But I'm pretty sure it's been 4 or 5 months. This battery now allows my phone to last my entire 8-hour shift doing pest control. I use my phone every 10 to 20 minutes... And I used it for navigation all day. I normally keep it plugged in just to keep it topped off at 80%, But I have gone a whole day without plugging it in just to see how long it lasts and it does the job. I do a lot of phone repairs so replacing the battery in my phone was no big deal. If you've never done it look up a YouTube video it's pretty easy. A hair dryer will work, a heat gun will work better. Review: High quality battery. Long lasting! - Improved battery life and the easiest to install. It’s capacity was much longer than the old one and even came with a tool kit.
