One thing is for sure and no one will deny it. The battery life on Galaxy Watch 4 & Galaxy Watch 4 Classic is much lower than we expected. Galaxy Watch 3 powered with Tizen OS can easily run for two days, but Galaxy Watch 4 series on Wear OS 3 roughly run for a day. The Wear OS platform has this serious problem, and there is no solid answer yet. Now, to tackle this issue, Samsung may increase the battery capacity on Galaxy Watch 5.
Yes, as per the documents that appeared in regulatory filings, Samsung will increase battery size on Galaxy Watch 5. As per the filing, the battery capacity of the next smartwatch will be higher than the Galaxy Watch 4 40mm version. On the current 40mm variant, Samsung has packed a 247mAh battery, and the upcoming 40mm variant may get 276mAh battery power. The model number found with the SM-R900 will be the next upgrade of the 40mm Watch 4. The appeared battery carries the part number EB-BR900ABY in the document.
It is a good indication Samsung is doing something about the battery life of its flagship watches. The next Galaxy Watch 5 series will launch in the third quarter of 2022. As per the new sources, Samsung might introduce a skin temperature sensor on the board. As the time comes, we will receive more information about the next smartwatch.
