Optimizing your iPhone: The Right Way to Save Battery Life, a Weird Trick for Freeing up Space and O

Optimizing an iPhone

As assistants we rely heavily on our smartphones, so I wanted to pass along these iPhone tips you may not know exist:


Don't charge your iPhone longer than it needs to be (try not to go over the 95% charge mark) and don't let it drain 100% either. "The 'lithium-ion' in the battery has its own level of 'stress'. If you increase the 'stress' of your smartphone by overcharging it, the battery life of your phone is ultimately shortened." (Source: 22 Words).


There are several photo and video hacks to free up space (source: New York Magazine):

  • If you don't want to back up and delete the photos on your iPhone (which takes up tons of space) then turn off the HDR setting. The HDR setting basically stores two versions of each photo (the HDR and normal version). Settings > Photos & Camera > Keep Normal Photo > unselect.

  • Next, disable Live Photos if you don't use them. With the camera app open, look for the icon with three concentric circles at the top of the screen. If it’s yellow, tap it.

  • Minimize the video quality (it's hard to tell the difference, so you won't be sacrificing quality). In the Photos & Camera setting and tap Record Video and lower the setting to 720p at 30 fps.

There's an interesting trick through iTunes if you get really desperate (source: New York Magazine):

  1. In iTunes find a movie that takes up more space than you have available.

  2. Tap “Rent” twice. Don't worry, you won't get charged because your iPhone will not be able to process the action; it will instead alert you that there's not enough space to do so.

  3. Now check your storage. It went up!

  4. You can repeat this process until your storage stops increasing.


Clearing your RAM is one way to speed up your iPhone. Press and hold your power button as if you were about to turn off your phone. When the “slide to power off” screen appears, press and hold your home button. (Source:

If you're looking for a particular word or phrase on a webpage, you can find it by typing the word or phrase in the URL/search bar at the top of the screen. You'll see a list of web search results - and search results from the App Store, Wikipedia and so on if applicable, but you need to look at the bottom of that list for a section labeled "On This Page", with the number of matches. Tap it, and you'll see that the results are highlighted on that particular webpage in yellow. Tap the arrows at the bottom of the screen to go to the next instance. (Source: Macworld)

FORMAT TEXT IN EMAIL In some apps like Mail, you can use rich formatting to make text bold, italics, or underlined. Just highlight the text you want to edit, and tap the arrow in the copy/paste pop-up. Then, choose "B / U" to access the formatting options. (Source: cnet)

In the keyboard, there are hidden symbols. Press and hold a letter, symbol or number and other options pop up for many of the keys. Example: if you hold the "e," you can find an e with an accent above. If you hold the "$" key, you will see symbols for other currencies. (Source: cnet)

SAVE AS PDF You can turn web pages into PDFs and add them directly to your iBooks app. Tap the Share icon, scroll across the apps to find Save PDF to iBooks. Tap it and the web page will be converted and added to your book collection. (Source: Macworld)
