On the other hand, Minecraft PE is now unplayable on my iPhone 4, as neither the touch controls nor the camera do react to my finger tips anymore - due to this bug.
Also, when speaking of heavy framerate drops I mean an estimated 0.5 FPS with ~40 entities not being visible to the camera.
As long as this bug is not resolved, MCPE should be marked as unplayable or incompatible for iPhone 4 and lower to not displease users who might buy or update MCPE on a version greater than 0.14.1.
Another solution might be to give users the ability to stay on a specific version of MCPE and/or give them the ability to downgrade their MCPE.
Decisions are not up to me, but I think these problems could have affected customer satisfaction in a serious way and they will keep affecting customer satisfaction unless there is at least some kind of solution. Some customers might feel really betrayed when realizing: Whoops, the app I have spent 6$ on does not work on my device.
It also does affect 0.14.3. I can not compare to 0.14.2 or 0.14.1 but the performance drop still exists.
I think this is more or less intended. The devs use a technique named "discarding fragments" in their GLSL shaders. Only the latest generation of devices can handle "discarding fragments" in a performant way, these can do it quite good though.
However, the performance problems are not cool. If you can modify the shaders, you can replace every line which says:
discard;
with
//discard;
. This, however, will make everything opaque and make you recognize another performance bug more easily (https://bugs.mojang.com/browse/MCPE-14383).
There are no third-party applications affecting gameplay or using up a lot of RAM during gameplay.

What I would like to add: The whitespace character cannot be typed with this bug existing...
Confirmed iPhone 4.
What I would like to add: The [...] symbol is not consistent as well.
What does lag? Does the minecart not move consistently with the user, or does the user not move consistently with the minecart? Does this bug affect the framerate? Does it affect server games? Does it affect single player games?
Also, search for possible duplicates.
