I've read the post and I am slightly confused. In one line you state;
"I go through the day with my phone in my pocket only checking for text messages or emails and by the time school is done (8 hours) I will easily lose 15-30 percent of battery life just doing that."
And then in another you state;
"My phone can't go three hours without dying if I played games."
First I must say, a 15% to 30% reduction in the total charge level over an 8 hour period is not what I would consider excessive, especially given the battery size (1,750mAh). The battery is designed to run the device for an entire average day with a full charge the night before, but depending on your usage pattern and whether you use "computer-like" functions more (surfing, gaming, applications), or phone functions more (calling and texting utilize the phone functions) will have a great impact on the battery's ability to maintain power over the duration of the day.
This is far more a computer than any "Flip-phone" ever was. As a result, it consumes considerably more power. Some of the biggest users of power are;
- The screen
- Much larger, therefore uses more power
- Since it's a Super Active-Matrix Organic Light Emitting Diode (SAMOLED), as opposed to the display on your Flip phone which was likely a back-lit Liquid Crystal Display (LCD), as a result, every point of light on this display is a separate and individual LED, and each one uses power.
- The brighter the screen is, the more power it uses. White is the most power-hungry, black uses almost no power, any color in between will use either more or less power depending on how much closer to white or black it is.
- The longer the display is on while you are not paying attention, such as if you sit it down and turn to do something else, the more power you are wasting while it's staring at the ceiling.
- The 4G radio
- Although 4G is FAST, it also uses more power than 3G, mainly because it actually works WITH 3G, rather than instead of it...2 radios on, at least twice the power consumption.
- Proximity to or quality of reception of 4G signal will impact battery consumption, since if it is having a hard time finding or clearly communicating with a 4G tower, it will "turn up" the power consumption to increase signal to the tower. This in turn uses more battery power.
- The GPS
- Similarly to the 4G signal issues and resulting power consumption, GPS will suck battery power if it is not getting a strong signal from the satellites, such as inside a building.
- Social networking apps
- These apps will not only pull data at intervals throughout the day, but they will do so potentially hundreds of times daily depending on how active the "friends" in your network are and how frequent they post.
- More than one Social network, means more than one app pulling data.
- Each time these apps pull data, they use the cellular data portion of the phone's communication, and whether it's 3G or 4G, it's consuming battery power.
- Many Widgets are also data collection tools, such as clock/weather widgets, news widgets, Social networking widgets, Photo or Media widgets, etc.
- Each time these widgets look for updated data, your battery is being sucked dry by them.
There are LOTS of things you can do to minimize or eliminate battery depletion problems, but you also have to realize that if you use it with screen on for extended periods of time, and especially if watching videos or playing games, the computer portion of the phone will shift into overdrive and draw power from the battery in mass consumption. Take some time to click on the links below and read through the lists of suggestions. Get to know the phone even better than you already do. Try taking advantage of some of the built-in tools that are designed to help you limit battery consumption, and even take advantage of some tried and true tools available on the Google Play Store as well.
