Turn off the automatic time zone feature
Your mobile device can automatically update its time depending on where you are in the world. A small amount of battery power is used because the mobile device determines the correct time via Location Services .
To turn off the automatic time zone feature:
Settings -> Date and time -> Turn off Automatic time zone
Settings -> General -> Date & Time -> move the slider next to Set Automatically to OFF.
Before iOS 7, if you switched between apps by double tapping the home button, the old application (the one you used before) would be frozen, with limited access to system resources.
iOS 7 allowed background applications to periodically refresh their data, and so does iOS 8, so that when you open the application again, you’ll see the latest updates immediately. This can be very useful in certain circumstances, but most of the time is just a waste of battery power to update applications that you don't really need at the moment.
If you want to get the most out of your battery, turning off Background App Refresh should help. You can turn it off entirely, for all apps, or for particular apps, following the steps below:
Go to Settings and tap on General;
Tap on Background App Refresh;
To fully disable it, tap on Background App Refresh and tap on Off;
To disable it for particular apps, choose which applications you want to turn it off for and tap on the toggles next to the apps;

If your battery drains quickly all the time, it might need calibration. This process, called calibration, helps your device estimate its battery life more accurately. It is recommended that you periodically drain your battery totally and then charge it up until it’s completely full (From 0% -100%). You should do this at least once per month.
Please note that calibrating your battery will ensure that you know when you need to charge the battery, but the procedure itself doesn’t actually prolong the durability of the battery.
The system cache partition stores temporary system data. It allows the system to access applications quickly and efficiently, but sometimes it gets cluttered and outdated and drains your battery. A periodic cache clearing can help make the system run more smoothly. It's different from clearing individual app caches, and it won't lead to any loss of personal data or settings.
To wipe cache partition:
Power off the device. If you can't do that using the power button, just remove the battery and insert it after 10 seconds.
Press and hold the Volume (+) up and the Power (Sleep/Wake) buttons. Once your device turns on, let go of the buttons. * If you use a Samsung device, press the Power (Sleep/Wake), Volume (+) up and Home button.
Press the Volume up or Volume down key to navigate through the options. Highlight the Wipe cache partition then press the Power (Sleep/Wake) key to make the selection.
Note: Be careful when you are navigating because there are other important options that you should not modify unless you are an advanced user.
Avoid placing your laptop or mobile device near a radiator or on the dashboard of your car (mobile devices), or near other electronics that are radiating heat.
If a battery gets too hot all the time, it can degrade faster and extreme temperatures can even cause the electrolytes in the battery to ignite and start a fire (though this is an extremely rare situation).
Note (laptop users): You can reduce the temperature of your laptop by placing it on a cooling pad.
Avoid exposing your device to extremely low temperatures because they increase the internal resistance of a lithium-ion battery (used by every mobile device and laptop), by slowing down the electrochemical reactions, causing it to work less efficiently. As such, batteries that are especially cold are likely to see a decrease in performance, i.e they drain quickly.
Luckily, cold conditions have no real long-term effects on a battery, so it should return to normal state once it gets warm.

They can determine what is draining your device's battery even if you don't take it to one of their stores. They will ask you to connect your device to a computer via iTunes and through a utility they can inform you about the actual condition of the battery and will tell you what to do next.
If you have tried all the possible options (replacing the battery, optimising your device in all possible ways and even taking it to a repair store) and none of them worked, consider buying a new mobile device.
If you are not sure which device you want to buy, it would be wiser to ask the salesperson, who will help you make the right choice.

If your battery drains faster and you don't have access to power outlets, you can turn it off if you don't intend to use it. You will save battery and your device will have enough power when you need it the most.
Note: You may also enable an option to show battery percentage, to keep a close eye on the battery, following the steps below:
