I had a China phone with amazing specs but it KEPT KILLING EVERYTHING.

Hardware is pretty useless if the software that drives it is useless. I don't know it probably works better in China all I know is that I went back to good old Samsung.

It's a pervasive Chinese phone problem. I've used many and they all have "Battery saving" features on by default, which means killing background apps after a while apparently. Battery life is great, but newly installed apps sometimes don't work as they should.

The market demands must be different there. I've disabled "battery optimisation" for all the apps I need to stay open (and some apps even prompt me to disable it!), and I don't have any issues in daily use.

That kind of aggressive process termination will be becoming less common since Android introduced freezer [1] optimization to put a background process to a completely unscheduled state.

Chinese apps are less optimized than western

if you run out of smartphone battery you are in much bigger trouble in China than in west since it's necessary to function almost everywhere, which is why they have rental powerbanks stand literally in every restaurant and every small grocery shop, you are never further than like 5 minutes walk from one in urban area

btw you can always put app to protected/not optimized list which usually solve problems with most of the western apps on Chinese phones (essential Chinese apps like WeChat are on the list by default)

> some apps even prompt me to disable it!

That's social engineering to get themselves more background network activity. I wouldn't trust such an app.

well health tracker which stops tracking when it's battery optimized isn't very useful, is it?

I have had many chinese phones (Huawie, Oppo, Xiaomi) over the years and the things they choose to kill in the background is odd. Web browsers and almoat any kind of banking app will be killed in minutes if not seconds. VLC... Depends on the day could be minutes or days. No idea why that one.

Hard to tell if it something I am doing or not. I will say with all these phones and everything google turned off I typically get 3-4 days per charge but that really depends on what your usage is.

It's because of a lack of centralized push message service. Here we have google cloud messaging to handle notifications for all apps. They don't have google in china, so each app establishes it's own connection to it's servers and that kills the battery. If you buy the global version of those phones it's often better.
