Help needed

I'am having xperia mini pro ( mango ). Several weeks I was using FXP's CM 7.2, later decided to try LegacyXperia's CM 10.1, Installed it perfectly. Later that day noticed my battery drains very fast.. like 1 percent per 2~4 minutes. Thought to go back to CM 7.2, reflashed back succesfuly and the bug apeared.. I charged my phone to 100 percents, disconnected charger and battery drained to 0 per few seconds, phone turned off, tryed to turn on, but only red light keeps blinking. Connected to charger again, turned phone on, it says "charged" and 100 percent, but after disconnecting charger it dies again, can be my battery damaged or something? Tryed to wipe battery stats and clean phone under battery, nothing helps yet, any suggestions?

Try flashing your stock firmware with Flashtool. See if things are okay. If so, flash Rage kernel for CM7 (using command and not flashtool) and then install CM7. Rage kernel gets the best battery life in my opinion. Note that there are two Rage kernels. One for stock firmware and another for CM.

Fast battery drain of the P9000

I flashed the P9000 from 20160608 rom (rooted) to the new 20160810 rom (unrooted).
After the update everything works fine but the battery capacity is a lot lower. It drains much faster.
Fully loaded, without WiFi, GPS, and bluetooth, and only on stand-by, the battery drains from 100% to 15% in about 12 hours.
Before I unrooted the Phone by flashing it with the 20160810 rom the battery was OK. A full day on stand-by only drained the battery from 100% to 95%.
I did not accept this and flashed it back to the 20160608 rom because I was thinking that the battery would not drain that fast anymore.
Disapointment : The faster draining of the battery stays.
What can I do to get the battery life of the Phone back as it was before the updates ????
Something happened inside the Phone that was caused by flashing the 20160810 rom.
Lately my battery life also decreasad. i uses get 205 screen tiem for 1 hour but it has decreased, so i flashed 20160715 and will test it without fp
On last stock 20160810 rom on 2G network with WiFi my phone was ok.
It worked more than 2 days. But before flashing I made System reset, Full factory reset, Wipe cache partition and Wipe system partition in recavery. Then flash by Flash tool.
I don't know may be this is the reason that phone worked almost 3 days.
Now I am on CM 13 build 5, on this rom everything is ok except battery drain.

Mi A3 - Battery draining after last update

Hello to everyone, I noticed that after the last update 1st august 2022 the battery can't last for more than 1 day of normale use.
I don't know if it's a software problem (Android update) or just the battery that must be replaced (the phone has just passed 2 years)
