I am making a pigs ear of inserting this image - bear with me. How do you change the size of the image?
Can anyone explain in laymans terms as to the information being displayed in respect of good/bad points?
Main Screen:
The main screen of GSam Battery Monitor provides you with time estimates, and shows the power drain of various components of your phone such as the Screen, Bluetooth, etc. You can access additional function via the Menu button, or by clicking on a row in the table with a blue > icon on the right.
Time Estimates:
Left - Average: An estimate of remaining time based on usage since the phone was unplugged. Some aspects of this may be controlled through the Power Per Percent setting in the Preferences. This setting should get better over time as the app learns more about your device. Note: The Professional and Kindle Fire editions will show an average for time spent active on devices that have no phones (or that are in 'airplane' mode). This allows a more accurate prediction of how much active use you can get out of the device.
LeftE - Last Xm: An estimate of remaining time based on the device usage over the last X minutes. The maximum X can be is controlled through the Calculate Time Left preference. X may be a small number depending on when statistics were last collected. Statistics aren't collected while the device is not in use, so if you pick up your device after extended sleep time, this number may revert back to 1 and slowly climb as you use the device again.
Left - Talk: An estimate of how much talk time is remaining. Note that this only shows up on devices with phones.
Time to Full: When charging, this represents how long it will take to fully charge the device. Charge time can vary based on charger type (USB vs A/C) and usage of the device while it's charging.
Battery Usage - X% (TIME): X shows the percent of battery consumed based on your time reference (by default since you last unplugged the phone). The TIME section shows the amount of elapsed time since the time reference (typically how long since you unplugged your phone). All statistics have been gathered since the time reference
Phone: How long have you actually spent on the phone - talk time. This is only visible on devices with a phone.
Screen: How long has the screen been on.
Phone Radio: How long has the phone had a signal. Click on this row to get more details, including how long the phone has been at various signal strengths. You can also see the amount of data transferred over your mobile network.
Battery Saving Tip: When your phone spends a long time at lower signal strengths, your battery will be consumed much faster. Consider going into Airplane mode if your in very poor quality signal areas.
Wifi Active: How long has your wifi radio been on with a signal? Click on this row to see the amount of data transferred over your wifi network. Known Issue #1: Some Froyo-based phones don't correctly report a wifi active state. Known Issue #2: When you turn on and off the Wifi radio, all data transferred stats are reset for wifi. So if you turn this on and off a lot, treat your transfer stats with a grain of salt.
Battery Saving Tip: Android is pretty efficient about not using the Wifi unless it's needed, and data transfer over wifi uses less power than over 3G. So leaving it always on isn't a bad thing - just be careful if you have a very weak signal, and it keeps connecting and disconnecting.
Held Awake: This is the amount of time that the phone appears to be sleeping (screen is off), but some application is preventing the phone from going into a deep sleep. This is one of the chief indicators of unneeded battery drain. This is similar to the 'Idle' value in the built-in battery usage, however we don't include the screen on time to help with clarity.
Battery Saving Tip: Apps should not wake your phone up out of a deep sleep. If the Held Awake time seems high to you, go into the App Sucker task, and sort by 'Time Held Awake', and 'Num Times Waking Device'. This can help you identify a misbehaving app
Bluetooth: The amount of time the Bluetooth radio is on.
App Usage: This shows the % of power used by all apps on the phone. Click on this row to go into the App Sucker task where you can view all the details.
Avg. Life: Over time, GSam Battery Monitor averages the amount of time your phone lasts on a given charge. Initially, this number will fluctuate considerably, but over time it should start to level out. You can share this number with your friends, allowing you to compare real-world phone battery life. Does your friend with the same phone get better battery life than yours? Why?
Note 1: You can reset the average value in the Preferences menu - but once you do, you'll have to re-establish your usage patterns.
Note 2: The average is calculated whenever you plug your phone in to charge. You have to have used it for a good amount of time however, or that number will be ignored. For example, if you only used your phone for 15 minutes and re-plugged it back in, GSam Battery Monitor doesn't include that time in it's averaging.
Note 3: On devices without phones, the standby time can be very large (many days). The time you're most interested in is your in-use time, and so for such devices, Avg. Life shows your in-use time rather than your overall average battery life. If you want to see the overall average, click the button and share to an application, and view the text provided - it will include both overall and in-use averages.
