Let me tell you a short horror story. You need to charge your phone but the charger is available in the vicinity only for a short period of time. Thereby, we list some of the ways to charge your phone faster.
Let your phone fly by putting it into Airplane mode. Okay, sorry for the exaggeration. Airplane mode turns off battery draining services. Granted, your phone will be out of reach to your callers for that period of time, but you know that’s why we’ve call diverts. Our extensive testing showed a noticeable improvement in charging time with Airplane mode turned on. You could always go a step further and completely switch off the phone and then charge for even improved charging times.
The right charger
When you want to charge quickly, it’s recommended to charge your device through a wall outlet rather than charging through USB port from the laptop. But not all chargers are created equal. The charger which came with your phone may or may not be the fastest charger for your device. To verify, first check the output current rating on your charger. A 2A charger would charge your device faster than the charger with 1A. (Remember, 1A= 1000mA)
You may try different charger with higher output current to charge your phone faster. But it’s only a part of the story.
Your device also needs to accept the higher output current. There’s no use if you are using a higher current charger but your device is not accepting it. To verify, I suggest you download Elixir and check your battery current in the device menu of Elixir.
USB Cable matters
A couple of days ago, I misplaced my Xperia Z2’s USB Charging cable and got a cheap USB Cable. Even after plugging it for more than 3 hours, my battery had charged a meager 32%. It was charging incredibly slowly.
I did some research to find out that Xperia Z2 stock charger came with wire gauges of 28/24AWG while the cheap USB cable I was using was of 28/28AWG. A 28/24AWG is 60% larger and can handle current up to 2A while the other one can barely handle 0.5A.
So, to suffice it is safe to say that your phone can charge faster if you are using a wire gauge of 28/24AWG rather than a 28/28AWG one.
Unfortunately, there’s no easy to determine what’s the wire gauge of your cable as they look same on the outside. So, make sure you read the specifications while buying one over at Amazon or Flipkart.
Experimenting with different Kernels
A kernel is the central unit of your device’s software. It manages how much CPU time and memory has to be allocated to an application. It isn’t wrong to think of Kernel as the heart of your devices which decides how applications will run on your device.
Sometimes, a phone’s circuits are able to accept higher current but due to various reasons, manufacturer can decide to not utilize the full potential and clock down the acceptable current. If you are rooted on your Android, you can try experimenting with different kernels and see whether you can benefit from higher charging current. We shall soon do a detailed write-up on how to change kernels on your Android. Stay tuned!
Utilize in-house quick charging techniques
Various manufacturers are developing their own quick charging techniques to refill your battery faster. For instance, all Qualcomm Snapdragon 8xx series processors support a quick charge functionality. If you’ve a supported device, you can usually find an option in your settings menu. Popular devices include Galaxy S5, Note 4, Nexus 6, LG G3, OnePlus One. While the Xperia Z2/Z3 potentially supports Qualcomm Quick Charge 2.0, Sony has decided not to implement it for unknown reasons. You may want to check its implementation with your manufacturer.
So there you’ve it. You can use a combination of the above tricks to help your phone charge faster. If you’ve some other tips for our fellow readers or need some assistance tweaking your phone, do sound off in the comments.
