Replacement battery for HTC M9. Unlike cheaper batteries found on other sites, this one is fully compatible and won’t damage/ destroy your HTC M9. Bring your mobile phone battery back to full life!
Just like when you’ve purchased a new mobile phone, calibrating the battery is an important step to make. For mobile phones and tablets, after you have replaced the battery, charge to 100% and leave charging for 2 hours over full charge point. Use the device until it turns off due to no power. We advise doing this is the evening after a day of use. Maybe playing a HD quality film etc. Once done, charge the device to 100% without disruption. Although doing this once is usually enough, for ultimate battery calibration, repeat the process.
