[Tip] How to analyze you battery drain

Hello all,
Here is my 2 cents contribution to all the people that are wondering why their batteries are out in 10 hours!
I would like to share my tool, and maybe get help with my code if people are interested.
MARKET LINK: https://market.android.com/details?id=com.WazaBe.android.BatteryDrain

The goal of my application is to show the battery drain in percent per hour.
This unit if for me the most important, I don't care about the charge level of my nexus.
So my analysis lead to:
5-10 % lost per hour when normal use.
more than 20% when on Youtube
about 1% (even less) during the night with wifi off.

Does it work on other devices running gingerbread??
Thanks for the app anyways!!

Yes, should work on any device, this app is really basin in term of code.

I just updated the app and removed thhe stupid graphs to have something more easy to read:
https://market.android.com/details?id=com.WazaBe.android.BatteryDrain

Great idea! My suggestion would be to add an option to show how long it takes to lose 1% for each %battery.

Great app, but it doesn't seem to work with Force GPU Rendering On

Great idea, and here are my suggestions:
Feature to show summary
Something like this:
Start logging: [datetime]
Time now: [datetime]
Duration: [?d ?h ?m]
Average drain: 1% per X minutes.
Common phone settings:
* Brightness: ?%
* Airplane mode: ON
* WiFi: ON ?%
* 3G Data: ON ?%
* NFC: ON
* Sync: ON (5 accounts ... ) <--- if possible to check/stats
* etc.
----------------
When measuring WiFi/3G percentage, just check every 1% change whether it is OF or ON
The idea is to be able to make screenshot of this summary to compare with other user when discussing about battery drain.
You know, to make this tool as some kind of "standard" tool for battery drain measurement. That would be nice.

A lot of great suggestion, the main problem is to detect when wifi, 3G, Bluetooth, etc.. are ON during a lost of percent.. I will have to make a lot of approximations!
I will create a summary screen next week!

I'm using a GSM Galaxy Nexus that is running stock 4.0.2 thats unrooted and has a locked bootloader.
I downloaded the app from the market and initilly it didn't work with GPU Rendering. Since then, I believe you pushed an update? Now the UI is blue rather than white (a good choice) and now it does work with GPU Rendering on

Great start, love to see where this one goes.

DLed it. Will try it now..

As much as I hate to analyze my phone's behavior...
...I still understand that it is necessary to know what drains the battery.
So until we get better batteries in our phones, I applaud efforts like yours. TY.

Just to be clear, my app will never try to diagnose wich app is causing the drain, I don't want to make hasardous approximations...
My goal is to display the raw data in the most efficient way and to let the user make his own decisions and compare the drain with or without an app installed or some settings turned on off.
I will try to display only very accurate data only

Just a question...
Do you need a lot of explanation for the summary windows I just created?
I don't want to make a too complicated app and will now work on making the app nicer and more clear to understant, but I would like to know what id the most diffucult to understand from your side.
Thank a lot for your feedback.

I think those look good, just an easy way to see average drain. It would be quite cool if you could break it down with a couple of averages (kind of like you mentioned in your first post):
%drain during standby
%drain while in use
I like where your app is going so far. Keep up the good work!

+1 on this.

I will of course implement that feature.
But you have to remember that the standby/in use detection will be quite approximative.
I need two consecutive points with screen OFF to start counting standby.
As you may turn on your screen during the interval, I don't like that for my computations... I can add some trigger, but I want my app to be nearly invisible regarding battery...
By the way, please wait one week or 2 and you will have something!

I'm quite good with the standby/in use detection being approximated. I'm primarily interested in seeing a value indicating battery drain in standby for long periods of time (like overnight) versus during the day while I am frequently using the device.
Definitely looking forward to what you can cook up!

Most likely, it's an app misbehaving.

Try using something like juicedefender lite or go power manager from the play store. They can help you set up different modes that toggle things that eat battery life. They also tell you what apps/hardware is using the most battery.
I found that on mine, the screen was using a ton as was the 4g at work (bad connection). So Juice defender will turn off/on my 4g every 15 minutes and download updates without draining my whole battery. Good luck!

The thing is I use the task manager a lot closing my apps and all. But it has not improved my battery life at all. And its frustrating since I'm out of the house almost the whole day (9 to 10 hrs sometimes 12 hrs). Should I change my kernel or something?

stop using a task manager. that is probably what is killing your battery.

Add this tweak to /system/build.prop
ro.ril.disable.power.collapse=0 - This setting puts your phone into a deeper sleep when on standby. This may improve battery life.
pm.sleep_mode=1 - This sets the phone to use power collapse when in standby.
0 - Power Collapse Suspend
1 - Power Collapse
2 - Apps Sleep
3 - Slow Clock and Wait for Interrupt (default)
4 - Wait for Interrupt

there are many reasons that are responsible for fast battery drain.
1. App using the Processor to its fullest.
2. App misbehaving (restarting multiple times in background)
3. Overheating of device due to any external or internal factor
4. Battery fault.
I would recommend you
1. Set the brightness of your phone to "AutoMode"
2. Use Power saving mode while not playing resource hungry games.
3. Download Clean master. that will solve the app misbehaving problem which results in Overheating.
4. Charge your phone wisely.

