15.21 Why does it take a long time to charge my phone
when it heats up?
Huawei phones feature thermal protection technology. When the phone gets hot, it will
automatically limit the charging current to prevent discomfort for the user. You can help cool
the phone down by closing apps such as games and video players. Normal charging will then
resume.
15.22 If the phone heats up, will it reduce my battery
lifespan? Will the battery explode?
The battery lifespan is not affected: Your phone has been carefully designed and tested. It
features graphite heat sinks and an aluminum body for optimal heat dissipation. This allows
heat from the processor to dissipate quickly, preventing overheating. As a result, the battery
lifespan is not affected.
The battery will not explode: Your phone uses a lithium-ion battery. Even if the battery is
punctured, it may emit smoke but will not explode. In addition, your phone uses Huawei's
unique power saving technology and thermal protection applications. In extreme
circumstances, the phone can power off automatically to ensure that it does not overheat.
