After 4 years....

No, that is an uncommon result but it does happen for some.

my nokia 1100 battery has been going since 2004

The battery in my Samsung phone failed* after around 4 years but it was a replaceable item. However, sourcing a good replacement reasonably priced battery from the fake "genuine" crap out there is possibly not easy.

For reasons unrelated to the battery I've just purchased another phone and one of the settings is to only charge the battery to 85% capacity "to extend the life of the battery". This has a fast adaptive charging capability.

Last night I noticed the screen wouldn't close properly on my Huawei laptop, took the back off, battery is puffed up, manufacturing date Jan 2018, so about the same age ...

I'd hope not. Most do balloon a little but seldom crack the cases as there is room for it. Its not one of that model that kept on exploding is it? Brian

Not got anything to say then? Brian

I-Phones have the charging management for ages now. I do wish, however that companies would go back to supplying the charger, since I have a sneaky feeling a lot of early failures are due to cheap pound shop chargers that are crap. Brian

That's probably not what Huawei had in mind when they refer to their Matebook 16s "84Wh super-large battery". :-)

If it isn't too difficult, it might be of interest to dismantle the battery to see whose make of lithium cells is inside. Do Huawei make or brand their own?

FWIW, I had a Huawei smartphone (Y300) for almost 8 years (replaced last year) and never had a problem with the battery.

The Natural Philosopher brought next idea :

It can happen, often the warning to heed will be reduced battery capacity first. A while ago, my phones battery capacity became less predictable, so I got a new battery fitted. The original had swollen a little, but not enough to split the phone. My usual regime was phone mostly left on charge, on it's stand - which is bad. I now have it on a Smart Plug, only switching on for a few hours each night, ready for the next day.

I do likewise with my car, that gets a 20 minute boost each day via a Smart Plug.

I hope you like the no eyebrows look, LiPos tend to burst into flames if pierced.

Looks like the battery is Huawei branded

though there appear to be multiple types of flexi-ribbon connector, so I'll have to take mine apart to make sure which I need.

Keep your explosion containment pie dish handy!

I have never tried dismantling a soft walled Lipo battery... are there even identifiable individually cased cells inside?

I think it's just alternating layers of coated foil/insulator

I banged a nail through the last one and it did nowt, chucked it in a tub of water, still nothing ...

The smart phone may be in charge (no pun intended) but with modern phones and fast charging the wall wart chargers are adaptive and can give different voltages and currents under command of the phone. A third party charger may not give the same results as a manufactures compatible item.

My charger outputs 9V at 1.47A (15W) or 5V at 2A (10W). Other fast chargers can be found with an additional 25W output capabilities. Some third party chargers I've seen claim a 45W output.

and the weather has been quite warm.

I went to a reasonably reputable shop in the local town where a E European guy fixes phones. he charged £40. It seems to be a pukka replace and reglue event.
