As we know that android version 5.1 is the complete bug free version of the lollipop that users faced memory leak, poor RAM management, heating problem and lags etc before with version 5.0.1 and 5.0.2. Lollipop 5.1 has more introduced animations & good battery performance.
We flashed mokee 5.0.2 and cm 12 on the device and did the comparison before

Now today we are about to flash Cm12.1 on Redmi 1s:

First of all you have to download the Rom & Gapps 5.1 from the link down below and place it in your external SD card. Then

• Boot into twrp recovery mode. (Power off your device and press Power+Volumeup button for few seconds).

• After getting into recovery mode then select Wipe option.

•  Swipe to wipe them.

• After that hit back and go to the Install option and select install zip from SD card.

• Browse for the Cm12.1 Rom file that we placed in the SD card & swipe to flash it.

• When its done hit back and flash the Gapps 5.1 zip too, like you flashed Cm 12.1 and hit Reboot after when its done.

• It will take time to boot so be patient.

How was the experience with Cm12.1 on Redmi 1s?

After installing Cm12.1 and using it for 5 days with all of my apps installed I didn't encountered any big issues. The Rom has:

1/ Very brilliant Ram management. Never faced any lag via multitasking.

2/ Awesome battery performance. The battery now on Redmi 1s is giving me backup that it never did before. Managed to use the phone for 38mins without the power save mode on approx 2-4 percentage battery left.

3/ Calling experience was great. No lag! no distortion!

4/ You can move your installed apps to your external SD card. To set the default preference for installing the apps on your ext SD card gotoSettings>>Apps>>Preferred install location>> Select Removable SD card.

5/ The AnTuTu X benchmarks came out to be 19052 (On performance mode).

What are the bugs?

</bug 1> After settling down with all my required apps installed. Sometimes the google keyboard crashes!. Not that too often. (You can ignore that)

</bug 2> Dialer App reboots the whole device whenever you run the USSD code. This bug is quite irritating but it doesn't affect while making or receiving calls.

</Update> Now there is no bugs with the latest Cm12.1 R7.
