Any specific app you can recommend?
It has been a while. I done it on my other Samsung Galaxy S4 active. Battery was terrible on that one. Done brief research.

1. Apparently best way to recalibrate is to follow a physical recalibration. That involves draining your phone to 0 and charging to max and few more steps.... Check youtube. They have some good videos on that.

2. Apps apparently only delete the calibration data in your phone. The phone will then try to rebuild the file from scratch, not knowing previous usage and charging characteristics. The only moment this could be usefull is when your data has become corrupted.

Not sure what app I used. Like i said it was a while. The one with highest score and good reviews would probably be a good start. :(

Good luck :D

Tried to calibrate battery, as I mentioned couple of post before. During the night, I think battery went down to 0%, but I am unable do charge the phone. It's stuck at Lenovo logo. When I plug in charger, nothing happends. No LED indicating that phone is charging. When I entered fastboot and press shut down, it shuts down. Then I again, plug in charger, red LED blinks for a second and it again shows Lenovo logo. Tried also connecting it to PC, no result. Can't enter the TWRP either.
Any ideas?

Looks like I lost TWRP and rom, I have no idea what has happend. Now I cant install TWRP, I mean it shows proper installation but when I do fastboot reboot recovery - phone doesnt respond. The same with trying to flash stock rom. It flashes all chunks of rom+recovery, but after trying to reboot - BIG NOTHING.

AccuBatt seems to calibrate without having to drain the battery. To be on the safe side, give the phone access to the necessary files via root or ADB according to Gsam instructions.

Can you enter bootloader? Vol down+Tun on button hold. Also do you get blue LED? when it switches off?

on old batteries: Do not use until it shutdown at 0% otherwise the device will be bricked

Briefly tried the rom, fluid and good, copy and paste works despite some user said that, btw the apps I mentioned earlier can easily downloaded on play store (writing for no confussion, not the roms issue)..

..but there seems an issue, gradually alarm volume increse doesn't work (also tried the google clock app) I would say... actually alarm CAN NOT ring! You need to open the screen for alarm working properly or you miss the alarm.. Can someone test this? This is a killer for me..
my bad, alarm works properly, will test gradually volume increase and report it.

edit: yes, gradually volume increase in alarm works, power on alarm also works, thanks for the rom!

Sorry if this is a noob question, but how do I build this myself? I want to integrate signature spoofing and microG into this.

Edit: I have found out that the instructions are pretty much generic across all android variants; so if anyone else wants to know this, generic instructions for AOSP and LineageOS, and the specific/summarized instructions in RiceDroid/android github will work.

Installed latest build on my daily phone. Rom seems good.

Noticed a bug but couldn't tested much. When you connect to a wifi, if you lose connection (out of range or closed wifi on settings) you CAN NOT reconnect it. You must forget that wifi and reenter password, etc. for reconnecting..

Edit: I feel like (FACT) mobile data connection is slow, and its very noticable, tested with speedtest.

Edit 2: Also tested A13 Awaken and these problems still persist as well. Dealbreaker for me. Downgrading to A12 rom now. These need to be fixed. Thanks for the all work @Astridxx and other developers!

For me this update not work well, really slow on boot and lot of bugs when I make a migrate restore, on last work well. Also after restore my migrate backup every time I uninstall apps reboot UI, maybe Magisk? I don't know but I downgrade to the first and all work again. Thanks for this awesome room

The rom is stable and fluent, but I have a problem, when I talk to the other party, the voice of the other party sounds like acoustic and I can't understand the other party most of the time. This poses a problem. I think that the sound and headphone settings should be separate in the Lenovo parts settings. Thanks for your hard work.

    Kudos to @Astridxx for still working on the Lenovo P2, this ROM is far better than the previous Android 12 ROM. Thank you so much for your efforts.
