in how many years?

The first battery that came with the phone lasted a few years and I had no qualms about it's lifespan.

The second was another genuine unit and it lasted maybe a year. I remember being peeved about it.

That's when the overcharging issue occurred to me. The current battery is the non genuine one, and while the capacity between charges is noticeably lower, even when it was new, it has lasted me to the present day.
SiliconWizard:
Since there actually *are* 4.35V to 4.4V LiPo batteries, we can only assume that's what Samsung used here. It's almost impossible they have used regular 4.2V LiPo and charged them to 4.4V. LiPo batteries are not that tolerant. That would not just shorten their life to 1 year of use, but much less, with possibly bulging and bad stuff happening.

Which is not to say that some of the 4.4V batteries they used were not defective in some way. But not because Samsung incorrectly charges 4.2V ones to 4.4V. That's impossible to believe. They would just have made their mobile phone business unit explode with such a decision.

So, those batteries are commonly called "HV LiPo", sometimes coined LiHv. You can find more info there, for instance: https://www.grepow.com/page/high-voltage-battery.html

Did you unlock it? If you did it still sounds to me like a complete joke.

I came across something that I believe they had been doing similar with a few of their televisions with the led back lighting past the nominal voltages and in 3d more it seemed even higher with the voltages stated on the power supply but I was still confused as there seems to be single and double strings/arrays. They have a very short lifespan mostly 2 to 3 years according to the reviews and the best warrantly I get is 6 months for the leds. Now I don't know whether it was unintentional of deliberately.

On my Samsung J5 phone I get this little text on startup: Set Warranty Bit: Kernel"

Now I didn't buy the phone it was given to me and set it up in the way and I am happy with it for the few things I use it for.
Making calls, capture pictures and videos to which I use a tool that require the rooting:

Nice and easily, I take pictures, turn on the wifi on the phone, open a folder and copy them across.

I don't wish to use a stupid "app" to upload the pictures to some "cloud" just to download them again which I might as well use a cable.

One good reason I don't buy new phones is because of this:

It's often a major pain, as the old battery is often hard to remove due to the adhesive getting extremely hard to remove after 3 years. (Using hot air to dissolve the adhesive may help, but I don't feel comfortable heating up a large LiPo battery... ::) )

The last time i brought a new phone was in 2010 from a shop. I can't remember the name, could have been a Nokia, had a keypad, colour screen, standard looking replaceable lithium battery and had a lot of unwanted gadgets in the background that didn't really interfere with what I was doing but I switched them off anyway and it worked well. I think I got that for £40 and it came with a £15 preloaded Vodafone sim. It was basic and did everything I wanted it to do with no annoyance or disappointments and no excessive animations that I am finding these new phones..
