Stock Charger / EP880 Quick Charge 1.0 / UCH10 Quick Charge 2.0 Test

Hi,

Having talked to people in this thread I decided to perform tests on the M4 chargers to see how fast they really charge. I also got tips learning from the Xperia Legend @Jozinek in his thread here.

I've been buying Sony Ericsson / Sony phones for years. I notice that while the battery size is increasing, the charger output capacity is not, meaning it takes longer to charge each generation (this is generally true for the low/mid-range Sony phones which I've bought. I note that the premium Sony phones get Quick Chargers).

I plan to test 3 chargers, the stock 450, the Quick Charge 1.0 EP880 and maybe the Quick Charge 2.0 UCH10 charger. About the UCH10, Sony says the M4 Aqua is not compatible with it, but according to the Quick Charge Maker Qualcomm, the M4 has a chipset with Quick Charge 2.0 enabled.

Tests are done form 0% battery. I turned on the phone when charging started to view battery levels. I turned off data, turned on aeroplane mode and turned screen brightness to the lowest to minimise interference.

*to be added*

Model EP880 (Fast Charge 1.0)
10 minutes charge - 9%
20 ms - 15%
30 ms - 24%
40 ms - 32%
50 ms - 41%
60 ms - 50%
70 ms - 59%
80 ms - 67%
90 ms - 74%
100 ms - 81%
110 ms - 87%
120 ms - 93%
130 ms - 96%
140 ms - 99%
141 ms - 100%

My notes:

• The average charge every 10 minutes is about 9% battery charge


• The charge per 10 minutes dropped from 9% to about 7% somewhere in the 60s %


• The charge per 10 minutes dropped from 7% to 3% in the 90s %


• The level seems to be exactly in the middle performance wise, higher than the model 450 stock charger and less than the Quick Charge 2.0 UCH10 charger, judging from @Jozinek 's work here.
