What do I do on my galaxy note 10+ to save my battery

Hi Bella,

I'm not clear on what you mean by "save my battery". Cell phone batteries are generally not considered repairable; when they fail the cure is almost always to replace them.

Perhaps if you describe what problem you're having we can help you figure out what the right course of action would be. What's the phone doing or not doing? When did it start? Did anything happen that might have contributed to the problem, such as being dropped, exposed to liquid, etc.?

The more you can tell us about it, the better an answer you will get!
