[Q] Working for better battery life

Hi all,
I've been working on getting my XT862 to give me more life on the battery. I've rooted and debloated using psousa's stuff, but I'm still not where I'd like to be. I've noticed a few interesting things:
AOS is showing as the top user in the battery monitor. Currently it's at 32% with my display and WiFi bringing up the rear.
Even though I've run the debloat script as root and confirmed the rename of skype.bourbon and motoprint, these things still start up. How is this possible?
BetterBatteryStats shows that the suspend process is my main battery user. How does one fix that?
Any advice on what to look for?

best route is to install a custom ROM and try different ones out for battery life. I would suggest Maverick ROM also make sure you wipe battery stats after installing a new ROM and fully cycle your battery.

I'm guessing suspend is another way of saying System Idle.. if you wanted to get rid of that, make a nandroid backup of your system (via bootstrap or safestrap) and experiment what system apps/services you can freeze (via Titanium Backup) without getting force closes on the stuff that you use. I have about 30-60 system apps/services frozen depending on the ROM that I run. I have no force close issues, and my system idle uses about 1 percent of the battery per hour.

Additionaly, if you are using the CDMA network, force CDMA mode, likewise from GSM/UMTS, if you are using it, force it, do not use Global, as it will have both radios running and searching for service.
Disable the use of wifi when you aren't using it (there is an option to auto turn it off when the screen turns off, however this may cause worse battery life if you are using data as it will try use your mobile network, requiring more power), if you wish to leave it on, increase the scan time interval (i made mine 10 mins, up from the stock 45 seconds)
Auto brightness (it isn't really that bad...)

And get the app called juice defender. Once you set it up it controls all of your wireless stuff. Like turning wifi and 3g off when you turn your screen off, etc.

If you use Wifi often, it is a good idea to check your Wifi Sleep Policy. To do this, navigate to:
Settings > Wireless & Networks > Wifi Settings > Advanced Settings (hit menu to access this) > Wifi Sleep Policy
I have mine set to 'Never'. By default, it was set to turn off the wifi when the screen went off, so any background apps that run and use data default back to the mobile connection. When you turn the phone back on, it turns the Wifi back on from sleep mode. By changing the sleep policy to 'never' you prevent this disconnect/reconnect to Wifi cycle.
This helped my battery life when connected to Wifi. Let me know if it works for you.

Thanks to all
Thank you for your replies everyone. I'll have to get TB and start freezing stuff. What confuses me though is how a service like Verizon Apps or Skype Mobile gets started even though it was renamed ".bak" by psousa's script. Also, I've noticed that when I run the restore bloat software, I don't get back all the apps in my app drawer. I'm not sure why that is.
Is it possible something got screwed up if I ran the debloat script twice? I see that it does a bunch of mv proggie.apk proggie.apk.bak type work. If the first file wasn't found, is it possible that it overwrote the .bak with gibberish?
My WiFi sleep policy is never because I have WiFi all day and I like Google Talk a lot. I'd be happy if I could get WiFi/Display as my top users, just AOS seems like a bug.
I'm on UTMS so it's forced to that all the time.
Maybe the answer is to try the mods. Or maybe SBF to the stock and try again?

Did you saved changes when you changed the wifi to be off when screen is off?

Yes i saved the settings
I tried this on Kk2 and LA4
And same result not working

same for me with Cassie's Xtra lite and Franco kernel V5. Then as advised, i use now green power to switch off/on automatically wifi and datas connexions.. better than nothing.

I use Llama to do this. It does exactly what I want, shuts down WiFi 1 minute after I turn the screen off unless charging on mains, turns it back on on open, but only if I am at home or work.
That gives me everything I want (I have some apps that only sync when charging to save battery).

Deep sleep problem

Hello world,
I just noticed this disturbing issue. I lost about 16% battery in one night. When I looked at battery state I noticed alot of tiny little wake moments during the night.
What kind of application can cause this? Or are there any known bugged apps that cause this?
Wakker is dutch for Wake

. THE Galaxy Notes when goes into standby (screen off) should go into deep sleep mode is a mode that allows you to keep to a minimum processor frequency to conserve the battery. Unfortunately, between the various firmware updates that we do and the various programs that we install (some of these work in backround without noticing it) can happen that the Note is no longer able to enter deep sleep mode remains fixed at 200mhz even while on table with display off.
To find out if our notes go into deep sleep, just install the free CPU Spy download here: https://play.google.com/store/apps/...wsMSwyLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ..--- If your notes do not enter into deep sleep the greater the percentage occupied by the item above, or 200mhz. The fact that it is a 200mhz is quite useless to us since we're not doing anything with the device as it should be on standby at that time. It happens so that at night, leaving the device on but without the latter is used, however, so battery consumption (having remained fixed at 200mhz) and the following morning surprise that we find the percentage of low power.
To overcome this problem needs to be done in the following way: Deep Sleep Guide
- Go into settings and remove the following tones: sound freezes the screen and sound selection - Set the device in flight mode - Turn off the device - Remove the battery for 10 seconds - Power on the device - Wait until everything is loaded - Remove Airplane mode
And that's it. The Notes should regularly go into deep sleep after doing this guide. To check everything just to keep notes on standby for about ten minutes and see if The candidates and the percentage of deep sleep increases.

