How long does it take for a phone to charge to 100?

For average phone, it takes about 2-3 hours that your mobile phone is charged to 100%.

But in some cases can take longer:

  • You already have a bad battery.
  • Your charger is a cheap charger, not a charger which is recommended by your mobile phone manufacturer.
  • The temperature, where you are charing your mobile phone, is very low

Keep in mind that batteries inside the mobile phone can be different. Depend on battery capacity (mAh) and your charger it can take the different time that your mobile phone will be charged to 100%. 

How you can check battery capacity on your mobile phone

Most mobile phones have integrated battery inside so you can’t open and see what battery is using your mobile phone.

One way to check what is your current battery capacity is to download AccuBattery from Google Play. Inside this app, you will find what is the battery capacity of your mobile phone.

Example: From google play download app Accubattery:  Google play 

Inside app check battery capacity.

Keep in mind that chargers can be different too. You can buy cheap chargers which will charge your battery at 1A but it can damage your battery and it will take forever that your mobile phone will be fully charged. So use only charges which are compatible with your mobile phone and original chargers which are recommended by your mobile phone manufacturer!
