My Phone battery is loosing it's charge fast

Suddenly my Apple phone runs out of juice 4 times more quickly than 3 days ago . What should I do !

Either the software has an issue making the phone think that the battery is dying or the battery is actually dying. More on batteries in a moment but first…

Here are a few things to do before wiping the phone and starting all over as a last effort:

1. Reset all settings. In settings go to General, scroll all the way to the bottom and select to reset. DO NOT erase all content and settings. First try just "erase all settings". While there you can also choose to reset network settings separately after a restart as well. This will make the phone forget what networks it knows so you'll have to rejoin your home wifi at some point.

2. Shut the phone off and restart completely.

3. Kill all apps, turn location services off, turn bluetooth and wifi off. Then continue to use the phone for a day or so to see if either of those could be at fault.

Things that kill battery the fastest are:

Screen Brightness
Location services (including Maps)

Limiting any of those will help preserve battery life.

Now for the dirty little secret of the battery industry: ALL rechargeable batteries, whether Energizer, Asus, Apple, Duracell, Dell, HP, Tesla or anyone else all rely on chemical reaction to hold a charge. As a battery ages that chemical reaction weakens. The more times a current is run through those chemicals inside a battery, the weaker the ability to hold a charge becomes. My estimate is around 450 full 100% charge cycles is around the useful life of a rechargeable battery. You phone has some battery information that can help. In Settings/Battery you'll find what your maximum capacity is. Over time this will go down. This is not a master plan by Apple to get you to buy a new phone. This is a limit to current battery technology. After about 1.5 years a batteries ability to recharge will begin to deplete.

If you've tried all these things and the phone is still not holding charge then the next step to take would be to wipe the phone completely and restore it from your backup. If even that doesn't do it, then it's time to consider the battery has failed.
