Getting the Most Out of Your Phone Battery
Aside from cracked screens, the main phone complaint we had in the last two years was over batteries. Because the iPhones and Androids have so much more processing power and larger screens, than the Blackberries, they put much higher demands on your battery.
The newer phones do have better batteries, but like any rechargeable batteries, will hold shorter charges over time. There are a few things you can do to improve battery life.
Maintain Battery Life
I have said in the past that it is a good idea to fully charge the phone and then let it run all the way to empty before recharging.
I am now retracting that advice. That was good advice for old nickle based batteries. However, with the newer lithium ion batteries, shallow discharges and frequent recharging is better. Letting your battery run too low can actually cause problems. So charge often, and don't worry about recharging to 100%.
Also, keep your phone in a cool location if possible. Heat can damage the battery. Do not leave your phone sitting above the heating vent or in your car during the summer. It like cool (but not freezing) temperatures best.
Screen Brightness
One of the biggest drains on your battery is the screen. Reducing screen can greatly improve battery life. By default, your phone is set to "auto-brightness" which means it detects when you are in an area with more light and brightens the screen so you can read it. It also darkens the screen a little when possible to save energy.
The problem with auto-brightness is that it tends to greatly over estimate how bright your screen really needs to be. I have screen brightness on my Android set to about 10% above the lowest setting and usually have no trouble reading the screen in any environment. You can find these settings under SETTINGS, DISPLAY, BRIGHTNESS.
On the iPhone the ideal is about 25% above the lowest setting. You can find these settings SETTINGS, DISPLAY & BRIGHTNESS. Feel free to play around with the settings to adjust as you see fit.
Turn off features not needed
Both types of phones have many features that you may not use regularly. These can include Wifi, Bluetooth, NFC (near field communications), GPS, and screen rotation. Since I use some of these, I typically leave them on. For example, I have Wifi on most of the time at home or work. But if I'm in the car all day or will be out and about, I may turn off Wifi since I don't want the phone wasting power continually searching for hotspots. I use bluetooth in my car, but turn it off while at home or work. I tend to leave GPS on as it is convenient for Google Maps. But if you don't use a map feature, you may want to turn it off. I've never used NFC, and leave it off always. Screen rotation tracks the position of your phone and adjusts the screen accordingly. I leave this on, but if you don't care, or it bothers you, turning it off will save on battery drain.
On the Android, it is very easy to access these features to toggle on and off. Just pull down from the top of the screen. You will see a menu of these features. Green means they are turned on. Gray means they are off. Just press the feature to toggle it on or off. There is also a button in the upper right hand corner of this menu that looks a little like the Windows Logo. Press this to see a much larger range of options to turn on or off.
On the iPhone, these changes can be made in SETTINGS. Most of them are right at the top of the main settings menu.
If you are in a location for a long time with a good Wifi spot, you could also turn off your 4G data connection to save power. Just remember to turn it on again when you leave the area or you won't be getting your messages until you remember and turn it on again. I usually leave this on all the time to avoid forgetting.
Turn off Vibrations and Alarms
Running vibrations for alerts such as phone calls or emails can dig into your battery. If you just want an audible notice without the vibration, turn it off and save your battery. You can also turn off audible alerts as well, but I would not do this for power savings alone. It's more of a personal preference how much you want your phone nagging you with alerts.
On the Android, SETTINGS, SOUND to turn of vibrations. You can also turn off sounds or vibrations for keyboards.
On the iPhone, go into SETTINGS, SOUNDS to turn off vibrate or change or disable other sounds.
Turn off apps, or app notifications
You may have installed a great many applications. For example, Facebook, alternate email apps such as Yahoo Mail, various news or sports apps, etc. Many of these applications run in background even if you don't have them open. The regularly check in with their server for updates to notify you of breaking news or other information. Turning off these notifications can save power. There may also be an option to keep an app from running on start up, so that in only runs if you open it. For most apps, this is my preference.
Android allows you to see what Apps are the greatest battery drains on your phone. Go into SETTINGS, BATTERY to see what apps are putting the biggest demand on the battery. If you see one that you really don't use, feel free to disable or delete it. I have not found any similar feature in the iPhone.
In an Emergency
We have all been in the situation where we don't have access to a power source, the phone is getting low on battery and we just want to get through the next few hours. The best method is to power off the phone completely. On either phone, just press and hold the power button then use the power off selection that pops up on the screen. Battery usage falls to near zero and can be maintained for months. You can also greatly limit battery usage by putting the phone in Airplane Mode, which cuts off all data and voice connections. The down side of either of these options is that you need to turn it back on to do anything and won't know if someone calls or emails you. But this can be helpful if you just want to preserve battery until you need it in a few hours. For example, if you are in court and don't want to be bothered anyway, power it off completely and save your battery.
Android phones also have an option called "Ultra Power Save Mode" In this mode, you see only a gray screen with a few basic features available, such as phone and text messaging (email is not available). This can increase your battery time by almost a factor of 10, while still allowing you to make and receive calls. You can set this in SETTINGS, POWER SAVING.
Unfortunately, the iPhone has nothing similar. However, turning off data connections for both cell and Wifi will greatly improve battery life while keeping your phone working.
Buying Power supplements:
Perhaps your phone usage simply won't allow you make it through the day while getting done everything you want. An extra charger at work or in the car can be helpful to keep your device charged, but even these may not cut it.
You can buy external batteries. These are simply lithium batteries that can be charged up, then plugged into your phone when needed to recharge your phone. It can be a handy backup when you need power and are not near a supply. They are inexpensive, you can buy them at Five Below for $5. You do, however, have to remember to carry it around with you, and recharging can be a little clumsy if you can't just let your phone sit while charging.
Android phones also allow you to buy larger capacity batteries from third parties. I have stayed away from this option. Most of the larger batteries are also larger in size, meaning you would need a new back for your phone. It also means your phone case would probably no longer fit. Of course, with iPhone there is not even the option to replace the battery.
A final option is a
Mophie Juice Pack. This looks like a standard cell phone case. But it contains an external battery built into the case. When your phone runs out of power, simply flip a switch on your case, and the built in battery recharges your phone. I find these convenient and easy to use. Only downside is that you must use this as your case, and not one you may like better, and its price $100-$140.
