So i rooted my evo and installed a custom rom pretty much as soon as I had it out of the box. And then started installing apps. And i've pretty much NEVER had a fully charged battery last for a whole day even with very little to no usage of the phone.
A few days ago my friend also got an evo but hasn't rooted it or installed any apps yet. And he is easily getting TWO days or more out of a charge.
so i decided to do a full wipe of my phone, and what do you know, I'm suddenly getting 2 days out of the battery, maybe even a little more then 2 days.
Previously, i had setcpu installed as well as system panel. And i was never able to figure out what was draining the battery. When i looked in system panel the only thing that was using the cpu a little bit was system. Pretty much every other app listed was showing 0.1% of cpu usage.
So i'd like to know if there's a better method to figure out what's draining the battery. Do I have to install apps one at a time and wait a few hours/a day to see if the battery starts going down? or is there a better method?
thanks
I always check the awake time versus the time on. If the wake time is very high that means there is an app acting up.
What I'll do to investigate which app is I'll just go to the little stock battery report thing and look at what is using my battery.
Also, it should be noted that be wary of the facebook app. That thing is a complete and total battery hog. It was draining my battery from 20% over the course of an hour.
I was checking the stock battery report - it wasn't showing me anything useful when the battery was going dead.
right now i'm getting amazing battery life compared to before.
90 minutes since the phone was unplugged and it's only down to 96% and that's with me using it a bit. Previously, it would have been down to 85-80% by now.
I just have no clue at all what was causing the drain. I was hoping there was a better method other then installing apps one at a time until the battery starts draining to figure out the culprit.
There's an app called Watchdog and it monitors the background activity happening on your phone. If some seems to be getting out of hand it will notify you.
I had the same problem I installed Smobile security and it was KILLING my battery. Watchdog was able to tell what it was.
Hope this helps.
It looks like watchdog does basically the same thing that system panel does. and system panel wasn't showing me anything unusual. System panel shows the cpu usage of apps - and none of my apps were showing high cpu usage.
I guess there's really no app that can actually show you the battery usage per app - it can only show you the cpu usage.
You can try SpareParts from the Market,it may help you see if you have a wakelock issue of some kind and its free so no harm if it doesn't help.

actually, the rom i am using already has spareparts in it. I'm not sure what you mean by wakelock though. How do i determine that? What is it?
Just a general question, i have no problem with my devices battery life during useage, but whats annoying me is how much battery life i'm losing when the device is "asleep"!
i can lose between 10 and 25% battery when the device is asleep overnight, or while i'm at work.
this isnt a one off, it seems to happen most of the time, so i'm having to charge it every couple of days, rather then once or twice a week.
is this a general problem, or do i need to do a reset.
thanks
There are many apps found out there (some need root) that can track down what's eating the battery and or preventing device sleep. Google Search app is probably one of the culprits. I disabled it long ago.
If you're not rooted, try to disable some "bloatware" apps in your device settings > applications. .... If your rooted, freeze apps from self-starting using greenify app or remove with Titanium backup app. Just backup them first
I could go on and on, but at least some pointers where to start. Good luck
Have your wifi sleep when not in use. You may have some apps hijacking your bandwidth. You should only lose a few percent overnight...

I have the 8.4, fully stock and hardly a thing installed on it (it's like my 5th tablet for use) and I think its at 50% after idling for 15 days.
only thing that beats it so far is my Nook HD+, which probably idles for 4 months, literally.
having the same problem.
i do have google search in my pages. disabled it , gonna see how it goes ...
whats a good app to recommend that i can check out what is causing my device to wake while it should be asleep?
im rooted btw
Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).
You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.
Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.
Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

On the off chance that you or anyone else can help me understand what's going on I ran a ~10% drain test and made a picture including information from WakeLock Detector and GSam. This drain seems very bad considering the screen was only on for a total of 16 minutes and I lost 8% power.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

Do you have any recommended settings for that app? I disabled something that I think is allowing me to enter deep sleep more, but I have to finish testing. Thanks for the help ratbags!
Oh I see what's the wrong.
Battery usage give me a wrong information.
My fire phone lasting about 5hrs turning on screen.
Very very good !!
Thank you.:good::good:
Five hours is good??

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.
I'm running 4.4.2 Kitkat on my phone. I have been through 3 devices, the first one my screen cracked, the 2nd one kept overheating and my battery life was horrible, it had Lollipop, then the 3rd one they sent me the camera lens was scratched up and now the one I have now I've had for about a month maybe and I get maybe 4 hours of battery life. I have sync off, lux autobrightness which is usually set to night, location stays off, wifi is always on, knock-knock is off. I rooted using Kingoroot the other night trying to see if I can get bettery battery life and downloaded titanium backup, supersu, bettery battery stats, appopsxposed, xposedinstaller, twrp manager, wakelock detector, greenify, amplify, and powernap, I went to sleep and my battery was at 77% and when I woke up it was at 65%. I just uninstalled Facebook, Kik, Facebook Messenger, Instagram, Swiftkey, POF, Accuweather, and Twitter. I go to my battery status and it's showing Android OS 25%, Screen 25%, Android System 15%, and com.androidsystemui 4%. I know that the Android System Processes shouldn't be in the top 4, not all 3 of them. I do have gsambattery montior, bootmanager, autostarts, performance profile, ds battery saver, and supersu also downloaded. Any idea as to what is causing this? It did it a few days ago and I did a FDR before rooting it and I'm trying to get better battery life. I used to be able to get 8hrs of battery life without having to charge it. Please help. I love the LG G2 but this battery life sucks. Please help. I'm new. What can I do to fix this? Would a FDR help?
Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.
My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
