How to improve smart phone’s battery life

battery life

Battery life of smart phone has been main concern for manufacturers, developers and users of modern era. Now a days batteries of smart phones at most last long for 1-2 days. Because of Big screens, Wi-Fi, Bluetooth, GPS and 3G we are never going to get our battery reserves for a week.

Life of a battery mostly depends on the way you use and the way you treat it. There is a notion that CPU is brain and Battery is heart of mobile.

Here are the ways to conserve your smart phones heart i.e. Battery.

Dim your phone Screen


Brightness of your screen will drain the large chunk of battery. Auto- Brightness setting, will keep the screen brightness to the optimum level. Use black or very dark background to save battery. Better to dim the screen whenever possible, because it not only saves battery but also reduce phone’s operating temperature.
Auto brightness mode consumes less power than full brightness mode as it optimizes the brightness level. If possible use phone in lease possible brightness that still enable you to read. This will dramatically increases the life of your battery.

Screen Timeout:

Screen Timeout

Smart phones generally turn off the screen after certain idle time. It is better to keep this time as low as possible to save the battery reserves. Every second matters. So make it shortest available time.

Turn off Wi-Fi, Bluetooth, and Cellular Radios:

turn off bluetooth

Turn off Navigators (GPS):


GPS cause severe strain to battery and consume significant amount of it. You should turn off GPS when you are not using the navigation features. On the other hand you should not allow apps to use GPS unnecessarily. Repeated searches for GPS will dent your battery.

You can revoke apps’ access to location services. You can even set levels of power, howmuch it should use.

Turn off Phone Vibrations

Phone Vibration

Phone vibration will consume more battery than ringtones. It takes less energy to ring your phone than vibrate it for calls, messages and notifications. After all ringtone requires to vibrate a tiny membrane of speakers whereas phone vibration requires shaking of entire phone.

You can leave the phone in view so that you can see whenever a call or message comes, rather than disturbed audibly.

Engage Power Saving Mode:

Power Saving Mode

Recent smart phones come up with new feature called “Ultra Power Saving mode”. It’s better to engage with that feature, whenever batteries are standing on their last legs. It’s has dramatic impact on your battery. Power saving mode prevent apps from updating in the background, reduces screen brightness, screen timeout setting, turnoff vibration etc.

More or less every android phone has power saving feature. Apple iOS doesn’t have a battery saving mode. By default this mode will turn when battery reserves drop to 20 percent.

Signal strength:

Signal Strength

Generally phones always tries to latch up with the strongest possible signal. If you are in poor-cellular coverage area, phone has to work hard to latch up with strong signal. This requires more battery power. It’s better to keep the phone in Airplane if at all possible, to stretch your battery life.

Turnoff notifications:


Each time notification pops up, screen flashes and it consumes battery power. Sometimes notification may give ring, may vibrate the phone depend on the settings, which will further dent the battery reserves. You should avoid notifications from unnecessary apps. You should limit them to most necessary apps.

Keep it cool

Direct exposure to sun light will suck the life of battery. Better to keep the phone out of heat, otherwise it’ll decrease performance of battery overtime. Battery works in optimal way if it is in cooler environment. Battery may run out faster when smartphones are warm.

Switch off when not in use

It would to be great idea to switch the phone off for certain time than leaving it idle. This will save the more battery. You should not charge your phone repeatedly. It’ll eat up battery volume. Every battery has its own number of battery life cycles. We should minimize the charging cycles.

Lithium-Ion (Li-ion) batteries have longer life cycles than Nickel based batteries. I.e. Nickel-Metal Hydride (NiMH) and Nickel-Cadmium (NiCd). Nickel based batteries should be charged when they are run out of power only. Whereas Li-ion based batteries are not supposed to allow to reach zero reserves.


Avoid fast charging: Do it so when only needed.

Turnoff Camera Flash

External Battery Pack or Case

Never go to zero level of battery
