Also, can someone explain to me why a removable battery is so important to some people?
You can use it exactly like a phone with a non-removable battery.
But it also gives you options.
1. Your phone stays out of the landfill and remains useful much longer.
- Pass if on after two years to someone else, who can use it for four years more.
- Use an old phone as a media player/book reader (like the Samsung Galaxy Player).
- Use an old phone as a dashcam with DailyRoads Voyager app.
- Use an old phone as a OBD II auto diagnostics tool with Torque Pro app.
- Use an old Nokia Windows phone with free offline Nokia Here maps as a GPS.
[Middle 3 above are real examples for me. 1st and last are future examples for me.]
2. Your spare power comes in a much smaller package.
- I go into the city occasionally with nothing but phone and wallet. So a teensie spare battery fits in any small pocket, while a power pack would be bigger.
- You can carry days and days of power (like 6 or 8 batteries on a camping trip) in the size of a deck of cards.
[Above are real examples for me.]
3. You can charge the batteries separately.
- Instantly have full power with no extra bulk when you need it.
- Becomes especially useful if your micro USB charging port on your phone is broken, and you don't have wireless charging.
[1st above is real example for me.]
4. Some phones offer additional features with a removable back:
- wireless charging back
- extended battery
- flip case that replaces the back.
[1st two above are real examples for me.]
Possible Drawbacks:
- may be thicker than one with a non-removable battery
- depending on the phone construction, the back might come off easily when the phone is dropped.
