Huawei is rumored to include a feature on HarmonyOS 3.0 that allows users to make a call with a drained battery
According to the post on social media by this tipster, whose background is unknown, the new emergency battery mode will somehow allow you to make a call even after the battery runs out. The feature will be part of HarmonyOS 3.0 which will sport this feature and come pre-installed on Mate 50 models. Along with being able to make a call, users will supposedly be able to send text messages and scan documents or location codes.
Extreme Battery Saver available on select Pixel models
iOS and Android allow users to reduce battery usage when the going gets tough. On iOS, users can access Settings > Battery and enable low power mode. This reduces background activity like downloads and mail fetching until you can fully charge the device.
Some Pixel users also have another option. Go to Settings > Battery > battery saver > Extreme battery saver will disable features that use more battery power such as Wi-Fi, hotspot, some network connections, “Hey Google” feature and some background activities. With Extreme Battery Saver, you can select the important apps that you need to keep while most other apps can’t get any battery power.
Some Pixel users can select the Extreme Battery Saver feature to get up to 48 hours of use according to Google
Translated, this Weibo article states that the Huawei Mate 50, running HarmonyOS 3.0, will make calls and more even with a drained battery
It will be interesting to see if Huawei actually has an emergency battery mode and what it promises to do. You can be sure that if Huawei offers emergency battery functionality, other phone manufacturers will consider adding it to their own devices. Considering that battery life is one of the main features that phone shoppers look at before making a purchase, this has the potential to be a big deal.
Even if Huawei is able to put emergency battery mode on the Mate 50 series, it probably won’t improve its prognosis in the smartphone industry as it is still unable to produce phones that support the 5G. Once the most popular phone brand in China, US restrictions have allowed other companies like Oppo, Xiaomi and Vivo to overtake it.
