Which android phone is the fastest

Fastest Android smartphone: we test 2016’s most powerful devices

In our overview of the fastest Android smartphones, three devices are emerging in the new categories. Here you can find out which smartphones are the best for gaming, for photo processing and the best for everyday usage.

Google Pixel: fastest gaming performance

The Google Pixel was not developed with gamers in mind, and it was not promoted as a device for gaming. That said, when we did the comparison we found that the 3D performance on the Pixel was the fastest. As a result, and also thanks to the Daydream optimizations, the Google Pixel is super for VR applications.

We tested these devices three time, after which we calculated the mean value.

Samsung Galaxy S7 and S7 Edge: fastest image processing

Samsung developed its own processors in 2016 and both the Galaxy S7 and S7 Edge are fully optimized. Both devices have the same chip: The Exynos 8890. This delivers high scores on Geekbench, and effectively hangs its younger competitors out to dry.

The image processing performance on the device is excellent. Compared with the rest of the smartphones on the market, camera for the Galaxy S7 and Galaxy S7 Edge is one of the best. It has a quick release mechanism, and the snapshots are sharp and good contrasting for almost all light conditions. The processor also ensures you get fast post-processing or effect preview in real-time.

Huawei Mate 9: fastest for everyday use

The Mate 9 is one of Huawei’s best devices and includes the latest high-end components. Although the device hasn’t been released in the US yet (it’s expected to be available in early 2017) when it does hit the market we’re expecting it will be much cheaper than most of its competitors.

We weren’t surprised when we saw high score ​the Mate 9 managed to get for the storage performance from PC Mark for Android. However, we had already experienced this first hand during our review, so even before we had the final figures ​​we were already sure it was a strong performer.

Whether it’s powering up, awakening from standby via fingerprint, or installing or launching apps, you never really have to wait for the Mate 9 to swing into action. Once you’ve got used to your workspace, other smartphones are sluggish. The key: Huawei uses an intelligent offline algorithm, which adjusts to your usage behavior and maintains the high speed of the smartphone in the long term.

Which Android phones charge the fastest?

Update: After speaking directly with Oppo it seems that the USB dongle we were using to measure the current and voltage was interfering with the VOOC quick charger system, as it uses a special 7-pin cable and the charging will only work when using that cable directly connected to the charger. So we re-ran the tests and updated the article.

There is no getting away from it (not yet), every mobile device needs to be charged up. That is because they all have batteries, rechargeable batteries that give us a certain number of hours of use and then these useful battery cells needs to be replenished. It is something you probably do every day, almost unconsciously. You plug in your phone and let it charge, while you get on with other things. So since it is something that we all do daily, it would be good to know which phones charge the quickest!

The Tests

Before we dive into the results of our testing, let’s have a quick look a the charging cycle for Li-ion batteries and see how we tested the charging of each phone. The charging cycle for a smartphone battery is performed in two stages. This is true for standard wired charging, for quick charging and for wireless charging. During the first stage a constant current is applied to the battery. Then when the battery is around 70% to 80% full (depending on the exact battery design) the current will be lowered but the voltage will remain the same. This means that the phone will always charge faster from 0% to 80% and then slower for the last 20%.

As well as measuring the total charge time, I also measure the current and voltage levels drawn by the phone from the charger. To do this I used an inline USB volt and amp meter (pictured below). At regular intervals I noted down the time, the battery level, the voltage reading and the current level.

The Phones

For a our testing we picked a variety of phones with the aim of covering some of the top flagship devices of 2015, plus some which offer various quick charging technologies. The list in alphabetical order is:

And here is a graph of the battery sizes in mAh:

The Oppo R5 has the smallest battery, while the Moto X Force has the largest. It is also worth noting that the median battery size is 3000 mAh as found in the Note 5, the LG G4 and the Moto X Style, to name a few.

Power Curves

So batteries provide electrical power to our smartphones and to replenish those batteries they need to be re-charged, power needs to be put back into storage. To do that you connect your phone to a charger, normally the one that came with the phone. The charger has two characteristics which define how much power it can provide to the battery, the output voltage and the output current. The level of electrical power being pushed into the battery is measured in watts, and watts is calculated by multiplying the volts and the current.

