[Samsung Galaxy R i9103] Hypnagogia:
2013-03-19 Nightly

Hey guys, I'm fairly new here and new with the whole flashing business, my brother used to do it all for me. My first flashing that I ever did was cm-10.1-20130222-UNOFFICIAL-i9103 along with Butter Kernel 0.1. Yesterday, I flashed the 03-19 nightly along with Butter Kernel 1.1 weekly, so now I'm able to compare those.

The battery life on the unofficial release was simply AWESOME! It lasted a whole day and I still had well over 30% battery left, even with playing games on it. That never happened before on ICS, had to charge it twice a day when I played something. Not with the unofficial CM release.

The situation on this 19 nightly is a bit different. I charged it before going to sleep to 100%, and it's now at 13 hours 19 minutes with 53% charge left, and I haven't played anything and WiFi was even off. When I looked at the battery status, these were the readings:

- Google Services: 77% (CPU Total 0s, Keep Awake 49s, Data sent 38.56KB, Data received 61.55KB)

- Screen: 7% (Time on 28m 30s)

- Cell Standby: 6% (Time on 13h 18m 54s, Time without a signal 0%)

- Android OS: 4% (CPU total 3m 8s, Keep awake 7h 36m 8s)

- Phone Idle: 4% (Time on: 12h 50m 24s)

- Android System: 3% (CPU total 2m 16s, CPU foreground 1m 19s, Keep awake 2m 42s, Data sent 2.02KB, Data received 1.80KB)

Have to say my Mobile Data is off. I'm not sure if it's because WiFi was off and Google Services constantly tried to connect or something. I'll give it another day to test this or maybe even try the new nightly, but that's how it is now.

SetCPU is showing max 1000 MHz now. I'm fairly sure it used to go up to 1300.

The readings are:

Freq (KHz)	Time (x10=ms)	%

216000	4846676	82.13%

312000	325815	5.52%

456000	373722	4.62%

608000	138168	2.34%

760000	39767	0.67%

816000	18498	0.31%

912000	3051	0.05%

1000000	256405	4.35%

Also, some of my apps went missing, while the icons were still on the homescreen - pressing them said "App not installed". SetCPU was one of them, along with a game. Some others had "com.xxxxx" instead of the app name, had to remove them from homescreen and put them back again. And it also made me update some manually, which weren't showing in the update list on Google Play, so I had to go through each on the list to check if they have updates. I haven't cleared the cache/dalvik, I just flashed the nightly and kernel over the previous unofficial release - like an update.

I also found other bugs that haven't been fixed since the unofficial release.

- Unofficial release had some MAJOR issues with VoIP software. Tested with Viber and Skype, both that exhibited a sound that was like completely slow-motion, made any conversation impossible. Haven't tested with the nightly yet.

- When you take a photo, and press back button to exit the camera, it flashes the LED.

- Mass storage doesn't show SD card (I'm not sure how to connect it through ADB). I'm using Total Commander with LAN plugin and sometimes AirDroid, so I can still transfer files on my phone via WiFi.

Overall, it's a good solid build. At first, after the flashing, it felt a bit sluggish compared to unofficial release, like flicking through homescreens would freeze for a fraction of the second, but seems it has settled down now and the speed is as good as it was previously. Really no complaints about that. It's heaps ahead of the ICS build I had before :D

Good work, guys. Keep it up and if if it's possible to iron the bugs and make this a really nice stable release. Right now, I'm concerned about the VoIP apps the most. Battery really isn't an issue for me, I'm used to it draining before much faster than this (though, admittedly, I play games on it too, so no wonder), and even this is quite acceptable. Like I said, I'll give it another night to see how much will it drain again, and I'll report back, but I'll probably give a 03-20 a try as well. And camera flash is just annoying, but not something I'd consider a major issues.

All in all, well done guys :highfive:

Of, forgot to ask. If anyone would be kind enough to point me to the CRT thingy when you turn off the screen, the links I've stumbled upon seems to be dead.

It's like updating software on a computer, nothing would happen to it, unless there's some serious bugs in the software.