[APP] 'Data Lock' : unplug 3G while the screen is off

Hi
I'm not a developper but I created an app with the Tasker App Factory that unplug 3G one minute after you lock your screen. The one minute delay is here to prevent the phone plugging and unplugging at any time the screen goes off. During this delay, if you wake your device, the process will stop and begin again when you turn the screen off. When the screen is off, after the 1 minute delay, 3G is stopped while the phone is in your pocket to prevent battery drain
Once it is stopped, if you wake the device a new 5 second delay is started, for those who just want to check the clock , and then the 3G is plugged with a ''Data restarted'' toast
Note : Tasker IS NOT required to use this apk :victory:
Feel free to request any modification like the delay or the toast text, I'm here to share such things. And if it helped, don't forget the :good: button

cpu usage
Your app gave me a watchdog alert as it's using more than 50% CPU. This would counteract any benefits as eating CPU results in battery drain.
It also uses 15.3 mb of ram when its role is simple and in no way justifies the ram/CPU usage.

Going to try this as I am tired of manually switching to 2g all the time.

It seems to be using more juice than saving it.
Shows up as 2nd highest draining source after screen.

You seem to be right... That's too bad because I use tasker 24 hours a day with many profiles and tasks and it saves my battery!

very good.
i make a few sugestions
1. hide icon (dont need show icon, dont have config to make)
2. create widget or icon in notification to enable or disable
3. put in google play for updates
4. thats be good work in wifi too. or switch this option...

Someone Kill My Wakelocks!

Well the answers simple. Uninstall Battery Guru.
In my experience it doesn't really do anything.

I had the same issue and once I uninstalled Battery Guru it was fine.

I'm just reporting what I see. It's up to you to decide what you actually end up doing.

You have Beautiful Widgets too, maybe you could use that instead for weather. There are a lot of skins for the widget. Also Lux seems to be waking up your phone a lot, perhaps you could get rid of that too.

But Lux is a battery saver isn't it? It periodically adjusts the brightness levels (it's not like auto-brightness)

Turn auto brightness off and set you screen brightness to the lowest possible you can tolerate. Any app that is running is a battery consuming app. Also BBS should be frozen if your not using it to diagnose an issue the least you have running the better off you are.

I had really bad battery performance when I was using Lux. It does seem to adjust brightness levels in an adequate way, but if I recall correctly, I was getting a lot of wakelocks when I had it. So while it probably was saving battery due to better screen usage, it was killing me in the deep sleep department.
Just my experience with it.

I will do that then for sure.

I could suggest Greenify for your installed apps (not system apps). But with the alarms it looks like you set alarms in your stock clock and on your 3rd party clock which is what could cause some wake locks

So I keep getting these wake locks when my phone should be in deep sleep. Caused my phone to drop 25% over night with no activity. I've done research on it but most of it says that this app is for your apps that sync. I've checked my syncs and everything seems Ok. Is there anyone that can shed a little more light on the subject?

Verizon took out Battery Saver, here's Qualcomm's solution: Snapdragon™ BatteryGuru

I, and a few other users have noticed that Verizon decided to have HTC strip out their battery saver toggle on the Sense ROM (4.2.2) that ships on VZW's One.
Luckily, Qualcomm provides a standalone application which covers 90% of what the toggle does.
Snapdragon™ BatteryGuru
https://play.google.com/store/apps/developer?id=Xiam+Technologies+Limited,+a+Qualcomm+company
(personally, I haven't found the need to use it yet, but I figured it would help some people)

Thanks man, I was looking for that battery saver mode everywhere, but I guess this will do as well.

Thanks for this info. Anyone know if this is particular app will perform better from more generic battery extenders like Juice Defender?

According to the reviews all it does schedule syncing. Don't know how that is going to save battery...

Battery saver apps are a joke. The only thing I liked about power saver mode was that it cut the CPU frequency down and cut data off after a certain period of time. Other than that, if you need to save more just turn your brightness down, turn off bluetooth, use WiFi as much as possible, and use the phone less.

Think about how often you "actually" need to have your emails and set it to that. For me, my Yahoo emails I don't need it to check but once hourly. But Gmail is push automatically so I won't mess with that. My corporate email defaulted to push but I often don't need it to constantly update and annoy me so I'm contemplating on 30 min intervals. Setting your emails to longer intervals should reduce that "email stress" that most people seem to endure these days.

The app has low power mode controls.
You can turn off mobile data during inactivity.
Some other features.
It basically gives you battery saver control on any Snapdragon based device.

Lol you could always just use BoneStock ROM. Andy threw the battery saver apk from (can't remember dev's handle. sorry) back in it.

It limits CPU, dims display and disables vibration feedback. Basically everything you can do yourself in stock and if you have a CPU app like SetCPU. Just a one click option that Verizon took out bc they hate battery life I guess idk.

Im running bonestock now, and the power saver has increased my battery life fairly significantly, i'll take that, because at first i wasnt impressed with the battery life, and i watched the ifixit tutorial on how to tear this phone apart to replace a battery, and i want nothing to do with that