To charge the phone quicker you need more watts, more watts means either more voltage, more current, or more of both. A standard USB 2.0 port provides 5V at 0.5A, so that is 2.5 watts. A modern fast charger is rated at 5V and 2A, which is 10 watts. A quick charge system, like Qualcomm’s Quick Charge 2.0 (QC 2.0), is rated at 9V or 12V and at 2A or 3A. Typically a QC 2.0 phone will charge at 9V and 1.5A, which is 13.5 watts, but there are those which go as high as 9V at 2.2A, almost 20 watts. Qualcomm has also announced Quick Charge 3.0.

For those interested in the technical bits, it is interesting to see how the phone charge. Here is a graph of the watts and battery level over time for the Huawei Mate S:

As you can see the battery is charged at 7.5 watts (5.1V, 1.46A) for over 90 minutes, then when the battery gets to around 80% full the watts decrease slowly until the battery reaches 100%. What is also interesting is that the battery is charged to 80% in about 65% of the total charge time, but to bring the battery up from 80% to 100%, takes another 45 minutes. This is of course because the wattage is lessening over time as the battery reaches 100%.

For phones which support Quick Charge 2.0 (or a variation of it) the initial wattage being pumped into the battery is much higher as the voltage used is around 9V and not 5V. Here is the charging graph for the HTC One (M9):

As you can see the initial power level is 12 watts, 4.5 watts more than the Mate S. This level is maintained for 40 minutes when it then drops slightly to 10 watts until the phone reaches 70%, then the power drops steadily as the battery level approaches 100%.

The phone with the most interesting charging cycle is the Moto X Force. It starts charging with 8.97V at 2.23A, which is 20 watts:

Once the battery reaches around 65% the current level starts to drop, however even at its lowest level, it is still consuming over 5 watts. The result, as we will see in a moment, is a very fast charge time.

Here are some graphs for a few of the other phones in our test group:

Update: New graphs added showing the real charging times of the Oppo R5 and Oppo R7 when using VOOC.

Sony Z5 Premium

Fastest

So which phone charges the fastest? Is it a phone with a small battery like the Oppo R5 or the Huawei Mate S? Or is it a phone that pumps the most watts into the battery? Let’s see:

Update: New charging times for Oppo R5 and R7: The Oppo R5 charges in 75 minutes and the R7 in 77 minutes.

So, the top five fastest charging phones are the Moto X Force, the Oppo R5, the Oppo R7, the Moto X Style and the LG V10. The slowest three are the Huawei Mate S, the Sony Xperia Z5 and the BlackBerry Priv.

The Moto X Force is really a surprise winner in that it has the biggest battery, so you might have thought that it would take the longest to charge, but because it uses at to 20 watts of power during the initial stages of the charge cycle, it is able to beat all the other devices including those using QC 2.0 at 9V and 1.5A, and those with smaller batteries.

Since we know the battery sizes and we know how long it takes to charge it phone, we can also see which phone increases the battery level the most in one minute:

Update: New data for Oppo R5 and R7.

The Moto X Force is again the winner, followed by the Moto X Style and the LG V10, however further down the list we can see some changes. For example, the BlackBerry Priv takes the longest to charge its battery, in actual minutes, however it is charging faster than the Sony Xperia Z5 and the Huawei Mate S.

As for the Oppo R5, Oppo has a quick charging system called VOOC which is meant to operate at 5V and 4A (i.e. 20 watts). However we couldn’t get the R5 to use those levels in our testing, even when using a VOOC charger. And that is a shame, as it would have been interesting to see the charge time of the 2000 mAh battery of the R5, if it was charged at 20 watts!

Wrap-up

So the clear winner of is the Moto X Force. It has a big battery and a powerful charging cycle. It really is ahead of the field. Oppo does well with its VOOC fast charging system, however the total charge times for the R5 and R7 are also lower because of the smaller battery sizes. In terms of charging rate the Moto X Style performs well and comes in second to the Moto X Force.

LG makes a good showing with all three of its phones in our group appearing in the top 8, including the LG G3. The Galaxy Note 5 also does well taking 4th place in terms of charging rate. Unfortunately the two Sony phones don’t do that well and neither does the BlackBerry.

Now we know how long these phones take to charge, but how long can the battery last? We have tested six of the best flagship devices for our Best of Android 2015 series, so why not head over to this post to see the results!

So, what do you think, does the charging time of a phone altering your buying decision? Is it an important factor for you? Please let me know in the comments below.
