phones with removable batters were not as waterproof or dust resistant as they are now. phones with removable batteries were more likely to get damaged by the users when they are regularly switching batteries. phones with removable batteries were actually heavier because there had to be more protection between the battery and the rest of the hardware. phones with removable batteries also had cases available.
It's more to serve the manufacturers and carriers than the consumer's interests.
For one of the most expensive devices not to have easily replaceable LI packs is bs. High end cams, tools, DVMs, etc all do.
They're clever little rabid gerbils; they could do it if it $erved them too. It doe$n't $o they don't.
From the get go practice LI battery conservation.
>Keep device temps low, always below 100F, below 80F is better but impractical unless charging.
>With waterproof phones wrap a clean damp rag around it when charging to cool it. Under it when using it on hot days or if running hard/warm like when gaming.
>With new Samsung's enable fast charging and use only the 25 watt charger/fast charge cable. It yields more MAHs at a lower temp.
>Charge to 72%, avoid going over 90%
>Leave screen off while charging to speed charge, reduce temperature.
>Discharge to 30-40%, avoid going below 20%
LI's wuv partial cycles like this and will more than double the life many times.
On my Note 10+ this 30% duty cycle yields over 5 hours of constant use. The charge takes less than 20 minutes.
I charge like this 2 or 3 times a day.
Wear on the LI pack isn't even one wear cycle if kept cool a week in theory... we shall see how well it does.
This beats charging to 100% then suffering smaller and smaller MAHs of available charge!
With my usage rates charging the pack 100% would suffer noticeable damage in less then a year.
Soon I have less available MAHs ie use time then I do now using a limited duty cycle strategy.
This should add at least another year plus of life to the pack.
Even with fast charging the pack charges slowest below 20% and especially above 99% (always avoid this!).
Best charging range for speed seems to be from 40% to 72%; it goes at over 2% @ minute.
The Accubattery App helps you visualize the wear cycle.
I'm still playing with the free version of it. It displays battery temp which is useful too.
