Unstable battery life

[Zakhwan05]

I had a Lenovo a6600a40 running android 6.0...the battery is 2300mah...the problem is the battery draining rate is unstable...sometimes it stuck sometimes it is constant draining even though I am using the phone whole time

As you can see in the picture the graph is straight and then suddenly drop then straight again

The steep drops seem consistent with your usage, since the Screen On bar is solid during the steep slope, and more intermittent during the gentler slope. What are you doing during those periods -- playing games, or doing a lot of social media posting?

Im sure im using the phone whole time during the straight slope...I am watching some youtube video during that time...and I am watching it by my eyes that the battery is stuck at same number for about 5 minutes and than it dropped very fast then stuck again

The graph clearly shows a lot of breaks in the Screen On at the flat slope, so either you're not quite remembering correctly, or the system is reading things wrong. Try wiping the cache partition: https://www.hardreset.info/devices/lenovo/lenovo-a6600/recovery-mode/

Does it also happen in Safe Mode? https://lenovomobilesupport.lenovo.com/us/en/solutions/HT501501
