[Galaxy S III Original Android Development] curiousrom:
S3 Battery Charging Current Monitoring & Battery Drain

I was going to try this move user app to system suggestion as I missed the clean & simple Galaxy Charging Current Free to test my new USB cable but checked before in Google Play & it just got updated & it's now compatible with rooted Lineage 14.1.

As shown in the screenshots attachments not only can I see the charging current change after unplugging/plugging the cable or when it gets near 100% but it now includes a charging log if you enable it in the settings.

Sometimes the S3 is very slow charging & that is a strange behavior that goes way back to stock 4.1.1. I don't mind most of the time but if I need to charge quickly the S3 that's when that Galaxy Charging Current is useful as well as for testing flaky cables/charging port/charger. Hit the Refresh button on the free version once in a while.

The S3 maximum battery charging rate using a power adapter with an output of 5v & 1 amp minimum is 1000 mA and 460-500 mA using USB connected to a computer.

More explanations from the app developer [MENTION=608864]abmantis[/MENTION] thread Galaxy Charging Current: Check if your device is charging correctly:

Other apps like GSam Battery Monitor and SystemPanel 2 (XDA thread) also show the charging current on S3 i9300 LOS 14.1 but they do a lot of other stuff and run in the background which you have to fight using Privacy Guard to keep your system clean.

30%/h Battery Drain

Everything is relative. If you have $2 and spend $1, you spent 50% of what you had. If you have $10 then that same $1 is only 10%. My point is if your battery is old or a bad Chinese clone replacement then the same power consumption looks a lot bigger when expressed in %. I wish there would be an easy app way to check the real mAh capacity of our old batteries.

This said that's probably some apps you installed because I don't have any of those on my S3 lineage-14.1-20171213 A *job.delay* search in the BetterBatteryStats thread returns 30 results currently including:

Broken Power Button?

I thought I had a broken power switch stuck in depress position so I popped out the plastic power button, vacuum cleaned inside & could click the motherboard's power switch with a piece of plastic. Went to my village's phone repair guy & not only did he have a dead S3 donor with a not so bad button but also a brand new Samsung OEM USB cable. The only one in a 1.5 hour mountain roads drive radius.

Check this video: Replacing the volume and power keys on a Samsung Galaxy S3

This video is funny to me because it takes more time for the guy to get the replacement button part out of the Ziplock than to install it: Power Button repair galaxy s3

So now I use Settings > Device > Buttons > Recents button > Long press action > Turn screen off to use less the Power button and Settings > Developer options > scroll all the way down > enable Kill the foreground app by long-pressing the back button for apps that I use only once in a while.

Just hit the Thanks button & all is forgiven. ;)

I included a holiday gift suggestion in the attachments for those out of ideas. :silly: I got those two for $2.50 shipped on Fleabay.
