Your iPhone is a minor miracle, a pocket-sized computer that has 250 times more processing power than the original IBM PC. A real modern marvel. However, this awesome power requires a decent battery in order to keep it powered all day. I’m going to tell you exactly why your iPhone battery drains so quickly and exactly how to fix it. I’ll explain how you can get longer battery life from your iPhone without sacrificing any useful functionality.
There are 2 things to consider when it comes to battery life in your iPhone:
- The software on your iPhone
- The battery itself
You would imagine that the solution to most of your battery issues would be to replace the battery with a new one. But this isn’t necessarily the case as there are loads of things you can do within the iPhone software that will lessens it’s impact on your battery and allow it to last longer. Having said that, keeping your battery in tip-top condition is a sensible thing to do as it ensures it charges, and retains it’s charge, for as long as possible.
The software on your iPhone
The majority of battery issues are related to the software on your iPhone and aren’t caused by an issue with the battery itself. I’ll say that again. The majority of battery issues are related to the software on your iPhone and aren’t caused by an issue with the battery itself they are caused by the way your iPhone is configured.
If you follow the instructions in this article then I guarantee you will see an improvement in your battery life.
So what are the iPhone setting tweaks I would recommend so your battery lasts all day?
Tweak 1: Mail Setup
When you setup an email account on your iPhone it will automatically be configured to check for new email message constantly using ‘push’ mail. This means that the iPhone is always connecting, checking, and downloading any new messages. This process alone drains your battery massively. If you are a corporate user on Microsoft Exchange then the drain will be even greater.
So the convenience of being informed that a message has arrived on your iPhone instantly is paid for in battery life.
This method of usage makes even less sense if you are waiting for an urgent email as you probably manually check if the message has arrived in your inbox while waiting (you do this by sweeping down on your inbox). However, no matter how you configure your mail this manual method of instantly checking will always work instantly so anything urgent will appear immediately. So you are probably draining your battery unnecessarily.
So what is the best setting for your mail to preserve battery life? Well I would recommend ‘fetching’ new messages every 15 minutes instead of using ‘push’ to constantly check. To reset your mail from push to fetch:
1. Tap Settings
2. Scroll down and tap Mail, Contacts, Calendars
3. Scroll down and tap Fetch New Data
4. Click the ‘Push’ button at the top to turn it off
5. Scroll to the bottom and choose Every 15 Minutes under Fetch.
6. Tap on each email account and, if possible, change it to Fetch.
