How to Add a Longer-Lasting Battery to Your Smartphone

Well, it’s noon and your phone’s battery is already at 37 percent. There are ways to avert this disaster, adding more battery capacity to your favorite smartphone.

Option 1: The Battery Case
The first option you can choose is a battery case. This is exactly what it sounds like. It’s a case you put your phone in — like a typical case designed just to protect your phone — but the case is thicker than normal and includes a built-in battery. The case itelf plugs into your phone’s charging port, and you generally plug the charging cable directly into the case’s charging port when it’s time to charge both your phone and the battery case itself.

Technically, this is just getting a separate battery and carrying it around with you. In practice, a battery case gives your phone more battery power at the cost of increased thickness. The case just becomes part of your phone — you don’t need to carry a separate battery pack in your pocket and attach your phone to it via a cable when it’s time to recharge. Just flip a switch and the battery pack will charge your phone with the power from its own battery. The battery pack can even be charged at the same time you charge your phone, so it’s not even a second device to charge.

This is probably the ideal option for most phones if you consistently need more battery power to make it through a day. Mophie’s line of iPhone battery cases are probably the most well-known, but Mophie has also made cases for other smartphones. They’re not the only company that’s made battery cases, either. Just be sure to get a battery case designed for your specific model of phone so it will fit! Search on Amazon or a similar website and you’ll find many battery cases to choose from.

Option 2: The Aftermarket Battery Replacement
Most phones don’t have user-replaceable batteries anymore, but some do. Samsung’s line of Galaxy phones stand out here, with even the high-end Galaxy S5 and other S-series phones offering user-replaceable batteries. Because these batteries and the entire plastic back panel of the phone can be removed and replaced, it’s possible to get aftermarket batteries that are larger, complete with new back panels to accomodate them.

If you have a phone with a user-replaceable battery, you can probably buy a larger replacement battery for it. The battery and its accompanying back replace your phone’s existing battery, so it’s a more effective solution than a battery case with a battery separate from your phone’s battery. Perform a search for “extended battery” and the name of your phone to find one. For example, you can pick up third-party extended batteries that promise three times the battery life for your Samsung Galaxy S5 for $40 or so on Amazon.

As with a battery case, this will make your phone thicker and larger. Whether that’s worth the trade-off is up to you — if you struggle to make it through a day with your phone’s current battery, it probably will be worth it. But, whatever you do, don’t buy super-cheap battery replacements.

Option 3: Just Carry Around a Separate Battery Pack
There’s also the external battery pack option. Rather than replacing your phone’s battery or adding a battery case, you can just carry a separate battery pack around with you and connect it to your phone with a cable whenever you need to charge your phone away from an outlet. This has the benefit of ensuring your phone stays thin, and you can use the battery pack to charge other devices that might need more power — a tablet, for example.

Editor’s Note: for our recent trip to CES 2015, we bought this RAVPower external battery pack and it worked amazingly well. We were able to recharge an iPhone 6 repeatedly throughout the trip without having to recharge the battery pack at all.

But there are downsides here. The battery pack is yet another thing you have to carry, so it’ll be difficult to pocket and will be more at home in a bag. You’ll have to connect it to your phone via a cable, so you can’t just tuck your phone into your pocket normally and have it charging as you could with a battery case. You’ll also need to charge your battery pack separately, so it’s yet another thing you have to charge at the end of the day.

Still, a battery pack isn’t a bad option. If you only need the extra power for your phone occasionally, it’s a good option you can take with you if you know you’ll be using your phone a lot on a particular day. On days when you won’t be using your phone much, you can take your still-thin phone with you and leave the battery pack at home. However, if you struggle to make it through every single day with your phone’s battery, a battery case or extended battery is a more convenient option you can always take with you and always have in your pocket.

Charging your phone throughout the day can also help. Whenever you’re using your computer, you can plug your smartphone into it via its charging cable — the one with a USB connection — and your phone will charge from the computer. There’s no memory effect with modern batteries, so regularly topping your phone off throughout the day won’t actually damage the battery.

Debunking Battery Life Myths for Mobile Phones, Tablets, and Laptops

Batteries need to be cared for properly — they’re a critical part of our mobile devices and battery technology hasn’t advanced as fast as other technologies. Unfortunately, there’s a lot of incorrect information about batteries out there.

Some of the big myths come from old battery technologies and are actively harmful when applied to new battery technologies. For example, nickel-based batteries needed to be fully discharged, while modern lithium batteries shouldn’t be fully discharged.

Perform Shallow Discharges; Avoid Frequent Full Discharges
Old NiMH and NiCd batteries had a “memory effect” and had to be completely discharged from 100% to 0% to keep their capacity. Modern devices use Lithium Ion batteries, which work differently and have no memory effect. In fact, completely discharging a Li-ion battery is bad for it. You should try to perform shallow discharges — discharge the battery to something like 40-70% before recharging it, for example. Try to never let your battery go below 20% except in rare circumstances.

If you were to discharge your battery to 50%, recharge it, and then discharge it to 50% again, that would count as a single “cycle” with modern Li-ion batteries. You don’t need to worry about performing shallow charges.

