Today’s problem: iPhone 7 loses battery power fast

Hello. I hope you can help me I have an product red iPhone 7 that is relatively new (although secondhand, but it wasn’t used much by the previous owner), and I’ve always been one to take good care of my phone’s battery life. It has been working great since I first purchased it. However the phone died and I put it on charge for about half an hour. I went to check on it and it was awake, but only on 1%. It still had the indicator that it was charging, but it soon died again and two chargers in my room wouldn’t work – these chargers still work fine for my sister’s iPhone 6S. It wouldn’t turn on for a while or even show me the prompt to charge the phone when I held the power button down. I used my brother’s charger in another room and it works. I charged it to 99% and then went to bed, leaving it in standby mode, but when I woke up it was only on 40% and was draining very quickly while I used it (going down at least 1% every minute or so with only one app open, was down to 25% in less than half an hour). I wasn’t running the most recent iOS update and have since updated it to that one. Should I see Apple about this issue or is there something I can do to fix it? — Emma

Solution: Hi Emma. Like most iPhone issues a lot of users encounter, your iPhone that loses battery power fast problem can be caused by a software glitch, a bad app, or hardware malfunction. In order to know where the problem lies and whether or not you need Apple’s help in fixing it, you must do a series of troubleshooting steps. Since you’ve already did some of the essential ones like testing another charger and installing updates, here’s the rest of the things that you should do.

Uninstall apps

If this problem coincidentally occurred after installing an update, then doing this troubleshooting may also solve the loses battery power fast issue. Not all apps that you can download and install may work properly so it goes without saying that it’s your responsibility to screen what apps to add to your system. If you are the adventurous type when it comes to apps, you’ll most likely end up having problems from one of them sooner or later.

Unlike Android devices, iOS devices can’t be put to Safe mode to check whether our suspicion about bad apps is true. So, you should try to remember as best you can whether or not you installed something prior to noticing the problem. This is the only way that you’ll know if an app is behind this trouble or not.

Reset All Settings

Sometimes, iOS problems are fixed by simply returning system settings back to their defaults. This is where Reset All Settings option comes handy in this case. If you haven’t tried it yet, follow the steps below:

  1. Open Settings app.
  2. Tap General.
  3. Scroll down and tap Reset.
  4. Tap  Reset All Settings.
  5. Enter your passcode if prompted.
  6. Confirm reset.
  7. Restart your iPhone and check for the issue.

Check Battery Usage

Since you mentioned rapid loss of battery power, it’s also worth checking what apps or services are using up power most of the time. If you notice that an unknown app seems to be consuming a lot of power lately, or after you installed it, it’s may be a malware or a poorly-coded application. Removing it from your device may fix the battery drain issue you’re experiencing. To check Battery Usage:

  1. Open Settings app.
  2. Tap Battery.
  3. Check Battery Usage section.
  4. You should see two tabs: Last 24 hours and Last 7 days. Try to use each of them to get any pattern of abnormal app usage for the last 24 hours or week. If there’s an unknown app that keeps popping up on top of the list, try removing it to see if that will fix the problem.

While still at it, try to also use of BATTERY LIFE SUGGESTIONS to conserve power.

Wipe your iPhone with factory reset

Another good troubleshooting to do here is to completely wipe your iPhone to return all software settings back to their defaults. Some software bugs may not be removed by simply resetting the settings so a complete wipe may be necessary. Before you factory reset your device, be sure to back your personal data up to avoid losing irreplaceable files.

Here are the steps to factory reset your iPhone 7:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Erase All Content and Settings.
  5. If prompted, enter your passcode.
  6. Tap Erase iPhone.

Restore old backup

Some bugs may be associated with how a device is set up recently so if you have a backup from, say, a few months ago, before you encountered the problem, we suggest that you try to restore your phone with it. To do that, follow these steps:

  1. Connect your iPhone to your computer with the cable that came with your phone.
  2. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  3. Select your iPhone once iTunes asks you for the specific device.
  4. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore).
  5. Confirm by clicking on Restore button.
  6. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  7. After this factory reset, all software settings should be restored to their defaults.

Contact Apple support

Should all the suggestions above fail to fix your problem, that means you most probably have a bad hardware issue. To fix it, make sure to let only Apple repair your iPhone.
