There have been widespread complaints on technology sites launched by Android phone users that one of the latest WhatsApp updates drains their phone's battery life by up to 50% within hours, regardless of active use.

Some put the idea of ​​turning off the "intelligent control" of the battery, to stop this annoying bug, or disable the operation of "WhatsApp Web". Others said the app should be "shut down" before bedtime, to prevent battery drain during the night, or restrict background processing while clearing the cache.

Users pointed to alerts reaching their phones that "WhatsApp", took advantage of the battery during the "active use" for about 1.5 hours. Although the famous messaging app only opened briefly.

Many have blamed the WhatsApp 2.19.308 update, with OnePlus users appearing to be the hardest hit. There are widespread complaints on the websites of Android users through reviews of Google Play, OnePlus Forum, Twitter and Reddit.

In many extreme cases, users complained that Facebook's instant messaging service consumes nearly half of the phone's power.

Some Xiaomi, Huawei and Samsung Galaxy phones seem to be immune from an update that drains battery life.
