The 2900mAh with Mumbi battery has now come to full capacity after about 7 to 9 complete charges. I mention this explicitly because I hear often that the third-party batteries usually are only deceptive anyway.
Namely, too often expected that the battery needs to provide at least nearly 11.5% more after the first store, so now instead of 8 hours of intensive use 9 must be possible!
To get there, you have to give the battery the same time had the home supplied by battery even earlier. So the 7 to 9 complete charge cycles.
Moreover, hardly a user will carry out standardized term measurements are then also meaningful.
But I myself have noticed an even more important for me behavior.
The original battery behaves so that from 20% residual value necessarily at the earliest opportunity an outlet must be consulted because the discharge behavior from then behaves in anything but linear.
At Mumbi battery is significantly better for the targeted charging cycles.
Even with only 7% indicated I know that the phone will not suddenly shuts down and I can still carry on a conversation to end in peace.
Chill the Mumbi battery behaves with 5% as the original battery with 20%.
That's good! Finally a reliable indicator, after I can judge me.
I tried to be observed almost same conditions from 20%.
And I turned to my amazement found that from holding as at Mumbi battery not about 11% longer, but this holds at least in this area of the power output more than twice as long as the original battery my device up to forced shutdown alive ,
For me, it actually means that I am totally relaxed at 30% capacity in the afternoon and continued the phone, listen to music and surf the Internet.
Only in the evening I can now completely relaxed, charge it overnight.
In most cases this is in my usage behavior anything in the range between 9% and 16%.
For me, a strong buy recommendation!
