Make Your Smartphone Batteries Last

Many smartphones are produced with unibody cases, meaning that you can’t open them and replace the internal battery without having to deal with warranty. Because of this, there’s greater demand to learn how to make your smartphone battery last until the next phone. How should you charge it? What apps to use? Depending on what your battery is, there’s many solutions and ways to make your battery last as long as possible.

What Kind of Battery Do You Have?

There are three batteries that are currently being used for smartphones. Those are Lithium-Ion, (Li-ion) Lithium-Polymer, (LiPo) and Nickel-Cadmium. (NiCd) Most smartphones have a Lithium-Ion, but make sure before you assume. Remove the back cover of your phone and look at the battery. If it’s unibody, look it up or check the manual that came with it.

How to Properly Charge Your Devices

Once you take your device out of the box, you should charge it fully. The manufacturer has specific instructions about this, because the phone discharging after you use it for the first time isn’t good. If you want to make it discharge to see how long it lasts, recharge it fully when you have a low battery. It’s a good idea to do this, as you can see just how long the battery lasts.

But, don’t do it out of the box. Set up your phone, install the apps, and leave it alone for a couple of days. When you start using your device at all times look at the times you charge it, and use it like you would. By seeing how long a low battery lasts, you can change your usage based on that.

Li-ion Batteriesmaking phone battery last

This battery is used in most devices for a reason. It can last longer at higher temperatures. However, if it becomes stressed, it may lose its charge. In fact, you can only charge your battery for so long before it begins to lose its charge for good. This is why you should only charge it at certain times and not as a habit.
Some people just keep their devices charged at all times, but the truth is that your phone needs to discharge once in a while to stay at its peak. To do this, try keeping the charge between 50%-80%. This will give you the best performance. Watch the battery level to do this. Your Li-ion doesn’t need to be fully discharge before recharging.

Discharging the battery before recharging is a myth of Li-ion that has its roots in NiCd cells (see below for more on this). Your Li-ion device does not have a “memory” and it never needs to be fully discharged.

LiPo Batteries

Dealing with the health of these batteries is about the same as a Li-ion, since these batteries are a variation of that. These batteries are formed to your device’s shape, so it’s great for unibody batteries. The HTC One and iPhone 6 use these batteries. Since they are so similar, LiPo batteries work about the same as Li-ion.

Nickel-Cadmium and its Myths

If you have an older device, it more than likely has a NiCd battery. There have been many myths about these batteries and how to take care of them, and they’ve passed down to other batteries too. One example is the memory effect, where people short-circuit their batteries on order to apparently revive them. NiCd batteries are limited to 500 recharges. That means the battery can fail before you’ve had it for two years, and that’s one of the main reasons why smartphones have moved away from this technology.

The memory effect comes from a limit of the material of the batteries, where the substances forms into crystals if you don’t use it. By not discharging every once in a while, your device will not keep a charge. People tried zapping and short circuiting the battery, but it did not fix the memory effect. In fact, you should never fully discharge these, as they can get damaged. Charge when you see the low battery. Also, if you do not use the device, one percent of the battery will be used each day.

Storing and Chargers

Having one charger for every device sounds convenient. Less messy cords, after all. However, if you use the same charger for different devices, it can have problems. Chargers output different amperage’s. Check the fine print in order to figure this out. If you match the voltage and amperage, you can tell if they’re the same chargers. However, most modern devices have the same voltages.

To avoid this headache, just use the charger that came with your device. This will help keep your battery lasting longer. Don’t risk using a knockoff charger if there’s no guarantee you’re going to get the same charge.
If you are not using your device for a bit, leave it around 50% charge in room temperature. Keep it in a safe place where it won’t be pressured, pierced, or dropped. This can damage both your phone and your battery.


Keep your phone cool at all times. Do not leave it in a place over 140 degrees F (60 C.) Aside from forced shutdowns, it can damage your device. If your phone’s hot, this may mean you’ve been gaming too much or watching too many videos. The processor is working like mad, and it can overwork both your phone and your battery. Stop playing if that’s the case.

Having your phone hot can be damaging. It’s never good for computers, and it’s never good for your batteries. Also, while rare, it can cause your battery to catch fire if it’s too hot. Keeping it too cold can hurt your performance and well, though it won’t hurt your battery. Just try keeping it at an average temperature for best results.


Your battery is important. Replacing them is expensive, and if you have a unibody phone, it can even be more of a pain. Just because we live in an age where you don’t have to constantly be buying batteries, it doesn’t mean that you shouldn’t give your batteries special treatment. Keep them charged, and keep them healthy.
