Dying battery, dying phone, or something else?

My nexus 5 (just over two years old) has taken to switching off at apparently random moments. If I turn it on again, it usually shows about 3% battery life; if I then turn it off and on again, this sometimes goes up to around 25%. If I plug it in, it starts charging from a higher figure. Here's a recent example of the battery charging screen:



I've tried downgrading from Marshmallow to Lollipop, but the problem continued.

Does anyone have any ideas about what's going on, and whether it's fixable? Thanks.

I would speculate that your battery is toast.

Thanks -- at least if it's only the battery, I can try replacing it. Spudger at the ready.

Try to do hard reset your phone it will resolve your problem as same happened with my nexus 5 also.

Thanks, but this didn't do anything for me (there were several resets involved in the Lollipop downgrade). I have a new battery on the way, so I'll see if that helps.

Update in case it helps anyone with the same problem: after a second replacement battery (first one was a dud) all is well: longer battery life, and no random shutdowns. Thanks.

Try to upgrade OS.
