Speculating about the Samsung Galaxy S9 battery life details can be difficult – it’s incredibly hard to make accurate predictions about the battery life of a new smartphone for a number of reasons.
Firstly, the Samsung Galaxy S9 may have a number of software optimizations that could help to increase the battery life. Secondly, new hardware may help to change the outcome of the battery life and thirdly, the battery capacity itself may be different to previous flagship smartphones.
Instead of trying to make a guess at what the battery life may be based on what potential hardware and software optimizations may be made, we can instead look back at the last few Galaxy handset releases and compare their battery life and their battery capacity to make an estimate about the Galaxy S9 battery life details. Going all the way back to the Samsung Galaxy S3, we have correlated data to make an estimate about the Galaxy S9 battery.
The data shown in the chart below shows the hours it takes for the battery to run dry during different activities. The score is an aggregative rating of all three activities and marked against the battery capacity.
|Smartphone||Talk time||Web Browsing||Video playback||Battery size||Display||Resolution||Battery efficiency|
With previous battery performances, we can safely say that the battery efficiency of the Galaxy S9 shouldn’t drop below a rating of 30. However, if the Galaxy S9 keeps the same 2K display we could see a rating in the high 40s.
In this case, we could see a talk time of up to 31 hours, web browsing times of up to 14 hours and video playback times of up to 20 hours on a 3,000 mAh battery. On a 3,500mAh battery, the Galaxy S9 could have a talk time of up to 41 hours, web browsing times of up to 18 hours and video playback times of up to 26 hours.
