About phone, iPhone battery life

Batteries are usually be advertised as Long Life, High Capacity, Heavy Duty, Fast Charge, Quick Charge, parameters and there are few industries or legal standards defining exactly what each of these terms means. Advertising words can mean whatever the seller wants them to mean. Apart from the basic battery design, performance actually depends on how the batteries are used and also on the environmental conditions under which they are used, but these conditions are rarely, if ever, specified in mass market advertising. For the consumer, this can be very confusing or misleading. The battery industry itself however does not use such vague terms to specify battery performance and specifications normally include a statement defining or limiting the operating or environmental conditions within which the claimed performance can be delivered.

Smartphone and tablets are using Lithium battery, the typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

Tips to prolong your battery life

You don't need to teach your phone the battery's capacity by going from full charge to zero, or zero to full. We recommend you occasionally drain your battery to under 10% and then charge it fully overnight.

Android tips

Android phones, thankfully, have this option “Battery Usage” to show you the details of battery consumption since your last charge.

• Clicks on Settings
• Find and tap on ‘About Device’
• Choose the option “Battery” or “Battery Use”
• Therein, you’ll be able to know how the battery is consumed ranging from Apps/systems to hardware devices.

You can choose to uninstall the apps which you don’t use, but still sucking up the battery. If you find the useful ones consuming a lot of power, you can at least turn off the notifications and pop-ups from these apps.
