Why Is Cell Phone Battery Dying Quickly. Let your battery drain completely from time to time and never charge it for hours overnight. Since it only hits a relatively small number of phones at once it.

Apple has designed the battery to be strong and safe for use. Network coverage is much better than it used to be but you still get the odd dead spot. In fact age is the primary reason your battery life gets shorter as your phone gets older.
High screen brightness poor signal too many background apps services old phonebattery etc.
A batterys voltage doesnt go down in a straight line so it isnt always a great stand-in for capacity. A lot of peoples have the habit of using our phones while charging as a result of we are an addict to our phones. My battery dies less than an hour after full charge to 100 and takes giant leaps forward toward death. For example battery charged fully overnight battery meter at 100 I send a text message 10 minutes later 80 make a 5 minute phone call down to 50 then scroll the internet for 5 seconds and the battery power less than 20 low power mode option pops up.
