CPU usage percentage question - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

After clearing junk and caches, what would be an acceptable usage percentage? After cleaning mine is at 44%

Thanks, I do that too
Also been using Samsung's "Vitamins" app.
It has cache and CPU cleaner, plus a notification of any new software updates. The updates may be useless but it's there none the less

Possible simple fix to Multitasking and battery life help - worked a charm on my D3

This may be of great use - it was to me on my Droid 3 and I noticed weird settings posted on here in HTC's default Build.prop that explain IMO the memory Issues people are perceiving.
Multitasking can easily be fixed in build prop by editing the corresponding values (I assume, not tried it yet but I've seen the values in the prop.). Some of the default HTC settings baffle me. Or use RomToolbox by JRummy - its easy and works on Boot. You can also edit lowmemorykiller using this app, I always start on mild and take off about 6 megabytes on the bottom 3 categories.
Ive not rooted yet but on my D3 (512mb ram) I used dirty ratio 70% (HOX default is 0%....!) Dirty background 90% (Hox default is 30%) and vfs cache pressure 10. Hox default is 100. This makes android flush the cache less often, saving battery and eliminating stutter (uses CPU time and I/O to flush the cache), keeps apps in background ram leaving you where you left off and doesn't negatively impact on battery life or degrade performance over time (reboots every couple of days can't harm though). I've no idea why the HOX's default settings are so aggressive - unless they thought users might get an errant app, leave it running and complain when they dont know why the battery is draining... oh and kill OOM allocating task was also a yes (can't remember if you set that to 1 or true in build.prop but there's a checkbox on Romtoolbox for it).
On my Droid 3 with the above settings, I could infinitely multitask (VM Heap of 48mb - but on HOX you could easily double that for more tabs in browser etc) and my battery gained a perceived time of about an hour at least - maybe more, due to the apps always remaining open and CPU time not having to be used reopening them and redrawing the past state they were in because theyve been pushed out of RAM.
I researched the above for ages looking for and testing the best combinations online when I had my D3 (even with 512mb ram Moto's settings were way less aggressive than HTC's are at default) and made sure they wouldn't cause lag over time, or loss of performance over time - as well as providing optimal battery life.

[Q] Blinkfeed high battery usage even after removing the widget

Blinkfeed has high battery usage on my Android HTC One M8. Not necessarily high _cpu_ usage, from what I see in SystemPanel (3rd party app), but Blinkfeed consistently accounts for between 15-30% battery usage in battery stats. The gap between its battery usage and any other app's batteryusage is huge. It's like 27% versus between 3-5% for all other apps. Blinkfeed appears to be non-removable. I'd like to know if there's a way to disable or cut down the battery usage without using a custom rom. I had CM on both of my previous HTC devices but I'm not quite ready for it on my M8 yet.
I am also confused about how its extremely low cpu usage between 0-1% (from what I see in SystemPanel) correlates to its high battery usage in battery stats. Average consumption is 0.2%. The process name is com.htc.launcher. Could a different launcher help?

That still seems very high IF the system panel stats are correct, I think Blinkfeed is what the default HTC launcher is named, as I also noticed it still showing after disabling the widget. Have you tried another battery stats app like GSam? How is your battery life overall?

My battery life is pretty awful if I don't enable power saving mode.
I will try a different battery stats app, as well as a different launcher, just to have some data for comparison. Thanks!

Definitely worth experimenting to see what's what. I can't complain about my battery life, but I may well have different usage patterns, apps installed etc, so can't really compare. Generally though I get over a day on a single charge with around 4-4.5 hours screen on time.
Try nova launcher and freeze blinkfeed. It's a non issue for me. ?
Thanks for the tip on GSam. I've found that GSam and the stock Power app have vastly different ideas on how much battery usage Blinkfeed is responsible for. GSam has it pretty low, like 0.4% versus the 17% in the stock Power app.
I've started using the Google Now launcher, which is pretty cool, but I'll definitely give Nova a shot.
Thanks again!
Maybe you should try ge Rom without bf?