There’s only one problem that shallow discharges can cause. Laptops can get a bit confused by shallow discharges and may show you wrong estimates for how long your device’s battery will last. Laptop manufacturers recommend you perform a full discharge about once per month to help calibrate the device’s battery time estimate.

Heat (and Cold) Can Damage Batteries
Heat can reduce a battery’s capacity. This affects all types of devices — even smartphones heat up when performing demanding tasks — but laptops can become hottest of all when under load. The battery is in the laptop, near the electronics that become hot while working heavily — this contributes to battery wear.

If you have a laptop that you use plugged in all of the time and it gets quite hot, removing the battery can increase the battery’s life by limiting the battery’s exposure to the heat of your laptop. This won’t make too much of a difference in normal use, but if you’re using a laptop to play a lot of demanding games and it’s heating up quite a bit, it may be helpful. Of course, this only applies to laptops with removable batteries.

Your climate is also a concern. If it gets very hot where you live or you store your device somewhere that gets very hot — say, a hot car left in the sun on a summer day — your battery will wear down faster. Keep your devices near room temperature and avoid storing them in very hot places, such as hot cars on summer days.

Extreme cold temperatures can decrease the lifespan of your battery, too. Don’t put a spare battery in the freezer or expose any device with a battery to similarly cold temperatures if you’re in a region with cold temperatures.

Don’t Leave the Battery At 0%
You shouldn’t leave the battery in a fully discharged state for very long. Ideally, the battery wouldn’t discharge all the way to zero very often — but if it does, you should recharge it as soon as possible. You don’t have to race to a power outlet when your smartphone dies, but don’t throw it in your drawer and leave it there for weeks without charging it. If you let the battery discharge completely and leave your device in a closet, the battery may become incapable of holding a charge at all, dying completely.

Store Batteries at 50% Charge
On the other hand, leaving the battery charged fully for an extended period of time could result in a loss of capacity and shorten its life. Ideally, you’d store the battery at 50% charge if you weren’t going to use it for a while. Apple recommends you leave the battery at 50% if you intend on storing the device more than six months. If you’re using it regularly, you shouldn’t need to worry about its state — although you never want to leave a battery at 0% for too long.

Storing the battery while fully discharged could result in the battery dying completely, while storing the battery at full charge could result in the loss of some battery capacity and shorten your battery’s life.

This applies to both batteries in devices and spare batteries you may have lying around — keep them at 50% if you won’t be using them for some time.

Leaving Your Laptop Plugged in All The Time Is Okay, But…
This one appears to be fairly controversial. We’ve previously covered the eternal question of whether it’s okay to leave your laptop plugged in all the time. We concluded that it’s okay and the battery’s temperature is the main thing you need to worry about. Apple disagrees, recommending against leaving its Macbook Air and Macbook Pro notebooks plugged in all the time.

Ultimately, we’re both saying the same thing. It’s fine to leave your laptop plugged in at your desk when you’re using it, as the laptop won’t “overcharge” the battery — it will stop charging when it reaches capacity. However, just as you shouldn’t store your laptop’s battery at full capacity in a closet, you shouldn’t leave your laptop plugged in for months on end with the battery at full capacity. Allow your laptop’s battery to occasionally discharge somewhat before charging it back up — that will keep the electrons flowing and keep the battery from losing capacity.

Battery University says that “the worst situation is keeping a fully charged battery at elevated temperatures.” If your laptop produces a lot of heat, removing it might be a good idea. If you have a fairly cool laptop that you occasionally let discharge a reasonable amount, leaving it plugged in — even for days on end — shouldn’t be a problem. If your laptop gets extremely hot, you may want to remove the battery, as we mentioned above.

Batteries Will Always Wear Down
Like all other types of batteries, Li-ion batteries will wear down over time, holding less and less charge. Apple says its laptop batteries will reach 80% of their original capacity after “up to” 1000 full discharge cycles. Other manufacturers commonly rate their batteries 300 to 500 cycles.

The batteries can still be used after this point, but they’ll hold less electricity and will power your devices for shorter and shorter periods of time. They’ll continue losing capacity the more you use them. Heat and aging will reduce the battery’s life, too.

Whatever you do, your devices’ batteries will slowly wear down over time. With proper care, you can make them hold a long charge for longer — but there’s no stopping entropy. Hopefully, your device will be due for an upgrade by the time its battery dies.

How to Choose a Replacement Battery for Your Cell Phone

Most modern cell phones are more than just a communication device; they also serve as a navigation system, a Web browser, a handheld game system, a music player, a day-planner and much more. It’s getting harder and harder to get by without one of these multifunction cell phones. But running all those applications uses a lot of battery power.

Even with cell phone accessories like car chargers and emergency chargers, your battery power may not last long enough. Over time, your cell phone battery will start to degrade and battery life will shorten. When a cell phone battery starts to degrade, you may think of replacing your cell phone altogether. But if your cell phone is still fairly new, it may be less expensive to buy a replacement battery. This guide will help you choose a replacement battery for your cell phone.

