I have been using both GSAM<\/a> and 3C Battery Monitor<\/a> for many years on Android<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Both are GREAT apps in helping you finding out what is going on and especially what eats your device’s battery.<\/p>\n

There is a bit confusion [*] on the naming on the 3C one, as it offered as a stand alone<\/p>\n

“3C Battery Monitor<\/strong>“<\/p>\n

but also as a part of a larger toolbox with some extra goodies with a slightly different name<\/p>\n

“Battery Manager” as a part of the larger “3C Toolbox<\/strong><\/a>“<\/p>\n

This Toolbox not the least also contains the “Process Monitor”\/”Task Manager”.<\/p>\n

And until a few hours ago I thought that 3C could not do quite what GSAM could without root. I was wrong….<\/p>\n

 <\/p>\n

If you find this<\/a> or this<\/a> post on the 3c site, you will see that executing the following command does wonders (on adb<\/strong> see also this<\/a>)<\/p>\n

adb -d shell pm grant ccc71.at android.permission.BATTERY_STATS<\/b><\/i><\/p>\n

GSAM already suggest their users to do the similar for their app on install<\/p>\n

adb -d shell pm grant com.gsamlabs.bbm.pro android.permission.BATTERY_STATS<\/strong><\/em><\/p>\n

But did not know that the similar worked for the 3C Battery Monitor too!<\/p>\n

If you are using the ‘free’ versions, the similar commands are<\/span><\/p>\n

adb -d shell pm grant ccc71.at.free android.permission.BATTERY_STATS<\/b><\/i><\/span><\/p>\n

adb -d shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS<\/strong><\/em><\/span><\/p>\n

Now the Battery info I get from 3c Battery Manager\/Monitor are (click to enlarge)<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

And this is reasonable similar to what I get from GSAM<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

Both offer even more detailed info on a specific entry:<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

(the package name is scrolling on the 3C if it is too long )<\/p>\n

 <\/p>\n

3C Battery Monitor is generally more lean on the battery than GSAM, but none of them are heavy on it. That they appear as prominent users above is due to me playing with the 3C Toolbox a lot, and would not be so in normal usage. See e.g. this<\/a> from my BB Priv where 3C had used 0.1% and GSAM 1.0% of the capacity over an almost eight day period<\/a>.<\/p>\n

 <\/p>\n

Note that in 3C “On Battery<\/em>” is the total since FULLY charged in contrast to “Since charged<\/em>” that means “Since LAST charge<\/em>“. Rather confusing IMHO.
\nSimilar on GSAM “Since last unplugged” is (of course) not only physically plugged, but goes for wireless charge as well.<\/p>\n

I’m not sure how either of them includes or excludes what happened during<\/em> any intermediate partial charges. This could make a huge difference if e.g. used with a slow 500mA car charger while doing sat-nav with the display on, as it might be using about as much as the charger can provide, and thus not reach the fully charged state.<\/p>\n

(I would strongly discourage anyone from using a device this way in normal usage, as heavy usage means heat, and heat during charging or discharging is bad for the overall battery life, so better to charge the phone fully before you go, so the battery is inactive while the device is being powered by the car charger for doing the heavy job, see also this<\/a>)<\/p>\n

 <\/p>\n

Both display the total usage in the period. Do not get confused if you see a number over 100%, if you have requested since last full charge<\/em>, and the device have been partially charged in the mean time. As it is the sum of the usage in each period between the charges.<\/p>\n

In GSAM they also display a mean usage rate. This can be quite handy as a measure of how lean&hard the device has been used.<\/p>\n

 <\/p>\n

They are not quite agreeing on the percentage blamed on the display. In the above 3c Says 17.94%<\/strong> and GSAM 48% of 25% or 12%<\/strong>. I do not know how to interpret this difference.<\/p>\n

 <\/p>\n

I like the many graphs and options on 3C the most. And the developer has a very high service level!<\/p>\n

On the other hand GSAM is a little simpler to use and offers detailed info on the quality of the cellular signal in the period. Quite useful to find a good place\/orientation to put your phone overnight.<\/p>\n
