Hi, this is Wayne again with a topic “What’s REALLY killing your smartphone battery?”.
This video is brought to you by Android authorities. Tech deals, Walter, no contact a way to disinfect surfaces without liquid stay tuned for more details. Battery life is arguably one of the most important things to look for when purchasing a new smartphone, and while a lot of us give the screen on time. Metric in reviews, what’s typically found on the spec sheet, is often a four figure number suffix by the acronym m8h or milliampere hour, and that indicates how big the battery is in your smartphone. But what happens when a device with a smaller battery beats out a device with a bigger battery in battery life? Let’S find out before we dive any deeper into battery life, we need to define what a milliamp hour is, strictly speaking, it’s a unit of electric charge which is equal to supplying one milli amp of current constantly for one hour, so one milliamp hour battery can provide One milliamp of current for one hour and a 1,000 milliamp hour battery can provide one milliamp for 1,000 hours. However, if the current doubles to two milliamps, a one thousand milliamp hour battery can only provide to that two milliamps for 500 hours. It’S quite simple math.
Of course, in the real world, smartphone batteries don’t tend to last a thousand hours, because the current being drawn is often much more than one or two milliamps. Given a perfect testing scenario, where all smart phones draw the same amount of current, a larger battery is simply going to mean longer battery life, but in reality this is pretty much never the case as different hardware and software inside phones can and will pull more or Less power, so it makes it hard to determine battery life, given just the milliamp hour number. It’S properly showcase this. My wonderful colleague Robert tricks, ran a number of tests in which the subjects looped speed tests G.
This is a performance benchmark which really pushes the phone. The results are presented in a number of hours that the phone lasted before shutting off due to running out of juice. The selection of smartphones ranged from a pixel four, with a twenty eight hundred million power battery right up to the rock phone, which has a massive six thousand milliamp hour battery. But what you’ll notice is that there isn’t a strong trend shown in the results.
Despite the massive range of battery sizes tested in exactly the same conditions with regards to brightness and wireless connections, etc, weirdly enough, it’s the three thousand seven hundred million power, pixel 3a XL that wins the test and not by an insignificant margin at all. It stumped. Even the massive six thousand milliamp power, rock phone and you’ll notice that, even though the pixel for Excel has the same 3700 and power battery, the three XL handily beat out the pixel for Excel and our data doesn’t show a trend because there really wasn’t one. So it’s obvious at this point that the hardware and software configurations make a massive difference in how long your battery is going to last. But what’s really going on well find out after this message from today’s sponsor concerned about germs or viruses who isn’t these days? Blasting, your body with UV light might not be the best solution to viral treatment, but it’s actually a great preventative way to keep the devices use every day clean and hygienic. With the mini UV light bar, you can disinfect anything with the touch of a button.
It’S great for keyboards phones, computer mice, anything that you probably wouldn’t want to wash with soap or water, since the mini UV light bar is possible. It’S also great for elevator buttons and trips to public restrooms. Any surface you want to be disinfected can be done in seconds. Normally the mini UV light bars run for $ 100, but today you can snag it from tech.

Out of the way, you need to understand that the battery in your phone is powering everything on and in the device. So that’s the notification LED the pop-up camera the screen, the speaker, the processor, Bluetooth connections, everything. So if a phone has more physical features that use up more power like motion, sense or always on displays, then they’re going to impact battery life and the same goes for mid-range versus high-end processes.
Sure, a Snapdragon 700 series chip isn’t going to give you the pure grunt and the horsepower that an 800 series chip would do, but, on the contrary, it uses far less power. What that trade-off is meant in the past is that you kind of had to pick the high-end chip. If you wanted to play games more recently, that performance margin has got very close and I feel like you could easily pick up a mid-range 700 chip set and get good gaming performance. But, of course, you’re using less power.
High refresh rate displays are another in thing. At the moment, but there’s a reason why Samsung ships their 120 Hertz capable s20 series at just 60 Hertz. The increase in current usage, when using high refresh rate displays, is insane the 43 hundred million power 1 8, with the 90s display, for example, it gets better battery life in our testing than the 120 Hertz want, plus 8 Pro, with its larger 4510 million power battery.
Otherwise, the specs are pretty much identical, and so you can really pinpoint the refresh rate of the screen as being that point of failure. Software is also a massive factor. Just look out how consistently great Huawei’s devices have been for battery life. Sure they’ve got bigger batteries, but what they’ve also got a software that kills apps when not in use, sometimes to the detriment of the user experience, and the same goes for Oppo and shiny.
More of a recent issue in terms of battery life. Is that a 5g? Not that 5g is bad or anything, but it uses a lot more power. At least the 5g modems do than their 4G counterparts, meaning that, if you’re constantly connected to 5g you’re going to experience significantly worse battery life than if you were say connected to Wi-Fi and what further complicates matters is that there are tons of different 5g modems. That use all different power levels, so it’s hard to pinpoint which devices are going to give you better battery life. So what can we take away from this? Well that when looking for a smartphone with good battery life, you cannot simply rely on that for figure metric to get a good idea of how good the battery life on that phone is. Look at the components being used. The refresh rate of the display, the always running, features and the software loaded up. Of course, if a phone is using a power-hungry 5g modem, that’s going to be a factor. I know it sucks that we don’t have a universal way of showing how good a smartphone is and for various reasons, the screen on time.
Metric isn’t necessarily all that reliable either. But until we have a test that we can run on every single phone in every single condition, it’s just going to be a matter of doing your due diligence to get a device with the right battery life for you and that about rounds out today’s video guys. Thank you all so much for watching. I will leave Robert Triggs as article version of this in the the link in the video description, so you can check that out.
I do highly recommend you check it out. It’S a good, read and yeah thanks for watching. Please do subscribe like and comment to.
