Screw cell phones

[ZenGum]

Some things I have heard about phone batteries that may or may not still be true (if they ever were):
* partial charging creates a "high-water mark", beyond which the battery will not charge. For example, if the battery is at 30 % and you charge it to 80% then disconnect, after that it will not charge past 80% no matter how long it is on.
* This can be fixed by taking it to a professional battery maintenance service who will completely drain and completely recharge the battery, which is supposed to erase the high-water mark.
* You can do much the same at home, by completely draining the battery (just keep turning it on every time it goes off), then leave it in the freezer over night (I know, sounds like an urban myth and probably is) then completely charge it up again.

I repeat, I don't know if any of this was ever true or if it still is or if it applies to the batteries in your phone.

Good luck.
