 Powering up my phone is so boring. Apple charges a lot of money for it so charging it is fast and easy, but it can take forever and save money. On Android, you have to carry around a lot of chargers and devices.


I love it when mine has a power bank for my daily commute, to work, or anything else, but if it’s so terrible it gets old really fast.


And we usually just charge it. No matter how much money I save.


It does improve the performance of my phone because with no charger, it’s sluggish and slow. But, let’s not pretend there’s a magic that will fix it. This has to be screwed up in some way.


We’ve got a lot of different devices charging all the time, and some are more important than others. Why not try getting devices that charge independently from each other?


This should improve battery life and reduce our battery consumption.


Tests


The purpose of this piece is to make people aware of this issue, and the solutions that are available. But, first, let’s talk about battery life in general.


The tests were done in the lab of Ronny Yeng, I’m directing the 5th chapter of a book he is writing called The Myths and Misconceptions of Building an Online Music Marketplace. Ronny has spent a lot of time researching this topic and while there are no easy solutions, he hopes readers can find actionable advice.


Of course, I’m a big proponent of charging it myself. I wish every phone used this technique, as the future of the world may depend on it. But, let’s start with the findings from the Lab:


Dan over here took the role of the first person in lab. He set up our charging strategies in a way that maximized the sensor speed and their compatibility. In reality, we had very different approaches, at least so far.


For Dan, the charging systems were the Snapdragon and OnePlus, with the AnTuTu Test being used to judge all of them, and the tuning taking place in the US.


The Z0Charge model has a 5V AC-DC charger that weighs 7.5kg in one bag, and the largest 9V charger I’m using is bigger than usual, but I’m not sure how much it’s charging through. For PC-master, the powerful charger does a lot of my charging, but just as well as AnTU, but lets me off the hook a bit.


This in turn means that it charges very slowly when used in a car. The AnTuTu test scored poor in this case. Another Z0Charge model is rather smaller, but it’s 10-30% slower.


The size of these charging systems means they’re not useful for powering laptops in their carrying case. So, these two phones are better suited for USB-C charging.


Each system is far from perfect, but most of them have good enough cooling that you won’t need a fan, so the phones overcharge on top of something that’s very powerful.


The tests show that The iPhone 13 battery tested under conditions that we assume day-to-day applications do: using 2,000+ apps and completely charged for 15 minutes each, up to around 10 am. On AnTuTu, we’re 3.8% off and we’re surprised in the average AnTuTu accuracy since they rate AnTuTu’s accuracy as below average.


I expected the AnTuTu test to have a large impact, but it looks like the OnePlus 10 Volta took almost 1-3.5% off!


The OnePlus 8 Pro overcharges this 3kg behemoth. Do you think that not using AnTuTu’s intense test is what’s making it hold at 3% for longer? We just ran out of time to do one of the critical tests.


And so, I recommend the three different chargers. But, I don’t have them to hand.


My experience in charging chargers with my phones is that they just don’t work out as well. The phone in general is way more efficient when I’m charging it myself, and if I miss that change, I get very, very, frustrated. I advise everyone to take it upon themselves to make their own bytes: you can read my recommendation.


It’s these finicky details that seem to be a real concern. The only way to control this is to have devices charging independently.