Improving battery longevity

I've had Lollipop since the intro and and at first it was fine then it started to be buggy. I decided to hard reset and the phone works better but what I miss was the stellar battery longevity. From an unplug at 7 am I'd have 45-50% by 7 pm, now that's gone. I have 13% by &pm. Keep in in mind that I have a retail version and turned off any app possible that I don't want to work ,plus used Debloater. Lastly I use Greenify .
Looking at the battery specs I see that the Exchange services are at the top . Plus I see that Nova launcher is high on therunning list. This is a new version and i wonder if it's a power eater?
Here's what's in the running list-
settings- 210mb
nova- 71mb
weather app- 24mb
ipec - 8.3mb
securitymanagerservice- 5.4mb
passpoint settings- 4.4mb
android- 5.4mb
Bluetooth- 9.7 mb, Bluetooth is off and used only when i need it but still shows in this list
google play- 52mb
contacts- 15mb
context service- 17mb
email- 43mb
exchange- 20mb
greenify- 8.8mb
samsung keyboard- 45mb, why does the keyboard have to show and it's not being used
systemui- 16mb
Thanks in advance

Well, I'm not sure why you're using the data you've provided to try to explain battery usage. The data you've provided looks like the amount of RAM the app/file occupies. The amount of RAM an app or process uses is not indicative of the amount of battery that will be consumed when that app/process is running. A much better indication of what's going on with battery consumption is data that indicates what and how much battery is being used by an app or process...like screen on time or cpu time used by an app.
If I understand you rightI think you're talking about the settings /battery area-
if so
Exchange services are at 4%
Android system- 1%
Android OS- 1%
Email- 1%

Yeah, that area gives you a better idea of what is using the battery. If you really want to analyze what is using the battery resources in your phone you need to download and run an app that is designed to monitor your system and report what is using battery resources, how much and when. There are a number of apps in the Play Store that will do that. Many of them are free, but the better ones will cost you a dollar or two. But, if you're really interested in finding out what is "eating" your battery resources it may be well worth a dollar or two.
Here's list of the most common battery hogs: Facebook, live wallpaper, apps that sync data or other information every minute or two, screen on time-how often are you looking at the display and for how long, streaming video and music, gps, wifi, nfc and bluetooth turned on but not needed or in use, widgets open and running but not needed or used.

Facebook, I use a browser link not the app
no Live wallpaper
apps that sync data or other information every minute or two- sounds like the emails. There doesn't seem to be a tweak anywhere for that
no streaming or music
GPS is on but didn't seem to bother before the reset
Wifi - used on demand
NFC- don't use
Bluetooth-also used on demand but is still listed as running when off
The only widget i use is my weather app- I do like it though- Weather XL
Thanks

Is the cleaning app really necessary? [S9]

Under the Device Maintenance section there is the "storage" optimization option. Since when is cleaning cache often a good thing? Apps build cache to function snappier.
I also tend to believe that building cache consumes more battery since it's an operation as well.
Sometimes if there was an app that couldn't update or install due to space issues, cleaning the cache would allow it to install due to freed space.

Hey there. I honestly wouldn't even bother about the device maintenance section. Cache is important because the app will perform faster because the cache is saved data. The cache may not necessarily increase the opening time or overall app performance. You should only consider clearing the cache if it takes a lot of space. Also, the entire freeing up ram thing is a gimmick because they are system services or vital app services that it closes and it will actually consume more battery because the background processes restart. Greenify is a good alternative or to truly stop an app's background processes you either need root or you need to disable or uninstall the app(depends on whether it is an installed app or a system app).

Applications Background Services

I'm tired of background applications that starts bypassing permissions allowed on xiaomi assembled android device that drains battery rapidly.
Tried many ram booster, task killer, battery optimiser and relevant applications however couldn't experience any difference as attached screenshot along.
Looking for suggestions to fix it once for all.