Choosing a Replacement Battery:
1.Review your cell phone information.
To get the right type of replacement battery, you will need to know what kind of cell phone you have and what kind of battery is suitable. Most cell phone carriers rename the cell phones that they carry. You need to know the actual name and model number of your cell phone, not the cell phone’s carrier-assigned name, to find a replacement battery. This information can be found in your user manual. You may also want to write down the IMEI number and the battery type and serial number. You can also find it on the inside of your cell phone, usually on a sticker or plaque underneath the battery. Also, review your cell phone purchase information. Many cell phone companies offer a one-year warranty for batteries.

2.Contact your cell phone manufacturer.
You can get cell phone manufacturer information easily on the Web. Ask them if they offer any warranty on the battery or cover the cost of a replacement battery. If they agree to pay for a replacement battery, they may ask for a proof of purchase to reimburse you. Also, don’t forget to check with your cell phone carrier or your cell phone manufacturer to see if using a third-party replacement battery voids the warranty.

3.Purchase a replacement battery.
If both the manufacturer and the cell phone carrier refuse to send you a replacement battery, you will need to find your own battery. You may find batteries made by both the original manufacturer and third-party manufacturers. Do your research before buying. More than one kind of replacement battery might be made with inferior materials or a low percentage of the active ingredient, have less battery power than a quality-made battery or have a short battery life. You don’t want to wind up purchasing another replacement battery in a few months.

Cell Phone Battery Tip
Remember to always dispose of your old cell phone battery by recycling it properly. Search online for places in your neighborhood that recycle dry-cell and rechargeable batteries. There are plenty of free recycling services to help you reduce your environmental impact.

How to Charge a Battery Without a Charger

Have you ever had a dead battery in your camera at just the moment when you need them most? Worse still is a dead cell in an emergency situation. And you can’t always carry a charger with you. For those who like to (or need to) improvise, these recommendations may prove useful.

Using a Battery to Charge a Battery
1.Remove the battery from the device. You will need access to the connection points on the battery. Keep in mind that the battery is not intended to be accessed on certain models of cell phone, so know what can be done with the model you have. On most (but not all) Android and Windows phones the back can be removed with the appropriate amount of pressure in just the right spot. Do not attempt this with most Apple products.

2.Find some AA, AAA, or 9-volt batteries. Unlike the power that comes from the wall outlet (alternating current), the power in common household batteries is no different from that used by your cell phone or camera battery.

Perhaps you are baffled that anyone would suggest using one battery to charge another. Maybe you were expecting some magic trick that would allow you to add charge to your battery without having to find an alternate source of electric power. In fact, that is not possible. One of the fundamental laws of physics (the law of conservation of energy/conservation of mass) makes clear that you can’t get something for nothing.Deal with it.

It is recommended that you charge your battery rather than attempt to hotwire your electronic device and use the alternative batteries directly. Using the improper amount of amperage or voltage can potentially damage complex circuitry, so such methods are obviously not worth the risk.

3.Identify the positive and negative connectors on each battery. On the AAs and other household batteries, these will be marked. For most cell phone batteries, the positive connector will be the one closest to the edge, while the negative connector will usually be the one farthest from the edge (there may be three or four connectors, but the middle one or two are used for temperature regulation and other functions).

4.Match voltage of your battery which need to charge and other battery (AA, AAA or others with enough power to provide). Normally now a day’s Cellphone battery needs more than 3.7V DC to get charged. So multiple AA or AAAs or one 9V battery will be idle for providing a charge. Keep in mind that normal AA or AAA battery on everyday household use provide 1.5V each. So to gain more than 3.7V, you need 3 AA or AAA battery connected in series. 1.5V + 1.5V + 1.5V = 4.5V would be your power source if battery on your hand is either AA or AAA model.

5.Obtain two pieces of metal wire. Ideally, these will be covered in plastic insulation except for exposed ends.

6.Tape or clamp the wires to the battery that will be providing a charge and the battery that requires a charge. These wires may get hot (though most likely they will not if you are doing it properly). It will also take quite a long time to transfer the charge. You don’t want to be holding them the whole time.

If you are using AA and AAA batteries; you may want to connect them to each other “in serie” before attaching them to the battery requiring a charge. This means using wire to connect the negative side of all the small batteries to the negative connector on the battery that needs a charge, and the same for the positive side.

7.After some time, the battery should be charged. Keep in mind that it probably won’t be fully charged, but you should have at least some use of the device that you needed.

Using the Rubbing Trick
1.Remove the battery from the electronic device. Hold it in your hands.

2.Rub the battery hard by using both of your hands to generate enough friction and heat. Continue to do this for 30 seconds to several minutes.

Note: Your battery is not being recharged. Some internet commentators have suggested the rubbing the battery provides it with additional charge, perhaps from built up static electricity.
This interpretation is entirely incorrect.

Lithium ion cells, like all genuine batteries, release electricity as a consequence of chemical reactions. As predicted by the Arrhenius equation, these reactions become more powerful as temperatures increase.[6][7] Essentially, you are improving the conductivity of the battery by raising its temperature.

3.Place the battery back in the electronic device. You may only have a few moments of battery life, so make the most of them.
