I have a Samsung Galaxy A53 and the battery doesn't last the whole day. I was looking at fast chargers at Fnac but there are so many brands and different wattages that I don't know what to choose. Does anyone know which one is reliable and won't damage the battery?
I get that concern because we all want our phone to last, right. But I'm gonna be honest with you: I've already charged my phone with every fast charger out there in my life as a delivery driver and what really damages the battery is keeping it always at 100% or letting it completely die, not so much the charger itself. That said, for your Galaxy A53 you don't need anything super powerful - Samsung actually recommends up to 25W. Samsung sells their own chargers which are reliable, but third-party brands like Baseus, Anker or even Motorola work fine too. What matters is you don't grab those super generic chargers from random sellers on the marketplace, you know? The ones that cost like 5 bucks. Check if it has safety certification, if the brand has good ratings.
At Fnac you're good because they're kind of picky about what they sell, so pretty much anything they have is gonna be fine. If you have the option of 20W or 25W, doesn't matter - your phone will charge fast either way. Now, some practical tips: don't leave the charger plugged in the outlet 24/7, because that heats it up and can damage the battery in the long run. And if you want your battery to last more throughout the day, try charging up to 80% when you're gonna use it a lot, instead of always filling it up to 100%. I do that with my phone and it does make a difference. Also, if your Galaxy A53 is not holding a charge as well, it could be that the battery is getting old and maybe it's worth replacing it later on.
I understand the confusion because there's really a lot of stuff on the market 😅 First, check what's the maximum power your Galaxy A53 supports - basically that model handles up to 25W of fast charging, so there's no reason to spend more money on a 65W or 100W charger because your phone won't actually take advantage of it anyway. The thing is, after a certain wattage, the phone is smart and regulates the current, so you're just paying more for the packaging.
As for brands, I'd say go with Anker, Baseus or even original Samsung chargers if you find a good price - these brands have quality protections and certifications that actually matter. Fnac also sells decent Portuguese brands like Nuvem or even some generic ones that work fine, but always check if they have CE certification and make sure they're sold by sellers with good ratings. The important thing is to avoid completely weird brands that cost 3 euros because that's when you could have problems 😬
To not ruin your battery, avoid leaving your phone charging overnight - what really damages it is being near 100% for hours. A reliable 25W charger is enough and it's still fast. I've been using Anker for years on my stuff and never had any issues, honestly I'd recommend starting there if you find one at a good price!
Oh man, I'm gonna speak from experience here. I also have a Galaxy A53 and bought an Anker 25W charger at Fnac - that must be like two years ago now and it's working perfectly, battery's still doing great. It's exactly what the guy said: don't go beyond 25W because it doesn't help, the phone won't even use it. I personally avoided those really sketchy Chinese brands you see from street vendors, because in my plumbing job I've seen people burn out their chargers and damage their phone's charging port. Anker, Belkin and original Samsung are super reliable, and you can find those easily at Fnac. Oh, and a tip: let your phone breathe while it's charging, like don't use it while it's charging, it really helps with battery health.
What they said above is true - the A53 handles 25W and there's no reason to go beyond that, you're just wasting money. I had the same problem myself with the battery dying around 4 in the afternoon, and switching to a 25W original Samsung charger (grabbed it at Fnac) made quite a difference. What really matters is getting something with certification, like original Samsung, Anker or Belkin - these brands have overcharging protection, so the battery stays in good shape. Pro tip: avoid those weird bazaar brands that cost €2, because then yeah, that's when you actually ruin the battery or worse, set your phone on fire 🙃
Basically the A53 can handle up to 25W, so you don't need to go beyond that - anything more powerful won't charge faster anyway. I'd say look for well-known brands like Anker, Belkin or Samsung itself because they're reliable and have warranty, and avoid those super cheap random brands from AliExpress that nobody knows. What matters is that the charger has certification (look for "certified" or "original") and it's not high wattage that damages the battery, it's mainly keeping your phone constantly at 100% - so charge up to around 80-90% if you can and it already makes a difference. I'm always charging mine during stops on the road and I'm more careful about this, and honestly a decent brand fast charger lasts years without problems.
