iphone 5 cant startup after charge for few hours

Hi there Liewminchuan,

If your phone is still not powering on, I would next try and reset the device with these steps from the article about that sort of issue:

If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on

First, try to force your device to restart.

• Forcing your device to restart won't erase the content currently on your device.
• You can force your device to restart even if your screen is black or your buttons aren't responding.

Press and hold the Sleep/Wake and Home buttons at the same time for at least 10 seconds until you see the Apple logo.

If it still doesn't turn on, I would next use these steps to see if there could be an issue with the cable, or power adapter:

If you can’t charge your iPhone, iPad, or iPod touch

If the battery doesn’t charge, unplug your device and try these steps:

1. Look at the connector at the bottom of your device and make sure it’s free of debris.
2. If you're using a USB power adapter, make sure it's plugged in all the way and the power outlet is working. If you're connecting to a computer, make sure it's on and can charge your device. To charge an iPad, you might need to use a USB power adapter and plug into a power outlet.
3. Try a different USB cable, USB power adapter, or USB port.
4. If everything seems to be working, reconnect your device and wait for 30 minutes.

If the issue persists, I would next reach out to Apple support directly:

If your device still doesn't charge or you still see an alert after trying the steps above, contact Apple Support.

Thank you for using Apple Support Communities.

All the best,

Sterling
