Huawei P9 – Device Is Charging Slow – What to Do?

Does it take your Huawei P9 forever to charge? Slow charges can be particularly frustrating if you are a busy person who relies on their phone, but there is no need to stress too much about it.

Huawei P9 - Device Is Charging Slow - What to Do?

Problems with slow charging are easy to fix and usually boil down to certain hardware or software issues. We’ve selected some tried-and-tested methods to troubleshoot and deal with slow charging times on your P9.

Check Your Hardware

The USB cable and the wall adapter that come with your P9 are crucial for optimal charging time. In other words, using a third-party cable or wall adapter might result in recharges that test your patience.

These pieces of hardware are often tossed around, bent, or stepped on. Some damages are thus imminent. You should inspect them for cracks, breaks, or other physical flaws.

It’s also important where you plug your charger – wall sockets usually deliver the fastest results. You can expect your phone to recharge somewhat slower if you keep it connected to your laptop.

Lastly, the Huawei P9 features a 3000mAh battery which supports fast charging. However, you get a more standard 5V/2A adapter that fully recharges the phone from empty in 2 hours and 15 minutes.

Potential Software Problems

Once you make sure that there’s nothing wrong with your hardware, there are a few software issues that you should get out of the way.

Background Apps

A bunch of apps running in the background eat into your battery. These apps can also affect internet speed, so it’s best to kill all the apps in the background.

1. Tap on the Square Icon

This action reveals all active background apps.

2. Hit the Bin Icon

A single tap on the Bin icon removes all active applications from the background.

Tip: If you want to keep one of the apps in the background, pull on it and tap on the lock at the top.

System Dump

A system dump gets rid of some bugs that can be the reason behind slow charging. Like killing background apps, this fix can also ramp up your internet speed.

1. Access Dialer

Type *#9900# and navigate to the bottom, then select Low Battery Dump.

2. Choose Turn On

After the system dump, you should experience some improvement of recharge times.

Get Rid of Third-party Apps

There is a possibility that one or more third-party apps have a bug that’s causing slow charges. You can uninstall the apps within P9 Safe mode. This is what you need to do:

1. Enter Safe Mode

Turn off your phone, then press and hold the Power button. When you see the Huawei logo, let go of the Power button and press Volume Down. Hold Volume Down until your P9 restarts and release it once Safe Mode appears on the screen.

2. Navigate to Downloaded

Take the following path to reach the installed third-party apps:

Menu > Settings > More > Application Manager > Downloaded

3. Select Apps

Chose the apps that you want to remove, hit Uninstall, and then tap OK to confirm.

Note: Exit the safe mode by restarting the phone.

The End Charge

In general, problems with slow charging are not that frequent with the Huawei P9. But if you do experience them, the tips and tricks above should help you fix the issue.

Your method to do a Low Battery Dump does not work on HUAWEI devices… I’ve tried it on a P9, P9 lite, P8 lite (2017), P10 & on a P20… it does not work on any of them!
i’ve discovered that *#9900# is a SAMSUNG code for performing a Low Battery Dump…
