What is the battery life of this phone?
Is probably the most dreaded question for me or any other reviewer out there. I can totally understand that this is what people like to know but the problem is, there simply isn't a good answer!
When you ask this question a reviewer, you usually get an answer like:
"For ME it lasts a good … days (or hours)"
or an even more convenient answer like:
"It should (easily) get you through the day, maybe even longer..."
Does that mean that this also applies for YOU? No, it doesn't, NOT AT ALL!!!
What if I tell you that a battery lasts for 2 days, you take my word for it, buy the phone only to find out that the battery lasts YOU only a few hours? You'd be pissed, right? That is why I usually try to avoid answering these kind of questions.
The problem is, the battery life or "stand by" time can vary EXTREMLY, there are countless factors that influence the time!
Let's start with the obvious:
Of course we all know that it heavily depends on your usage, what you do with the phone. That is no surprise. We all know that heavy 3D gaming, etc. will drain the battery extremely fast, no surprise there.
Of course everyone should also know that the screen brightness has a MAJOR influence on the battery life, reducing the screen brightness can easy double the battery life. Features like "automatic brightness" on or off can also make a huge difference.
There are also countless other factors that have a HUGE influence on the battery life, some of which some people might not be so aware of.
You need to ask yourself:
Do you have a data connection / Bluetooth / Wifi / GPS on all the time? If so, how good or bad are these connections? Do you have a PERFECT connection ALL the time?
Or is your phone (for example) "fighting" to keep a 3G / 4G / Wifi connection "alive"? THAT can drain the battery a lot!
Do you have push notifications activated? Are you getting SMS / MMS / Whatsapp / e-mails or whatever notifications all the time or maybe just a few times a day?
Do you have weather apps installed that may try to get your (GPS) position constantly or maybe they try to update their data once an hour, every few hours or maybe just once a day?
And how about live wallpapers? Yes, they look "cool" but most of them are a real battery drainers!
One MAJOR problem are apps, that wake up your phone constantly, everything that keeps your phone from getting into a "deep sleep" are a KILLER for the battery life! A lot of times people are not even aware that they might have "deep sleep killers" running on their phones!
Another big problem for ME to give an accurate answer about the battery life is the fact that I USUALLY get my phones at a very "early stage", usually there are not any firmware updates, custom firmwares, tweaks or whatever available at the time I am testing the devices.
A firmware update can also make a HUGE difference when it comes to the battery life! I might test a phone with a firmware A on it, the battery life might suck, two days later the exact same phone might be sold with a firmware B and the battery life might be awesome now! That makes it extremely difficult for any reviewer to make a fair assumption!
As you can see, there are countless factors that have a huge influence on the battery life! That is why I try to avoid this question as good as possible, the way I experience the battery life of a phone might be COMPLETELY different from what YOUR experience might be.
I like to answer: The battery lasts from 2 hours to 3 days.
And you know what? That answer isn't as wrong as you might think ;-)
