So 15 days after replacing my Galaxy S6 original battery with S7 Edge one, I have gathered some stats, that might give you an idea just how much improvement you can expect.

So I am using GSam Battery Monitor to track my battery life.

Just for some context – here is a screenshot from just before I did the mod:

You can see that the averages per complete charge show a very degraded battery – just bellow 17 hours on average with just 1h 38m of SOT.

After I put the S7 Edge battery, the first day, my phone died just after 30h of usage:

This was a busy day, so only 2h48m SOT, however about 4 hours of Spotify listening over bluetooth.

After the holidays came, I began using the phone very heavily, so my averages became very different.

Here I have some heavy Christmas redditing and browsing.

After New Years’ Eve, although my averages were much lower, because of heavy usage and frequent charging, I am very confident that the battery is calibrated and performing as expected. Here is a day with about 1 hour of navigation, almost 4 hours of Spotify streaming over Bluetooth, a little bit of Reddit and Facebook + half an hour of calls.

 

So in conclusion – I am really happy with my battery life now – we are all looking forward to the graphene battery breakthrough, that will bring  10000 mAh to smartphones, but until then – I am sticking with my Galaxy S6. 🙂

EDIT 18.06.2017: After a little bit over half an year, I am using my phone heavier than ever and haven’t noticed any substantial degradation in the battery life.

My Averages Per Complete Charge are very low, but that’s expected since I am using my phone with it’s screen constantly turned on during the day, sitting at wireless charger, streaming Spotify over bluetooth.
