[Samsung Galaxy M51 Real Life Review] cacadooo:
Hi guys. I wanted to let you know my findings and provide some test results of galaxy m51 battery life. Firstly, I will outline what was my priority for that test. I wanted to check how long the phone can last mainly on google maps navigation with additional apps in the background. Also this test is a bit static so to speak but had no chance travelling for so many hours. That said I believe SOT was tested correctly for my planned usage. I guess in a real case scenario, I would need to do some more browsing and perhaps occasional screen switch offs during a break like filling up the fuel or stop to rest on a bicycle.

How I performed my test.

1.	I did some initial installations, downloaded my apps and logged in to social apps such as FB, Spotify so they can work in the background, send notifications etc.

2.	Once I completed the setup, I charged the very new phone to 100%. AccuBatter reported capacity was 6800mAh designed capacity not 7000mAh and estimated capacity 6700mAh.

3.	CPU-Z reported Snapdragon 730 so I regret it is not 730G and honestly I do not know how to check with online stores as the packaging does not help with this. Also, I plan to test POCO F2 PRO 8gb ram/256gb version the same way and see how it goes since I get better hardware, but I like SD card slot on galaxy m51. Very useful when resetting the phone.

4.	Set google maps navigation, lunched another app which uses GPS and LTE for maps showing speed cameras, road works or dangers which I use alongside with google maps. I also start shuffle play on Spotify to imitate streaming the music in my car or on the bike.

5.	WiFi, LTE, GPS, Bluetooth, sync was enabled, blue light filter enabled.

6.	Between 15-20 apps were in the background.

7.	I unplugged the device from the mains.

8.	Initial 15% discharge was with a WiFi connection with my router. Then switched of my router for overnight, left wifi enabled on Samsung but it had to continue downloading data over LTE such as Spotify music streaming. I also changed google map setting to day light only to avoid night backlight.

9.	I went to bed? and in the morning there was still a lot of juice.

10.	Around 20% discharge I took about 100 pictures most of them in burst mode to simulate a trip where you simply stop and take some snaps.

11.	I stopped the test at 1% discharge and noticed no heating problem. The phone was cool during the test.

The overall SOT measured until 1% discharge was a staggering 17h 50m? Below you will find AccuBattery screenshots. At remaining 15% I had still over 2 h 42 m of use left.

This phone reminded me of good, old days of my Samsung galaxy s3 with a Zerolemon 7000mAh?

Now with my galaxy s7 deteriorating battery (current capacity just over 2300mAh) this is a great thing. For Galaxy s7 I also own a KiwiBird powerbank case of 5400mAh right from the beginning wich did its job when away from the mains, travelling etc.

I guess for a more accurate SOT, I would need to add some phone calls and browsing but even with I deduct 2h, it is still nearly 16 h of use. Like for me excellent. I also do not plan gaming.

On the downside of this phone it seems like my galaxy s7 takes a bit better picture, but it just might be my perception of selfies taken. Back camera is also just ok on a cloudy day. Ok but that is an offtopic.
