Yesterday, HTC just announced their new smartphone : HTC ONE A9.
You can read a the full spec from their official site. but as a famous cell phone accessories brand, we will talk something else.
HTC ONE A9 should be the very early device which use powerful 64-bit capable Snapdragon 617 processor with X8 LTE, the smartphone is designed to let its users indulge in cutting-edge imaging.
Snapdragon 617 is engineered for maximum battery efficiency: the HTC One A9 allows viewing up to 12 hours of HD video on one charge. Even if your battery is low, the One A9 supports Qualcomm Quick Charge 2.0 fast charging technology, designed to charge the phone up to 75 percent faster than conventional chargers, ensuring that you’re up and running and not tethered to an outlet. And support for the next generation Quick Charge 3.0 is expected in the coming months.
On HTC official site, it said: Capacity: 2150 mAh with Quick Charge 2.0 support (forward compatible with Quick Charge 3.0 with future software upgrade)
So HTC ONE A9 should be the first device which announce to support newest Quick Charge 3.0. but for some reason, the early version just coming with QC2.0 support, but a future software update will bring the QC3.0.
Our product expert make some analysis according the current information, the information might be wrong, it’s just for reference:
The battery of HTC ONE A9 is 2150mAH, and in order to make the device slim, HTC should still choose Lithium polymer battery and 4.35V amhigh density battery core.
According to Androidcentral preview , the HTC ONE A9 won’t include the quick charger in the package, they just give you regular 5V/1.5A charger, and you need to buy QC2.0 or QC3.0 chargers.
and their official site, there is only one HTC Rapid charger 2.0 for sale. The specification is:
Output:Max 15 watts (5V/1.67A, 9V/1.67A, 12V/1.25A)
From this information, we think the HTC one A9 should do some limited in the input current to 1.5A MAX.( means even you use a 2A charger, ONE A9 just can accept 1.5A max)
So now we can do some calculate:
If you use the regular 5V/1.5A charger,consider the trickle purling, the total charging time should be around 2 hours.
If you use their rapid charger, it is 9V/1.67A, still consider consider the trickle purling, the total charging time should be around 1 hours 10mins to 1 hours 20mins.
and if you use the QC3.0 quick charger, according to Qualcomm description(27% faster than quick charge 2.0) , the total charging time is around 50mins to 1 hour.
We get those result from the current information,but the real charging performance , we should wait for the device coming,and do some more test, We will update this result then.
But anyway, the qualcomm quick charge technology really help to reduce the charging time, especially when your battery is empty, in the first 10-30 mins, those quick chargers can save your time, charge your battery fast!
For HTC, we don’t know whey they don’t release the HTC ONE A9 with QC3.0 directly, but need customer to wait for the firmware update. maybe their QC3.0 charger is not ready?
For us, Tronsmart has been ready for the next-generation charging revolution, We have released the QC3.0 charger last month, see the detail here:
and we will release more and more wall charger, and car charger which equip with the new QC3.0 technology soon.
Consider the high price on HTC rapid charging, and low output ( 15W VS ours 18W), our Tronsmart Quick Charger is your best alternate chargers!
Thanks for the review !
