Just flashed to this ROM. Lets see how it goes

Hopefully battery life will improve

Performance is as par as MIUI but needs more optimization on some part.

I think battery is somehow improved in this ROM compared to MIUI7. I can feel it does not suck battery as much as MIUI7. When running on MIUI7, whenever the screen is on sure will notice percentage drop like water but its not the case in the CM12.1 ROM. I can barely see the battery percentage drop when I'm on the screen with this ROM.

Need to flash thru TWRP. Easy only to do. You can always backup your current ROM with its data and restore later if u dont like the CM12.1 ROM. I wish the CM12.1 was a stable release, I would be the first to use it permanently. For me it is definitely > MIUI.

Now reverted back to MIUI and installed Greenify, Amplify and Power Nap. Let's see how the battery behaves.

Lol, your phone/charger is probably faulty. Mine charges full in 1hr30min+ with the fast charging plug adapter xiaomi provided.

I have just underclocked the CPU to 1.4Ghz (Root needed) and battery life seems to be awesome (not as much drain as stock 2Ghz when using WhatsApp etc).

With 1.4Ghz, I dont feel any difference in performance. But I'm pretty sure when playing games, it will be noticeable.

Will update back after I test with a full battery cycle.

Yep, used this method :

But according to my view. Previously aggressive WhatsApp within 2mins, drains 1% of my battery. After underclocking it, it only eats up 1% after 5min of aggressive WhatsApp.

Anyhow, lets see how it goes and will update back.

Froze means what? Only black screen?

When starting up the phone, does the MI Logo appears? If yes, most probably software.

I have gotten almost near to 6hrs SOT with the underclock CPU.

Giving it a second charge cycle now and will post the next result here with the screenshot.

Does not respond to touch looks like a hardware issue to me . You tried to reflash MIUI 7 Global ROM already?

To install TWRP, need to flash the recovery.img via fastboot (Power + Vol Down button). Please follow this guide carefully :

You cant flash the TWRP using Mi Recovery. Tested it and it does not work. Only was is to flash it via fastboot. Please follow this guide carefully :

Good Luck. If you need help or stuck in the process, let me know.

Nope for Redmi Note 2 it is not possible. Actually it depends on ur recovery. Got two type of MI Recovery. The Malaysia set RN2 does not work when flashing the twrp through MI recovery.

Then ur set has the other type of MI recovery. I confirm 100% it doesn't work with the MI recovery on my device. Other users confirmed it too.

The only best way is to load the recovery.img via fastboot. I have done it and succeeded numerous of time.
