Question 'Android OS' is draining my battery

[Anderoider]

I have a Motorola G60S - I recently started noticing that the battery is draining pretty fast, about 10% every couple of hours. There's no apps running. No apps have been installed recently.

I've spent hours going through suggestions online, but basically when I looking at the Battery Usage from Settings, Battery I see 'Android OS' on 43%. Of course tapping on that does nothing so I can't get a breakdown of what is sucking the life out of the battery.

So I've enabled Developer mode and looked at the Services - this is sadly of no use whatsoever.

I've gone into the Apps from Settings and checked each one's battery usage individually but most are at 0% and only one or two at 1%.

So I'm very stumped - how can I find out which background app is using the battery so much?

Welcome to AC!

Are you on WiFi or mobile data ?
How's your signal as these can contribute to battery without being in the stats.

How long have you had this phone? It was released in August 2021, so the battery might be on its last legs.

For my device with android 15 Digital Wellbeing and Battery apps has a detailed list and graphs of what apps are most used an time used.

Thanks for the replies.

I seem to have fixed the issue now - I had forgotten that Facebook had been loaded onto the phone some time ago and although it was unused, since removing it I've not had any issues with battery drain

As an aside, my wife has the exact same phone - there's no Android OS battery drain issues on that but 'Mobile Network Standby' seems to be using up a bit too much (10% in five hours). What might cause that?

Good to hear that you figured it out for your phone -- yet another example of the FB app being terrible.

Regarding your wife's phone -- has her total battery life been significantly impacted, or is it just the percentage of Mobile Network Standby that you've noticed? If the total battery life is unchanged, then you generally don't have to worry about any fluctuations in the relative percentage of battery usage that a particular system component might exhibit.

If her battery life is down, then how's the cell signal? Poor cell signal is of course the most common cause of increased Mobile Network Standby, and this can still be the case even if you're relying on wi-fi.
