The problem of modern smartphones is not small capacity of battery. A lot of mobiles have a battery with 3 000 mAh or higher capacity. Unfortunately, modern smartphones with high performance components consume a lot of power. Of course, modern chips are very power efficient, but this efficiency is achieved during normal mode operation.
The problem occurs when a user launches an application or a game which requires a lot of computing power, mobile modem or WiFi module data transmission, GPS localization etc. As you probably know, this is the reason why you should not be guided by the battery life times provided by smartphone manufacturer in the specification.
The real smartphone battery life time depends on the way how you use it.
If you play a lot mobile games, then even the best smartphone will not survive the whole day on a single charging. For these people, fast charging techniques and power banks were designed. Let’s back to the topic. I have found for you two very interesting battery life-time tests. Do you wonder which smartphone have won?
The first test was performed by German department of Samsung.
Samsung has decided to compare the battery life time of their high-end products (i.e. Galaxy S7 and S7 Edge) with competitive smartphones, i.e. Apple iPhone 6s, Huawei P9, HTC 10, LG G5, and Sony Xperia X. Samsung engineers have run the same animation on all smartphones. The mobiles used during the test had the same settings which have an impact on battery life time, i.e. they turn off WiFi, Bluetooth, NFC and removed SIM card. Of course, Samsung smartphones have won this competition.
The second test was performed by TechRadar redaction.
This test is very interesting, because it compares the battery life time when Pokemon Go game is turned on. As you probably know, this game consumes a lot of power, therefore all Pokemon trainers cary a power bank. This time, iPhone 6S Plus, LG G5, HTC 10, Samsung Galaxy S7 Edge, Nexus 6P and the OnePlus 3 smartphones have been compared. Again, the winner is Samsung Galaxy S7 Edge. The second place belongs to iPhone 6s. This is very interesting, because these results are very similar to the test performed by Samsung engineers.
