How To Fix BlackBerry Z10 Battery Dies At 30-15%

Although the Z10 has a removable 1,800 mAh battery, there are a few minor issues with this battery that users face. I recently received a complaint from a Blackberry user that said that every time his Blackberry was at 25%, the phone would turn off automatically. While some people might conclude that it was a software or update problem, it isn’t.

“I just recently bought a Blackberry Z10, it’s less than two months old, but surprisingly it can’t run on its battery level at / below 25%, I no longer get low battery warning signs, it just shuts off, what could the problem be? “
There are several reasons why your Blackberry Z10 turns off at 30-15%. One of the reasons is security wipes. Security wipes should be used with caution because when a user updates their Blackberry and performs a security wipe it will affect the calibration sensor, causing the battery to die at a low percentage.

Overheating or overcharging can lead to thermal runaway and cell breakage with Li-ion batteries. In extreme cases, this can result in a burn. Deep discharge can lead to a short circuit in the cell, in which case recharging would be unsafe. To reduce these risks, lithium-ion battery packs contain a safety circuit that switches off the battery if its voltage is outside the safe range of 3-4.2 V per cell. In the case of longer storage, the low power consumption of the protective circuit itself can cause the battery to drop below its cut-off voltage; normal chargers are then ineffective. Many types of lithium-ion cells cannot be safely charged below 0 ° C

By doing a full recalibration, your Blackberry Z10 battery will become more accurate. Below are the steps to do this:

• Remove the battery from your Blackberry
• Connect the original charger to your Blackberry without the battery inserted, VIA PC.
• Do not plug it into the wall socket
• Leave it plugged in there for 30 minutes
• Then insert the battery without removing the charger
• Let the Blackberry charge 100%
• When the battery is fully charged, remove the charger
• Let your Z10 discharge to 0% (perform CPU intensive tasks, play games, stream videos, etc.)
• Repeat these steps twice
• The battery then receives its charge cycle
• If you do this 3 times in 6 months, your battery will remain in good condition.
