Does your iPhone lie about how much battery power it has left? Apple constantly seems to be “trying to fix” these bugs which are unexpectedly causing our iPhones to die at a high battery percentage, but the issue isn’t necessarily a problem with the battery. So, if your iPhone has suddenly died, here’s what to try before taking it to the repair shop!
Check the Battery Indicator is Updating
If you have an iPhone 6S or 6S Plus, they encounter a problem in which the battery power indicator becomes stuck. This occurred when the users time zone changed and/or they manually updated their clock. If you think this issue could be affecting you, go to your settings app and enter the general tab. Under Date and Time, make sure that “Set Automatically” is turned on.
Force a Restart
Whether you simply turn your iPhone off and back on again, or fully restart your iPhone, sometimes the easiest fix does work! To turn off your iPhone (as long as it’s an iPhone 7 or later) press and hold down both the Sleep/Wake button and a Volume button at the same time.
Drain your iPhone Battery to 0%
Lithium ion batteries are most optimal when kept between 10-85%. When your phone reaches 100% while still plugged in, the battery will drop to 99% and the plug sends more juice to get it back to 100% – which can damage your battery.
If your issue is with the indicator and not the battery though, you can leave your iPhone to drain completely to 0% and immediately recharge to 100% for the reconfiguration. Just don’t leave your phone charging for too much longer after the battery is full.
Update to the Latest IOS
Older IOS versions had a safeguard to shut down before power malfunction, in the case a resource-heavy application spiked usage when the battery was already drained. The latest the version of IOS, the better the fixes from Apple.
Back-up & Restore as New
Is there still a problem with your iPhone battery? It’s probably time to start backing up your data and updating the software. If you’re not comfortable with this, head straight to the apple store. Otherwise, connect your iPhone to your computer and launch iTunes.
- From iTunes, choose “Back Up Now” – this will make the most recent backup of the iPhone and everything on it (you can also backup to iCloud if you want) – wait for this to finish.
- When the backup is complete, choose to “Restore iPhone” from the iTunes options
- Let the restore process complete, when finished the iPhone will start as if it was brand new. In this setup process, choose to restore from your backup that you just made
Try a DFU Restore
A Device Firmware Update (DFU) restores your iPhone’s software and firmware, so it’s an even deeper type of restore than putting your iPhone into recovery mode. The problem with a DFU restore is it will also completely clear your phone from all personal data, including current settings, contacts, photos, music – everything will be erased.
If you still want to go ahead with a DFU Restore, I advise you to follow an online guide, such as this one.
Still having Problems? Upgrade your Battery or iPhone!
If your iPhone is older than two years old, chances are your iPhone battery has reached the end of its life. You can get the battery replaced at your local Apple store, or you may opt to replace your iPhone entirely.
Note: if you’ve had your iPhone for less than a year, it’s under warranty and you can have your battery replaced for free.
