Samsung Galaxy Tab S7 FE : Battery Life
The Samsung Galaxy Tab S7 FE has a massive 10,090 mAh battery, which promises to deliver up to 13 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 3.0 battery life test until its battery capacity dropped to 20%, repeating several times.
Will you look at that – 12.5 hours of battery life! A little shy of the rated 13 hours, but still much longer than the 8 hours we got with the Galaxy Tab S7+!
With such a long battery life, you can confidently take it on-the-go for a full day’s work without worrying about charging it.
Samsung Galaxy Tab S7 FE : Battery Recharging Speed
The Samsung Galaxy Tab S7 FE 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 36 minutes to fully recharge its battery from 20% to 100%.
That gives it a recharging speed of about 52 mAh per minute, which is as fast as some 25W or 27W fast chargers.
This gives it a battery life : recharging ratio of just 4.8:1. A general rule of thumb – for one of hour battery life, you will need to charge it for 12.5 minutes.
While that is TWICE as fast as the Galaxy Tab S7+, it cannot match the HUAWEI MatePad Pro, which has a battery life : recharging ratio of 8.5:1, and only needs 7 minutes of charging for each hour of battery life.
