Samsung Galaxy Tab S7 Plus Performance
Samsung Galaxy Tab S7 Plus : Battery Life
The Samsung Galaxy Tab S7 Plus has a massive 10,090 mAh battery, which promises to deliver up to 14 hours of video playback time.
To test its battery life, we turned off Automatic Brightness, and set its display brightness to 50%.
Why 50%? That is actually slightly higher than the average indoor brightness level of 40% during the day, and is what we usually use in all our mobile battery life tests.
It is important to fix the brightness level, to make sure the screen brightness does not change as the room brightness changed.
We then ran the PCMark Work 2.0 battery life test until its battery capacity dropped to 20%, repeating several times.
These are the best results we obtained at the standard 60 Hz refresh rate, and the dynamic refresh rate of up to 120 Hz.
Just under 8 hours. Well, that’s far from the rated 14 hours… even with a 60 Hz refresh rate.
It gets worse if you turn on the dynamic refresh rate that automatically adjusts the refresh rate from 11 Hz to 120 Hz – it lasted just over 6 hours!
Samsung Galaxy Tab S7 Plus : Recharging Speed
The Samsung Galaxy Tab S7 Plus supports the phenomenally-fast 45 watt super fast charging. Unfortunately, Samsung only bundles an anaemic 15 watt fast charger in the box…
Take a look at how fast its bundled 15 watt fast charger topped up its massive 10,090 mAh battery…
Not bad. The bundled 15 watt charger took just 2 hours 26 minutes to fully recharge its battery from 20% to 100%.
That gives it a recharging speed of about 55 mAh per minute, which is actually faster than some 25W or 27W fast chargers.
Even so, it cannot make up for the poor battery life, with a poor battery life : recharging ratio of 2.5:1. A general rule of thumb – for one of hour battery life, you just need to charge it for 23 minutes.
Just to give you an idea of how bad that is – the HUAWEI MatePad Pro has a battery life : recharging ratio of 8.5:1, and only needs 7 minutes of charging for each hour of battery life.
