Hi,
I'm noticing that my android os is one of the main reasons my battery is draining.
I mesured this;
8u40: 23min cpu time
9u23: 29min cpu time
9u41: 32min cpu time
I haven't used the phone in the meanwhile. I get an 18 hours out of my battery, which is not suffient.
I lookt at drainer apps and such, but no one offers a solution for my problem. I need an app that logs the cpu usage, so I can detect what is consuming my cpu, thus my battery.
I have android 2.3.7, model MT27i, Kernel version 2.6.35.7+, build number 6.0.B.1.564

is there a program that lowers cpu usage?
so the battery can last longer?
yeah there are programs to underclock the phones
which one you should use depend on the cpu in the phone
How do these interact. Do you get better battery life by using these apps. Or do they just work when you are running a stock rom??
I still use juice defender to turn off my data when the screen is off. And battery defender during my sleeping hours if I ever forget to charge my phone.
Battery opt apps usually prevent apps from using data, which in return doesn't drain the battery as much.
Custom roms usually try to govern the CPU frequency. For example lowering it to 1ghz instead of 1.5ghz. They can also change the voltage of the processor.
Basically custom roms and kernels will signifiatly change battery drainage due to processor changes.
Battery optimization apps can generally improve your battery usage depending on the apps installed on your device.
After reading a lot of battery drain threads on this Samsung Galaxy I9003 subforum i have a doubt:
The recommended solution is to install a clean android 2.3.4 rom?
In my case the phone came with froyo and after a couple of months i decide to upgrade up to 2.3.5... anyway, about one week the phone starts to constantly heat up on stand by mode without 3g or wifi activated and off course the battery starts to drain :S on battery stats i can see the bigger consume (about 62%) is related to stand by mode :S
I try :
battery calibration
factory reset
wipe
reflash 2.3.5
flash 2.3.6
But sadly the problem persist :S
Todayi installed CPU spy and i got a big surprise when i saw the stats of CPU speed, most of the time turns to 1000mhz , like i said the phone it's ond stand by mode with no 3g, wifi connections activated :S
Also i rooted the phone and installed setCPU to limit the max speed up to 300mhz, with that i can see the phone doesnt heat that much (compared when it runs at constantly 1000mhz) but still works at constant 300mhz whatever i do...
I really hope that the solution is to reflash 2.3.4 (or maybe lower?) firmware
Thanks for share all your knowledge and help people like me
If that the case then its an APP. You surely have an app that avoids your phone to go to sleep.
Thanks for your attention and time, i hav running setCPU (at barely 300mhz) and now the CPU temp is always at 32°C also i installed Watchdog lite and doesnt show any program doing an excesive CPU usage :S
Really i have no more ideas of what to look at
Yesterday at night i was reading a lot of drain battery related post (all the threads i found basically) and do the following:
Enter to CWM recovery menu > Advanced > Wipe dalvik
Also i select the ondemand settings for setCPU
Now the phone it's all the time on stable 36°C but sadly my battery still is drained (probably on deep sleep) Most of the time the processor is only at 300mhz and looking the battery stats android system and screen use an average precent (42% for display 23% for android system)
From a full charge (over a powered off phone) after 4 hours the battery has only 40% of ramaining charge and the phone it's on deep sleep (this phone today it's used only for make and receive calls, so no internet connection is activated)
No other people are facing this issue?
Hello,
just installed CPU-Z from the app store which shows a constant 30-40% CPU usage. killed all tasks with task manager, but still doesn't change.
Is this normal or anyone else experiencing it?
Running Stock HTC Android 4.0.4
Cheers
Mine is running at about 10-30 %.
One S (S4), Stock rom 4.1.1 (Lastest)
Do you have any problems with your phone?
Something to think about: your CPU will adjust its frequency depending on the load for energy management. For example: if your doing nothing you could be running at single-core 128MHz. So maybe it shows 30%, but it could very well be 30% of 128MHz(in short).
So those percentages do not necessary mean your phone has a problem.
My battery life is aweful. I can get around 2-2,5 hours of screen on time during a day...battery seems okay though. might have to do a factory reset or flash some custom rom.
Hi,
I've a stock Nexus 5 on 6.0.1 (M4B30X) that, according to GSam Battery Monitor, has consistently high CPU usage (20-40%) and CPU even when idling overnight. Is this normal? I was expecting it to be close to 0% when idling. How do I figure out what's causing the CPU utilization?
