Zte Axon 7 insane battery drain

[FoxAxe]

My Zte Axon 7 is quite old not 2y 9months but this kind of battery drainage is unacceptable!

So in 48min 2sec it lost 100% of its battery just by watching Youtube. And it even says 99% went to the screen (brightness was about 50%) any good reasons and help fixing this. Is it hardware?

Battery needs replacing, looks like that one had enough.

Seems pretty normal to me for a 3250mAh battery after

Perhaps a factory reset might help?

Also, it will help to turn off data/wifi whichever is not being used. Seems you are on public wifi and using a VPN.

Not using a vpn. The phone is only connected to wifi. Doesn't even have an Sim card. Still the power manager says that over 80% is going to Rf signal. I don't see why it would it doesn't even have internet access apart from wifi but the wifi battery usage is in a different category only about 7%

How often do you drain and recharge the battery? Honestly, at almost 3 years old and from the use you seem to put it through, it seems perfectly feasible that the battery has had it. Battery life isn't dictated by years, it's dictated by charge cycles.

Might want to go into developer settings and ensure "Mobile data always active" is disabled

It is

After a little over a year, it's been in constant charging since I use it as a secondary phone.

Thats a problem. Continually charging when its already at 100% puts stress on the battery. The best state to idle the battery is at around 50-70%. Even better if its turned off.

Yeah but it stops charging after its full and tve battery is factory capped into reasonable precentages when it says its 100%it really not. At least my laptop's battery lasted much better when it was charging almost always. We had 2 of the exactly same laptops one normal use and one charging.

And where did you hear that from?

I just remember it from somewhere. So, might be fake news

That's horrible for batteries. You've killed it, this is of your own doing.

Unless you can guarantee both had the exact same usage (which they haven't), that's not a conclusion you can jump to.

My laptop, for instance, has a setting where it will limit the charge to 80% when plugged in, precisely to slow battery degradation.
