The ultimate guide to replacing your smartphone battery

Unlocks your smartphone battery in just a few hours? If you are reaching the charger several times a day, it may be time to replace the battery. Even with the days of mobile batteries behind us, there are still many options. In this manual, we will show you how and how much it costs to install a new battery on your phone.

If you have owned your smartphone for more than two years, you may have noticed that the battery life is not the same. The life of a battery is typically defined by how many charge cycles it should last. A charging cycle is a period in which the battery is fully utilized, then it is fully charged (companies like Apple define it as 50 percent, then recharge fully and then use 50 percent again). After 500 charge cycles, most lithium-ion batteries begin to deteriorate, regardless of how you use the device. It is one of the main reasons why you should consider changing the battery of an aging device.

Common signs you need to replace your smartphone battery

Of course, the most obvious sign you may need is a battery battery replacement is drastically reduced battery life. If your phone barely makes it past the 10-hour mark, and you don't do anything too intense as playing or playing games, consider replacing.

Random shutdowns are also a common symptom. If your smartphone shuts down by 30 percent or even 50 percent, the health of your battery has deteriorated significantly. Boot loops are also a common sign. If you have an older smartphone that starts immediately after meeting a particular battery threshold, it usually depends on an aging lithium ion battery.

The easiest way to recognize the source of the problem is to note when the problem arises. If you have a newer device and start loops after an update or when you close apps, it's probably a software problem.


If your case is not so extreme, you may still want to check your battery's health. We recommend using AccuBattery. It compares the battery's design capacity with its calculated current capacity, which shows how much has been lost over time. Just load the phone after you install it and the app will do the rest.

AccuBattery also offers many other features such as measuring charge rate, how much power applications use, how long the device is in standby mode, and more. If the capacity result is not good, it may be time to change the battery. The good news is that you can do it even if you have a smartphone with a removable battery!

How to replace the smartphone battery

The day for easy changing of batteries is usually over now.

Replacing your smartphone battery used to be as simple as turning off the phone, removing the old battery and inserting the new one. If your smartphone still has a removable battery, you just need to do.

Most Android smartphones come with non-removable batteries, so the task has become more difficult. It is not at all impossible, but it is not a small achievement either.

If you want to go to the DIY route, you need to bring your smartphone together, remove the screen and other parts before you reach the battery. Since most parts are glued together, you must also remove and then re-apply adhesive. Do not try this unless you have the right tool. The basics you need are a suction handle, flat opening tool, tweezers, hot melt adhesive gun and a screwdriver.

Do not just use tools in your house – you can damage your phone.

(iFixit) Changing the battery needs a little more work than what once did.

Unfortunately, it is almost impossible to buy an official battery from an OEM, so we recommend that you stick to proven battery bearings with good grades for repair kits and batteries, such as iFixit. They also provide detailed battery installation guides on their website.

If you already have the necessary tools and have found the appropriate tutorial for your smartphone model, it is important that you first have your battery below 25 percent. Charged lithium ion batteries can catch fire or explode if accidentally punctured. If your battery is swollen when you open the device, do not continue with the replacement, especially if you are inexperienced. Take the phone to an authorized workshop instead.

Although not, you need to be careful. Take the Samsung Galaxy S7 for example. Battery replacement can be quite difficult thanks to a lot of glue, all of which must be reassembled. You also need to disconnect and reconnect the speaker assembly. If you are not careful when doing so, you may need to disassemble your phone to reconnect it. Other phones require you to disconnect even more parts. DIY battery replacement is usually waterproof.

So if you feel you are not patient or skilled, it is best to take or send your smartphone to an authorized service center. For most manufacturers, the battery cost costs less than $ 100 of the warranty, and the process takes about five to seven business days when you submit your mobile phone.

Here are links to popular Android manufacturers (and Apple) that will point you to your nearest authorized service center or give you instructions on how to submit your device to replace the battery:

  • When is battery charging not worth it?

    If you have been attached to your smartphone and just can't stand current devices, it makes sense to try to extend their lifetime, but if it is worth replacing the battery it may be. If you have an older flagship device that you want to keep using for a while, it may be a good investment. If you have a lower unit, the price and the hassle can outweigh the benefits. Most battery replacement at authorized service centers is relatively inexpensive, but it is also new budget phones with updated specification and software.

    For example, Moto G Play costs only $ 199. That is why the better and more convenient option for some is simply to buy a new smartphone, but at the end of the day it is not that personal.

    Replacing the cell phone battery is not as easy as it used to be, but hopefully now you know that there is hope for your expensive flagship even after many years of use.
