How to fix Xiaomi Mi A1 Battery Drain Oreo Update

Welcome friends in this article I will share with you how I solved Xiaomi Mi A1 battery drain.  I will show you step by step how you can easily fix this battery drain issue.

Symptoms of the problem

This issue started around in May when I updated by stock Mi A1 phone with the Oreo Update. I not a heavy phone user and before Oreo Update, I used to get a standby of 2 and half days with a screen on time of 5 hrs 30 min. But after the Oreo update, I started getting almost half of the battery backup and some days not less than that.

Cause of the problem

It was really annoying, initially, I thought my battery has degraded but when I googled about lithium-ion battery life I found the normal degradation of a lithium-ion battery to be around 5-10% max after 1 year. Then I found several other people on forums complaining and even found a bug report on Xiaomi according to which they have excepted the problem and are working to fix it.  So this issue is a software bug in the Android kernel which prevents my phone from going into a deep sleep by causing unnecessary wake locks. I will be creating a separate guide to optimize android battery consumption for older android phones having normal battery degradation so that you can get longer stand-by and screen on times.

Steps to Solve It

As of now, Xiaomi team has not found a fix for it. But do not worry friends. I have found out a way using which you can easily fix it.

Step 1: Enable Developer Mode

Note: If you have already enabled developer mode you can skip to step 2.

1. Swipe Down to open the notifications section
2. Tap on the gear icon to open settings
3. Swipe down to go to the bottom and tap on system
4. Swipe down to go to the bottom and tap on about phone
5. Under this find at the bottom, build number tap on it 3-4 times
6. You will see a message telling that developer mode has been enabled

Step 2: Limit Background Processes to 3

1. Go back to the system settings section
2. Now you will see Developer Options tap on it
3. In this swipe down and under the apps subsection you will see Background process limit tap on it
4. You will couple of options select at most, 3 processes

Minor Side Effect

I have been using these settings now for almost a month and I have not encountered any major bugs because of it. However occasionally when I am browsing chrome and then switching to a different app I have noticed that chrome crashes apart from that no issues. These settings have restored my battery life to almost what was present before the Oreo update. Once Xiaomi team release a fix for this problem you can change back these three settings to there default values.

Alternative Solutions

I was able to resolve the problem by analyzing my battery stats using the default android battery consumption indicator as well as some third-party apps. There can be many other reasons for android battery drain.
