Diagnose by Battery Doctor of OPG Pro

17th October, 2014 · fonter · Leave a comment

Yesterday, When I was ready to develop OPG Pro with i9100, Battery life is full, but suddenly found this phone was turned off. I wonder what happened? Let us see this classic battery case.

1. First, Check Battery option in system settings, the red square shows battery life instantly dropped down, Both Youku and cell standby consume 96% of battery life. However, it is difficult to see from them, and may be it made a mistake to misdiagnose as cell standby


2. Secondly, let us into OPG Pro of Battery Doctor, From the chart, It is more intuitive to show battery life instantly dropped down, Such as the electrocardiogram


3. Let’s look at the reasons of power consumption, what events happened? from 60% to 31%, there are two important events, a wakelock and screen wakeup, this wakelock wake up system so that Android system can not sleep. +screen mean that screen awaked and turned on suddenly.


4. Then, Find out which applications have wakelock permissions? the figure only two applications.


5. Switch statistics to the last charge or statistics to the last unplugged, kernel wakelocks or Partial wakelocks, To find out the main wakelock. the longest realtime of “mywakelock” is 21 hours 48 minutes, it is the reason.


6. Although it is known mywakelock led to drain, let us return to the first pic, the power consumption of Youku reached 6%, Is Youku creates mywakelock? At this point, Decompile Youku apk to see this wakelock.

Finally, We are planning to develop an app to control wakelocks.  Dowload OPG Pro App

Cloud Battery Stats

26th March, 2014 · fonter · Leave a comment

Now we provide a new service for you.  We are working hard to develop Cloud Battery Stats.  it predicts power consumption of each device and app by big data.  big data means more people use OPG or OPG Pro and it is more accurate.

  • Top screen power consumption
  • Top third-party apps power consumption
  • Top wifi power consumption
  • Top kernel power consumption
  • Top mobile radio power consumption
  • Top phone idle power consumption

Here is screenshot.

Android Entropy of OPG Pro

16th January, 2014 · fonter · Leave a comment

I did a bit of digging and testing about Android entropy and discover a nice trick to have a nice fat Android entropy, Android entropy is able to improve battery life when using and reduce lag.

If an Android entropy pool isn’t full, applications need entropy “just ‘hang” and wait for more to be created. That’s apparently what OPG Pro is designed to avoid.

kernel.random.read_wakeup_threshold contains the number of bits of entropy required for waking up processes that sleep waiting for entropy from /dev/random.

kernel.random.write_wakeup_threshold contains the number of bits of entropy below which we wake up processes that do a select() or poll() for write access to /dev/random.

Normally, read_wakeup_threshold is 64 and write_wakeup_threshold is 128

This page is about kernel random at linuxinsight

you can use sysctl to set good values and low and behold.

busybox sysctl -e -w kernel.random.read_wakeup_threshold=128;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=256;

In one command prompt you can watch the entropy_avail with this one liner:

while :; do cat /proc/sys/kernel/random/entropy_avail; sleep 1;done

In a second command prompt you can do the sysctl thing…

we can find that write_wakeup_threshold doesn’t effect entropy_avail at all.

But read_wakeup_threshold is a totally different

Try:

busybox sysctl -w kernel.random.read_wakeup_threshold=2048

The entropy_avail just started climbing….

All the way up to 3600+ and just stayed there. Never went down at all.
Actually, the more I did stuff with the phone, the faster the level would climb.

we played with different values.
Setting it to 1000… entropy would go up to 3000 and then drop to 2000 and up to 3000 again….
Setting to 750…. entropy would go up to 2250 and drop to 1500 and up to 2250 again…

So the pattern is:
max entropy_avail=read_wakeup_threshold * 3
min. entropy_avail=read_wakeup_threshold * 2 (ie. read_wakeup_threshold * 3 – read_wakeup_threshold)

after testing, we found that it is better, but we don’t know it run the same well on all devices.

busybox sysctl -e -w kernel.random.read_wakeup_threshold=1366;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=2048;

Maybe somebody would like to give it a try and test to see if it actually saves battery by setting read_wakeup_threshold to 1366.

OPG Pro have four profile, there are default,light,moderate,aggressive.

Entropy android

Default – Standby better than using in this setting

read_wakeup_threshold=128
write_wakeup_threshold=256

Light – It is similar with Moderate, just lower value.

read_wakeup_threshold=1195
write_wakeup_threshold=2048

Moderate – Using better than Standby in this setting.

read_wakeup_threshold=1366
write_wakeup_threshold=2048

Aggressive It is similar with Moderate, just higher value.

read_wakeup_threshold=1708
write_wakeup_threshold=2048

You can see these video.
