Samsung Galaxy S10e Dual SIM


A flagship in a smaller format


The battery’s capacity (or the weak system optimization when it comes to the power usage) is the biggest problem with which the users of S10e will have to face. The cell has a 3100 mAh capacity and it ensures average lifespans in an everyday usage. It is confirmed by results achieved with a more detailed measurements:

  • lifespan with the display on (YouTube, 1 SIM card, mobile network, 50% of screen brightness, minimal volume level) – 7 hours and 46 minutes,
  • PC Mark battery test result – 8 hours and 48 minutes,
  • Geekbench result (full discharge) - 3170 points, discharged after 5 hours and 17 minutes,
  • an hour of streaming videos (Chrome, 1 SIM card, active Wi-Fi module, 50% screen brightness) - 9-10% of battery lost,
  • an hour of playing videos from the phones memory (airplane mode, 50% screen brightness) - 6%,
  • half an hour of playing online navigation - 9%,
  • half an hour of playing Real Racing 3 - 10%.

In practice S10e had to be charged either every day or every 1.5 day, using it moderately (without the AOD function). In the more economical mode I managed to achieve two days, but on the other hand I had no problems with discharging the device in one day before the evening.

Charging is not fast, in order to achieve 100% we need to wait around 95-100 minutes. There is wireless charging and reverse inductive charging (Wireless PowerShare) – which in practice means that we can wirelessly charge a band, smartwatch or BT earphones. It works, and even though we might treat it as a not very useful feature, it can in fact be really useful in various situation (like a long weekend with a dedicated smartwatch charger). So if you have any gadgets that can use wireless charging, this function will be useful. We can run it from the notifications bar, after that we just need to turn the smartphone and place a device that we want to charge on it. There is a security measurement which prevents the smartphone from discharging itself – Wireless PowerShare turns off when the battery falls to 30%.


Manufacturers assume that smartphones from the highest shelf will be more popular when they will have bigger displays. While the reviewed model from Samsung is designed for slightly different customers – those that expect great specification, but are looking for a device that can be used with one hand. And this is the case with Galaxy S10e - it is light, compact, it lies in hands perfectly. It is waterproof, with great cameras (though not the best on the market), perfect display, dual SIM support and a high amount of memory. This is an almost perfect device for those looking for an efficient smartphone that can be used with one hand. You might not be entirely pleased with the battery and the slightly too high placed fingerprint scanner. But there are many more advantages than flaws and I think that this is a successful model from Samsung, which will work in all tasks that you will place in front of it.
