2.19 BTW..

Apologize for the delayed response. Strange, it shouldn't turn back on automatically. After latest firmware is applied, recommend doing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

Frank have you heard any rumors on if asus is working on the 5.1.1 update. The issue of Android us chewing up battery is a widely known issue for lollipop 5.0 and it impacts many different devices. Every thread I have read regarding this specific issue states that lollipop 5.1.1 resolves this issue.

Pathetic battery back up on ZenFone 2, hardly getting 3 hours screen time these days

My battery stats still reporting WiFi use when I have turned WiFi off and disabled always scanning. I don't get it!?
Edit: just figured this mystery out. It's because I had location set to high accuracy. If you set it to high accuracy or battery saving it scans WiFi even when WiFi is off. Put location to GPS only for the last ten minutes and voilà - no WiFi use in the battery stats

Spoke to soon, WiFi came back again on battery stats!???

Use better WiFi on/off by Chamonix. There is an xda thread for it plus it's available on playstore.

Do you see any major results with that application?

I read a lot about awful battery and screen on time before buying the zenfone 2. Surprisingly though with a bit of tweaking this has been one of the best phones I've owned in terms of battery life. I could have easily gotten 10 hours of screen on time i believe if I stayed in an area with stronger reception and turned off some background services like GPS. Here's some screenshots for anyone interested

You have 551 or 550? On what software version are you? And what do you mean with "bit of tweaking" I'm using heavly Amplify and Greenify, and I can get 4-5 SOT more or less..

I'm using the 551 with the latest .22 update. I'm not sure *exactly* what I did to fix the idle Android OS battery drain but I have underclocked to 2.0ghz, zen motion stuff is turned off, GPS is set to battery saving mode, all the stuff under Google settings >security is turned off, Asus cover off, detect battery draining apps in battery settings is off (its not very efficient as it just checks what is running in background, regardless of battery usage) and some more stuff that I can list later on when I have access to my computer

hmm, Well for screen on time Underclocking should help the most. If you don't do any heavy gaming you can set it down to 1.8 without noticing a performance hit ( you could probably take it down to 1.5ghz but I haven't tested that thoroughly so there could be an impact). I use noop as the I/O scheduler but that probably doesn't make a difference. I don't use greenify but I do use servicely. I also stay far away from facebook and the messenger app as that has always caused me crazy battery drain but I know those are apps alot of people would rather not delete so its up to you. I use balance mode in power saver and also use Asus' built in auto start manager to disable most things at boot I don't need. Another thing that helps with wakelocks is to make sure you open the google settings app after you boot ( you dont have to do anything, just open and close. I don't get it either) it works for many people including myself.
Other then that I can't think of much else I do. If anything else comes to me ill be sure to let you guys know
