Hi
Potential free battery replacement
There is an iPhone 6s Program for Unexpected Shutdown Issues. Follow the instructions here to check your iPhone's eligibility for a free battery replacement and, if appropriate, to arrange service:

Warm when charging
Apple advises that it can be normal for your iPhone to become warm when using it and also in other situations including when charging it, first setting it up, restoring from a backup and after a software update (when your iPhone may perform background tasks, such as when apps re-index or re-analyse data). The exterior acts as a cooling surface, transferring heat from inside the iPhone to cooler air outside.
Be sure to follow Apple's instructions here:
Keeping iPhone, iPad, and iPod touch within acceptable operating temperatures - Apple Support
Apple also notes that charging your iPhone when it is inside certain styles of case may generate excess heat, which can affect battery capacity. If you notice that your iPhone gets hot when you charge it, Apple advises that you should remove it from its case before charging.
When charging your iPhone, be sure to follow all of Apple's safety and handling guidelines, including those detailed here:

Battery life
If your iPhone is not eligible under the iPhone 6s Program for Unexpected Shutdown Issues, then - depending on the nature of the issue - it may require battery service.
Before contacting Apple, try the following steps:
If you have not yet done so, update your iPhone to the latest version of iOS (starting by making a backup):
Restart your iPhone (normally):
Check which apps are responsible for the battery usage:
- Go to: Settings > Battery > under Battery Usage, select the Last 24 Hours tab.
- Address any issues with potentially problematic apps (such as by removing and reinstalling them).
Follow Apple's tips for maximising battery life, as detailed here:
- Batteries - Maximizing Performance - Apple
- About the battery usage on your iPhone, iPad, and iPod touch - Apple Support
When charging your iPhone, follow the instructions in the following support article, including:
- Checking the charging port for any debris.
- Using only a genuine Apple cable or an Apple-certified (MFi) cable.
- Apple recommends using the supplied USB Power Adapter.
- If your iPhone, iPad, or iPod touch won't charge - Apple Support
Check whether the issue persists after restoring your iPhone to factory settings:
- Back up your iPhone (you may wish to encrypt the backup, if using iTunes):
- Restore it to factory settings, with a fresh copy of iOS:
- Check whether the issue recurs before or after restoring from backup:
If the issue persists - and/or if you remain concerned that your iPhone gets warmer than it should do - then I suggest that you contact Apple Support (remote diagnostics and mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider with a view to having your iPhone checked and, if recommended, serviced:

- Elsewhere: Apple - Support