Hi
Even I face this battery issue....it is severe in my case. I hardly get 14 HRS of battery life even after about 30 charging cycles
I've installed CPU spy, I found that the CPU stays in 200Mhz, for testing purpose I had kept my cell phone untouched in flight mode for about 12hrs but still I lost more 50% of battery.
I had tested the battery by completely charging it, it just drains before my eyes . . .
I don't know if this is deep sleep issue. please help me.

1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others. 2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html 3. Set Brightness to low value, disable autobrightness 4. Disable or scale down vibration and haptic feedback 5. Automatic syncing of your accounts is battery consuming. Sync manually if you can 6. Set screen timeout to 15 seconds 7. Disable fast dormancy (dial *#9900# and do it from there) 8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state 9. Disable location services via wireless networks - are you travelling that fast that you need those? 10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

Download BetterBatteryStats and look for wakelocks (partial and kernel). Google them if you don't know what they do. Then uninstall them or fix them somehow.

Am happy to say that the deep sleep issue haS been resolved.
I downloaded better battery stats, found that the process l2_hsic was stopping my phone from going to deep sleep mode. I tweaked the wifi settings and the battery life increased exponentially.
Thanks better battery stats

What do you mean "tweaked the wifi settings"?

My galaxy note 2 battery is draining fast and the "android os" is at about 65% at end of day and now my battery last about 10 hours. I was trying to follow your instructions above but got lost trying to find the settings to remove some tones you mentioned. Which tones are you speaking of.
Thanks...

Note 2? Wrong forum..However, to answer your question, he is talking about the tones under Settings> Sound> System.

Permanent Battery Saver On

Is there a way to permanently switch on the Battery Saver option instead of it automatically switching on at 15% battery and being disabled when charging?

Go to settings, battery, menu, and switch on battery saver with slide switch.

Well, i need it to be on permanently. ^What you suggested doesn't even allow a toggle when the phone is connected to a charger.
BTW this is for the latest lollipop OS.

I have Android 5,0,2 there is no way to have the phone on battery save when its charging (why would you do that anyway) Android turns it off. When you stop charging you turn it back on. I wouldn't know what else to suggest. If you have problems with battery see this thread.

Ways to improve battery life?

Sorry for the long list of screenshots above, and also for creating a new topic, but didn't want to spam the normal board for battery discussion.
Anyway, I have the N920I model of the Note 5, using it on Telkomsel in Indonesia, and getting average 3+ hours SOT on this device, which I think could stand to be much better, given I got around the same figure on the Moto X 2014, which has significantly worse battery life according to most counts.
Here's my settings:
Screen brightness 60%, auto
Sync on
NFC off
Location high accuracy
Bluetooth on from 8 to 3.30, then off for the rest of the day
Connected to an Asus ZenWatch 2
Wi-Fi on from 4 to night, from plug out in morning to 8
Here's the list of apps I disabled:
And here's how my usage goes:
* Plug in when I wake up, then out at 7-ish.
* Get to school and let My Places switch to "Work" mode, where it changes the Bluetooth, Wi-Fi and power saving settings and turn off data before starting the first class.
* Turn it on between classes to check for new messages.
* Leave at 3-ish, and get home, letting My Places change the settings back to normal. At this point, the phone is usually at 70% with an hour of screen on time to report.
* Use it periodically throughout the rest of the day, switching between WhatsApp, Snapchat, Netflix, Chrome and YouTube.
* Plug in at 8 or 9, then plug out before I go to bed, topping up what's left in the morning.
It's a fairly light usage pattern, which reinforces the point that this phone should get more than just 3 hours. Any specific app you're seeing here that might be putting its toll on battery life, or a specific setting that you can advise enabling or disabling?

Just try counting how many threads there are about battery life in this section. A lot! I, being one of the victims of horrendous drains, have tried everything. If you keep the device relatively clean(software) and it still drains then there is only one thing you can do. Wait for the marshmallow. I'm sorry but that's what it means owning a samsung device.

try gsam battery monitor. It may give insight into what is going on....

Already did! But Android OS is always the top consumer.

thanks!

As Octa_core mentioned, there are quite a few threads about battery life already. They might be of benefit if you haven't already looked through them.
Here are a few things you might try, if you haven't already.
- Turn off location high accuracy, or only turn on location when you need it (if you can)
- Turn off location history
- Turn off Always Allow Scanning in Wifi advanced settings
- Turn off S-Pen settings (alerts, sound, vibration, detection)
- If using Google Fit, disable activity detection in settings (this definitely helped my idle drain)
- Turn off anything you don't need to sync on your Google Account
- Disable enhanced LTE services
- Turn off Motions and Gestures you don't use
- Set touch key light duration to Always Off (under Display)
- Turn off Smart Stay
- Set Screen Mode to Basic
- Use a darker theme
- Try disabling some apps, especially S-Finder (may require Package Disable Pro to disable some apps)
- What does your signal look like in GSam? Some drain may be due to poor signal.
If none of that helps, then uninstall or disable (probably will need Package Disable Pro to disable) all apps you installed, and I also recommend that you disable S-Finder. Turn off all radios (location, NFC, bluetooth, wifi, even data) other than cell. Reboot after those changes. Monitor and see how idle battery drain is. After I did this, my idle drain was around 0.4% per hour. Then you can gradually enable radios/apps, only 2-3 at a time, reboot, and see how it impacts idle drain. Continue until you find app/radio that increase idle drain.
