So you have heard that Yuasa, the li-ion battery maker for Boeing’s Dreamliner start to give problems, the whole fleet of plans had to be grounded.

You might think that such battery failure is rare but the truth is that it is more common than imagined because Li-ion batteries are one of the most volatile when used incorrectly. For mobile devices, it is the same as something has got to give when you have a power hungry device so here’s the deal. The battery in your Android and iPhone are never made to last more than 18 months. I got a brand new iPod Touch 5G which went kaput within four months of intense use. The end result was a brand new replacement.

My GN wasn’t so fortunate. After 14 months of use. It decided to die on me. This was the original GN battery from Samsung that gave way, to it goes to show that even if you buy branded, chances are that it will eventually fail.

Then my Blackberry Bold failed, battery was a third party product but a high capacity charged version. So that said, I am no stranger to battery failure.

Why Li-ions Fail

There are really just two reason. Over charging and excess HEAT. These are the two main culprits. So lets deal with the first one. Overcharging is very easy to do. This is when you leave the device running while charging at the same time. I know you can’t deal with the fact that your Facebook notifications goes unread during the hours you are fast asleep but heck, you are running down your battery at the same time.

What are Heat Problems

Remember the time I told you that my GN had battery problems because it was running the background apps over and over without stopping? That cause the device to run really hot, contributing to the overall overheating of the whole unit.

Viruses on Android  are also contributing factor when you suddenly find out that the battery you have is draining exceptionally quick after a full charge.

Bad apps, such as those found on both iOS and Android contribute to the demise of your  battery when the app goes OCD by checking and reconnecting for notification updates.

Proper Battery Maintenance

This new finding has also proven that Li-ion Batteries have Memory Effect. This means that the myth that your new Li-ion battery is immune to charge related problems is now busted. You need to maintain your battery to ensure a longer life.

1. Discharge your Battery completely ONCE a month

This is something many of you refuse to do. By discharging your battery completely once a month, you are allowing your battery gauge to recalibrate. Do not do this more than once a month as the recommended discharge recalibration is once every 30 charges. So if you happen to charge your device once a day, then remember to discharge you battery completely once every 30 days.

2. Stop  Running Hot

Never allow your device to run hot as this affects your battery performance. One of the key problems is bad apps and not properly closing games or other apps that stay awake. For example some online games will not allow your device to go into a sleep state. Once in stasis mode, even when the game is not actively running, the battery is consumed as the display is always on. Another problem is related to viruses on the Android platform. If you suspect you have downloaded a bug, just get a virus eradicator like the one from Avast, which will help you stamp out the rogue app that is causing this.

3. Getting a Full Charge versus Partial Charge

If you have charged up your device, then take it out of the charger. Never leave it running as a way to maintain a full charge state. There is this article on Li-ion batteries that you should read. And I quote it here.

Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life.

Forget about what you read about the cut off charge in Li-ion batteries, that too is a myth. There is a trickle charge that makes sure the battery  stays on maximum capacity and this stresses the battery out. So leaving your battery in a charger is never good.

4. Turn Off the Device when Charging

This is to prevent the charger from sending out a trickle charge as a way to top off the battery’s optimum capacity. This might be a hinderance to iPhone or HTC owners who have no access to the battery to allow for some kind of swapping. This continuous charge to top off the capacity is what stresses the battery out. So if you are wondering why your battery isn’t giving you the hours you expect from it, well now you know.

5. Never charge at a higher Voltage

Some devices have built in detectors to monitor the correct voltage input before it allows the device to be charged. This is not a bad thing as some third party chargers promise higher voltage charges just to decrease the amount of charge time at the expense of your battery. If you have a device that doesn’t have such a circuit, then you are pretty much in trouble if you use a third party charger.

I have noticed that my ASUS transformer and iPod Touch won’t charge with just ANY USB charger, meaning they have built in a monitoring circuit to ensure you only use a charger that conforms to the device battery. By charging at a higher voltage, chances are you are damaging your battery by stressing it out. This is what happens when your battery gets bloated like the one in the picture.


All Li-ion batteries have a shelf life. Most of them won’t last more than 400 to 500 cycles of charging, which is good for about a year’s use. Taking into account that you need to charge your battery once a day, that’s 365 times in a year. By taking the correct precautions, you could extend your battery life a bit more than that. For those who are stuck on devices that won’t allow you to swap batteries, fret not. Take out an insurance cover that gives you free maintenance should your device ever break down due to battery related problems. Not all insurance covers are the same as some don’t cover the battery so please remember to read between the lines.


Can I find my LOST Android & iPhone devices?

Hot on the heels on the Apple iOS 7.0 announcement, Lost my iPhone has been updated, with tracking features and password protected login for erasing and resetting your iPhone. Truth is, this is never going to work.

For some years now, mobile devices like the Galaxy S series and iPhones have had a tracking feature. The problem is that it was created with the assumption that the device would be stolen and SIM card intact. this is a wrong assumption.

GPS needs a Data line for Tracking

Yup, the first thing they do is take your SIM card and toss it. Thieves have known that by leaving your SIM card intact in the phone, they will be leading the cops back to their hideout. Find My iPhone is useless with a wifi enabled iPod or iPad—which is what your iPhone would be once the SIM card is removed.

Wiping out your iPhone is easy through Jailbreaking

For Androids, it is just a matter of rooting your phone and resetting it. For iPhones, it is jailbreaking. The only way to protect you data is to wipe it clean. Android has Cerberus while it can’t help you recover your device, it will wipe it clean once the security code is entered wrongly.

Cerberus for Android helps to wipe out your phone.

Your DATA is Precious

I have had my devices stolen in the past, and they accessed my mailbox and used that to steal my Facebook account. Since then, life hasn’t been the same. They hijacked my email box, changed the password to my FB account and tried to lock me out but they forgot to change my phone number security settings, which allowed me to wrestle it back from their evil claws. But even til this day, they are still actively trying to hack their way into my FB account. I get an average of one request for password reset every two days.

The point here is that your email address is the most important element in your mobile device, that single email is your identity to your bank account, credit card and PayPal account, phone billing account, etc. This is why wiping your data clean from you phone is the FIRST thing that must be done.

Recovery of Mobile Device

I urge you to forget this. Regardless if yours was an iPhone or Android device, recovery is not an option if the person who took it is hell bent on reselling your new toy.

Find my iPhone is not fool proof

Find my iPhone is not fool proof

There are so many ways around it with the open Jailbreak. Each time Apple gets a new OS out to iDevies, some clown with a hack will post a work around. And once that happens, you can be assured your device is lost.

What’s more, Apple does not get involved in stolen iPhone or iDevice issues. Even if the device is reported stolen to the Police, Apple will not check with the authorities on every unit returned for repairs.

All mobile devices with an IMEI is trackable. Once the device gets on a carrier network, the telcos can lock it out and prevent it from being used.

But this will never be done for one simple reason, Telcos have a vested interest in getting people on their network and the last thing they want is to stop new users from signing up  their network plans.

Getting your device back also depends on how stupid the culprit has been. If he left it on, with your data line running along with the SIM card, there is a good chance you can hire the local mafia to beat him up. That said, I hope you have solid contacts with the underworld.

Stay Safe, Wipe your Data

The best bet for Android users is to to use a security app like Cerberus, but for the iPhone folks, well, protecting your data is important. If you really want to protect your device from being stolen or lost, then try a mobile device insurance policy. That’s the only way to get it replaced.
