Hello,

GSam did not show up anywhere, I can only tell what I noticed. If this is not credible enough for some people, it's fine, but in this case, I want to report about optimization, not seeking for help. :)

I couldn't provide screenshots yet because I had to analyze the problem a bit closer, so I took screenshots of my battery life graph when GSam was installed,

and a screenshot after fully charging it and let it sit for a while without GSam.

And I can tell it was a pretty terrible time knowing I can't use my phone because I'm investigating :)

This is what I've discovered:

First, the screenshots of my battery graph when GSam was installed:

As you can see here, the time I switched on airplane mode was when I went to sleep. The standby battery life time war pretty terrible, since it lost ~10% over the night.

Interestingly, you can also see around the same drain when the mobile radio was active, so it didn't make a huge impact on battery life, which I'm pretty happy about.

Disappointed and angry, wondering why my standby battery drain got so terrible, I reflected about what I did with the phone and which apps I installed. GSam was the only one. In fact, I restarted the phone and disabled Geo Location before going into airplane/offline mode and putting the phone away. There could have been an issue with a service. but unfortunatley, it was not.

This is proven by the following two screenshots:

My steps were:

Uninstall GSam, restart (not shown in the graph, did it before recharge cycle was complete), Full charge, unplug, let it sit, check for messages, then use the phone heavily.

After that switching airplane mode with wi-fi on (as usual) and leave it alone for the night. Location services were enabled on power saving (battery saving ?, don't know how it's called) mode.

The left screenshot (2:57am) shows the battery drain after I got back from watching a movie. It's pretty good considering the signal changed a lot during this time. Then I toggled airplane mode, reactivated Wi-Fi and watched some videos on my phone, checked out a gaming livestream, replied to messages and went to bed after that.

The battery percentage on the left (2:57am), after watching streams and videos and messaging, was 85%

The battery life when I woke up was 83%.

So I only lost 2% over night when not having GSam installed.

I do not think this is coincidence.

Everything was great before installing GSam, and everything went back to being great after uninstalling GSam.

Now, lastly, I am not saying GSam is a bad application.

It's great if you want to find out why there is abnormal battery drain on your phone. The statistics are great (battery percentage and temperature etc.) because with the in-app graph you can see much more than the default battery graph will ever show and the "app sucker" is very detailed providing active time, CPU time, percentages, even detailed wakelock information.

You can track down evil apps that like to eat your battery perfectly.

But after you're done tracking, it could become noticable that GSam itself will drain battery.

So, to all people with GSam:

It may be a possible cause of additional battery drain for you. Since every device has a different setup, this is not necessarily the case though. For kj2112 i.e, it is not noticably draining battery.

Greetings, have a nice Sunday and please forgive possible grammar errors in the text, English is not my native language.
