How to extend the life of your Infinix BL-40AX battery?
1.Please fully charge your device before using it for the first time. Because the Infinix BL-40AX battery is normally shipped in a partially-charged state. Please cycle your battery pack by fully charge (more than 12hours) and discharge(less than 10%) for 3-5times to reach maximum rated capacity.
2.Please don’t discharge battery to 0%, which is the most common reason among faulty batteries. It will damage battery if the device usually works at a critical power level ( below 3%).
3.Charge the battery before it runs to 20%. It is scientifically justified that charging battery at 20% till 80% will extend battery life to the longest.
4.If your Infinix BL-40AX battery won’t be used for a long time, please charge it once a month and keep battery power over 50%, remove it from your device and store it in an antistatic bag in a cool, dry place.
