SHOW BATTERY PERCENTAGE
It is tough to conserve battery power if you do not know when you should be conserving. By default, there is a battery icon in your notification area but no indicator of exactly how much battery percentage you have left.
You can easily turn this on by moving to
1- Settings
2- Battery
3- Show Battery Percentage – it should now appear in the upper right of your screen at all times.
TURN OFF UNUSED BATTERY HOGGING FEATURES
Not everyone uses the same set of features which is why options and settings exist in the first place. However you may find that a lot of features are turned on by default that you are not using and will never use yet continue to run in the background sucking away your precious battery life.
Here are some settings we recommend you turn off and where you can find them:
1. MOTION GESTURES
Turn all of these off in Settings Motions and gestures. There are 5:
[1]Air Browse
[2 ]Direct call
[3] Smart alert
[4] Mute/pause
[5] Palm to swipe capture.
Some people may like Direct Call and Mute/pause, but we most prefer turning all of them off.
2. SMART STAY
this keeps your screen on while you’re looking at it which obviously needs to continually check to see if you’re looking at the screen. Neat feature but most won’t find it required. Settings > Display > Smart Stay.
3. AIR VIEW
found just below Motion Gestures in Settings
-- Air view.
--It offers a tool-tip style hover features that you will rarely use.
4. TURN OFF BACK BUTTON LIGHT
You know how the back button and the multi-tasking button to the left and right of the home button illuminate when you press them? You can hide those lights completely while keeping full functionality of the buttons. Kind of neat and an option I’ve grown to love. Settings > Display > Touch key light duration > Always off.
TURN ON BATTERY SAVING FEATURES
There are a handful of Galaxy S5 settings that are designed specifically for saving battery life in certain scenarios. Here are some that we recommend turning on and where you can find them:
1. Auto adjust screen tone to save power.
This display setting will adjust your screen done depending on the current picture to save battery life.
-- Settings
-- Display
--Auto adjust screen tone.
2. Keep location on, but turn GPS Off.
Some people like having access to location settings 24/7 but GPS can be one of the biggest battery hogs. Samsung allows you to rely on Wi-Fi and mobile networks to locate you with Power saving mode. It is less accurate but it definitely extends your battery life.
--Settings
-- Location
-- Mode
--- Power saving.
3. Always allow Wi-Fi Scanning.
For the above to work correctly your phone needs to always be scanning for new networks. You need to turn this on by going to
--Settings
--Wi-Fi
-- Wi-Fi Settings via 3 Dots
-- Advanced
--Always allow scanning. Keep in mind that these two features will use MORE battery life than simply turning off location and wi-fi scanning altogether, but if you need location, it’s more efficient than GPS.
PREPARE FOR THE WORST
If you know your battery life is going to enter critical condition territory and you want to protect it in advance, Samsung has added two new features on the Galaxy S5 called Power Saving Mode and Ultra Power Saving Mode.
POWER SAVING MODE
Lets you adjust a number of settings to create a phone profile that conserves battery. Whenever battery life becomes a point of contention, turn it on and it will restrict your phone’s performance with battery in mind. It will block background data, block certain apps, and turn your phone gray scale. It is essentially a “start saving battery” switch that effects a lot of settings in your battery’s favor.
ULTRA POWER SAVING MODE
Offers the same type of functionality but it is much more severe. When you turn it on it will block your access to all apps except for up to 6 allowing you to receive calls and texts but pretty much preventing everything else. You are given information about how long your phone can last in this mode and the numbers are pretty impressive. If you are in a jam, Ultra Power Saving Mode could really save your you-know-what.
You can find both of these features in
--Settings
--Power Saving Mode
--in the bottom of the Device category.
