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?
Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

ok thanks let me do some reading.
Also yesterday I deactivated the SIP app and that helped of course. Still strange that the app consumed to much less power on Gingerbread compared to CM10.2
Thanks,

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration
That sounds very good, let me try that!
I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.
Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

Thanks ... yeah well did not really expect it, but when you're desperate
At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!
Hi. I'm having a problem with my G Pro Stock Kitkat. After using a battery calibration tool, I suddenly experienced battery drops on my phone. From 100%, i checked the battery settings or status, and it says that I only have 3-5 hours to use my phone. I think it may be incorrect. After some minutes, I see my battery percentage continuously dropping like crazy. Could someone help me fix this? Thanks in advance.

We're going to need additional details in order to diagnose and possibly troubleshoot the battery drain. First and foremost we need to know which particular apps you often use on your phone. From there we'll need to see which apps consume battery while the screen is on and youy're on your phone, and which ones continue to drain while screen is off. I recommend you download battery monitor apps such as GSAM battery monitor (include also the root companion), as well as either wakelock detector or better battery stats. With those apps we'll be able to sense as well whether system processes contribute to the drain.
Drain your battery, have this apps installed then full charge your bat. Once full charged begin monitoring then send screenshots once battery is about to run out.
And also, battery is automatically calibrated by android so battery calibration apps are quite redundant.
Hello guys,
I'm in a little trouble right now. For past two weeks I'm experiencing high battery drain on my HTC M8. I'm running Android Revolution HD 10.2 for three months and I've never had that much battery drain as I'm having now. For example, I unplug charger in the morning after all night charging and after 45 minutes (screen off, lte off, WiFi, bt and stuff also off) I have left only 92 % of battery.
What can I do? I appreciate any help and I'm ready to post all data you need.
Best regards,
pablo7890
Since you've been on the same ROM for 3 months, I suspect its some app or mod that you applied recently.
Otherwise it has to be a hardware issue.
I finally found out that Snapchat was draining battery as hell. I deleted it, but still it's draining badly. What can I do? Are there some good power saving tweaks or something?
Thanks
It will suck but your going to have to go app/mod by app/mod youve installed to find the culprit.

After you install the app, you can try disabling the tweaks that you have installed for a day or two to see how the battery goes. If its still bad, take a look at the wakelocks that's causing the issue. Or you can go for a full wipe and set-up your device from scratch without tweaks to see how the battery fares.
Hi guys!
I desperately need some help from you experts. I have recently noticed my LG G3 has been draining more battery than it should, especially when idle (or at least, theoretically when idle).
Please take a look at the sequence of screenshots (have in mind the analysis was made overnight, when the phone was sitting idle on my bedside):
Screenshot 1: You can see app usage has been the biggest juice thief, and an abnormal drain (24%) for a (supposedly) idle period of 6 hours.
Screenshot 2: Kernel & Android system are the biggest villains, but only sums up to 45%.
Screenshot 3: Taking a deeper look at Kernel, it shows only 7 minutes of CPU usage.
Screenshot 4: A deeper look at Android system also shows a small usage, only a few seconds shy of 6 minutes.
Screenshot 5: On the chart, we can see there was an absurd drain (around 20%) from 1:30 am to 5 am, and then it got stabilized. Wifi was on the whole time, and you can see it shows the phone was (theoretically) dozed 95% of the time.
Sctreenshot 6: Even though the phone was dozed, we can clearly see it has severe CPU usage throughout the whole night, and no pattern could be distinguished between the hours were the battery got the severe drain and the hours after. Even though the CPU frequency was low between 1:30 and 5 (except for a couple of peaks), the utilization averaged 45%.
This is why I need some expert's help. I cannot understand what is draining my battery, what is keeping my phone's CPU util so high... can someone please shed a light on this for me?
Thanks in advance!!! :fingers-crossed: :good:
Hello there guys. Anyone could please take a look at this and try and help me out?

Well, it's hard to answer simply such a complicated problem. There are so many variables to consider, but I would say rule out a few things first.
First, if you have TWRP installed, backup your current ROM and do a complete factory reset. If the problem persists, then you know it's something built into your ROM causing it and I would suggest swapping out that ROM for another. If the problem is gone, you know it's something you installed or modified in the ROM and you can start to narrow that down.
Second, I would try out the app WakeBlock. It's still in development, but it allows you to see active wakelocks (Android programming object used to keep the CPU running even if dozed) and block them if you want to. But the app may be useful for just tracking down battery hogs that are activated at 2am in the morning
Hope that helps! Good luck! :fingers-crossed:

Hi there. Thanks for trying to help!
I don't have TWRP, as I use stock ROM (phone has MobileIron installed for work use, so I can't have it rooted).
I already have wakelock detector installed on the phone, but I don't how many wakelocks during a night should be considered as OK or not...

True, you would need root to flash TWRP to allow backups/restores. However once TWRP is flashed, you could just install a ROM that does not have root and do not root it. That should pass all of MobileIrons checks which are mostly package name-based. In short, root is not required to keep TWRP installed. Something to consider.

Well, in reality you don't need any wakelocks active. Especially if you are asleep or not going to use the device for a while. Wakelocks can be doing anything from downloading advertisements for apps, to syncing emails with servers. You could block them all in a certain time frame, but that may be overkill. I suggest just going through the list of wakelock package names before you goto bed or when you know drain is at it's heaviest. The package name may be different from the name of the app, but it should give you something to go on. Just uninstall the heavy drainers or disable them enough so they can not drain you so much.

I'm in pretty much the same boat. I lose like 14-20% overnight and I have no clue why. Factory reset and it still seems to be that bad. I also use GSam and have almost exactly the same stats in terms of Android System and Kernel usage, so that means it shouldn't be an app thing (unless you and I have the same apps installed lol). I'm really at a loss as to why there is so much crazy drain.

I understand I do not need, but I meant how many wouldn't be "harmful". But I'll keep an eye in a night where this thing happens and get back to you.

The same problem here. I lose 20% battery per night. Problem is only appearing on stock rom with stock recovery, I have installed Flumics and stock rom zip from TWRP - problem gone, but I need stock rom with stock recovery.
