Hi everyone! I bought new battery for Redmi Pro (omega) that has capacity 4700mah. When i inserted it capacity in security/battery remained on 4050mah (original value). After that i made nandroid backup and flashed new ROM to see if that will fix it but it didn't. Than i decompiled framework-res.apk and modified power_profile.xml (where this value is), recompiled, signed, zipaligned, made zip and flashed from twrp. Phone booted and again value remained the same. Additionally found option in 3c toolbox to change battery capacity but even after restart it doesn't change.. It's not that it just annoys me, it also shows wrong remaining percentage because of it and sometimes it skips 2-3% when charging and discharging..
Can someone tell me what am i doing wrong? Is there another way of changing it 'cause i googled for hours and this is the only value i found that changes battery capacity and it's realy annoying..?

Thank you guys in advance!

the original battery capacity of redmi pro is 4050 mah and the firmware know it. how could you insert a 4700 mah battery and assume that it will show it as 4700?

Hi! Thank you for answering. I assumed it will automatically recognize its capacity, and i was wrong.. but even so, why can't i change that value? It's just one number.. i don't care about what says in security/battery app any more, phone thinks that capacity is 4050mah and measures everything wrong. I changed few ROMs to see if that will "calm down" but everytime it skips a % or 2, sometimes even more.. It's a brand new battery, i don't want it ruined in a month or so.
***EDIT***
In the newest xiaomi.eu rom with 4700mah battery i get max 3.5-4h SOT, changed quite a bit ROMs and this is best i can get.
(i use battery optimization tweaks, l speed, kernel adiutor etc to slow down cpu and gain every % i can get)
That's just...wrong..

it wasn't a right move to put a higher capacity battery in a phone which originally came with a lower capacity battery, it might cause some problems to your phone. i recommend you to change it
