Recently, I have always seen people say that it is more cost-effective to change the battery of a mobile phone, but as a person who has dropped his mobile phone into the toilet twice, I have to say that this thing is really not as good as I thought. Especially now that everyone's mobile phones are waterproof, changing the battery casually may dig a big hole for yourself.

Let's talk about how important waterproofing is. Who doesn't keep their phone in their hands now? Take a show, order takeout on a rainy day, take pictures by the pool... Last year, my friend's mobile phone was fished out of the hot pot and can still be used, all supported by the waterproof function. Now Apple has been spill-proof since the iPhone 7, which is a life-saving feature at a critical moment!

But changing the battery is simply "disemboweling" the phone. The manufacturer originally used all kinds of sealants and waterproof rings to wrap the mobile phone tightly, and as soon as the maintenance master dismantled the machine, these protections were all wasted like a "sting" like a dismantling express. My colleague changed the battery last month, and now he is panicking when he washes his hands and splashes some water like defusing a bomb because the repair shop hasn't restored the waterproofing layer at all.

When it comes to repair shops, it's even worse. It's cheap to change batteries on the side of the road, but do you know what glue they use? I once saw the master glue the back cover with 502 glue, and I was shocked! This kind of work is not to mention waterproof, and it is lucky that the mobile phone can be spelled back completely. What's even worse is that there is no one to be responsible for the problem, and in the end you have to pay for the motherboard yourself.

Besides, now mobile phone updates are like dumplings. The flagship machine I just bought last year has become an Internet celebrity this year. Changing the battery can continue life, but the lens is pasted into a mosaic, and the game card is a PPT, isn't this like changing the tires of a classic car? The battery life is good, but other problems still drive you crazy.

In fact, now that fast charging technology is so developed, it is much more reliable for me to go out and bring a power bank than to change the battery. If you really want to change, you have to go to the official after-sales service, although it is more expensive, but at least it is guaranteed. But to be honest, it's time to retire after two years of using the mobile phone, instead of tossing and changing the battery, it is better to directly change the new phone to experience the latest black technology, do you say this is the reason?

At the end of the day, a mobile phone is a consumable. Instead of worrying about whether to change the battery, it is better to use it well and change it when it is time to change it. Remember, the waterproof function is like an airbag for your phone, so don't scrap it for hundreds of dollars!
