Why is the battery life changing?

[Android Central Question]

I've had a LG G7 Thinq for over a year now and had no problems until recently. The battery life on the settings said 12 hours of battery life and recently it began to say 8 hours. After this the battery has felt like it's been draining a lot faster. I just hope to know if this is something I need to worry about or not. If so what's something I can do before considering buying a new battery. Thank yoi

Can put it in safe mode and monitor it for little bit see if any 3rd party apps are causing this .

Welcome to Android Central! This can also depend on your usage habits, and which apps you've been using. Have you been using any new apps lately (especially games)?

It can also depend on your usage. If you let the battery drain down below about 45% before charging it, it will start to lose life after anywhere from a month to a year or two, depending on how low you let it go. (50% is the ideal charge point for longevity. 45% is the "I'd better look for an outlet" point. 40% is the "I can't charge it, so I'm turning it off" point. Lower than that is the "I'm shortening the life of the battery" point.)

A year? You can totally ruin a battery in a year (where "totally" means it won't take a charge). Or you can stay between 50% and 100% (as soon as it reaches 100% disconnect the charger, or charge to 99% - which is what you're at the moment the indication is "100%"). Then ... I had to replace my Note 3 battery after a little over 4 years because it started swelling, and if it popped, the stuff that came out would damage the phone. It still works 2 years later, I just won't leave it in the phone. But I consider that a manufacturing defect - there was nothing I could have done to prevent that. My other Note 3 battery [I got one, my wife got one] is still going after just over 6 years. About 97% of capacity. Shut off every single time at 50%, for 6 years. They don't last forever, but long enough that ... who wants the phone? I still have a Samsung Precedent, with 2 good batteries. It's totally useless these days, it uses 2G for voice, which Sprint no longer supports. But the batteries? About 8 years old and still going strong. (I keep them charged - about 2 or 3 times a year. The phone can still be used to watch videos, it can be used on WiFi, etc.)
