Whenever I write a full specifications of a phone, I like using the mAh unit of charge to calculate the capacity of the phone, since is the official unit used in checking how long a battery will last. Have you ever asked yourself that, how many hours can a 1000mAh, 3000mAh, 4000mAh or more last?
mAh means milli-amp hour and is a unit that measures electric power over time. It’s commonly used for measuring the capacity of a battery. In general or addition, the more mAh, the longer the battery life or capacity.
A higher number means that the battery can store more energy, so, it has a higher capacity. Of course, this also means longer battery life, you can’t compare 3000mAh with 1000mAh because 3000mAh has a lot of stored energy for a given usage.
For instance, it can be used to provide an idea of how a battery will last given a constant of average power draw rate. For instance, a 3000 mAh battery could power a device drawing 100 mA (milliamp) for 30 hours. A device drawing 200 mA would last only 15 hours.
So, your overall usage time will depend on how much current your device is drawing. Like when you are on flight mode, your device won’t consume a lot of current unlike when you are playing games, streaming videos and playing music with 100% full backlight ON.
How long will a 3000mAh battery last?
It can last for 10 hours, if you’re running a fewer apps on your phone, then the current will be less than 300 mA and the battery can last for more than 10 hours. It depends on how you use it.
How long will a 4000mAh battery last?
A 4000mAh or 4100mAh battery capacity should last at least a minimum of 22 hours and 25 hours respectively with whole day mobile data and WiFi usage. If it lasts less than this period, then the background apps are consuming more power than they ideally should be.
Battery with higher capacity are made to give longer period of usage and the more current it consumes, the more it deteriorate. For example, remote controls are made to work when their buttons are pressed but rest a lot when not pressed. So, the more you press it, the more it consumes current.
What’s your say? How many mAh does your phone use and share your experience on how many days it lasts.
