Doesn't Replaceable Battery Mean Crap Waterproofing?
I like my Samsung Galaxy 7edge because:
- doesn't have the fingerprint sensor on the back
- does allow a memory card
- is somewhat waterproof (I ruined a Galaxy 2 back in the day by swimming with it)
- has quick wireless charging (I love it putting it in a cradle rather than plugging in a cable)
It's probably already difficult to make the phone waterproof while still leaving a USB port, headphone jack, and SIM / memory card slot. If the whole back came off easily to allow a battery replacement, I can imagine that it would be hard to keep water from leaking around the edge.
I also have had horrible experience with obtaining a replacement battery for my ASUS ROG laptop. ASUS doesn't supply them. The ones for sale on Amazon etc. are cheaply made pieces of crap that either don't work at all, hold about 20 minutes of charge if they do work, and give up the ghost completely after 11 months into the 1 year guarantee.
If the desire for a replacement battery is more because of running out of juice during the day than extending the life of the phone, then one of those external batteries is probably a better alternative. I have one about the size of the phone itself that can charge up the phone 4 times, and can be used with any phone that has a UBS charger connection.
So if you have an old(er) phone and there is no longer an official replacement battery from the OEM, I'm wondering it getting a quality replacement is possible. If not, then the battery replacement feature trade-off versus waterproofing looks even worse.
